Background technique
Evaporator is a component and a kind of dividing wall type heat-exchange apparatus critically important in four big parts of refrigeration.Low temperature
" liquid " body is condensed by evaporator, carries out heat exchange with extraneous air, " gas " changes heat absorption, achievees the effect that refrigeration.Evaporator
Divide three kinds of normal pressure, pressurization and decompression by operating pressure.Evaporator fin be gas with it is most widely used in liquid heat exchanger
A kind of heat exchange equipment.
Early stage evaporator surface frosting, due to discharging latent heat when frost layer formation, and the coarse of heating surface is increased
Degree and heat transfer area, the heat-transfer capability of evaporator is reinforced (when the equivalent diameter of pipeline is less than critical thermal insulation radius,
The accumulation of frost layer promotes the heat exchange between refrigerant and air, when it is greater than critical thermal insulation radius frost layer hinder refrigerant with
Heat exchange between air).
With the thickening of frost layer, effective ventilation area between fin is reduced, and increases the flow resistance of air, is reduced
The flow of air.The heat transfer resistance in evaporator between working medium and air is increased, thus makes the heat transfer deterioration of evaporator, working medium
Under the heat absorption capacity of air, drop refrigerating capacity reduces, and cold cooling is difficult, and refrigeration compressor power consumption increases, refrigerating efficiency decline.
Since the heat-transfer capability of air working medium into evaporator weakens, being possible to the liquid refrigerant in evaporator can not be complete
Portion's endothermic gasification, causes worker quality liquid to enter compressor, causes liquid hammer, damages compressor.
The fin of evaporator fin used in industry is rectangle at present, the too small easy row of spacing between fin and fin
Cheng Shuiqiao, frosting, icing, the excessive low efficiency of spacing, have short grained droplet to be still attached on fin after fin surface defrost,
Fin bottom portion has more droplets for a plane defrost hind wing piece bottom and hangs on fin, and ice particle can be gone into after refrigeration, then
It is easy to appear that defrost is not clean and ice particle falls generation noise when secondary defrost.
