Description
Technical Field
The invention relates to the field of satellite parts, in particular to a precision maintaining and fixing device of a multidimensional bending channel heat pipe for a satellite.
Background
The satellite heat pipes are important components of a satellite thermal control assembly, are widely distributed in a satellite structure and are limited by heat transfer conditions and layout constraint conditions, and generally have the characteristics of complex structure (mostly a spatial slender bending rod structure), high installation precision requirement (connected with a satellite structure through a threaded positioning hole) and different shapes.
Based on the structural characteristics, the satellite heat pipe needs to pass through complicated process flow, storage and transportation processes from production to assembly. During the period, the finished heat pipe is easy to cause secondary deformation if no clamp is fixed, and the installation precision is affected. On the other hand, because the satellite heat pipes have different space sizes and fixed positions, a special clamp is designed for each heat pipe, which wastes resources and occupies space.
Typical heat pipes for satellites are generally finned tube structures. The heat pipe can be fixed by using the mounting hole of the heat pipe or pressing the pressing block to press the fin. However, most of the existing satellite heat pipes adopt a simple bundling or foam filler supporting mode in the storage and transfer processes, and the existing satellite heat pipes do not have the function of maintaining the shape, position, size and precision of the heat pipes.
Therefore, the universality and the clamping and positioning accuracy need to be considered, and the precision maintaining and fixing device of the multidimensional bending channel heat pipe for the satellite is designed so as to realize the precise portable fixing of the satellite heat pipe.
