For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The heat exchanger 100 according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0035] like Figures 1 to 4 As shown, according to the heat exchanger 100 of the embodiment of the present invention, the heat exchanger 100 includes: a heat exchange body 10 and a flow balancing pipe 20.

[0036] The heat exchange body 10 has a medium inlet 11 and a plurality of medium flow layers 12 , and the plurality of medium flow layers 12 are sequentially arranged at intervals.

[0037] The flow balancing pipeline 20 is connected to the medium inlet 11 . The flow balancing pipeline 20 is provided with a plurality of medium discharge outlets 21 . The medium discharge outlets 21 are correspondingly connected to the medium flow layer 12 .

[0038] Specifically, part of the medium flow layer 12 is used for the flow of the first heat exchange medium, which enters the medium flow layer 12 from the medium inlet 11, and another part of the medium flow layer 12 is used for the flow of the second heat exchange medium, which exchanges heat with the first heat exchange medium to achieve the heat exchange effect of the heat exchanger 100.

[0039] More specifically, the first heat exchange medium enters the medium flow layer 12 from the medium inlet 11 through the flow equalization pipe 20 , and the flow equalization pipe 20 is provided with a medium discharge port 21 connected to the medium flow layer 12 , and the first heat exchange medium enters the medium flow layer 12 through the medium discharge port 21 .

[0040] The area of ​​some of the medium outlets 21 is different from the area of ​​another part of the medium outlets 21 .

[0041] In the related art, the heat exchanger is formed by stacking a plurality of laminations, and a circuit is formed between two adjacent laminations. The circuit includes a plurality of refrigerant circuits and a plurality of coolant circuits. Refrigerant flows in the refrigerant circuit, and coolant flows in the coolant circuit. The refrigerant and the coolant exchange heat to achieve the heat exchange effect of the heat exchanger. However, the refrigerant enters the plurality of refrigerant circuits from one inlet, and the flow rates of the refrigerants entering the plurality of refrigerant circuits are different, resulting in different heat in different parts of the heat exchanger, and the heat exchange capacity of the heat exchanger cannot be fully utilized. For example, compared with the refrigerant circuit close to the inlet, the refrigerant flow rate of the refrigerant circuit far from the inlet is small.

[0042] The present application improves the specificity by setting the area of ​​some medium discharge ports 21 to be different from the area of ​​other medium discharge ports 21, so that the heat of each part of the heat exchanger 100 is the same and the heat exchange capacity of the heat exchanger 100 is fully utilized.

[0043] For example, the medium inlet 11 is located on one side of the flow balancing pipe 20, and the area of ​​the medium outlet 21 connected to the medium flow layer 12 far from the medium inlet 11 is larger than that of the medium flow layer 12 close to the medium inlet 11, so that the amount of medium in multiple medium flow layers 12 is the same, and the heat of each part of the heat exchanger 100 is the same, and the heat exchange capacity of the heat exchanger 100 is fully utilized; or, there are multiple medium inlets 11, and the multiple medium inlets 11 are located on both sides of the flow balancing pipe 20, and the area of ​​the medium outlet 21 in the middle part is larger than that of the medium outlet 21 at both ends of the flow balancing pipe 20.

[0044] According to the heat exchanger 100 of the embodiment of the present invention, a flow-equalizing pipe 20 having a plurality of medium discharge ports 21 is provided, and the area of ​​some medium discharge ports 21 is different from the area of ​​other medium discharge ports 21, so that the heat of each part of the heat exchanger 100 is the same, and the heat exchange capacity of the heat exchanger 100 is fully utilized.

[0045] In some embodiments, the medium flow layers 12 for circulating the first heat exchange medium and the medium flow layers 12 for circulating the second heat exchange medium are arranged alternately, so that the first heat exchange medium and the second heat exchange medium can fully exchange heat.

[0046] like Figure 1 , Figure 3 As shown, in some embodiments, one end of the flow balancing pipe 20 is connected to the medium inlet 11 , and a plurality of medium discharge ports 21 are distributed at intervals in a direction away from the medium inlet 11 .

