Title:
HEAT PIPE HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/1983/000380
Kind Code:
A1
Abstract:
A heat pipe heat exchanger in which groups of heat pipes are arranged within a box, the center of which is partitioned, a high temperature fluid flows on one side, a low temperature fluid flows on the other side, thereby transferring the heat of the high temperature fluid to the low temperature fluid via fluid sealed in heat pipes. In the heat exchanger, a plurality of heat pipes which are bare tubes at least on the high temperature fluid passage side are arranged across both passages, and the heat pipes on the high temperature fluid side are inserted into pipes without fins. At least the outer surfaces of the pipes without fins are treated for corrosion resistance. Since the pipes without fins and the heat pipes are joined by a thermally conductive substance, the heat pipes can be easily removed, and accordingly the efficiency of the heat exchanger can be increased or decreased as required.
