Fig. 1 is a schematic structural view of an embodiment of a cooling assembly according to an embodiment of the present utility model. As shown in fig. 1, the cooling assembly 100 includes a plurality of cooling tubes 110, and the plurality of cooling tubes 110 are sequentially spaced apart along the second direction Y. The cooling pipe 110 may circulate a cooling liquid therein to cool the cooling pipe 110. The plurality of cooling pipes 110 of the cooling assembly 100 may be disposed between the battery cells (not shown) of the battery module (not shown) to cool the battery cells of the battery module.

As shown in fig. 2 and 4, the cooling pipe 110 includes a connection pipe section 111, a first cooling pipe section 112, and a second cooling pipe section 113, the first cooling pipe section 112 and the second cooling pipe section 113 extending in a first direction X, respectively, one end of the first cooling pipe section 112 communicating with one end of the connection pipe section 111, one end of the first cooling pipe section 112 remote from the connection pipe section 111 having an inlet 1120; one end of the second cooling tube segment 113 communicates with the other end of the connecting tube segment 111, and the other end of the second cooling tube segment 113 has an outlet 1135.

The cooling liquid can enter the cooling pipe 110 from the inlet 1120 of the cooling pipe 110 and flow through the first cooling pipe segment 112, the connecting pipe segment 111 and the second cooling pipe segment 113 in sequence, and then flow out from the outlet 1135 of the cooling pipe 110, so as to realize the purpose that the cooling liquid circularly flows in the cooling pipe 110 to cool the cooling pipe 110.

With continued reference to fig. 3 and 4, the second cooling tube segment 113 and the first cooling tube segment 112 are disposed in parallel and spaced apart relation along the second direction Y, and an installation space 1100 for installing the battery cell is formed between the first cooling tube segment 112 and the second cooling tube segment 113. Thus, the battery cell of the battery module may be placed in the installation space 1100 between the first and second cooling pipe sections 112 and 113, and heat generated from the battery cell may be transferred to the cooling pipe 110 and removed by the cooling liquid in the cooling pipe 110.

In some embodiments, the inlet 1120 of the first cooling pipe segment 112 and the outlet 1135 of the second cooling pipe segment 113 are sequentially spaced apart along the second direction Y, and the inlet 1120 of the first cooling pipe segment 112 and the outlet 1135 of the second cooling pipe segment 113 have different heights in the third direction Z. Wherein the second direction Y and the first direction X are perpendicular to the third direction Z, respectively.

The cooling pipe 110 provided in the embodiment of the present utility model is sequentially and alternately distributed along the second direction Y by making the inlet 1120 of the first cooling pipe segment 112 far from the end of the connecting pipe segment 111 and the outlet 1135 of the second cooling pipe segment 113 far from the end of the connecting pipe segment 111, and making the inlet 1120 of the first cooling pipe segment 112 and the outlet 1135 of the second cooling pipe segment 113 have different heights in the third direction Z. The plurality of cooling pipes 110 may be sequentially spaced apart in the second direction Y such that the inlet 1120 and the outlet 1135 of each cooling pipe 110 are positioned at the same end of the cooling pipe 110 in the first direction X, and the connection pipe section 111 of each cooling pipe 110 is positioned at the other end of the cooling pipe 110 in the first direction X, and then communicates with the inlet 1120 of each cooling pipe 110 through the liquid supply line 120 (shown in fig. 1) and communicates with the outlet 1135 of each cooling pipe 110 through the liquid return line 130 (shown in fig. 1) to constitute the cooling assembly 100.

Therefore, the liquid supply pipeline 120 and the liquid return pipeline 130 are located at the same end of the cooling assembly 100 along the first direction X, and the liquid supply pipeline 120 and the liquid return pipeline 130 can be arranged in parallel along the third direction Z, so that the installation space 1100 occupied by the liquid supply pipeline 120 and the liquid return pipeline 130 is smaller, and the liquid supply pipeline and the liquid return pipeline 130 can be more conveniently arranged in the battery module.