[0047] Among them, the multiple medium outlets 21 include: a first outlet 211 and a second outlet 212. The second outlet 212 is located on the side of the first outlet 211 away from the medium inlet 11, and the area of the second outlet 212 is larger than that of the first outlet 211. By providing the first outlet 211 and the second outlet 212, with the second outlet 212 located on the side of the first outlet 211 away from the medium inlet 11 and the area of the second outlet 212 being larger than that of the first outlet 211, the amount of heat exchange medium in the medium flow layer 12 close to the medium inlet 11 is the same as that in the medium flow layer 12 away from the medium inlet 11, so that the heat in each part of the heat exchanger 100 is the same, and the heat exchange capacity of the heat exchanger 100 is fully exerted.

[0048] Specifically, the first outlet 211 can be one or multiple. Similarly, the second outlet can be one or multiple.

[0049] In some embodiments, the diameter of the second outlet 212 is 0.2 mm larger than that of the first outlet 211. By setting the diameter of the second outlet 212 to be 0.2 mm larger than that of the first outlet 211, the 2-mm difference makes the amount of heat exchange medium in the medium flow layer 12 close to the medium inlet 11 the same as that in the medium flow layer 12 away from the medium inlet 11, so that the heat in each part of the heat exchanger 100 is the same, and the heat exchange capacity of the heat exchanger 100 is fully exerted. For example, the diameter of the first outlet 211 is 1 mm, and the diameter of the second outlet 212 is 1.2 mm.

[0050] In some embodiments, the length of the flow equalizing pipe 20 is L1, the distance between the first outlet 211 and the medium inlet 11 is L2, where 0 < L2 ≤ 0.3L1, and the distance between the second outlet 212 and the medium inlet 11 is L3, where 0.3L1 < L3 ≤ L1. By setting the distance L2 between the first outlet 211 and the medium inlet 11 to satisfy 0 < L2 ≤ 0.3L1 and the distance L3 between the second outlet 212 and the medium inlet 11 to satisfy 0.3L1 < L3 ≤ L1, the heat in each part of the heat exchanger 100 is the same, and the heat exchange capacity of the heat exchanger 100 is fully exerted.

[0051] Specifically, there are multiple first outlets 211, and the multiple first outlets 211 are located in the first 1 / 3 section close to the medium inlet 11. There are multiple second outlets 212, and the multiple second outlets 212 are located in the latter 2 / 3 section away from the medium inlet 11, giving full play to the effects of each part.

[0052] As Figure 1 shown, in some embodiments, the heat exchange body 10 includes: a heat exchange plate 13, a first side plate 14, and a second side plate 15.

[0053] The first side plate 14 and the second side plate 15 are respectively disposed on two opposite sides of the heat exchange plate 13 .

[0054] The medium inlet 11 is disposed on either the first side plate 14 or the second side plate 15, and one end of the flow balancing pipe 20 away from the medium inlet 11 is connected to the other of the first side plate 14 and the second side plate 15. By disposing the medium inlet 11 on either the first side plate 14 or the second side plate 15, and one end of the flow balancing pipe 20 away from the medium inlet 11 is connected to the other of the first side plate 14 and the second side plate 15, compared with the solution in the related art in which one end of the flow balancing pipe is suspended, the present application makes the flow balancing pipe 20 more stable.

[0055] For example, the medium inlet 11 is arranged on the first side plate 14, and the end of the flow equalizing pipe 20 away from the medium inlet 11 is connected to the second side plate 15, and the second side plate 15 is used to position the flow equalizing pipe 20, thereby improving the stability of the flow equalizing pipe 20; or, the medium inlet 11 is arranged on the second side plate 15, and the end of the flow equalizing pipe 20 away from the medium inlet 11 is connected to the first side plate 14, and the first side plate 14 is used to position the flow equalizing pipe 20, thereby improving the stability of the flow equalizing pipe 20.

