[0049] The following refers to Figures 1-11 A plate heat exchanger 100 according to an embodiment of the present application is described.

[0050] As Figures 1-11 shown, the plate heat exchanger 100 according to an embodiment of the present application comprises a heat exchange body 10 and a flow guide pipe 20, the heat exchange body 10 defines a first channel 101 and a second channel 102, the first channel 101 is used to pass one kind of fluid, the second channel 102 is used to pass another kind of fluid, for example, one is refrigerant and the other is coolant, the refrigerant and the coolant exchange heat to achieve heat exchange; the flow guide pipe 20 cooperates with the heat exchange body 10, the flow guide pipe 20 comprises a pipe body 21 and a partition 22, at least a part of the partition 22 is arranged in the pipe body 21, the partition 22 can at least divide the pipe body 21 into a first inlet flow channel 201, a first outlet flow channel 202, a second inlet flow channel 203 and a second outlet flow channel 204, that is, under the partition of the partition 22, the pipe body 21 has at least four flow channels, including only four or more flow channels, for example, when the heat exchange body 10 defines two channels, the pipe body 21 can be divided into four flow channels; when the heat exchange body 10 defines three channels, the pipe body 21 can be divided into six flow channels.

[0051] Taking the pipe body 21 having four flow channels as an example, specifically, the pipe body 21 has a first inlet 211, a first outlet 212, a second inlet 213 and a second outlet 214, the first inlet 211 corresponds to the first inlet flow channel 201 and communicates, the first outlet 212 corresponds to the first outlet flow channel 202 and communicates, the second inlet 213 corresponds to the second inlet flow channel 203 and communicates, and the second outlet 214 corresponds to the second outlet flow channel 204 and communicates.

[0052] Among them, the first inlet flow channel 201 can communicate with the first channel 101 through the first inlet 211, and the first outlet flow channel 202 communicates with the first channel 101 through the first outlet 212, so that one kind of fluid can enter the flow guide pipe 20 through the first inlet flow channel 201, and then enter the first channel 101 through the first inlet 211, and then flow to the first outlet flow channel 202 through the first outlet 212, and finally flow out of the flow guide pipe 20 through the first outlet flow channel 202.

[0053] The second flow-in flow channel 203 can be communicated with the second channel 102 through a second inlet 213, and the second flow-out flow channel 204 can be communicated with the second channel 102 through a second outlet 214, so that another fluid can enter the flow guide pipe 20 through the second flow-in flow channel 203, enter the second channel 102 through the second inlet 213, flow to the second flow-out flow channel 204 through the second outlet 214, and finally flow out of the flow guide pipe 20 through the second flow-out flow channel 204.

[0054] That is, the flow guide pipe 20 can serve as a distributor of the plate heat exchanger 100, can make multiple fluids flow into multiple flow channels of the heat exchange body 10, and realize the distribution of the multiple fluids. Meanwhile, the flow guide pipe 20 can serve as an outlet of the plate heat exchanger 100, can make the fluids after heat exchange in the heat exchange body 10 flow out through the flow guide pipe 20, and realize the flow of the fluids. Therefore, multiple pipes for distributing fluids are not needed, only a joint connected with the flow guide pipe 20 is needed, the number of joints and pipes is reduced, and compared with the prior art in which multiple openings are arranged at multiple corners of the heat exchange body 10 to connect the pipes, the number of openings on the heat exchange body 10 is also reduced, so that the area available for heat exchange can be increased, the utilization rate of the heat exchange body 10 is improved, and the heat exchange efficiency is improved. In addition, because the area available for fluid flow on the heat exchange body 10 is increased, the distribution of the fluids on the heat exchange body 10 is more uniform, and the heat exchange efficiency is further improved.

[0055] According to the plate heat exchanger 100 of the embodiment of the present application, the flow guide pipe 20 having multiple flow channels is arranged, so that the flow guide pipe 20 can simultaneously enter and exit multiple fluids, thereby reducing the number of joints and pipes on the plate heat exchanger 100, simplifying the structure of the plate heat exchanger 100, reducing the manufacturing cost, and facilitating assembly. Meanwhile, the number of openings on the heat exchange body 10 can be reduced, so that the heat exchange area can be increased, the fluid flow is more uniform, and the heat exchange efficiency of the plate heat exchanger 100 is improved.

