HEAT EXCHANGER FOR VERTICAL DRAINPIPE AND WASHBASIN EMPLOYING SAME

WIPO Patent Application WO/2020/017803

A1

Disclosed are a heat exchanger for a vertical drainpipe and a washbasin employing same. The heat exchanger for a vertical drainpipe according to the invention comprises: an upper cover having a tube shape and having a diffusion portion provided on the bottom surface thereof so as to slope outwards; a front cover and a rear cover having semi-cylindrical shapes, the front cover and the rear cover being coupled to the upper cover and coupled to each other so as to form a cylinder-type exterior having a cavity at the center thereof, coupling racks being formed on outer ends of the front cover and the rear cover, respectively; a lower cover having a tube shape, the lower cover being coupled to the lower portion of the cylinder formed by coupling of the front cover and the rear cover; and a coil tube contained in a housing formed by coupling of the upper cover, the front cover, the rear cover, and the lower cover. Both ends of the coil tube contained in the housing are fitted to cylindrical through-holes formed through outer peripheral surfaces of the upper and lower portions of the front cover or the rear cover in the horizontal direction such that the two ends protrude outwards. A high-temperature fluid widely flows down along the diffusion portion of the upper cover, and flows down along the surface of the coil tube, thereby exchanging heat therewith.
