Tube plate evaporator bonding technology

Abstract

The invention relates to the field of refrigerating evaporator production, in particular to a tube plate evaporator bonding technology. An evaporator aluminum pipe and an aluminum plate are included. The tube plate evaporator bonding technology comprises the steps that (1), varnish and banana water are compounded and mixed according to the ratio of 1:0.5, (2), the aluminum plate with a sulfuration film is bonded on a snakelike bent pipe through a sulfuration machine; (3), anticorrosion reagents prepared in the step (1) are brushed on the snakelike bent pipe and the aluminum plate which are bonded in the step (2); and (4), a product prepared in the step (3) is dried through a drying furnace. Through the sequence of first, sulfuration bonding and then, anticorrosion paint brushing, it is effectively guaranteed that an anticorrosion layer of the product is protected from being damaged by the subsequent working procedures, and the product prepared by the technology has good anticorrosion performance.

Description

technical field [0001] The invention relates to the production field of refrigeration evaporators, in particular to a tube-sheet evaporator bonding process. Background technique [0002] The refrigerated evaporator is often called a tube-sheet evaporator. It is the main heat exchange device in the refrigeration system. Its function is to quickly evaporate (boil) the low-temperature and low-pressure liquid refrigerant into steam and absorb the heat of the cooled substance. Heat, which lowers the temperature of refrigerated (frozen) substances to achieve the purpose of refrigeration. It is mainly assembled by vulcanization of aluminum tubes and aluminum plates. In the prior art, the aluminum tubes are first subjected to anti-corrosion treatment and then bonded. This production process can easily damage the anti-corrosion layer on the surface of the aluminum tubes. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the p...
