ている。As shown in FIG. 3, a temperature sensor 23 is attached to the outer surface of the outer panel 1, that is, the anti-icing surface 1a, and the output of this temperature sensor 23 is input to a controller 24. and,
The opening degree of a flow control valve 25 installed in the duct 7 is controlled by a command from the controller 24.
他の構成は第4図及び第5図に示す従来のものと同様で
あり対応する部材には同し符号が付されている。The rest of the structure is similar to the conventional one shown in FIGS. 4 and 5, and corresponding members are given the same reference numerals.

When the temperature of a drops to a predetermined value, for example, 2° C. or less, the flow control valve 25 is opened by a command from the controller 24, and the heated air in the heated air source s passes through the duct 7 and the flow control valve 25 into the manifold 4. The heat enters and is injected from the nozzle 11 onto the inner surface of the planar heat pipe 20.

る。When the inner surface of the heat pipe 20 is heated, this heat is transferred to the outer surface of the heat pipe 20 via the working medium enclosed within the heat pipe 20 and then through the outer surface 45.1 to its outer surface, i.e. , is transmitted to the anti-icing surface 1a and heats it. The air whose temperature has been lowered by heating the heat pipe 20 is discharged to the outside of the cavity 3 through the exhaust hole 2.

制御することにより防氷面1aの温度を常時一定の温度
例えば2℃に維持できる。The temperature of the anti-icing surface 1a is constantly detected by the temperature sensor 23, and by automatically controlling the opening degree of the flow rate control valve 25 according to this temperature, the temperature of the anti-icing surface 1a is always kept at a constant temperature, for example, 2°C. Can be maintained.

低の温度となるように加熱空気を供給すれば良いので、
エネルギの浪費を防止できる。When ice adheres unevenly on anti-icing surface 1a,
Even if the heat load on surface a becomes uneven, the planar heat pipe 20 transfers the heat from areas with low heat load to areas with high heat load, so that the entire anti-icing surface 1a can be waterproofed. It is only necessary to supply heated air so that the temperature of the anti-icing surface 1a reaches the minimum temperature necessary and sufficient for waterproofing.
Energy waste can be prevented.
上記実施例においては、外板1の内面に面状のヒートパ
イプ20を取り付けたが、面状のヒートパイプ20の外
面を防氷面1aとすることもできる。In the above embodiment, the planar heat pipe 20 is attached to the inner surface of the outer panel 1, but the outer surface of the planar heat pipe 20 can also be used as the anti-icing surface 1a.
また、上記実施例においては、ヒートパイプ20の内面
に加熱空気を吹き付けることによって加熱しているが、
電気ヒータ等によって加熱することもできる。Furthermore, in the above embodiment, heating is performed by blowing heated air onto the inner surface of the heat pipe 20.
Heating can also be done with an electric heater or the like.

段を設けたため、防氷面の熱負荷が不均一となってもこ
れを面状のヒートパイプによって加熱することによって
防氷面の温度分布を均一化することができる。Furthermore, when the anti-icing surface 1a is small or when the distribution of heat load on the anti-icing surface la is relatively uniform, the present invention can reduce the temperature inside the anti-icing surface over its entire surface. Since the heat pipe is equipped with a beat pipe and a means for heating the inner surface of the heat pipe, even if the heat load on the anti-icing surface is uneven, the heat load on the anti-icing surface can be heated by the planar heat pipe. Temperature distribution can be made uniform.
この結果、防氷面に局部的加熱不足部分や局部的高温部
分の発生を防止して防氷面の全面を確実に防水できると
ともにエネルギの浪費を防止できる。As a result, it is possible to prevent the occurrence of locally underheated areas or locally high temperature areas on the anti-icing surface, thereby making it possible to reliably waterproof the entire surface of the anti-icing surface and to prevent wastage of energy.
