Description

傳熱體、熱交換單元及傳熱體安裝方法 Heat transfer body, heat exchange unit and heat transfer body installation method

本發明係關於一種用以從被傳熱物散熱或將熱賦予被傳熱物的傳熱體、具備此種傳熱體的熱交換單元以及將此種傳熱體安裝於被傳熱物的傳熱體安裝方法。 The present invention relates to a heat transfer body for dissipating heat from a heat transfer object or imparting heat to the heat transfer object, a heat exchange unit provided with such a heat transfer body, and a device for mounting the heat transfer body on the heat transfer object Installation method of heat transfer body.

自以往以來，為了從發熱的電氣零件或電子零件等被冷卻物進行散熱，乃使用各式各樣種類之物作為散熱體或散熱材。作為此種散熱體等，已知有一種具有平板狀的基部，及從基部的上表面立設而且彼此大致平行地配置的複數個板狀構件者。此外，作為其他種類的散熱體等，亦可使用具有平板狀的基部，及從基部的上表面立設而且配置於網格線之各交點上的複數個棒狀構件者。在此種散熱體等中，至少平板狀的基部為由固體(solid)材(亦即溫度變化也幾乎不會伸縮的構件)所形成。因此，在將散熱體等安裝於被冷卻物之後，當被冷卻物因為外部環境的變化而伸縮時，散熱體等的基部無法與該被冷卻物的伸縮同樣地伸縮，因此會在被冷卻物與散熱體之間產生間隙，故會有冷卻效率降低的問題。 In the past, in order to dissipate heat from objects to be cooled such as heat-generating electrical parts or electronic parts, various kinds of materials have been used as heat sinks or heat sinks. As such a heat sink or the like, there is known a base having a flat plate shape and a plurality of plate-shaped members that are erected from the upper surface of the base and arranged substantially parallel to each other. In addition, as other types of heat sinks, etc., it is also possible to use a base having a flat plate shape, and a plurality of rod-shaped members erected from the upper surface of the base and arranged at each intersection of the grid lines. In such a radiator or the like, at least a flat base is formed of a solid material (that is, a member that hardly expands or contracts even with temperature changes). Therefore, after the radiator, etc., are installed on the object to be cooled, when the object to be cooled expands and contracts due to changes in the external environment, the base of the radiator cannot expand and contract in the same way as the object to be cooled, so it will be on the object to be cooled. There is a gap between the radiator and the heat sink, so there is a problem of reduced cooling efficiency.

此外，作為以往的散熱體等，向來已知有於日本特開平5-299545號公報(JPH05299545(A))、日本特開2000-101005號公報(JP2000101005(A))、日本特開2002-88171號公報(JP2002088171(A))、日本國際專利申請公開公報WO2017/061307A1(JPWO2017061307(A))所揭示者。在此，日本特開平5-299545號公報(JPH05299545(A))、日本特開2000-101005號公報(JP2000101005(A))、日本特開2002-88171號公報(JP2002088171(A))所揭示的散熱體等係形成為大致平板狀。更詳而言之，日本特開平5-299545號公報(JPH05299545(A))所揭示的散熱體，係由選自金屬纖維、金屬細線、金屬箔及陶瓷纖維的至少一種導熱性素材的集合體所構成者。此外，日本特開2000-101005號公報(JP2000101005(A))及日本特開2002-88171號公報(JP2002088171(A))所揭示的散熱材等，係由可撓性(flexible)基材(例如凝膠(gel)狀材料所形成者等)所構成者。 In addition, as conventional heat sinks, etc., Japanese Patent Application Publication No. 5-299545 (JPH05299545(A)), Japanese Patent Application Publication No. 2000-101005 (JP2000101005(A)), and Japanese Patent Application Publication No. 2002-88171 have been known. No. (JP2002088171(A)) and Japanese International Patent Application Publication WO2017/061307A1 (JPWO2017061307(A)). Here, Japanese Patent Application Publication No. 5-299545 (JPH05299545(A)), Japanese Patent Application Publication No. 2000-101005 (JP2000101005(A)), Japanese Patent Application Publication No. 2002-88171 (JP2002088171(A)) disclose The radiator and the like are formed in a substantially flat plate shape. In more detail, the heat sink disclosed in Japanese Patent Application Laid-Open No. 5-299545 (JPH05299545(A)) is an assembly of at least one thermally conductive material selected from metal fibers, thin metal wires, metal foils, and ceramic fibers. Constituted by. In addition, the heat dissipation materials disclosed in Japanese Patent Application Publication No. 2000-101005 (JP2000101005(A)) and Japanese Patent Application Publication No. 2002-88171 (JP2002088171(A)) are made of a flexible substrate (for example, Those formed by gel-like materials, etc.).

此外，日本國際專利申請公開公報WO2017/061307A1(JPWO2017061307(A))所揭示的散熱翼片(fin)，係具有平板狀的基部及從基部的上表面立設而且彼此大致平行地配置的複數個薄板狀的翼片，此等基部及複數個翼片係一體地形成。在此種散熱翼片中，於從厚度方向觀看基材及各翼片時，纖維狀填料(filler)為在基部及各翼片的各者中朝平面方向排列。 In addition, the fins disclosed in Japanese International Patent Application Publication WO2017/061307A1 (JPWO2017061307(A)) have a flat base and a plurality of fins which are erected from the upper surface of the base and arranged substantially parallel to each other. For thin-plate-shaped fins, these bases and a plurality of fins are integrally formed. In such a heat dissipation fin, when the base material and each fin are viewed from the thickness direction, the fibrous filler is arranged in the plane direction in each of the base and each fin.

