The cooling system comprises two water pumps, two thermostats, two radiators and other accessories, which form two independent cooling loop. The cooling of the engine body and the engine air feeding is achieved by the dual-pump and dual-loop method, and the two loops share a cooling fan and a compensation tank. The utility model has advantages of possessing compact structure and convenient installation; enhancing engine power; improving tail gas emission of the engine; matching with the cooling of the high-power engine of the mining automobile.
Description
Technical field
The utility model relates to mine truck double pump double loop cooling system, belongs to the mine truck field.
Background technique
What the mine truck of selling in the market and using used all is to have the air inlet turbo-charging diesel motor, for making the work of diesel engine normal reliable, must be furnished with cooling system.Present cooling system structure form is following three kinds of forms: first, a water pump and a water radiator are arranged, water pump makes the cooled engine body that gets up of the coolant flow in motor and the water radiator, and air directly enters motor without cooling after turbosupercharging.This form is owing to the temperature height of gas after the supercharging, and density is little, and air inflow is little, causes the low and discharging variation of engine power.The second, a water pump, a water radiator and an absolutely empty intercooler are arranged, water pump makes the cooled engine body that gets up of the coolant flow in motor and the water radiator, and air is through entering motor after again by absolutely empty intercooler cooling after the turbosupercharging.This form structure is simple, but need do to such an extent that just can meet the demands very greatly when the aerial cooler of the very big space-time of engine power, and this will make cost up, and on vehicle difficulty in installation and layout.The 3rd, a water pump, a water radiator and the aerial cooler of water are arranged, water pump make in motor, the water radiator and the aerial cooler of water in coolant flow get up cooled engine body and air inlet, air is through entering motor by water after the aerial cooler cooling again after the turbosupercharging.Because the absolutely more empty intercooler efficient of the aerial cooler of water is much higher, also it goes without doing just can satisfy the requirement of dispelling the heat very greatly for the aerial cooler of water for high power engine, so this structure is applicable to high power engine.But this structural type is because cooling liquid will be kept the normal working temperature of motor, so temperature is higher, generally about 90 ℃, just can not obtain desirable intake temperature (50 ℃-60 ℃) by this cooling liquid cooling air inlet again, still can reduce engine power and influence discharging.More than the common feature of cooling system of three kinds of forms be to have only a water pump in the system, a cooling liquid flow cycle.
Summary of the invention
The purpose of this utility model is to provide a kind of mine truck double pump double loop cooling system that can make engine body and engine charge reach desirable separately temperature range.
Technological scheme is: the utility model comprises compensation tank, first loop, described system comprises second loop, described second loop comprises: second water pump, the aerial cooler of water, second thermostat, second radiator, second water pump is connected with the aerial cooler of water, the aerial cooler of water is connected with second thermostat, second thermostat is connected with second radiator, second radiator is connected with second water pump, described second water pump is connected with second thermostat by the short circle pipeline, be provided with gas pipeline between second thermostat and the compensation tank, be provided with gas pipeline and compensation conduit between the compensation tank and second radiator.
First loop comprises first radiator, and first radiator below is provided with fan.
The utility model system adopts two water pumps, and two radiators and the aerial cooler of water form two independently cooling liquid flow cycles.By two independently the cooling liquid flow cycle can control the temperature of engine charge and engine body respectively, improve engine charge efficient, increase engine power and also improved engine emission.This mode compact structure, easy for installation, be applicable to the mine truck that mates high power engine.
