Background technology
At present, in summer, when automobile in motion, engine coolant temperature generally remains on the temperature of 70 DEG C-90 DEG C.Due to the heating system that the cooling water flow of driving engine forms through H Exch, do not needing in the season of heating the heat effects occupant's of H Exch conduction comfort level.In the time opening air conditioner refrigerating, owing to better not closing the heating system being formed through H Exch by engine cooling water, although closed warm air system air door, the heat being conducted by H Exch, can make can produce sultry dry sensation in car, also affect refrigeration and the comfort level in car, consumed a large amount of heats, affected the temperature in car.Because, the H Exch and the engine water tank that are installed in Auto Instrument desk are communicated with, radical function is heating, and the evaporator of H Exch and air-conditioning refrigeration system is all arranged in the same assembly of instrument, with air door close adjustment of cold/warm system, although closed air door, the natural heat dissipation of H Exch also affects refrigeration degree and the comfort level in car, so, can produce sultry dry sensation.The patent No. is that the utility model patent " the auxiliary cooling device of air conditioning for automobiles " of CN201220702442.7 flow to heat-exchanger pipeline although adopt solenoid valve shuts by engine cooling water, but this technical scheme will be cut off cooling water flow to H Exch as long as AC switch one is opened, in fact, in the time that coolant water temperature is below 60 DEG C, its inflow heat exchanger is little to the comfort degree in car, start this pipeline of solenoid valve shuts, can increase the energy consumption of storage battery; In the time that external temperature is lower, even if chaufeur has been opened AC switch, do not need to cut off this pipeline yet, particularly low in external temperature, need to open warm air conditioner time, because there is no outdoor temperature switch, as long as drive AC switch, electromagnetic valve just cuts off the passage of cooling water expansion tank to H Exch, and air conditioning warm air system cannot be used.
Summary of the invention
The purpose of this utility model is to provide when a kind of automobile is opened air conditioner refrigerating utilizes solenoid valve shuts to be flow to the auxiliary cooling operatorless device of the air conditioning for automobiles of heat-exchanger pipeline by engine cooling water.
The utility model proposes a kind of auxiliary cooling operatorless device of air conditioning for automobiles, Access Control branch road in parallel and electromagnetic valve branch road on the storage battery of automobile, control loop, cooling-water temperature switch, outdoor temperature switch, the low-voltage protective switch of on described control branch road, connecting ignition lock, AC switch, relay; Output loop, the electromagnetic valve of the upper relay of connecting of described electromagnetic valve branch road; Described low-voltage protective switch is connected with the pressure sensor being located in air-conditioning low-voltage tube; described cooling-water temperature switch is connected with the cooling-water temperature sensor being located in automobile cooling water pipe; described outdoor temperature switch is connected with the outdoor temperature sensor being located in outdoor environment, and described electromagnetic valve is located at automobile engine cooling water and leads on the pipeline of H Exch.
Preferably, when reaching 0.3mpa in air-conditioning low-voltage tube and during with upward pressure, described pressure sensor sends signal, the low-voltage protective switch closure of open type; In the time that outdoor temperature reaches design temperature, described outdoor temperature sensor sends signal, the outdoor temperature switch closure of open type; When cooling water expansion tank water temperature reaches set water temperature when above, described cooling-water temperature sensor sends signal, the cooling-water temperature switch closure of open type.
The design temperature of described outdoor temperature is 20 DEG C, and the set water temperature of described cooling water expansion tank is 60 DEG C.
Described air-conditioning low-voltage tube refers to the air-conditioner pipe that connects compressor and evaporator, the safety box of also connecting on described electromagnetic valve branch road.
Described relay is arranged in Auto Instrument desk or driving engine side.
The beneficial effects of the utility model are: automobile utilizes solenoid valve shuts to flow to heat-exchanger pipeline by engine cooling water while opening air conditioner refrigerating, thereby reach fast-refrigerating, make to lower the temperature rapidly in car more comfortable, this air-conditioning refrigeration device for automobile is simple in structure, cooling/warming system is easy to adjust, there is the low effect of cost high, fuel-efficient, extend the service life of driving engine and a/c system.When in the time that coolant water temperature is below 60 DEG C, it is little to the comfort degree in car that cooling water expansion tank flows into H Exch, starts this pipeline of solenoid valve shuts, avoids the energy consumption of storage battery; When air-conditioner pipe inner refrigerant very few; its pressure is during lower than 0.3MPa; the compressor meeting running no load of air-conditioning; produce heating and damage compressor; this device is only the in the situation that of the normal work of a/c system; could use, low-voltage protective switch just plays this control action, avoids the energy consumption of storage battery simultaneously.When external temperature is lower than design temperature, during as 20 DEG C, even if open AC switch, outdoor temperature switch is also disconnected, and has avoided in the situation that temperature is low shut electromagnetic valve, cannot enable heating system, therefore outdoor temperature switch can be convenient to the exchange adjusting that a/c system is realized refrigeration, heated.In electromagnetic valve branch road, establish safety box, for circuit appliance safety, in case electromagnetic valve coil short circuit.
