Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat pipes, in particular to a heat pipe with a 3D MESH composite sintered structure. Background Art
[0002] The inner wall of the existing heat pipe is provided with a capillary structure (such as Figure 2 ), the capillary structure can be a woven mesh with capillary action, etc., and the capillary action of the capillary structure can facilitate the transmission of the working fluid in the heat pipe.
[0003] The existing publication number CN209820235U discloses an ultra-thin liquid-vapor two-phase flow heat pipe structure; the sintered metal powder on the inner wall of the traditional heat pipe is a sintered metal layer attached to the inner wall of the heat pipe. Now the traditional sintered metal structure is changed, and the sintered metal powder is only retained on a part of the inner wall. Since the inner wall has one less layer of powder, compared with the traditional structure process, under the same outer diameter, this new structure can achieve a thinner effect. However, due to the single capillary structure, the heat pipe Qmax has room for further improvement. For this reason, we propose a heat pipe with a 3D MESH composite sintered structure.
