Abstract
Description
Technical Field
[0001] This invention relates to the installation design of high-power devices, and particularly to a method for installing high-power devices with a single fixed point in space. Background Technology
[0002] The single-fixed-point high-power device inside the satellite is installed on the inner side of the mounting surface of the single unit and dissipates heat through the mounting surface. However, due to the low rigidity of the single-fixed-point high-power device itself, under the traditional fixing method, when fixing the single-fixed-point high-power device, the contact heat conduction is good on the fixed side of the single-fixed-point high-power device, while the contact heat conduction on the non-fixed side is worse than that on the fixed side. As a result, the heat generated by the single-fixed-point high-power device is concentrated on the non-fixed side, resulting in insufficient heat dissipation of the single-fixed-point high-power device.
[0003] To address existing problems, this invention aims to provide an installation method for a single-fixed-point high-power device for space applications. This installation method is an innovation for single-fixed-point high-power device installation and can provide a new solution for the installation of single-fixed-point high-power devices for spacecraft. Summary of the Invention
[0004] To address the problem of insufficient heat dissipation in high-power devices with single fixed points, this invention provides an installation method for high-power devices with single fixed points in space, characterized by comprising: an installation structure 1, a thermally conductive pad 2, a high-power device with a single fixed point 3, a rubber protective pad 4, and a spring pressure plate 5; The thermal pad 2, the single-fixed-point high-power device 3, and the spring pressure plate 5 are fixed to the mounting structure 1 from bottom to top using a set of standard fasteners. The rubber protective pad 4 is installed on the non-fixed side of the single fixed point high-power device 3, and is positioned between the single fixed point high-power device 3 and the spring pressure plate 5. The rubber protective pad 4 has a certain plastic deformation capacity, which transmits the pressure of the spring pressure plate 5 on the non-fixed side of the single fixed point high-power device 3; The spring pressure plate 5, through its own elastic deformation, applies a certain pressure to the non-fixed side of the single fixed-point high-power device 3 via the rubber protective pad 4.
[0005] The technical solution provided by this invention has the characteristics of small space restriction, good contact of device mounting surface and strong heat dissipation of device, and is particularly suitable for the installation application of high-power devices with limited installation space, single fixed point and high power devices in spacecraft.
[0006] The advantages of this invention compared to the prior art are: (1) The elastic deformation of the spring pressure plate increases the pressure on the mounting structure in the non-fixed side of the high-power device with a single fixed point in the heating area, resulting in good contact between the device mounting surface and the heat dissipation performance of the high-power device with a single fixed point. (2) Single fixed-point high-power devices are installed in this way, which has the characteristics of small space occupation and no space restriction. Attached Figure Description
[0007] Figure 1 This is a schematic diagram of a high-power device installed at a single fixed point. Figure 2 This is a design drawing for the installation of a high-power device at a single fixed point (without internal forces). Detailed Implementation
[0008] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0009] Please refer to Figure 1 The present invention provides a method for installing a single-fixed-point high-power device for space applications, comprising: an installation structure 1, a thermally conductive pad 2, a single-fixed-point high-power device 3, a rubber protective pad 4, and a spring pressure plate 5. The thermally conductive pad 2, the single-fixed-point high-power device 3, and the spring pressure plate 5 are sequentially fixed to the installation structure 1 from bottom to top using a set of standard fasteners; the rubber protective pad 4 is installed on the non-fixed side of the single-fixed-point high-power device 3, positioned between the single-fixed-point high-power device 3 and the spring pressure plate 5. The rubber protective pad 4 has a certain plastic deformation capacity, which transmits the pressure of the spring pressure plate 5 on the non-fixed side of the single fixed point high-power device 3; The spring pressure plate 5, through its own elastic deformation, applies a certain pressure to the non-fixed side of the single fixed-point high-power device 3 via the rubber protective pad 4.
[0010] The single-fixed-point high-power device 3 has only one fixed point, which is located on one side of the single-fixed-point high-power device (fixed side), while the heat-generating area of the single-fixed-point high-power device is concentrated on the other side (non-fixed side).
[0011] The rubber protective pad 4 is located on the non-fixed side of the single fixed point high-power device 3, and is made of 1.5mm thick aviation rubber sheet of grade 1150.
[0012] The spring pressure plate 5 is made of 1Cr18Ni9Ti stainless steel plate with a thickness of 1mm. Under no internal force, on the non-fixed side of the single-fixed-point high-power device 3, the distance δ between the spring pressure plate 5 and the single-fixed-point high-power device 3 is controlled between 0.1-0.3mm.
[0013] This invention provides a method for installing a single-fixed-point high-power device in a space-constrained environment, characterized by minimal space requirements, good contact between the device mounting surface and the device, and strong heat dissipation. The elastic deformation of the spring pressure plate increases the pressure on the mounting structure in the non-fixed heat-generating area of the single-fixed-point high-power device, ensuring good contact between the device mounting surface and improving the heat dissipation performance. This method of installing single-fixed-point high-power devices occupies little space and is not limited by space constraints, providing a new approach to the installation design of such devices.
[0014] The installation method for a single-fixed-point high-power device for space applications provided by this invention has been tested under various temperature conditions. The single-fixed-point high-power device exhibits significant cooling effect, demonstrating good heat dissipation performance and proving its reliability and safety.
[0015] The technical solution provided by this invention has the characteristics of small space restriction, good contact of device mounting surface and strong heat dissipation of device, and is particularly suitable for the installation application of high-power devices with limited installation space, single fixed point and high power devices in spacecraft.
