Heat recovery apparatus
First Claim
1. A heat recovery apparatus comprising:
- an evaporating part for performing heat exchange between an internal fluid and a first fluid, thereby to evaporate the internal fluid; and
a condensing part for performing heat exchange between the internal fluid evaporated in the evaporating part and a second fluid having a temperature lower than a temperature of the first fluid, thereby to condense the internal fluid, whereinthe evaporating part and the condensing part are in communication with each other through a looped passage for circulating the internal fluid therethrough, whereinthe evaporating part has a plurality of evaporating heat pipes and evaporating fins, each of the evaporating heat pipes has flange portions projecting from its longitudinal ends in a direction perpendicular to a longitudinal direction of the evaporating heat pipe and each having a tubular shape,the evaporating heat pipes and the evaporating fins are alternately stacked and brazed in a direction perpendicular to the longitudinal direction of the evaporating heat pipes, and the flange portions of the adjacent evaporating heat pipes are coupled to and brazed to each other such that evaporating communication portions are provided by the flange portions and the longitudinal ends of the evaporating heat pipes.

Abstract
A heat recovery apparatus has an evaporating part for evaporating an internal fluid and a condensing part for condensing the internal fluid evaporated in the evaporating part. The evaporating part and the condensing part are in communication with each other through a looped passage for circulating the internal fluid therethrough. The evaporating part has evaporating heat pipes and evaporating fins. Each evaporating heat pipes has flange portions at longitudinal ends thereof. The flange portions project in a direction perpendicular to a longitudinal direction of the evaporating heat pipe and have a tubular shape. The evaporating heat pipes and the evaporating fins are alternately stacked and brazed, and the flange portions of the adjacent evaporating heat pipes are coupled to and brazed to each other such that communication portions are provided by the coupled flange portions and longitudinal ends of the evaporating heat pipes.
