FIELD: heating.SUBSTANCE: in plate-type heat-exchanger with natural supply of cooling air containing casing, with tube sheets and cover plates with a pack of heat-exchange plates between them forming channels for cooled and cooling media, there made are inlet and outlet fittings in cover plates for input and output of heat-exchanging media. At that the casing is made U-shaped, horizontal, with a bottom and two butt ends being the lower tube sheet and two end tube sheets. End and upper edges of U-shaped horizontal casing, edges of end cover plates and upper cover plate are provided with flange strips, upper cover plate is designed with upper tube sheet, channels of heat-exchanging media are connected to corresponding holes in upper and lower tube sheets and end tube sheets and are directed vertically and horizontally, and outlet fitting of cooling medium (air) is connected to vertical exhaust pipe with deflector.EFFECT: improving efficiency and reliability of heat-exchanger with natural supply of cooling air.6 dwg |
