A kind of automobile air-conditioning evaporator
Technical field
The present invention relates to auto parts fields, and in particular, to a kind of automobile air-conditioning evaporator.
Background technology
Automobile air-conditioning evaporator is one kind of evaporator.The effect of A/C evaporator is using liquid low temperature refrigerant low
Pressure easily evaporation, is changed into steam and absorbs the heat of cooled medium, reach refrigeration purpose.When air conditioning for automobiles works, evaporation
The temperature on device surface is relatively low, and the water vapour in air will condense into water when passing through evaporator on its surface, due to evaporator
It is disposed vertically in the housing, condensed water is acted on by gravity and air-conditioning fan power, is flowed downward along fin surface, and steaming is gathered in
Send out device bottom, if the condensed water after afflux cannot be discharged in time, not only can because condensed water spread caused by air-conditioning exchange capability of heat
Decline, but also there is the risk for influencing refrigeration system normal operation because of evaporimeter frosting.Therefore, consolidating in base of evaporator
Determine to must be provided with condensed water guider on frame, to ensure the smooth discharge of condensed water, on evaporator fin increasing prevents from steaming
It is also necessary to send out the heat generating device of device frosting;Condensed water in traditional evaporator on condenser pipe cannot be effectively along condenser pipe
Surface is smooth to be left, and the parts of evaporator can be caused to freeze and risen brokenly, can be adversely affected in this way to the use of evaporator,
Evaporator traditional simultaneously is unreasonable due to its structure, causes its heat absorption capacity weaker, refrigeration effect is bad.
