A coupling heat transfer assembly of truss heat pipe and loop heat pipe for spacecraft

Abstract

A aerospace heating tube and circular heat pipe coupling component, including heat exchanger case (2), heat exchanger core, packaging end (1), conversion connector (4) and end cover (3); replacement; replacement The thermal shell (2) and the ring thermal pipe condensation pipe road coupled through the coagulation pipeline of the ring, and the heat exchanger core and the heat exchanger shell (2) are coupled through the Zhouxiang Wing Tablet (11) One end of the thermal core is connected to the truss heat pipe case (5) through the connection of the connector (4), and the other end of the heat exchanger core is seal with the packaging end (1); , Inner wing tablet with the outer wings of the heaters core (11) insert coupling, coat thermal silicon grease at the coupling site, and use end cover (3) packaging at both ends (2) ; The heat exchanger core, the rotor connector (4), the truss thermal tube shell (5), and the packaging end (1) are seal connected to form a sealing system.

Description

technical field [0001] The invention belongs to the technical field of vapor-liquid phase change heat transfer for spacecraft, and relates to a heat transfer component for coupling a truss heat pipe and a loop heat pipe. Background technique [0002] With the development of spacecraft towards a comprehensive and integrated system, the increase in the number of spacecraft payloads and the multi-channel and multi-angle development of a single load have increasingly put forward higher demands on power consumption resources. Due to the limitation of orbital power generation, it is impossible to meet the increasing demand for power consumption resources without limit. In this case, the concept of spacecraft thermal management highlights its advantages. An important feature of the spacecraft thermal management concept is to conduct unified allocation and comprehensive utilization of the spacecraft's thermal environment and subsystem thermal behavior from a system perspective, so a...

Problems solved by technology

This leads to, on the one hand, due to the long pipeline required, the flow resistance that the loop heat pipe capillary pump needs to overcome is very large, which will reduce its maximum heat transfer power; Welding coupling cannot be realized between the condensing pipes and the composite panel, and the heat conduction resistance between the condensing pipe and the composite panel is very large, which reduces the heat consumption efficiency of the refrigerator