[0056] As shown in Figure 2 and Figure 3 In some embodiments, the partition 22 includes multiple partitions 221, each of which extends along the axial direction of the pipe body 21, and each flow channel is defined between two adjacent partitions 221, so that each flow channel extends along the axial direction of the pipe body 21, as shown in Figure 2 The first flow-in flow channel 201, the first flow-out flow channel 202, the second flow-in flow channel 203, and the second flow-out flow channel 204 respectively extend along the up-down direction, and the four flow channels are arranged in a circumferential direction, so that the flow capacity of each flow channel is increased, and the communication between each flow channel and the corresponding channel of the heat exchange body 10 is facilitated.

[0057] As shown in Figure 3As shown, in some examples, the inner side of each partition 221 is located in the middle of the tube body 21, and the inner sides of multiple partitions 221 are connected to each other, and the outer side of each partition 221 is connected to the inner wall surface of the tube body 21, thereby separating multiple flow channels in the tube body 21, and each flow channel is convenient for communicating with the opening on the tube body 21. Since multiple partitions 221 are connected to each other, the strength and stability of the partition 22 can be improved, thereby improving the strength and stability of the guide tube 20, and ensuring the distribution and diversion effects.

[0058] like Figure 3 As shown, in some specific examples, two adjacent partitions 221 are arranged vertically, so that the partition 22 can form a cross-shaped structure. When each partition 221 has the same size, the partition 22 can separate multiple flow channels of the same size.

[0059] It is understandable that by adjusting the structure of the separator 22 so as to change the size and shape of the flow channel, the pressure drop of the fluid can be changed to meet the needs of different working conditions, thereby achieving the purpose of reducing power, energy saving and consumption reduction.

[0060] like Figure 3 As shown, in some examples, two adjacent partitions 221 are connected by arc transition, thereby making the wall surface of the flow channel smooth, reducing friction, improving fluid flow efficiency, reducing resistance, etc.

[0061] like Figure 3 As shown, in some examples, the partition 221 is connected to the inner wall of the tube body 21 in a circular arc transition, thereby increasing the smoothness of the wall of the flow channel, reducing friction, improving fluid flow efficiency, reducing resistance, etc.

[0062] like Figure 4 and Figure 5 As shown, in some embodiments, the first inlet 211 and the first outlet 212 are spaced apart in the circumferential direction of the tube body 21 so as to communicate with the corresponding inlet flow channel and outlet flow channel; Figure 4 In the vertical direction shown in FIG5 , the first inlet 211 and the first outlet 212 are arranged alternately, so that the first inlet 211 and the first outlet 212 are located at different heights, thereby facilitating the inlet and outlet to be connected to different positions of the heat exchange body 10, facilitating the fluid to flow into a part of the first channel 101 and to flow out through another part of the first channel 101 after heat exchange, so as to achieve sufficient flow of the fluid, extend the flow path, improve the heat exchange effect, and avoid interference between the flow in and out processes.

[0063] like Figure 4 and Figure 5As shown, in some embodiments, the second inlet 213 and the second outlet 214 are spaced apart in the circumferential direction of the tube body 21 so as to communicate with the corresponding inlet flow channel and outlet flow channel; Figure 4 In the vertical direction shown in FIG, the second inlet 213 and the second outlet 214 are arranged alternately, so that the second inlet 213 and the second outlet 214 are located at different heights, thereby facilitating the inlet and the outlet to be connected to different positions of the heat exchange body 10, facilitating the fluid to flow into a part of the second channel 102 and to flow out through another part of the second channel 102 after heat exchange, so as to achieve sufficient flow of the fluid, extend the flow path, improve the heat exchange effect, and avoid interference between the flow in and out processes.

[0064] like Figure 2 、 Figure 4 and Figure 5 As shown, in some embodiments, the first inlet 211, the second inlet 213, the first outlet 212 and the second outlet 214 are arranged along a spiral line in the circumferential direction of the tube body 21, that is, along Figure 4 and Figure 5 In the clockwise direction indicated by the middle arrow, the second inlet 213 is located on the front upper side of the first inlet 211, the first outlet 212 is located on the front upper side of the second inlet 213, and the second outlet 214 is located on the front upper side of the first outlet 212. Thus, in the circumferential direction of the tube body 21, the first inlet 211, the second inlet 213, the first outlet 212 and the second outlet 214 are arranged at intervals. In the axial direction of the tube body 21 (as shown in FIG. Figure 4 In the up-down direction shown in the figure, the first inlet 211, the second inlet 213, the first outlet 212 and the second outlet 214 are spaced apart and staggered, that is, in the axial direction of the tube body 21, they are arranged in a cycle in the form of the first inlet 211, the second inlet 213, the first outlet 212, the second outlet 214, the first inlet 211, the second inlet 213, the first outlet 212 and the second outlet 214.

