Referring to the temperature control in the electrical distribution box 40 and the communication box 40 'through the electrical distribution box and the communication box installation cold and hot holding device (A) according to the present invention as follows.

As shown in FIG. 7, the cold distribution apparatus A for installing the electric distribution box and the communication box according to the present invention is installed in the door of the electric distribution box 40 and the communication box 40 ′ so that the built-in part 20 is installed in the electric distribution box ( 40) and the interior of the communication box 40 ', the exterior portion 30 is located outside the electrical distribution box 40 and the communication box 40'.

In this state, the interior part 30 heats or cools the air in the electrical distribution box 40 and the communication box 40 '.

In the present invention, the sensor of the controller 35 provided in the interior part 30 continuously detects the temperature inside the electrical distribution box 40 and the communication box 40 ', and the sensor detection temperature is initially set in the controller 35. If the electrical distribution box 40 and the communication box 40 'to maintain the internal temperature outside the controller 35 is the thermoelectric element 13 and the outer portion 20 of the thermoelectric element installation portion 10 and the interior portion 30 Blowing fan (23, 33))) by applying power to operate the thermoelectric element 13 and the blowing fan (23, 33), the heating or cooling in the electrical distribution box 40 and the communication box (40 ') is made You lose.

That is, when the sensor sensing temperature of the controller 35 becomes higher than the internal holding temperature of the electrical distribution box 40 and the communication box 40 'such as in the summer, the exterior part 20 and the interior part 30 Blower fan 23, 33 blows toward the thermoelectric element 13 of the thermoelectric element installation portion 10, and at the same time the rear surface of the thermoelectric element 13 in contact with the heat sink 31 of the built-in portion 30 And the front surface of the thermoelectric element 13 in contact with the heat sink 21 of the exterior part 20 becomes a heat state, so that the interior part 30 can be in a cooling state and the exterior part 20 becomes a heating state. It becomes possible.

At this time, the blowing air from the blower fan 33 on the heat sink 31 of the built-in portion 30, while passing through the heat sink 21 in contact with the front surface of the thermoelectric element 13 in a heat generating state as shown in FIG. As shown in FIG. 4, the thermoelectric in the endothermic state is opposite to the blowing from the blower fan 23 which is heated to the heat dissipation plate 21 of the exterior part 20 discharged to the blower opening 24b of the cover 24 in a warm air state. Cooled rapidly while passing through the heat sink 31 in contact with the back of the element 13, the electrical distribution box because it is quickly propagated inside the electrical distribution box 40 and the communication box (40 ') in a cold air state through the air vent 34b of the cover 34 The air inside the 40 and the communication box 40 'can be cooled quickly.

On the contrary, when the sensor sensing temperature of the controller 35 is equal to or lower than an internal holding temperature of the electrical distribution box 40 and the communication box 40 ′ set in the winter, the exterior part 20 and the interior part 30 are winter. Blower fan (23, 33) of the fan blows toward the thermoelectric element 13 of the thermoelectric element installation portion 10, and at the same time the rear of the thermoelectric element (13) in contact with the heat sink 31 of the built-in portion 30 generates heat State and the front surface of the thermoelectric element 13 in contact with the heat sink 21 of the exterior portion 20 becomes an endothermic state, so that the interior portion 30 may be in a heating state and the exterior portion 20 may be in a cooling state. Will be.

At this time, the blowing air from the blower fan 33 on the heat sink 31 of the built-in portion 30 rapidly passes through the heat sink 21 in contact with the front surface of the thermoelectric element 13 in the heat absorbing state, as shown in FIG. As shown in FIG. 4, the thermoelectric in the heat generating state is opposite to the blowing from the blower fan 23 which is cooled to the heat sink 21 of the exterior part 20 discharged to the blower opening 24b of the cover 24 in a cold air state. The heat is rapidly heated while passing through the heat sink 31 in contact with the rear of the element 13, so that the electric power distribution box (40) is quickly propagated inside the electrical distribution box 40 and the communication box (40 ') in a warm air state through the air outlet (34b) of the cover (34) 40) and the air inside the communication box can be heated quickly.

The electrical distribution box 40 and the communication box 40 'installed with the electrical distribution box and the communication box installation cold / hot holding device A according to the present invention can easily set the internal temperature of the four seasons without an administrator's residence through the operation process as described above. It can be maintained to ensure that the parts can be damaged or malfunction due to overheating or cooling.

Meanwhile, in the present invention, since the condensation may occur in the heat sink 31 when the interior part 30 is in a cooling state, the internal parts of the electrical distribution box 40 and the communication box 40 'may be damaged or malfunction due to moisture. Can be.

However, in the present invention, the interior part 30 is provided with a drip tray 36 as shown in FIG. 5, even if condensation occurs on the heat sink 31 of the interior part 30, the condensation water flows downward to the drip tray 36. While being drained directly to the exterior portion 30 through the drain pipe 36a, it is possible to prevent damage and malfunction of the internal parts of the electrical distribution box 40 and the communication box 40 'due to moisture due to condensation.

In addition, since the rainwater may flow through the ventilation holes 24a formed in the cover 24 of the exterior part 20 in the present invention, the parts may be damaged or malfunction due to water inflow.

However, in the present invention, the blowing fan 23 of the exterior part 20 is waterproof, and as shown in FIG. 6, rainwater flows through the ventilation hole 24a formed in the cover 24 of the exterior part 20. Even if the rainwater flows into the waterproof blower fan 23, it immediately falls to the lower part and is discharged to the outside through the air vent 24b formed at the bottom of the cover 24, thereby preventing damage or malfunction of parts due to water inflow. You can do it.
