Claims

[Scope of utility model registration request]

In a cooling system that has at least a compressor, a condenser, an expansion valve, and an evaporator, a bypass pipe is provided in the middle of the piping that connects the condenser and the expansion valve, and a heat exchange section is provided in the middle of this bypass pipe, so that the heat The air is arranged so that the air after heat exchange with the exchange section becomes the heat load of the evaporator, and a flow rate control valve is installed at the branch point between the above piping and the bypass pipe so that the evaporation pressure matches a predetermined value. A vehicle cooling device characterized in that the flow rate control valve is controlled as follows.
