More particularly, the present invention relates to a brazed plate heat exchanger comprising a stack of a plurality of heat exchanger plates having a ridge and groove. pattern to form a plurality of plate gaps for fluid exchange heat, wherein the plurality of heat exchanger plates are provided with a plurality of port openings and a skirt extending at least partially around at least a portion of a port opening of the plates . Such plate heat exchangers are used to exchange heat between fluids for various purposes. For example, heat exchangers of this type are used for heating or cooling purposes, such as in a heat pump or cooling system. For example, a heat exchanger of this type is used as an evaporator or a condenser.

多個板式熱交換器在先前技術中是已知的。此種已知的多個板式熱交換器包含用於流體交換熱的多個端口開口及多個板間隙。多個端口開口區域設置在多個端口開口周圍，從而實現所述多個端口開口與該多個板間隙之間的選擇性連通。此多個端口開口區域通常是平坦的且設置成彼此交替地接觸以提供與該多個板間隙的選擇性連通。該多個端口開口區域通常是環形的，圍繞該多個端口開口並設置成選擇性密封一相鄰熱交換器板的一端口開口區域，例如透過硬焊接合。Multiple plate heat exchangers are known in the prior art. Such known multiple plate heat exchangers include multiple port openings and multiple plate gaps for fluid exchange of heat. A plurality of port opening regions are disposed around the plurality of port openings to enable selective communication between the plurality of port openings and the plurality of plate gaps. The plurality of port opening areas are generally flat and arranged in alternating contact with each other to provide selective communication with the plurality of plate gaps. The plurality of port opening regions are generally annular, surrounding the plurality of port openings and arranged to selectively seal a port opening region of an adjacent heat exchanger plate, eg, by brazing.

已知圍繞多個端口開口設置多個裙部以為該流體之一者提供一入口通道。多個腔室在多個裙部與該多個板間隙之間形成。該入口通道透過該多個裙部中的多個孔洞和該多個板中的多個孔洞與該腔室和選定的多個板間隙連通。It is known to provide skirts around port openings to provide an inlet channel for one of the fluids. A plurality of cavities are formed between the plurality of skirts and the plurality of plate gaps. The inlet passage communicates with the chamber and selected plate gaps through holes in the skirts and holes in the plates.

對於部分應用，例如在使用一致冷劑作為該流體之一者的一熱泵應用中，該熱交換器必須能夠承受相對較高的壓力。如果承受高壓，硬焊型板式熱交換器的該多個端口開口區域往往會破裂。For some applications, such as in a heat pump application using a refrigerant as one of the fluids, the heat exchanger must be able to withstand relatively high pressures. The multiple port opening regions of the brazed plate heat exchanger tend to rupture if subjected to high pressure.

因此，先前技術之熱交換器的一個問題是它們很脆弱且不能承受高壓。Therefore, one problem with prior art heat exchangers is that they are fragile and cannot withstand high pressures.

先前技術之熱交換器的另一個問題是它們效率差。Another problem with prior art heat exchangers is that they are inefficient.

先前技術之熱交換器的另一個問題是它們的生產成本可能很高。Another problem with prior art heat exchangers is that they can be expensive to produce.

本發明的一個目的是減輕先前技術熱交換器的問題，以及提供一種具有良好的流體分佈的硬焊型板式熱交換器，這可以產生一種堅固且有效的硬焊型板式熱交換器。根據一些方面，該硬焊型板式熱交換器的生產相對容易且具有成本效益。根據本發明的另外一些方面，一種硬焊型板式熱交換器在各種條件下，例如在低流體流動條件下，具有良好的介質分佈。It is an object of the present invention to alleviate the problems of prior art heat exchangers and to provide a brazed plate heat exchanger with good fluid distribution, which results in a robust and efficient brazed plate heat exchanger. According to some aspects, the brazed plate heat exchanger is relatively easy and cost-effective to produce. According to further aspects of the present invention, a brazed plate heat exchanger has good media distribution under various conditions, such as low fluid flow conditions.

本發明是關於一種硬焊型板式熱交換器，包含一疊至少第一和第二熱交換器板，每個熱交換器板均有一包含脊突和溝槽的圖案，適於在相鄰的熱交換器板之間形成接觸點，使得該多個熱交換器板的多個板對形成交替的多個第一和第二板間隙，用於第一和第二流體在該多個熱交換器板上進行熱交換，其中該多個熱交換器板設有多個端口開口以形成用於該第一和第二流體的入口和出口通道，其中一板對中的該第一和第二熱交換器板之至少一者設有一裙部，該裙部至少部分地圍繞其第一端口開口延伸，以在該裙部和多個板間隙之間形成一腔室，且其中該腔室透過該板對的該第一和第二熱交換器板之一者中的一孔洞與該第一或第二板間隙連通，其特徵在於，該腔室透過該裙部的至少一個自由端部與一相鄰的熱交換器板之間的一間隙通向通道，且該間隙沿該通道的該周圍改變及/或該腔室的一橫截面沿該通道的該周圍改變。該自由端部或該裙部的該自由端與該相鄰的熱交換器板之間的該間隙變化及/或該腔室橫截面的變化導致良好的壓降和流體分佈以在該端口開口周圍分佈該壓力和該應力，並實現該流體從一入口通道均勻有效地流入該多個板間隙。控制該壓降和流體分佈進入該腔室及進一步進入該孔洞並因此進入該板間隙的可能性導致實現能夠承受高壓的一更強熱交換器的可能性。本發明提供了該入口通道中該流體更均勻的流動及改善的在其中的該流體的分佈，其中該熱交換器承受壓力的可能性隨著該裙部處該熱交換器板的壓力更大程度地分佈在其周圍而增加。該熱交換器可以包含在該裙部處的一徑向間隙及/或一軸向間隙，用於流體從該入口通道流到該腔室。該裙部以一偏離該熱交換器板之一平面的一角度延伸，例如通常垂直於該熱交換器板的平面，以形成該入口通道並且還形成該裙部與該多個板間隙之間的該腔室。The present invention relates to a brazed plate heat exchanger comprising a stack of at least first and second heat exchanger plates, each heat exchanger plate having a pattern of ridges and grooves suitable for use in adjacent Contact points are formed between the heat exchanger plates such that the plurality of plate pairs of the plurality of heat exchanger plates form an alternating plurality of first and second plate gaps for the first and second fluids to exchange heat between the plurality of heat exchanger plates heat exchange on heat exchanger plates, wherein the plurality of heat exchanger plates are provided with a plurality of port openings to form inlet and outlet passages for the first and second fluids, wherein the first and second fluids in a pair of plates At least one of the heat exchanger plates is provided with a skirt extending at least partially around its first port opening to form a chamber between the skirt and the plurality of plate gaps, and wherein the chamber passes through A hole in one of the first and second heat exchanger plates of the plate pair is in gap communication with the first or second plate, characterized in that the chamber communicates through at least one free end of the skirt with A gap between an adjacent heat exchanger plate leads to the channel, and the gap varies along the circumference of the channel and/or a cross-section of the chamber varies along the circumference of the channel. The change in the gap between the free end or the free end of the skirt and the adjacent heat exchanger plate and/or the change in the chamber cross-section results in good pressure drop and fluid distribution to the port opening The pressure and the stress are distributed around and uniform and efficient flow of the fluid from an inlet channel into the plurality of plate gaps is achieved. The possibility of controlling the pressure drop and fluid distribution into the chamber and further into the hole and thus into the plate gap leads to the possibility of realizing a stronger heat exchanger capable of withstanding high pressures. The present invention provides a more uniform flow of the fluid in the inlet channel and improved distribution of the fluid therein, wherein the likelihood of the heat exchanger being under pressure increases with the pressure of the heat exchanger plate at the skirt increase in degree distributed around it. The heat exchanger may include a radial gap and/or an axial gap at the skirt for fluid flow from the inlet channel to the chamber. The skirt extends at an angle offset from a plane of the heat exchanger plate, eg generally perpendicular to the plane of the heat exchanger plate, to form the inlet channel and also to form the gap between the skirt and the plurality of plate gaps of the chamber.

