Description
Technical field
The utility model relates to various engine charge cooling infrastructures, particularly a kind of engine booster air inlet twin-stage cooling unit.
Background technique
At present, what supercharged engine generally used is high temperature circulation water, enter the heat exchanger circulating cooling behind cooled engine cylinder cap, the body, low temperature refrigeration circulating water enters intercooler cooled gas, oil cooler cooling machine oil successively, use this cooling infrastructure and have following shortcoming or deficiency: 1. common combustion gas supercharged engine is not when having external equipment or thermal source to machine oil and body preheating, motor is difficult to start, the low machine oil thickness that causes of oil temperature during because of startup, poor mobile performance impels the main oil gallery oil pressure too high not in place with each friction lubricating; 2. common combustion gas supercharged engine needs the increase external equipment that certain preheating temperature rise is carried out in air inlet in order easily to start when starting, and instrument is many, and operation is many; 3. common combustion gas supercharged engine is in when operation, and the gas temperature after the supercharging is high, even hang down intake temperature with what single cooling unit was equipped with that large flow water pump and one-level intercooler also be difficult to drop to setting, and DeGrain, cost is higher; 4. the cooler intercooler of common combustion gas supercharged engine is single stage cooling, is that single cold side medium is lowered the temperature to hot side gas, and the high temperature circulation water that does not take full advantage of motor self cools off for the first time, does not reach profound cooling effect.
Summary of the invention
The purpose of this utility model provides a kind of engine booster air inlet twin-stage cooling mechanism, adopt twin-stage intercooler, high and low temperature multi-fan water tank heat exchanger, high and low temperature thermostat composite structure, the shortcoming or the deficiency that effectively overcome or avoid existing in the above-mentioned prior art.
Engine booster air inlet twin-stage cooling unit described in the utility model comprises motor, one-way valve, high temperature thermostat, twin-stage intercooler, high temperature multi-fan water tank heat exchanger, machine oil cooler, low temperature multi-fan water tank heat exchanger, electronic low temperature thermostat, cooling-water temperature sensor, gas temperature sensor.Described motor is connected with one-way valve, high temperature thermostat, twin-stage intercooler respectively, high temperature multi-fan water tank heat exchanger one end is connected with the high temperature thermostat, the other end is connected with machine oil cooler, twin-stage intercooler 4 in turn, low temperature multi-fan water tank heat exchanger 7 is connected with electronic low temperature thermostat 8, twin-stage intercooler 4, and twin-stage intercooler 4 is connected with the charge inter cooling inlet end.
Wherein, described twin-stage intercooler forms an integral body by High-temperature cooling one-level cooler and low temperature refrigeration secondary coolers.Described electronic low temperature thermostat and one-way valve, twin-stage intercooler parallel join.Described cooling-water temperature sensor is installed on respectively between twin-stage intercooler and one-way valve, the high temperature thermostat, on the pipeline between twin-stage intercooler and the machine oil cooler, between high temperature multi-fan water tank heat exchanger and the oil cooler.Described gas temperature sensor is installed on respectively on the pipeline between twin-stage intercooler and charge inter cooling inlet end, twin-stage intercooler and the motor.
The utility model has following advantage compared with prior art:
1, realized in the situation that when starting not by external equipment to oil preheating, increase oil temperature improve mobile, thereby reduce effectively lubricated each friction pair of the too high phenomenon of main oil gallery oil pressure;
2, realized in the situation that when starting not by external equipment to charge heating, impel the easy ignition trigger of motor;
3, when moving, realized by motor that the high temperature circulation water that takes full advantage of motor self cools off high-temperature gas for the first time through high temperature one-level cooler, first cooled gas is cooled off again through the low temperature secondary coolers by low-temperature circulating water again, reached profound cooling effect, effectively reduce intake temperature, improved density of the induced air, thereby the realization lean combustion improves engine power performance;
4, described cooling unit and motor are supporting, compact structure, perfect performance;
