Embodiment Construction

[0036] Carry out further detailed description below in conjunction with accompanying drawing:

[0037] figure 1 A schematic structural diagram of a temperature control system for a lunar rover is given, including a self-circulating fluid circuit, a phase-change material energy storage device 6 and a solar-driven evaporation and condensation self-reflux heat exchange device 7 . Among them, the self-circulating fluid circuit includes a liquid storage tank 2, a capillary temperature-controlled flow valve 3, a fluid pipeline 4, a porous core evaporator 5, and a gas pipeline 9. During the moon and day, the solar energy drives the evaporation and condensation self-reflux heat exchange device 7 to absorb solar radiation heat outside the lunar rover, and transfer heat to the phase change material through the tree-like branch fin structure 14 of the condensation area 15 immersed in the phase change material, The phase change material absorbs heat and undergoes phase change, and stores...

Abstract

The invention discloses a lunar vehicle temperature control system. The lunar vehicle temperature control system comprises a self-circulation fluid circuit, a phase-changing material energy storage device and a solar driving evaporation condensation self-reflux heat exchanging device, wherein the self-circulation fluid circuit comprises a liquid storage tank, a liquid pipeline, a porous core evaporator, a gas pipeline and a capillary pipe temperature control flow valve which is connected to the liquid pipeline; the phase-changing material energy storage device comprises an energy storage box and a phase-changing material which is arranged in the energy storage box, and the porous core evaporator is arranged in the energy storage box; the solar driving evaporation condensation self-reflux heat exchanging device comprises a vacuum pipe and a phase-changing heat conduction medium in the vacuum pipe, the vacuum pipe comprises a heat absorption evaporation area and a heat release condensation area, the heat release condensation area is arranged in the phase-changing material of the energy storage box, and a tree-shaped branch rib structure is arranged in the heat release condensation area. By adopting the temperature control system, the heat balance of a lunar vehicle body is maintained, the high-efficiency transmission of the heat can be realized without power supply, the heat supply safety and long-term running stability of the lunar vehicle can be greatly improved at moonlit night, and a reliable temperature control effect can be provided for the lunar vehicle.

Description

technical field [0001] The invention relates to a lunar rover temperature control system, in particular to a lunar rover temperature control system based on a lunar surface g / 6 gravity self-circulating fluid circuit and phase change materials. Background technique [0002] As an important part of the lunar rover, the temperature control system keeps the temperature levels of the astronauts, power supply, integrated electronics, mobile, navigation, measurement and control and other sub-systems in the lunar rover within the specified range by controlling the heat exchange process inside and outside the rover. In order to ensure that the lunar rover can carry out lunar exploration activities safely and efficiently. [0003] The day and night time of the moon is about 14 days each, and the temperature difference between day and night is large. The temperature during the day is as high as 150°C, and it can drop to -180°C at night. Traditional methods such as cooling plates can e...