離該孔洞越近，該間隙越小，離該孔洞越遠，該間隙越大，使該流體分佈更良好。因此，該間隙的變化可以平衡該入口通道進入該腔室中的該流體分佈。舉例言之，該孔洞的前面沒有間隙。類似地，該腔室的橫截面可以在靠近該孔洞的一位置較小，而在圍繞該入口通道的一方向上遠離該孔洞的一位置較大，以平衡該流體到該腔室的分佈。因此，該腔室的體積圍繞該入口通道朝向該孔洞或包括多個孔洞的一截面減小，例如，使得該腔室的體積在該孔洞與最靠近該孔洞的該裙部部分之間最小。舉例言之，從該孔洞或孔洞的截面看，該腔室在穿過該入口通道的一部分較大。該腔室的橫截面是在該軸向方向的一截面，即，垂直於該板的平面。以下通常以一單孔洞為例。然而，可以使用包含多個孔洞的該熱交換器板的一截面。該孔洞可以是一限制孔洞。舉例言之，該孔洞的面積，或者如果使用多個孔洞，則該多個孔洞的總面積可以顯著小於該入口通道與該腔室之間的該開口的總面積，從而提供流量的限制。The closer to the hole, the smaller the gap, and the farther from the hole, the larger the gap, making the fluid distribution better. Thus, the change in the gap can balance the fluid distribution of the inlet channel into the chamber. For example, there is no gap in front of the hole. Similarly, the cross-section of the chamber may be smaller at a location close to the hole and larger at a location away from the hole in a direction around the inlet channel to balance the distribution of the fluid to the chamber. Thus, the volume of the chamber decreases around the inlet channel towards a cross-section comprising the hole or holes, eg such that the volume of the chamber is minimal between the hole and the skirt portion closest to the hole. For example, the chamber is larger in a portion passing through the inlet channel, viewed from the hole or the cross-section of the hole. The cross section of the chamber is a section in the axial direction, ie perpendicular to the plane of the plate. The following usually takes a single hole as an example. However, a section of the heat exchanger plate containing holes may be used. The hole may be a confinement hole. For example, the area of the hole, or if multiple holes are used, the total area of the plurality of holes can be significantly smaller than the total area of the opening between the inlet channel and the chamber, thereby providing flow restriction.

在一板對中的該第一熱交換器板可以設有一第一裙部，該第一裙部至少部分地圍繞該第一熱交換器板的該第一端口開口，且同一板對中的該第二熱交換器板可以設有一第二裙部，該第二裙部至少部分地圍繞該第二熱交換器板的該第一端口開口。在該第二裙部與該第一裙部的該自由端之間可以設置一徑向間隙。該第一和第二裙部可以實質上沿相反方向延伸。因此，該第一裙部可以提供一流暢的入口通道，其中該第二裙部可以防止流體分佈不均，且該第一和第二裙部可以一起為該腔室提供進入該腔室的不同間隙及/或該腔室的不同橫截面。The first heat exchanger plate in a pair of plates may be provided with a first skirt that at least partially surrounds the first port opening of the first heat exchanger plate, and the The second heat exchanger plate may be provided with a second skirt at least partially surrounding the first port opening of the second heat exchanger plate. A radial gap may be provided between the second skirt and the free end of the first skirt. The first and second skirts may extend in substantially opposite directions. Thus, the first skirt can provide a smooth inlet passage, wherein the second skirt can prevent fluid maldistribution, and the first and second skirts together can provide the chamber with differential access to the chamber gaps and/or different cross-sections of the chamber.

該第一熱交換器板的該第一端口開口可以小於該第二熱交換器板的該第一端口開口。因此，當該第一熱交換器板包含該第一裙部時，將該第一熱交換器板徑向地設置在該第二熱交換器板的該第一端口開口內，以提供該流體一流暢入口及良好分佈。該第一和第二熱交換器板的該多個第一端口開口可以具有一中心軸線，該中心軸線例如可以與該入口通道的中心軸線對齊或者可以相對於該入口通道徑向地偏移(即，偏心)。該多個第二熱交換器板的該多個第一端口開口可以相對於該多個第一熱交換器板的該多個第一端口開口以偏心的方式設置(即，徑向地偏移)，使得該多個第一熱交換器板的該多個第一端口開口與該多個第二熱交換器板的該多個第一端口開口在該軸向方向上不對齊。或者，該第一和第二端口開口具有相似的尺寸及/或彼此對齊。因此，可以以一有效的方式實現該不同間隙及/或該腔室的不同橫截面。The first port opening of the first heat exchanger plate may be smaller than the first port opening of the second heat exchanger plate. Thus, when the first heat exchanger plate includes the first skirt, the first heat exchanger plate is radially positioned within the first port opening of the second heat exchanger plate to provide the fluid A smooth entry and good distribution. The plurality of first port openings of the first and second heat exchanger plates may have a central axis, which may be aligned with a central axis of the inlet passage, for example, or may be radially offset relative to the inlet passage ( That is, eccentric). The plurality of first port openings of the plurality of second heat exchanger plates may be disposed eccentrically (ie, radially offset) relative to the plurality of first port openings of the plurality of first heat exchanger plates ) such that the plurality of first port openings of the plurality of first heat exchanger plates and the plurality of first port openings of the plurality of second heat exchanger plates are not aligned in the axial direction. Alternatively, the first and second port openings are of similar size and/or aligned with each other. Thus, the different gaps and/or the different cross-sections of the chambers can be achieved in an efficient manner.

該多個第一熱交換器板設有圍繞該第一端口開口徑向地延伸的第一端口開口區域，且該多個第二熱交換器板設有圍繞該第一端口開口並接觸一相鄰熱交換器板之該第一端口開口區域徑向地延伸的第二端口開口區域，其中該第二端口開口區域可以設有與該第一端口開口區域不同的一尺寸。因此，可以以一有效的方式實現該不同間隙及/或該腔室的不同橫截面。舉例言之，該第一端口開口面積大於該第二端口開口面積及/或該第一和第二端口開口區域相對於彼此以偏心的方式設置，即，相對於彼此徑向地位移且在該軸向方向上不對齊。The plurality of first heat exchanger plates are provided with a first port opening area extending radially around the first port opening, and the plurality of second heat exchanger plates are provided with a first port opening around the first port opening and contact a phase A second port opening area extending radially adjacent the first port opening area of the heat exchanger plate, wherein the second port opening area may have a different dimension than the first port opening area. Thus, the different gaps and/or the different cross-sections of the chambers can be achieved in an efficient manner. For example, the first port opening area is larger than the second port opening area and/or the first and second port opening areas are arranged eccentrically relative to each other, ie, radially displaced relative to each other and at the Misalignment in the axial direction.

