DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carbon fiber skin heat pipe panel used as a structural panel constituting, for example, an artificial satellite.

2. Description of the Related Art FIG. 21 shows a general carbon fiber skin heat pipe panel, in which 1 is an inner skin (on the inner surface of the artificial satellite), 2 is an outer skin (the outer surface of the artificial satellite), and 3 is a heat pipe. 4 is a honeycomb core. The carbon fiber skin heat pipe panel uses a flexible 5 adhesive between the heat pipe and the skin to prevent destruction due to the difference in thermal expansion between the metal heat pipe and the skin material's carbon fiber. Generally, a structural adhesive 6 having a higher adhesive strength is used.

[0003]

However, since the adhesive strength of the flexible adhesive is inferior to that of other structural adhesives in terms of strength, it is limited to the bonding of the heat pipe to the inner skin and the outer skin. It is common to use. For this reason, in the conventional technique, the structural adhesive and the flexible adhesive are alternately set on the inner skin and the outer skin, so that it takes a long time to manufacture, and also the structural adhesive and the flexible adhesive are used. Due to the locations where the agents are in contact, they can mix and react during the curing process, reducing the adhesive strength and consequently the structural strength of the panel. In particular, when mounting equipment with high heat generation, use a heat pipe with a flange and improve the thermal efficiency by exposing the equipment mounting part of the heat pipe to the panel place.However, carbon fiber skin heat pipe panel For the above reasons, such a structure has been difficult.

The present invention has been made in order to solve such a problem. A carbon fiber material is previously bonded to the upper and lower portions of a heat pipe with a flexible adhesive, and the carbon fiber material is bonded to the inner skin with a structural adhesive. Further, the present invention provides a carbon fiber skin heat pipe panel which simplifies a manufacturing process by bonding to a outer skin and has a higher structural strength than a conventional one.

According to the present invention, the manufacturing process can be simplified, and the structural adhesive and the flexible adhesive can be prevented from being mixed in the curing process. In addition, even when considered as a sandwich structure, the inner skin of the heat pipe and the entire outer skin can be adhered with a structural adhesive, so that the structure has higher strength compared to the conventional carbon fiber skin heat pipe panel. Become.
