Design and Research of Cooling System for Valve Based Electronics

The valve base electronics is the core equipment of a high-voltage direct current (HVDC) transmission system, which has the problem of high operating heat. To achieve its good ventilation and cooling function, the functions and hardware configuration of the valve base electronics were first explained. Then, a design method for a heat dissipation system was proposed, including the design of screen cabinet cooling ducts, selection of heat dissipation fans, and design of cooling modules. Finally, building upon the engineering valve-based electronic equipment, the effectiveness of the cooling system design was verified by testing the air volume of the cooling module and the temperature rise of the screen cabinet. Experiments have shown that this scheme can achieve temperature rise control of valve-based electronic equipment cabinets and chassis within 10K, enabling valve base electronics to operate within a suitable temperature range.
