The invention relates to a heat dissipation control method, a charger, and a monitoring unit thereof and a memory. In the heat dissipation control method, the monitoring unit performs the steps of S10, acquiring an actual power value which the charger should output through communicating with a BMS module of an electric automobile; S20, equally dividing the actual power value according to the number of power modules in the charger, and controlling each power module to output power according to the mean value; S30, determining a speed value of an external fan according to the mean value so as toenable the speed value to be in positive correlation with the actual power value or the mean value; and S40, adjusting the speed of the external fan according to the determined speed value. By implementing the technical scheme of the invention, the external fan can adjust the speed and operate according to the actual power after the power is equally divided, so that the air duct utilization ratiois improved, the service life of the fan is prolonged, and the running power consumption of the system is reduced.
Description
technical field [0001] The invention relates to the field of electric vehicle charging, in particular to a heat dissipation control method for a charger cabinet, a charger, a monitoring unit thereof, and a memory. Background technique [0002] As the battery capacity of electric vehicles increases and the charging rate increases, high-power DC chargers will become the core appeal of the market. How to increase power density and improve system heat dissipation efficiency has become a new research topic in the industry. In terms of maintainability, reliability, and cost, forced air cooling is still the mainstream cooling solution used in the industry. The air duct, external fan, and layout of the forced air cooling system have also become key research directions; in terms of capacity expansion, maintenance, cost, and compatibility, the DC charging industry adopts a system integration solution with built-in AC / DC power modules, so Module logic control has also become the key t...
