り所定時間毎に通電し発熱せしめるようにする。In the present invention, as shown in FIGS. 1 to 3, one end of a heat conduction plate 19 is fixed to the outer surface of the desiccant container 5, and the other end of the heat conduction plate 19 is bent in a U shape. The shape memory alloy coil 12 is arranged in the U-shaped space, and an electric resistance material is mixed with the shape memory alloy coil 12, and the shape memory alloy coil 12 is mixed with the electric resistance material at predetermined intervals by a timer 2. Energize to generate heat.
本発明の湿気除去装置は上記のような構成であるから形
状記憶合金コイル12の発熱温度を乾燥剤加熱用の発熱体
９より低くし形状記憶合金コイル12の最大温度を低下す
ることが出来る。Since the moisture removing device of the present invention is configured as described above, the heat generation temperature of the shape memory alloy coil 12 can be made lower than that of the heating element 9 for heating the desiccant to lower the maximum temperature of the shape memory alloy coil 12.
また、ケース１内の温度は上記形状記憶合金コイル12の
発熱によって上昇されるケース１内壁に水蒸気が結露す
