The specific embodiment
Core of the present utility model is for providing a kind of heat exchanger, and this heat exchanger can reduce wind field and non-uniform temperature and on the impact that distribution of refrigerant causes, make cold-producing medium be in uniform state.
In order to make those skilled in the art understand better the technical solution of the utility model, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 2 and Fig. 3, Fig. 2 provides the structural representation of a kind of specific embodiment of heat exchanger for the utility model; Fig. 3 is the structural representation that inserts the heat exchanger tube row of current-sharing header among Fig. 2.
The heat exchanger 2 that this specific embodiment provides, has total heat exchanger tube row 21, and be positioned at total heat exchanger tube and arrange first header 22 at 21 two ends and the second header 23, the first headers 22 and the second header 23 respectively as inlet tube and outlet, or outlet and inlet tube; Always heat exchanger tube row 21 is bent to form at least two row's heat exchanger tubes rows, and each heat exchanger tube is arranged almost parallel, also is set up in parallel compactly, namely forms collapsible heat exchanger 2, and the space that this kind heat exchanger 2 occupies is less.Heat exchanger 2 shown in Figure 2 has three row heat exchanger tubes rows, certainly, can determine according to the factors such as size, cost control that actual heat exchange demand, heat exchanger 2 arrange the space heat exchanger tube row's concrete number.
Unlike the prior art be that at least one row's heat exchanger tube row of heat exchanger 2 is provided with current-sharing header 24.Heat exchanger tube row's middle part in the middle of current-sharing header 24 among Fig. 2 is inserted in, the first header 22 is during as entrance point, cold-producing medium (cold-producing medium) flows into the first heat pipe row 211 from the first header 22, then the second heat pipe row 212 in the middle of entering, when reaching the second heat pipe row 212 middle part, converge in the current-sharing header 24, again all disposed by current-sharing header 24 in the second heat pipe row 212 the downstream heat exchanger tube, then flow to the 3rd heat pipe row 213, finally flow out from the second header 23.The second header 23 is during as entrance point, and flow path and the foregoing of cold-producing medium are just the opposite.
When blower fan is located at a side of heat exchanger 2 among Fig. 2, blower fan obviously has larger wind speed over against heat exchanger 2 parts of position, when placing the middle part in Fig. 2 heat exchanger 2 left sides such as heat exchanger 2, the wind speed in heat exchanger 2 stage casings is obviously greater than the left section wind speed with right section among Fig. 3, then the refrigerant flow of left section and right section is less than the refrigerant flow in stage casing (in the foregoing, left and right accompanying drawing take correspondence is as the visual angle).Cold-producing medium pockety is flowed through behind the current-sharing header 24, cold-producing medium is mixed and is reassigned to the heat exchanger tube row in current-sharing header 24 downstreams, thereby reduced the inhomogeneous impact of the inhomogeneous cold-producing medium that causes of wind speed, thereby, exchange capability of heat that can balanced heat exchanger 2 improves heat exchange efficiency.
Current-sharing header 24 is inserted in the second heat pipe row 212 middle part among Fig. 2, in fact, also can be inserted in the first heat pipe row the 211 or the 3rd heat pipe row 213, or is inserted in heat exchanger tube row's top or bottom.When being inserted in the second heat pipe row 212 middle part, cold-producing medium flow through current-sharing header 24 the front and back stroke about equally, the effect of uniform cold-producing medium is comparatively obvious, and cold-producing medium enters from the first header 22 or the second header 23, all has identical current-sharing effect.Certainly, during design, can be according to the actual requirements the heat exchanger tube ranking of the height of current-sharing header 24 and setting be put and appropriately adjust, so that cold-producing medium locates to mix reallocation in place.
Please refer to Fig. 4, Fig. 4 provides the structural representation of heat exchanger the second specific embodiment for the utility model.
The axial length of current-sharing header 24 is less than the heat exchanger tube of correspondence row's transverse width in this specific embodiment, and current-sharing header 24 can be inserted in left section of corresponding heat exchanger tube row, stage casing or right section (take Fig. 4 as the visual angle).In the first specific embodiment, mention because the air quantity wind speed profile is inhomogeneous, left section of heat exchanger 2, stage casing and right section cold-producing medium each other do not wait, cause whole distribution of refrigerant inhomogeneous, in fact, left section of heat exchanger 2, stage casing and right section zone separately also may produce the inhomogeneous phenomenon of distribution of refrigerant, and namely heat exchanger tube comes in the subrange and also may have inhomogeneous phenomenon.The axial length of current-sharing header 24 can insert current-sharing header 24 at heat exchanger tube row's regional area during less than heat exchanger tube row's axial length, realize more targetedly the uniform of cold-producing medium.
