Abstract

PURPOSE:To eliminate the need of a duct provided in the upper part of a radiator, to miniaturize and lighten an outdoor device, to simplify a waterproof structure and to lower a cost by disposing a connection line between plural heating elements through the clearance of the radiator. CONSTITUTION:The connection line 4 is inserted from the small hole 9 of a side face plate 8 to the clearance of a radiation fin, the end face of the radiation fin clearance where the connection line 4 is passed through is sealed by sealing plates 10 and 11 and the heating elements 1 and 2 are waterproofed and sealed by space composed of covers 6 and 7 and the side face plate 8. The heat of the heating elements 1 and 2 dissipated to the radiator 3, transmitted from the radiator 3 to air further and transmitted into the air. Since the connection line 4 for mutually connecting the heating elements 1 and 2 is disposed through the clearance between the radiation fin inside the radiator 3 and the different radiation fin, the need of a special structure such as the duct or the like for passing through the connection line 4 to the outside of the radiator 3 is eliminated and this outdoor device is miniaturized and made light in weight. Also, the string waterproof structure is formed by the simple structure of closing both ends of the fin and the manufacture cost of the outdoor device is lowered.

This transmitting device includes a heating element 1 that is a traveling wave tube, a heating element 2 that is a power supply for supplying power to the traveling wave tube, a radiator 3 that dissipates heat of the heating elements 1 and 2, and heating elements 1 and 2. And a connecting line 4 for supplying the output power of the heating element 2 to the heating element 1, a blower 5 for sending cooling air to the discharger 3, and covers 6 and 7 for covering the heating elements 1 and 2, respectively.

The heating element 1 and the heating element 2 are originally electrically integrated. However, in order to secure a cooling surface for the heating element of the radiator 3, the radiator 3 is divided into two parts. It is fixed to the two cooling surfaces and is electrically connected by the connection line 4.

[0004] At the upper part of the radiator 3, there is provided a duct 3a through which the connection wire 4 passes and which protects the connection wire 4. As shown in FIG. 4, there are three connection lines, and these three connection lines supply required power from the power supply of the heating element 2 to the traveling wave tube of the heating element 1. However, in FIG. 3, in order to simplify the drawing, the connecting lines 4 are collectively drawn.

[0005]

However, as described above, the conventional outdoor device has a duct 3 above the radiator 3.
Since a is provided, the outer shape of the apparatus becomes large and the weight is inevitably heavy. Also, a duct 3a provided above the radiator 3
In the structure in which the connection wire 4 is passed through the portion 6a,
There is a problem that the waterproof structure of 3a and 7a becomes complicated and the manufacturing cost becomes high.

[0006]

In order to solve the above-mentioned problems, the present invention provides the following means.

Is disposed through the gap in the radiator, the outdoor device.

In the radiator, the radiator fins are sandwiched by first and second side plates extending in parallel to each other in a direction perpendicular to the plate surface of the radiator fins, and the plurality of heating elements are arranged in the first and second radiators. Fixed to the first or second side plate,
The connection line connecting the heating element fixed to the first side plate and the heating element fixed to the second side plate is provided on the first and second side plates. The outdoor device described above, wherein the outdoor device is inserted into the gap through a hole.

[0009] First and second sealing plates facing each other provided on a plane orthogonal to the radiation fins and the first and second side plates seal both ends of the gap through which the connecting wire is passed. The outdoor device as described in the above item 1 or 2, characterized in that:

The cover is composed of a first cover fixed to the first side plate and a second cover fixed to the second side plate. Is provided with a flange, the first and second covers are in contact with the peripheral edges of the side plates by the flange, and a plurality of male screws respectively inserted into a large number of through holes provided in the flange are provided. The outdoor device as described in the above item, wherein the outdoor device is fixed to each of the side plates by being screwed into a plurality of female screws provided at the periphery.

The outdoor device as described in the above item 1 or 2, further comprising: a blower for blowing air into the gap.

[0012]

According to the present invention, since connection lines are provided at intervals between the radiating fins in the radiator, the duct 3a provided above the radiator in the conventional device becomes unnecessary, and the outdoor device can be downsized. This facilitates the weight reduction and simplifies the structure of the portion exposed to the outside air because the duct 3a is not required, thereby enabling the simplification of the waterproof structure and the reduction in cost.
