AI Technical Summary
Existing coaxial loads have poor waterproof performance in outdoor environments, resulting in high maintenance costs.
By introducing a combination structure of cover plate, transition plate, multi-layer sealing ring and threaded parts into the coaxial load, the sealing performance is enhanced, and water guide grooves are set on the transition plate to guide water flow and improve waterproof performance.
Without replacing the radiator and inner cylinder, it significantly improves the waterproof performance of coaxial loads, reduces maintenance costs, and enhances heat dissipation.
