The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, but should not be understood as limiting the present disclosure.

[0035] The present disclosure describes a heat exchange assembly 100 according to an embodiment of the present disclosure below.

[0036] like Figure 1 As shown, the heat exchange assembly 100 of the embodiment of the present disclosure includes a plurality of first heat exchange plates 13 and second heat exchange plates 14 .

Figure 1 As shown, the first direction and the second direction may be perpendicular, wherein the first direction may be the front-to-back direction, and the second direction may be the left-to-right direction. The first heat exchange plate 13 may be a rectangular long plate, wherein a plurality of first heat exchange plates 13 may be arranged at intervals along the front-to-back direction, and each first heat exchange plate 13 may extend along the left-to-right direction.

[0038] The second heat exchange plate 14 extends along the first direction and is connected to multiple first heat exchange plates 13. A cavity for accommodating heat exchange medium is formed in the first heat exchange plate 13 and the second heat exchange plate 14. The space 11 for accommodating the battery cell 200 is enclosed between two adjacent first heat exchange plates 13 and second heat exchange plates 14.

[0039] For example, Figure 1 As shown, a plurality of second heat exchange plates 14 may be provided, each of which may extend in the front-rear direction, and a plurality of second heat exchange plates 14 may be arranged at intervals in the left-right direction. The first heat exchange plate 13 and the second heat exchange plate 14 may both be hollow structures, and the internal cavities of the first heat exchange plate 13 and the second heat exchange plate 14 are used for heat exchange medium to flow through.

[0040] Each second heat exchange plate 14 is connected to the plurality of first heat exchange plates 13, and the plurality of second heat exchange plates 14 and the plurality of first heat exchange plates 13 form a grid-type heat exchange plate group 1 as a whole. The heat exchange plate group 1 is provided with a plurality of accommodation spaces 11, which are spaces enclosed by the corresponding first heat exchange plates 13 and second heat exchange plates 14. Figure 1 As shown, each accommodating space 11 may be in the shape of a rectangular hole. In some other embodiments, the accommodating space 11 may also be in the shape of a circular hole, a waist-shaped hole, etc.

[0041] It should be noted that the heat exchange plate group 1 formed above can be a rectangular parallelepiped as a whole. In some other embodiments, the heat exchange plate group 1 can also be cylindrical, prism-shaped, irregular three-dimensional structure, etc. The specific shape of the heat exchange plate group 1 can be adjusted according to the actual use requirements of the layout space.

[0042] During assembly, a battery cell 200 can be installed one by one in each of the multiple receiving spaces 11 of the heat exchange plate group 1, and the side of the battery cell 200 can be in contact with the side wall of the receiving space 11. During use, the heat exchange medium can be passed into the cavity of the first heat exchange plate 13 and the second heat exchange plate 14 through the tube group 2, so that the heat exchange medium will be distributed around each battery cell 200, and the heat exchange between the heat exchange medium and the battery cell 200 can be used to cool and dissipate heat for the battery cell 200. In the heat exchange assembly of the disclosed embodiment, each battery cell can be assembled in the corresponding receiving space by plugging, and the surface of the battery cell around the side can be in contact with the side wall of the receiving space, thereby greatly increasing the effective heat dissipation area of ​​the battery cell, improving the overall heat dissipation performance, meeting the needs of super fast charging, high-power discharge, etc., and also helping to extend the overall service life of the battery and improve the safety of use.

[0043] In some embodiments, one of the first heat exchange plate 13 and the second heat exchange plate 14 is provided with a mounting groove 133 , and the other of the first heat exchange plate 13 and the second heat exchange plate 14 is embedded in the mounting groove 133 .

[0044] Specifically, the assembly grooves 133 may be provided on the first heat exchange plate 13, the number of the assembly grooves 133 may be the same as the number of the second heat exchange plate 14, and the plurality of assembly grooves 133 may be arranged at intervals along the extension direction of the first heat exchange plate 13. Each assembly groove 133 may penetrate the first heat exchange plate 13 along the thickness direction of the first heat exchange plate 13, and the notch of each assembly groove 133 may be located at the top side or the bottom side of the first heat exchange plate 13.

[0045] When assembling the heat exchange plate group 1, the second heat exchange plate 14 can be laterally embedded into the corresponding assembly groove 133 from the notch of each assembly groove 133, thereby facilitating the assembly of the first heat exchange plate 13 and the second heat exchange plate 14. After assembly, the limiting effect of the first heat exchange plate 13 and the second heat exchange plate 14 can also be enhanced, thereby improving the convenience of use.

