AI Technical Summary

Technical Problem

Existing water electrolysis hydrogen production devices generate a lot of heat during the electrolysis process, and the terminals heat up quickly and lack heat dissipation devices, which leads to severe overheating of the terminals and damage to the electrolyzer.

Method used

An electrolytic cell was designed, comprising a first heat dissipation assembly consisting of an annular heat-conducting plate and a heat rod, which dissipates heat through the evaporation and condensation cycle of liquid ammonia, and a second heat dissipation assembly that combines a support block and a spacer assembly to reduce the mutual attraction of the terminals, and a water pump and water pipe to cool the top cover.

Benefits of technology

It effectively reduces the risk of overheating and damage to the terminals, improves the utilization rate and safety of the electrolytic cell, and at the same time reduces the overall temperature of the electrolytic cell through multiple heat dissipation measures, thus extending the equipment life.
