Abstract
An automatic electric cooling fan system of a lorry belongs to the field of a design of a lorry cooling system. The automatic electric cooling fan system is characterized in that on-off of a relay is controlled by a temperature controller via water temperature of an inlet of a heat radiator, so on-off of a direct current motor and a cooling fan loop can be controlled; and under each work condition of an engine, cooling liquid temperature is controlled in a preset temperature range to guarantee cooling capability of the engine. Compared with a traditional driving method, the automatic electric cooling fan system of the lorry is advantageous in that rotation and stop of the cooling fan is controlled by cooling liquid temperature; and the automatic electric cooling fan has high work efficiency and low power loss.
Description
Technical field
The utility model relates generally to the design field of truck cooling system, specifically a kind of Automatic control Electric Cooling Fan system.
Background technique
Truck cooling fan is to realize motor to carry out suitably cooling device, and it can take away the heat producing during engine operation, guarantees that motor all remains in suitable temperature range under all operating modes.Truck cooling fan driving mode adopts traditional type and clutch-type more at present, and these two kinds of fans pass through belt drives by engine crankshaft.When truck is worked under high temperature, low speed, high load working condition, motor needs many heat radiations, but now engine speed is lower, and fan discharge capacity is little, is prone to superheating phenomenon; On the contrary, when automobile at low temperature, at a high speed, while working under small load condition, motor requires to reduce to heat radiation, sometimes also need insulation, but cooling fan High Rotation Speed still under engine-driving, cause cooling capacity superfluous, not only wasted the power that motor consumes because of drive fan, and too low coolant water temperature will make engine consumption increase.
Summary of the invention
The purpose of this utility model is to address the above problem, and provides a kind of and can guarantee the suitable cooling capacity of motor, the truck Automatic control Electric Cooling Fan system that working efficiency is high simultaneously, power loss is low.Concrete technological scheme of the present utility model is as follows:
A truck Automatic control Electric Cooling Fan system, mainly comprises direct current motor, cooling fan, temperature controller, relay, storage battery and fan housing etc., and described cooling fan is directly driven by direct current motor, controls the rotation of fan and stops; Described temperature controller is positioned at radiator entrance, according to the break-make of engine water temperature automatic control relay; Described relay, between temperature controller and Vehicular accumulator cell, is controlled the break-make in storage battery, direct current motor, cooling fan loop.
When radiator inlet water temperature is too high, temperature controller is connected Control electric current, cooling fan and direct current motor loop works, fan High Rotation Speed, when water temperature is down to certain value, Control electric current disconnects, direct current motor quits work, fan stall.
Compared with the prior art, major advantage of the present utility model is:
1, adopt motor direct-drive, compare with belt transmission or driven by clutches, can control the rotation of cooling fan under different operating modes and stop, having avoided the power loss of engine-driving cooling fan;
2, adopt temperature controller can realize rationally cooling, during low speed high load, the cooling capacity of fan strengthens, during high speed low-load, cooling capacity weakens, and engine temperature is controlled in certain temperature range, can meet well the radiating requirements of truck under each operating mode;
3, simple in structure, mounting point freely, has solved the problem that resistance of air increase that radiator juxtaposition brings causes the energy consumption to increase.
Accompanying drawing explanation
Fig. 1 is main structure and the control system schematic diagram of truck Automatic control Electric Cooling Fan described in the utility model.
Embodiment
Below in conjunction with 1 pair of the utility model of accompanying drawing, be described further.
1-radiator inleting pipe 2-temperature controller 3-cooling fan 4-direct current motor 5-relay
6-power switch 7-storage battery 8-work indicator light 9-radiator outlet pipe
10-fan housing 11-radiator
A kind of truck Automatic control Electric Cooling Fan system described in the utility model, mainly comprises the assemblies such as temperature controller, cooling fan, direct current motor and relay.Temperature controller induction radiator inlet water temperature, when temperature surpasses capping value, relay 5 is controlled electric current and is connected, and now storage battery 7 is connected with the circuit of direct current motor 4, cooling fan High Rotation Speed, coolant water temperature reduces rapidly.When water temperature is reduced to preset lower limit, temperature controller 2 is relay 5 failures of current, and then direct current motor 4 quits work, cooling fan 3 stalls.To sum up, the rotation of fan and the control that stops being only subject to coolant water temperature, guarantee that motor possesses suitable cooling capacity under each operating mode, and cooling water temperature control is in the temperature range of setting the most at last.
Claims (4)
1. a truck Automatic control Electric Cooling Fan system, comprise direct current motor, cooling fan, temperature controller, relay and fan housing etc., it is characterized in that: according to the radiating requirements under each operating mode of motor, by Vehicular accumulator cell, provide energy, utilize temperature controller by the rotation of relay and DC motor control cooling fan and stop, coolant temperature under each operating mode is all controlled in the temperature range of setting, guarantees that motor possesses suitable cooling capacity.
