Description

Technical Field

[0002] In the existing thermal management system design, the thermal management design scheme of cylindrical batteries usually adopts a connection method of the collectors of multiple cold plate assemblies welded on both sides. However, due to the size of the cylindrical battery, the distance between two adjacent collectors is limited, and there are dimensional tolerances and welding position tolerances between the collectors, which makes it easy for the connection between the two adjacent collectors to produce assembly tolerances, and then the collectors cannot meet the airtightness requirements after being connected to each other. At the same time, due to the distance limitation, the welding difficulty is increased, which reduces the production efficiency.

[0003] Therefore, there is an urgent need to provide a heat exchange component and a battery to solve the problems existing in the prior art to a certain extent. Utility Model Content

[0004] The utility model aims to provide a heat exchange component and a battery, so as to solve to a certain extent the problem that the connection between multiple cooling components has assembly tolerances due to the dimensional tolerances of structural parts, resulting in substandard airtightness.

[0015] The heat exchange plate included in the heat exchange mechanism can provide cooling for multiple groups of batteries. The current collector is arranged at at least one end of the heat exchange plate body, and a pipe joint that can communicate with the current collector is formed on the current collector, so that the connection with the connecting pipe can be achieved through the pipe joint, thereby achieving the connection between two adjacent heat exchange plates.

[0038] like Figure 1-Figure 7As shown, the heat exchange assembly provided by the present application includes a heat exchange mechanism and a connecting pipe 3; the heat exchange mechanism includes a heat exchange plate, the heat exchange plate includes a heat exchange plate body and a collecting part, the collecting part is arranged at at least one end of the heat exchange plate body, the heat exchange plate body has a heat exchange flow channel for supplying heat exchange medium, the collecting part has a collecting cavity connected to the heat exchange flow channel, and a pipe joint connected to the collecting cavity is arranged on the collecting part; the connecting pipe 3 is arranged between two adjacent heat exchange plates, the connecting pipe 3 is connected between the pipe joints, the connecting pipe 3 includes a connecting part and a deformation part 303, one end of the connecting part is connected to the pipe joint, and the other end is connected to the deformation part 303, the connecting pipe 3 includes a deformation part 303 and connecting parts connected to both ends of the deformation part 303, and the ends of the two connecting parts away from the deformation part 303 are respectively connected to the pipe joints of the two heat exchange plates, so that there is an adjustment space between the adjacent heat exchange plates.

[0039] Compared with the prior art, the heat exchange assembly provided by the utility model has the following advantages:

[0040] The heat exchange assembly provided by the utility model includes a plurality of heat exchange plates, which are connected by connecting pipes 3, so as to provide cooling for a plurality of battery groups 8. The current collecting portion is arranged at at least one end of the heat exchange plate body along the first direction S1, and a pipe joint that can communicate with the current collecting cavity is formed on the current collecting portion, so that the connection with the connecting pipe 3 can be achieved through the pipe joint, thereby achieving the connection between two adjacent heat exchange plates.

[0041] Furthermore, since the connecting pipe 3 in the present application includes a connecting portion and a deformation portion 303, and one end of the connecting portion is connected to the pipe joint, and the other end is connected to the deformation portion 303, a certain adjustment space can be provided between two adjacent heat exchange plates, thereby eliminating the problem that the air tightness requirements of the overall device cannot be met after the adjacent heat exchange plates are connected to each other due to dimensional tolerances or water nozzle welding position tolerances.

[0042] It can be understood that the connecting pipe 3 in the present application actually includes two connecting parts and one deforming part 303, and the two connecting parts are located at both ends of the deforming part 303, so that the connection between the pipe joints provided on the two adjacent headers can be achieved through the connecting parts at both ends of the deforming part 303. Accordingly, through the deformation of the deforming part 303, the dimensional tolerance or position offset between the two headers can be eliminated to a certain extent, ensuring the airtightness requirements.

[0043] Alternatively, if Figure 1-Figure 4 As shown, the deformation portion 303 in the present application has a bellows-shaped structure so that the deformation portion 303 can be deformed.

[0044] By making the deformation part 303 adopt a corrugated tube structure, the deformation part 303 can have a change space in multiple directions. Through the deformation part 303, the horizontal and / or height direction offset of two adjacent heat exchange plates can be accommodated, that is, through the deformation of the deformation part 303, not only the dimensional tolerance or position offset during assembly between adjacent collecting parts can be offset, but also the position offset caused by vibration, impact, etc. can be offset, thereby ensuring the airtightness requirements, reducing the difficulty of assembly, and improving overall safety.

