, (23+1) due to the temperature drop of each cooling surface of both cooling fins (24a).

(24+)) is lowered, and the temperature of the heat generating surfaces of the electronic cooling elements (23a) and (23+1) is increased, so that the temperatures of the plates (22a) and (22b) are brought up to the same level, and the Heat conductive plate (22+'L).

1'221]) is transferred to the gold JAM body and both radiation fins (26aiC2611) of the inner case 7, Q,';) which are joined to each other.

When the fan (a) is driven, as mentioned above, an air flow is generated from the bottom to the top of the dehumidifying passage (18) and the cooling passage (j), and the air flow is generated in the dehumidifying passage (18). In this case, the air flowing into the inner case (dehumidification passage #Q8 from the lower end opening of the first section) first flows through both cooling fins (24a) and (24).
The water vapor contained in the air condenses into water and is discharged downward, and the air from which moisture has been removed becomes dry air and moves toward - to both heat dissipating fins ( 2(fi), (261) is cooled and warmed, and is further warmed by absorbing heat from the inner surface of the metal cylinder (10) and heat from the power supply transceiver,

Predetermined dehumidification is performed.

Therefore, according to the embodiment described in tiiJ, the outer case (
14) and the inner cane θ frame, it is possible to form two passages (18), (11) for dehumidified air and for cooling air, and also to form heat conductive plates (22a), (11).
The heat is transferred to the heat dissipation fins (26a), (261) and the metal cylinder (1() of the inner case (lυ) through the heat dissipation fins (26a), (261) and the inner case (lυ), respectively.
Since the heat from the heat generating surface of the cooling fins (24a) can be released to the incoming air of both passages 08)

(2411) has a large cooling effect υ, which can improve dehumidification performance, and moreover, the fan 1
21') can increase the amount of air entering the double-sided passageway (11111, (l), which improves the heat dissipation effect and further improves the dehumidification performance.

However, in the dehumidifying passage (08) and the cooling passage (I9), the airflow from the bottom to the top can be formed by natural convection, so energy saving can be achieved, and when the fan (1) is driven, only one fan ( 4) double-sided road (Tao).

Since airflow can be formed in each of the 01 and 01, there is no need to use two fans, one for blowing air to the cooling surface and the other for heat radiation, as in the past, reducing power consumption and failure rate. It is possible.
