<p>PURPOSE:To eliminate necessity of heat-radiating fin and to miniaturise an apparatus by connecting an upper metallic cylinder with a lower resinous cylinder in one body to construct a main body of a dehumidifying apparatus and radiating the heat of a heating surface of an electronic cooling element conducted to the metallic cylinder through a heat-conducting plate. CONSTITUTION:Main body 26 of a dehumidifying apparatus connecting an upper metallic cylinder 27 with a lower resinous cylinder 28 in one body is installed in such as a power board. When a power source transformer 36 is operated, the temp. of a cooling fin 34 is lowered by the lowering of the temp. of a cooling surface of an electronic cooling element 33, and the temp. of a conductive plate 32 is elevated by the elevation of temp. of the heating surface, and the heat is conducted to the metallic cylinder 27 joined to the upper part of the conductive plate 32 and radiated. The air in the top of an air passage 31 is expanded by being warmed by the heat of the transformer 36 and the metallic cylinder 27 and discharged into the main body of the power board through a discharge port 30. Air of high humidity in the main body of the power board flows in from a suction port 29 by the pressure drop in the air passage 31, cooled by a cooling fin 34 to reduce the water content, warmed at the top of the air passage 31 and discharged from a discharge port 30. Condensed water is discharged from a water discharge port 39.</p> |