[0045] Alternatively, if Figure 4 As shown, one of the pipe joint and the connecting part is a spherical interface, and the other is a spherical joint adapted to the spherical interface, and at least a portion of the spherical joint can be inserted into the spherical interface so that the connecting part and the pipe joint are movably connected. The pipe joint in the present application includes a first pipe joint 101 and a second pipe joint 201 which are respectively arranged on the collecting parts of two adjacent heat exchange plates. In one embodiment, the first pipe joint 101 and the second pipe joint 201 are both formed with a spherical interface, and the connecting part has a spherical joint adapted to the spherical interface, and at least a portion of the spherical joint can be inserted into the spherical interface so that the connecting part and the pipe joint are movably connected. In another embodiment, the first pipe joint 101 and the second pipe joint 201 are both formed with a spherical joint, and the connecting part has a spherical interface matched with the spherical joint, so as to realize the movable connection between the connecting part and the pipe joint.

[0046] The cooperation between the spherical joint and the spherical interface can provide a larger adjustment range, and make the connection and adjustment between the pipe joint and the connecting part smoother.

[0047] Alternatively, if Figure 4 As shown, a seal is provided between the spherical interface and the spherical joint in the present application. The seal is arranged inside the spherical interface or sleeved outside the spherical joint, and the maximum outer diameter of the seal is less than or equal to the maximum inner diameter of the spherical interface.

[0048] By arranging a seal between the spherical interface and the spherical joint, the sealing degree between the spherical interface and the spherical joint can be improved. Since the maximum outer diameter of the seal in the present application is less than or equal to the maximum inner diameter of the spherical interface, it is possible to ensure the sealing performance between the spherical joint and the spherical interface and also to cooperate with the changes in the relative positions of the two to further improve the sealing performance.

[0049] In actual application, the first pipe joint 101 and the second pipe joint 201 in the present application both include a positioning layer 1011 and a sealing connection layer 1012. The sealing connection layer 1012 is the above-mentioned seal. The sealing connection layer 1012 is made of a flexible material, such as TPE or EPDM. The sealing connection layer 1012 made of the flexible material can have a certain deformation and compression amount, thereby ensuring the sealing performance.

[0050] Accordingly, the positioning layer 1011 in the present application can be made of metal, such as aluminum, which can not only control the weight of the overall structure, but also provide an installation basis for the sealing connection layer 1012 to ensure the sealing performance of the overall structure.

[0051] Preferably, a first matching portion 1013 is formed on the outer wall surface of the sealing connection layer 1012 in the present application, and a second matching portion 1014 is formed on the positioning layer 1011 at a position corresponding to the first matching portion 1013, and the first matching portion 1013 in the present application is a protrusion, and the second matching portion 1014 is a positioning groove. Through the cooperation of the first matching portion 1013 and the second matching portion 1014, a stable connection between the sealing connection layer 1012 and the positioning layer 1011 can be achieved, which can avoid the problem of wrinkling or displacement of the sealing connection layer 1012 caused by the spherical joint during installation to a certain extent, and can also further increase the contact area between the two and improve the sealing performance.

[0052] Alternatively, if Figure 4 As shown, the end of the pipe joint in the application is formed with a straight section 1015, and the dimension of the straight section 1015 in the axial direction of the pipe joint is not less than 5 mm. Specifically, when the pipe joint is a spherical joint, the outer wall of the spherical joint is vertically connected to the collector, and extends in a direction away from the collector where the pipe joint is located to form the straight section 1015, thereby providing an installation distance between the pipe joint and the connecting part, thereby ensuring installation stability and sealing. When the pipe joint is a spherical joint, the outer wall of the spherical joint is vertically connected to the collector, and extends in a direction away from the collector where the pipe joint is located to form the straight section 1015.

[0053] By forming a straight section 1015 at the end of the pipe joint and making the axial dimension of the straight section 1015 not less than 5 mm, the installed seal can be matched to provide sufficient installation space, thereby ensuring the sealing performance between the pipe joint and the connection part.

[0054] Optionally, the outer diameter of the seal in the present application = the inner diameter of the spherical interface ≥ the outer diameter of the spherical joint > the inner diameter of the seal, so that the seal is in a compressed state after the spherical joint is inserted into the spherical interface, thereby improving the sealing performance. It should be noted that the outer diameter of the seal is equal to the inner diameter of the spherical interface, ensuring that the seal can be smoothly installed in the spherical interface, avoiding the seal outer diameter being too small to cause poor sealing performance, and the seal outer diameter being too large to be installed in the spherical interface.

