Abstract
Counterflow heat exchanger with a floating plate, which comprises a casing made of a pair of rectangular parallel-spaced wall members and four pieces of bar members connecting the corresponding corners of the pair of wall members, a pair of seal strips located inside said bar members through elastic members diagonally with regard to a line connecting the centers of the wall members, being extended so as to cover and seal a pair of the sides formed by a longer side of the wall members and the bar members, leaving a part of the sides uncovered. More than two sheets of floating plates are spaced apart from each other contained in a space formed by the seal strips and wall members. A spacer in a channel is formed between the floating plates, and a structure for controlling the flow of fluids within the channels is included. By making fluids having different temperatures flow countercurrently to each other through the channels, efficiency of heat exchange of the heat exchanger can be improved. The construction affords easy assembly and also a compact form.