然而，日本特開平5-299545號公報(JPH05299545(A))所揭示的散熱體，係由選自金屬纖維、金屬細線、金屬箔及陶瓷纖維的至少一種導熱性素材的集合體所構成者，因此在該散熱體的內部形成有間隙，藉由此間隙中所含的空 氣，會帶來隔熱效果。此外，日本特開平5-299545號公報(JPH05299545(A))所揭示的散熱體係平板狀者。依據此等理由，若以日本特開平5-299545號公報(JPH05299545(A))所揭示的散熱體而言，恐有無法從被冷卻物充分地散熱之虞。此外，日本特開2000-101005號公報(JP2000101005(A))及日本特開2002-88171號公報(JP2002088171(A))所揭示的散熱材等係未與被冷卻物接觸，因此恐有無法從該被冷卻物充分地散熱之虞。此外，日本國際專利申請公開公報WO2017/061307A1(JPWO2017061307(A))所揭示的散熱翼片係抄製成形體，在此抄製成形體中，係包含有熱硬化性樹脂、纖維狀填料及粉末狀填料。此時，抄製成形體係成為固體狀者，因此當被冷卻物因為外部環境的變化而伸縮時，散熱翼片的基部無法與被冷卻物的伸縮同樣地伸縮，因此會在被冷卻物與散熱體等之間產生間隙，故有冷卻效率降低之虞。 However, the heat sink disclosed in Japanese Patent Application Laid-Open No. 5-299545 (JPH05299545(A)) is composed of an aggregate of at least one thermally conductive material selected from the group consisting of metal fibers, thin metal wires, metal foils, and ceramic fibers. Therefore, a gap is formed inside the radiator, and the space contained in the gap is Gas will bring about heat insulation effect. In addition, the heat dissipation system disclosed in Japanese Patent Application Laid-Open No. 5-299545 (JPH05299545(A)) has a flat plate shape. For these reasons, the heat sink disclosed in Japanese Patent Application Laid-Open No. 5-299545 (JPH05299545(A)) may not be able to sufficiently dissipate heat from the object to be cooled. In addition, the heat dissipating materials disclosed in Japanese Patent Application Publication No. 2000-101005 (JP2000101005(A)) and Japanese Patent Application Publication No. 2002-88171 (JP2002088171(A)) are not in contact with the object to be cooled. The object to be cooled may sufficiently dissipate heat. In addition, the radiating fin disclosed in Japanese International Patent Application Publication WO2017/061307A1 (JPWO2017061307(A)) is a paper-made body. The paper-made body contains a thermosetting resin, fibrous filler, and powder.状filling. At this time, the copy forming system becomes solid, so when the object to be cooled expands and contracts due to changes in the external environment, the base of the radiating fin cannot expand and contract in the same way as the object to be cooled. There is a gap between the bodies, etc., so the cooling efficiency may decrease.

以下參照圖式來說明本發明的實施型態。圖1至圖7係顯示本實施型態之傳熱體及此種傳熱體之基材被安裝於被傳熱物之熱交換單元的圖。本實施型態之傳熱體，係藉由安裝於發熱的電氣零件或電子零件等被傳熱物而從此等被傳熱物進行散熱者。此外，本實施型態之傳熱體，亦可藉由安裝於供冷卻水 或冷卻氣體等媒介物通過其中之導管(pipe)的外周面，而作為從周圍的環境將熱去除而予以冷卻之熱交換單元的一部分來使用。 Hereinafter, the embodiments of the present invention will be described with reference to the drawings. 1 to 7 are diagrams showing the heat transfer body of this embodiment and the base material of the heat transfer body installed in the heat exchange unit of the heat transfer object. The heat transfer body of this embodiment is one that dissipates heat from the heat-transferred objects such as electric parts or electronic parts that generate heat. In addition, the heat transfer body of this embodiment can also be installed in the cooling water Or a medium such as cooling gas passes through the outer peripheral surface of the pipe, and is used as a part of the heat exchange unit that removes heat from the surrounding environment and cools it.

如圖1至圖3所示，本實施型態之傳熱體10係具備：平板狀的基材20，係要被安裝於被傳熱物；及傳熱部30，係由安裝於基材20的複數個棒狀構件所構成。基材20係至少包含金屬纖維。作為基材20中所包含的金屬纖維，亦可使用金屬被覆纖維。此外，基材20的金屬纖維係濕式或乾式的不織布、織布及網狀物(mesh)等中的至少一者。較佳為使用金屬纖維間結著而成的金屬纖維不織布作為基材20。 As shown in Figures 1 to 3, the heat transfer body 10 of this embodiment is provided with: a flat base material 20, which is to be mounted on the heat transfer object; and a heat transfer part 30, which is mounted on the base material 20 is composed of a plurality of rod-shaped members. The base material 20 contains at least metal fibers. As the metal fiber contained in the base material 20, metal-coated fiber can also be used. In addition, the metal fiber of the base material 20 is at least one of wet or dry non-woven fabric, woven fabric, mesh, and the like. It is preferable to use a metal fiber non-woven fabric formed by bonding metal fibers as the base material 20.

作為構成基材20中所含之金屬纖維之金屬的具體例雖無特別限定，但可為選自由不繡鋼、鐵、銅、鋁、青銅、黃銅、鎳及鉻等所構成之群組者，或是選自由金、白金、銀、鈀、鐒、銥、釕及鋨等所構成之群組的貴金屬。其中，尤以銅纖維及鋁纖維的導熱性優異，而且剛直性與塑性變形性的平衡適度，故較佳。 Although the specific example of the metal constituting the metal fiber contained in the base material 20 is not particularly limited, it may be selected from the group consisting of stainless steel, iron, copper, aluminum, bronze, brass, nickel, and chromium. Those, or precious metals selected from the group consisting of gold, platinum, silver, palladium, samarium, iridium, ruthenium, and osmium. Among them, copper fibers and aluminum fibers are particularly preferred because they have excellent thermal conductivity and a moderate balance between rigidity and plastic deformability.

