Abstract

A heat pipe network for a satellite or spacecraft is disclosed. The network is constructed from formed and straight heat pipes securely connected together with a highly conductive material, such as Grafoil, serving as an interface gasket. The heat pipe network is interconnected to the subnadir panel and auxiliary panels, and thermally couples the North and South radiator panels. High thermal dissipating units can be mounted to heat pipes on panels attached to the main spacecraft radiator panels. The heat pipes transfer the thermal energy to the radiator panels where it is radiated to space.

Claims

1. A spacecraft having a body, a pair of spaced apart generally parallel radiator panels and a first panel member positioned substantially transversely between said radiator panels, the improvement comprising:

a first plurality of heat pipe members positioned in one of said pair of radiator panels and generally parallel to said first panel member;

a second pair of heat pipe members in thermal communication with and positioned transverse to said first plurality of heat pipe members;

a third plurality of heat pipe members positioned in the other of said pair of radiator panels and generally parallel to said first panel member;

a fourth plurality of heat pipe members in thermal communication with and positioned transverse to said third plurality of heat pipe members; and

a fifth plurality of heat pipe members positioned transversely between said pair of radiator panels and adjacent to said panel member, said fifth plurality of heat pipe members connected by curved heat pipe members to said second and fourth plurality of heat pipe members.

2. The spacecraft as set forth in claim 1 wherein said fifth plurality of heat pipe members are positioned in said transverse first panel member.

3. The spacecraft as set forth in claim 1 further comprising a first plurality of thermal transfer members positioned in said one of said pair of radiator panels and between said first and second plurality of heat pipe members.

4. The spacecraft as set forth in claim 3 wherein said first plurality of thermal transfer members comprise Grafoil members.

5. The spacecraft as set forth in claim 1 further comprising a second plurality of thermal transfer members positioned in said other of said pair of radiator panels and between said third and fourth plurality of heat pipe members.

6. The spacecraft as set forth in claim 5 wherein said second plurality of thermal transfer members comprise Grafoil members.

7. The spacecraft as set forth in claim 1 further comprising a sixth plurality of heat pipe members and a third plurality of thermal transfer members, said sixth plurality of heat pipe members positioned adjacent and substantially parallel to said fifth plurality of heat pipe members, and said third plurality of thermal transfer members being positioned between said fifth and sixth plurality of heat pipe members.

8. The spacecraft as set forth in claim 7 wherein said third plurality of thermal transfer members comprise Grafoil members.

9. The spacecraft as set forth in claim 1 further comprising at least one second panel member positioned transversely between said pair of radiator panels, said second panel member having a seventh plurality of heat pipe members positioned therein.

10. A radiator cooling system for a spacecraft comprising:

a first radiator panel member and a second radiator panel member positioned substantially parallel to each other in said spacecraft;
