御される。(Operation) When the cooling water temperature is equal to or higher than the set temperature, the liquefied refrigerant supplied to the evaporating section through the open / close valve and the water supply pipe from the condensing section and the refrigerant reservoir to the evaporating section flows through the cooling water flowing through the cooling water chamber in contact with the evaporating section. At the same time as the gas is vaporized by heat, the cooling water is cooled by the heat of vaporization and supplied to the internal combustion engine cooling unit.When the cooling water temperature is lower than the set temperature, the on-off valve is in a closed state, and the refrigerant liquefied by the condensing unit is a refrigerant. Accumulate in the pool,
Since the cooling water is not supplied to the evaporator, the cooling water is supplied to the internal combustion engine cooling unit without exchanging heat with the cooling water in the cooling water chamber in the evaporator. Thus, the cooling capacity of the cooling device of the internal combustion engine is controlled by the opening / closing control of the on-off valve in the same manner as in the related art without switching the cooling water flow path as in the related art.

It flows through the annular portion 13a. A vapor conduit 18 communicating with the condensate tank 17 is provided above the refrigerant tank 16. Above the condensate tank 17, a radiator 19 is provided. Radiator 19
Is composed of a plurality of tubes 20 communicating with the condensate tank 17, corrugated fins 21 arranged between the tubes 20, and shrouds 22 and fans 23.

An on-off valve 25 is provided. The on-off valve 25 is closed when the temperature of the cooling water of the engine is lower than the set temperature, and is opened when the temperature of the cooling water is higher than the set temperature. This on-off valve
The open / close control method of 25 may be performed by a temperature sensing unit directly provided in the open / close valve 25, or may be performed by receiving a signal from another water temperature sensor.

20 is communicated in a liquid-tight manner, the inside of which is depressurized to a state close to a vacuum, and an appropriate amount of refrigerant (for example, water) is sealed. Further, the capacity of the condensate tank has a capacity capable of accommodating the entire amount of the enclosed refrigerant.
以上に示すように、エンジンの冷却水とサーモサイフ
オン部15内の冷媒とは異なる閉回路系の流路を循環す

15内の冷媒の相変化を伴つて外気へ放熱される。In the above configuration, when the temperature of the cooling water is higher than the set temperature, the on-off valve 25 is in the open state.
The refrigerant in 17 flows into the refrigerant tank 16 through the water supply pipe 24. Since the ambient pressure of the refrigerant is close to vacuum, the saturation temperature of the refrigerant is sufficiently lower than the set temperature, so that the refrigerant takes heat of the cooling water flowing through the annular portion 13a, and the refrigerant starts to evaporate. This steam passes through a steam conduit 18 and enters a condensate tank 17
Flows into the tube 20, and is cooled and condensed by the action of the corrugated fin 21 and the fan 23. The condensed refrigerant drops due to gravity, returns to the condensate tank 17, and flows into the refrigerant tank 16 again through the water supply pipe 24. The heat generated by the engine 11 due to this repetition is transferred to the thermosyphon section.
Heat is released to the outside air with the phase change of the refrigerant in 15.

媒が放熱部19で凝縮した後は、全ての冷媒が復水タンク
17の底部に溜まり、冷媒タンク16は空となるために冷却
水の熱を奪うことができず冷却水は冷却されない。On the other hand, when the temperature of the cooling water is lower than the set temperature, the flow of the refrigerant from the condensate tank 17 to the refrigerant tank 16 is shut off because the on-off valve 25 is in the closed state. Therefore, after the evaporated refrigerant is condensed in the radiator 19, all the refrigerant is condensed in the condensing tank.
Since the refrigerant tank 16 is accumulated at the bottom of the cooling water tank 17 and becomes empty, the heat of the cooling water cannot be removed and the cooling water is not cooled.

30の側断面の概略図を示す。Next, a description will be given of a cooling device for an internal combustion engine according to a second embodiment of the present invention. However, since only the shapes of the refrigerant tank and the cooling water chamber are different from those of the first embodiment, the other portions are the same as those of the first embodiment. The description is omitted by assigning the same reference numerals as in FIG. FIG. 3 shows a cooling device for an internal combustion engine according to a second embodiment of the present invention.

ャビテーションの発生が防止され、当該冷却装置の信頼
性を向上することができる。As described above, according to the present invention, it is possible to control the cooling capacity of the cooling device of the internal combustion engine in the same manner as before by controlling the opening and closing of the on-off valve without switching the cooling water flow path unlike the related art. The need for a bypass channel and a thermostat valve, which are required, can be eliminated. Thus, the capacity of the water pump can be reduced, the horsepower loss of the internal combustion engine can be reduced, cavitation can be prevented from occurring, and the reliability of the cooling device can be improved.

ことができ、冷媒の熱劣化を防止することができる。Further, when the cooling water temperature is equal to or lower than the set temperature, the refrigerant is not supplied to the evaporator in contact with the cooling water chamber by the on-off valve, so that the time during which the refrigerant is exposed to the heat of the cooling water can be shortened. In addition, thermal deterioration of the refrigerant can be prevented.
