A heat exchange structure 200 of a battery according to an embodiment of the present utility model is described below with reference to fig. 1 to 10.

As shown in fig. 1 to 9, a heat exchange structure 200 of a battery according to an embodiment of the present utility model includes: the liquid cooling tube 10, the heating element 20, the heat exchange tube 30 and the heat conducting structure 40.

The liquid cooling pipe 10 is internally provided with a heat exchange medium, the heating element 20 is suitable for heating the heat exchange pipe 30, the heat exchange pipe 30 is suitable for exchanging heat with the busbar 101 of the battery 100, a heat exchange space for flowing the heat exchange medium is formed in the heat exchange pipe 30, the heat exchange space is provided with a liquid inlet 31 and a liquid outlet 32, the liquid inlet 31 and the liquid outlet 32 are respectively communicated with two ends of the liquid cooling pipe 10, the heat conducting structure 40 is positioned between the heat exchange pipe 30 and the busbar 101, and the cross section area of the heat conducting structure 40 in the distribution direction of the heat exchange pipe 30 and the busbar 101 is in a descending trend in the direction from the liquid inlet 31 to the liquid outlet 32, so that the heat exchange pipe 30 extends obliquely relative to the busbar 101.

Therefore, the heat conducting structure 40 arranged between the heat exchange tube 30 and the busbar 101 can transfer the heat generated by the battery 100 into the heat exchange tube 30, so that the heat exchange medium in the heat exchange tube 30 can absorb the heat to dissipate the heat of the battery 100, the heat exchange medium in the heat exchange tube 30 can reenter the liquid cooling tube 10 through the liquid outlet 32, and meanwhile, the new heat exchange medium can be input into the heat exchange space through the liquid inlet 31 by the liquid cooling tube 10, so that the circulation of the heat exchange medium is completed, and when the battery 100 needs to be heated, the heating element 20 heats the heat exchange tube 30, and the heat is transferred to the battery 100 again through the heat conducting structure 40, so that the battery 100 is heated.

Further, the cross-sectional areas of the heat conductive structures 40 in the vertical direction are not parallel to the distribution directions of the heat exchange tubes 30 and the bus bars 101, but are in a descending trend, so that the heat exchange tubes 30 are not parallel to the bus bars 101, and the heat exchange medium in the heat exchange space can exchange heat better.

For example, the heat conducting structure 40 disposed on the bus bar 101 of the battery 100 may be configured as a heat conducting structural adhesive, and the heat exchanging tube 30 is disposed on a side of the heat conducting structural adhesive facing away from the bus bar 101, where the heat exchanging tube 30 can exchange heat to the battery 100 through the heat conducting structural adhesive, and the cross-sectional area of the heat conducting structural adhesive in the distribution direction of the heat exchanging tube 30 and the bus bar 101 is a decreasing trend, so that the plane of the heat exchanging tube 30 intersects with the plane of the bus bar 101, i.e., the heat exchanging tube 30 may incline to a certain degree with respect to the bus bar 101, and the heat exchanging medium in the heat exchanging tube 30 has two states of liquid state and gas state, and the heat exchanging tube 30 in an inclined state can make the gaseous heat exchanging medium more easily discharged from the heat exchanging tube 30.

Further, when the sectional area of the heat-conducting structural adhesive is in a descending trend, the sectional area of the heat-conducting structural adhesive is gradually reduced, so that the heat exchange tube 30 can be better attached to the heat-conducting structural adhesive, the heat exchange tube 30 can exchange heat with the battery 100 better, and the other heat-conducting structural adhesive is in a step-like descending manner, so that the inclination of the heat exchange tube 30 relative to the busbar 101 is higher, and heat exchange media in different states can be separated better.

Therefore, after the heat exchange tube 30 is obliquely arranged, the heat exchange medium in the heat exchange space is also obliquely arranged, so that the liquid heat exchange medium after heat exchange can enter the liquid cooling tube 10 through the liquid outlet 32, and the gaseous heat exchange medium can enter the liquid cooling tube 10 through the liquid inlet 31.

According to the heat exchange structure 200 of the battery, according to the embodiment of the utility model, a heat exchange medium enters the heat exchange tube 30 through the liquid cooling tube 10, a heat conduction structure 40 is further arranged between the heat exchange tube 30 and the busbar 101, and the heat conduction structure 40 can form a certain inclination relative to the busbar 101, so that the liquid inlet 31 and the liquid outlet 32 of the heat exchange tube 30 form a height difference, the gas-liquid separation is realized after the phase change of the heat exchange medium is facilitated, the circulation of the heat exchange medium is accelerated, the heat exchange efficiency is improved, when the battery 100 needs to exchange heat, heat is transferred between the battery 100 and the heat exchange medium through the heat conduction structure 40, and meanwhile, the heat exchange structure 200 has the advantages of small required space, simple structure, difficult failure and high heat exchange efficiency.

It should be noted that, after the heat exchange tube 30 is provided with the bent tube section 33, the liquid inlet 31 or the liquid outlet 32 can be arranged at one side of the bent tube section 33 far away from the horizontal tube section 34, so that the liquid inlet 31 and the liquid outlet 32 can form a height difference, and meanwhile, the liquid inlet 31, the liquid outlet 32 and the horizontal tube section 34 can also form a height difference, so that gas-liquid separation of the heat exchange medium after phase change is completed can be facilitated, and circulation of the heat exchange medium is accelerated, and heat exchange efficiency is further improved.

Therefore, the heat exchange tube 30 can facilitate the gas-liquid separation of the heat exchange medium after the bending tube section 33 is arranged, and the circulation of the heat exchange medium is faster, so that the heat exchange efficiency is improved.

In some embodiments, as shown in fig. 5, the bending tube section 33 includes a first bending tube section 331, and an end of the first bending tube section 331 communicating with the liquid cooling tube 10 is configured as the liquid inlet 31.

Therefore, when the bending section is only the first bending section 331, the heat exchange tube 30 is configured in an L shape, and the liquid inlet 31 is disposed at the connection between the first bending section 331 and the liquid cooling tube 10, so that the liquid inlet 31 and the liquid outlet 32 can form a height difference, so that the heat exchange medium can flow out of the heat exchange tube 30 more easily.

In some embodiments, as shown in fig. 6, the bending tube section 33 includes a first bending tube section 331 and a second bending tube section 332, the first bending tube section 331 and the second bending tube section 332 are respectively connected to two ends of the horizontal tube section 34, and one ends of the first bending tube section 331 and the second bending tube section 332, which are respectively connected to the liquid cooling tube 10, are configured as the liquid inlet 31 and the liquid outlet 32.

Therefore, after the heat exchange tube 30 constructed as the rectangular straight tube is attached to the heat conducting structure 40, the circulation of the heat exchange medium can be accelerated, so that the heat exchange efficiency of the heat exchange structure 200 is improved.
