[0019] The present application will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] Combine Figures 1-9, illustrating a first embodiment of a heat exchanger 100. Heat exchanger 100 includes a housing 1' having a housing cavity 101. In this embodiment, housing 1' comprises a first housing 1 and a second housing 2, which are fixedly connected by welding, clamping, or other methods. Heat exchanger 100 includes a fifth seal 65, which is generally annular and located between first and second housings 1, 2. The seal between the first and second housings 1, 2 is enhanced by the fifth seal 65, improving the sealing performance of heat exchanger 100.

[0021] Combine Figure 2 、 Figure 5-Figure 6 The heat exchanger 100 includes a heat exchange core 3, which is assembled into a housing chamber 101. Due to the need for space for the heat exchange core 3, a certain gap exists between the heat exchange core 3 and the inner circumferential wall forming the housing chamber 101. The heat exchange core 3 includes a first heat exchange portion a and a second heat exchange portion b. The first heat exchange portion a includes a plurality of first flat tubes 31 and a plurality of first fins 33. The plurality of first flat tubes 31 are staggered along the height of the heat exchanger 100, with first fins 33 located between adjacent first flat tubes 31. The second heat exchange portion b includes a plurality of second flat tubes 32 and a plurality of second fins 34. The plurality of second flat tubes 32 are staggered along the height of the heat exchanger 100, with second fins 34 located between adjacent second flat tubes 32.

[0022] Combine Figure 1-Figure 2 、 Figure 5-Figure 7 Along the length of the heat exchanger 100, the heat exchanger 100 includes a first end 8 and a second end 9. The heat exchange core 3 includes a first header assembly 36 and a second header assembly 37. The first header assembly 36 is located near the second end 9 of the heat exchanger 100, and the second header assembly 37 is located near the first end 8 of the heat exchanger 100. The heat exchange core 3 also includes a deflector plate 35, which is located between the first header assembly 36 and the second header assembly 37. One end of the deflector plate 35 is fixedly connected to the first header assembly 36, and the other end of the deflector plate 35 is fixedly connected to the second header assembly 37. The connection method includes welding, clamping, etc. Along the width of the heat exchanger 100, the first heat exchange portion a and the second heat exchange portion b are located on either side of the deflector plate 35, and the two sides of the deflector plate 35 respectively abut the first heat exchange portion a and the second heat exchange portion b.

[0023] Combine Figure 5-Figure 7In this embodiment, the deflector plate 35 includes a partition 351 and a flow-through portion 352. The partition 351 is closer to the second header assembly 37 than the flow-through portion 352, while the flow-through portion 352 is closer to the first header assembly 36 than the partition 351. The partition 351 is generally plate-shaped and separates the first heat exchange section a from the second heat exchange section b. Specifically, the partition 351 separates the first fins 33 and the second fins 34 on either side, preventing the first fluid from flowing between the partition 351 and the flow-through portion 352. The flow-through portion 352 includes a plurality of flow holes 3521, through which the first fluid flows from the first fins 33 to the second fins 34. The provision of the deflector plate 35 can extend the path of the first fluid and improve heat exchange.

[0024] Combine Figure 1-Figure 2 、 Figure 5-Figure 7 , Figure 2 The thick solid line indicates a flow path of the first fluid, and the thin solid line indicates a flow path of the second fluid. Heat exchanger 100 includes a first inlet 4 and a first outlet 5. The first fluid flows into heat exchanger 100 from the cavity of first inlet 4 and flows out of heat exchanger 100 from the cavity of first outlet 5. Heat exchanger 100 includes a first inlet flow channel 16 and a first outlet flow channel 17. The walls forming first inlet flow channel 16 include the walls of first shell 1 and heat exchange core 3, and the walls forming first outlet flow channel 17 include the walls of first shell 1 and heat exchange core 3. The cavity of first inlet 4 and first inlet flow channel 16 are aligned and connected along the height direction of heat exchanger 100. The cavity of first outlet 5 and first outlet flow channel 17 are aligned and connected along the height direction of heat exchanger 100.

