In the design of Direct Cooling Battery Pack Liquid Cooling Plate, it is crucial to ensure that the coolant does not leak. A reliable sealing structure can not only ensure the normal operation of the battery pack, but also prevent potential safety hazards.
First of all, the selection of sealing materials is the key. It is necessary to select materials with good corrosion resistance, high temperature resistance and elasticity, such as high-quality rubber sealing rings or high-performance sealants. These materials can withstand the chemical erosion of the coolant and the impact of temperature changes during long-term use, while maintaining good sealing performance.
Secondly, the form of the sealing structure is also very important. Common ones include plane seals, O-ring seals and groove seals. Plane seals are relatively simple, but have high requirements for the flatness and roughness of the contact surface; O-ring seals have better adaptability, but attention should be paid to the reasonable design of the size and compression of the O-ring; groove seals can provide better sealing effects, but the processing difficulty and cost are also relatively high. In actual design, it is necessary to select a suitable sealing form according to the specific structure and working conditions of the liquid cooling plate.
Furthermore, the treatment of the sealing contact surface cannot be ignored. The contact surface should be finely processed to ensure that the surface is flat and smooth without scratches, burrs and other defects. This can reduce the generation of tiny gaps and improve the sealing effect. At the same time, during the installation process, it is necessary to ensure the cleanliness between the seal and the contact surface to avoid impurities affecting the sealing performance.
In addition, a reasonable fastening method is also an important link to ensure sealing. Through appropriate bolt tightening force or clamp pressure, the seal is evenly compressed to achieve a good sealing state. However, the fastening force should not be too large to avoid damaging the seal or causing deformation of the liquid cooling plate.
Finally, strict sealing performance testing is required. After the production of the liquid cooling plate is completed, pressure testing, leakage detection and other tests should be carried out to simulate actual working conditions and verify the reliability of the sealing structure. For the problems found, timely improvements and optimizations should be made.
In short, the design of the sealing structure of the Direct Cooling Battery Pack Liquid Cooling Plate requires comprehensive consideration of sealing materials, structural forms, contact surface treatment, fastening methods and performance testing. Only by careful design and strict control of each link can we effectively ensure that the coolant will not leak and provide reliable protection for the stable operation of the direct cooling battery pack.
