Production method of roll-bond evaporator for new energy equipment

Abstract

The invention relates to the field of heat exchangers, in particular to a production method of a roll-bond evaporator for new energy equipment. The invention discloses a production method of a roll-bond evaporator for new energy equipment. The production method comprises the following steps: a, annealing an aluminum plate; b, the aluminum plate is subjected to roller brushing and roughening to form a rough aluminum plate; c, ink printing is conducted on the rough aluminum plate; d, drying the printed rough aluminum plate in a drying oven; e, covering an aluminum plate on the rough surface of the rough aluminum plate to form a double-layer aluminum plate; f, heating the double-layer aluminum plate; g, carrying out hot rolling on the double-layer aluminum plate; h, performing cold annealing on the hot-rolled double-layer aluminum plate; i, leveling and punching the double-layer aluminum plate; j, the holes formed in the double-layer aluminum plate are subjected to air blowing expansion forming, and annealing and roughening are conducted on the aluminum plate in the step a and roughening are conducted on the aluminum plate in the step b at the same time through an annealing and roughening all-in-one machine; the rough surface of the rough aluminum plate in the step e is covered with an aluminum plate, the aluminum plate is also a rough aluminum plate, and the rough surfaces of the two rough aluminum plates are covered face to face to form a double-layer aluminum plate. The method has the beneficial effects that the two roughened aluminum plates are tightly combined after being hot-rolled, so that the quality of the evaporator is improved, and the service life of the evaporator is prolonged.

Description

technical field [0001] The invention relates to the field of heat exchangers, in particular to a production method for an inflation evaporator used in new energy equipment. Background technique [0002] Most new energy equipment uses electricity as the main source of energy supply. Energy conservation and emission reduction has become the main theme and keynote of enterprises and markets. Most new energy equipment develops in the direction of small size and less space. It needs to be dissipated, otherwise it is easy to cause danger, so these devices will use flat-plate evaporators when dissipating heat. Ordinary flat plate evaporators have a short service life, and the flat plate evaporator composed of two plates has limitations in technology and production methods, which is likely to cause leakage and shorten the service life. [0003] For example, the production method of the inflation evaporator whose patent number is ZL201210210389.3 provides a production process of the...

Ordinary flat-plate evaporators have a short service life, and the flat-plate evaporator synthesized by two plates has limitations in technology and production methods, which may easily cause leakage and shorten service life

[0003] For example, the production method of the inflation evaporator whose patent number is ZL201210210389.3 provides a production process of the flat evaporator, mainly through the cutting, annealing, roughening, drying, cladding, annealing and inflation of the aluminum plate. , straightening and other steps to obtain the blown evaporator, because this method is the aluminum plate annealed and then cooled and roughened, the consistency and plasticity of the rough surface of the aluminum plate cannot be guaranteed, so the evaporator can be used in ordinary household appliances and commercial appliances. , if the evaporator is used in a complex and changeable environment, and sometimes in harsh working conditions, it will cause early leakage of the evaporator and a short service life. The above-mentioned production process is to directly coat a roughened aluminum plate with an ordinary Aluminum plates, ordinary aluminum plates and roughened aluminum plates are no problem in normal temperature environment, but there will be great hidden dangers when new energy equipment or new energy vehicle batteries are used for heat dissipation. The environment in which energy equipment is installed depends on its use New energy vehicles will run under any temperature and working conditions throughout the year. When using an ordinary flat-plate evaporator, the loss of function of the evaporator will easily cause safety hazards and even lead to major accidents.