[0056] In some embodiments, a first bonding member is provided at one end of the flow balancing pipe 20 away from the medium inlet 11, and the first bonding member is bonded to one of the first side plate 14 and the second side plate 15. By providing the first bonding member to bond the flow balancing pipe 20, the stability of the flow balancing pipe 20 is further improved. For example, the material of the first bonding member is a brazing composite material, and the flow balancing pipe 20 is stably connected to the first side plate 14 or the second side plate 15 by a brazing process, without the need for complicated fastening structures such as bolts and nuts.

[0057] like Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments, the heat exchange plate 13 is provided with an avoidance hole 131 , and the flow balancing pipe 20 is passed through the avoidance hole 131 .

[0058] The flow balancing pipe 20 is provided with a second bonding member, and the second bonding member is bonded to the inner wall of the avoidance hole 131. By providing the second bonding member, the force points of the flow balancing pipe 20 are increased, and the stability of the flow balancing pipe 20 is further improved.

[0059] Specifically, the material of the second bonding member is a brazing composite material, and the flow-equalizing pipe 20 is stably connected to the heat exchange plate 13 by a brazing process, without the need for complicated fastening structures such as bolts and nuts. The brazing process stably connects the flow-equalizing pipe 20 to the heat exchange plate 13, and at the same time, the brazing composite material is filled between the flow-equalizing pipe 20 and the inner wall of the avoidance hole 131, isolating two adjacent medium flow layers 12.

[0060] like Figure 5 As shown, in some embodiments, the avoidance hole 131 includes a first hole 1311 , a second hole 1312 , a third hole 1313 and a fourth hole 1314 .

[0061] The first hole 1311 and the second hole 1312 are located at one end of the heat exchange plate 13, and the third hole 1313 and the fourth hole 1314 are located at the other end of the heat exchange plate 13. Any one or more of the first hole 1311, the second hole 1312, the third hole 1313 and the fourth hole 1314 is penetrated by a flow balancing pipe 20.

[0062] That is to say, any one of the first hole 1311, the second hole 1312, the third hole 1313 and the fourth hole 1314 may be provided with a flow balancing pipe 20, while the other three holes may not be provided with the flow balancing pipe 20; or, any two of the first hole 1311, the second hole 1312, the third hole 1313 and the fourth hole 1314 may be provided with a flow balancing pipe 20, while the other two holes may not be provided with the flow balancing pipe 20; or, any three of the first hole 1311, the second hole 1312, the third hole 1313 and the fourth hole 1314 may be provided with a flow balancing pipe 20, while the other one may not be provided with the flow balancing pipe 20; or, the first hole 1311, the second hole 1312, the third hole 1313 and the fourth hole 1314 may all be provided with a flow balancing pipe 20.

[0063] For example, a flow equalizing pipe 20 is passed through the first hole 1311, and the flow equalizing pipe 20 is connected to the medium inlet 11. The first heat exchange medium enters the heat exchange body 10 from the medium inlet 11, and the first heat exchange medium passes through a medium flow layer 12 and is discharged from the heat exchange body 10 from the second hole 1312. The second heat exchange medium enters the adjacent medium flow layer 12 from the third hole 1313 and is discharged from the heat exchange body 10 through the fourth hole 1314, thereby performing heat exchange between the first heat exchange medium and the second heat exchange medium.

[0064] like Figure 6 As shown, more specifically, the medium flow layer 12 is provided with a first guide 121 and a second guide, the first guide 121 is provided between the first hole 1311 and the second hole 1312, and extends along the length direction of the medium flow layer 12, and the second guide is provided between the third hole 1313 and the fourth hole 1314, and extends along the length direction of the medium flow layer 12. By providing the first guide 121 and the second guide, the path length of the heat exchange medium flow is lengthened, thereby improving the heat exchange effect.

[0065] like Figure 5 As shown, more specifically, there are multiple heat exchange plates 13, and the multiple heat exchange plates 13 are stacked between the first side plate 14 and the second side plate 15, and the first holes 1311, the second holes 1312, the third holes 1313 and the fourth holes 1314 of the multiple heat exchange plates 13 are correspondingly arranged.