該第一及/或第二裙部可以設置成具有不同的長度、角度及/或形狀，以提供該不同間隙及/或不同的腔室橫截面。The first and/or second skirts may be provided with different lengths, angles and/or shapes to provide the different gaps and/or different chamber cross-sections.

本發明的其他特徵和優勢將從以下實施態樣的說明、附圖和申請專利範圍中變得顯而易見。Other features and advantages of the present invention will become apparent from the following description of embodiments, drawings and claims.

參考圖1，示意性顯示根據本發明一個實施態樣的熱交換器10。熱交換器10包含第一和第二端板11a、11b及多個第一和第二熱交換器板12a、12b堆疊成疊層以形成熱交換器10。熱交換器10是一種硬焊型板式熱交換器。舉例言之，熱交換器10被配置為用作蒸發器或冷凝器，例如在熱泵或冷卻系統中。熱交換器10被配置為至少在第一流體與第二流體之間進行熱交換。舉例言之，其中一種流體是致冷劑，例如R32、R290或類似的致冷劑。Referring to Figure 1, a heat exchanger 10 according to one embodiment of the present invention is schematically shown.

In the case of forming the plate gaps 13a, 13b for fluid exchange of heat, the heat exchanger is formed by providing contact points between at least part of the intersecting ridges R and the grooves G of the adjacent heat exchanger plates 12a, 12b 10, which will be described in more detail below. The pattern according to the embodiment shown is a herringbone pattern. However, the pattern may also be a straight line extending diagonally or other suitable pattern. The pattern of the ridges R and the grooves G is a corrugated pattern with a corrugated depth. The pattern is a pressed pattern. The pattern is suitable for keeping the plates 12a, 12b at a distance from each other (except for contact points) to form plate gaps 13a, 13b between adjacent heat exchanger plates 12a, 12b for heat exchange of fluids. For example, the heat exchanger plates 12a, 12b are made of sheet metal such as stainless steel, copper or other suitable metals or alloys. By way of example, the indentation depth of the heat exchanger plates 12a, 12b is 1 to 3 mm, for example 1 to 2 mm or 1 to 1.7 mm.

在所示實施態樣中，為了沿熱交換器10的周圍提供密封，每個熱交換器板12a、12b被裙部S包圍，該裙部通常垂直於熱交換器板12a、12b的平面延伸且適於接觸相鄰熱交換器板12a、12b的裙部S。In the embodiment shown, in order to provide a seal around the perimeter of the heat exchanger 10, each heat exchanger plate 12a, 12b is surrounded by a skirt S that extends generally perpendicular to the plane of the heat exchanger plates 12a, 12b And adapted to contact the skirt S of the adjacent heat exchanger plates 12a, 12b.

In the embodiment shown, the first end plate 11a and the heat exchanger plates 12a, 12b are provided with four port openings. Alternatively, the heat exchanger plates 12a, 12b are provided with other numbers of port openings, such as six or eight or even more. In the various illustrated embodiments, the first heat exchanger plate 12a is provided with first port openings O1a, wherein the second heat exchanger plate 12b is formed with first port openings O1b. The first port openings O1b of the second heat exchanger plate 12b are different from, for example, the first port openings O1a of the first heat exchanger plate 12a. In the embodiment shown, the first port openings O1a of the first heat exchanger plate 12a are smaller than the first port openings O1b of the second heat exchanger plate 12b, as will be described in more detail below. Alternatively, the first port openings O1a, O1b of the first and second heat exchanger plates 12a, 12b are similar in size.

Port opening areas 15 are provided around port openings O1-O4. Port opening areas 15 are provided to enable selective communication between the port openings O1-O4 and the plate gaps 13a, 13b. For example, the port opening areas 15 are flat and alternately contact each other to provide selective communication. The port opening areas 15 are provided for sealing the respective port opening areas 15 of the adjacent heat exchanger plates 12a, 12b. For example, the port opening regions 15 are substantially flat and are connected to each other by brazing bonds. For example, the port opening area 15 extends in or parallel to the plane of the heat exchanger plates 12a, 12b. For example, the port opening area 15 is annular and has a circular perimeter. Alternatively, the port opening area 15 has an oval perimeter or is formed in another suitable manner.

Alternatively, the heat exchanger plates 12a, 12b are square, eg with rounded corners. Alternatively, the heat exchanger plates 12a, 12b are circular, oval, or arranged in other suitable shapes, with port openings distributed in a suitable manner. In the embodiment shown, the heat exchanger plates 12a, 12b are provided with a chevron pattern, wherein the chevron pattern of the first heat exchanger plate 12a is arranged in one direction and the chevron pattern of the second heat exchanger plate is arranged in the opposite direction set up.

第一熱交換器板12a設有至少部分地圍繞第一熱交換器板12a的第一端口開口O1a。第一裙部16a是例如第一熱交換器板12a的折疊部分，該折疊部分完全或部分圍繞第一端口開口O1a。在所示實施態樣中，第二熱交換器板12b設有至少部分地圍繞第二熱交換器板12b的第一端口開口O1b的第二裙部16b。第二裙部16a可以是第二熱交換器板12b的折疊部分。舉例言之，第一及/或第二端口裙部16a、16b是環形。還參考圖2至7，第一和第二裙部16a、16b圍繞或至少部分地圍繞一對熱交換器板12a、12b的第一端口開口O1a、O1b形成腔室17。腔室17如圖5至7所示。由熱交換器板12a、12b形成的腔室17圍繞由第一端口開口O1a、O1b形成的入口通道14延伸。在所示實施態樣中，腔室17是環形且圍繞入口通道14。舉例言之，腔室17由裙部16a、16b及圍繞第一熱交換器板12a的第一端口開口O1a的端口開口區域15a和圍繞第二熱交換器板12b的第一端口開口O1b的端口開口區域15b形成。所述端口開口區域15a、15b交替地設置在較高和較低的水平面上且圍繞第一端口開口O1a、O1b彼此接合。端口開口區域15a、15b接合相鄰板對的熱交換器板12a、12b的相鄰端口開口區域15a、15b。每個腔室17透過第一和第二熱交換器板12a、12b之一中的孔洞18與第一或第二板間隙13a、13b連通。在圖5的實施態樣中，腔室17透過第一熱交換器板12a中的孔洞18與第二板間隙13b連通。在圖6所示的第二實施態樣中，腔室17透過第二熱交換器板12b中的孔洞18與第二板間隙13b連通。舉例言之，第一和第二熱交換器板12a、12b中的一個設有單個孔洞18。或者，第一和第二熱交換器板12a、12b中的一個在，例如相同區域或分佈在小於一半或小於三分之一的腔室周圍周圍，設有多個孔洞。根據一個實施態樣，孔洞具有至少0.5mm的直徑，例如0.5至2mm或0.5至1.5mm或0.5至1mm。The first heat exchanger plate 12a is provided with first port openings O1a at least partially surrounding the first heat exchanger plate 12a. The first skirt 16a is, for example, a folded portion of the first heat exchanger plate 12a which fully or partially surrounds the first port opening O1a. In the embodiment shown, the second heat exchanger plate 12b is provided with a second skirt 16b at least partially surrounding the first port opening O1b of the second heat exchanger plate 12b. The second skirt 16a may be a folded portion of the second heat exchanger plate 12b. For example, the first and/or second port skirts 16a, 16b are annular. Referring also to Figures 2 to 7, the first and second skirts 16a, 16b form a chamber 17 around or at least partially around the first port openings O1a, O1b of the pair of heat exchanger plates 12a, 12b. The chamber 17 is shown in FIGS. 5 to 7 . The chamber 17 formed by the heat exchanger plates 12a, 12b extends around the inlet channel 14 formed by the first port openings O1a, O1b. In the embodiment shown, the chamber 17 is annular and surrounds the inlet channel 14 . For example, the chamber 17 consists of skirts 16a, 16b and a port opening area 15a surrounding the first port opening O1a of the first heat exchanger plate 12a and ports surrounding the first port opening O1b of the second heat exchanger plate 12b An opening region 15b is formed. Said port opening areas 15a, 15b are arranged alternately at higher and lower levels and engage each other around the first port openings O1a, O1b. The port opening areas 15a, 15b engage adjacent port opening areas 15a, 15b of the heat exchanger plates 12a, 12b of adjacent plate pairs. Each chamber 17 communicates with the first or second plate gap 13a, 13b through a hole 18 in one of the first and second heat exchanger plates 12a, 12b. In the embodiment of FIG. 5, the chamber 17 communicates with the second plate gap 13b through the holes 18 in the first heat exchanger plate 12a. In the second embodiment shown in Figure 6, the chamber 17 communicates with the second plate gap 13b through the holes 18 in the second heat exchanger plate 12b. For example, one of the first and second heat exchanger plates 12a, 12b is provided with a single hole 18 . Alternatively, one of the first and second heat exchanger plates 12a, 12b is provided with a plurality of holes, eg in the same area or distributed around less than half or less than one third of the cavity. According to one embodiment, the holes have a diameter of at least 0.5 mm, such as 0.5 to 2 mm or 0.5 to 1.5 mm or 0.5 to 1 mm.

