Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device mounting structure for an artificial satellite, and more particularly to a device mounting structure that facilitates device layout design.

[0002]

2. Description of the Related Art Conventionally, in a device mounting structure of an artificial satellite, a device, a waveguide, a coaxial cable and a harness are mounted on a single panel surface. Also, a heat pipe is mounted inside the panel
Equipment / heat pipe panel system.

FIG. 2 is an exploded perspective view showing an example of a conventional artificial satellite device mounting structure. High-heat generating equipment is equipped with heat pipes / heat pipe panels 1 and 2
It will be installed. However, the low heat generating device is mounted on the device panel 3 that does not require a heat pipe.

A waveguide 5, a coaxial cable 6 and a harness 7 for connecting the devices 4 mounted on the device panel surface are also arranged on the same surface.

The equipment / heat pipe panel 1 and
In order to dissipate the heat generated by the equipment in 2 , the heat pipe 9 is embedded in the panel to disperse the heat in the panel and release it to outer space.

[0006]

In the conventional equipment mounting structure of the artificial satellite, since the equipment, the waveguide, the coaxial cable, the harness, and the heat pipe are arranged on the same panel surface,
Interference between the screw position where the equipment, waveguide, and harness are attached to the panel and the heat pipe, and interference between the coaxial cable route and the harness route become problems. I could not proceed in parallel.

An object of the present invention is to provide a device mounting structure that facilitates the layout design of devices mounted on a panel, a waveguide, a coaxial cable, a harness, and a heat pipe.

SUMMARY OF THE INVENTION The present invention provides a panel with:
Equipment, waveguides, coaxial cables, harnesses, in the device mounting structure of the satellite that implements the heat pipe, the machine
Mounted the vessel, waveguide, coaxial cable, and harness on both sides.
Mount the equipment panel and the heat pipe, and
Equipped with a heat pipe panel placed facing the flannel
The device panel and the heat pipe panel are
It is characterized by being connected by a member having good conductivity .

[0009]

In the device mounting structure of the artificial satellite of the present invention, a panel for mounting the heat pipe is separately provided to avoid interference with the device, the waveguide, the coaxial cable and the harness. Also, the equipment, waveguide, coaxial cable, and harness that were conventionally mounted on one side of the panel are mounted on both sides. For example, the equipment and the harness are mounted on one surface, and the waveguide and the coaxial cable are mounted on the other surface to avoid interference between the coaxial cable and the harness.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is an exploded perspective view showing an embodiment of the present invention. In the device mounting structure of this embodiment, the device panel 1
Only the device 4 and the harness 7 are mounted on the inner surfaces of 3 and 14 . Only the waveguide 5 and the coaxial cable 6 are mounted on the outer surfaces of the device panels 13 and 14 .

The connection between the device 4 and the waveguide 5 and the coaxial cable 6 is made by partially forming through holes in the device panels 13 and 14 .

The heat pipes 8 and 9 are mounted on the heat pipe panels 10 and 11, respectively.

The device panels 13 and 14 are assembled to the heat pipe panels 10 and 11 provided on the outside of these panels with a coupling fitting 12 having good heat conduction.

The low heat generating device is mounted on the device panel 3 which does not require a heat pipe as in the prior art.

[0016]

As described above, in the device mounting structure of the artificial satellite according to the present invention, by disposing the panel for disposing the heat pipe separately, the device disposition on the device panel,
The interface with the heat pipe layout is simplified, and design work can be performed in parallel.

Further, after the arrangement of the equipment is decided, an interface is taken by a connecting metal fitting between the equipment panel and the heat pipe panel, and the heat pipe panel can be standardized.

Since the equipment and the harness are mounted on the inner surface side of the equipment panel and the waveguide and the coaxial cable are mounted on the outer surface side,
Since there is no interference between the coaxial cable and the harness, they will be connected by the shortest route, reducing electrical loss and reducing weight. In addition, the mounting area of the device can be wide.
