Abstract
Exemplary embodiments of a cooling apparatus cool a charger for charging a storage battery upon reception of a supply of power from a power supply. Exemplary embodiments include a compressor that circulates a refrigerant, a cooling unit provided on a path along which the refrigerant flows between the heat exchanger and the expansion valve to cool the charger using the refrigerant, a refrigerant passage through which the refrigerant flows between the compressor and the heat exchanger, a refrigerant passage through which the refrigerant flows between the cooling unit and the expansion valve, and a connecting passage connecting the refrigerant passage and the refrigerant passage. When heating occurs, frost formation can be suppressed without increasing configuration complexity and power consumption.