In some embodiments, as shown in fig. 3 and 4, an end of the first cooling tube segment 112 remote from the connecting tube segment 111 is provided with a first connecting portion 1122, and an inlet 1120 of the first cooling tube segment 112 extends through the first connecting portion 1122 in the second direction Y. By passing the inlet 1120 of the first cooling pipe segment 112 through the first connection portion 1122 in the second direction Y, the liquid supply line 120 can be more conveniently communicated with the inlet 1120 of the first cooling pipe segment 112.

The first connection portion 1122 may be provided with a first escape opening 1124. In the second direction Y, the first relief opening 1124 of the first connection 1122 at least partially overlaps the outlet 1135. Thus, the first avoidance opening 1124 of the first connection portion 1122 can avoid the liquid return line 130, so that the liquid return line 130 can be closer to the second cooling pipe section 113, thereby further reducing the installation space 1100 occupied by the liquid return line 130.

With continued reference to fig. 3 and 4, a first connection protrusion 1123 may be provided protruding at least one side of the first connection portion 1122 in the second direction Y, and the inlet 1120 penetrates the first connection protrusion 1123 in the second direction Y. Thus, the liquid supply pipe 120 may be fitted over the first connecting protrusion 1123, so that the liquid supply pipe 120 communicates with the inlet 1120 of the first cooling pipe section 112.

The first connection protrusions 1123 may be respectively protruded at two sides of the first connection portion 1122 along the second direction Y, so that the liquid supply pipes 120 located at two sides of the first connection portion 1122 along the second direction Y can be conveniently communicated with the inlet 1120 of the first connection portion 1122.

Specifically, the first connection portion 1122 is provided with a cylindrical first connection protrusion 1123 protruding on both sides in the second direction Y, respectively. The first coupling protrusion 1123 extends in the second direction Y. The inlet 1120 of the first cooling pipe segment 112 is a circular hole and penetrates the first connecting protrusions 1123 at both sides of the first connecting portion 1122 in the second direction Y.

The supply line 120 includes a supply tube segment 121 positioned between the inlets 1120 of adjacent two of the cooling tubes 110. The inlets 1120 of two adjacent cooling pipes 110 are communicated through the liquid supply pipe section 121. The two ends of the liquid supply pipe section 121 are respectively sleeved on the first connecting protrusions 1123 of the two adjacent first cooling pipe sections 112, which face each other, so as to communicate the inlets 1120 of the two adjacent first cooling pipe sections 112. When the inlets 1120 of any two adjacent first cooling pipe sections 112 are communicated through the liquid supply pipe section 121, a liquid supply pipeline 120 communicated with each inlet 1120 is formed.

Wherein the liquid supply pipe section 121 extends in the second direction Y. The first supply line 120 may be a first bellows. The first bellows may be a nylon bellows. The liquid supply pipe section 121 and the first connecting protrusion 1123 may be expanded to improve the connection stability of the liquid supply pipe section 121 and the first connecting protrusion 1123. Of course, the liquid supply pipe 121 and the first connecting protrusion 1123 may be connected by adhesion, welding, or the like.

It will be appreciated that the communication between the liquid supply pipe section 121 and the inlets 1120 of the first cooling pipe sections 112 is not limited to the above embodiments, and in fact, two ends of the liquid supply pipe section 121 may be inserted into the inlets 1120 of two adjacent first cooling pipe sections 112, respectively, so as to communicate the inlets 1120 of two adjacent first cooling pipe sections 112. Alternatively, it is also possible to insert one end of the liquid supply pipe section 121 into the inlet 1120 of one of the adjacent two first cooling pipe sections 112 and to fit the other end of the liquid supply pipe section 121 over the first connection protrusion 1123 of the other one of the adjacent two first cooling pipe sections 112 to communicate the inlets 1120 of the adjacent two first cooling pipe sections 112.

