Electric automobile realizes in defrosting, demist and the comfortableness demand process, and how the heat with PTC water heating unit passes to cooling fluid efficiently, is most important link with the loss that reduces electric energy.
Summary of the invention
In order to address the above problem, the invention provides a kind of heat that can make electric automobile air conditioner PTC water heating unit heat sink arrangement with heat convection function that liquid absorbs efficiently that is cooled.
Technical solution of the present invention is: a kind of heat sink arrangement with heat convection function comprises the housing with inlet and liquid outlet and is installed on the interior radiator of housing, described radiator bottom is provided with a plurality of radiator fins that are used for heat convection that are parallel to each other and arrange, be equipped with the cooling fluid circulation passage between the adjacent radiator fin and between the radiator fin of close housing and the inner walls, radiator fin inside is provided with for the mounting groove of arranging the PTC heating element heater, and radiator fin side is for being undulatory heat-transfer surface.
Further, the ripple of described corrugated heat-transfer surface and the joint face between the ripple are arc surface.
Further, the crest of a described radiator fin heat-transfer surface is corresponding with the crest of adjacent another radiator fin heat-transfer surface.
Further, the crest of a described radiator fin heat-transfer surface is corresponding with the trough of adjacent another radiator fin heat-transfer surface.
Further, the bottom of described radiator fin is provided with laterally some or increases longitudinally the groove of cooling fluid disturbance.
Further, the described inner walls position relative with the radiator fin is corrugated, and the crest of the heat-transfer surface of the radiator fin of close housing is corresponding with the trough of the corrugated inwall of housing.
The invention provides a kind of air-conditioning PTC aluminium alloy heat radiator device for electric automobile, itself and heat-generating units and shell combination form a high efficient heat exchanging system.This heat sink arrangement has corrugated and strengthens the heat convection face, and is simple in structure, increased the production rate of turbulent flow between the radiated rib runner, reduced the thermal resistance between heater element and the cooling medium, improved the reinforcement heat convection efficient of aluminium alloy heat radiator.This heat convection feature can effectively solve the problem of the defrosting of pure electric automobile front windshield, demist and occupant's heating.