以下詳述使用纖維間結著而成的金屬纖維不織布作為基材20的情形。金屬纖維不織布係可僅由金屬纖維構成，亦可為具有金屬纖維以及金屬纖維以外者(例如氧化鋁(alumina)粒子等導熱性粒子)。所謂金屬纖維間結著係指金屬纖維物理性地固定的狀態，金屬纖維物理性地固定的部位稱為結著部。在結著部中，係可將金屬纖維彼此直接地固定，亦可將金屬纖維的一部分彼此通過金屬成分以外的成分而間接地固定。就金屬成分以外的成分而言，係可例示聚乙烯(polyethylene)樹脂及聚丙烯(polypropylene)等聚烯烴(polyolefine)樹脂、聚對苯二甲酸乙二酯(polyethylene terephthalate)(PET)樹脂、聚乙烯醇(polyvinyl alcohol)(PVA)樹脂、聚氯乙烯樹脂、聚芳醯胺(aramid)樹脂、尼龍(nylon)及丙烯酸(acrylic) 系樹脂等，以及此等樹脂所構成的纖維狀物。再者，亦可將對於金屬纖維具有結著性及擔持性的有機物等使用於結著部。 Hereinafter, the case of using a metal fiber nonwoven fabric formed by bonding between fibers as the base material 20 will be described in detail. The metal fiber nonwoven fabric system may be composed of only metal fibers, or may have metal fibers and other than metal fibers (for example, thermally conductive particles such as alumina particles). The so-called inter-metal fiber bonding refers to a state where the metal fiber is physically fixed, and the part where the metal fiber is physically fixed is called the knot. In the knot portion, the metal fibers may be directly fixed to each other, or a part of the metal fibers may be indirectly fixed to each other through a component other than the metal component. With regard to components other than metal components, examples include polyethylene resins and polyolefine resins such as polypropylene, polyethylene terephthalate (PET) resins, and polyolefine resins. Polyvinyl alcohol (PVA) resin, polyvinyl chloride resin, aramid resin, nylon and acrylic Series resins, etc., and fibrous materials composed of these resins. In addition, organic substances having binding and holding properties to metal fibers can also be used for the binding portion.

金屬纖維的平均纖維徑雖可在不損及不織布之均質性的範圍內任意地設定，但較佳為1μm至30μm之範圍內的大小，更佳為2μm至20μm之範圍內的大小。若金屬纖維的平均纖維徑為1μm以上，則可獲得金屬纖維之適度的剛直性，因此會有作成不織布時不易產生所謂結塊的傾向。若金屬纖維的平均纖維徑為30μm以下，則可獲得金屬纖維之適度的可撓性，因此會有纖維易於適度交叉的傾向。另外，金屬纖維的平均纖維徑，在對於作成不織布不會造成障礙的範圍內，以較小者更易於提高金屬纖維不織布的均質性，故較佳。此外，本說明書中的「平均纖維徑」係指面積徑的平均值(例如20個纖維的平均值)，該面積徑由算出顯微鏡所拍攝之相對於金屬纖維不織布之長邊方向為任意之垂直剖面中之金屬纖維的剖面積(例如以公知軟體算出)，且算出具有與該剖面積相同面積之圓的直徑所導出者。 Although the average fiber diameter of the metal fiber can be arbitrarily set within a range that does not impair the homogeneity of the non-woven fabric, it is preferably a size in the range of 1 μm to 30 μm, and more preferably a size in the range of 2 μm to 20 μm. If the average fiber diameter of the metal fiber is 1 μm or more, the appropriate rigidity of the metal fiber can be obtained, so there is a tendency that so-called blocking is unlikely to occur when the non-woven fabric is made. If the average fiber diameter of the metal fiber is 30 μm or less, the appropriate flexibility of the metal fiber can be obtained, so the fibers tend to cross appropriately. In addition, the average fiber diameter of the metal fiber is preferably within a range that does not hinder the production of the non-woven fabric, and the smaller one is easier to improve the homogeneity of the metal fiber non-woven fabric. In addition, the "average fiber diameter" in this specification refers to the average value of the area diameter (for example, the average value of 20 fibers), and the area diameter is arbitrarily perpendicular to the long side direction of the metal fiber nonwoven fabric taken by the calculation microscope The cross-sectional area of the metal fiber in the cross-section (for example, calculated by known software), and the diameter of a circle having the same area as the cross-sectional area is calculated.

此外，垂直於金屬纖維之長邊方向的剖面形狀雖可為圓形、橢圓形、大致四角形、不定形等之任一者，但較佳為圓形。在此，所謂圓形剖面，若為在實施金屬纖維不織布的生產上會受到的應力中易於產生曲部之程度的圓剖面形狀即可，故無須為正圓剖面。 In addition, the cross-sectional shape perpendicular to the longitudinal direction of the metal fiber may be any of a circle, an ellipse, a substantially quadrangular shape, and an indefinite shape, but it is preferably a circle. Here, the so-called circular cross-section may be a circular cross-sectional shape that is likely to produce a curved portion in the stress that is received during the production of the metal fiber nonwoven fabric, so it does not need to be a perfect circular cross-section.