[0065] Thus, the multiple openings on the tube body 21 can be located at different heights, which facilitates the fluid to flow into the first channel 101 and the second channel 102 and avoids interference. At the same time, it facilitates the fluid to flow fully, extends the flow path, and improves the heat exchange effect.

[0066] In some embodiments, the shapes of the four openings may be the same or different, and the shape of each opening includes at least one of square, circle, oblong, and ellipse.

[0067] It can be understood that by changing the shape of the opening on the pipe body 21, the pressure drop of the fluid can be changed to meet the needs of different working conditions, achieving the purpose of reducing power, saving energy and reducing consumption; at the same time, in the working condition of phase change of the heat exchange fluid, the opening size is changed according to the needs, that is, the fluid distribution condition can be improved, and the uneven distribution of gas and liquid between the flow channels of the heat exchange body 10 is solved.

[0068] As shown in Figure 1 In some embodiments, the heat exchange body 10 includes a plurality of heat exchange plates 11, and the plurality of heat exchange plates 11 are arranged in a stacked manner, and the stacking direction is substantially the same as the axial direction of the pipe body 21. The plate channels formed between adjacent two heat exchange plates 11 are part of the first channel 101 or the second channel 102, and the adjacent two heat exchange plates 11 have corresponding inlets or outlets to communicate with the corresponding flow channels, that is, in the arrangement direction of the plurality of heat exchange plates 11, the first inlet 211 is located between adjacent two heat exchange plates 11, the first outlet 212 is located between other adjacent two heat exchange plates 11, the second inlet 213 is located between other adjacent two heat exchange plates 11, and the second outlet 214 is located between other adjacent two heat exchange plates 11.

[0069] Specifically, the four openings of the first inlet 211, the second inlet 213, the first outlet 212 and the second outlet 214 are arranged along a spiral line in the circumferential direction of the pipe body 21, each opening can communicate with a plate channel, and adjacent plate channels communicate with different openings respectively, thereby connecting different flow channels on the flow guide pipe 20, thereby ensuring that different fluids flow in adjacent plate channels, that is, different fluids flow on both sides of a heat exchange plate 11, and the heat exchange function is realized.

[0070] As shown in Figure 1 In some embodiments, the heat exchange body 10 has a mounting through hole 103, the mounting through hole 103 penetrates the plurality of heat exchange plates 11, the flow guide pipe 20 is inserted into the mounting through hole 103, and the outer periphery of the flow guide pipe 20 cooperates with the heat exchange body 10, thereby facilitating the flow channels of the flow guide pipe 20 to communicate with the channels of the heat exchange body 10, and easy to realize sealing, and at the same time, the structure of the entire plate heat exchanger 100 is more compact.

[0071] The mounting through hole 103 can be located at the corner of the heat exchange body 10 or at the middle of the heat exchange body 10. Since the heat exchange body 10 only needs to be provided with one mounting through hole 103, the position of the mounting through hole 103 does not need to be limited too much.

[0072] In other embodiments, the flow guide tube 20 can also be installed on the outside of the heat exchange body 10. The outer periphery of the heat exchange body 10 has multiple openings connected to the channel. The multiple openings on the flow guide tube 20 correspond to the multiple openings, that is, the flow guide tube 20 does not need to be inserted into the heat exchange body 10, thereby reducing the occupation of the internal space of the heat exchange body 10.

[0073] like Figures 6-11 As shown, in some specific embodiments, the multiple heat exchange plates 11 include a first heat exchange plate 121, a second heat exchange plate 122, a third heat exchange plate 123 and a fourth heat exchange plate 124 arranged in sequence, that is, along the stacking direction of the multiple heat exchange plates 11, the first heat exchange plate 121, the second heat exchange plate 122, the third heat exchange plate 123, the fourth heat exchange plate 124, the first heat exchange plate 121, the second heat exchange plate 122, the third heat exchange plate 123, the fourth heat exchange plate 124 and so on.

[0074] like Figure 10 and Figure 11 As shown, a portion of the first channel 101 (i.e., the first plate channel 11a) is defined between the first heat exchange plate 121 and the second heat exchange plate 122, and a portion of the first channel 101 (i.e., the second plate channel 11b) is defined between the third heat exchange plate 123 and the fourth heat exchange plate 124. The second heat exchange plate 122 and the third heat exchange plate 123 cooperate with each other, and a first connecting port 15 is formed at the cooperation position, so that a portion of the first channel 101 (the first plate channel 11a) is connected to a portion of the first channel 101 (the second plate channel 11b) through the first connecting port 15.

