Abstract

The utility model relates to a solar heat collecting element, particularly a solar heat pipe which is a vacuum pipe with a single opening. The utility model comprises an annular vacuum pipe composed of a double-layer transparent glass pipe and a metal heat pipe which is provided with a heat absorbing wing slice and is arranged in the annular vacuum pipe, one end of the vacuum pipe is of closed shape, the other port of the vacuum pipe is provided with a heat insulating plunger, and the surface of the heat absorbing wing slice is coated with absorbing coating. Because the heat pipe of the utility model is completely arranged in a closed-shaped cavity chamber, the light heat conversion absorption rate of the utility model can be enhanced, the vacuum pipe is of single opening shape at the same time, a dismountable structure is formed between the plunger and ports, and the utility model can be conveniently dismounted and repaired for effectively reducing the repair cost. The utility model not only can be used for solar water heaters, but also can be used for solar air conditioners and other solar products.

Description

Solar heat pipe---single radial cut vacuum tube

The utility model relates to a kind of solar collection element, specifically a kind of solar heat---single radial cut vacuum tube.

Chinese patent on April 6th, 94 with notification number is: the document of CN1084955 discloses a kind of technical scheme of removable heat pipe one vacuum pipe solar heat collecting device, it is applied the heat pipe of solar selectively absorbing coating by outer surface, be installed in the all-glass vacuum tube that vacuumizes between the inside and outside glass tube, its vacuum tube is a both ends open, heat insulation with the sealing of removable coupling assembling, make it connect into a complete device and constitute.This technical scheme has increased when vacuumizing because vacuum tube is a both ends open, the connecting and burn the technology difficulty of sealing of exhaust tube and vacuum tube.Simultaneously because the hot junction of heat pipe at its opening part distribute heat, causes the whole thermal efficiency to descend.

The purpose of this utility model is the solar collection element that a kind of heat transfer efficiency height is provided, is easy to process maintenance, long service life.

The purpose of this utility model is to realize like this, it comprises the ring-shaped vacuum pipe that is made of double-layer transparent glass and is fitted to the metal heat pipe of band heat absorption fin in it, one end of described vacuum tube is a closed, an equipped heat insulation plunger on the another port, and the surface of heat absorption fin is provided with absorber coatings.

The dual-side of described heat absorption fin is an arcuation, and its heat absorption fin forms an elastic force pressure to the inwall of vacuum tube, and is provided with support card and air-breathing tail pipe at the blind end of vacuum tube.

The technological progress that the utility model is obtained: because its heat pipe places in the chamber of a closed fully, can improve its thermal absorptivity greatly, and manufacture craft is simple, the cold junction of vacuum tube is the opening shape simultaneously, by heat insulation plug and metal cap it is sealed, thereby dismounting easily and maintenance heat pipe, the damage that has thoroughly solved owing to vacuum tube or heat pipe makes a whole set of solar collection element scrap problems such as the interior pipe that causes with the inboard scaling of all-glass vacuum tube bursts apart, thereby improved the service life of integral solar water heater effectively, this heat collecting element not only can be applicable to solar water heater simultaneously, also can be applicable in the products such as solar airconditioning.

Be that embodiment describes in detail the utility model below with the accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is A-A schematic diagram of Fig. 1.

As shown in Figure 1, vacuum tube 1 constitutes double-decker by the ectonexine clear glass, forms a vacuum layer between the layer glass, and its bulk shape is a column.One end of vacuum tube 1 is a closed, for improving vacuum tube 1 structural stability, has installed support clamp 2 additional between the inside and outside glassy layer of blind end, is provided with at this port simultaneously and vacuumizes the absorption tail pipe.The other end of vacuum tube 1 is an openend, its heat pipe 4 that is provided with the fin 3 that applies absorbed layer is sleeved in the inner layer glass tube, the dual-side of fin 3 is an arcuation, its arcuation limit is supported on the inboard of inner glass tube, as shown in Figure 2, thus fin 3 not only have the heat absorption function also opposite heat tube 4 effect of supporting the location is arranged.An equipped heat insulation plunger 5 on the opening port of vacuum tube 1, the bonding metal cap 6 in the upper surface of heat insulation plunger 5, the outer edge of metal cap 6 is sleeved on the port of vacuum tube 1, install packing ring 7 therebetween additional, heat pipe 4 passes plunger 5 and metal cap 6 and water tank successively and is communicated with, 6 of heat pipe 4 and metal caps are welded as a whole, also can be bonding.In order to make 1 be connected more fastening of metal cap 6 and vacuum tube, also installed clip 8 additional in the outside of metal cap 6.Seal the opening of vacuum tube 1 thus by heat insulation plunger, thereby blocked vacuum tube 1 inner cavity chamber and extraneous cross-ventilation, improved the heat transfer efficiency of heat pipe 1 effectively.During use, sunlight is radiated on the heat absorption fin 3 by two-layer clear glass, light-absorbing coating is converted into heat energy with luminous energy, conduct the phase change medium of giving in the heat pipe 4 through fin 3, phase change medium becomes gas phase towards the cold junction to heat pipe 4, reverts to liquid phase after being cooled, and flows back to the hot junction by deadweight, so repeatedly, the heated medium with cold junction heats.