Among Fig. 4, row has inserted three current-sharing headers 24 at heat exchanger tube, and then left section of heat exchanger 2, stage casing and right section can carry out separately mixing and the reallocation of cold-producing medium.Wherein, adjacent two current-sharing headers 24 transversely also have an overlapping part heat exchanger tube row's, and the cold-producing medium of lap also can mix and reallocate, further improves the uniformity that cold-producing medium is reallocated, at this moment, adjacent current-sharing header 24 axially staggering heat exchanger tube row.
Please refer to Fig. 5, Fig. 5 provides the structural representation of the third specific embodiment of heat exchanger for the utility model.
In this specific embodiment, current-sharing header 24 and the first header 22 or the second header 23 have angle, and as shown in Figure 5, current-sharing header 24 is obliquely installed, and its left section is higher than right section.Because air quantity skewness, if the distribution of refrigerant that heat exchanger is 2 left sections is more, right section distribution of refrigerant is less, then be obliquely installed owing to current-sharing header 24, cold-producing medium can be inclined to lower right section owing to Action of Gravity Field in current-sharing header 24, then right section distribution of refrigerant can increase, and the skewness between each heat exchanger tube can be owing to mixing the balance that becomes of reallocating simultaneously.Based on this principle, current-sharing header 24 is not limited to the structure shown in Fig. 5, such as, current-sharing header 24 can be comprised of two sections headers, V-shaped or inverted V-shaped, correspondingly, two sections cold-producing medium can flow to the stage casing about heat exchanger tube row, or about the refrigerant flow direction in stage casing two sections, increase the stage casing or about two sections distribution of refrigerant; Certainly, also can be only in left section, stage casing or the right section current-sharing header 24 that inclination is set.Namely according to Action of Gravity Field and the inhomogeneous actual conditions of distribution of refrigerant, the structure of design current-sharing header 24 makes current-sharing header 24 tend to the less position of cold-producing medium from the more position of cold-producing medium.
Please refer to Fig. 6, Fig. 6 is the structural representation of the 4th kind of specific embodiment of heat exchanger that the utility model provides.
In this specific embodiment, the adapter 25 of flowing out or flowing into for cold-producing medium is set at current-sharing header 24.When taking over 25 when using as inlet tube, the first header 22 and the second header 23 all use as outlet, and cold-producing medium enters current-sharing header 24 from taking over 25, again from the first header 22 and 23 outflows of the second header; Take over 25 when using as outlet, flow path is just the opposite.After adapter 25 then was set, simultaneously heat exchange of the heat exchanger tube at current-sharing header 24 two ends row was during refrigerant flow direction current-sharing header 24 place, directly flow out, skewness can not aggravate owing to the prolongation of stroke, and cold-producing medium flows into from header, has same beneficial effect yet; Certainly, this structure still can keep the heat exchange efficiency of heat exchanger 2, i.e. simultaneously heat exchange of the heat exchanger tube at current-sharing header 24 two ends row.Therefore, the heat exchanger 2 of this structure can keep heat exchange efficiency when reducing the inhomogeneous impact of distribution of refrigerant.And, close the adapter 25 on the current-sharing header 24 after, heat exchanger 2 can be used according to above-mentioned arbitrary embodiment.
Please refer to Fig. 7, Fig. 7 is the structural representation of the 5th kind of specific embodiment of heat exchanger that the utility model provides.
In this specific embodiment, current-sharing header 24 comprises two headers that are set up in parallel and are connected, and the opposing side of two headers all arranges the slotted eye that is communicated with each corresponding heat exchanger tube.As shown in Figure 7, the upper header of current-sharing header 24 is offered slotted eye at upper surface, heat exchanger tube for heat exchanger tube row the first half inserts, lower header is offered slotted eye at lower surface, heat exchanger tube for heat exchanger tube row the latter half inserts, and is communicated with between upper header and the lower header, forms current-sharing header 24, connectivity structure between two headers is comparatively simple, and tube connector 241 can be set between upper header and lower header.Therefore, the current-sharing header 24 of this structure adds man-hour, and one-sided fluting on two headers can reduce difficulty of processing and the input that reduces equipment.
