Abstract
The utility model discloses a semi-enclosed anti-scale evacuated solar collector tube which comprises an inner tube and a cover glass tube which is integrated with the inner tube into a whole by fusion. The solar collector tube also comprises a heat exchange section, wherein the heat exchange section is formed in such a manner that the upper end of the inner tube extends in a certain length and the tail end is incompletely closed, or a cup-shaped heat conductive object with a pore on the top is additionally sleeved; and the pore formed on the top of the heat exchange section is used for balancing the internal pressure of the inner tube and a header or a water tank. The heating medium in the inner tube circulates in the inner tube in a thermo-siphon manner and exchanges heat with a medium in the header or the water tank in the heat exchange section, the pore on the heat exchange section is a medium pressure balancing port, the volume of the heating medium changes due to the temperature transformation, and then the heating medium flows in or out through the pore, so that the internal pressure of the medium of the inner tube and the internal pressure of the medium of the header or the water tank are adjusted to be balanced, the mass of medium flowing in and out of the pore is very small, the medium in the inner tube and the medium in the header or the water tank are relatively closed, so that the generation of scales is reduced, the instantaneous heating efficiency of the solar collector tube is ensured not to decrease, and the problem of scaling of the conventional evacuated solar collector tube is solved.
Description
Technical field
The utility model relates to a kind of solar thermal collector parts, more particularly, relates to a kind of semiclosed antiscale vacuum solar heat-collecting pipe.
Background technology
As shown in Figure 1; Traditional vacuum solar heat-collecting pipe is the core component by solar vacuum-tube water heater; Traditional vacuum heat collection pipe 29 is by interior pipe 30, merges all-in-one-piece cover glass tubes 31 with interior pipe 30 and constitute; Be provided with vacuum interlayer 32 between interior pipe 30 and the cover glass tube, scribble solar selectively absorbing coating on interior pipe 30 outer walls, interior pipe 30 bottoms are provided with the bracing frame 33 that is positioned at vacuum interlayer 32.When this all-glass vacuum thermal-collecting tube is installed on the solar vacuum-tube water heater; The end that vacuum heat collection pipe is had an opening inserts in the water tank and is fixedly connected with water tank through sealing ring; The heat-insulation layer that vacuum heat collection pipe passes between water tank and the shell stretches out outside the shell; Utilize thermosiphon principle that the water in the water tank is heated, heat exchange is carried out in the water in the water tank and the water convection current of interior pipe 30, and the inwall at interior pipe 30 forms incrustation scale easily.
The utility model content
The purpose of the utility model is to overcome above-mentioned defective of the prior art; Medium and the interior medium relative closure of water tank in a kind of interior pipe are provided; Reducing incrustation scale generates; Can keep solar energy heat collection pipe is that the thermal efficiency does not descend, and solves the semiclosed antiscale vacuum solar heat-collecting pipe of the incrusted problem of present vacuum pipe solar.
For realizing above-mentioned purpose; The technical scheme that the utility model provides is following: a kind of semiclosed antiscale vacuum solar heat-collecting pipe is provided; Comprise interior pipe, merge the all-in-one-piece cover glass tube with interior pipe; Extend the heat exchanging segment that the certain-length end not exclusively seals or the cup-shaped heat conduction object of pore is opened at other socket top and form on managing in also comprising, the top of heat exchanging segment offers the aperture with pipe in the balance and header or water tank internal pressure.
The beneficial effect of the described semiclosed antiscale vacuum solar heat-collecting pipe of the utility model is: the heat exchanging segment that the cup-shaped heat conduction object of opening pore by terminal not exclusively sealing of extension certain-length on the interior pipe or other socket top through structure forms, the top of heat exchanging segment offers with the aperture of the interior pipe of balance with the water tank internal pressure.Thereby manage interior heat medium portion's thermosyphon circulation within it in making, in heat exchanging segment and header or the heat exchange of water tank medium, the aperture on the heat exchanging segment is the pressure medium balance port; The heat medium temperature conversion causes Volume Changes; Flow out or inflow through this aperture, pipe internal pressure and header or water tank medium reach balance in reducing, and aperture turnover medium amount is very little; Medium and header or water tank medium relative closure in the interior pipe; Reduce incrustation scale and generate, can keep solar energy heat collection pipe is that the thermal efficiency does not descend, and has solved the incrusted problem of present vacuum pipe solar.
Below in conjunction with accompanying drawing and embodiment the described semiclosed antiscale vacuum solar heat-collecting pipe of the utility model is described further.

The specific embodiment
Below be the preferred example of the said semiclosed antiscale vacuum solar heat-collecting pipe of the utility model, therefore do not limit the protection domain of the utility model.
Embodiment one; With reference to Fig. 2, Fig. 3; A kind of semiclosed antiscale vacuum solar heat-collecting pipe is provided, pipe 1 in comprising, merges all-in-one-piece cover glass tube 2 with interior pipe 1, in also comprising pipe 1 upper end extend the terminal not exclusively sealing of certain-length or in addition the socket top open the cup-shaped heat conduction object of pore and the heat exchanging segment 3 that forms; Said heat exchanging segment 3 combines together with interior pipe 1, and the top of heat exchanging segment 3 offers with the aperture 4 of pipe 1 in the balance with header or water tank internal pressure.
The top of said heat exchanging segment 3 is dome or flat-top.
Embodiment two, and with reference to Fig. 4, Fig. 5, pipe 1 was fixedly connected with interior pipe 1 in inserted said heat exchanging segment 3 lower ends.
The foregoing description is the utility model preferred implementation; But the embodiment of the utility model is not restricted to the described embodiments; Other any do not deviate from change, the modification done under spirit and the principle of the utility model, substitutes, combination, simplify; All should be the substitute mode of equivalence, be included within the protection domain of the utility model.