金屬纖維的平均纖維長度較佳為1mm至10mm的範圍內，更佳為3mm至5mm的範圍。另外，金屬纖維的纖維長度係在對於作成不織布不會造成障礙的範圍內較短者更易於提高金屬纖維不織布的均質性，故較佳，當平均纖維長度為1mm至10mm的範圍內時，例如藉由抄製製作金屬纖維不織布時，不易於產生所謂之金屬纖維的結塊，而易於控制金屬纖維之分散的程度，並且金屬纖維彼 此會適度地混雜，故亦易於發揮提升金屬纖維不織布之手感(handling)強度的效果。另外，本說明書中的「平均纖維長度」，係以顯微鏡測量20支，且將測量值予以平均所得出的值。 The average fiber length of the metal fiber is preferably in the range of 1 mm to 10 mm, more preferably in the range of 3 mm to 5 mm. In addition, the fiber length of the metal fiber is within the range that does not cause obstacles to making the non-woven fabric, and the shorter one is easier to improve the homogeneity of the metal fiber non-woven fabric. Therefore, it is preferable. When the average fiber length is in the range of 1 mm to 10 mm, for example, When the metal fiber non-woven fabric is made by copying, it is not easy to produce the so-called agglomeration of the metal fiber, and it is easy to control the degree of dispersion of the metal fiber, and the metal fiber is different from each other. This is mixed moderately, so it is easy to exert the effect of improving the handling strength of the metal fiber non-woven fabric. In addition, the "average fiber length" in this manual is a value obtained by measuring 20 fibers with a microscope and averaging the measured values.

另外，亦可使用金屬纖維的織布而非金屬纖維不織布作為基材20。由於金屬纖維的織布亦有可伸縮者，故當使用由此種可伸縮之金屬纖維之織布所構成的基材20時，在被安裝有該基材20的被傳熱物伸縮時，基材20也會隨著伸縮。藉此，即可防止在基材20與被傳熱物之間產生間隙。 In addition, a woven fabric of metal fibers instead of a non-woven fabric of metal fibers may be used as the base material 20. Since metal fiber woven fabrics also have stretchable ones, when the base material 20 composed of such stretchable metal fiber woven fabrics is used, when the heat transfer object on which the base material 20 is mounted stretches and shrinks, The base material 20 will expand and contract accordingly. In this way, it is possible to prevent a gap from being generated between the substrate 20 and the heat-transferred object.

基材20的厚度雖可調整為任意的厚度，但較佳為例如1mm至50mm的範圍內，且更佳為2mm至10mm的範圍內。本說明書中之「基材20的厚度」，係指藉由以空氣中之端子落下方式的膜厚計(例如三豐(mitutoyo)公司製：Digimatic Indicator ID-C112X)，測量任意數之測量點時的平均值。 Although the thickness of the substrate 20 can be adjusted to any thickness, it is preferably in the range of, for example, 1 mm to 50 mm, and more preferably in the range of 2 mm to 10 mm. The "thickness of the substrate 20" in this manual refers to the measurement of an arbitrary number of measurement points by using a film thickness meter (for example, Digimatic Indicator ID-C112X manufactured by Mitutoyo) using a terminal drop method in the air The average value at time.

基材20中之金屬纖維的佔積率較佳為5至50%的範圍內，更佳為15%至40%的範圍內。當金屬纖維的佔積率為5%以上時，金屬纖維的量充足，故可獲得適度的均質性。此外，若金屬纖維的佔積率為50%以下，除適度的均質性外，還可獲得金屬纖維不織布之所希望的可撓性。本說明書中之「基材20中之金屬纖維的佔積率」，係金屬纖維相對於基材20的體積所存在之部分的比例。 The proportion of the metal fiber in the substrate 20 is preferably in the range of 5 to 50%, and more preferably in the range of 15 to 40%. When the proportion of the metal fiber is 5% or more, the amount of the metal fiber is sufficient, so appropriate homogeneity can be obtained. In addition, if the proportion of the metal fiber is 50% or less, in addition to moderate homogeneity, the desired flexibility of the metal fiber non-woven fabric can be obtained. The “occupancy rate of the metal fiber in the base material 20” in this specification refers to the ratio of the metal fiber to the volume of the base material 20.

