Supporting structure for multi-layer heat sinks

Abstract

The invention provides a supporting structure for multi-layer heat sinks with a large dimension and a large span, which effectively solves the problem that the heat sink supporting structure has largeflexibility deformation when the spacing between the inner-most heat sink layer of the multi-layer heat sink structure and the internal wall of a vacuum container is large. The supporting structure adopts the form of adjustable supporting rod and multi-fulcrum, replaces the supporting rods (16) with different heights to realize the height adjustment of the heat sink supporting structure, and meets the different bearing requirements of the heat sink supporting structure by increasing or reducing the number of the fulcrums. A heat sink framework upper supporting wheel (10) arranged on a heat sink framework can freely slide along the axial and radial directions on the guideway (12) of the heat sink supporting structure, thus eliminating the heat sink due to temperature gradients and the expansion amount effects of the heat sink framework in the axial and radial directions.

Description

Multilayer heat sink support structure 【Technical field】 The invention relates to a support structure of a heat sink system, and is especially suitable for a support structure of a multi-layer heat sink. 【Background technique】 When the spacecraft is tested in the ground simulation test system, low-temperature liquid nitrogen heat sinks and liquid helium heat sinks are usually arranged in the container of the simulation system to simulate the cold and dark environment of space, and the low-temperature adsorption technology of the heat sink is used to make the inside of the container. Reach high vacuum (10-4-10-5Pa) or even extremely high vacuum (<10-7Pa) requirements. The installation and support of the heat sink in the container is very important. The heat sink sheet is usually hung on the heat sink frame. The connection mechanism between the heat sink frame and the container is called the heat sink support structure. Under the condition of satisfying the structural str...
