Abstract

The utility model relates to a solar energy heat pipe light-focusing heat collector. The utility model comprises a heat pipe (4), reflecting plates which are arranged on the side part and the lower part of the heat pipe, etc. A transparent cover plate (3) is arranged on the upper part of the heat pipe, a frame (1) is arranged around the heat pipe, and a bottom plate (6) is arranged on the lower part of the heat pipe. A heat-resistance sealing member is arranged between the transparent cover plate (3) and the frame (1). A heat-insulating material layer (2) is arranged among the frame (1), the bottom plate (6) and the reflecting plates (5). The cross sections of the reflecting plates (5) respectively form a circle shape that two symmetrical involutes (5a) are externally connected with parabolas (5b), and have a layer structure of an organic protective film layer, a ceramic protective film layer, a high-purity aluminum film layer and a pure aluminum plate backing material layer from top to bottom.

Description

The solar heat pipe concentrating collector

Technical field

It is thermal-arrest, the heat transfer unit (HTU) of thermal source with the sunshine that the utility model relates to a kind of, is suitable for the heating in dwelling house and other place especially, the application of life aspects such as the hot water supply of resident family.

Background technology

The solar thermal collector pattern is various, and many usefulness of dwelling house and other place heating are flat, and the base plate of thermal-collecting tube bottom is smooth, and areflexia light focuses on heat effect, or adopts the corrugation shape of half-arc groove, and reflection heat build-up effect is undesirable; Flat pipe upper exposed area is big, and the heat-energy losses of the infrared radiation after the pipe heat absorption is also big, and the thermal efficiency is on the low side.That civilian solar water heater is the most general is the vacuum tubular glass solar collector, also exist above-mentioned flat similar problem, and the reflecting plate of vacuum tube bottom makes of single-layer metal, do not have the insulation material liner, reflecting effect is bad, and heat conduction and radiation loss are big.

Summary of the invention

The utility model is designed a kind of efficient high-efficiency solar heat pipe heat collector high, that heat is conducted, radiation loss is little that reflects heat build-up at the above-mentioned deficiency of prior art.

Above-mentioned purpose can realize by following measure: it includes heat pipe; the reflecting plate of this pipe below etc.; there is transparent cover plate the top, has frame, below that base plate is arranged all around; the temperature resistant encapsulation part is arranged between transparent cover plate and the frame; between base plate and the reflecting plate adiabator layer is arranged; the cross section of reflecting plate is the shape of the external parabola of involute (face) (face) of round two symmetries, and is the layer structure of organic protective film layer, ceramic protective film, rafifinal rete, pure aluminum plate substrate layer from top to bottom.

The purpose of this utility model can also be come perfect by following measure: transparent cover plate is for double-deck, and the centre is filled with inert gases such as krypton gas.

Description of drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is the drawing in side sectional elevation of Fig. 1.

Fig. 3 is the enlarged drawing of a thermal-arrest unit among Fig. 2.

The specific embodiment

The utility model is below in conjunction with embodiment and with reference to accompanying drawing, be described in further detail: heat pipe 4 outsides are the single-glass pipe, vacuum in the pipe, in be the finned copper pipe that is filled with heat-conducting medium, the surface scribbles black sun coating, characteristic is this reflecting plate 5 of managing 4 belows, the cross section of its each heat absorbing units is to be that circular endothermic tube is that the external parabola of involute (face) 5a (face) 5b of two symmetries of basic circle combines with the cross section, very narrow because of cuing open " face ", can make " line " treats, this can see clearly from Fig. 3, and the upside of heat absorption circle 4 is other to be parabola (face) 5b, and downside is taken up the below and is involute (face) 5a, according to light optically focused principle, in daylighting half-angle scope, the light of incident all can be pooled on the focal line, and just in time is the installation place of endothermic tube 4 on this focal line; According to the involute characteristic, the normal of involute any point is all tangent with basic circle 4 again, and therefore, the light that is incident on the reflecting surface of involute (face) all reflexes on the endothermic tube 4.As seen the reflecting plate 5 that combines with involute of parabola is the version optimal, that Heat-collecting effect is best.Again this reflecting plate 5 is made layer structure; orlop is made the base material punch forming by fine aluminium, coats the rafifinal rete earlier, coats ceramic protective film again, coats the good organic protective film layer of light transmission at last; to improve reflecting properties and corrosion-resistant, dust protection, low decay property, increase the service life.The transparent cover plate 3 of heat pipe 4 tops should be double-deck, is filled with krypton or other inert gas in it, more effectively improves heat-insulating property.Be adiabator layer between reflecting plate 5 and base plate 6 and the frame 1, expandable plastic is filled, or with the more hydrocarbon filling of compliance with environmental protection requirements.Temperature resistant encapsulation part between double glazing cover plate 3 and the frame 1 can adopt the heat resistant rubber seal, and both the krypton gas in the Sealed sandwich also can reduce the loss of heat.Frame 1 is seen each member in it with base plate 6 carryings.Each single concentrating collector can become a big domestic-heating system or hot water supply system through mozzle 7 serial or parallel connections with other concentrating collector.Also can be single be connected, add upper bracket and make small-sized pot-type boiler with water tank.Usage range also can be expanded with drawing inferences about other cases from one instance.

The utility model compared to existing technology, it is good to have an endothermic effect, few advantage of dispelling the heat is one of desirable version in temperature (100-200 ℃) heat utilization in the solar energy.
