The automobile engine cooling system is simple in structure and convenient to use; an engine can be rapidly cooled and refrigerated through the large circulating cooling unit and the small circulating cooling unit respectively according to actual temperature conditions in the engine so that the engine can reach the normal working temperature as soon as possible, the service life of the engine is prolonged, and power consumption is greatly lowered.
Description
Technical field
The present invention relates to a kind of car engine cooling system.
Background technique
At present, the function of cooling system is that motor is all remained in suitable temperature range (as 85 ~ 100 DEG C) under all operating modes, should prevent engine overheat, motor also will be prevented excessively cold; After the start of engine, cooling system also should be able to make motor rapid temperature increases, reaches normal operating temperature as early as possible.Traditional car engine cooling system is made up of the water jacket etc. in water pump, radiator, cooling fan, thermostat, compensation tank, engine body and cylinder head, and the pressure that water pump improves cooling liquid makes it to circulate in systems in which.Engine coolant circulation route is divided into major cycle and short circle, regulated by thermostat, when the engine has the low temperature, cooling liquid only carries out short circle at engine interior, directly get back to unit fixed on water pump suction without radiator, be raised to its operating temperature faster to make the temperature of motor; After engine operating temperature reaches normal temperature, cooling liquid starts to carry out major cycle, and cooling liquid is through radiator, and meanwhile, radiator fan work, strengthens the heat radiation to radiator, and motor is remained in normal operating temperature range.Thermostat is the valve of the coolant flow paths (i.e. circulation route) controlled by paraffin, due to the impact of high temperature and working environment, losing efficacy easily appears in thermostat, degradation fault under control accuracy, cause engine operating temperature abnormal, thus affect the power character of motor, Economy and emission performance.

Embodiment
Shown in Fig. 1, relate to a kind of car engine cooling system, comprise do-part and control section; Described do-part comprises the engine body 1 being provided with cylinder body intake pipe 2 and cylinder body outlet pipe 3; The major cycle cooling unit matched with described engine body 1 and short circle cooling unit is respectively arranged with in the side of described engine body 1.
Wherein, described major cycle cooling unit comprises major cycle pipe 5, and its one end is connected with described cylinder body outlet pipe 3, and the other end controls electromagnetic water valve 6 through major cycle and is connected with multi-pipe radiator 11, and is connected in described engine body 1 by described multi-pipe radiator 11.
Described short circle cooling unit comprises short circle pipe 8, and its one end is connected with described cylinder body outlet pipe 3, and the other end controls electromagnetic water valve 7 through short circle and is connected with single tube radiator 10; And be connected in described engine body 1 by described single tube radiator 10.
Shown in Fig. 2, control section of the present invention comprises storage battery 21, and the first output terminal of this storage battery 21 is connected with the collector electrode of triode 24 by the normally opened contact switch of relay 23, and the emitter of described triode 24 is connected with electric fan 25;
Second output terminal of this storage battery 21 is connected with coil one end of control unit of engine 26 and relay 23 respectively by ignition switch 22;
The signal input part of described control unit of engine 26 is connected with cooling-water temperature sensor 27; First signal output part of described control unit of engine 26 is connected with the coil the other end of relay 23, its secondary signal output terminal is connected with the base stage of triode 24, its the 3rd signal output part controls electromagnetic water valve 6 with major cycle and is connected, and its 4th signal output part controls electromagnetic water valve 7 with short circle and is connected.
Its basic functional principle is as follows: when ignition switch 22 is opened, and control unit of engine 26 obtains electric, and the coil of control relay 23 obtains electric, and make the normally opened contact switch adhesive of relay 23, now system enters working state.
Now, control unit of engine 26 constantly can receive the engine water temperature signal that cooling-water temperature sensor 27 gathers, when engine water temperature is lower than a certain value (as 85 DEG C), control unit of engine 26 control major cycle control electromagnetic water valve 6 close, short circle control electromagnetic water valve 7 open, cooling system carries out short circle cooling; When engine water temperature is higher than a certain value (as 85 DEG C), control unit of engine 26 control major cycle control electromagnetic water valve 6 open, short circle control electromagnetic water valve 7 close, cooling system carries out major cycle cooling; Meanwhile, control unit of engine 26 controls wind triode 24 with certain duty cycle signals and works, and makes electric fan 25 with certain rotational speed, dispels the heat to multi-pipe radiator 11.Now, engine water temperature is higher, and duty cycle signals is larger, and electric fan rotating speed is faster, and radiating effect is stronger.
