Abstract
A vacuumed solar energy collector tube for a water heater comprises an inner glass tube and an outer glass tube which are concentric, wherein, selective adsorption wax is deposited on the outer surface of the inner tube to form a heat absorption body; the sandwich layer between the inner and the outer tubes is highly vacuumed; the whole vacuumed solar energy collector tube adopts a one-end closed structure and is characterized in that a copper pipe is arranged in the inner tube and an aluminum sheet is warped outside the inner tube; the open side of the vacuumed solar energy collector tube is coved by a rubber film; and a copper cap is fixed on the copper pipe after penetrating the rubber film. The vacuumed solar energy collector tube adopts the copper pipe to conduct heat, water can not enter the vacuumed tube, so as to avoid explosion, inner deposition is avoided and the product service life is prolonged.
Description
Technical field
The present invention relates to the heater element of solar water heater, particularly a kind of vacuum solar collector tubes.
Background technology
The most frequently used device is a kind of vacuum solar collector tubes above the solar water heater; What generally use now is the full glass solar vacuum heat collection pipe; It is made up of inside and outside two concentric circles glass tubes; Selectivity with high-absorbility and low-launch-rate absorbs cured being deposited on and constitutes absorber on the inner tube outer surface, is pumped into high vacuum between the inner and outer pipes interlayer, and its shape is as an elongated inner flask.Its operation principle is that solar energy sees through outer glass and shines on the inner tube outer surface absorber and convert heat energy into; Heat the heat-transfer fluid in the inner glass tube then; Owing to vacuumized between the interlayer, effectively reduce the heat loss that ambient is scattered and disappeared, collecting efficiency is improved.Specifically on solar water heater, above-mentioned heat-transfer fluid is exactly the water that is connected in the storage tank.
The shortcoming of this vacuum solar collector tubes is: be easy to generate bombing when not having water in the thermal-collecting tube and damage thermal-collecting tube, in addition, the long-term water inlet of inner tube wall also can produce incrustation scale, reduces heating efficiency, reduction of service life.
The utility model content
The purpose of the utility model is in order to overcome the defective of the described existing glass vacuum solar collector tubes of background technology, to invent a kind of suitable solar water heater glass vacuum solar collector tubes that use, long service life.
The vacuum solar collector tubes of the utility model; Contain inside and outside two concentric circles glass tubes and constitute, selectivity absorbs cured being deposited on and constitutes absorber on the inner tube outer surface, is pumped into high vacuum between the inner and outer pipes interlayer; It is characterized in that: interior pipe inside is provided with copper pipe, the coated outside aluminium flake; The open side of vacuum solar collector tubes is sealed with rubber membrane, and copper pipe is fixed with the copper cap after passing rubber membrane.
Preferably, the copper cap is provided with protruding threaded rod.
When the vacuum solar collector tubes of the utility model was used on the solar water heater, as boundary, the copper cap inserted water tank and contacts with water with rubber membrane.After the outer side absorbent solar energy of the interior pipe of vacuum solar collector tubes, transfer of heat absorbs to aluminium flake, and aluminium flake is passed to copper pipe again and finally is transmitted to the copper cap and comes the cold water in the heating water tank.The structure of threaded rod can improve the contact area of copper cap and water, improves the efficiency of heating surface.
The vacuum solar collector tubes of the utility model has been realized vacuum, does not intake in the pipe, can effectively avoid phenomenons such as bombing, incrustation, the service life of improving whole solar water heater.
Description of drawings
Fig. 1, structure chart of the present invention;
Fig. 2, the present invention are used for the embodiment of solar water heater.
The specific embodiment
Like Fig. 1, the utility model is that the outer tube 1 of glass material, interior pipe 2 covers are set to shell, and interlayer vacuumizes, and outer tube 1 light transmittance is high, and the selectivity with high-absorbility and low-launch-rate absorbs in cured being deposited on and constitutes absorber on pipe 2 outer surfaces.In interior pipe 2 inside, prior art is that cavity is used for arranging heat-conducting fluid, is exactly water in the reality, among the present invention, is to arrange an outside to coat the copper pipe 4 of aluminium flake 3, and copper pipe 4 extends to outside the shell, and the top is provided with copper cap 5.The shell aperture place is provided with rubber membrane 6 and is used for the water-tight that is connected with water-heater water tank, nature, and copper cap 5 is arranged in the outside of rubber membrane 6.Because when being installed on solar water heater, copper cap 5 is calandrias, in order to increase the contact area with water, improve heat generation rate, the top of copper cap 5 also is provided with protruding threaded rod 7.
Like Fig. 2, when the utility model is installed on the solar water heater, a plurality of vacuum solar collector tubes are installed on the water tank 7, the copper cap 5 of thermal-collecting tube reaches in the water tank and contacts with water, and rubber membrane 6 is as sealing device.Shine upon, temperature raises in the vacuum tube, and aluminium flake 3 absorption temperature are passed to copper pipe 4, and copper pipe 4 conducts again gives the copper cap 5 heatings, heats cold water.This vacuum solar collector tubes inside does not intake, and can improve service life, avoids anhydrous bombing.
Another kind of embodiment: do not use aluminium flake, directly adopt the copper pipe heat absorption conductive, can realize the object of the invention equally.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and modification, these non-obvious improvement and modification also should be regarded as protection scope of the present invention.
