Abstract
The invention discloses an automobile air conditioning evaporator refrigeration method. The method includes the following steps that (a), refrigerants flowing out from a throttling gear of an automobile air conditioning system enter into an upper air chamber of a rear heat transfer module through a liquid inlet flow channel, and flow into each multi-hole flat pipe of the rear heat transfer module; and (b), subsequently, the refrigerants enter into a lower air chamber of the rear heat transfer module and enter into a lower air chamber of a front heat transfer module through overflow holes, then the refrigerants flow along multi-hole flat pipes of the front heat transfer module, with the heat transfer process between the refrigerants inside the pipes and cooled air outside the pipes, the refrigerants are gradually converted into superheated gas from a gas-liquid two-phase state, and finally the superheated gas flows out from air outlet pipes of an upper air chamber of the front heat transfer module. The method has the beneficial effects that (1), the refrigeration effect is great; (2), a main body mechanism of an evaporating chamber is made of aluminum materials, so that the whole weight of the evaporating chamber is light; and the design of a distance piece has the effects of diffluence and confluence so that the inner effective volume can be reasonably utilized, and the heat transfer efficiency is improved.