入口通道14至少部分地沿軸向方向延伸，如圖5中的中心軸線A所示。軸向方向垂直於熱交換器板的平面。第一裙部16a以偏離熱交換器板平面的角度延伸，因此至少部分地在軸向方向上延伸。第一裙部16a具有基部及至少一個自由端部。第一裙部16a以偏離熱交換器板平面的角度從基部朝向自由端延伸。第一裙部16a的基部與自由端之間的距離為其長度。舉例言之，第一裙部的整個長度以偏離熱交換器板平面的角度設置，例如垂直或實質上垂直。舉例言之，第一裙部16a在其整個長度上沿相同方向延伸。在所示實施態樣中，整個第一裙部16a具有自由端且不接觸任何其他裙部或板。第一裙部16a沿朝向其自由端的方向延伸。第一裙部16a實質上沿著入口通道14且平行於中心軸線A的方向上延伸，例如在沿著通過入口通道14軸向流入熱交換器10的流體的方向上，以圖5中的箭頭B示意性表示。在所示實施態樣中，軸向方向垂直於熱交換器板的平面。舉例言之，第一裙部16a在朝向其自由端的方向上實質上軸向延伸且朝向由第一端口開口O1a、O1b形成的通道14的中心軸線A徑向向內傾斜。軸向間隙19設置在相鄰板對中第一裙部16a的自由端與的下一個第一熱交換器板12a的第一裙部16a之間。或者，軸向間隙19在第一裙部16a的自由端與第二熱交換器板12b的端口開口區域15b之間沿軸向方向或實質上沿軸向方向延伸。舉例言之，軸向間隙19在第一裙部16a的自由端與下一個第一裙部16a的基部之間沿軸向方向或實質上沿軸向方向延伸，以圖7中的雙箭頭y示意性表示。因此，腔室17透過軸向間隙19通向入口通道14，使得流體可以從入口通道14通過軸向間隙19進入腔室17。第一裙部16a形成用於流體的流暢入口。The inlet channel 14 extends at least partially in the axial direction, as indicated by the central axis A in FIG. 5 . The axial direction is perpendicular to the plane of the heat exchanger plates. The first skirt 16a extends at an angle deviating from the plane of the heat exchanger plates and thus extends at least partially in the axial direction. The first skirt 16a has a base and at least one free end. The first skirt 16a extends from the base towards the free end at an angle offset from the plane of the heat exchanger plate. The distance between the base and the free end of the first skirt 16a is its length. For example, the entire length of the first skirt is arranged at an angle off the plane of the heat exchanger plates, eg vertical or substantially vertical. For example, the first skirt 16a extends in the same direction over its entire length. In the embodiment shown, the entire first skirt 16a has a free end and does not contact any other skirt or plate. The first skirt 16a extends in a direction towards its free end. The first skirt 16a extends substantially along the inlet channel 14 and in a direction parallel to the central axis A, eg in the direction of the fluid flowing axially into the heat exchanger 10 through the inlet channel 14, as indicated by the arrows in FIG. 5 B is represented schematically. In the embodiment shown, the axial direction is perpendicular to the plane of the heat exchanger plates. For example, the first skirt 16a extends substantially axially in the direction towards its free end and slopes radially inwardly towards the central axis A of the channel 14 formed by the first port openings O1a, O1b. An axial gap 19 is provided between the free end of the first skirt 16a in an adjacent plate pair and the first skirt 16a of the next first heat exchanger plate 12a. Alternatively, the axial gap 19 extends in the axial direction or substantially in the axial direction between the free end of the first skirt 16a and the port opening area 15b of the second heat exchanger plate 12b. For example, the axial gap 19 extends in the axial direction or substantially in the axial direction between the free end of the first skirt 16a and the base of the next first skirt 16a, as double arrow y in FIG. 7 Schematic representation. Thus, the chamber 17 leads through the axial gap 19 to the inlet channel 14 so that fluid can enter the chamber 17 from the inlet channel 14 through the axial gap 19 . The first skirt 16a forms a smooth inlet for fluid.

除了孔洞18或多個孔洞以外，腔室17透過圍繞腔室17的密封區域20與板間隙13a、13b封閉。在所示實施態樣中，密封區域20由板對中的第一和第二熱交換器板12a、12b的平坦區域相互接合而形成。舉例言之，密封區域20由第一熱交換器板12a中的凹陷及/或第二熱交換器板12b中的***形成。舉例言之，第一和第二熱交換器板12a、12b在密封區域20中透過，例如圍繞腔室17的硬焊接合彼此連接。舉例言之，密封區域20是環形。With the exception of the hole 18 or holes, the chamber 17 is closed from the plate gaps 13a, 13b by a sealing area 20 surrounding the chamber 17 . In the embodiment shown, the sealing area 20 is formed by the mutual engagement of the flat areas of the first and second heat exchanger plates 12a, 12b of the plate pair. For example, the sealing area 20 is formed by depressions in the first heat exchanger plate 12a and/or bulges in the second heat exchanger plate 12b. For example, the first and second heat exchanger plates 12a, 12b are permeated in the sealing area 20, eg brazed joints around the chamber 17 are connected to each other. For example, the sealing area 20 is annular.

