BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic cross-sectional view of a mobile power supply vehicle according to a first embodiment, wherein 1 is a vehicle composed of a one-box car, and 2 and 3 are doubles that partition the inside of the vehicle 1 back and forth to form a cab 4 and a luggage compartment 5. A rear protruding portion 3a protruding rearward is provided at a lower portion of the rear heat shield wall 3. An air chamber 6 is formed between the heat shield walls 2 and 3. 7 is a generator provided in the luggage compartment 5, 8 is provided in front of the generator 7 in the luggage compartment 5, an engine for driving the generator 7, and 9 is provided in front of the engine 8 in the luggage compartment 5. A radiator fan 10 that is provided and driven by the engine 8 is a radiator that is provided in front of the radiator fan 9 in the luggage compartment 5 and circulates cooling water with the engine 8.

The front end of the radiator 10 substantially coincides with the rear end of the rear protruding portion 3a of the heat shield wall 3, and the rear end of the rear protruding portion 3a has a radiator 10 inside the cargo room 5 above the rear end. A partition wall 11 is provided for partitioning the front and rear except for the part. 12 is a space formed between the heat shield wall 3 and the partition wall 11, 13 is an exhaust port provided above the space 12, 14 is a lid for preventing rainwater from entering the exhaust port 13, and 3b is a shield. A communication hole provided to communicate with the space 12 above the hot wall 3;
Reference numeral 15 denotes an intake port provided at the upper rear end of the luggage compartment 5, reference numeral 16 denotes a fuel tank provided at a lower enlarged portion in the air chamber 6, and supplies fuel to the engine, and reference numeral 17 denotes a fuel tank 16 at the bottom of the air chamber 6. Are a plurality of intake ports provided around the periphery.

In the above configuration, the generator 7 generates power by driving the engine 8 and is distributed via high-voltage distribution lines and service lines. The radiator fan 9 also rotates by driving of the engine 8 and blows air to the radiator 10, whereby the engine 8 is cooled. The air blown to the radiator 10 is heated by cooling the radiator 10 to form a space 12.
And is discharged from the exhaust port 13.

[0010] The heated air is supplied to the rear heat shield wall 3.
, The air in the air chamber 6 is warmed. Therefore, the air in the air chamber 6 is lightened and rises, enters the space 12 through the communication hole 3b, and is exhausted from the exhaust port 13. As a result, cool air is sucked from the intake port 17 and rises in the air chamber 6 through the periphery of the fuel tank 16.

In the first embodiment, since the cool air always flows during the operation in the air chamber 6 as described above, heat is hardly transmitted to the operation room 4 through the heat shield wall 2. Therefore, the thickness of the heat shield walls 2 and 3 can be reduced, and the weight and space can be reduced.
Also, since the fuel tank 16 is always wrapped in cold air, no special heat insulating material is required, and since the fuel tank 16 is provided in a dead space, that is, an enlarged portion below the air chamber 6, the weight and the space are also reduced. Can be reduced.

Second Embodiment FIG. 2 is a schematic sectional view of a main part of a mobile power supply vehicle according to a second embodiment. Reference numeral 18 denotes one end attached to the communication hole 3b of the heat shield wall 3 and penetrates the partition wall 11; The other end is the same as the first embodiment in the air duct opened in the blowing direction of the radiator fan 9.

In the second embodiment, since the air duct 18 is provided, the ventilation in the air chamber 6 is further activated by the suction effect of the radiator fan 9 and the effects of the first embodiment can be further enhanced.

[0014]

As described above, according to the first aspect of the present invention, the heat shield wall between the operator's cab and the cargo room is doubled to form an air chamber therebetween, and the rear heat shield wall is formed. A lower projecting portion is provided at the lower portion to form a lower enlarged portion in the air chamber, a fuel tank is provided at the lower enlarged portion, an intake port is provided at a bottom portion around the fuel tank, and an exhaust port is provided at an upper portion of the air chamber. Since the communication hole is provided, cold air flows into the air chamber during operation, so that the thickness of the heat shield wall can be reduced, and the weight and space can be reduced. Also, the fuel tank is surrounded by cold air and requires no special heat insulating material. Further, since the fuel tank is provided in the dead space, the weight and the space can be reduced.

According to a second aspect of the present invention, the other end of the air duct, one end of which is attached to the upper communication hole of the air chamber, is opened in the direction in which the radiator fan blows air. The flow of indoor air can be further activated, and the effect of claim 1 can be further increased.
