Description
Technical field
Apparatus of the present invention are related to a kind of temperature regulator of air conditioning for automobiles, and more particularly to one kind can intelligently be blocked and started
Machine cooling water to the air conditioning for automobiles of heat exchanger intelligent temperature regulator.
Background technology
At present, in summer, when automobile in motion, engine coolant temperature is generally kept in 70 DEG C -90 DEG C of temperature.
Due to the heating plant that the cooling water of engine flows through heat exchanger and formed, do not needing in the season of heating, heat exchanger
The heat of conduction influences the comfort level of occupant.When opening air conditioner refrigerating, preferably closed due to not cold by engine
But the heating plant that water is formed through heat exchanger, although closing warm air system air door, the heat conducted by heat exchanger,
The in-car sensation that can produce sultry drying can be made, the refrigeration and comfort level of in-car is also have impact on, consume substantial amounts of heat, shadow
The temperature of in-car is rung.Because the heat exchanger being installed in Auto Instrument desk connects with engine water tank, major function
It is heating, and the evaporator of heat exchanger and air-conditioning refrigeration system is all arranged in the same component of instrument, with the closing of air door
Carry out adjustment of cold/warm system, although closing air door, the natural heat dissipation of heat exchanger also influences the refrigeration degree and comfort level of in-car, institute
So that the sensation of sultry drying can be produced.Patent No. ZL 201220702442.7 utility model patent " air conditioning for automobiles it is auxiliary
Help refrigerating plant " although adopt magnetic valve cut-out flow to heat-exchanger pipeline by engine cooling water, as long as the technical scheme
The unlatching of AC switches one shuts off cooling water and flow to heat exchange.Because automobile is frequent starting, also on and off is frequently being beaten
AC switches are closed, when closing AC switches, the cooling water of engine will circulate in heat exchanger, be switched when being again turned on AC
When, although magnetic valve has cut off the pipeline for leading to heat exchanger by engine cooling water, the waste heat in heat exchanger is also kept
With the temperature as engine cooling water, it is necessary to which a period of time could blow waste heat cold, the comfort level of driver's cabin have impact on.
The content of the invention
It is an object of the invention to provide a kind of intelligent temperature regulator for the air conditioning for automobiles for improving control mode, when warm
When fan switch is closed, AC switches no matter are opened or closed, the pipeline of engine cooling water to heat exchanger is all to close；Only
Have when warm-air drier switch connection and AC switch closings, just open engine cooling water to the passage of heat exchanger.
The present invention proposes a kind of intelligent temperature regulator of air conditioning for automobiles, including major loop, closing warm wind gate control branch
Road, warm wind gate control branch road is opened,
Major loop is including being connected to the ignition switch of battery positive voltage in turn by circuit, AC is switched, AIR COND RLY Air Conditioner Relay, empty
The wire loop of relay is adjusted to be connected to after AC switches, the control loop of AIR COND RLY Air Conditioner Relay is connected to before AC switches, air-conditioning
The control loop of relay is provided with a normally-closed contact, a normally opened contact；
Close closing warm wind gate control line, sky that warm wind gate control branch road includes picking out from the normally opened contact of AIR COND RLY Air Conditioner Relay
The shutdown of control line, damper motor is adjusted to rotate forward tie point；
Open unlatching warm wind gate control line that warm wind gate control branch road includes picking out from the normally-closed contact of AIR COND RLY Air Conditioner Relay, open
Open and warm-air drier switch, the wire loop of warm wind relay are sequentially connected in series on warm wind gate control line；The control of warm wind relay is returned
Road positive pole is connected to before the AC switches of major loop, and its negative pole is inverted by enabling of the circuit respectively with magnetic valve, damper motor
Tie point is connected.
Preferably, the negative pole of the wire loop of AIR COND RLY Air Conditioner Relay, the negative pole of wire loop of warm wind relay, magnetic valve
The negative pole of negative pole, the negative pole of damper motor respectively with battery passes through connection.
The AIR COND RLY Air Conditioner Relay is single-pole double-throw relay；The magnetic valve is normally closed solenoid valve.
When the shutdown of the damper motor rotates forward tie point energization, damper motor rotates forward, and drives trace to close warm wind door；
When the enabling reversion tie point of damper motor is powered, damper motor reversion, drives trace to open warm wind door, simultaneously close off evaporation
Device air door.
The beneficial effects of the invention are as follows:Control mode is improved, when warm-air drier switches off, opens or closes AC switches
When, the pipeline of engine cooling water to heat exchanger is all to close；Only closing AD switches, and warm-air drier switch connection
When opening warm air system, engine could be opened to the pipeline of heat exchanger, allow the engine cooling water of higher temperature to enter
Heat exchanger, effectively avoid situations below：Because automobile frequent starting or frequently open and close AC switch when, one parking or
One closes AC switches, and the high-temperature cooling water of engine will circulate in heat exchanger, pass to the heat of heat exchanger, again
, it is necessary to which a period of time could blow the waste heat of heat exchanger cold when opening AC switches, the comfort level of driver's cabin have impact on.Thus
The energy has been saved, has improved the efficiency of refrigeration.Damper motor, which is provided with to close the door, rotates forward tie point, shutdown rotating forward tie point, there is rotating forward
With two kinds of motor patterns of reversion, when it is rotated forward, trace can be driven to close warm wind door, drive trace to open when it is inverted
Warm wind door, evaporator air door is simultaneously closed off, be advantageous to save the energy.The effect of warm wind relay is stable and protection voltage, cold
Warm color tone section is quickly, conveniently.