在所示實施態樣中，第二熱交換器板12b設有第二裙部16b，第二裙部16b實質上沿與第一裙部16a相反的方向延伸。舉例言之，第二裙部16b沿逆著入口通道14中的預期軸向流體流動的方向延伸，如箭頭B所示。第二裙部16b具有基部和自由端，例如類似於第一裙16a。在所示實施態樣中，第二裙部16b的自由端未與第一裙部16a的自由端對齊。因此，第一裙部16a相對於第二裙部16b徑向位移，其中在第一裙部16a與第二裙部16b之間形成徑向間隙21。徑向間隙21在圖7中以雙箭頭x示意性表示。In the embodiment shown, the second heat exchanger plate 12b is provided with a second skirt 16b extending substantially in the opposite direction to the first skirt 16a. For example, the second skirt 16b extends in a direction opposite to the intended axial fluid flow in the inlet passage 14, as indicated by arrow B. The second skirt 16b has a base and a free end, eg similar to the first skirt 16a. In the embodiment shown, the free end of the second skirt 16b is not aligned with the free end of the first skirt 16a. Thus, the first skirt 16a is radially displaced relative to the second skirt 16b, wherein a radial gap 21 is formed between the first skirt 16a and the second skirt 16b. The radial gap 21 is represented schematically by the double arrow x in FIG. 7 .

如圖5所示，第一和第二裙部16a、16b重疊，即，它們的總長度超過在同一板對中與裙部16a、16b相鄰的端口開口區域15a、15b之間的距離。因此，徑向間隙21實質上在第一裙部16a的自由端與第二裙部16b的自由端之間沿徑向方向延伸。第二裙部16b設置在第一裙部16a的徑向外側。因此，第一裙部16a至少在其自由端處設置成具有比第二裙部16b小的直徑。第二裙部16b形成流動防護以防止流體的分佈不均。舉例言之，第二裙部16b形成對氣泡的防護。As shown in Figure 5, the first and second skirts 16a, 16b overlap, ie their total length exceeds the distance between port opening areas 15a, 15b adjacent the skirts 16a, 16b in the same plate pair. Thus, the radial gap 21 extends substantially in the radial direction between the free end of the first skirt 16a and the free end of the second skirt 16b. The second skirt portion 16b is provided on the radially outer side of the first skirt portion 16a. Thus, the first skirt 16a is arranged to have a smaller diameter than the second skirt 16b at least at its free end. The second skirt 16b forms a flow barrier to prevent uneven distribution of the fluid. For example, the second skirt 16b forms a protection against air bubbles.

根據本發明所示的實施態樣，徑向間隙21改變。因此，徑向間隙21在第一裙部16a和第二裙部16b的自由端之間圍繞入口通道14的周圍改變。因此，徑向間隙21在一或多個位置比在其他位置更小。舉例言之，徑向間隙21在較靠近孔洞18的位置處較小且在較遠離孔洞18的位置處較大。根據所示的實施態樣，徑向間隙21在與孔洞18相對的位置處最大，即，在從孔洞18穿過第一端口開口O1a的位置處，且在孔洞18附近進入腔室17中最小。因此，徑向間隙21朝向孔洞18逐漸變細。According to the embodiment of the invention shown, the radial gap 21 varies. Thus, the radial gap 21 varies around the circumference of the inlet channel 14 between the free ends of the first skirt 16a and the second skirt 16b. Therefore, the radial gap 21 is smaller at one or more locations than at other locations. For example, radial gap 21 is smaller at locations closer to hole 18 and larger at locations farther from hole 18 . According to the embodiment shown, the radial gap 21 is largest at the position opposite the hole 18 , ie at the position from the hole 18 through the first port opening O1a, and is smallest near the hole 18 into the chamber 17 . Thus, the radial gap 21 tapers towards the hole 18 .

在所示實施態樣中，第一熱交換器板12a的第一端口開口O1a周圍的端口開口面積15a大於第二熱交換器板12b的第一端口開口O1b周圍的端口開口面積15b。舉例言之，第一熱交換器板12a的第一端口開口O1a周圍的端口開口面積15a在第一熱交換器板12a的第一端口開口O1a周圍的尺寸改變。在所示實施態樣中，第一熱交換器板12a的第一端口開口O1a以偏心的方式設置在端口開口區域15a中。因此，所述端口開口區域15a朝向孔洞18逐漸變細。In the embodiment shown, the port opening area 15a around the first port opening O1a of the first heat exchanger plate 12a is larger than the port opening area 15b around the first port opening O1b of the second heat exchanger plate 12b. For example, the port opening area 15a around the first port opening O1a of the first heat exchanger plate 12a varies in size around the first port opening O1a of the first heat exchanger plate 12a. In the embodiment shown, the first port openings O1a of the first heat exchanger plate 12a are arranged eccentrically in the port opening region 15a. Therefore, the port opening area 15a tapers towards the hole 18 .

在圖5至7的實施例中，腔室17的橫截面在入口通道14周圍實質上恆定。或者，腔室17的橫截面改變，例如使得橫截面在與孔洞18相對的區域中較大，而在孔洞18附近的區域較小。舉例言之，腔室17的橫截面在朝向孔洞18的方向上逐漸變細。In the embodiment of FIGS. 5 to 7 , the cross-section of the chamber 17 is substantially constant around the inlet channel 14 . Alternatively, the cross-section of the chamber 17 is changed, for example, such that the cross-section is larger in the area opposite the hole 18 and smaller in the area near the hole 18 . For example, the cross-section of the chamber 17 tapers in the direction towards the hole 18 .

在所示實施態樣中，裙部16a、16b圍繞第一端口開口O1a、O1b以恆定長度設置。或者，第一裙部及/或第二裙部16b的長度圍繞第一端口開口O1a、O1b的周圍改變。舉例言之，第一裙部16a在靠近孔洞18處較長，其中其長度在遠離孔洞18的方向上減小。因此，軸向間隙19可以在朝向孔洞18的方向上逐漸變細。可以改變第二裙部16b的長度以提供遠離孔洞進入腔室17的較大流量並限制流體流入較靠近孔洞18的腔室。In the embodiment shown, the skirts 16a, 16b are provided at a constant length around the first port openings O1a, O1b. Alternatively, the length of the first skirt and/or the second skirt 16b varies around the circumference of the first port opening O1a, O1b. For example, the first skirt 16a is longer near the hole 18 , wherein its length decreases away from the hole 18 . Thus, the axial gap 19 can taper in the direction towards the bore 18 . The length of the second skirt 16b can be varied to provide greater flow into the chamber 17 away from the bore and restrict fluid flow into the chamber closer to the bore 18 .

在所示實施態樣中，第一端口開口O1a、O1b為圓形，直徑不同且相互偏心。或者，第一及/或第二第一端口開口O1a、O1b是橢圓形，其中徑向間隙21改變。In the embodiment shown, the first port openings O1a, O1b are circular, have different diameters and are eccentric to each other. Alternatively, the first and/or second first port openings O1a, O1b are elliptical, wherein the radial gap 21 varies.

