Abstract

The invention relates to the field of phase-change heat exchange, and concretely relates to a heated part for multi-angle detection of boiling heat exchange, and an experimental device and an experimental method thereof. The heated part for multi-angle detection of boiling heat transfer comprises a to-be-detected modified surface part and a to-be-detected heated column, the to-be-detected modified surface part is arranged at the top of the to-be-detected heated column, and the to-be-detected modified surface part is mounted on the to-be-detected heated column at a variable angle. According to the heated part for multi-angle detection of boiling heat exchange, and the experimental device and the experimental method thereof, the to-be-detected modified surface part can be fixed in a multi-angle manner relative to the heated part, namely the to-be-detected heated column, so that the angle of a boiling surface is changed, and the technical problem that only upward boiling performance of a horizontal surface can be tested and experimental performance of different placement angles of a modified surface cannot be detected in the prior art is solved.

Description

technical field

[0001] The invention relates to the field of phase change heat, in particular to a heating element for multi-angle detection of boiling heat transfer, an experimental device and an experimental method thereof. Background technique

[0002] At present, as the volume of cutting-edge equipment is getting smaller and smaller, and its power consumption is getting higher and higher, the heat dissipation problem has become a major threat to the service life of the equipment. There have been a large number of theoretical studies, experiments and even applications, which have proved that surface modification has a significant effect on heat dissipation and heat conduction, especially in the field of boiling phase transition, which can change the superheat range of the nucleate boiling region, the overall surface heat transfer coefficient and the critical temperature. heat flux. At present, there is no uniform and standardized test method at home and abroad, and no en...
