AI Technical Summary
The poor heat dissipation efficiency of the sealed electrical dry chamber affects the system's operating efficiency.
A dual water-cooling system is installed in the electrical dry compartment, including a main water pump, an auxiliary water pump, a water tank, a water-cooling plate, and a solenoid valve. The working status of the main water pump and the auxiliary water pump is controlled by a single two-way solenoid valve, which can switch between the dual water-cooling system and the single water-cooling system to improve heat dissipation efficiency.
It enables flexible adjustment based on heat dissipation needs, reduces energy loss, improves the heat dissipation efficiency of the electrical dry compartment, and avoids the problems caused by the water pump working alone at high intensity.
