PURPOSE:To obtain a heat exchanger having a high heat transfer efficiency by a method in which heat transfer plates are laminated in a zig-zagged form to make up a heat conductor having V-shaped grooves in such a way as to facilitate molding, processing, and assembling and also to reduce the cost of heat exchanger. CONSTITUTION:A heat conductive plate 23 is of a nearly rectangular form, and upper and lower both sides of the plate 23 are provided with differently directed plural paired through holes. The plates 23 are laminated in a ziazagged form in such a way that the edge sides 24a and 25a of the through holes can be joined with the other edge sides of the through holes. Connecting bars 26 are inserted into the holes 24 and 25 for assembling to make up a heat conductor 4 having alternately opened V-shaped grooves 21 and 22. |