[0025] In this embodiment, the first inlet flow channel 16 and the first outlet flow channel 17 are located at the first end 8 of the heat exchanger 100. Both the first inlet flow channel 16 and the first outlet flow channel 17 are located on the right side of the heat exchange core 3. Along the width of the heat exchanger 100, the first inlet flow channel 16 and the first outlet flow channel 17 are located on both sides of the heat exchanger 100. Along the height of the heat exchanger 100, the first inlet portion 4 and the first outlet portion 5 are located on the same side of the heat exchanger 100. In this embodiment, the first inlet portion 4 and the first outlet portion 5 are located on the upper side of the heat exchanger. The first fluid flows from the cavity of the first inlet portion 4 into the first inlet channel 16, then flows from the first inlet channel 16 through the gap between the heat exchange core 3 and the wall forming the accommodating cavity 101 into the first window 331 of the first fin 33. Blocked by the partition 351, the first fluid flows from the end of the first fin 33 near the second header assembly 37 to the end of the first fin 33 near the first header assembly 36. Passing through the flow holes 3521 of the flow portion 352, the first fluid flows to the second window 341 of the second fin 34, then flows from the first outlet channel 17 to the cavity of the first outlet portion 5, and exits the heat exchanger 100 from the cavity of the first outlet portion 5. The configuration of the deflector 35 causes the first fluid to flow in a U-loop.

[0026] In other embodiments, the deflector plate 35 may not be provided with the flow-through portion 352. One end of the partition 351 may be fixedly connected to the second header assembly 37, and a gap may be provided between the other end of the partition 351 and the first header assembly 36 along the length of the heat exchanger 100. This can also achieve a U-loop flow of the first fluid. In this embodiment, the first fins 33 and the second fins 34 may be integral or separate.

[0027] In other embodiments, along the height direction of the heat exchanger 100, the first inlet 4 and the first outlet 5 may also be located on both sides of the height direction of the heat exchanger 100, for example, the first inlet 4 is located above the first shell 1, and the first outlet 5 is located below the first shell 1.

[0028] In other embodiments, the first inlet channel 16 and the first outlet channel 17 may also be disposed on both sides of the length direction of the heat exchanger 100, or may be disposed diagonally. The positions of the first inlet portion 4 and the first outlet portion 5 may be set as needed.

[0029] Combine Figure 1-Figure 2 、 Figure 5-Figure 7 , the heat exchanger 100 includes a second inlet 102 and a second outlet 103, and the second inlet 102 and the second outlet 103 are located at the second end 9 of the heat exchanger 100. The second fluid flows into the first manifold assembly 36 from the second inlet 102, flows to the second manifold assembly 37 through the first flat tube 31, flows from the second manifold assembly 37 to the second flat tube 32 assembly, flows from the second flat tube 32 assembly to the first manifold assembly 36, and then flows out of the heat exchanger 100 from the second outlet 103. The first fluid and the second fluid exchange heat in the heat exchanger 100. The first fluid can be a coolant, such as cooling water, etc., and the second fluid can be a refrigerant, such as R744, etc. The flow path of the second fluid is not limited to the description of this embodiment. In other embodiments, the heat exchange core 3 can adopt any structure such as single-flow, multi-flow, single-row flat tube, multi-row flat tube, etc. For the convenience of description, the upper and lower directions are defined as those in the attached drawings of the specification. Figure 1 The up and down directions of the heat exchanger 100 are defined as the height direction of the heat exchanger 100 in the accompanying drawings. Figure 1 height direction.

