The roughness of the contact surface between the direct cooling battery pack liquid cooling plate and the battery pack can be increased by using appropriate surface treatment techniques, such as sandblasting, chemical etching or laser texturing. This roughening helps create more microscopic contact points on the contact surface, thereby improving heat transfer efficiency.
Using efficient sealing materials and techniques, such as O-rings, sealants or welding, can ensure a tight seal between the direct cooling battery pack liquid cooling plate and the battery pack. At the same time, choose an appropriate fixing method, such as bolt fixing, snap fixing or welding fixing, to maintain the stability and consistency of the contact surface.
Applying thermal interface materials (TIM), such as thermally conductive silicone sheets, thermally conductive gels, or thermally conductive grease, between the direct cooling battery pack liquid cooling plate and the battery pack can fill the tiny gaps between the contact surfaces and reduce thermal resistance. These materials have high thermal conductivity and can significantly improve heat transfer efficiency.
By applying appropriate pressure, the contact between the direct cooling battery pack liquid cooling plate and the battery pack can be made closer. This can be achieved by properly designed fastening structures or by using pressure sensors and control systems. Proper pressure helps ensure uniformity and stability of the contact surface.
During battery pack operation, it is critical to closely monitor and control temperature. By integrating temperature sensors and cooling systems, the temperature of the battery pack can be monitored in real time and adjusted as needed. This helps ensure the direct cooling battery pack liquid cooling plate always maintains close contact with the battery pack, thereby optimizing heat transfer.
The use of precise assembly processes, such as automated assembly lines or precision positioning equipment, can ensure the alignment and positioning accuracy of the direct cooling battery pack liquid cooling plate and the battery pack during the assembly process. This helps reduce assembly errors and improves the tightness and consistency of the contact surface.
Regular maintenance and inspection of the direct cooling battery pack liquid cooling plate and battery pack, including cleaning the contact surface, checking the sealing performance and the looseness of fasteners, can ensure that they always maintain good contact. This helps extend the life of the equipment and optimizes heat transfer performance.