[0066] like Figure 5 As shown, in some embodiments, the medium inlet 11 is provided on the first side plate 14, and the first side plate 14 is also provided with a medium outlet 141. The medium inlet 11 corresponds to the first hole 1311, and the medium outlet 141 corresponds to the second hole 1312. The second side plate 15 is provided with a medium inlet and a medium outlet 21. The medium inlet corresponds to the third hole 1313, and the medium outlet 21 corresponds to the fourth hole 1314.

[0067] Specifically, the medium inlet 11 is used to introduce the first heat exchange medium, the medium outlet 141 is used to discharge the first heat exchange medium, the medium inlet is used to introduce the second heat exchange medium, and the medium outlet 21 is used to discharge the second heat exchange medium. By arranging the medium inlet 11 and the medium outlet 141 on the first side plate 14, and arranging the medium inlet and the medium outlet 21 on the second side plate 15, the first heat exchange medium and the second heat exchange medium can fully exchange heat.

[0068] like Figure 6 As shown, in some embodiments, the flow balancing pipe 20 is arranged near the edge of the heat exchange body 10, and the flow balancing pipe 20 has a first side and a second side. The first side is closer to the edge of the heat exchange body 10 than the second side, and the medium flow rate of the medium outlet 21 arranged on the second side is greater than the medium flow rate of the medium outlet 21 on the first side. By setting the medium flow rate of the medium outlet 21 on the second side to be greater than the medium flow rate of the medium outlet 21 on the first side, the heat exchange medium flows more in the main flow direction, further improving the pertinence and the heat exchange effect.

[0069] For example, the area of ​​the medium discharge port 21 on the second side is greater than that of the medium discharge port 21 on the first side; or the number of the medium discharge port 21 on the second side is greater than that of the medium discharge port 21 on the first side.

[0070] like Figure 6 As shown, in some embodiments, the number of the medium outlets 21 on the first side is less than the number of the medium outlets 21 on the second side. By setting the number of the medium outlets 21 on the first side to be less than the number of the medium outlets 21 on the second side, the targeting is further improved and the heat exchange effect is improved. For example, the first side is the left side, the second side is the right side, the number of the medium outlets 21 on the left side is 2, and the number of the medium outlets 21 on the right side is 3.

[0071] In some embodiments, the flow balancing pipe 20 is constructed as an aluminum pipe to improve the thermal conductivity.

[0072] Specifically, the wall thickness of the flow-balancing pipe 20 is δ, 1mm≤δ≤1.5mm, and the heat conduction capacity is fully exerted. For example, the wall thickness δ of the flow-balancing pipe 20 is 1mm; or, the wall thickness δ of the flow-balancing pipe 20 is 1.5mm; or, the wall thickness δ of the flow-balancing pipe 20 is 1.3mm.

[0073] More specifically, the inner diameter of the flow-equalizing pipe 20 is φ, 9 mm ≤ φ ≤ 13 mm, and the flow is fully guided. For example, the inner diameter φ of the flow-equalizing pipe 20 is 9 mm; or, the inner diameter φ of the flow-equalizing pipe 20 is 13 mm; or, the inner diameter φ of the flow-equalizing pipe 20 is 10 mm.

[0074] Combine the following Figures 1 to 7 , describing a specific embodiment of the heat exchanger 100 of the present invention.

[0075] A heat exchanger 100 includes a heat exchange body 10 and a flow balancing pipe 20 .

[0076] The heat exchange body 10 includes a first side plate 14 , a second side plate 15 and a plurality of heat exchange plates 13 .

A medium flow layer 12 is formed between the first side plate 14 and the heat exchange plate 13, a medium flow layer 12 is formed between the second side plate 15 and the heat exchange plate 13, and a medium flow layer 12 is formed between adjacent heat exchange plates 13. The heat exchange plate 13 is provided with a first hole 1311, a second hole 1312, a third hole 1313, and a fourth hole 1314. The first hole 1311, the second hole 1312, the third hole 1313, and the fourth hole 1314 on the plurality of heat exchange plates 13 correspond to each other. The first hole 1311 corresponds to the medium inlet 11, the second hole 1312 corresponds to the medium outlet 141, the third hole 1313 corresponds to the medium inlet, and the fourth hole 1314 corresponds to the medium outlet 21. A first guide member 121 is disposed between the first hole 1311 and the second hole 1312 and is located in the medium flow layer 12 . A second guide member is disposed between the third hole 1313 and the fourth hole 1314 and is located in the medium flow layer 12 .