[0030] Combine Figure 2 and Figure 3The heat exchange core 3 abuts the second shell 2. The heat exchanger 100 includes a first seal 61, which is located between the inner circumferential wall forming the accommodating cavity 101 and the heat exchange core 3. The first seal 61 can prevent the first fluid from flowing from the first inlet flow channel 16 along the gap between the heat exchange core 3 and the inner circumferential wall forming the accommodating cavity 101 to the first outlet flow channel 17. There is a gap between the heat exchange core 3 and the inner circumferential wall forming the accommodating cavity 101. The provision of the first seal 61 is conducive to improving the situation in which the first fluid flows into the heat exchanger 100 from the first inlet flow channel 16 and then flows out of the heat exchanger 100 directly from the first outlet flow channel 17 through the gap between the heat exchange core 3 and the inner circumferential wall forming the accommodating cavity 101, thereby increasing the flow rate of the first fluid participating in the heat exchange with the second fluid, allowing more of the first fluid to participate in the heat exchange with the second fluid, and improving the heat exchange effect of the heat exchanger 100.

[0031] Combine Figure 2 and Figure 3 , the first seal 61 and the first shell 1 are an integral structure, and the first seal 61 extends along the height direction of the heat exchanger 100. In this embodiment, the first shell 1 includes a first side wall 11, and along the height direction of the heat exchanger 100, the first seal 61 extends from the top of the first side wall 11 to the bottom of the first shell 1. In this embodiment, the material of the first seal 61 is rubber, so that the sealing effect of the first seal 61 is good, and the material of the first shell 1 is plastic, so that the manufacturing cost of the first shell 1 is low. The first seal 61 and the first side wall 11 are fixed by a vulcanization process, so that the connection between the first seal 61 and the first shell 1 is simple and stable. The first seal 61 and the first side wall 11 can be directly fixed by vulcanization, or glue can be added.

[0032] In other embodiments, the first seal 61 and the first side wall 11 can also be fixed by injection molding, that is, the first seal 61 is formed by injection molding with the first housing 1 as an insert, and the first seal 61 and the first housing 1 are injection-molded together to form an integral structure. In this way, the connection between the first seal 61 and the first housing 1 is simple and stable. The material of the first seal 61 and the second housing 2 can also be plastic material, and the first seal 61 is soft plastic.

[0033] Combine Figure 2-Figure 3, the first side wall 11 includes a protrusion 12, and the protrusion 12 extends from the first side wall 11 toward the heat exchange core 3. In this embodiment, the protrusion 12 protrudes from the outer wall of the first shell 1 toward the heat exchange core 3. The second shell 2 and the first shell 1 cooperate, and the setting of the protrusion 12 can support the second shell 2. The first shell 1 also includes a first inlet flow channel 16 and a first outlet flow channel 17. Along the width direction of the heat exchanger 100, the first inlet flow channel 16 and the first outlet flow channel 17 are located on both sides of the protrusion 12. The setting of the protrusion 12 can separate the first inlet flow channel 16 and the first outlet flow channel 17, thereby reducing the gap between the heat exchange core 3 and the inner circumferential wall of the first shell 1. In this embodiment, the protrusion 12 includes a mating surface 122, and the first seal 61 is fixed to the mating surface 122 through a vulcanization process. The first seal 61 can separate the first inlet portion 4 and the first outlet portion 5, reduce the flow rate of the first fluid directly flowing out of the heat exchanger 100 from the gap between the heat exchange core 3 and the inner peripheral wall forming the accommodating cavity 101, increase the flow rate of the first fluid flowing into the first heat exchange portion a and the second heat exchange portion b, and improve the heat exchange effect between the first fluid and the second fluid.

[0034] In other embodiments, the boss 12 may also protrude from the inner circumferential wall of the first shell 1 toward the heat exchange core 3 .

[0035] In other embodiments, the first shell 1 may not be provided with the protrusion 12 , and the first inlet flow channel 16 and the first outlet flow channel 17 may be separated by a partition or other sealing structure.

[0036] Combine Figure 2 、 Figure 3 as well as Figure 5 In this embodiment, the first seal 61 abuts the heat exchange core 3. The heat exchange core 3 includes a first end surface 38, and the first seal 61 abuts the first end surface 38. This facilitates more of the first fluid to participate in heat exchange with the second fluid, thereby improving the heat exchange performance of the heat exchanger 100.

