Therefore, it is necessary to cool down the new energy batteries to prevent the new energy batteries from malfunctioning or even exploding due to overheating. Usually, a heat exchanger is used to cool down the new energy batteries, and the heat exchanger includes a shell and a heat exchange component. The shell is provided with a heat exchange flow channel. The heat exchange component is arranged in the heat exchange flow channel. The heat exchange medium flowing in the heat exchange flow channel can be heat exchanged through the heat exchange component. There is a bypass flow channel between the heat exchange component and the heat exchange flow channel.

[0032] New energy batteries generate a lot of heat during use. Therefore, it is necessary to cool down the new energy batteries to prevent them from malfunctioning or even exploding due to overheating. Figure 1 , Figure 2 and Figure 4 Usually, a heat exchanger is used to cool down the new energy battery, and the heat exchanger includes a shell 100 and a heat exchange component 200. The shell 100 is provided with a heat exchange channel 110, and the heat exchange component 200 is arranged in the heat exchange channel 110. The heat exchange medium flowing in the heat exchange channel 110 can exchange heat through the heat exchange component 200, and a bypass channel 140 is provided between the heat exchange component 200 and the heat exchange channel 110. It should be noted that the bypass channel 140 is usually an assembly gap between the shell 100 and the heat exchange component 200, and the assembly gap can be located on one side of the heat exchange component 200, and can also be located on both sides of the heat exchange component 200, but is not limited thereto.

[0033] When the heat exchange medium flows in the heat exchange channel 110, a part of the heat exchange medium passes through the heat exchange component 200, and another part of the heat exchange medium passes through the bypass channel 140. The heat exchange medium passing through the heat exchange component 200 can effectively exchange heat with the heat exchange component 200, while the heat exchange medium passing through the bypass channel 140 cannot exchange heat with the heat exchange component 200, thereby greatly reducing the heat exchange efficiency of the heat exchanger. In order to solve the problem of low heat exchange efficiency of the heat exchanger, the prior art usually increases the total heat exchange area of ​​the heat exchange component 200 or increases the number of heat exchange components 200 to improve the heat exchange efficiency of the heat exchanger, but the above technical solution greatly increases the processing cost of the heat exchange component 200, thereby increasing the manufacturing cost of the heat exchanger.

[0034] See also Figure 1 and Figure 3 In order to provide a heat exchanger with high heat exchange efficiency and low manufacturing cost, the present application provides a heat exchanger, which includes a shell 100, a heat exchange component 200 and a flow blocking structure 300. The shell 100 is provided with a heat exchange channel 110, and the heat exchange component 200 is arranged in the heat exchange channel 110. The heat exchange medium flowing in the heat exchange channel 110 can exchange heat through the heat exchange component 200. There is a bypass channel 140 between the heat exchange component 200 and the heat exchange channel 110. In addition, the flow blocking structure 300 is arranged in the bypass channel 140 to separate the bypass channel 140 and the heat exchange channel 110. The working principle of the heat exchanger is that the new energy battery with a higher temperature is attached to the surface of the shell 100, and the heat is transferred to the heat exchange component 200 through the shell 100. After that, the heat exchange medium enters the heat exchange channel 110 from the inlet 120 of the shell 100, and enters the heat exchange component 200 to take away the heat in the heat exchange component 200. Finally, the heat exchange medium leaves the heat exchange channel 110 from the outlet 130 of the shell 100. It should be noted that the heat exchange medium is a refrigerant, and the refrigerant can be liquid water, air or liquid oil, but is not limited to this, and is not listed here one by one. Further, in one embodiment, the shell 100 includes a first shell 101 and a second shell 102, and the second shell 102 and the second shell 102 are detachably connected by fasteners, and the heat exchange channel 110 is arranged on the side end face of the second shell 102 facing the first shell 101. The inlet portion 120 and the outlet portion 130 are provided in the first housing 101, and the inlet portion 120 of the first housing 101 is connected to the inlet pipe 121, and the outlet portion 130 of the first housing 101 is connected to the outlet pipe 131. The first housing 101 is provided with one or more limiting portions 150, and the heat exchange assembly 200 is clamped in the limiting portion 150 to prevent the heat exchange assembly 200 from moving in the heat exchange flow channel 110.

