CONDENSER AND COOLING DEVICE

In the condenser provided with two of the degassing chambers separated by a cooling fluid, communication between the degassing chambers is prevented even if a pressure difference is increased between the degassing chambers. The condenser has the housing having the vapor inflow port connectable to the discharge portion of the compressor, the first degassing chamber, in the housing, communicating with the vapor inflow port, and the second degassing chamber, in the housing, arranged above the first degassing chamber across the partition portion, and the passing portion for permitting a cooling fluid to flow from the second degassing chamber to the first degassing chamber, wherein the first degassing chamber is separated from the second degassing chamber by the cooling fluid in the passing portion , and the passing portion has a pressure head space for containing a specified volume of cooling fluid so as to absorb a variation in a pressure difference between the first degassing chamber and the second degassing chamber.