按照ISO 1924-2：2008(Paper and board-Determination of tensile properties-Part 2：Constant rate of elongation method(20mm/min))之基材20的伸展率(拉伸斷裂伸展)較佳為50ppm至50,000ppm之範圍內的大小，更佳為100ppm至20,000ppm之範圍內的大小，尤佳為200ppm至5,000ppm之範圍內的大小。藉由基材20具有適度的伸展率，當例如基材20沿著絕緣層等被傳熱物折彎時，基材20之折彎部的外側會有伸展裕度，藉此可達成不會挫曲而易於追隨被傳熱物的效果。 具體而言，當基材20的伸展率比100ppm更小時，即使安裝有基材20的被傳熱物伸縮，基材20也無法隨著被傳熱物伸縮，而會有在基材20與被傳熱物之間產生間隙之虞。另一方面，當基材20的伸展率較50,000ppm更大時，會有基材20的強度變弱或基材20的傳熱性變差之虞。此種基材20的伸展率，係依據金屬纖維的平均纖維長度、金屬纖維的平均纖維徑、基材20中之金屬纖維的佔積率、金屬纖維間的距離等而決定。本說明書中之「基材20的伸展率」係指遵照ISO 1924-2：2008測量得出的值。具體而言，係可將試驗片的面積調整為15mm×180mm，且使用拉伸試驗機(A&D公司製 製品名：RTG1210)，以拉伸速度30mm/min進行測量而求出。 According to ISO 1924-2: 2008 (Paper and board-Determination of tensile properties-Part 2: Constant rate of elongation method (20mm/min)), the elongation (tensile breaking elongation) of the substrate 20 is preferably 50 ppm to 50,000 The size within the range of ppm is more preferably the size within the range of 100 ppm to 20,000 ppm, and the size within the range of 200 ppm to 5,000 ppm is particularly preferred. Since the base material 20 has a moderate stretch rate, when the base material 20 is bent along an insulating layer or other heat transfer material, the outer side of the bent portion of the base material 20 will have a stretch margin, which can achieve Frustrated and easy to follow the effect of the heat transfer object. Specifically, when the elongation rate of the base material 20 is less than 100 ppm, even if the heat transfer object on which the base material 20 is mounted expands and contracts, the base material 20 cannot expand or contract with the heat transfer object, and there will be a gap between the base material 20 and There is a risk of gaps between the heat transfer objects. On the other hand, when the elongation rate of the base material 20 is greater than 50,000 ppm, the strength of the base material 20 may be weakened or the heat transfer properties of the base material 20 may be deteriorated. The elongation rate of the substrate 20 is determined based on the average fiber length of the metal fibers, the average fiber diameter of the metal fibers, the occupation rate of the metal fibers in the substrate 20, the distance between the metal fibers, and the like. The "stretch rate of substrate 20" in this manual refers to the value measured in accordance with ISO 1924-2:2008. Specifically, it can be obtained by adjusting the area of the test piece to 15 mm x 180 mm, using a tensile tester (product name: RTG1210, manufactured by A&D), and measuring at a tensile speed of 30 mm/min.

依據本實施型態，基材20係至少包含上述的金屬纖維，因此可使基材20具有柔軟性及對於被傳熱物的追隨性。具體而言，即使當例如安裝有基材20的被傳熱物伸縮時，基材20也會配合此種被傳熱物的伸縮而伸縮，而可防止在被傳熱物與基材20之間形成間隙。 According to this embodiment, the substrate 20 includes at least the aforementioned metal fibers, so that the substrate 20 can have flexibility and followability to the heat-transferred object. Specifically, even when, for example, the heat transfer object on which the substrate 20 is attached expands and contracts, the substrate 20 expands and contracts in accordance with the expansion and contraction of the heat transfer object, and it can prevent the heat transfer object and the substrate 20 from being A gap is formed between.

接著說明傳熱部30的構成。如圖1至圖3所示，傳熱部30係具有從基材20朝外側延伸的複數個棒狀構件，各棒狀構件係配置於網格線的各交點上。此種各棒狀構件係例如由金屬等所構成。更佳為，構成基材20中所含之金屬纖維之金屬的種類和構成傳熱部30之各棒狀構件之金屬的種類係相同。此時，藉由將基材20及傳熱部30由相同種類的金屬而形成，即可抑制在基材20與傳熱部30之間產生界面腐蝕。亦即，當構成基材20中所含之金屬纖維之金屬的種類和構成傳熱部30之各棒狀構件之金屬的種類不同時，會有因為兩者金屬間的電位差而使電流流動進而導致於金屬形成孔洞之虞。 Next, the structure of the heat transfer unit 30 will be described. As shown in FIGS. 1 to 3, the heat transfer portion 30 has a plurality of rod-shaped members extending outward from the base 20, and each rod-shaped member is arranged at each intersection of the grid lines. Each such rod-shaped member is made of, for example, metal. More preferably, the type of metal constituting the metal fiber contained in the base 20 and the type of metal constituting each rod-shaped member of the heat transfer portion 30 are the same. At this time, by forming the base material 20 and the heat transfer part 30 from the same kind of metal, it is possible to suppress the occurrence of interfacial corrosion between the base material 20 and the heat transfer part 30. That is, when the type of metal constituting the metal fiber contained in the base material 20 and the type of metal constituting the rod-shaped members of the heat transfer portion 30 are different, the electric current may flow due to the potential difference between the two metals. Causes the possibility of forming holes in the metal.

綜上所述，較佳為構成基材20中所含之金屬纖維之金屬的種類和構成傳熱部30之各棒狀構件之金屬的種類相同，但本實施型態不限定於此種態樣。作為其他態樣，亦可使用構成基材20中所含之金屬纖維之金屬的種類和構成傳熱部30之各棒狀構件之金屬的種類彼此不同的傳熱體10。 In summary, it is preferable that the type of metal constituting the metal fiber contained in the base material 20 and the type of metal constituting the rod-shaped members of the heat transfer portion 30 are the same, but the present embodiment is not limited to this state. Sample. As another aspect, the type of metal constituting the metal fiber contained in the base material 20 and the type of metal constituting the rod-shaped members of the heat transfer portion 30 may be different from each other in the heat transfer body 10.

此外，如圖3及圖4所示，構成傳熱部30的各棒狀構件的一部分融接於基材20的金屬纖維，其他部分則露出。另外，如圖4所示，構成傳熱部30之各棒狀構件的端部，亦可在基材20的厚度方向上延伸至該基材20之中途的位置。或者，如圖5所示，構成傳熱部30的各棒狀構件，亦可貫通基材20。在本說明書中，所謂「融接於基材20的金屬纖維」，係包含燒結、藉由傳熱性物質進行的接合等。 In addition, as shown in FIGS. 3 and 4, a part of each rod-shaped member constituting the heat transfer portion 30 is fused to the metal fiber of the base material 20, and other parts are exposed. In addition, as shown in FIG. 4, the end of each rod-shaped member constituting the heat transfer portion 30 may extend to a position in the middle of the base 20 in the thickness direction of the base 20. Or, as shown in FIG. 5, each rod-shaped member which comprises the heat transfer part 30 may penetrate the base material 20. As shown in FIG. In this specification, the "metal fiber fused to the base material 20" includes sintering, joining by a heat transfer substance, and the like.