在所示實施態樣中，第一和第二裙部16a、16b實質上在軸向方向上延伸且圍繞第一端口開口O1a、O1b的周圍以恆定的角度向內傾斜。或者，第一及/或第二裙部16a、16b以不同的傾角設置以提供不同的徑向間隙21。In the embodiment shown, the first and second skirts 16a, 16b extend substantially in the axial direction and slope inwardly at a constant angle around the circumference of the first port opening O1a, O1b. Alternatively, the first and/or second skirts 16a, 16b are arranged at different inclination angles to provide different radial gaps 21 .

參考圖8至10，示意性顯示本發明的第三實施態樣。第三實施態樣的熱交換器10包含交替設置的具有壓製圖案的第一和第二熱交換器板12a、12b、端口開口O1-O4、端口開口區域15a、15b及板間隙13a、13b，從而實現如上所述端口開口O1-O4與板間隙13a、13b之間的選擇性連通。8 to 10, a third embodiment of the present invention is schematically shown. The heat exchanger 10 of the third embodiment comprises alternating first and second heat exchanger plates 12a, 12b having a pressing pattern, port openings O1-O4, port opening areas 15a, 15b and plate gaps 13a, 13b, Thereby, selective communication between the port openings O1-O4 and the plate gaps 13a, 13b as described above is achieved.

在第三實施態樣中，第一熱交換器板12a設有裙部16，裙部16部分地圍繞第一熱交換器板12a的第一端口開口O1a延伸，而第二熱交換器板12b可以設置或不設置任何裙部。或者，裙部16圍繞第一端口開口O1a的整個周圍延伸。In the third embodiment, the first heat exchanger plate 12a is provided with a skirt 16 extending partially around the first port opening O1a of the first heat exchanger plate 12a, while the second heat exchanger plate 12b Can be provided with or without any skirt. Alternatively, the skirt 16 extends around the entire circumference of the first port opening O1a.

特別參考圖9和10，裙部16在實質上沿著入口通道14的方向上延伸且選擇性地稍微向內傾斜。裙部16具有至少連接到第一熱交換器板12a的端口開口區域15a的自由端部和基部。在圖9和10中，裙部16具有沿其圍繞入口通道 14 的整個周圍延伸的自由端。軸向間隙19設置在裙部16的自由端與下一個熱交換器板之間。舉例言之，軸向間隙19在裙部16的自由端與第二熱交換器板12b的端口開口區域15b之間沿軸向方向或實質上沿軸向方向延伸，如圖10中的雙箭頭y所示。或者，間隙19可以在裙部16的自由端與下一個裙部16之間延伸，例如實質上在下一個裙部16的基部。With particular reference to Figures 9 and 10, the skirt 16 extends in a direction substantially along the inlet passage 14 and is selectively slightly inwardly inclined. The skirt 16 has a free end and a base connected at least to the port opening area 15a of the first heat exchanger plate 12a. In Figures 9 and 10, the skirt 16 has a free end extending along its entire circumference around the inlet channel 14. An axial gap 19 is provided between the free end of the skirt 16 and the next heat exchanger plate. By way of example, the axial gap 19 extends in the axial direction or substantially in the axial direction between the free end of the skirt 16 and the port opening area 15b of the second heat exchanger plate 12b, as shown by the double arrow in Figure 10 y is shown. Alternatively, the gap 19 may extend between the free end of the skirt 16 and the next skirt 16 , eg substantially at the base of the next skirt 16 .

在圖9和10的實施態樣中，裙部16形成部分圍繞入口通道14的腔室17。因此，裙部16僅沿入口通道14的部分周圍延伸以形成僅部分地圍繞入口通道14的腔室17。裙部16由第一熱交換器板12a的圍繞第一端口開口O1a的折疊部分形成。裙部16被設置成使孔洞18免受從入口通道14流入並進入板間隙13a、13b的流體的影響。因此，裙部16設置在入口通道14與孔洞18之間，其中腔室17設置在入口通道14與孔洞18之間。舉例言之，裙部16圍繞第一端口開口O1a的周圍的至少一半延伸，例如其大約30至90%、40至80%或50至80%。In the embodiment of FIGS. 9 and 10 , the skirt 16 forms a cavity 17 that partially surrounds the inlet channel 14 . Thus, the skirt 16 extends only partially around the inlet channel 14 to form a cavity 17 that only partially surrounds the inlet channel 14 . The skirt 16 is formed by the folded portion of the first heat exchanger plate 12a around the first port opening O1a. The skirt 16 is arranged to shield the holes 18 from fluid flowing from the inlet channel 14 and into the plate gaps 13a, 13b. Thus, the skirt 16 is arranged between the inlet channel 14 and the hole 18 , with the cavity 17 arranged between the inlet channel 14 and the hole 18 . For example, the skirt 16 extends around at least half of the circumference of the first port opening O1a, eg, about 30 to 90%, 40 to 80%, or 50 to 80% thereof.

在第三實施態樣中，裙部16設置為不同長度，並沿遠離孔洞18的方向逐漸變細，從而使軸向間隙19相應地改變。因此，裙部16靠近孔洞18較大，遠離孔洞18長度減小，其中軸向間隙19靠近孔洞18最小，遠離孔洞18較大，使得裙部16的屏蔽效果在孔洞18前面最大。裙部16或第一裙部16a和第二裙部16b的組合可以在孔洞18前面的區域中形成屏蔽，該屏蔽可以在遠離孔洞18的方向上減小，以分配在通道14中流動的流體，並提供從所述通道14進入選定板間隙的更均勻和良好的流體流動。因此，根據替代實施態樣(未顯示)，第二熱交換器板12b設有第二裙部16b，該第二裙部16b可以設置為具有恆定長度且長度可以不同，例如在遠離孔洞18的方向上逐漸變細。In the third embodiment, the skirts 16 are provided with different lengths and taper away from the bore 18, so that the axial gap 19 changes accordingly. Therefore, the skirt 16 is larger near the hole 18 , and has a reduced length away from the hole 18 , wherein the axial gap 19 is the smallest near the hole 18 and larger away from the hole 18 , so that the shielding effect of the skirt 16 is the largest in front of the hole 18 . The skirt 16 or the combination of the first skirt 16a and the second skirt 16b can form a shield in the area in front of the hole 18 which can be reduced away from the hole 18 to distribute the fluid flowing in the channel 14 , and provide more uniform and good fluid flow from the channel 14 into the selected plate gap. Therefore, according to an alternative embodiment (not shown), the second heat exchanger plate 12b is provided with a second skirt 16b which may be provided with a constant length and which may vary in length, for example at a distance away from the holes 18 . Tapered in the direction.

在圖8至10中，如上所述，第二熱交換器板12b在端口開口區域15b與密封區域20之間設有孔洞18，但孔洞18可以替代地設置在第一熱交換器板12a中。In Figures 8 to 10, as described above, the second heat exchanger plate 12b is provided with holes 18 between the port opening area 15b and the sealing area 20, but the holes 18 may alternatively be provided in the first heat exchanger plate 12a .

