Abstract

The utility model relates to a full glass double vacuum solar energy superconduct heat collection pipe comprising a glass inner pipe and an external pipe that are bushed in a same axle, which is characterized in that: a condensation section that extends out of the external pipe for certain length is positioned in the inner pipe; a heat conduction medium is filled in the inner pipe; the upper opening of the external pipe is sealed on the external wall of the glass inner pipe via melting; the interlayer between the inner and external pipes as well as the inside of the inner pipe are pumped into vacuum; a metallic wire net is positioned in the inner pipe; the inner wall of the inner pipe is configured with crude surface and distributed with a plurality of axial groove, which enlarges the heat transmission area of the heat collection pipe and greatly enhances the heat efficiency.

Description

The two vacuum solar superconducting heat collection pipes of full glass

(technical field)

The utility model relates to the two vacuum solar superconducting heat collection pipes of a kind of full glass, belongs to solar energy heat collector.

(background technology)

At present, the many dual-layer vacuum glass pipes of making by the mutual socket of inside and outside two-layer U type glass tube of solar energy glass thermal-collecting tube, the interior water flowing case of the pipe of double-layer glass tube is a medium with water, the interior water of water and case constantly circulates in the pipe, makes water temperature rising in the water tank.Its shortcoming be insolation in summer or winter temperature low excessively the time, cause the glass tube explosion easily, and water at high temperature easily makes tube wall incrustation, influence heat-transfer effect and service life.Thereby the glass heat collection tube of a kind of upper end sealing by fusing is arranged at present, and the performance of packing in the pipe is better than the heat-conducting medium of water, and medium does not communicate with water tank, but has circulation of one's own in thermal-collecting tube, thereby overcomes the shortcoming of the easy explosion of glass tube.But in actual the use, its heat transfer efficiency is also treated further raising.

(summary of the invention)

The purpose of this utility model provides the two vacuum solar superconducting heat collection pipes of a kind of full glass, to improve the heat transfer efficiency of thermal-collecting tube.

The utility model thermal-collecting tube contains the U type glass outer tube and the U type glass inner tube of mutual socket, glass inner tube has one section condensation segment that exceeds outer tube suitable length and upper end sealing by fusing, in the tube chamber of interior pipe heat-conducting medium is housed, the sealing by fusing suitable for reading of outer tube is on the outer wall of glass inner tube, vacuumize respectively in the tube chamber of interlayer between the inner and outer pipe and interior pipe, the inwall of interior pipe is crude surface, and is distributed with several axial grooves, and woven wire also is housed in the pipe.

Not only the be situated between glass tube of having determined of this thermal-collecting tube is explosive, the problem of easy fouling, prolonged service life, and interior pipe vacuumizes, internal face is processed into hair side, sets up groove and installs woven wire additional, these schemes all can be quickened heat-conducting medium gasification and diabatic process, make the long-pending increase of sensor hot side, and the thermal efficiency improves greatly.

(description of drawings)

Fig. 1 is the structural representation of the utility model thermal-collecting tube.

Fig. 2 is an A-A cross section structure schematic diagram.

As shown in Figure 1, glass outer tube 2 is placed in outside the glass inner tube 1, and its 6 sealings by fusing suitable for reading are on the outer wall of interior pipe 1, and the outer wall of interior pipe 1 scribbles heat absorption and films 7, heat-conducting medium is housed in the tube chamber 4 and vacuumizes.The upper end of interior pipe 1 exceeds outer tube 2 certain-lengths, its upper end sealing by fusing, and this is a condensation segment.Vacuumize in the interlayer 3 between the inner and outer pipe; Between interior pipe 1 bottom and the outer tube 2 reed support 5 is housed, axially consistent to guarantee interior 1 with outer tube 2.

Fig. 2 represents that the inwall of glass inner tube 1 is a hair side, and makes a plurality of groove 1-1, and stainless steel cloth 8 is housed in the pipe.

The condensation segment of this heat pipe is inserted in the sealing-in mouth of water tank, by continuous gasification and the condensation of heat-conducting medium in glass inner tube 1, the medium self-loopa of formation with the water of the thermal energy transfer feed-tank of the sun, reaches the purpose that adds hot water simultaneously.
