Description
Technical Field
The invention relates to the technical field of engine intercoolers, in particular to an engine intercooler device with a protection function.
Background
In order to increase the power up of the engine and reduce the fuel consumption, superchargers are increasingly used in the engine. The air temperature after the engine is supercharged reaches 130-150 ℃ and even higher, and researches show that the density of the air is increased by about 3% and the thermal efficiency of the engine is increased by about 0.5% when the air inlet supercharging temperature is reduced by 10 ℃. To achieve higher in-cylinder charge densities, increased power requires cooling of the post-charge air. The engine on the whole vehicle adopts air-air cooling, namely adopts cold air to cool the air after supercharging. In the engine bench test, a water-air intercooler is often adopted, and the control of the air temperature after the engine is supercharged is realized through circulating cooling water.
The intercooler is typically only visible in a vehicle in which the supercharger is installed. Because the intercooler is actually a turbocharger accessory, the intercooler is used for reducing the temperature of high-temperature air after supercharging so as to reduce the thermal load of the engine, improve the air inflow and further increase the power of the engine. For supercharged engines, the charge air cooler is an important component of the supercharging system. Whether it is a turbocharged engine or a supercharged engine, an intercooler needs to be installed between the supercharger and the intake manifold.
Along with the release of the national sixth-stage emission standard, the heavy-duty vehicle engine test intercooler device has higher requirements: before the chiller test, the cooling fluid of the intercooler device is greater than 20 ℃, and the cooling fluid is not allowed to change in the whole test cycle, and in addition, the cooling fluid flow rate is kept unchanged after the temperature after the intercooler device is cooled at the rated working point is stable. The engine performance needs to be tested during production, the supercharged air inlet needs to be cooled during engine test, and an intercooler of the existing engine has no protection function and is low in efficiency.

When the electronic control unit 2 works, the water return regulating valve 12 is controlled to regulate the water quantity according to the threshold value set by the air outlet temperature sensor 7, so that the air outlet temperature is stabilized in a set range. The method comprises the following steps: when the gas outlet temperature sensor 7 detects that the gas temperature is lower than the minimum value of the set value, the electronic control unit 2 controls the water return regulating valve 12 to be closed so as to slow down the heat exchange speed of the hot air and the cooling water.