Fig. 2 is to heat exchanger 2 shown in Figure 6, and total heat exchanger tube of all serving as reasons is arranged 21 serpentine heat exchangers 22 that are bent to form for twice according to clockwise and counterclockwise order circularly.Total heat exchanger tube row 21 is bent to form three row's heat exchanger tube rows according to clockwise, counterclockwise order among Fig. 2, continues the circulation bending, can form four rows, five rows, six rows, or the above heat exchanger tube row of six rows.The heat exchanger 22 that this kind bending mode forms, its bending operation is comparatively simple.
Please refer to Fig. 8, Fig. 8 is the structural representation of the 6th kind of specific embodiment of heat exchanger that the utility model provides.
According to clockwise or counterclockwise be bent to form, i.e. all the time in the same direction bending forms the heat exchanger 2 of Cyclotron by total heat exchanger tube for 2 on heat exchanger among Fig. 8, and the heat exchanger tube row of formation is gradually to internal bend.This kind bending operation is also comparatively simple, is convenient to implement.Current-sharing header 24 places the 3rd heat exchanger tube row 213 middle part, can certainly place the first heat exchanger tube row the 211 or second heat exchanger tube row 212.
Please refer to Fig. 9, Fig. 9 is the structural representation of the 7th kind of specific embodiment of heat exchanger that the utility model provides.
In this specific embodiment, heat exchanger 2 is bent to form according to clockwise, counterclockwise, counterclockwise, clockwise direction by total heat exchanger tube row 21, and current-sharing header 24 is placed the 3rd heat pipe row's 213 who is bent to form middle part.This kind bending mode can be adjusted the relative position of the first header 22 and the second header 23 more neatly, and two headers can be positioned at homonymy among Fig. 9, to adapt to corresponding installation environment.
For above-described embodiment, on the short transverse of heat exchanger 2, can make heat exchanger tube row corresponding to heat exchange position, at least two places horizontal row different, laterally be the direction perpendicular to each heat exchanger tube row surface.Can describe with reference to the structure of following Figure 10 to Figure 18.
Please refer to Figure 10 to Figure 12, Figure 10 is the first distressed structure of Fig. 2 and the structural representation of blower fan combination; Figure 11 is the second distressed structure of Fig. 2 and the structural representation of blower fan combination; Figure 12 is the structural representation of the third distressed structure and blower fan combination among Fig. 2.
Figure 10 is located in heat exchanger 2 frameworks 3 to heat exchanger 2 shown in Figure 12, and blower fan 4 is located at a side opposing with inlet side usually, is located at heat exchanger 2 first heat exchanger tubes among Figure 10 to Figure 12 and arranges the first header 22 of 211 ends and be entrance point.Take Figure 10 as example, this heat exchanger that illustrates 2 can be divided into up and down two parts on short transverse, the heat exchanger tube row's that top is corresponding horizontal row is two rows, the heat exchanger tube row's that the bottom is corresponding horizontal row is three rows (following content degradation is described as " corresponding heat exchanger tube row "), and the 3rd heat exchanger tube row 213 who namely is bent to form highly is lower than the first heat exchanger tube row the 211 and second heat exchanger tube row 212 height.
Operating mode when the structure of this embodiment is applicable to blower fan 4 and places heat exchanger 2 bottom, at this moment, air quantity and the wind speed of bottom wind field are larger, penetration power along heat exchanger 2 thickness directions is stronger, then each heat exchanger tube of bottom is arranged the air quantity that all can obtain to suit, therefore, the bottom exchange capability of heat is stronger, and more heat exchanger tube row can be set; Correspondingly, air quantity and the wind speed of top wind field are less, and exchange capability of heat is lower, and in order to realize the equilibrium of heat exchanger 2 upper and lower exchange capability of heat, heat exchanger tube row corresponding to top wind field is relatively less than the heat exchanger tube row of bottom.