[0079] The flow equalizing pipe 20 is passed through the first hole 1311. The flow equalizing pipe 20 is constructed as an aluminum tube. One end of the flow equalizing pipe 20 is connected to the medium inlet 11, and the other end is connected to the second side plate 15 through a first adhesive. The surrounding wall of the flow equalizing pipe 20 is connected to the inner wall of the first hole 1311 through a second adhesive. The materials of the first adhesive and the second adhesive are both brazing composite materials, and the flow equalizing pipe 20 is fixed by a brazing process.

There are a plurality of medium outlets 21 connected to the same medium flow layer 12, the flow-equalizing pipe 20 is arranged close to the edge of the heat exchange body 10, the flow-equalizing pipe 20 has a first side and a second side, the first side is closer to the edge of the heat exchange body 10 than the second side, and the number of medium outlets 21 on the first side is less than the number of medium outlets 21 on the second side.

[0081] The flow-equalizing pipe 20 is a hollow aluminum tube with both ends open but not closed. The heat exchange body 10 is inserted from the medium inlet 11, the bottom contacts the second side plate 15, and the top contacts the first side plate 14. Its length is the same as the height of the heat exchange body 10, so that the flow-equalizing pipe 20 can fully penetrate the heat exchange body 10. The outer diameter of the flow-equalizing pipe 20 is equal to the inner diameter of the first hole 1311, so that the outer wall of the flow-equalizing pipe 20 fits the inner wall of the refrigerant channel formed by stacking multiple layers of heat exchange plates 13. The wall thickness of the flow-equalizing pipe can be 1 to 1.5 mm, and the inner diameter can be 9 to 13 mm.

[0082] The flow-equalizing pipe 20 is provided with a medium discharge port 21, and the diameter of the medium discharge port 21 gradually increases along the flow direction of the first heat exchange medium: holes are opened along the axis at equal intervals L, where L is the center distance between two adjacent first heat exchange medium flow channels. The opening of the hole in the front 1 / 3 section of the flow-equalizing pipe 20 near the inlet of the refrigerant flow channel is 1mm smaller in diameter, and the opening of the hole in the rear 2 / 3 section of the flow-equalizing pipe 20 is 1.2mm larger in diameter. At the same time, holes are also opened along the diameter direction on the flow-equalizing pipe 20. See the radial cross-section of the flow-equalizing pipe for details. Figure 6 In the upper left corner, the right side of the flow equalizer is the main flow direction of the refrigerant, and there are many openings. The left side of the flow equalizer is not the main flow direction of the refrigerant, and there are fewer openings. The ratio of the openings on the left and right sides can be considered to be 1:2.

[0083] The hollow flow-equalizing pipe 20 can first accommodate the first heat exchange medium flowing in from the medium inlet 11, and then flow into the first heat exchange medium's numerous flow channels through the numerous medium outlets 21 on the flow-equalizing pipe 20, and finally converge to the second hole 1312, and flow out of the heat exchange body 10 through the medium outlet 141, completing the entire flow process of the first heat exchange medium in the heat exchanger 100. The holes on the flow-equalizing pipe 20 limit the flow channel at the medium inlet 11 from entering too much first heat exchange medium. The first heat exchange medium in the refrigerant flow channel far away from the medium inlet 11 will not be too little.

[0084] This heat exchanger 100 with the flow-equalizing pipe 20 is also produced by brazing. During the production process, the first heat exchange medium and the heat exchange plate 13, the first side plate 14, the second side plate 15, etc. are combined together, and its outer wall is in contact with the heat exchange plate 13, the first side plate 14 and the second side plate 15. These contact positions will have brazing composite materials, which can tightly weld the flow-equalizing pipe 20 and surrounding parts together during the brazing process. The production process is simple and does not require complicated fastening structures such as bolts and nuts.
