Description

Technical Field

[0001] The utility model relates to the technical field of heat conduction pipes, in particular to a heat conduction pipe with a multi-layer composite structure. Background Art

[0002] Heat pipes are suitable for narrow locations such as slender cores and areas that ordinary cooling water cannot reach. They have certain heat transfer performance, and heat from one end can be quickly transferred to the other end. When cooling water is connected at a suitable position, an optimal heat conversion process is achieved, and the cooling effect is good. However, when existing heat pipes are used, they are mostly single metal heat-conducting columns with a single structure, which leads to poor thermal conductivity and affects normal heat dissipation. In order to solve the above problems, we designed a multi-layer composite structure heat pipe. Utility Model Content

[0003] The utility model provides a multi-layer composite structure heat conducting pipe to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A multi-layer composite structure heat-conducting pipe comprises a heat-conducting outer pipe, both ends of the heat-conducting outer pipe are fixedly connected with sealing plates, a heat-conducting inner pipe is arranged inside the heat-conducting outer pipe, the heat-conducting inner pipe penetrates the side walls of two sealing plates, a liquid is arranged inside the heat-conducting outer pipe, the water level of the liquid is higher than that of the heat-conducting inner pipe, a metal plate is fixedly connected to the inner side wall of the heat-conducting outer pipe, a plurality of heat-conducting columns are fixedly connected to the upper side wall of the metal plate, the plurality of heat-conducting columns penetrate the side wall of the heat-conducting outer pipe, a capillary structure is fixedly connected to the outer side wall of the heat-conducting inner pipe located inside the heat-conducting outer pipe, and a metal mesh layer is fixedly connected to the bottom side wall of the metal plate.

[0006] As a further improvement of the technical solution: a graphene layer is fixedly connected to the inner side wall of the heat-conducting outer tube.

[0007] As a further improvement of the technical solution: an anti-corrosion layer is fixedly connected to the outer side wall of the heat-conducting outer tube.

[0008] As a further improvement of the technical solution: the plurality of heat-conducting columns are arranged in a curved shape.

[0009] As a further improvement of the technical solution: the metal mesh layer is formed by weaving together a plurality of identical metal wires.

[0010] As a further improvement of the technical solution: the liquid is ether.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] By placing a low-boiling-point liquid between the outer heat-conducting tube and the inner heat-conducting tube, the liquid completely wraps the inner heat-conducting tube, which can absorb all the heat on the inner heat-conducting tube and then transfer the heat to the outer heat-conducting tube. After absorbing the heat, the liquid boils to generate steam, which then passes through the metal plate and metal mesh layer to improve the thermal conductivity of the steam. This device has dual heat conduction and heat dissipation technology of liquid and steam, which greatly improves the efficiency of heat energy conduction.