The exchange capability of heat that then 2 structures of the heat exchanger among Figure 10 can balanced heat exchanger 2 improves heat exchange efficiency.The description of above-mentioned principle combines blower fan 4, in fact, also can judge according to the frosting situation (rule of thumb or experiment draw the more and less position of frosting), the position that exchange capability of heat is weak, the easy frosting of cold-producing medium, so should improve the more multipoint exchange capability of heat of switching heat-exchanger 2 frostings, reduce heat exchanger tube row corresponding to this position, Figure 10 is the situation of the corresponding heat exchanger easy frosting in 2 tops then.Namely on the short transverse of heat exchanger 2, weak or more heat exchanger tube row corresponding to position of frosting of wind field should be less, strong or less heat exchanger tube row corresponding to position of frosting of wind field should be more, in frosting in the situation that the leading portion of refrigerant flow path progressively develops, the leading portion of refrigerant flow path is located at the less position of heat exchanger tube row, can effectively prolong heat pamp, the stream back segment is located at the more position of heat exchanger tube row, can strengthen the heat exchange area of frostless section of stream back segment, thereby refrigerant flow path can get the maximum optimization from heat exchange and frosting aspect.Be simplified characterization, related embodiment only describes in conjunction with heat exchanger 2 structures with the installation site of blower fan 4 in the literary composition, no longer mentions the frosting situation.
In addition, need to prove that the height described in the literary composition refers to, when heat exchanger tube row vertically places (cold-producing medium vertically flows), the height of its vertical direction.
Then because on the short transverse of heat exchanger, the heat exchanger tube row's that heat exchange position, at least two places is corresponding number is different, then blower fan 4 can be installed on the relatively many positions of corresponding heat exchanger tube row, the larger wind field of the corresponding wind speed air quantity in position that heat exchanger tube row order is more, the less wind field of the corresponding wind speed air quantity in position that heat exchanger tube row order is less, thereby make the layout of heat exchanger tube row in the heat exchanger 2 adapt to corresponding working environment, have balanced heat exchanger 2 exchange capability of heat, improve the advantage of heat exchanger 2 heat exchange efficiencies.Then in fact, the heat exchanger 2 of this kind structure not only can reach uniform cold-producing medium on width, improves the purpose of heat exchange efficiency, and the architecture advances on heat exchanger 2 short transverses can improve heat exchange efficiency equally.
In like manner, among Figure 11, heat exchanger 2 structures to Fig. 2 are made certain distortion, heat exchanger 2 can be divided into the upper, middle and lower, the heat exchanger tube row order that medium position is corresponding is three rows, top, the heat exchanger tube row order that lower position is corresponding are two rows, and the first heat exchanger tube row the 211 and the 3rd heat exchanger tube row's 213 who namely forms height is all arranged 212 height less than middle the second heat exchanger tube.This structure is applicable to the operating mode that blower fan 4 places heat exchanger 2 near middles, then air quantity and the wind speed of the corresponding wind field in heat exchanger 2 upper and lowers are less, exchange capability of heat is lower, and the air quantity of middle part wind field and wind speed are larger, exchange capability of heat is higher, and therefore, heat exchanger tube row corresponding to middle part wind field is greater than the heat exchanger tube row of upper and lower, play equally the exchange capability of heat of balanced heat exchanger 2, improve the effect of heat exchange efficiency.
Above-described embodiment is on short transverse, heat exchanger 2 is divided into top, bottom, or top, middle part, bottom, in fact, according to number and the installation site of blower fan 4, further segmentation and distortion, such as, be divided into four parts under certainly going up, first and heat exchanger tube row corresponding to third part more than the second and the 4th part heat exchanger tube row's number, then can in first and third part blower fan 4 is set respectively, can realize the purpose of this utility model equally.Therefore, can also design the heat exchanger 2 of other structures, make heat exchanger tube row corresponding to heat exchange position, at least two places on its short transverse different.Hence one can see that, and the purpose that need to reach is: at the height and position place of the heat exchanger 2 of blower fan 4 correspondences, corresponding heat exchanger tube row is more than heat exchanger tube row corresponding to other positions, or, blower fan 4 is installed on the relatively many positions of corresponding heat exchanger tube row.Namely in fact, this embodiment is to change according to the exchange capability of heat of heat exchanger 2 different pieces different heat exchanger tube rows is set.
Please refer to Figure 13, Figure 13 is the first distressed structure schematic diagram of Fig. 8.
The first heat exchanger tube row the 211 and second heat exchanger tube row's 212 of the heat exchanger 2 of this embodiment height is all arranged 213 height greater than the 3rd heat exchanger tube of centre, Figure 13 is applicable to the operating mode that blower fan 4 is positioned at the bottom, the heat exchanger 2 of Figure 13 is inverted, namely applicable to blower fan 4 superposed operating modes, certainly, by distortion, can also form heat exchanger tube row corresponding to medium position more than the structure of upper and lower.The bending operation of this embodiment is also comparatively simple.