[0075] like Figure 8 and Figure 9 As shown, a portion of the second channel 102 (i.e., the third plate channel 11c) is defined between the first heat exchange plate 121 and the adjacent fourth heat exchange plate 124 (not shown in the figure), and a portion of the second channel 102 (i.e., the fourth plate channel 11d) is defined between the second heat exchange plate 122 and the third heat exchange plate 123. The first heat exchange plate 121 and the second heat exchange plate 122 are matched, and a second connecting port 16 is formed at the matching position. A portion of the second channel 102 (the third plate channel 11c) is connected to a portion of the second channel 102 (the fourth plate channel 11d) through the second connecting port 16.

[0076] It can be understood that after the second heat exchange plate 122 and the third heat exchange plate 123 are matched in place, the second heat exchange plate 122 and the third heat exchange plate 123 are sealingly matched around the first communication port 15, so that the second passage 102 between the second heat exchange plate 122 and the third heat exchange plate 123 is not communicated with the first passage 101 through the first communication port 15, and the first communication port 15 is only used to communicate each part of the plurality of first passages 101. Thus, under the cooperation of the two adjacent heat exchange plates 11, the plurality of parts of the first passage 101 can be communicated with each other through the first communication port 15.

[0077] Correspondingly, after the first heat exchange plate 121 and the second heat exchange plate 122 are matched in place, the first heat exchange plate 121 and the second heat exchange plate 122 are sealingly matched around the second communication port 16, so that the first passage 101 between the first heat exchange plate 121 and the second heat exchange plate 122 is not communicated with the second passage 102 through the second communication port 16, and the second communication port 16 is only used to communicate each part of the plurality of second passages 102.

[0078] Of course, as Figure 9 shown, the third heat exchange plate 123 and the fourth heat exchange plate 124 are also sealingly matched and define a second communication port 16, so that a part of the second passage 102 above the third heat exchange plate 123 is communicated with a part of the second passage 102 below the fourth heat exchange plate 124, that is, under the cooperation of the two adjacent heat exchange plates 11, the plurality of parts of the second passage 102 can be communicated with each other through the second communication port 16.

[0079] It should be noted that although the plurality of parts (plate channels) of the first passage 101 are communicated with each other, and the plurality of parts (plate channels) of the second passage 102 are communicated with each other, since each plate channel corresponds to an inlet or an outlet, under the action of pressure, usually one of the two adjacent plate channels of each passage is used for flowing in, and the other is used for flowing out.

[0080] As shown in Figure 6 and Figure 7 in some specific embodiments, the projections of the first communication port 15 and the second communication port 16 on the plane where any heat exchange plate 11 is located do not coincide, so that the first communication port 15 and the second communication port 16 do not overlap, avoiding the communication of the first passage 101 and the second passage 102.

[0081] As shown in Figure 6 , the first communication port 15 and the second communication port 16 are arranged on the side of the heat exchange body 10 away from the flow guide pipe 20, so that the flow path can be lengthened and the heat exchange effect can be improved.

[0083] As shown in the drawings, Figure 11 in some embodiments, the bottom wall of the first recess 141 has a first blocking ring 1411 extending towards the second side 10b, the middle part of the first protrusion 131 has a first avoiding hole, the first blocking ring 1411 is inserted and matched with the first avoiding hole, the middle part of the first blocking ring 1411 defines the first communication port 15, on the one hand, the first blocking ring 1411 is inserted and matched with the first avoiding hole, which can not only play a positioning foolproof role in the assembly of the two heat exchange plates 11, but also be conducive to improving the reliability of the cooperation of the two heat exchange plates 11, and is also convenient for sealing the outer periphery of the first communication port 15 of the two heat exchange plates 11, for example, through interference fit of the first blocking ring 1411 and the first avoiding hole, or setting a sealing ring on the outer periphery of the first blocking ring 1411 and sealing fit with the first avoiding hole, or welding the edge of the first blocking ring 1411 and the first avoiding hole, which can conveniently and effectively realize the sealing of the place.

On the one hand, the insertion of the second blocking ring 1321 into the second avoiding hole can not only prevent the assembly of the two heat exchange plates 11 from being mistaken, but also improve the reliability of the cooperation of the two heat exchange plates 11, and facilitate the sealing of the two heat exchange plates 11 at the outer periphery of the second communication port 16, for example, by interference fit of the second blocking ring 1321 and the second avoiding hole, or by setting a sealing ring on the outer periphery of the second blocking ring 1321 and sealing fit with the second avoiding hole, or by welding the edge of the second blocking ring 1321 and the second avoiding hole, which can facilitate and effectively realize the sealing at this place.