In other embodiments, the output end of the liquid supply line 120 may be inserted directly into the inlet 1120 of the first cooling pipe segment 112 to communicate the liquid supply line 120 with the inlet 1120 of the first cooling pipe segment 112. Specifically, the liquid supply pipeline 120 may extend along the second direction Y, and the liquid supply pipeline 120 includes a plurality of output ends sequentially distributed along the second direction Y, where the number of the output ends is equal to that of the inlets 1120, and the output ends are connected in a one-to-one correspondence manner, so as to communicate the liquid supply pipeline 120 with the plurality of inlets 1120. In this case, the inlet 1120 of the first cooling pipe segment 112 may be directed toward the direction in which the first cooling pipe segment 112 is away from the connecting pipe segment 111 or other direction.

In some embodiments, as shown in fig. 3 and 4, an end of the second cooling tube segment 113 remote from the connecting tube segment 111 is provided with a second connection portion 1132, and an outlet 1135 of the second cooling tube segment 113 extends through the second connection portion 1132 in the second direction Y. By passing the outlet 1135 of the second cooling pipe segment 113 through the second connection 1132 in the second direction Y, the return line 130 can be more conveniently communicated with the outlet 1135 of the second cooling pipe segment 113.

The second connection portion 1132 may be provided with a second avoidance port 1134. In the second direction Y, the second relief port 1134 at least partially overlaps the inlet port 1120. Therefore, the second avoidance port 1134 can avoid the liquid supply pipe section 121 of the liquid supply pipeline 120, so that the liquid supply pipe section 121 of the liquid supply pipeline 120 can be closer to the first cooling pipe section 112, and the installation space 1100 occupied by the liquid supply pipeline 120 is further reduced.

With continued reference to fig. 3 and 4, a second connection protrusion 1133 may be provided protruding at least one side of the second connection portion 1132 in the second direction Y, and the outlet 1135 penetrates the second connection protrusion 1133 in the second direction Y. Thus, the return line 130 may be sleeved on the second connection protrusion 1133, so that the return line 130 communicates with the outlet 1135 of the second cooling pipe segment 113.

The second connection protrusions 1133 may be respectively protruding on two sides of the second connection portion 1132 along the second direction Y, so that the liquid return pipes 130 located on two sides of the second connection portion 1132 along the second direction Y can be conveniently communicated with the outlet 1135 of the second connection portion 1132.

Specifically, the second connection portion 1132 is respectively provided with a cylindrical second connection protrusion 1133 protruding from both sides thereof in the second direction Y. The second coupling protrusion 1133 extends in the second direction Y. The outlet 1135 of the second cooling pipe segment 113 is a circular hole, and penetrates the second connection protrusions 1133 at both sides of the second connection portion 1132 along the second direction Y.

The return line 130 includes a return line segment 131 between the outlets 1135 of adjacent two of the cooling tubes 110. The outlets 1135 of two adjacent cooling pipes 110 are communicated through the liquid return pipe segment 131. The two ends of the liquid return pipe segment 131 are respectively sleeved on the second connecting protrusions 1133 of the two adjacent second cooling pipe segments 113, which face each other, so as to communicate the outlets 1135 of the two adjacent second cooling pipe segments 113. When the outlets 1135 of any two adjacent second cooling pipe sections 113 are all communicated through the liquid return pipe section 131, a liquid return pipeline 130 communicated with each outlet 1135 is formed.

Wherein the liquid return pipe segment 131 extends along the second direction Y. The return pipe segment 131 may be a second bellows. The second bellows may be a nylon bellows. The liquid return pipe section 131 and the second connecting protrusion 1133 can be connected in an expanded mode, so that the connection stability of the liquid return pipe section 131 and the second connecting protrusion 1133 is improved. Of course, the liquid return pipe 131 and the second connecting protrusion 1133 may be connected by adhesion, welding, or the like.

