ある。2. Description of the Related Art When the ambient temperature is high, such as in summer, the temperature in a gasoline tank rises and gasoline stored in the gasoline tank evaporates, generating gasoline vapor. If this gasoline vapor is released to the atmosphere as it is, not only the apparent fuel consumption rate will deteriorate due to the decrease in gasoline in the gasoline tank, but also it may cause environmental pollution due to hydrocarbons (HC) harmful to the human body. There is.

置を示している。[0003] For this reason, conventionally, gasoline vapor generated by gasoline vaporization in a gasoline tank is collected by a canister filled with activated carbon and sent to a combustion chamber of an engine. Various types of gasoline cooling devices that condense and liquefy by cooling and return to the inside of a gasoline tank have been considered. 9 to 10
The gasoline cooling system disclosed in Japanese Patent Application Laid-Open No. 61-102315 is shown among gasoline cooling systems conventionally considered.

下させるのに利用するものである。This gasoline cooling device is provided in a gasoline return pipe 1 for returning excess gasoline, which is not taken into an engine (not shown) by a pressure regulator, from gasoline taken out of a gasoline tank to the gasoline tank. And is used to lower the temperature of the surplus gasoline.

にしている。That is, the surplus gasoline rises in temperature by passing through a high-temperature engine room in addition to adiabatic compression by a pump for sending out gasoline. The temperature in the tank rises, and gasoline vaporization is accelerated. Therefore, the surplus gasoline is cooled by the gasoline cooler 2 provided in the middle of the gasoline return pipe 1, and the temperature rise of the gasoline stored in the gasoline tank is suppressed, thereby suppressing the gasoline evaporation itself. .

を低下させる。The gasoline cooler 2 is configured as shown in FIG. The refrigerant sent from the condenser 3 shown in FIG. 9 and passed through the reservoir 4 passes through expansion means 6 (FIG. 9) such as an on-off valve 5 and an orifice, and then is jetted into the cooling vessel 7. It evaporates and lowers the temperature in the cooling container 7.

の温度が上昇する事が防止される。An intermediate portion of the gasoline return pipe 1 is disposed in the cooling container 7 in a state of being folded back into a U-shape, and radiation fins 8 are provided on an outer peripheral surface thereof. For this reason, the temperature of the gasoline returned to the gasoline tank through the gasoline return pipe 1 decreases, and the temperature of the gasoline stored in the gasoline tank is prevented from rising due to the surplus gasoline.

う原因となる。However, in the case of such a gasoline cooling device described in Japanese Patent Application Laid-Open No. 61-102315, as long as the temperature of the surplus gasoline is high, regardless of the load on the air conditioner, the on-off valve 5 is not required. Is released, and depending on the conditions, it may not be possible to sufficiently cool the interior of the vehicle interior, which may cause a loss of comfort.

る。For example, when the engine speed is low, such as during idling, the surplus gasoline sent to the gasoline cooler 2 through the gasoline return pipe 1 despite the small amount of refrigerant discharged from the condenser 3. The amount increases. Further, since the condition that the temperature of the surplus gasoline rises and the condition that the cooling load in the cabin increases become almost the same, immediately after the temperature of the surplus gasoline rises, the refrigerant is supplied to the gasoline cooler 2.
If it is sent to the car, it will not be possible to sufficiently cool the interior of the car.

い。The cooling load is detected by a temperature sensor or the like for detecting the temperature in the vehicle compartment. When the cooling load is high, the on-off valve 5 is closed regardless of the temperature of the surplus gasoline, so that Although cooling can be sufficiently performed, it is not preferable because excess gasoline cannot be cooled instead, and the amount of evaporation of gasoline increases.
