A condenser is disclosed which is provided with a forced cooling system adapted to effect forced cooling of a gaseous coolant in the condenser by exchange of heat with water. This forced cooling system comprises an evaporation chamber disposed in a coolant inlet side flow path of the condenser and provided therein with fins, a vacuum tank (or a water pump) for circulating water in a closed flow path passed through the evaporation chamber, an orifice for decompressing the water being introducing into the evaporation chamber, and a control device for effecting circulation of water only when necessity arises. The water is aspirated, when necessary, by negative pressure from a water storage tank, decompressed to a prescribed saturated pressure by the use of the orifice and consequently atomized and allowed to flow into the evaporation chamber, and allowed to deprive the gaseous coolant at high temperature of a large amount of the latent heat of vaporization and consequently cool the gaseous coolant. As a result, the operating ability of condenser is notably improved.
