Embodiment Construction

[0015] Such as figure 1 As shown, the present invention includes two phase change heat storage devices 1 , an instrument installation plate 2 , a pre-embedded heat pipe 3 and a loop heat pipe radiator 4 . The instrument mounting plate 2 is a honeycomb panel structure. The honeycomb panel structure includes a high thermal conductivity aluminum alloy skin and a honeycomb core. The thickness of the honeycomb core is 30mm, and the diameter of the honeycomb holes on the honeycomb core is 15mm. The aluminum alloy skin Covering the outer surface of the honeycomb core, the thickness of the aluminum alloy skin is 0.5mm. The middle part of the upper surface of the instrument mounting plate 2 carries the instrument that emits heat. The advantage of using the honeycomb panel as the structure of the instrument mounting plate 2 is that it can maintain a certain structural strength on the premise that the mass of the mounting plate can be effectively reduced. The pre-embedded heat pipe 3 i...

Abstract

The invention discloses a heat collecting storer and relates to the technical field of thermal control. The heat collecting storer comprises two phase-change heat storage devices, an instrument mounting plate, a pre-buried heat tube and a loop heat tube radiator; an instrument which emits heat is carried on the middle part of the upper surface of the instrument mounting plate, the overall pre-buried heat tube is embedded into the instrument mounting plate, and the two ends of the pre-buried heat tube are close to the two opposite side edges of the instrument mounting plate respectively; the two phase-change heat storage devices are fixed on the upper surface of the instrument mounting plate, located under the two ends of the pre-buried heat tube respectively and used for absorbing and storing the heat transferred from the two ends of the pre-buried heat tube; the loop heat tube radiator is fixedly connected to the lower surface of the instrument mounting plate, located under one end of the pre-buried heat tube and used for collecting and dissipating the heat absorbed by the end of the pre-buried heat tube. By the adoption of the heat collecting storer, the heat emitted by the instrument or equipment can be timely and effectively collected and stored, and meanwhile the collected heat can be efficiently transferred to a distant heat sink for dissipation.

Description

technical field [0001] The invention relates to the technical field of heat control, in particular to an instrument for collecting and storing heat through radiation under vacuum conditions. Background technique [0002] During the operation of the spacecraft in orbit, the spacecraft is in a vacuum environment. Since there is no gas for convective heat exchange, the heat exchange between the spacecraft and the external environment is mainly through radiation. At present, there is no solution in the thermal control design of spacecraft for instruments and equipment that can not only collect and store the heat of instruments and equipment in the cabin in a timely and effective manner, but also efficiently transfer the collected heat to long-distance heat sinks when conditions permit. Shen to evacuate. Contents of the invention [0003] The technical problem of the present invention is: to overcome the deficiencies of the prior art, to provide a heat collection storage, whic...
