Abstract
The utility model relates to a solar water heater technology, in particular to a solar vacuum tube. The hot water pipe of the existing solar water heater is a vacuum tube, and frictional resistance is produced by cold water flowing from the tank into the vacuum tube and hot water flowing from the tube into the tank, and as a result the cycle numbers and the heating efficiency are reduced. The utility model provides a solar vacuum tubes, a mirror stainless steel plate is arranged in the tube, which divides the inner cavity into upper and lower two cavities with bottom communicated. The utility model solves the problems existed in the existing technology of low cycle numbers of cold and hot water, low heating efficiency, easy frost cracking and difficult cleaning of the scale on the tube wall, and has the advantages of high heating speed, high efficiency, easy cleaning, cold resistance and etc.
Description
Technical field
The utility model relates to technical field of solar water heaters, is specifically related to a kind of solar energy vacuum tube.
Background technology
Because the energy of solar water heater is from the sun, its non-environmental-pollution, no potential safety hazard, the energy can infinitely use; And its long service life, the critical piece vacuum tube is about 15 years service life, has realized the least cost hot-water supply, and therefore, solar water heater is widely used.The hot-water line of existing solar water heater is exactly a vacuum tube, when cold water when water tank enters vacuum tube, the hot water that can and enter water tank from vacuum tube produces frictional resistance, causes the cycle-index of hot and cold water to reduce, and has reduced the efficient of heating; And the hot water in the vacuum tube and the cold water in the water tank mixes water easily at the vacuum mouth of pipe, is unfavorable for the hot and cold water exchange.In the winter of extremely frigid zones, the water capacity in the vacuum tube is easily frozen, and can cause the vacuum tube explosion, if think anti-bursting by freezing, can only be when cold, and the water in the emptying water tank.Incrustation scale on the existing vacuum tube tube wall is easy-clear not also.
Summary of the invention
The utility model purpose is to provide a kind of solar energy vacuum tube, and few to overcome the hot and cold water cycle-index that prior art exists, the efficiency of heating surface is low, easily bursting by freezing, and the tube wall incrustation scale is the problem of easy-clear not.
For achieving the above object, the technical solution of the utility model is:
A kind of solar energy vacuum tube comprises body 1, and its special character is: be provided with one in the described body 1 inner chamber is divided into up and down two cavitys, and two mirror face stainless steel plates 2 that the cavity bottom is communicated with.
Above-mentioned mirror face stainless steel plate 2 is a long strip type, and its length is consistent with the length of vacuum tube, and its width is wideer 1～10 millimeter than vacuum tube internal diameter width, is fixed in the vacuum pipe inner cavity.
Above-mentioned mirror face stainless steel plate 2 exceeds 10～30 centimetres of the vacuum tube mouths of pipe.
The lateral cross section of above-mentioned mirror face stainless steel plate 2 is shaped as the V font.
The utility model compared with prior art has the following advantages:
1, mirror face stainless steel plate smooth surface, little with the frictional resistance of hot and cold water, the circulation of hot and cold water is accelerated, and has improved the efficient of heating;
2, because the mirror face stainless steel plate is divided into two parts with space in the vacuum tube, wherein a part is over against the sun, so only needs in the heating tube water of half, and the temperature difference of hot and cold water is big, and density contrast is big, and the power that water flows is big, the firing rate quickening;
3, the mirror face stainless steel plate exceeds the vacuum tube part, can play the deflector effect in vacuum tube and the exchange of water tank hot and cold water, makes hot and cold water be difficult for mixing water at the vacuum mouth of pipe;
4, since vacuum tube inwall surperficial Paint Gloss than mirror face stainless steel plate so incrustation scale is difficult attached on the tube wall, but transferred on the surface of mirror face stainless steel plate, when removing incrustation scale, only need the mirror face stainless steel plate is taken out, gently knock on the ground, incrustation scale just comes off naturally;
5, the mirror face stainless steel plate can also play the effect of heat conduction, with the temperature conduction of warm water in the water tank in vacuum tube, guarantee vacuum tube winter of cold not by bursting by freezing, i.e. secondary heat conduction (DCR) technology.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the structural representation of another kind of embodiment of the present utility model.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model is a kind of solar energy vacuum tube, its structure comprises body 1, one mirror face stainless steel plate 2 is set in body 1, mirror face stainless steel plate 2 can be long strip type, its length is consistent with the length of vacuum tube, and its width is wideer 1～10 millimeter than vacuum tube internal diameter width, is fixed in the vacuum pipe inner cavity; Mirror face stainless steel plate 2 is divided into two cavitys up and down that the bottom is communicated with inner chamber, when the water in the vacuum tube upper cavity is heated, hot water flows into casing from the bottom to top, thereby make the cold water in the water tank flow into vacuum tube from top to bottom, and enter upper cavity, so only the water of half in the need heating tube from the bottom of vacuum tube, the temperature difference of hot and cold water is big, density contrast is big, and the power that water flows is big, and firing rate is accelerated.And mirror face stainless steel plate 2 smooth surfaces, little with the frictional resistance of hot and cold water, the circulation of hot and cold water is accelerated, and has improved the efficient of heating.
Referring to Fig. 1, mirror face stainless steel plate 2 exceeds vacuum tube 20cm, and exceeding part can play the deflector effect in vacuum tube and the exchange of water tank hot and cold water, make hot and cold water be difficult for mixing water at the vacuum mouth of pipe.When cold in the winter time, mirror face stainless steel plate 2 can also play the effect of heat conduction, and the temperature of the water in the water tank that will heat in the time of will daytime sunlight being arranged is delivered in the vacuum tube, guarantees that vacuum tube is not by bursting by freezing.
Referring to Fig. 3, Fig. 3 is the schematic diagram of the lateral cross section shape V font of mirror face stainless steel plate 2, the mirror face stainless steel plate of V-shape has the elastic telescopic of 1～3mm on lateral cross section, for mirror face stainless steel plate and vacuum tube are fitted closely, both sides at V-shape mirror face stainless steel plate are provided with " V " glyph edges, thereby make the mirror face stainless steel plate 2 that is connected in inner chamber more firm.
Use when installing, mirror face stainless steel plate 2 is directly inserted vacuum tube, vacuum tube is being installed on the solar energy hot water tank, mirror face stainless steel plate 2 one sides of vacuum tube are upwards got final product.
The vacuum tube inwall is surperficial more Paint Gloss than mirror face stainless steel plate 2, so incrustation scale is difficult attached on the tube wall, but has transferred on the surface of mirror face stainless steel plate 2, when removing incrustation scale, only need mirror face stainless steel plate 2 is taken out, gently knock on the ground, incrustation scale just comes off naturally.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
