PURPOSE:To prevent drain water from scattering and contrive to make the water to be dropped steadily in a water reservior by a method wherein the width dimension of a partition plate provided at the lower part of a heat exchanger is shortened in air flowing direction. CONSTITUTION:The width of a heat exchanger lower plate 10 is formed smaller than that of a fin 12. The lower end part downstream side of the heat exchanger is protruded in the water reservior from the top end of an air passage partition plate. Therefore, a drain water produced in the heat exchanger is dropped on the heat exchanger lower plate 10 or a water reservior 8, but does not scatter in horizontal direction. An air flowing is made to be flowed along the heat exchanger lower plate 10, and made to be expanded downward at the end part of the heat exchanger lower plate 10, then the air flowing speed is made slow and the air is flowed downward. Thereby, the drain water is prevented from scattering, the drain water can be made to be dropped steadily in the water reservoir. |