例如，構成傳熱部30之各棒狀構件的長度較佳為0.5至50mm之範圍內的大小，更佳為1mm至30mm之範圍內的大小。尤佳為構成傳熱部30之各棒狀構件的長度係5mm至20mm之範圍內的大小。此外，構成傳熱部30之各棒狀構件的直徑，較佳為0.1至5mm之範圍內的大小，更佳為0.5至3mm之範圍內的大小。若為此範圍內，可獲得充分的傳熱效果。 For example, the length of each rod-shaped member constituting the heat transfer portion 30 is preferably a size in the range of 0.5 to 50 mm, and more preferably a size in the range of 1 mm to 30 mm. It is particularly preferable that the length of each rod-shaped member constituting the heat transfer portion 30 is a size in the range of 5 mm to 20 mm. In addition, the diameter of each rod-shaped member constituting the heat transfer portion 30 is preferably a size in the range of 0.1 to 5 mm, and more preferably a size in the range of 0.5 to 3 mm. If it is within this range, a sufficient heat transfer effect can be obtained.

茲說明具備此種基材20及傳熱部30之傳熱體10的製造方法。首先，使金屬纖維等分散於水中以獲得抄製漿液(slurry)。接著將所獲得的抄製漿液投入於批次(batch)式抄製裝置。然後，在被投入有抄製漿液的批次式抄製裝置的槽內，將作為傳熱部30的棒狀構件，以於下部接觸抄製網且上部為固定的狀態下進行設置。之後，進行濾水，從而可獲得在至少包含金屬纖維的基材20上有傳熱部30之各棒狀構件朝法線方向直立而成的傳熱體10。另外，亦可於濾水之後，使作為傳熱部30的棒狀構件立於基材20。再者，可在保持著傳熱部30的各棒狀構件 朝法線方向立於基材20的狀態下，於例如氫氣75%、氮氣25%的氣體環境中進行燒結，從而獲得構成傳熱部30之棒狀構件的一部分融接於基材20之金屬纖維而成的傳熱體10。 Hereinafter, a manufacturing method of the heat transfer body 10 provided with such a base material 20 and a heat transfer part 30 will be described. First, disperse metal fibers and the like in water to obtain a slurry. Next, the obtained papermaking slurry was put into a batch type papermaking apparatus. Then, in the tank of the batch-type papermaking apparatus into which the papermaking slurry is put, the rod-shaped member as the heat transfer section 30 is installed in a state where the lower part is in contact with the papermaking net and the upper part is fixed. After that, the water is filtered to obtain the heat transfer body 10 in which each rod-shaped member having the heat transfer portion 30 on the base material 20 containing at least metal fibers stands upright in the normal direction. In addition, after filtering the water, the rod-shaped member as the heat transfer portion 30 may be made to stand on the base 20. Furthermore, the rod-shaped members holding the heat transfer portion 30 can be Standing on the substrate 20 in the normal direction, sintering is performed in a gas atmosphere of, for example, 75% hydrogen and 25% nitrogen, so as to obtain a part of the rod-shaped member constituting the heat transfer portion 30 fused to the metal of the substrate 20 Heat transfer body 10 made of fibers.

接著說明將傳熱體10安裝於被傳熱物的方法。首先說明進行發熱之電氣零件或電子零件等被傳熱物之散熱的情形。為了進行被傳熱物的散熱，將傳熱體10的基材20安裝於被傳熱物。當被傳熱物中之供基材20安裝的部位為平面時，係藉由融接、栓鎖、螺絲固定、接著劑等將傳熱體10的基材20安裝於被傳熱物。此外，亦可僅在被傳熱物的上方載置傳熱體10的基材20，以取代將傳熱體10的基材20安裝於被傳熱物。此外，即使被傳熱物中之供基材20安裝的部位非為平面而為曲面或凹凸面、粗面，由於基材20至少包含金屬纖維，因此可使基材20沿著被傳熱物中之供基材20安裝之部位的形狀變形，藉此可抑制在基材20與被傳熱物之間產生間隙。 Next, a method of attaching the heat transfer body 10 to the heat transfer object will be described. First of all, the heat dissipation of heat transfer materials such as electric parts or electronic parts that generate heat will be explained. In order to perform heat dissipation of the heat transfer object, the base 20 of the heat transfer body 10 is attached to the heat transfer object. When the part of the heat transfer object where the substrate 20 is installed is flat, the substrate 20 of the heat transfer body 10 is installed on the heat transfer object by fusion, bolting, screw fixing, adhesive, and the like. In addition, instead of attaching the base 20 of the heat transfer body 10 to the heat transfer target, only the base 20 of the heat transfer body 10 may be placed above the target heat transfer. In addition, even if the part where the substrate 20 is installed in the heat transfer material is not a flat surface but a curved surface, uneven surface, or rough surface, since the substrate 20 contains at least metal fibers, the substrate 20 can be moved along the heat transfer object. The shape of the part where the substrate 20 is installed is deformed, thereby suppressing the generation of a gap between the substrate 20 and the heat-transferred object.

