【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a rear half of a vehicle body of a vehicle, and a seat 2 is provided in a rear portion of a vehicle compartment 1. A rear shelf 3 is provided behind the seat 2, and a trunk room 4 is present on the lower surface side of the rear shelf 3. The trunk room 4 extends from the lower surface side of the riashieruf 3 to the rear part of the vehicle body.

A storage case 10 is buried in the rear shelf 3. The housing 10 has a main body intruding into the trunk room 4 and an entrance / exit opening facing the inside of the vehicle compartment 1 so that articles can be freely taken in and out of the passenger compartment 1. Is blocked by. In addition, the canned juice C is stored in the storage case 10 as an example.

On the other hand, although not shown, an engine is provided in the front part of the vehicle body, and an exhaust pipe 5 forming an engine exhaust path is extended from the engine to the rear part of the vehicle body. A muffler 6 for muffling is provided at the rear of the exhaust pipe 5.

Further, although not shown, an air passage for ventilation is formed from the vehicle compartment 1 to the trunk room 4, and the air in the vehicle compartment 1 flows to the trunk room 4 through the air passage. ing. The air that has flowed into the trunk room 4 is exhausted to the outside from the ventilation outlet 7 formed on the side surface of the vehicle body.

The muffler 6 is located at a position corresponding to the trunk room 4, and a generator 11 is attached to the muffler 6 as shown in FIG. Then, the condenser 12, the evaporator 13, and the absorber 14 are sequentially connected to the generator 11 by the pipes 20, respectively, to form an absorption type refrigeration cycle.

Here, the generator 11 recovers the heat of the muffler 6 and vaporizes the refrigerant inside. The absorber 14 has a built-in adsorbent such as zeolite and functions to absorb the gas refrigerant and liquefy it.

Among the devices constituting this refrigeration cycle, the evaporator 13 is arranged as a cooler in the storage case 10, and the absorber 14 is arranged obliquely along the seat back of the seat 2. That is, the respective devices forming the refrigeration cycle are arranged in the trunk room 4 in a state of being separated from each other.

In the trunk room 4, a duct 15 is provided from the vicinity of the condenser 12 to the ventilation outlet 7. A fan 16 is provided in this duct 15. The duct 15 and the fan 16 serve to concentrate and send the air that has flowed from the vehicle compartment 1 to the trunk room 4 to the condenser 12.

In this way, the storage 10, the generator 11, the condenser 12, the evaporator 13, the absorber 14, the pipe 20, the duct 15, and the fan 16 constitute the vehicle refrigeration system of the present invention. Next, the operation will be described. When the engine of the automobile is started, the exhaust gas of the engine is exhausted to the outside through the exhaust pipe 5 and the muffler 6.

At this time, high-temperature exhaust heat is transmitted from the muffler 6 to the generator 11, and the refrigerant inside the generator 11 is vaporized. The vaporized high-pressure gas refrigerant is sent to the condenser 12, where the heat in the air in the luggage compartment 4 is liquefied. This liquid refrigerant is sent to the evaporator 13.

In the evaporator 13, the refrigerant takes heat from the storage 10 and vaporizes it. The refrigerant vaporized in the evaporator 13 is absorbed by the absorber 14, where the heat in the air in the trunk room 4 is taken away and liquefied. This liquid refrigerant is sent to the generator 11. In this way, the absorption refrigeration cycle operates to cool the air in the storage case 10.

Further, the fan 16 is operating at the same time when the engine is started, and the air in the trunk room 4 concentrates on the condenser 12 as cooling air. The wind that has passed through the condenser 12 travels through the duct 15 as indicated by the dashed arrow in FIG. 1, and is discharged outside from the ventilation outlet 7. Therefore, the cooling efficiency for the condenser 12 is improved, and the cooling capacity of the storage case 10 can be improved.

Particularly in the summer, the air flowing from the passenger compartment 1 to the trunk compartment 4 is cooled by the cooling, so that low-temperature air is sent to the condenser 12 and the heat dissipation effect in the condenser 12 is promoted. The cooling capacity is improved. Although the container 14 is not blown with air, since it is in the trunk room 4, the heat dissipation action is similarly promoted and the cooling capacity is improved.

Further, since the generator 11, the condenser 12, the evaporator 13, and the absorber 14 that constitute the refrigeration cycle are separately arranged in the trunk room 4, they are not bulky and require a large space for installation. Never. Therefore, the space in the luggage compartment 4 can be effectively used for accommodating articles without sacrificing it. Furthermore, even a vehicle model with a small trunk room 4 can be installed without being affected by it.

Moreover, since the heat of the muffler 6 is recovered by the generator 11, it has the effect of lowering the exhaust gas temperature, and the exhaust gas can be made clean and the pollution can be reduced, and the energy saving can be achieved. ..

Further, since the temperature of the exhaust gas passing through the exhaust pipe 5 and the muffler 6 is much higher than the temperature of the engine body, it is possible to secure high energy for the operation of the refrigeration cycle, and also in this respect, the cooling capacity is high. It can greatly contribute to improvement. Although the generator 11 is attached to the muffler 6 in the above embodiment, the generator 11 may be attached to the exhaust pipe 5.
