Embodiment Construction

[0045] Such as figure 1 As shown, the present invention is an aluminum vertical heat sink device with relatively high temperature distribution uniformity applied to micro-satellite space environment simulation tests. The heat sink device consists of a finned tube array surface (1), a metal corrugated soft Tube (2), multi-layer insulation material (3) and temperature acquisition system (4). The position connection relationship between them is: eight 460mm x 1160mm finned tube array surfaces (1) form the sides of an octagonal prism; two 1120mm x 1200mm finned tube array surfaces (1) are the top of the heat sink device surface and bottom surface; metal corrugated hose (2) connects each surface to make the inner cavity of the whole heat sink device integrated; the thermistor in the temperature acquisition system (4) is attached to the outer surface of the heat sink device; multi-layer heat insulation material ( 3) is coated on the outermost part of the device.

Abstract

The invention discloses an aluminum-made vertical heat sink device with high temperature distribution uniformity. The heat sink device consists of fin tube array sides, a metal corrugated soft pipe, a plurality of thermal insulating material layers and a temperature acquisition system, wherein an eight-prism-shaped side surface is formed by eight fin tube array sides being 460mm*1160mm; two fin tube array sides being 1120mm*1200mm are respectively used as the top surface and the bottom surface of the heat sink device; the metal corrugated soft pipe is connected with the surfaces so as to integrate an inner cavity of the whole heat sink device; thermistors in the temperature acquisition system are adhered to the outer surface of the heat sink device; and the plurality of thermal insulating material layers are wrapped at the outermost surface of the device. The aluminum-made vertical heat sink device has the advantages of good temperature distribution uniformity, good cooling effect, rapid cooling speed, small size, convenience in operation and maintenance, and the like, and has a good practical value and an application prospect in the field of space technologies.

Description

technical field [0001] The invention relates to an aluminum vertical heat sink device with relatively high temperature distribution uniformity, which is applied to micro-satellite space environment simulation tests and belongs to the field of aerospace technology. Background technique [0002] The spacecraft works in a complex space environment for a long time, and the harsh environment such as solar radiation, vacuum cold darkness and electromagnetic radiation seriously threatens the safety of the spacecraft and the completion of the mission. Therefore, when developing a new type of spacecraft, it is necessary to conduct sufficient environmental simulation tests on the ground, through the test to find hidden dangers, improve the design, and avoid early failure, thereby improving the reliability of the spacecraft. The most important thing is to simulate the space thermal environment conditions on the ground to carry out the vacuum thermal test, and the heat sink device is on...
