Problems solved by technology

However, for larger power chargers, their volume and heat dissipation are relatively large, and the heat dissipation through air cooling is slow and the heat dissipation rate is low, resulting in a low protection level
The forced air cooling method requires more equipment, resulting in a large area occupied, which makes the installation and layout difficult for the overall layout of the vehicle

Abstract

The invention discloses a vehicle-mounted charger. The vehicle-mounted charger comprises a charger body provided with a first power circuit board and a second power circuit board, and further comprises a liquid inlet and a liquid outlet which are formed on the charger body, and a cooling device provided with an upper cooling board and a lower cooling board, wherein the cooling device is arranged in the charger body; the first power circuit board is mounted on the upper cooling board; the second power circuit board is mounted on the lower cooling board; a cooling channel used for cooling liquid to circulate is arranged between the upper cooling board and the lower cooling board; and the two ends of the cooling channel are respectively communicated with the liquid inlet and the liquid outlet. The specific heat capacity of the cooling liquid is larger than that of air, so that heat of the vehicle-mounted charger can be rapidly dissipated through the circulation of the cooling liquid; and besides, the cooling device is integrated with the vehicle-mounted charger, that is, the cooling device is arranged in the vehicle-mounted charger, so that the space is effectively saved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a vehicle charger. Background technique [0002] An electric vehicle charger is a device specially designed for charging the battery of an electric vehicle. It is a power conversion device with specific functions used when charging the battery. Therefore, as one of the important components of pure electric vehicles, the on-board charger must adapt to the environmental conditions of the vehicle. [0003] At present, the cooling method for electric vehicle chargers is through forced air cooling or natural air cooling. An air inlet and an air outlet are arranged on the trunk, so that the air in the vehicle compartment carries the heat emitted by the heat dissipation part of the electric vehicle charger and is discharged from the air outlet through the air exhaust duct. However, for a higher-power charger, its volume and heat dissipation are relatively large, and the heat...
