High-conductance thermal connector
A high conductance thermal link ( 1 ) includes a thermal conductive strap ( 2 ) having pyrolytic graphite layers arranged in stacks ( 5 ) and polyimide film ( 6 ) at least partially covering each stack ( 5 ). Adhesive material is between the pyrolytic graphite layers. The thermal conductive strap ( 2 ) has two opposite ends ( 4 ) and two end fittings ( 3, 3 ′) that house the corresponding ends ( 4 ) of the thermal conductive strap ( 2 ). An adhesive material is in the ends ( 4 ) of the thermal conductive strap ( 2 ) between the pyrolytic graphite layers and between the stacks ( 5 ) of pyrolytic graphite layers. At least one of the ends ( 4 ) of the thermal conductive strap ( 2 ) has a geometry including protrusions ( 7 ) separated by intermediate gaps ( 8 ).
1. A high conductance thermal link comprising:
a thermal conductive strap comprising pyrolytic graphite layers arranged in stacks and polyimide film at least partially covering each stack, with adhesive material between the pyrolytic graphite layers, the thermal conductive strap having two opposite ends, and
two end fittings that house the corresponding ends of the thermal conductive strap, at least one of the two opposite ends of the thermal conductive strap having a geometry comprising a plurality of protrusions separated by intermediate gaps,
an adhesive material in the two opposite ends of the thermal conductive strap between the pyrolytic graphite layers and between the stacks of pyrolytic graphite layers, the stacks of pyrolytic graphite layers being covered by polyimide film, and the two end fittings comprise two symmetrical halves attached by connector elements.
2. The high conductance thermal link according to claim 1 , wherein the layers of pyrolytic graphite are arranged as sheets.
3. The high conductance thermal link according to claim 1 , wherein the two end fittings are made of metal or made of organic material.
4. The high conductance thermal link according to claim 1 , wherein the adhesive material is only in the two opposite ends of the thermal conductive strap.
