摘要:
Reinforcement holes (11b) and tube holes (11a) are formed in header members (11) so as to be of the same size, and the interval (L') between the reinforcement hole (11b) and the tube hole (11a) adjacent to the reinforcement hole (11b) is made equal to the interval (L) between the adjacent tube holes (11a).
摘要:
A tank of heat exchanger (100) comprises a tank body (102) and a pipe member (106). The tank body (108) is made of clad metal and shaped like a channel member with a base wall (102c) and two opposed side walls (102a,b). The pipe member (106) is first spot welded with its flance (110) to the tank body (102) and then finally brazed in a furnace.