參考圖11和12，示意性顯示本發明的第四實施態樣。第四實施態樣類似於第三實施態樣，不同之處在於裙部16的一部分接合相鄰的熱交換器板及/或下一個第一熱交換器板12a的裙部16。舉例言之，裙部16在孔洞18前面與相鄰的熱交換器板及/或下一個裙部16接觸，使得孔洞18在入口通道14與孔洞18之間的徑向方向上被完全屏蔽。腔室17設置在入口通道14與孔洞18之間。11 and 12, a fourth embodiment of the present invention is schematically shown. The fourth embodiment is similar to the third embodiment, except that a portion of the skirt 16 engages the skirt 16 of the adjacent heat exchanger plate and/or the next first heat exchanger plate 12a. For example, the skirt 16 contacts the adjacent heat exchanger plate and/or the next skirt 16 in front of the hole 18 so that the hole 18 is completely shielded in the radial direction between the inlet channel 14 and the hole 18 . The chamber 17 is provided between the inlet channel 14 and the hole 18 .

在圖11和12的實施態樣中，裙部16具有至少一個自由端部及一個非自由端部。舉例言之，裙部16在與相鄰板或裙部接觸的端部兩側具有自由端部。如上所述，間隙19設置在自由端部與相鄰板或裙部之間。舉例言之，間隙19是軸向間隙或至少部分地沿軸向方向延伸。間隙19在圖12中以雙箭頭y表示。因此，流體必須從入口通道14流入腔室17，圍繞裙部16在孔洞18前面的部分。流體可以例如通過間隙19流入腔室17。同樣在圖11和12的實施態樣中，裙部16被設置為具有不同長度且在遠離孔洞18的方向上逐漸變細，從而使軸向間隙19相應地改變。因此，裙部16靠近孔洞18較大，遠離孔洞18長度減小，其中孔洞18前面沒有軸向間隙，距離孔洞18越遠間隙19越大。In the embodiment of Figures 11 and 12, the skirt 16 has at least one free end and one non-free end. For example, the skirt 16 has free ends on either side of the end that is in contact with an adjacent panel or skirt. As mentioned above, a gap 19 is provided between the free end and the adjacent plate or skirt. For example, the gap 19 is an axial gap or extends at least partially in the axial direction. The gap 19 is indicated by the double arrow y in FIG. 12 . Therefore, fluid must flow from the inlet channel 14 into the chamber 17 , around the portion of the skirt 16 in front of the hole 18 . Fluid can flow into the chamber 17 , for example, through the gap 19 . Also in the embodiment of FIGS. 11 and 12 , the skirts 16 are provided with different lengths and taper away from the bore 18 , so that the axial gap 19 changes accordingly. Therefore, the skirt 16 is larger near the hole 18 , and has a reduced length away from the hole 18 , wherein there is no axial clearance in front of the hole 18 , and the further away from the hole 18 , the larger the clearance 19 .

裙部16、或第一裙部16a和第二裙部16b的組合，可以在孔洞18前面的區域中形成屏蔽，以分配在通道14中流動的流體，並提供從所述通道14到選定板間隙的更均勻和更良好的流體流動。根據一個實施態樣（未顯示），第一和第二裙部16a、16b在孔洞18的前面相互接合，其中距離孔洞18越遠，它們之間的差距越大。The skirt 16, or the combination of the first skirt 16a and the second skirt 16b, can form a shield in the area in front of the hole 18 to distribute the fluid flowing in the channel 14 and provide the passage from the channel 14 to the selected plate More uniform and better fluid flow of the gap. According to one embodiment (not shown), the first and second skirts 16a, 16b engage each other in front of the hole 18, wherein the further away from the hole 18, the greater the gap between them.

參考圖13至15，示意性顯示本發明的第五實施態樣。根據第五實施態樣，第一和第二裙部16a、16b圍繞第一和第二板12a、12b的第一端口開口O1a、O1b設置且彼此相對，以在第一和第二裙部16a、16b的自由端之間形成軸向間隙19，用於流體從入口通道14流入腔室17。第一和第二裙部16a、16b以從板12a、12b的平面和從端口開口區域15a、15b的平面偏移的角度延伸，例如從端口開口區域15a、15b成90至120度。舉例言之，第一和第二裙部16a、16b實質上沿相反的軸向方向延伸，例如朝向入口通道14的中心稍微向內傾斜。舉例言之，第一和第二裙部16a、16b以類似的長度設置，該長度圍繞整個端口開口是恆定的。舉例言之，第一和第二裙部16a、16b彼此互為鏡像以提供通過入口通道14在兩個方向上的類似流動。在第五實施態樣中，第一裙部16a的自由端實質上面向第二裙部16b的自由端，且它們之間的間隙19圍繞入口通道14的整個周圍是恆定的。舉例言之，第一和第二裙部16a、16b圍繞端口開口O1a、O1b和入口通道14的整個周圍延伸並形成為環形閉合迴路。13 to 15, a fifth embodiment of the present invention is schematically shown. According to the fifth embodiment, the first and second skirts 16a, 16b are disposed around the first port openings O1a, O1b of the first and second plates 12a, 12b and are opposite to each other so as to be in the first and second skirts 16a An axial gap 19 is formed between the free ends of , 16b for fluid to flow from the inlet channel 14 into the chamber 17 . The first and second skirts 16a, 16b extend at angles offset from the plane of the plates 12a, 12b and from the plane of the port opening areas 15a, 15b, eg, 90 to 120 degrees from the port opening areas 15a, 15b. For example, the first and second skirts 16a, 16b extend in substantially opposite axial directions, eg, slope slightly inward toward the center of the inlet channel 14 . For example, the first and second skirts 16a, 16b are provided with similar lengths that are constant around the entire port opening. For example, the first and second skirts 16a, 16b are mirror images of each other to provide similar flow through the inlet channel 14 in both directions. In the fifth embodiment, the free end of the first skirt 16a substantially faces the free end of the second skirt 16b, and the gap 19 between them is constant around the entire circumference of the inlet channel 14 . For example, the first and second skirts 16a, 16b extend around the entire circumference of the port openings O1a, O1b and the inlet channel 14 and form an annular closed loop.

在第五實施態樣中，第一和第二板12a、12b的端口開口區域15a、15b類似，彼此對齊且靠近孔洞18形成為具有較小的寬度。端口開口區域15a、15b是平坦的且在徑向方向上延伸，例如在板12a、12b的平面中或與其平行。第一和第二板12a、12b的第一端口開口O1a、O1b彼此對齊且以偏心的方式設置在端口開口區域15a、15b中，使得腔室17朝向孔洞18逐漸變細，進入第一和第二板間隙13a、13b中的一個。除孔洞18以外，腔室17透過如上所述的密封區域20與第一和第二板間隙13a、13b中的另一個封閉。腔室17在靠近孔洞18處具有較小的橫截面，而在遠離孔洞18處具有較大的橫截面。舉例言之，第一端口開口O1a、O1b以偏心的方式設置在端口開口區域15a、15b中，使得腔室17在朝向孔洞18的方向上逐漸變細。舉例言之，板12a、12b的端口開口區域15a、15b為圓形或橢圓形，其中第一端口開口O1a、O1b為圓形或橢圓形且以偏心的方式設置在端口開口區域15a、15b中。In the fifth embodiment, the port opening regions 15a, 15b of the first and second plates 12a, 12b are similar, aligned with each other and formed with a smaller width near the hole 18. The port opening areas 15a, 15b are flat and extend in a radial direction, eg in or parallel to the plane of the plates 12a, 12b. The first port openings O1a, O1b of the first and second plates 12a, 12b are aligned with each other and are disposed in the port opening areas 15a, 15b in an eccentric manner such that the chamber 17 tapers towards the hole 18 into the first and second plates. One of the two plate gaps 13a, 13b. With the exception of the hole 18, the cavity 17 is closed with the other of the first and second plate gaps 13a, 13b through the sealing area 20 as described above. The chamber 17 has a smaller cross-section near the hole 18 and a larger cross-section away from the hole 18 . By way of example, the first port openings O1a, O1b are arranged in an eccentric manner in the port opening areas 15a, 15b so that the chamber 17 tapers in the direction towards the hole 18 . For example, the port opening areas 15a, 15b of the plates 12a, 12b are circular or oval, wherein the first port openings O1a, O1b are circular or oval and are arranged in an eccentric manner in the port opening areas 15a, 15b .

