Abstract
The invention discloses a heat collection and conduction device which comprises an inner water tank and a plurality of double-layer glass tube type vacuum tubes, wherein a condensation end cover is arranged at the opening end of each double-layer glass tube type vacuum tube, a sealed metal heat tube is arranged above each condensation end cover, phase-change media is arranged in each metal heat tube, and each metal heat tube is arranged in the inner water tank. The invention has the advantages of reasonable structure, safety, sanitation and good heat conduction effect and avoids tube explosion.
Description
Technical field:
The present invention relates to a kind of heat sink vacuum tube of solar water heater.
Background technology:
At present, the structure of the heat sink vacuum tube of solar water heater is, is made up of inside and outside layer glass pipe, is evacuated between the layer glass pipe, scribbles heat-sink shell at the outer surface of inner layer glass tube.When being installed on the water heater, vacuum tube is connected with the inner water tank of water heater, water is heated in vacuum tube, temperature raises, density diminishes, thus the water that is heated to the upper reaches, cold water flows in the vacuum tube downwards, so water forms convection current in water tank and vacuum tube, relies on the convection current vacuum tube that the water in the water tank is heated.But its shortcoming is, owing to constantly have water to enter in the vacuum tube and water is heated in vacuum tube, makes in the vacuum tube that constantly area has incrustation scale, and is not only unhygienic, and diminishes the Heat-collecting effect of vacuum tube; And when not having water in the vacuum tube, the vacuum tube of this moment often can reach the high temperature of degree more than 200, and be easy to cause vacuum tube bombing if go up water in water tank this moment.
Summary of the invention:
The objective of the invention is provides a kind of rational in infrastructure in order to overcome above deficiency, and safety and sanitation avoid taking place blasted pipe phenomenon, the heat build-up heat-transfer device that heat transfer effect is good.
Purpose of the present invention is achieved through the following technical solutions: a kind of heat build-up heat-transfer device, comprise inner water tank and a plurality of double glazing tubular type vacuum tube, the openend of each double glazing tubular type vacuum tube is provided with the condensation end cap, the top of each condensation end cap is provided with the metal heat pipe of sealing, the inside of each metal heat pipe is provided with phase change medium, and each metal heat pipe places inner water tank.
The present invention compared with prior art has the following advantages:
Because the vacuum tube in this heat build-up heat-transfer device is not communicated with inner water tank, but conduct heat to inner water tank by its metal heat pipe, so not only can not produce incrustation scale in the vacuum tube, nor water on the high temperature can take place and the phenomenon of bombing, owing to use the metal heat pipe for thermal conductivity, the effect that heat is transmitted is relatively good again.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Number in the figure: 1-double glazing tubular type vacuum tube, 2-condensation end cap, 3-metal heat pipe, 4-phase change medium, 5-inner water tank.
The specific embodiment:
In order to deepen the understanding of the present invention, the invention will be further described below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.
Show a kind of embodiment of heat build-up heat-transfer device of the present invention as Fig. 1, comprise inner water tank 5 and a plurality of double glazing tubular type vacuum tube 1, the openend of each double glazing tubular type vacuum tube 1 is provided with condensation end cap 2, the top of each condensation end cap 2 is provided with the metal heat pipe 3 of sealing, the inside of each metal heat pipe 3 is provided with phase change medium 4, and each metal heat pipe 3 places inner water tank 5.
When this solar thermal collector is installed on the solar water heater, double glazing tubular type vacuum tube 1 in this heat build-up heat-transfer device needn't insert water heater inner water tank 5 inside, only the metal heat pipe 3 in the need heat build-up heat-transfer device stretches in the inner water tank 5 and gets final product, the heat build-up heat-transfer device absorbs the air in the sunlight heating inner glass tube, make the inner air tube convection current give metal heat pipe 3 by 2 conduction of condensation end cap with heat, phase change mediums 4 vaporizations in the metal heat pipe 3 and in the condensation of the top of metal heat pipe 3, thus make metal heat pipe 3 constantly heat be conducted to inner water tank 5.The present invention has rational in infrastructure, and safety and sanitation avoid taking place blasted pipe phenomenon, the advantage that heat transfer effect is good.
