FIELD: heating. ^ SUBSTANCE: invention relates to heat engineering, namely, to plate-type heat-exchangers. The heat-exchanger consists of a core enclosed in a shell with upper and lower walls and a pair of opposite side walls. The heat-exchanger housing contains upper plate being adjacent to the upper wall and lower plate being adjacent to the lower wall and a pair of side plates adjoining each of side walls. In addition, the upper plate is attached to the lower plate and side plates are interconnected. So the housing plates are interconnected by means of threaded fastenings and include spaced pins. Besides, the side plate pins are placed between the upper and lower plates pins. ^ EFFECT: reduction of heat-exchanger production and assembling costs due to support housing strengthening and using less strong and less expensive shell. ^ 19 cl, 6 dwg |