[0037] Of course, in other embodiments, the first sealing member 61 and the first end face 38 may also be clearance-fitted, which can also improve the heat exchange performance of the heat exchanger 100 compared to a solution without the first sealing member 61 .

[0038] In other embodiments, the first seal 61 and the first housing 1 are integrally formed, the first seal 61 is made of rubber, the first housing 1 is made of plastic, the first seal 61 and the first housing 1 are formed separately, and the first seal 61 is fixed to the first housing 1 by a vulcanization process. In this embodiment, the first seal 61 is fixed to the mating surface 122 by a vulcanization process.

[0039] In other embodiments, the first sealing member 61 and the first housing 1 may also be separate structures, and the first sealing member 61 and the first housing 1 may be fixedly connected. For example, the first sealing member 61 may be fixed to the mating surface 122 by gluing.

[0040] Combine Figure 10 and Figure 12 In other embodiments, the first sealing member 61 may also be engaged and locked with the first housing 1. For example, the first housing 1 includes a first groove 141, the first sealing member 61 is located in the first groove 141, and the first sealing member 61 abuts against the wall forming the first groove 141. Alternatively, in other embodiments, the first sealing member 61 and the first housing 1 are engaged and fixed, for example, by bonding the first sealing member 61 and the wall forming the first groove 141. In this embodiment, the first groove 141 is provided on the mating surface 122 of the protrusion 12.

[0041] In other embodiments, the first seal 61 and the first shell 1 are split structures, and the first seal 61 is located between the first side wall 11 and the first end face 38. The two side walls of the first seal 61 are respectively in contact with the first side wall 11 and the first end face 38, which can also achieve the effect of improving the heat exchange performance of the heat exchanger 100.

[0042] In other embodiments, the first sealing member 61 may also be fixedly connected to the heat exchange core 3 first, and the connection methods include vulcanization, bonding, etc., and the first sealing member 61 abuts against the first side wall 11 of the first shell 1.

[0043] In other embodiments, the first inlet flow channel 16 and the first outlet flow channel 17 can also be located on both sides of the heat exchanger 100 in the height direction. In this embodiment, the first inlet flow channel 16 is located above the first outlet flow channel 17, with the opening of the wall forming the first inlet flow channel 16 facing upward and the opening of the wall forming the first outlet flow channel 17 facing downward. The first seal 61 separates the first inlet flow channel 16 and the first outlet flow channel 17 along the height direction of the heat exchanger 100. The first seal 61 helps reduce the first fluid from flowing out of the first outlet flow channel 17 from the first inlet flow channel 16 along the gap between the heat exchange core 3 and the inner circumferential wall forming the accommodating cavity 101. This can also reduce the flow rate of the first fluid that directly flows out of the heat exchanger 100 along the gap between the heat exchange core 3 and the inner circumferential wall forming the accommodating cavity 101, thereby improving the heat exchange effect of the exchanger 100. The first inlet flow channel 16 and the first outlet flow channel 17 can be aligned or not aligned along the height direction of the heat exchanger 100.

[0044] Combine Figure 2 、 Figure 3 as well as Figure 9In this embodiment, the heat exchanger 100 includes a second seal 62. The second seal 62 and the protrusion 12 are fixed via a vulcanization process. Along the length of the heat exchanger 100, the second seal 62 extends from one end of the protrusion 12 to the other. One end of the second seal 62 is close to the heat exchange core 3, while the other end is away from the heat exchange core 3. The second seal 62 is located between the first inlet 4 and the first outlet 5. In this embodiment, when the second shell 2 and the first shell 1 are mated, the second shell 2 and the second seal 62 abut against each other. The convex portion 12 includes a first upper wall 121. When the second shell 2 and the first shell 1 are matched, there is a gap between the second shell 2 and the first upper wall 121 of the convex portion 12. A second seal 62 is provided. When the second shell 2 and the first shell 1 are matched, the second shell 2 and the second seal 62 abut against each other, which is beneficial to reducing the flow of the first fluid after flowing into the heat exchanger 100 and directly flowing out of the first outlet portion 5 through the gap between the second shell 2 and the first upper wall 121. This is beneficial for more first fluid to participate in heat exchange with the second fluid, thereby improving heat exchange.

