Claims

[Scope of utility model registration request]

A heat exchanger in which the middle part of the pipe is fitted and supported in a mounting hole formed in the side wall of the tank, and the semicircular circumferential wall part at the rear of the pipe is adhered to a mounting wall formed on the other side wall of the tank that protrudes toward the inside of the tank. In the water conveyance pipe of the dexterous tank, the wall portion of the semicircular circumferential wall is bent outward at a right angle at the rear end of the semicircular circumferential wall, and the outer bending radius is set to the inner bending radius of the base of the mounting wall. 1. A water guide pipe for a heat exchanger tank, characterized in that it is provided with a bent piece having a size equal to or larger than .
