Abstract

The invention discloses a convection heat-radiation system for temperature control of electronic equipment close to space vehicle, comprising an electronic equipment pressure maintaining cabin, a liquid storage tank, a pump, an in-cabin finned-pipe heat exchanger, a fan for an in-cabin radiator, an extravehicular finned-pipe heat exchanger, a fan for an extravehicular radiator, a pipeline and circulating fluid, the inlet of the pump is connected with the outlet of the liquid storage tank, the inlet of the liquid storage tank is connected with the outlet of the in-cabin finned-pipe heat exchanger, the inlet of the in-cabin finned-pipe heat exchanger is connected with the outlet of the extravehicular finned-pipe heat exchanger, the inlet of the extravehicular finned-pipe heat exchanger is connected with the outlet of the pump, and the circulating fluid working medium is filled in the pipeline; in the invention, a fluid loop coupling type convection radiator is arranged, waste heat in the electronic equipment is transmitted to the finned-pipe heat exchanger through the fluid loop and is discharged to the ambient atmosphere through the convection radiator driven by the motor; the convection radiator is used in special working environment at bottom part of a stratosphere to carry out heat radiation of high-power electronic equipment, and the structure is compact.

Description

technical field [0001] The invention relates to a heat dissipation system, in particular to a convection heat dissipation system used for temperature control of electronic equipment of an adjacent space vehicle. Background technique [0002] With the rapid development of science and technology and the continuous evolution of the concept of future information-based operations, the strategic value of "near space" (20-100 km altitude), an airspace that humans have seldom set foot in in the past, has gradually attracted attention. At the same time, Due to its advantages such as strong comprehensive capabilities and relatively low cost, near-space vehicles have become a hot spot for research and development by various countries. In addition, a number of flying objects for civil and commercial purposes are also emerging. With the development of airship technology, the application of high-power electronic equipment in stratospheric airships is becoming more and more extensive. In o...

Problems solved by technology

With the development of airship technology, the application of high-power electronic equipment in stratospheric airships is becoming more and more extensive. In order to ensure the normal operation of electronic equipment, corresponding heat dissipation measures must be taken. However, due to the unique environment of temperature and pressure in the Therefore, the cooling measures of stratospheric aircraft are not only different from ground equipment, but also different from flying objects such as satellites outside the atmosphere. Limits the application of high-power electronic equipment on the stratospheric airship

Literature Sang H., James R., Glen C.Powerbudget analysis for high altitude airships[A].AIAA, studied the environmental characteristics at an altitude of 20km, and analyzed the heat dissipation performance of some equipment surfaces with simple structural properties and calculation, but only limited to theoretical calculation and analysis, and has not yet involved the research and development of engineering prototypes, and the difference between the convection cooling system and the quality of the temperature control of the electronic equipment of the adjacent space vehicle
