Abstract

The invention discloses an integral and radial multi-leaf-plate metal solar thermotube capable of heating water by using the solar. The thermotube is suitable for a solar water heater, and overcomes weaknesses that the prior photothermal conversion product has low light use efficiency and bad heat-absorbing effect; and the thermotube is characterized in that the invention provides an integral and radial multi-leaf-plate metal thermotube; a light area is increased to obtain more heat energy, a heat-absorbing environment is improved to effectively improve the photothermal conversion efficiency; since the thermotube is formed by a specific die in an one-off extrusion formation technology, the thermotube is in favor of heat conduction and has the characteristics of industrialized production, which provides possibility for industrializing the photothermal conversion and reducing the cost; and the solar water heater manufactured by the thermotube can effectively improve the photothermal conversion efficiency.

Description

Whole, the leafy sheetmetal solar energy of radiation heat pipe

The invention provides a kind of leafy sheetmetal solar energy of integral body, radiation heat pipe that solar water heater uses that is applicable to that adopts solar energy feedwater heating.

The present invention has overcome photo-thermal conversion products in the past, weakness such as the not high and endothermic effect difference of light utilization efficiency.

The purpose of this invention is to provide a kind of integral body, the leafy sheetmetal solar energy of radiation heat pipe, it is under the cooperation of parabolic reflector, not only can there be more area to obtain front lighting and Gao Gao reverberation, and for the chance of more absorption heat energy is provided by the water in managing, can unexpectedly gather in the crops simultaneously the effect of pipe inward flange fuel factor, because this heat pipe is to use special-purpose head, an extrusion molding, its globality helps the conduction of heat, because production technology is simple, also created advantage with reducing cost for its suitability for industrialized production.

The present invention is achieved in that from its cross section and can knows, it be by pipe and some impeller be integral, the integral tube of the special shape of once-forming, and each impeller all is radiation and extends in the pipe outside managing, the inner width of adjacent impeller that divides of pipe can not wait, and every impeller part in pipe necessarily has two faces and a marginal portion; Outside at pipe, comprise that the siphonal lobe plate portion all scribbles the black light-absorbing coating, the two ends of pipe are outside removing part after the impeller, respectively place a clamp nut, then port is processed into chimb, be used for blocking clamp nut, nut is used for being connected with thermal-collecting tube or being connected with extension tube attached, like this when water passes through in managing, just can from the inwall of pipe and in several surface of impeller draw the sunlight heat energy that absorbs from the outer surface of outer impeller and pipe, because impeller all has the marginal portion in each pipe, so the water in the pipe can obtain the edge endothermic effect unexpectedly, use integral body, box or the pipe type solar energy water heater that the leafy sheetmetal solar energy of radiation heat pipe is made can improve the photo-thermal conversion ratio effectively.

Provide embodiments of the invention below in conjunction with accompanying drawing:

Fig. 1 is whole, the leafy sheetmetal solar energy of radiation heat pipe longitudinal profile schematic diagram.

Fig. 2 is the cutaway view of Fig. 1.

Embodiment:

As shown in Figure 1 and Figure 2, can know from its cross section, it is by pipe 1 and the some impeller 2 special form integral tube for one, once-forming, and each impeller 2 all is radiation and extends to outside 1 in the pipe 1 from managing, the width of the adjacent impeller 2 of part can not wait in the pipe 1, the outer part of the outside of pipe 1 and the pipe of impeller 2, all scribble the black light-absorbing coating, the two ends of pipe 1 are after removing part impeller 2, respectively place a clamp nut 3, then port 4 is processed into chimb, is used for blocking clamp nut 3, nut 3 is used for being connected usefulness with thermal-collecting tube or extension tube attached.