在將傳熱體10的基材20安裝於被傳熱物時，在基材20之中，或在基材20與被傳熱物之間，亦可注入導熱性油脂(grease)等傳熱輔助劑。作為傳熱輔助劑，可使用液狀的樹脂，較佳為使用液狀的熱硬化性樹脂。此外，作為傳熱輔助劑，亦可使用包含導熱性填料的液狀橡膠。藉由將此種傳熱輔助劑注入於基材20之中，或注入基材20與被傳熱物之間，即可效率更佳地從被傳熱物散熱。尤其當基材20包含金屬纖維不織布時，金屬纖維不織布將可兼作為傳熱輔助劑的保持體，且可使基材20保持傳熱輔助劑，因此即使被傳熱物伸縮亦可抑制傳熱輔助劑從基材20之中或基材20與被傳熱物之間洩漏。 When the base 20 of the heat transfer body 10 is mounted on the heat-transferred object, the base 20 or between the base 20 and the heat-transferred object may be injected with thermal grease and other heat transfer materials. Adjuvant. As the heat transfer auxiliary agent, a liquid resin can be used, and a liquid thermosetting resin is preferably used. In addition, as a heat transfer auxiliary agent, a liquid rubber containing a thermally conductive filler may also be used. By injecting such a heat transfer auxiliary agent into the substrate 20, or between the substrate 20 and the heat-transferred object, the heat can be dissipated from the heat-transferred object more efficiently. Especially when the base material 20 contains a metal fiber non-woven fabric, the metal fiber non-woven fabric can also serve as a heat transfer auxiliary agent holder, and the base material 20 can hold the heat transfer auxiliary agent, so even if the heat transfer material expands and contracts, the heat transfer can be suppressed. The auxiliary agent leaks from the substrate 20 or between the substrate 20 and the heat-transferred object.

在傳熱體10的基材20被安裝於被傳熱物時，即使被傳熱物伸縮時，藉由基材20至少包含金屬纖維，可使該基材20具有柔軟性和對於被傳熱物的 追隨性，因此不易在基材20與被傳熱物之間產生間隙。因此，可維持充分的傳熱性。此外，由於一部分融接於基材20之金屬纖維之傳熱部30中的其他部分為露出，因此傳熱體10可獲得充分的傳熱效果。 When the base 20 of the heat transfer body 10 is mounted on the heat transfer object, even when the heat transfer object expands and contracts, the base 20 contains at least metal fibers, so that the base 20 can be flexible and resistant to the heat transfer. Material The followability makes it difficult to generate a gap between the substrate 20 and the object to be heated. Therefore, sufficient heat transfer properties can be maintained. In addition, since a part of the heat transfer portion 30 of the metal fiber fused to the base material 20 is exposed, the heat transfer body 10 can obtain a sufficient heat transfer effect.

接著使用圖6來說明藉由在供冷卻水或冷卻氣體等媒介物通過其中之導管的外周面安裝傳熱體10，而使用傳熱體10作為從周圍的環境將熱去除並予以冷卻之熱交換器的一部分的情形。如圖6所示，藉由融接、栓鎖、螺絲固定、接著劑等將傳熱體10的基材20安裝於被作為被傳熱物使用之導管40的外周面。此時，基材20係至少包含金屬纖維，因此可使基材20沿著導管之外周面的曲面而彎曲。因此，可抑制在基材20與導管40之間產生間隙。因此，可維持充分的傳熱性。此外，在將傳熱體10的基材20安裝於導管40的外周面時，於基材20之中或基材20與導管40之間，注入上述之導熱性油脂等傳熱輔助劑。藉此，即可效率更佳地從周圍的環境將熱去除而予以冷卻。 Next, Fig. 6 is used to explain that by installing a heat transfer body 10 on the outer peripheral surface of a pipe through which a medium such as cooling water or cooling gas passes, and using the heat transfer body 10 as the heat that removes heat from the surrounding environment and cools it The situation of part of the switch. As shown in FIG. 6, the base material 20 of the heat transfer body 10 is attached to the outer peripheral surface of the pipe 40 used as a heat transfer object by welding, latching, screw fixing, adhesive, etc. At this time, since the base material 20 contains at least metal fibers, the base material 20 can be bent along the curved surface of the outer peripheral surface of the catheter. Therefore, the generation of a gap between the base material 20 and the duct 40 can be suppressed. Therefore, sufficient heat transfer properties can be maintained. In addition, when the base 20 of the heat transfer body 10 is mounted on the outer peripheral surface of the duct 40, a heat transfer auxiliary agent such as the above-mentioned thermally conductive grease is injected into the base 20 or between the base 20 and the duct 40. Thereby, heat can be removed from the surrounding environment and cooled more efficiently.

為了從周圍的環境將熱去除並予以冷卻而在導管40安裝傳熱體10的基材20時，即使當導管40伸縮的情形下，亦可藉由基材20至少包含金屬纖維而使基材20具有柔軟性及對於被傳熱物的追隨性，因此不易在基材20與導管40之間產生間隙。因此，可維持充分的傳熱性。此外，在此情形下，一部分融接於基材20之金屬纖維之傳熱部30中的其他部分為露出，因此傳熱體10可獲得充分的傳熱效果。 When installing the base material 20 of the heat transfer body 10 in the duct 40 in order to remove heat from the surrounding environment and cool it down, even when the duct 40 expands and contracts, the base material 20 can be made by containing at least metal fibers. Since 20 has flexibility and followability with respect to the heat transfer object, it is difficult to generate a gap between the base material 20 and the duct 40. Therefore, sufficient heat transfer properties can be maintained. In addition, in this case, part of the heat transfer portion 30 of the metal fiber fused to the base material 20 is exposed, so the heat transfer body 10 can obtain a sufficient heat transfer effect.

