A heat insulating device for an engine compartment and a passenger compartment of a car is arranged on a separating plate between the engine compartment and the passenger compartment and comprises a thin pipe array, an auxiliary air filter, an auxiliary air inlet pipe I, an auxiliary air inlet pipe II, an auxiliary pipeline connecting port and a temperature-control solenoid valve device, wherein one end of the thin pipe array is connected with the auxiliary air inlet pipe I by the aid of a transitional coupling I; the auxiliary air inlet pipe I is connected with one end of the auxiliary air filter; the other end of the auxiliary air filter communicates with the atmosphere; the other end of the thin pipe array is connected with the auxiliary air inlet pipe II by the aid of a transitional coupling II; and the auxiliary air inlet pipe II is connected with an original air inlet pipe of an engine by the aid of the auxiliary pipeline connecting port. Under the effect of negative pressure in the air inlet pipe of the engine, air in thin pipes of the thin pipe array of the heat insulating device flows, so that heat insulation of the engine compartment and the passenger compartment is realized. With the adoption of the heat insulating device, on the premise that the load of the engine and air resistance of the whole car are not increased, heat of the engine compartment cannot be transferred to the passenger compartment, so that the problem of reduction of riding comfort of the passenger compartment due to transfer of the heat of the engine is solved; meanwhile, the heat of the engine compartment is prevented from being transferred to the passenger compartment, and thus the energy consumption of an air conditioner of the car can also be reduced to a certain extent.

The invention provides a seawater utilizing system for artificial influencing dispersal microclimate of coastal city which comprises a seawater post-treating apparatus, a underground sea water pump, a seawater pre-treating apparatus, a thermal insulation seawater reservoir, a seawater pressure pump, a heat exchanger, an air-conditioning unit, a sprinkling tower, an artificial lake network system, and a river piping system. The system can substantially reduce the energy consumption for air-conditioning in a city while protect the environment at the same time.
