COOLING DEVICE

摘要

A space in a machine compartment is effectively used to secure a sufficient head between a heat exchanger and an evaporator.  A cooling device is provided with a secondary circuit (44) having a secondary heat-exchanging section (46), which condenses a gas phase secondary refrigerant into a liquid phase secondary refrigerant, and also having an evaporator (EP), which evaporates the liquid phase secondary refrigerant into the gas phase secondary refrigerant.  The secondary heat-exchanging section (46) and the evaporator (EP) are connected to each other by liquid piping (48) and gas piping (50).  The liquid phase refrigerant is caused to flow from the secondary heat-exchanging section (46) to the evaporator (EP) through the liquid piping (48), and the gas phase refrigerant is caused to flow from the evaporator (EP) to the secondary heat-exchanging section (46) through the gas piping (50).  A heat exchanger (HE) is located above a compressor (CM) mounted in a machine compartment and is located below a condenser (CD) mounted in the machine compartment (20) and forming a primary circuit (34).
