摘要： A heat exchange apparatus comprises an evaporation unit 1 for exchanging heat between a working fluid and a high-temperature fluid to thereby evaporate the working fluid, a condenser unit for exchanging heat between the working fluid and a low-temperature fluid to thereby condense the working fluid, an evaporation-side communication unit 5a for leading the working fluid evaporated in the evaporation unit 1 to the condenser unit 2, and a condenser-side communication unit 5b for leading the working fluid condensed in the condenser unit 2 to the evaporation unit 1. The high-temperature fluid is prevented by condenser-side shield plates 101, 102 from flowing to the condenser-side communication unit 5b. As a result, the heating and evaporation of the working fluid in the condenser-side communication unit 5b by the high-temperature fluid is prevented or reduced thereby preventing a dry-out phenomenon.
