Abstract
A heat exchanger apparatus has a hot-fluid casing and a cold-fluid casing which are separated from each other by a partition plate and through which a fluid of a higher temperature and a fluid of a lower temperature pass, respectively. The hot-fluid casing accommodates a plurality of heat transfer tubes charged with a heat medium and connected at their ends to respective headers so as to constitute an evaporator panel. The cold-fluid casing also accommodates a plurality of heat transfer tubes similar to that in the hot-fluid casing and connected at their ends to respective headers so as to constitute a condenser panel. The header on the medium outlet side of the evaporator panel and the header on the medium inlet side of the condenser panel are positioned substantially at the same level. The header on the medium outlet side of the condenser panel is disposed above the header on the medium inlet side of the evaporator panel and these headers are connected to each other through a connection pipe.
