Abstract
A laminated heat exchanger includes a plurality of parallel spaced tube elements with tanks at one end thereof, and fins disposed between adjacent tube elements. Each tube element has a pair of joint portions projecting from the other end thereof toward two adjacent tube elements and held in abutment with the joint portions of the two adjacent tube elements. The joint portion has a corrugated shape composed of alternate parallel grooves and ridges and hence is rigid enough to withstand external forces. The tube element includes a guide member disposed on a front end of the partition wall for directing a heat transferring medium toward the opposite corners of a guide channel. With the guide member, the heat transferring medium is distributed uniformly over the entire region of the guide channel.
