Abstract

The invention provides a condenser and a low-temperature loop heat pipe, and relates to the technical field of spacecraft thermal control. The condenser comprises a main body component and at least one condensation path; a space occupied by the main body component is limited by a first surface; each condensation path includes a first port and a second port located at the both ends of the condensation path, and further comprises a second surface extending between the first port and the second port, wherein the second surface is entirely located within the space defined by the first surface andoccupied by the main body component. According to the condenser provided by the invention, the condensation path is equivalently arranged in the main body component, so that compared with a traditional condenser, the heat transfer area can be increased while the superficial area is reduced in an effective volume, and the heat exchange efficiency and stability of the condenser are greatly improved.

Description

technical field [0001] The present application relates to the technical field of spacecraft thermal control, in particular to a condenser and a low-temperature loop heat pipe. Background technique [0002] In space detection and earth observation technology, infrared detection technology is an important high-tech. Infrared detection systems generally include infrared optical systems, infrared detectors, information processing equipment, display and control devices, and scanning mechanisms. Among them, the infrared detector converts the accumulated radiant energy into an electrical signal, which is sent to the display and control device after amplification, collection and processing. For the photon detector with the highest sensitivity, it generally needs to work at a low temperature below 100K. [0003] In order to meet the needs of high-efficiency heat transfer technology in deep low-temperature regions, in 2000, foreign researchers developed a new type of loop heat pipe,...
