Description
Technical field:
The utility model relates to vacuum tube collector
Background technology:
Vacuum tube collector is used widely in solar water heater.Vacuum tube collector of the prior art all is directly to be communicated with water in the water tank with the body of vacuum tube, utilizes the temperature difference proportion difference of water, forms the convection current of water between body and water tank naturally, and the water in the whole water tank is heated up.But there are the following problems in concrete the use:
1, efficient is low.Along with the continuous intensification of water in the water tank, the temperature difference of water is more and more littler between body and water tank, so that convection velocity each other is more and more slower, thereby causes the great loss on the thermal efficiency.
2, fragile.Water-filled vacuum body very easily causes at extremely frigid zones and freezes damage; The vacuum body makes vacuum tube breakage easily with the temperature difference of the interior water of pipe; The vacuum body directly bears hydraulic pressure because of directly being communicated with water tank.So when the vacuum tube body damages, just cause serious seepy question.
Summary of the invention:
Technical problem to be solved in the utility model is to avoid above-mentioned existing in prior technology problem, provides a kind of thermal efficiency height, tool to avoid the direct-heating type vacuum tube collector of seepy question.
The technical scheme that the utility model technical solution problem is adopted is:
Design feature of the present utility model is the water pipe that is provided with at least one excellent heat conductivity in vacuum sleeve, on the lateral wall of water pipe, link the ring-type heat carrier is arranged, in addition good thermal insulation material is arranged on the madial wall of ring-type heat carrier, be provided with mouth of pipe plug in the mouth of pipe place of vacuum sleeve and form closed cavity; The water inlet pipe mouth of water pipe and effluent pipe mouth run through mouth of pipe plug, and heated material is positioned at water pipe.
Technical parameter by the traditional type vacuum tube collector that is circulated in the market can recognize easily that the sky of such vacuum tube collector shines temperature can reach 260 degree Celsius, and the utility model has utilized its empty direct high temperature that is obtained that shines just.Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, because the direct heat energy that the ring-type heat carrier in the vacuum sleeve is accepted, stop in the inner chamber body of conducting heat to vacuum sleeve via the heat insulation material on the ring-type heat carrier inwall, so heat energy is able to the heating of the water transmission in water pipe rapidly, therefore can improve the thermal efficiency effectively.
2, heated water can form flowing of directed constant speed in the utility model in water pipe, and the mobile of this directed constant speed is to utilize the pressure differential between water inlet pipe mouth and effluent pipe mouth to form.Simultaneously, hydraulic pressure is directly born by water pipe, and is the cavity of dry sealing in the vacuum sleeve, has thoroughly solved the seepy question that breaks and cause because of vacuum sleeve.
Fig. 1 is the utility model structural representation.
Fig. 2 is another example structure schematic diagram of the utility model.
Fig. 3 is the utility model schematic cross-section.
Number in the figure: 1, vacuum sleeve, 2, water pipe, 3, the ring-type heat carrier, 4, mouth of pipe plug, 5, water inlet pipe mouth, 6, effluent pipe mouth, 7, heat insulation material, 8 solar selective absorbing coatings.
The specific embodiment:
Referring to Fig. 1, Fig. 3, present embodiment is the water pipe 2 that is provided with at least one excellent heat conductivity in vacuum sleeve 1, on the lateral wall of water pipe 2, link ring-type heat carrier 3 is arranged, good thermal insulation material 7 is arranged on the madial wall of ring-type heat carrier 3, to stop that thermal energy conduction is to the inner chamber body of vacuum sleeve 1, be beneficial to heat energy and be able to the heating of the water transmission in water pipe 2 rapidly, reach the purpose of giving full play to the thermal efficiency.Be provided with mouth of pipe plug 4 in the mouth of pipe place of vacuum sleeve 1 and form closed cavity; The water inlet pipe mouth 5 and the effluent pipe mouth 6 of water pipe 2 run through mouth of pipe plug 4 in addition, and heated material is positioned at water pipe 2.
As shown in Figure 1, the single-pass vacuum sleeve that vacuum sleeve 1 in the present embodiment is end sealing, an end is uncovered, be positioned at the two ends of the water pipe 2 of its excellent heat conductivity, respectively as water inlet pipe mouth 5 and effluent pipe mouth 6, and a uncovered end of the single-pass vacuum sleeve 1 that coexists runs through mouth of pipe plug 4 and stretches out.
Referring to Fig. 2, vacuum sleeve 1 also can be the straight-through vacuum sleeve pipe of open at both ends as shown in Figure 2, be positioned at the two ends of the water pipe 2 of its excellent heat conductivity, respectively as water inlet pipe mouth 5 and effluent pipe mouth 6 and run through mouth of pipe plug 4 from the two-port of straight-through vacuum sleeve pipe 1 respectively and stretch out.
In concrete the enforcement, can between the water inlet pipe mouth 5 of water pipe 2 and effluent pipe mouth 6, form pressure differential.The heated water of this pressure official post forms flowing of directed constant speed in water pipe 2.
As depicted in figs. 1 and 2, in concrete the enforcement, solar selective absorbing coating 8 is arranged on the outer wall of ring-type heat carrier 3.Also visual demand is coated on solar selective absorbing coating 8 on the outer wall of inner tube of vacuum sleeve 1.
In the present embodiment, heated material can be its a kind of material in liquid or the gas in the water pipe 2.