另外，在本實施型態中，如圖6所示，係藉由將至少包含金屬纖維的基材20，一部分融接於基材20的金屬纖維且其他部分則露出的傳熱部30和供基材20安裝的被傳熱物(具體而言係導管40)予以組合而構成熱交換單元。此外， 在此種熱交換單元中，於基材20與被傳熱物之間或者在基材20中，包含有傳熱輔助劑。 In addition, in this embodiment, as shown in FIG. 6, a part of the base material 20 containing at least metal fibers is fused to the metal fibers of the base material 20 and the other parts are exposed to the heat transfer portion 30 and the supply The heat transfer objects (specifically, the duct 40) attached to the base 20 are combined to form a heat exchange unit. also, In such a heat exchange unit, a heat transfer auxiliary agent is included between the substrate 20 and the object to be heated or in the substrate 20.

另外，本實施型態之傳熱體或熱交換單元不限定於上述的態樣，亦可施加各種變更。 In addition, the heat transfer body or the heat exchange unit of this embodiment is not limited to the above-mentioned aspect, and various changes may be applied.

例如，並不限定於將傳熱部的各棒狀構件配置於網格線之各交點上者。作為其他態樣的傳熱體，亦可使用將傳熱部的各棒狀構件隨機地配置於基材上者。 For example, it is not limited to the one in which each rod-shaped member of a heat transfer part is arrange|positioned at each intersection of a mesh line. As a heat transfer body of another aspect, it is also possible to use the one in which each rod-shaped member of a heat transfer part is arrange|positioned at random on a base material.

此外，作為本實施型態之傳熱體，亦可使用圖7所示之構成者。圖7所示之傳熱體10a係具備有：平板狀的基材20，係要被安裝於被傳熱物；及傳熱部32，係由安裝於基材20的複數個板狀構件所構成。圖7所示之傳熱體10a中的基材20，係與圖1至圖6所示之傳熱體10中的基材20為大致相同的構成，故省略其說明。傳熱部32係具有從基材20朝外側延伸的複數個半狀構件，各板狀構件係配置成大致平行地延伸。此種各板狀構件係例如由金屬等所構成。更佳為構成基材20中所含之金屬纖維之金屬的種類和構成傳熱部32之各板狀構件之金屬的種類係相同。此時，藉由基材20及傳熱部32由相同種類的金屬所形成，可抑制在基材20與傳熱部32之間產生界面腐蝕。另外，本實施型態不限定於此種態樣。在其他態樣中，構成基材20中所含之金屬纖維之金屬的種類和構成傳熱部32之各板狀構件之金屬的種類亦可彼此不同。 In addition, as the heat transfer body of this embodiment, the structure shown in FIG. 7 can also be used. The heat transfer body 10a shown in FIG. 7 is provided with: a flat base material 20, which is to be mounted on a heat transfer object; and a heat transfer portion 32, which is formed by a plurality of plate-shaped members mounted on the base material 20 constitute.

Each of such plate-shaped members is made of metal or the like, for example. More preferably, the type of metal constituting the metal fiber contained in the base material 20 and the type of metal constituting each plate-shaped member of the heat transfer portion 32 are the same. At this time, since the base 20 and the heat transfer portion 32 are formed of the same type of metal, it is possible to suppress the occurrence of interfacial corrosion between the base 20 and the heat transfer portion 32. In addition, this embodiment is not limited to this aspect. In other aspects, the type of metal constituting the metal fiber contained in the base 20 and the type of metal constituting each plate-shaped member of the heat transfer portion 32 may be different from each other.

此外，構成傳熱部32的各板狀構件的一部分融接於基材20的金屬纖維，其他部分則露出。另外，構成傳熱部32之各板狀構件的端部，亦可在基材20的厚度方向上延伸至該基材20之途中的位置。或者，構成傳熱部32的各板狀構件，亦可貫通基材20。構成傳熱部32之各板狀構件的長度，較佳為1至50mm之範 圍內的大小，更佳為10mm至30mm之範圍內的大小。此外，構成傳熱部32之各板狀構件的厚度，較佳為0.1至5mm之範圍內的大小，更佳為0.5至3mm之範圍內的大小。 In addition, a part of each of the plate-shaped members constituting the heat transfer portion 32 is fused to the metal fiber of the base material 20, and other parts are exposed.

In addition, the thickness of each plate-shaped member constituting the heat transfer portion 32 is preferably a size in the range of 0.1 to 5 mm, and more preferably a size in the range of 0.5 to 3 mm.

當使用圖7所示之傳熱體10a時，亦與使用圖1至圖6所示之傳熱體10的情形同樣地，可藉由要被安裝於被傳熱物之基材20至少包含金屬纖維而使該基材20具有柔軟性及對於被傳熱物的追隨性，此外，由於一部分融接於基材20之金屬纖維之傳熱部32中之其他部分為露出，因此可獲得充分的傳熱效果。 When the heat transfer body 10a shown in FIG. 7 is used, it is also the same as the case of using the heat transfer body 10 shown in FIGS. The metal fiber makes the substrate 20 have flexibility and followability to the object to be heated. In addition, since a part of the metal fiber fused to the substrate 20 is exposed to other parts in the heat transfer portion 32, it is possible to obtain sufficient The heat transfer effect.

此外，作為再另一例，傳熱體的傳熱部亦可由棒狀構件或板狀構件以外之形狀的構件來形成。此外，傳熱部的材料不限定於金屬。 In addition, as yet another example, the heat transfer portion of the heat transfer body may be formed of a member having a shape other than a rod-shaped member or a plate-shaped member.
