1. A latent heat exchanger comprising:
- a casing having a flow path of combustion gas therein;
a heat absorbing pipe accommodated in the casing;
an inlet header for introducing fluid to be heated into the heat absorbing pipe; and
an outlet header for discharging the fluid to be heated from the heat absorbing pipe, whereinthe casing has a box-shaped casing body having an upper opening and a top board closing the upper opening of the casing body,the casing body has a back wall, a front wall, a bottom wall having a drain discharging opening, one side wall having an upstream end-inserting hole through which an upstream end of the heat absorbing pipe is inserted and a downstream end-inserting hole through which a downstream end of the heat absorbing pipe is inserted, and the other side wall,the back wall, the front wall, the bottom wall, the one side wall, and the other side wall are integrally formed by drawing one single metal plate, andthe inlet header and the outlet header are respectively disposed outside the one side wall and connected to the upstream and downstream ends of the heat absorbing pipe led outside the one side wall through the upstream end-inserting hole and the downstream end-inserting hole.

Abstract
A latent heat exchanger (1) has a casing (2), a heat-absorbing tube (50) accommodated in the casing (2), an inlet header (60), and an outlet header (70). The casing (2) has a casing main body (10) and a top plate (40) closing an upper opening (16) of the casing main body (10). The back wall (11), the front wall (12), the bottom wall (13), one side wall (14), and the other side wall (15) of the casing main body (10) are formed integrally by draw-processing a single metal plate.
