Embodiment Construction

[0010] combine figure 1 Describe this embodiment, a heat insulation pad suitable for thermal control of a space camera, the heat insulation pad includes a polyimide ring 1, a multilayer heat insulation material gasket 2, a heat insulation pad fixing point 3 and a multilayer fixing point 4. The polyimide ring 1 of the thermal insulation pad is in direct contact with the equipment on both sides, and the multi-layer thermal insulation material gasket 2 in the center is not in contact with the equipment; the multi-layer thermal insulation material gasket 2 passes through the multi-layer The fixed point 4 is fixed with the polyimide ring 1 along the circumferential direction with screws, and the polyimide ring 1 is fixed with the equipment on both sides along the circumferential direction with bolts through the fixed point 3 of the heat insulation pad.

[0011] The heat insulation pad described in this embodiment isolates the conductive heat exchange between the equipment on both s...

Abstract

A heat-insulation cushion applicable to heat control of a space camera relates to the technical field of heat control of space cameras and solves the problem that a fine heat-insulation effect and weight reduction of an existing heat-insulation cushion for heat control of a space camera cannot be realized simultaneously. A plurality of heat-insulation cushion sheets of the heat-insulation cushion are circumferentially clamped among polyimide rings and are fixed by screws via a plurality of layers of fixing points, and the polyimide rings are connected with corresponding equipment by bolts via heat-insulation cushion fixing points. The weight of a heat control system of the space camera can be remarkably lightened, resources of the space camera can be saved, design requirements can be effectively met, and the heat-insulation cushion is convenient and reliable in use.

Description

technical field [0001] The invention relates to the technical field of thermal control of space cameras, in particular to a thermal insulation pad suitable for thermal control of space cameras. Background technique [0002] In the thermal control of space cameras, in order to reduce the impact of the satellite platform or other equipment connected to the camera on the thermal environment and temperature level of the camera body, it is often necessary to add a heat insulation pad at the connection part to isolate the heat exchange between the camera body and peripheral equipment as much as possible. . [0003] The space camera operates in a high-vacuum environment, and the heat transfer between devices depends on contact conduction and space radiation, so the heat insulation pad used at the connection between the camera body and peripheral equipment needs to have good insulation conduction and radiation heat transfer capabilities; in addition In addition, because the heat in...
