Description

A kind of four target titanium thermal-collecting tubes

Technical field

This utility model relates to solar energy heat collection pipe technical field, is specially a kind of four target titanium thermal-collecting tubes.

Background technology

Solar energy heat collection pipe is the core of solar water heater, the glass liner for vacuum flask of his structure such as same elongation, is vacuum between ectonexine. The surface of inner glass tube utilizes special warfare scribble spectral selective absorbing coating, be used for absorbing solar radiant energy to greatest extent. Irradiating through sunlight, photon strikes coating, solar energy changes into heat energy, and water absorbs heat from coating, and water temperature raises, and density reduces, and hot water moves upward, and heavy cold water declines. Hot water is always positioned at top, namely in water tank. In solar water heater, the ramp case of hot water is little with ambient temperature relation, depends primarily on illumination. When any one faucet opened between kitchen or bathing, the hot water in water heater just relies on natural-drop to flow out, and drop is more big, and hydraulic pressure is more high. Currently, the corporate boss of domestic production shell wants strong promise, unit to rise, Yao Huideng enterprise, the corporate boss producing vacuum tube wants the enterprise such as strong promise new material, precious light thermal-collecting tube, mainly there are two kinds of types, one is do not leak water in pipe, one is leak water in pipe, and traditional vacuum tube is all leak water in pipe, and the release of the release of double; two vacuum and " heat pipe is direct insertion " vacuum tube all makes not leak water in glass tubing.

But, traditional thermal-collecting tube is mainly copper, steel, aluminum three target membrane system, and owing to the material behavior of above three targets causes three target thermal-collecting tubes, when normal production, absorbance is below 93%, and service life is short, unstable. Further, traditional thermal-collecting tube is due to the particularity of its structure so that the refractive index of interior pipe coating, reflectance are not high, and the light-receiving area of outer tube is limited so that thermal absorptivity is not high.

Utility model content

The purpose of this utility model is in that to provide a kind of four target titanium thermal-collecting tubes, with the problem solving to propose in above-mentioned background technology.

For achieving the above object, this utility model provides following technical scheme: a kind of four target titanium thermal-collecting tubes, including interior pipe and outer tube, said inner tube is plugged on the inner chamber of outer tube, and the bottom of interior pipe is connected by flexible clamp piece is fixing with the inner chamber bottom of outer tube, vacuum chamber is formed between said inner tube and outer tube, the outer wall of said inner tube is integrally formed with triangular hill, and the outer wall of triangular hill is coated with heat absorbing coating, described heat absorbing coating includes copper film system, the upper surface synthesis of described copper film system has steel membrane system, the upper surface synthesis of described steel membrane system has aluminum film system, the upper surface synthesis of described aluminum film system has titanium film system, the outer wall of described outer tube is also integrally formed with semi-cylindrical hill.

Preferably, described flexible clamp piece is " U " type shape, and the bottom of flexible clamp piece is fixed with the inner chamber bottom of outer tube and is connected.

Preferably, the cross section of described triangular hill triangle in obtuse angle.

Compared with prior art, the beneficial effects of the utility model are: this four targets titanium thermal-collecting tube simple in construction, add titanium target and form four target membrane systems so that the thermal-collecting tube absorbance height produced can reach more than 95% on the basis of original three target techniques; Aging resistance, corrosion-resistant; Invariant color after aerofluxus; Absorbance and emissivity are stable so that this thermal-collecting tube practicality is higher. And, at the outer wall of interior pipe integrally formed with triangular hill, can effectively change the refractive index of heat absorbing coating, make endothermic effect better, and at the outer wall of outer tube integrally formed with semi-cylindrical hill, the area that outer tube receives light is increased, thus effectively improving absorptivity so that the Heat-collecting effect of this thermal-collecting tube is better.
