The method of calculating sheet-channel heat exchangers used in the thermal equipment of catering

The article considers and substantiates the method of calculating metal panels with tubular channels, as new heat exchangers made of thin steel sheets, which used in thermal equipment at catering establishments. Today, the majorities of steam jackets of technological devices in the food industry arerepresentedby open slotted space and work under pressure, which leads to a thickening of the walls of heat exchangers, and therefore increases the specific quantity of metal. Plate-to-channel heat exchangers, unlike ordinary shirts, are made of thin metal sheets. Panel channel heat exchangers are a structure, which composed of two metal sheets, that are interconnected by contact welding. Heating steam channels are formed between the sheets. The design of sheet-channel heat exchangers can significantly reduce the wall thickness, and thus reduce the metal consumption and reduce the thermal inertia of the equipment. This article describes methods that allow calculating the area of steam channels and obtaining the optimal dimensions of inter-channel sections for sheet-channel heat exchangers of thermal devices of catering enterprises. A method for calculating the heat transfer coefficient based on an experimental study is also given. In order to reduce the thickness of the walls of the panels, it is proposed to maximize the area of inter-channel sections without reducing the heat flux, which the panel transmits to the heated medium. This problem is solved with the help of a calculation method based on the use of the coefficient of efficiency of the thermal edge.
