摘要

PURPOSE:To bring a gas to be condensed into direct contact with a cooled liquid for condensation and thereby to improve a heat transfer performance of a condenser by a construction wherein the liquid to be cooled down by a heat exchanger tube is filled up in a condensation chamber and a bubble producing means for introducing the gas to be condensed in a state of bubbles into said filled-up liquid is provided in the bottom part of the condensation chamber. CONSTITUTION:When cooling water 17 is made to flow into a lower chamber 5b of a cooling water supply chamber 5 from a cooling water inflow port 13, the cooling water 17 flows through a heat exchanger tube 6, passes through an upper chamber 5a of the cooling water supply chamber 5 and is discharged from a cooling water outflow port 12. With the heat exchanger tube 6 cooled thereby, a chlorofluorocarbon liquid 10 filled up in a condensation chamber 4 is cooled down by the heat exchanger tube 6. The heat transfer between the heat exchanger tube 6 and the liquid chlorofluorocarbon 10 is the one between a solid and a liquid on the occasion, and therefore a heat transfer performance is improved in comparison with heat transfer between a solid and a gas. Chlorofluorocarbon gas is introduced in a state of bubbles into said cooled chlorofluorocarbon liquid 10 through a bubble producing plate 15. Then these bubbles are cooled to be condensed by the chlorofluorocarbon liquid 10 in a process of their rising up to the upper part of the condensation chamber 4.