[0046] In some other embodiments, the assembly groove 133 may also be provided on the second heat exchange plate 14 . In this case, the first heat exchange plate 13 may be embedded in the assembly groove 133 on the second heat exchange plate 14 .

[0047] In some embodiments, the first heat exchange plate 13 includes a plurality of sub-plates 131 and at least one connecting tube 132, the plurality of sub-plates 131 are arranged at intervals along the second direction (the extension direction of the first heat exchange plate 13), two adjacent sub-plates 131 are connected by a connecting tube 132, the width dimension of the connecting tube in the third direction is smaller than the width dimension of the sub-plate in the third direction, and the connecting tube 132 and the two adjacent sub-plates 131 form an assembly groove 133, and the third direction is perpendicular to the first direction and the second direction.

[0048] For example, Figure 2 As shown, the first heat exchange plate 13 may include four sub-plates 131, and the four sub-plates 131 may be arranged along the extension direction of the first heat exchange plate 13 ( Figure 2 There may be three connecting tubes 132, and the three connecting tubes 132 may be connected between two adjacent sub-plates 131 in a one-to-one correspondence.

[0049] like Figure 3 As shown, each sub-plate 131 may include an end plate 1311 located on the left or right side of the sub-plate 131, the connecting tube 132 may extend along the left-right direction, the left end of the connecting tube 132 may be connected to the right end plate 1311 of the left sub-plate 131, and the right end of the connecting tube 132 may be connected to the left end plate 1311 of the right sub-plate 131.

[0050] The spacing space between the two end plates 1311 located on the upper side of the connecting tube 132 can form an assembly groove 133. In some other embodiments, the spacing space between the two end plates 1311 located on the lower side of the connecting tube 132 can also form an assembly groove 133.

[0051] The third direction may be the up-down direction, in which the diameter of the connecting tube 132 is smaller than the width of the corresponding sub-plate 131. Therefore, when the connecting tube 132 is connected between two sub-plates 131, due to the size difference, a gap-like space is formed between the connecting tube 132 and two adjacent sub-plates 131, and the space is the above-mentioned assembly groove 133, thereby facilitating the molding arrangement of the assembly groove 133.

[0052] In some embodiments, Figure 3 As shown, the connecting pipe 132 is connected to the middle of the two sub-plates 131 in the vertical direction. The connecting pipe 132 divides the interval between the two sub-plates 131 into two assembly grooves 133 in the vertical direction. The two assembly grooves 133 are arranged roughly mirror-symmetrically with respect to the connecting pipe 132 in the vertical direction. Figure 1 As shown, a second heat exchange plate 14 can be embedded in each of the two assembly grooves 133. This can further enhance the overall structural stability of the heat exchange plate assembly 1.

[0053] In some other embodiments, the connecting pipe 132 may also be connected between the top sides or bottom sides of the two end plates 1311. In this case, there is only one assembly groove 133.

[0054] In some embodiments, the heat exchange assembly includes a tube group 2 , which is connected to the first heat exchange plate 13 and the second heat exchange plate 14 , and is used to transport heat exchange medium into the first heat exchange plate 13 and the second heat exchange plate 14 .

[0055] For example, the tube group 2 is connected to the heat exchange plate group 1 and is in communication with the cavities of the first heat exchange plate 13 and the second heat exchange plate 14, and the tube group 2 is used to transport the heat exchange medium into the channel to cool the battery cell 200. For example, the tube group 2 may include a plurality of pipes, and different parts of the heat exchange plate group 1 may be connected through corresponding pipes, thereby connecting the cavities at different positions of the heat exchange plate group 1, and facilitating the flow of the heat exchange medium in the heat exchange plate group 1. The heat exchange medium may specifically be a liquid such as ethylene glycol or a medium such as a cooling gas that can take away heat.

[0056] In some embodiments, the tube group 2 includes a first tube 23 and a second tube 24, the first tube 23 extends along the second direction, the second tube 24 extends along the first direction, multiple first heat exchange plates 13 are connected to the first tube 23, multiple second heat exchange plates 14 are connected to the second tube 24, the first tube 23 and the second tube 24 are arranged to intersect, and the first tube 23 and the second tube 24 are connected.

[0057] For example, Figure 1 As shown, the first tube 23 and the second tube 24 can both be round tubes. In some other embodiments, the first tube 23 and the second tube 24 can also be square tubes, special-shaped tubes, etc.

[0058] The first tube 23 may extend in the front-to-back direction, may be located at the right end of the plurality of first heat exchange plates 13 , and may pass through the plurality of first heat exchange plates 13 at the same time, so that the channels in the plurality of first heat exchange plates 13 may be connected through the first tube 23 .

