Description

Technical Field

[0001] The present application belongs to the technical field of liquid cooling plates, and in particular to titanium-aluminum composite liquid cooling plates. Background Art

[0002] The liquid cooling plate can effectively remove the large amount of heat generated by the battery during the charging and discharging process, maintain the stability of the battery temperature, and avoid the adverse effects of excessive temperature on the performance and life of the battery. For example, overheating may cause the battery capacity to decay faster, the internal resistance to increase, and even thermal runaway and other safety issues. Timely heat dissipation through the liquid cooling plate can ensure that the battery is in a suitable operating temperature range for a long time, improving the reliability and durability of the battery.

[0003] In the existing market, two kinds of aluminum composite materials are generally used to make runner plates. One kind of aluminum material is used to make the flat plate, and the runner plate is made of two different aluminum materials. The base material ensures the strength of the liquid cooling plate, and the composite layer of aluminum acts as a welding agent for the flat plate and the runner plate. The composite layer is heated and melted, and the flat plate and the runner plate are bonded into a whole to form a liquid cooling plate with a stable structure. However, the strength of aluminum is relatively weak and cannot bear heavy battery cells. After bearing a large weight, the liquid cooling plate will deform, resulting in a reduction in the contact area with the battery cell and a reduction in its heat dissipation capacity. Therefore, the existing technology reinforces its structure by adding a reinforcing plate. However, after the reinforcement is added, the overall weight is relatively large, and there are greater requirements for its supporting structure and transportation, which increases the cost.

[0036] The operating principle of the utility model is now described as follows:

[0037] When the present application is used, a liquid cooling plate is made of a titanium-aluminum composite plate. The composite aluminum layer 6 on the flow channel plate 2 will melt during the brazing process, and the entire liquid cooling plate will be bonded into a whole. The flat plate 1 and the flow channel plate 2 are connected with a first substrate titanium layer 4 and a second substrate titanium layer 7, which solves the problems of poor load-bearing capacity and easy deformation of traditional aluminum liquid cooling plates.

When the liquid cooling plate needs to be stacked, the two liquid cooling plates are stably connected up and down through the matching plug-in connection of the plug-in column 10 and the plug-in tube 11. In the process of plug-in assembly, the reset pull plate 17 is pulled back and the L-shaped baffle plate 21 is pulled down. The reset pull plate 17 pulls the locking rod 15 out of the plug-in tube 11. At this time, the L-shaped baffle plate 2 The vertical portion of 1 is arranged at the front side of the reset pull plate 17, and then the L-shaped baffle 21 is loosened, and the L-shaped baffle 21 is blocked at the side of the reset pull plate 17 under the action of the push spring 23 to limit the locking rod 15. After the connection between the plug-in column 10 and the plug-in tube 11 is completed, the L-shaped baffle 21 is pulled down again, and the reset pull plate 17 moves back under the action of the reset spring 18, so that the locking rod 15 is inserted into the locking hole 16, so as to realize the stable connection between the plug-in column 10 and the plug-in tube 11, ensure the structural stability, and realize the non-contact stable stacking and transportation of multiple liquid cooling plates, which is convenient for use.