[0035] By setting the flow-blocking structure 300, the flow-blocking structure 300 closes the bypass flow channel 140. When the heat exchange medium flows through the heat exchange flow channel 110, the heat exchange medium cannot pass through the bypass flow channel 140. Therefore, all the heat exchange medium will pass through the heat exchange assembly 200, thereby greatly improving the heat exchange efficiency of the heat exchanger. Moreover, compared with expanding the heat exchange area of the heat exchange assembly 200 or directly increasing the heat exchange assembly 200, directly setting the flow-blocking structure 300 greatly reduces the processing difficulty of the heat exchanger, and further reduces the manufacturing cost of the heat exchanger. In summary, it can be seen that the heat exchanger provided by the present application has high heat exchange efficiency and low manufacturing cost.

[0036] Specifically, in order to reduce the installation difficulty of the flow-blocking structure 300, in one embodiment, as Figure 5-Figure 8 shown, the flow-blocking structure 300 includes a main body portion 310 and a flow-blocking portion 320. The main body portion 310 is connected to the heat exchange assembly 200. One end of the flow-blocking portion 320 is connected to the main body portion 310, and the other end extends in a direction away from the main body portion 310 and cuts off the bypass flow channel 140. In other embodiments, the main body portion 310 can also be connected to the housing 100. One end of the flow-blocking portion 320 is connected to the housing 100, and the other end extends in a direction away from the housing 100 and cuts off the bypass flow channel 140. In one embodiment, the main body portion 310 and the flow-blocking portion 320 can be welded. In another embodiment, the main body portion 310 and the flow-blocking portion 320 can also be snap-connected. In other embodiments, the main body portion 310 and the flow-blocking portion 320 can also be integrally formed sheet metal parts, but not limited thereto, and will not be listed one by one here.

[0037] In order to improve the structural strength of the flow-blocking structure 300 and further reduce the processing difficulty of the flow-blocking structure 300, in one embodiment, as Figure 5-Figure 8 shown, the main body portion 310 includes a fixing plate 311. The fixing plate 311 is connected to the heat exchange assembly 200. One end or both ends of the fixing plate 311 are bent in a direction away from the heat exchange assembly 200 to form the flow-blocking portion 320. Specifically, the fixing plate 311 is strip-shaped, and the length direction of the fixing plate 311 extends along the flow direction of the heat exchange flow channel 110. The fixing plate 311 is attached to the side surface of the heat exchange assembly 200 and fixedly connected to the heat exchange assembly 200. When one end of the fixing plate 311 is bent in a direction away from the heat exchange assembly 200 to form the flow-blocking portion 320, the fixing plate 311 and the flow-blocking portion 320 form an L-shaped structure. When both ends of the fixing plate 311 are bent in a direction away from the heat exchange assembly 200 to form the flow-blocking portion 320, the fixing plate 311 and the flow-blocking portion 320 form a "C" -shaped structure. But not limited thereto, the flow-blocking portion 320 can also be arranged at the middle position of the fixing plate 311.

[0038] In order to improve the connection strength between the flow-blocking structure 300 and the heat exchange assembly 200, in one embodiment, as Figure 5-Figure 8As shown, the main body 310 also includes a fixing hook 312, one end of which is connected to the fixing plate 311, and the other end is connected to the heat exchange assembly 200. Specifically, the fixing hooks 312 are respectively provided at both ends of the fixing plate 311, and the fixing hooks 312 are respectively connected to the two side end surfaces of the heat exchange assembly 200.

[0039] More specifically, in order to improve the connection strength between the fixing hook 312 and the fixing plate 311, in one embodiment, as Figure 5-Figure 8 As shown, partial areas at both ends of the fixing plate 311 are bent toward the heat exchange assembly 200 to form fixed hooks 312, and the fixed hooks 312 are stopped at both sides of the heat exchange assembly 200, and the fixed hooks 312 are welded to the heat exchange assembly 200. It should be noted that "partial areas at both ends of the fixing plate 311 are bent toward the heat exchange assembly 200 to form fixed hooks 312" means that the fixed hooks 312 are integrally formed with the fixing plate 311, and partial areas at both ends of the fixing plate 311 are processed into the fixed hooks 312 by cutting or other processing methods, and the fixed hooks 312 are bent toward the heat exchange assembly 200.

