Embodiment Construction

[0044] The specific implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0045] The invention relates to the field of phase change heat transfer technology, and discloses an axial channel heat pipe with circumferential grooves and a connection method thereof. A special-shaped groove heat pipe system in which the inner axial groove and the steam channel are connected to each other. Axial channel heat pipe shell is provided with a plurality of circumferential channels arranged in parallel at the port connected to the uniform temperature joint, and the plane where each circumferential channel is located is the same as the axial channel in the axial channel shell. The plane on which it is located is orthogonal, and each circumferential groove is conne...

Abstract

The invention discloses a grooved heat pipe with circumferential grooves and a connection method of the grooved heat pipe. A plurality of axial grooved heat pipe shells with circumferential grooves are combined into a special-shaped grooved heat pipe system through temperature unifying connectors, and in the special-shaped grooved heat pipe system, axial grooves communicate with steam channels. The multiple circumferential grooves which are formed in parallel are formed in the positions of end openings, connected with the temperature unifying connectors, of the axial grooved heat pipe shells,and each circumferential groove is connected with the axial grooves in the axial grooved pipe shells in a through manner. Each temperature unifying connector comprises a main pipe shell and a branchedpipe shell, wherein the main pipe shell and the branched pipe shell are internally provided with axial grooves and circumferential grooves, and the sizes of the axial grooves and the circumferentialgrooves in the main pipe shell and the branched pipe shell are completely consistent with those of the axial grooves and the circumferential grooves of the axial grooved heat pipe shells. The special-shaped grooved heat pipe system in which the axial grooves communicate with the steam channels can take the place of a traditional orthogonal overlapped heat pipe system, overlapping heat resistance between heat pipes is avoided, the heat transfer efficiency and the temperature unifying effect are greatly improved, and the heat pipe arrangement difficulty is lowered.

Description

technical field [0001] The invention relates to a channel heat pipe with a circumferential channel and a connection method thereof, belonging to the technical field of phase change heat transfer. Background technique [0002] Communication satellite technology plays an important role in various fields in various countries in the world, and a large number of space traveling wave tubes are the core components of microwave power amplification on communication satellites. There are a large number of space traveling wave tubes on communication satellites, which consume a lot of power and are scattered on the satellite deck. It is necessary to take appropriate thermal control measures for them to ensure that their on-orbit temperature meets the index requirements. The current common practice is that the space traveling wave tube is arranged inside the satellite deck, and the outer surface of the satellite deck is used as a radiation heat dissipation surface to dissipate the workin...