[0045] Combine Figure 2 、 Figure 3 as well as Figure 9 In this embodiment, the second seal 62 and the first upper wall 121 are fixed together via a vulcanization process. The second housing 2 includes a first lower wall 21, which is the wall of the second housing 2 on the side closest to the heat exchange core 3. The second seal 62 abuts against the first lower wall 21. The second seal 62, the first seal 61, and the fifth seal 65 are integrally formed, simplifying the structure of the heat exchanger 100.

[0046] In other embodiments, the second sealing member 62 and the protrusion 12 may also be fixed by injection molding.

[0047] Combine Figure 11 and Figure 12 In other embodiments, the second sealing member 62 and the first housing 1 are separate structures, and the second sealing member 62 and the protrusion 12 can be fixedly connected, including by gluing. Alternatively, the second sealing member 62 and the protrusion 12 are fixed or positioned by snapping. For example, the protrusion 12 includes a second groove 142, the second sealing member 62 is located in the second groove 142, and the second sealing member 62 abuts against the wall forming the second groove 142. Alternatively, the second sealing member 62 and the wall forming the second groove 142 are fixed by bonding.

[0048] In other embodiments, the second sealing member 62 and the first lower wall 21 of the second shell 2 may also be clearance-fitted, which may also reduce the gap between the second shell 2 and the first upper wall 121 of the protrusion 12 and improve the heat exchange effect.

[0049] In other embodiments, the second seal 62 and the first seal 61 are split structures, and one end of the second seal 62 is arranged in contact with one end of the first seal 61, which is also beneficial to reducing the flow rate of the first fluid flowing through the gap between the second shell 2 and the protrusion 12.

[0050] Combine Figure 2-Figure 4 In this embodiment, the first shell 1 includes a second sidewall 13, which is located at opposite ends of the first shell 1 and opposite to the first sidewall 11. The heat exchange core 3 includes a second end surface 39, which is located opposite to the first end surface 38. The heat exchanger 100 includes a third seal 63, which is located between the second sidewall 13 and the second end surface 39. The third seal 63 and the first seal 61 are located at opposite ends of the heat exchanger 100. In this embodiment, the first seal 61 is located at the first end 8 of the heat exchanger 100, and the third seal 63 is located at the second end 9 of the heat exchanger 100.

[0051] Combine Figure 2-Figure 4 、 Figure 6 The third seal 63 and the second side wall 13 are fixed by a vulcanization process, so that the connection between the third seal 63 and the second side wall 13 is simple. Along the height direction of the heat exchanger 100, the third seal 63 extends from the top of the second side wall 13 to the bottom of the second side wall 13. In this embodiment, the third seal 63 abuts the second end face 39 of the heat exchange core 3, which helps to reduce the flow rate of the first fluid flowing through the gap between the heat exchange core 3 and the second side wall 13. This allows more first fluid to flow through the first fin 33 or the second fin 34, thereby helping to improve the heat exchange between the first fluid and the second fluid. In addition, the provision of the third seal 63 helps prevent the first fluid from flowing directly out of the first outlet 5 after circling the gap between the heat exchange core 3 and the inner circumferential wall of the first shell 1. The provision of the third seal 63 allows more first fluid to participate in heat exchange, thereby improving the heat exchange effect of the heat exchanger 100.

[0052] In other embodiments, the third seal 63 and the second end face 39 may also be clearance-fitted, which may also reduce the flow of the first fluid passing through the gap between the second end face 39 and the second side wall 13 , thereby improving the heat exchange effect of the heat exchanger 100 .

[0053] In other embodiments, the third sealing member 63 may also be fixed to the second side wall 13 by an injection molding process.

[0054] In other embodiments, the third sealing member 63 may also be fixedly connected to the second side wall 13 , and the connection method includes gluing.