[0040] In order to improve the connection sealing between the baffle 320 and the inner wall of the heat exchange channel 110, in one embodiment, as Figure 3 As shown, the contour shape of the baffle 320 connected to the shell 100 is adapted to the shape of the inner wall of the heat exchange flow channel 110, and the baffle 320 is welded to the shell 100. In this embodiment, the contour shape of the baffle 320 connected to the shell 100 is an arc. Further, the baffle 320 is welded to the shell 100, but it is not limited thereto. The baffle 320 and the shell 100 can also be snap-connected or detachably connected by fasteners.

[0041] Generally, there are bypass channels 140 on both sides of the side wall of the heat exchange component 200 close to the heat exchange channel 110. Therefore, in order to isolate the bypass channels 140 on both sides of the heat exchange component 200, in one embodiment, as shown in FIG. Figure 1 , Figure 5 and Figure 6 As shown, the heat exchange assembly 200 is provided with a flow blocking structure 300 on both sides of the side wall close to the heat exchange channel 110. In addition, in order to further improve the heat exchange efficiency of the heat exchanger, a plurality of heat exchange assemblies 200 are provided in the heat exchange channel 110. In this embodiment, two heat exchange assemblies 200 are provided in the heat exchange channel 110, but it is not limited thereto. The number of heat exchange assemblies 200 can also be three, four or more than four, which are not listed here one by one.

[0042] It should be noted that in order to reduce the structural complexity of the heat exchange assembly 200, in one embodiment, as Figure 5 and Figure 6As shown, the heat exchange assembly 200 includes one or more heat exchange fins 210, and when the heat exchange assembly 200 includes multiple heat exchange fins 210, adjacent heat exchange fins 210 are abutted or welded. Further, in order to increase the heat exchange area of ​​the heat exchange fins 210, the cross section of the heat exchange fins 210 is wavy. It should be noted that in this embodiment, the thickness of the multiple heat exchange fins 210 is different. It should be noted that the thickness of the heat exchange fins 210 refers to the length of the heat exchange fins 210 along the direction perpendicular to the bottom wall of the heat exchange channel 110.

[0043] In order to make the temperature inside the heat exchange medium more uniform and improve the utilization rate of the heat exchange medium, in one embodiment, as Figure 6-Figure 8 As shown, the heat exchange assembly 200 includes a plurality of heat exchange fins 210 distributed along the flow direction of the heat exchange channel 110, and a partition assembly 400 is provided between adjacent heat exchange fins 210, and the partition assembly 400 is used to control the spacing between adjacent heat exchange fins 210. Generally, the temperature of the heat exchange medium close to the surface of the heat exchange fin 210 is higher and the temperature of the inside away from the heat exchange fin 210 is lower. At this time, it is not conducive for the heat exchange medium to fully absorb the heat of the heat exchange fin 210. The partition assembly 400 can be used to provide a gap between adjacent heat exchange fins 210. When the heat exchange medium leaves the previous heat exchange fin 210 and directly enters the gap between two heat exchange fins 210, the heat exchange medium itself will be disturbed and remixed. At this time, the temperature difference between the internal and external heat exchange medium is reduced, thereby reducing the temperature of the surface of the heat exchange medium close to the heat exchange fin 210 and improving the heat exchange capacity of the heat exchange medium.

[0044] Specifically, in order to improve the connection strength between the partition assembly 400 and the baffle structure 300, in one embodiment, as shown in FIG. Figure 6-Figure 8 As shown, the partition assembly 400 includes a first partition baffle 410 and a second partition baffle 420, one end of the first partition baffle 410 and one end of the second partition baffle 420 are respectively connected to the baffle structure 300, and one end of the first partition baffle 410 and the other end of the second partition baffle 420 extend toward the adjacent heat exchange fins 210, so that the adjacent heat exchange fins 210 are respectively stopped by one end of the first partition baffle 410 and the second partition baffle 420. During the processing of the partition assembly 400, the distance between the first partition baffle 410 and the second partition baffle 420 can be set to control the gap size between the adjacent heat exchange fins 210. In addition, the first partition baffle 410 and the second partition baffle 420 are both integrally formed with the baffle structure 300.

[0045] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
