Abstract (en)
[origin: EP0805331A2] A multi-tube heat exchanger (100) includes a pair of tanks (1, 2) and a plurality of heat transfer tubes (3) fluidly interconnected between the tanks (1, 2), wherein each heat transfer tube (3) has a radially expanded portion (6) at least at one end portion engaging a tank wall (4 or 5) of a tank (1 or 2). Since a diameter contracted portion is not formed at a tube end portion, increase of pressure loss at a connecting portion of the tube end portion and a tank wall (4 or 5) can be prevented, thereby suppressing the pressure loss small as the whole of the heat exchanger (100) and ensuring a high performance of the heat exchanger (100). <IMAGE>