[0055] Combine Figure 10 and Figure 11In other embodiments, the third sealing member 63 and the second side wall 13 may also be fixed or limited by snapping. The first housing 1 is provided with a third groove 143, and the third sealing member 63 is located in the third groove 143. The third sealing member 63 abuts against the wall forming the third groove 143, or the third sealing member 63 and the wall forming the third groove 143 are bonded.

[0056] In other embodiments, the third sealing member 63 may also be first fixedly connected to the heat exchange core 3 by vulcanization, bonding, etc., and the third sealing member 63 abuts against the second side wall 13 .

[0057] Combine Figure 2-Figure 5 In this embodiment, the heat exchanger 100 includes a fourth seal 64, the first shell 1 includes a first bottom wall 15, and the fourth seal 64 is located between the first bottom wall 15 and the heat exchange core 3. The fourth seal 64 and the first bottom wall 15 are fixed by a vulcanization process. Along the height direction of the heat exchanger 100, the deflector plate 35 and the fourth seal 64 are aligned, the bottom of the deflector plate 35 abuts the fourth seal 64, and the fourth seal 64 extends along the length direction of the heat exchanger 100. The first seal 61 is located between the first header assembly 36 and the second header assembly 37. The fourth seal 64 is not connected to the first seal 61 and the third seal 63. The provision of the fourth seal 64 helps prevent the first fluid from directly flowing out of the heat exchanger 100 from the gap between the first bottom wall 15 and the bottom of the deflector plate 35, thereby improving the heat exchange effect. In this embodiment, the fourth seal 64 is also made of rubber.

[0058] In other embodiments, the fourth seal 64 may also abut the heat exchange core 3. The fourth seal 64 is disposed on one side of the first fin 33. This helps prevent the first fluid from flowing directly out of the heat exchanger 100 through the gap between the first bottom wall 15 and the heat exchange core 3, thereby improving the heat exchange effect. In other embodiments, the fourth seal 64 may be connected to the first seal 61 or the third seal 63. In other embodiments, the fourth seal 64 and the heat exchange core 3 may also have a clearance fit. This can reduce the flow rate of the first fluid that directly flows out of the heat exchanger 100 through the gap between the first bottom wall 15 and the heat exchange core 3, thereby improving the heat exchange effect.

[0059] In other embodiments, the fourth sealing member 64 may also be fixed to the first bottom wall 15 by an injection molding process, that is, the fourth sealing member 64 is formed by injection molding with the first housing 1 as an insert.

[0060] In other embodiments, the fourth sealing member 64 and the first bottom wall 15 may also be fixedly connected, for example, by gluing.

In other embodiments, the sealing portion 6 and the first housing 1 can also be fixed by a snap fit. For example, the sealing portion 6 and the wall forming the groove 14 are bonded together.

[0068] The fourth seal 64 and the first housing 1 are separate structures. The first bottom wall 15 surrounds the fifth groove 145. The fourth seal 64 is located in the fifth groove 145. The fourth seal 64 abuts the wall forming the fifth groove 145, thereby improving the heat transfer efficiency of the heat exchanger 100. In other embodiments, the fourth seal 64 and the wall forming the fifth groove 145 can also be bonded and fixed.

[0069] In other embodiments, at least one of the second seal 62 and the third seal 63 is a separate structure from the fifth seal 65, and the first, second, third, and fifth seals 61, 62, 63, and 65 are formed by insert molding using the first housing 1. Alternatively, at least one of the second seal 62 and the third seal 63 is a separate structure from the fifth seal 65, and the first, second, third, and fifth seals 61, 62, 63, and 65 are secured to the first housing 1 via a vulcanization process. Alternatively, at least one of the second seal 62 and the third seal 63 is a separate structure from the fifth seal 65, and the first housing 1 includes a groove 14, which includes a first groove 141, a second groove 142, a third groove 143, and a fourth groove 144. The first seal 61 is located in the first groove 141, the second seal 62 is located in the second groove 142, the third seal 63 is located in the third groove 143, and the fifth seal 65 is located in the fourth groove 144.