[0055] Optionally, when the pipe joint is a spherical joint, the inner diameter of the spherical joint and / or the inner diameter of the seal is smaller than the diameter of the collecting cavity of the collecting part, so as to adjust the flow rate of the heat exchange medium flowing into the collecting part through the spherical joint and / or the seal; when the pipe joint is a spherical joint, the inner diameter of the seal is smaller than the diameter of the collecting cavity of the collecting part, so as to adjust the flow rate of the heat exchange medium flowing into the collecting part through the seal. Specifically, when the pipe joint is a spherical interface, since the inner diameter of the spherical joint and / or the inner diameter of the seal that matches the pipe joint is smaller than the diameter of the manifold of the manifold, the spherical joints with different inner diameters and / or the seals with different inner diameters can be replaced, so that the flow entering the manifold can be adjusted by the spherical joints with different inner diameters and / or the seals with different inner diameters. For example, when the flow in the manifold is too large, the inner diameter of the spherical joint is reduced to reduce the flow, or the inner diameter of the seal is reduced to reduce the flow; or when the flow in the manifold is too small, a spherical joint with a larger inner diameter and a seal with a larger inner diameter are configured to increase the inner diameter of the flow at this time. It should be noted that its adjustment range is always smaller than the diameter of the manifold to meet the adjustment requirements. Among them, the diameter of the manifold is the inner diameter of the connection between the pipe joint and the manifold. In another embodiment, when the pipe joint is a spherical joint, the spherical interface is sleeved on the spherical joint, and the inner diameter of the sealing member is smaller than the diameter of the collecting cavity of the collecting part. Therefore, the flow entering the collecting cavity can be adjusted by dense components with different inner diameters. For example, the inner diameter of the dense components can be increased to increase the liquid flow into the collecting cavity, or the inner diameter of the dense components can be reduced to reduce the flow. At this time, the inner diameter of the dense components is always smaller than the diameter of the collecting cavity, thereby ensuring the accuracy of the adjustment.

[0056] Based on the above structure, the present application provides another implementation mode, specifically, as follows: Figure 5 Combination Figure 7 As shown, in this embodiment, the opening of the pipe joint faces upward, and the deformation portion 303 includes a first section 304 and a second section 305. One end of the first section 304 is connected to the pipe joint, and the other end is bent and connected to the second section 305, so that the connecting pipe 3 and the pipe joint can be connected from the upper end of the pipe joint. Specifically, the first section 304 is connected to the connecting section of the second section 305, so as to be connected to the two pipe joints through the two first sections 304 respectively.

[0057] like Figure 5 As shown, in this embodiment, it is the second section 305 that can be deformed, and the second section 305 can also be a corrugated tube structure, so that the first section 304 connected to the pipe joint of two adjacent collecting parts can have a position deviation, play a buffering role, improve the sealing degree, and also eliminate dimensional tolerances to improve installation convenience.

[0058] Furthermore, in this embodiment, the pipe joint with the opening facing upward can also reduce the distance between two adjacent collecting parts to a certain extent, and when the connecting pipe 3 is disassembled, it can be disassembled by directly pulling it out with force in the height direction, which is convenient for operation.

[0059] It is understandable that the above structure of the present application provides two implementation modes, one of which is as follows Figure 2 As shown, the connecting pipe 3 is a straight-line structure, and the other is as shown in FIG. Figure 5 As shown, the connecting pipe 3 is a U-shaped structure. In the two embodiments, except for the different structural forms of the connecting pipe 3, other structures are the same.

[0060] Specifically, Figure 6 Combination Figure 7 As shown, both methods include a first header 1 and a second header 2, a first pipe joint 101 is correspondingly arranged on the first header 1, and the first header 1 has two first pipe joints 101, a second pipe joint 201 is correspondingly arranged on the second header 2, and the second header 2 has two second pipe joints 201. The first pipe joint 101 on the first header 1 and the second pipe joint 201 on the second header 2 are arranged oppositely.

[0061] Specifically, refer to Figure 3 and Figure 4 The connecting pipe 3 includes a first connecting portion 301, a deformation portion 303, and a second connecting portion 302 which are connected in sequence. The first connecting portion 301 of the connecting pipe 3 is connected to the first pipe joint 101 on the first collecting portion 1, and the second connecting portion 302 of the connecting pipe 3 is connected to the pipe joint on the second collecting portion 2, so that the communication between the first collecting portion 1 and the second collecting portion 2 can be achieved, and then the communication between the first heat exchange plate body 5 and the second heat exchange plate body 7 can be achieved.

