With the popularization of automobile products, automobile applications are very wide in all regions of the world, whether in tropical or cold regions. The temperature in tropical areas is generally higher, and reaches 30 ℃ or above. For an automobile engine, the power performance of the engine is determined by the air inlet temperature of the engine, and the vehicle using experience of a user is directly influenced. The lower the intake air temperature, the better the engine power performance, i.e., the better the user experience. Because the air intake of the current automobile engine is mainly directly sucked from the ambient air, when the automobile runs at a higher ambient temperature, the temperature of the air sucked by the engine is naturally higher, and the difficulty of controlling the air intake temperature of the engine to be at a lower level is very high.
CN 201250698Y discloses an intake air cooling device for an automobile engine, which adds a heat exchanger assembly between an air filter and a throttle part, and applies the principle that an air conditioning refrigerant forms heat exchange with air in the heat exchanger to achieve the purpose of reducing the intake air temperature of the engine and improving the performance of the engine.

However, in the running process of the automobile, fluctuation exists, so that the cooling liquid overflows from the air guide pipe, the filtering efficiency of the filtering device is influenced, the cooling effect of the cooling liquid is also influenced, and the problems of unstable cooling and short service life exist. Meanwhile, in the process that hot air passes through the cooling liquid, moisture in the cooling liquid is taken away certainly, so that the service life is shortened, and the replacement cost of the air filter is increased. In addition, the amount of the cooling liquid contained in the air filter is limited, so that the cooling effect of the cooling liquid is certainly greatly reduced when the automobile runs in a tropical environment or for a long time, the purpose of cooling the air inlet of the engine cannot be achieved, and the performance of the engine is influenced.
