Claims

[Scope of utility model registration request]

A compressor, a condenser, an evaporator, an accumulator, etc. are connected in an annular manner, a first pipe is provided between the evaporator and the accumulator, and a second pipe is provided between the accumulator and the compressor. In the cooling device, the second pipe extends upward inside the accumulator from the lower part thereof, has a small hole for returning oil at a suitable position, and has an upper end opening into the accumulator, and has a lower part lower than the accumulator. is formed, the first pipe has a lower part lower than the lower part of the second pipe, and the accumulator is bypassed between the lower part of the second pipe and the lower part of the first pipe. A liquid refrigerant bypass is provided, and the liquid refrigerant bypass pipe is provided with a check valve that allows the refrigerant to flow from the second pipe to the first pipe and blocks the flow in the opposite direction. Features a cooling device.