[0059] The second tube 24 may extend in the left-right direction, may be located at the rear end of the plurality of second heat exchange plates 14 , and may pass through the plurality of second heat exchange plates 14 at the same time, so that the channels in the plurality of second heat exchange plates 14 may be connected via the second tube 24 .

[0060] The rear end of the first tube 23 and the right end of the second tube 24 can be connected. Therefore, when in use, the heat exchange medium can be introduced into all the first heat exchange plates 13 and all the second heat exchange plates 14 by introducing the heat exchange medium into one of the first tube 23 and the second tube 24, which facilitates the introduction of the heat exchange medium.

[0061] In some embodiments, when each first heat exchange plate 13 is provided with two assembly grooves 133, at this time, the plurality of second heat exchange plates 14 can be arranged in two rows in the vertical direction, and each row of second heat exchange plates 14 can be connected in series through a second tube 24, that is, the second tube 24 can be provided with two. Figure 1 As shown, the two second tubes 24 can be arranged in parallel and spaced apart in the up-down direction, and the right ends of the two second tubes 24 can be connected to the first tube 23 , thereby realizing the series connection of all the second heat exchange plates 14 .

[0062] In some embodiments, the first tube is located at the end of the plurality of first heat exchange plates 13, the second tube is located at the end of the plurality of second heat exchange plates 14, and one end of the first tube is connected to one end of the second tube. Figure 1 As shown, the first tube can be located at the right end of the plurality of first heat exchange plates 13, the second tube can be located at the rear end of the plurality of second heat exchange plates 14, and the rear end of the first tube can be arranged to intersect and communicate with the left end of the second tube. This is conducive to the heat exchange medium flowing from one end of the first heat exchange plate 13 or the second heat exchange plate 14 to the other end, thereby fully ensuring the balance of the heat exchange medium distribution and improving the heat exchange effect.

[0063] In some embodiments, Figure 1 As shown, the pipe group 2 includes a valve 25, which is arranged at the connection between the first pipe 23 and the second pipe 24. The valve 25 can realize the opening and closing control of the corresponding pipeline (the first pipe 23, the second pipe 24) or the adjustment of the heat exchange medium delivery amount, so as to realize the regulation of the cooling process.

[0064] Optionally, the valve 25 may be a three-way valve, a four-way valve, etc. The specific type of the valve 25 may be selected according to the number of pipelines at the connection.

The first heat exchange plate 13 may be provided with interfaces 15 at both ends of its extension direction, and the second heat exchange plate 14 may also be provided with interfaces 15 at both ends of its extension direction. The design of the interface 15 being provided at the end is conducive to the heat exchange medium flowing from one end of the plate body 12 to the other end.

[0066] It should be noted that the first heat exchange plate 13 and the second heat exchange plate 14 are both long plates and can be referred to as plate bodies 12. Each plate body 12 can be provided with an interface 15 on two opposite sides in its thickness direction to facilitate the connection between the plate body 12 and two adjacent plate bodies 12.

[0067] In other embodiments, along the direction of the spaced arrangement of the plurality of plates 12, the plate 12 at the end may only be provided with the interface 15 on the inner side (the side facing the other plate 12), and no interface 15 may be provided on the outer side of the plate 12. In this case, the pipe group 2 may be directly connected to the plate 12 at the end. That is, the arrangement, quantity and position of the interface 15 may be selectively adjusted according to actual needs.

[0068] In some embodiments, the tube group 2 includes a plurality of transfer tubes 28, which are disposed between two adjacent first heat exchange plates 13 or two adjacent second heat exchange plates 14, one end of each transfer tube 28 being connected to an interface 15 of one of the two adjacent first heat exchange plates 13 or two adjacent second heat exchange plates 14, and the other end being connected to an interface 15 of the other of the two adjacent first heat exchange plates 13 or two adjacent second heat exchange plates 14.

[0069] like Figure 1 As shown, the transfer tube 28 can be a short round tube, and the transfer tube 28 can be connected between two adjacent first heat exchange plates 13, that is, the front end of the transfer tube 28 can be sealed and connected to the corresponding interface 15 of the front first heat exchange plate 13, and the rear end of the transfer tube 28 can be sealed and connected to the corresponding interface 15 of the rear first heat exchange plate 13.

[0076] When in use, the heat exchange medium can be transported to the first tube 23 and the second tube 24 of the liquid inlet tube group 21 through the liquid inlet port 26, and then the heat exchange medium in the first tube 23 of the liquid inlet tube group 21 can flow into each first heat exchange plate 13, and then can be converged into the first tube 23 of the liquid return tube group 22 and discharged through the liquid outlet 27.
