AI Technical Summary
Technical Problem
Existing thermosiphon radiators face poor working medium flow due to the lack of flow guiding structures, leading to inadequate heat dissipation performance.
Method used
The introduction of flow guide sections with obtuse angles and support members in the heat dissipation fins and chambers to guide the flow of gaseous and liquid working media, enhancing their circulation within the thermosiphon radiator system.
Benefits of technology
Improves the flow efficiency of working media, resulting in enhanced heat dissipation performance by facilitating quicker gas entry into and liquid exit from the gas-liquid chamber, thereby improving the overall radiator's heat dissipation capabilities.

Abstract
A heat dissipation fin, a thermosiphon heat sink, and a multi-dimensional heat dissipation device, relating to the technical field of electronic heat dissipation. The heat dissipation fin includes a housing, an intake port and a drain port installed in the housing, and a gas-liquid chamber installed in the housing. The intake port is used to connect the gas-liquid chamber to an accommodating chamber in a heat dissipation substrate of the thermosiphon heat sink, and the drain port is used to connect the gas-liquid chamber to the accommodating chamber. The intake port has a vertical height greater than that of the drain port. The gas-liquid chamber includes a first guide section used to guide the flow of gas and communicating with the intake port, a second guide section used to guide the flow of liquid and communicating with the drain port, and connecting sections respectively communicating with the first guide section and the second guide section. The angle between the first guide section and the connecting section and the angle between the connecting section and the second guide section are both obtuse angles. The present invention can improve the problem of poor working medium circulation that exists in the prior art, and can improve the heat dissipation performance of the radiator.