[0062] It should be noted that at least one side surface of the collector is provided with one or two pipe joints connected to the collector cavity. Optionally, two pipe joints are provided on one side surface of the collector of the heat exchange plate, and two pipe joints are provided on the corresponding side surface of the collector of the adjacent heat exchange plate, and the two pipe joints are connected through two connecting pipes 3, respectively, so as to realize the inlet and outlet of liquid between the heat exchange plates. Furthermore, two pipe joints are provided on the corresponding two side surfaces of the collector of the same heat exchange plate, and two pipe joints are provided on the corresponding side surfaces of the collectors of the two adjacent heat exchange plates, respectively, so as to realize the inlet and outlet of liquid between multiple heat exchange plates. For example, for multiple heat exchange plates arranged in sequence, namely the first heat exchange plate, the second heat exchange plate, and the third heat exchange plate, the pipe joint located at the upper end of the collecting part is used for liquid inlet, and the pipe joint located at the lower end of the collecting part is used for liquid outlet, so that the liquid flows in from the pipe joint at the upper end of the first collecting part 1 of the first heat exchange plate, the pipe joint at the upper end of the second collecting part 2 of the second heat exchange plate, and the pipe joint at the upper end of the third collecting part 4 of the third heat exchange plate, and flows out from the pipe joint at the lower end of the first collecting part 1, the pipe joint at the lower end of the second collecting part 2, and the pipe joint at the lower end of the third collecting part 4, respectively, to realize parallel connection of multiple heat exchange plates.

[0063] Specifically, the first heat exchange plate body 5 and the second heat exchange plate body 7 in the present application both have a U-shaped cooling channel, that is, Figure 2 Combination Figure 6 and Figure 7 As shown, the coolant can be transmitted by the connecting pipe 3 located at the upper end of the collecting part, and enter the first heat exchange plate body 5 and the second heat exchange plate body 7 through the pipe joints located at the upper ends of the first collecting part 1 and the second collecting part 2. Accordingly, the other end of the first heat exchange plate body 5 along the first direction S1 in the present application is connected to the third collecting part 4, and the other end of the second heat exchange plate body 7 along the first direction S1 is connected to the fourth collecting part 6, so that the coolant entering the first heat exchange plate body 5 can enter the third collecting part 4, and the coolant entering the second heat exchange plate body 7 can enter the fourth collecting part 6, and through the transmission of the third collecting part 4 and the fourth collecting part 6, it flows back to the lower area of ​​the U-shaped flow channel in the first heat exchange plate body 5 and the second heat exchange plate body 7, and the pipe joint connected to the lower ends of the first collecting part 1 and the second collecting part 2 realizes the reflux of the coolant, thereby realizing the circulation of the coolant.

[0064] Optionally, both ends of the heat exchange plate along the first direction may be provided with a collecting portion, and a pipe joint is provided on one side surface of the collecting portion. The pipe joints between adjacent heat exchange plates may also be connected through a connecting pipe 3, that is, a pipe joint is provided on the same side surface of the collecting portion at both ends of the heat exchange plate along the first direction S1, and the pipe joints at both ends may be connected to the two pipe joints at both ends of the adjacent heat exchange plate through the connecting pipe 3. Further, a pipe joint is provided on the two corresponding side surfaces of each collecting portion, respectively, to connect two adjacent heat exchange plates. At this time, the flow channel of the heat exchange plate body extends along the first direction, and at this time, the pipe joints at the same end of the multiple heat exchange plates in the first direction S1 are used for liquid inlet, and the pipe joints at the other end are used for liquid outlet, so as to realize parallel connection of multiple heat exchange plates. Of course, when the heat exchange plate is located at the end of the battery 8, only one side surface of the collecting portion is provided with a pipe joint for connection with the adjacent heat exchange plate.

[0065] In addition, the utility model further provides a battery 8, comprising a battery module and the above-mentioned heat exchange assembly, wherein the battery module is located between two adjacent heat exchange plates.

[0066] The battery 8 using the heat exchange assembly provided in the present application can not only cool the battery module, but also make the setting distance, setting angle and relative position between two adjacent battery modules more flexible, thereby reducing the difficulty of the overall battery 8 grouping process and improving the grouping efficiency.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
