Description

Technical Field

[0001] The utility model belongs to the technical field of solar energy heat pipes, in particular to a new type of glass heat pipe. Background Art

[0002] Solar heat pipes have been used in the field of solar water heaters. They absorb heat through heat pipes, transfer heat to water for heat exchange, and provide hot water for users. The heat pipes in the prior art also have the following defects: the metal glass heat pipe structure in the prior art is to place a metal heat pipe in the inner tube of the vacuum tube, and the inner tube where the metal heat pipe is located is a non-vacuum environment; a heat-absorbing film is plated inside the vacuum tube, and the heat-absorbing film will heat the inner tube of the vacuum tube, thereby heating the medium in the metal inner tube (the medium can be water or other liquid media); however, the vacuum tube is usually a double-layer glass structure, and the light transmittance of the double-layer glass is reduced, and the heat absorption capacity is also reduced. The metal heat pipe is an indirect heat absorber, and the heat absorption speed is slow; in addition, the inner tube of the glass heat pipe is not in a vacuum state, so the heat absorption and heating temperature of the metal heat pipe is limited.

[0003] In summary, the glass heat pipe in the prior art still has the technical problem of slow heating speed. Summary of the invention

[0004] The utility model provides a novel glass heat pipe to achieve the purpose of increasing the heating speed and reducing the cost.

[0005] A new type of glass heat pipe is characterized in that it includes a single-layer glass heat pipe, one end of the glass heat pipe is sealed by melting, and the other end is sealed by melting with a plug, a medium heat pipe is installed on the plug, the medium heat pipe penetrates into the single-layer glass heat pipe, and fins are arranged on the outside of the medium heat pipe, the medium heat pipe is filled with a medium, and the fins are covered with a heat absorption film.

[0006] Furthermore, a telescopic rib is formed on the plug, and a medium heat pipe mounting sleeve is also formed at the outer end of the plug.

[0007] Furthermore, the glass heat pipe is evacuated, and the evacuation position is arranged at the tail of the single-layer glass heat pipe.

[0008] Furthermore, the glass heat pipe is evacuated, and a vacuum nozzle is arranged at the sealing position.

[0009] Furthermore, the vacuum air nozzle is located on the blockage and in a groove formed by the telescopic ribs.

[0010] Beneficial effects of the utility model:

[0011] 1. The heat pipe is single-layer glass, which greatly increases the light transmittance and has a better heat absorption effect. In addition, the raw materials used for single-layer glass are less than those used for double-layer glass in the existing technology, saving production costs;

[0012] 2. The fin coating process is relatively simple, and the number of steps is reduced compared to the glass coating process in the prior art; and the fins are covered with a heat-absorbing film, which directly absorbs heat and transfers it to the metal heat pipe for absorption, thus accelerating heat transfer;

[0013] 3. The metal seal and the glass heat pipe are connected by melting seal to reduce the pipe explosion.

[0014] 4. The glass tube is evacuated. After evacuation, there is no air in the cavity, which has good heat absorption and thermal insulation effects. BRIEF DESCRIPTION OF THE DRAWINGS