It is to be understood that the communication manner between the liquid return pipe section 131 and the outlets 1135 of the second cooling pipe sections 113 is not limited to the above embodiments, and in fact, two ends of the liquid return pipe section 131 may be inserted into the outlets 1135 of two adjacent second cooling pipe sections 113, respectively, to communicate the outlets 1135 of two adjacent second cooling pipe sections 113. Alternatively, one end of the liquid return pipe section 131 may be inserted into the outlet 1135 of one second cooling pipe section 113 of the adjacent two second cooling pipe sections 113, and the other end of the liquid return pipe section 131 may be sleeved on the second connection protrusion 1133 of the other second cooling pipe section 113 of the adjacent two second cooling pipe sections 113 to communicate with the outlets 1135 of the adjacent two second cooling pipe sections 113.

In other embodiments, the input end of the return line 130 may also be inserted directly into the outlet 1135 of the second cooling pipe segment 113 to communicate the return line 130 with the outlet 1135 of the second cooling pipe segment 113. Specifically, the liquid return pipeline 130 may extend along the second direction Y, and the liquid return pipeline 130 includes a plurality of input ends sequentially distributed along the second direction Y, where the number of the input ends is equal to that of the outlets 1135, and the input ends are connected in a one-to-one correspondence manner, so as to communicate the liquid return pipeline 130 with the plurality of outlets 1135. In this case, the outlet 1135 of the second cooling tube segment 113 may be directed toward the direction of the second cooling tube segment 113 away from the connecting tube segment 111 or other direction.

It should be noted that, the first cooling pipe section 112 and the second cooling pipe section 113 may be configured according to the above embodiments, or only one of the first cooling pipe section 112 and the second cooling pipe section 113 may be configured according to the above embodiments, so long as the inlet 1120 of the first cooling pipe section 112 and the outlet 1135 of the second cooling pipe section 113 are sequentially spaced apart along the second direction Y, the inlet 1120 of the first cooling pipe section 112 and the outlet 1135 of the second cooling pipe section 113 have different heights in the third direction Z, and the liquid supply pipeline 120 and the liquid return pipeline 130 may be located at the same end of the cooling assembly 100 along the first direction X and may be arranged in parallel along the third direction Z.

In some embodiments, as shown in fig. 5 and 6, the first cooling tube segment 112 includes a first cooling channel 1121 extending in the first direction X, and a cooling fluid flows within the first cooling channel 1121 to cool the first cooling tube segment 112. The first cooling pipe segment 112 includes a plurality of first cooling channels 1121, where the plurality of first cooling channels 1121 are distributed sequentially along the third direction Z, and an inlet 1120 of the first cooling pipe segment 112 communicates with the plurality of first cooling channels 1121. By arranging the plurality of first cooling channels 1121 in the first cooling pipe section 112 and sequentially distributing the plurality of first cooling channels 1121 along the third direction Z, the cooling liquid in the first cooling pipe section 112 can be more uniformly distributed along the third direction Z, so as to improve the heat dissipation uniformity of the first cooling pipe section 112 in the third direction Z. At the same time, the first cooling pipe segment 112 can have high structural strength, and is not easy to be extruded to deform.

Likewise, the second cooling pipe segment 113 includes a second cooling channel 1131 extending in the first direction X, and a cooling liquid flows in the second cooling channel 1131 to cool the second cooling pipe segment 113. The second cooling pipe segment 113 includes a plurality of second cooling channels 1131, where the plurality of second cooling channels 1131 are distributed sequentially along the third direction Z, and an outlet 1135 of the second cooling pipe segment 113 is in communication with the plurality of first cooling channels 1121. Accordingly, the uniformity of heat dissipation of the second cooling pipe section 113 in the third direction Z is improved, and the second cooling pipe section 113 has high structural strength and is less likely to be deformed by extrusion.

It should be noted that, the first cooling channel 1121 in the first cooling pipe section 112 and the second cooling channel 1131 in the second cooling pipe section 113 may be both provided according to the above-described embodiment, or only the first cooling channel 1121 in the first cooling pipe section 112 may be provided according to the above-described embodiment, or only the second cooling channel 1131 in the second cooling pipe section 113 may be provided according to the above-described embodiment.

