Description

FIELD OF THE INVENTION The invention relates to engine-building, in particular to a liquid-type cooling system.

It is known a cooling system device comprising a radiator, a pump, and connecting pipes.

The disadvantage of this device is that it does not provide pre-start heating of the coolant in the system before starting the engine.

Closest to the present invention is a device comprising a fan, blinds, a radiator, a pump.

The disadvantage is the impossibility of heating the fluid in the cooling system before starting the engine.

The purpose of the invention is to increase the efficiency of regulating the thermal state.

The cooling system additionally contains a liquid pump connected to the lower radiator tank, and the cooling jacket is equipped with a gas discharge machine with two electrodes, the first of which is connected to the switch, and the second to the thermal switch, light-absorbing target installed near the discharge plate, injection and suction valves connected respectively to the upper radiator tank and the cooling inlet, the thermostat being designed as a spring-loaded valve disc.

The operation of the cooling system. Before starting the engine, for example, at minus ambient air temperature, the electrodes 1 from the power source 2 with the switch 3 turned on supply a voltage to the gas discharge lamp 4. Between the electrodes 1, a pulse of light is generated, which passes through the housing 5 transparent quartz glass gas discharge lamp 4 and cooling transparent liquid b (for example, distributed or rain water, etc.), is released as heat on the inner wall of the light-absorbing target 9. Part of the coolant 6 instant but effervesce, resulting in the body 8 increases the pressure. The exhaust valve 11 opens and the suction 10 closes, as a result of which the cooling fluid 6 is heated under pressure and enters the inlet of the circulation pump 12 and then into the cooling system jacket 13. Due to overpressure

in the jacket 13, the cooling fluid 6 deforms the spring 21 and opens the disc valve 14. Through the resulting window, the cooling fluid 6 enters the upper connecting pipe 16 and then into the radiator 17. Since the time relay in the control unit 18 provides a pulse voltage supply the electrodes 1, the heating and supply of coolant 6 will occur pulsed The walls of the housing 8 practically do not have time to warm up and most of the heat from the light flux will heat up the light-absorbing target 9 and, therefore, cool waiting fluid 6.

Having warmed up to a temperature of 100 degrees Celsius or more, the cooling fluid 6 passes through the valve 11, enters the circulation pump 12, from which the main mass enters the cooling jacket 13, a small part via the pipeline 27 into the tank 26.

The forced circulation of coolant 6 will continue until the temperature in the engine cooling system reaches 80-85 ° C. At this point, the thermostat valve 19 will open and the disc valve 14 will close synchronously with this, the thermostat of the control unit 18 will turn off the power supply to the electrodes 1. Turning the lever of switch 3 to the Off position and start the engine.

In operation, the circulation pump 12 does not create such a pressure as to overcome the force of the spring 21 at the time of closing the valve 19, and thus open the disc valve 14.

Therefore, the goal is achieved through the use of a spring-loaded disc valve 14, a thermostat 15 which is coaxial with the valve 19, and a gas discharge lamp 4 in the additional liquid pump 29.
