Description

technical field [0001] The invention relates to the technical field of cooling equipment for charging facilities, in particular to a high-power liquid-cooled super fast charging equipment. Background technique [0002] The charging facility is a device used for energy replenishment of electric vehicles, and its charging performance is related to the service life and charging time of the battery pack. In order to achieve fast, efficient, safe and reasonable supply of power to the power battery, it is often hoped to increase the output power of the charging facility; the working environment temperature of the general charging facility is -20℃~+50℃, and the charging current does not exceed 250A. Under this condition It can ensure the efficiency and safety of charging facilities. The charging efficiency of charging facilities is generally in the range of 90-95%, that is, there is about 8% of the electrical energy loss when the charging facility is in use, and the lost electrical...

Problems solved by technology

[0004] 1. The need for heat dissipation is relatively large. For example, if the charging efficiency of a 600KW charging facility is 90%, the heat generated when it is used at full load is 60KW. 2 For the equipment, the heat density is very high; especially in summer, the higher temperature and sunlight will aggravate the temperature rise of the equipment, and the required heat dissipation will further increase. The traditional air cooling mode cannot meet the heat dissipation needs;

[0005] 2. When the refrigerant refrigeration cycle is used for heat dissipation, due to the low evaporation temperature of the refrigerant, it is easy to produce condensed water, and the condensed water is more during the rainy season with high humidity, which is likely to cause electrical safety accidents
