Problems solved by technology

③The heat dissipation technology adopted is relatively backward. The currently known permanent magnetic coupling drive or speed regulation technology of the transmission shaft and its products mainly use traditional blade-type radiators and water cooling systems for heat dissipation. Not only the heat dissipation efficiency is not high, but due to the structure Limitation, there are many heat-dissipating components that cannot be dealt with or dealt with in place, so the power capacity per unit volume of the product cannot be too large