As shown in fig. 3 and 5, the first cooling tube segment 112 is a corrugated plate, and the corrugated direction of the first cooling tube segment 112 coincides with the first direction X. Thus, the contact area between the first cooling pipe section 112 and the battery cell can be increased, thereby improving the heat dissipation effect on the battery cell. Similarly, the second cooling pipe section 113 is a corrugated plate, and the corrugated direction of the second cooling pipe section 113 is consistent with the first direction X, so as to improve the heat dissipation effect of the second cooling pipe section 113 on the battery cell.

The shape of the first cooling pipe section 112 and the shape of the second cooling pipe section 113 may be the same or different, and may be specific according to the structure of the battery cell.

The embodiment of the utility model also provides a cooling assembly, which comprises a cooling pipe, and the specific structure of the cooling pipe refers to the embodiment, and because the cooling assembly adopts all the technical schemes of all the embodiments, the cooling assembly at least has all the beneficial effects brought by the technical schemes of the embodiments, and the details are not repeated here.

The cooling liquid enters the cooling pipe 110 from the liquid supply pipe 120, passes through the first cooling pipe segment 112, the connecting pipe segment 111 and the second cooling pipe segment 113 of the cooling pipe 110 in order, and flows into the liquid return pipe 130 from the outlet 1135 of the cooling pipe 110.

Wherein the inlet 1120 and the outlet 1135 of the plurality of cooling pipes 110 are located at the same end of the cooling pipe 110 along the first direction X. The liquid supply pipeline 120 is located at one end of the cooling pipe 110 provided with an inlet 1120, and the liquid supply pipeline 120 is communicated with the inlets 1120 of the plurality of cooling pipe 110. The liquid return pipeline 130 is positioned at one end of the cooling pipe 110 provided with an outlet 1135, and the liquid return pipeline 130 is communicated with the outlets 1135 of the plurality of cooling pipe 110.

Therefore, the liquid supply pipeline 120 and the liquid return pipeline 130 are located at the same end of the cooling assembly 100 along the first direction X, and the liquid supply pipeline 120 and the liquid return pipeline 130 can be arranged in parallel along the third direction Z, so that the installation space 1100 occupied by the liquid supply pipeline 120 and the liquid return pipeline 130 is smaller, and the liquid supply pipeline and the liquid return pipeline 130 can be more conveniently arranged in the battery module.

In some embodiments, the inlet 1120 and the outlet 1135 of each cooling tube 110 are sequentially distributed along the second direction Y. Thus, the plurality of first cooling pipe sections 112 and the plurality of second cooling pipe sections 113 of the cooling assembly 100 are sequentially arranged at intervals along the second direction Y, and when the battery cells are arranged between the adjacent first cooling pipe sections 112 and the second cooling pipe sections 113, the temperature neutralization of the battery cells can be achieved, that is, the cooling assembly 100 can have better and uniform heat dissipation efficiency for the plurality of battery cells.

Moreover, by sequentially distributing the inlet 1120 and the outlet 1135 of each cooling pipe 110 in the second direction Y, a larger distance can be maintained between the inlets 1120 of the adjacent two cooling pipe 110, so that the liquid supply pipe sections 121 connecting the inlets 1120 of the adjacent two cooling pipe 110 have a larger length, so that the assembly tolerance requirements of the liquid supply pipe sections 121 are lower, and the number of liquid supply pipe sections 121 is smaller.

Likewise, a larger distance can be maintained between the outlets 1135 of the adjacent two cooling pipes 110, so that the return pipe sections 131 connecting the outlets 1135 of the adjacent two cooling pipes 110 have a larger length, so that the assembly tolerance requirements of the return pipe sections 131 are lower, and the number of the return pipe sections 131 is smaller.

Of course, the plurality of cooling pipes 110 of the cooling module 100 may be distributed in other manners, so long as the liquid supply pipe 120 and the liquid return pipe 130 are located at the same end of the cooling module 100 along the first direction X, and the liquid supply pipe 120 and the liquid return pipe 130 can be disposed in parallel along the third direction Z.