參考圖16至22，示意性顯示本發明的第六實施態樣。根據第六實施態樣，第一和第二板12a、12b的第一端口開口O1a、O1b是非圓形的且相對於彼此形成徑向延伸的凸部22a、22b和凹部23a、23b。第一和第二裙部16a、16b對應地形成為實質上遵循第一端口開口O1a、O1b的形狀。因此，第一端口開口O1a和第一裙部16a形成有凸部22a和凹部23a，其中第二端口開口O1b和第二裙部16b形成有凸部22b和凹部23b。如上所述，裙部16a、16b實質上沿相反方向軸向延伸且可以向內傾斜。凸部22a、22b和凹部23a、23b圍繞入口通道14的周圍交替設置。凸部22a、22b和凹部23a、23b是彎曲的且可以是多邊形的波浪形，其中多邊形的每個角對應於凹部23a、23b，每個凹部23a、23b之間具有凸部22a、22b。舉例言之，這種類似多邊形的形狀可以，例如具有四個到十個角(例如具有六個凸部22a、22b和六個凹部23a、23b的所示六邊形形狀)。舉例言之，凸部22a、22b和凹部23a、23b圍繞端口開口O1a、O1b和裙部16a、16b的周圍均勻分佈。因此，第一和第二裙部16a、16b設置為周圍波浪形管部分。16 to 22, a sixth embodiment of the present invention is schematically shown. According to the sixth embodiment, the first port openings O1a, O1b of the first and second plates 12a, 12b are non-circular and form radially extending protrusions 22a, 22b and recesses 23a, 23b with respect to each other. The first and second skirts 16a, 16b are correspondingly formed to substantially follow the shape of the first port openings O1a, O1b. Thus, the first port opening O1a and the first skirt portion 16a are formed with the convex portion 22a and the concave portion 23a, wherein the second port opening O1b and the second skirt portion 16b are formed with the convex portion 22b and the concave portion 23b. As mentioned above, the skirts 16a, 16b extend axially in substantially opposite directions and may be inclined inwardly. The convex portions 22a, 22b and the concave portions 23a, 23b are alternately arranged around the circumference of the inlet channel 14. As shown in FIG. The convex portions 22a, 22b and the concave portions 23a, 23b are curved and may be wavy in the shape of a polygon, wherein each corner of the polygon corresponds to the concave portion 23a, 23b with a convex portion 22a, 22b between each concave portion 23a, 23b. For example, such a polygon-like shape may, for example, have four to ten corners (eg, the illustrated hexagonal shape with six protrusions 22a, 22b and six recesses 23a, 23b). For example, the protrusions 22a, 22b and the recesses 23a, 23b are evenly distributed around the periphery of the port openings O1a, O1b and the skirts 16a, 16b. Thus, the first and second skirts 16a, 16b are provided as surrounding corrugated tube portions.

第一板12a的凸部22a位於第二板12b的凹部23b處，反之亦然。因此，凸部22a、22b和凹部23a、23b也在軸向方向上交替。第一板12a的凸部22a在軸向方向上彼此對齊，其中第一板12a的凹部23a彼此對齊。類似地，第二板12b的凸部22b在軸向方向上彼此對齊，其中其凹部23b彼此對齊。舉例言之，對於第一板和第二板12a、12b，凸部22a、22b和凹部23a、23b的頻率相似，但相對於彼此圍繞周圍位移。因此，凸部22a、22b和凹部23a、23b的圖案透過入口通道14圍繞軸線A相對於彼此位移，使得第一板12a的凸部22a沿軸向方向設置在第二板12b的凹部23b的兩側。類似地，第二板12b的凸部22b沿軸向方向設置在第一板12a的凹部23a的兩側。因此，凸部22a、22b徑向突出到入口通道14中以引導流體流進入腔室17。舉例言之，凸部和凹部沿裙部均勻分佈，例如沿其整個周圍分佈。The convex portion 22a of the first plate 12a is located at the concave portion 23b of the second plate 12b, and vice versa. Therefore, the convex portions 22a, 22b and the concave portions 23a, 23b also alternate in the axial direction. The convex portions 22a of the first plate 12a are aligned with each other in the axial direction, wherein the concave portions 23a of the first plate 12a are aligned with each other. Similarly, the convex portions 22b of the second plate 12b are aligned with each other in the axial direction, wherein the concave portions 23b thereof are aligned with each other. For example, for the first and second plates 12a, 12b, the prominences 22a, 22b and the concavities 23a, 23b are similar in frequency, but displaced around the circumference relative to each other. Thus, the pattern of the protrusions 22a, 22b and the recesses 23a, 23b is displaced relative to each other through the inlet channel 14 about the axis A, so that the protrusions 22a of the first plate 12a are arranged in the axial direction at both sides of the recesses 23b of the second plate 12b side. Similarly, the convex portions 22b of the second plate 12b are provided on both sides of the concave portions 23a of the first plate 12a in the axial direction. Thus, the protrusions 22a, 22b protrude radially into the inlet channel 14 to direct fluid flow into the chamber 17 . By way of example, the protrusions and recesses are uniformly distributed along the skirt, eg, along its entire circumference.

舉例言之，在第六實施態樣中，由於相鄰板12a、12b的凸部22a、22b和凹部23a、23b交替重疊，入口通道14與腔室17之間的徑向間隙21圍繞入口通道14的周圍改變。裙部16a、16b的自由端之間的距離可以在軸向方向上是恆定的且在徑向方向上改變，其中徑向間隙21交替改變，從相對的裙部16a、16b的自由端彼此更近的地方變小到它們彼此遠離的地方變大。徑向間隙21交替地從裙部16a、16b的自由端彼此面對的位置處的零變化到凸部22a、22b的中心點與相鄰板12a、12b的凹部23a、23b的中心點對齊的最大尺寸。舉例言之，軸向間隙19是恆定的且可以非常小。For example, in the sixth embodiment, since the convex portions 22a, 22b and the concave portions 23a, 23b of the adjacent plates 12a, 12b alternately overlap, the radial gap 21 between the inlet channel 14 and the chamber 17 surrounds the inlet channel 14 changes around. The distance between the free ends of the skirts 16a, 16b may be constant in the axial direction and vary in the radial direction, with the radial gaps 21 changing alternately, from the free ends of the opposite skirts 16a, 16b further to each other. Close places become smaller to where they are farther away from each other. The radial gap 21 varies alternately from zero at the position where the free ends of the skirts 16a, 16b face each other to a point where the center points of the protrusions 22a, 22b are aligned with the center points of the recesses 23a, 23b of the adjacent plates 12a, 12b biggest size. For example, the axial play 19 is constant and can be very small.
