In the conventional control box which is simply provided with a heat radiating plate on the outer circumference, it serves to radiate the internal heat, but in the winter when the difference between the internal temperature and the external temperature is remarkable, the heat is radiated. The plate is cooled too much by the outside air, and dew condensation occurs inside the heat sink, that is, inside the box. Occurrence of this dew condensation sometimes drops on the electronic devices and circuits inside the box, which also causes the occurrence of defects. Also, in winter, if the heat sink is cooled too much, the heat radiation by the heat sink will increase, and the temperature inside the box will drop below the proper temperature, which may adversely affect electronic devices and circuits. It was

In general, heat generated from the electronic equipment, the power supply device, the circuit, etc. housed inside the box (1) is radiated to the outside of the box (1) from the upper heat dissipation plate (2), and the inside of the box (1) is It is kept at a suitable temperature. However, when the outside air temperature decreases in winter, the heat sink (2) is overcooled by low temperature outside air, and a considerable difference occurs between the temperature inside the heat sink (2) and the inside of the box (1). Condensation is generated on the inside of the cover, but in this state, the heat-sensitive driving body of the automatic opening / closing means (4) senses the outside temperature and closes the opening / closing lid (3b) of the lid body (3). As a result, the inside of the lid (3) is shielded from the outside air, the temperature of the heat sink (2) inside the lid (3) rises, the temperature difference inside the box (1) also decreases, and the condensation on the heat sink (2) is reduced. It prevents the occurrence. When the temperature inside the lid (3) exceeds a certain level, the heat-sensitive driving body of the automatic opening / closing means (4) again operates to open the opening / closing lid (3b) and the heat sink (2).
Is cooled by the outside air, and the heat in the box (1) is radiated. After that, this is repeated to prevent dew condensation on the heat sink (2) and adjust the temperature inside the box (1).
