Abstract

High temperature heat collector vacuum tube, vacuum tube is mounted on header, the vacuum tube includes inner tube, vestlet, vacuum interlayer and supporting member, flow channel of the inner tube as water, is vacuum interlayer between inner tube and vestlet, and inner tube is fixed on vestlet by supporting member, the vestlet is divided into upper tube half and lower tube half, inner tube is installed, lower tube half is vacant, and the appearance of upper tube half receives upwardly sunlight in upper tube half.Only vestlet top half namely facing upwards the sun part setting water flow channel-inner tube, water in this way in inner tube reduces, there is water in the part that only can receive sunlight, lower half portion is as vacuum interlayer, it is opposite the water-filling of lower half portion the case where, this kind design can reduce absorption of the lower half portion cold water to hot water energy, and heat utilization efficiency improves, and the water in inner tube can reach higher temperature faster.

Description

High temperature heat collector vacuum tube
Technical field
The utility model relates to heat collector technical fields, in particular to high temperature heat collector vacuum tube.
Background technique
Solar water heater is the heating device for converting solar energy to thermal energy, by water from low-temperature heat to high temperature, with Meet hot water of the people in life, production to use.Solar water heater is divided into vacuum pipe solar water by structure type Device and flat solar water heater occupy the market share of the country 95% mainly based on vacuum pipe solar water heater. Electron tubes type domestic solar water heater is made of the related spare and accessory parts such as thermal-collecting tube, water tank and bracket, and solar energy is converted Evacuated collector tube is relied primarily at thermal energy, the principle that evacuated collector tube utilizes hot water floating cold water to sink makes water generate microcirculation And obtain required hot water.When specifically used, vacuum tube generally tilts installation, in the prior art, is arranged in inner glass tube in cover In glass tube, the cross section of inner glass tube is circle.Howsoever installation is fixed, and the downward part of cover glass tube almost contacts Less than sunlight, and top half can absorb sunlight part transfer heat to the medium in inner glass tube (water) after, cover glass Not only the lower half portion of glass pipe cannot absorb heat the heat that heat is provided also for inner glass tube and can absorb in inner glass tube, cause heating power It is not high with rate.
Utility model content
To overcome problems of the prior art, the utility model provides a kind of high temperature heat collector vacuum tube.
The technical solution adopted by the utility model to solve its technical problems is that: this kind of high temperature heat collector vacuum tube, very Blank pipe is mounted on header, and the vacuum tube includes inner tube, vestlet, vacuum interlayer and supporting member, and inner tube is logical as the flowing of water Road is vacuum interlayer between inner tube and vestlet, and inner tube is fixed on vestlet by supporting member, and the vestlet is divided into upper tube half and lower half It manages, inner tube is installed in upper tube half, lower tube half is vacant, and the appearance of upper tube half receives upwardly sunlight.
Further, said inner tube is U-tube, and inner tube is divided into water tube portion and water outlet tube portion, water inlet tube portion and The cross section for being discharged tube portion is sector, and fan-shaped arc surface is close to upper tube half.
Further, the corresponding arc chord angle of the sector is 90 ° to 135 °.
Further, the upper half inside pipe wall has heat absorbing coating.
Further, the vestlet inner wall is equipped with heat absorbing coating.
To sum up, the above-mentioned technical proposal of the utility model has the beneficial effect that:
Only vestlet top half namely facing upwards the sun part setting water flow channel-inner tube, in this way Water in inner tube reduces, and there is water in the part that can only receive sunlight, and lower half portion is opposite in lower half as vacuum interlayer The case where dividing water-filling, this kind design can reduce absorption of the lower half portion cold water to hot water energy, and heat utilization efficiency improves, in inner tube Water can reach higher temperature faster.
Detailed description of the invention

Fig. 2 is the structural schematic diagram of single vacuum tube;
Fig. 3 is the cross section view of vacuum tube;
Fig. 4 is the partial enlarged view of C portion in Fig. 2.
In figure:
1 vacuum tube, 2 headers, 3 inner tubes, 31 water inlet tube portions, 32 water outlet tube portions, 4 vestlets, 5 vacuum interlayers, 6 upper half Pipe, 7 lower tube halfs.
Specific embodiment
It is described in detail below in conjunction with feature and principle of the attached drawing to the utility model, illustrated embodiment is only used for explaining The utility model not limits the protection scope of the utility model with this.
As shown in Figure 1, vacuum tube 1 is mounted on header 2, and when specifically used, the inclination installation of vacuum tube 1.
As shown in figs 2-4, vacuum tube 1 includes inner tube 3, vestlet 4, vacuum interlayer 5 and supporting member.Inner tube 3 is U-shaped glass Glass pipe, flow channel of the inner tube 3 as water.Inner tube 3 is divided for water inlet tube portion 31 and water outlet 32 two parts of tube portion.Vestlet 4 divides For upper tube half 6 and lower tube half 7, inner tube 3 is installed in upper tube half 6, lower tube half 7 is vacant, and the appearance of upper tube half 6 receives upwardly sun Light.3 sets of inner tube in vestlet 4, be vacuum interlayer 5 between inner tube 3 and vestlet 4, inner tube 3 is fixed on vestlet 4 by supporting member.
Wherein, the cross section of water inlet tube portion 31 and water outlet tube portion 32 is sector, and fan-shaped corresponding arc chord angle α is 90 ° to 135 °.Specific arc chord angle design can be selected according to different application region lighting angle difference.Fan-shaped arc surface Close to upper tube half 6,6 inner wall of upper tube half has heat absorbing coating or 4 inner wall of vestlet to be equipped with heat absorbing coating.Pass through each vacuum tube 1 in this way Water later can be brought rapidly up to higher temperature, can be applied to the place of high temperature water emphatically.
Only vestlet 4 top half namely facing upwards the sun part setting water flow channel-inner tube 3, this Water in sample inner tube 3 reduces, and there is water in the part that can only receive sunlight, and lower half portion is opposite under as vacuum interlayer 5 The case where half part water-filling, this kind design can reduce absorption of the lower half portion cold water to hot water energy, and heat utilization efficiency improves, interior Water in pipe 3 can reach higher temperature faster.
Above-described embodiment is only the description carried out to preferred embodiments of the present invention, not to model of the invention It encloses and is defined, under the premise of not departing from the spirit of the design of the utility model, relevant technical staff in the field is to the utility model Various changes and improvements, should all expand in protection scope determined by the utility model claims book.
