Abstract: PURPOSE:To retain an apparatus on board at a designated temperature at a low cost without pollution by fitting an apparatus on board, the temperature is controlled in a lunar vehicle to a heat accumulator, and connecting a radiator having a heat pipe embedded in the inner surface thereof and the above heat accumulator to each other by plural heat conduction paths. CONSTITUTION:During the night of the lunar surface, the temperature of a car body 4 of a lunar vehicle is lowered by radiation cooling, and the thermal energy of an apparatus 1 on board and a heat accumulator 2 where the apparatus is installed is transmitted to a radiator 8 through a thermal switch 6 and heat pipes 5, 7. Accordingly, the temperature of the apparatus 1 on board is kept at a melting point of the heat accumulator 2, so that the temperature of the apparatus 1 on board can be kept at a melting point even during the night. On the other hand, during the daytime of the lunar surface, the temperature of the car body rises, and the apparatus 1 on board is caused to generate heat by itself when the power is applied. Whereupon, the thermal energy is transmitted to the radiator 8 through a heat accumulator 2 as described above. Accordingly, the thermal energy is emitted in the space to prevent the temperature rise of the apparatus 1 on board.

Title: Thin heat dissipation fin and cooling fin employing it
Inventor: NAGASE TOSHIYUKI
IPC: H01L23/36
Filed: 1995-02-10
Abstract: PURPOSE: To reduce the size and thickness of a semiconductor device by specifying the thickness, height and unit length of fins. CONSTITUTION: The thin heat dissipation fin 11 comprises corrugate louver fins 13 bonded to a base plate 12. Following relationship is set among the thickness (t), height H and unit length L of the fin 13; L<4 (H-t), where H=3-15mm. When H is shorter than 2mm, it is very difficult to machine the fin and the heat dissipation characteristics are not enhanced as compared with the case where H=3 mm. When H exceeds 15mm, heat is not transmitted well to the top part of the fin because the fin is relatively thin and the heat dissipation characteristics are deteriorated. The inventive structure can enhance the heat dissipation characteristics while decreasing the labor required for machining the fin body.
