At this time, since the portion of the cooling diode heat pipe 10 inside the cooling ventilation box 11 is cooled, the cooling diode heat pipe 10 inside the box 1 moves heat as indicated by an arrow C to lower the internal temperature of the box 1. Function as a cooling box. Therefore, the cold air does not flow directly into the box 1. When the cooling is stopped, the cold air inlet valve 14 and the cold air outlet valve 16 are closed. Therefore, the cool air in the cooling ventilation box 11 is confined, and the box 1 functions as a cooling box for a long time to keep heat. At this time, heat does not flow from the cooling diode heat pipe 10 due to the function of the diode heat pipe.

When heating the inside of the box 1, the hot air inlet valve 24 and the hot air outlet valve 26 are opened, and the cold air inlet valve 14 and the cold air outlet valve 16 are closed. Warm air from an air conditioner (not shown) enters through the warm air inlet valve 24 as indicated by arrow D-E, passes through the warm ventilation box 21 and is discharged through the warm air outlet valve 26. At this time, since the portion of the heating diode heat pipe 20 inside the heating ventilation box 21 is heated, the heating diode heat pipe 20 inside the box 1 moves heat as shown by an arrow F, and the inside of the box 1 is heated. Raise the temperature to function as a heating box. Therefore, the warm air does not flow directly into the box 1. When the heating is stopped, the hot air inlet valve 24 and the hot air outlet valve 26 are closed. Therefore, the warm air of the warm ventilation box 21 is confined, and the box 1 serves as a warm box for a long time to keep heat. At this time, heat does not flow from the heating diode heat pipe 20 due to the function of the diode heat pipe.

FIG. 2 is a diagram showing the overall structure of a vehicle air conditioner. The box 1 is installed in the cab 30.

It is connected via a valve 16. Also, the air passage 3
2 and the return passage 33 and the warm ventilation box 21 provided in the box 1 are connected via a warm air inlet valve 24 and a warm air outlet valve 26, respectively. Air conditioner 3
The one cooling passage 34 is provided with an evaporator 40 for cooling, and the evaporator 40 and the cooling compressor 41 are connected by a refrigerant passage 42. Reference numeral 43 is a compressor motor, and 44 is a cooling fan motor that drives a cooling fan 45. A heating heater 46 is arranged in the other heating passage 35 of the air conditioner 31. 47 is a heating fan 4
8 is a fan motor for heating. A cooling passage 34 and a heating passage 35 are provided at a connecting portion between the air conditioner 31 and the return passage 33.
A switching valve 36 for switching between and is provided. 50 is a heating / cooling selector switch for setting the air conditioner,
The cooling side contact (C) is the compressor motor 4 for cooling.
3, the cooling air blowing motor 44, the switching valve 36, the cold air inlet valve 14, and the cold air outlet valve 16 are connected. The heating-side contact (H) of the cooling / heating changeover switch 50 is connected to the heating heater 46, the heating blower motor 47, the switching valve 36, the warm air inlet valve 24, and the warm air outlet valve 26.

When the cooling / heating switch 50 is turned on, the compressor motor 43 and the cooling air blowing motor 44 are activated, and the switching valve 36 is switched to the position shown by the solid line. At the same time, the cold air inlet valve 14 and the cold air outlet valve 16 are opened, and the warm air inlet valve 24 and the warm air outlet valve 26 are closed. Therefore, the air in the cooling passage 34 is cooled by the evaporator 40, and the cool air flows into the driver's cab 30 and the cooling ventilation box 11 as indicated by solid arrows, and the operator's cab 30 and the box 1 are cooled.

When the heating / cooling selector switch 50 is turned on, the heating heater 46 and the heating air blowing motor 47 are activated,

At the same time, the hot air inlet valve 24 and the hot air outlet valve 26 are opened, and the cold air inlet valve 14 and the cold air outlet valve 16 are closed. Therefore, the air in the heating passage 35 is warmed up by the heater 46 for heating, and the hot air flows into the cab 30 and the warm ventilation box 21 as indicated by the dashed arrow, and the cab 30 and the box 1 are heated. When the cooling / heating switch 50 is set to the neutral position, the cold air inlet valve 14, the cold air outlet valve 16, the warm air inlet valve 24, and the warm air outlet valve 26 are closed.

[0016]

Since the present invention has the above-described structure, it has the following effects. (1) Since the cool air or hot air of the air conditioner does not flow directly into the box, the odor and dust of the air conditioner will not enter the box. Therefore, drinks and the like can be kept clean. (2) Since the heating part or the cooling part of the diode heat pipe is kept warm by the ventilation box, it is possible to perform the function of cooling or keeping the inside of the warming box warm for a long time even after the air conditioner is stopped. (3) If the switching of the cooling or heating device is linked to the operation of the air conditioner of the vehicle, the switching operation of the cooling or heating device becomes easy.
