Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a microwave repeater, and particularly to its housing structure.

Conventionally, as shown in Fig. 1, the housing structure of a microwave repeater has a structure in which both sides of the housing are radiators 1, and inside the housing there is a microwave power amplification unit 2, which is a heating element, and a power source. Units are implemented. In particular, the microwave power amplification unit 2 must be electrically connected to the primary radiator 4 disposed relative to the parabolic antenna 3 without electrical loss. Therefore, the output of the unit 2 is placed near the outlet of the primary radiator 4 and electrically connected at the shortest distance. As a result, the heat generated by the microwave power amplification units 2 is transferred to the radiators 1 on both sides by heat pipes 5, etc., and is radiated. Therefore, the heat pipe 5 for heat transport and its attachment parts are expensive, and there are various restrictions on mounting, which hinders the progress of making the device smaller and lighter.

The purpose of the present invention is to solve the above-mentioned drawbacks and provide an inexpensive, small, and lightweight housing with good heat dissipation effect by arranging heat sinks from both sides of the housing to the parabolic antenna surface of the housing.

According to the present invention, there is obtained a microwave repeater characterized in that a radiator is disposed on a parabolic antenna fixing surface, and a parabolic antenna fixture is provided on the radiator.

Next, one embodiment of the present invention will be described in detail with reference to the drawings. FIG. 2 is a diagram showing an embodiment of the present invention, in which the heat sink 1 is arranged on the fixed surface side of the parabolic antenna 3. For this purpose, a parabolic antenna fixture 6 is attached on this heat radiator 1. In the present invention, electrical performance can be improved by arranging the power amplification unit 2 close to the parabolic antenna 3, and moreover, it can be attached directly to the radiator 1, eliminating the need for heat transport components such as heat pipes.
Another advantage is that heat is conducted from the radiator 1 to the parabolic antenna 3 via the parabolic antenna fixture 6 and radiated therefrom. As a result, in the present invention, the overall cooling efficiency of the apparatus is extremely high, and therefore a compact configuration is possible. Furthermore, this device is often used outdoors, and in this structure, the radiator section is in the shadow of the parabolic antenna, making it difficult for it to receive direct sunlight, making it an excellent heat dissipation structure.

As explained above, the present invention has the effect of providing an inexpensive, small, and lightweight housing with good heat dissipation effect by arranging the heat sink on both sides of the fixed antenna.
