Abstract
The invention discloses a high-capacity U-shaped channel evacuated tube collector which mainly comprises an aluminum profile frame, a U-shaped channel profile, an evacuated collector tube, a liquid separation flow channel, a liquid separation flow channel shell profile and an insulation layer. The U-shaped channel profile is the pure aluminum integrally-formed U-shaped channel and is of a circular structure. Each U-shaped channel is fastened to the liquid separation flow channel in a spiral tightening sealed mode and sealed in an insulation shell of the liquid separation flow channel. The insulation layer is arranged between the liquid separation flow channel and the insulation shell of the liquid separation flow channel. The U-shaped channel profile is sleeved with the evacuated collector tube. The large-diameter U-shaped channels are formed by means of the characteristic that aluminum profile forming is convenient and have the medium capacity which is five times that of a traditional U-shaped tube collector. Due to the heat conductive face and the integrated U-shaped channel aluminum profile, the heated superficial area is formed to the largest limit, the heat collection efficiency is improved, the outer diameter is smaller than or equal to the inner diameter of a glass evacuated collector tube, and the heat transfer efficiency is redoubled due to the fact that heat conduction distance is greatly shortened.
Description
Technical field
The present invention relates to a kind of U-shaped passage vacuum tube collector technical field, especially heat-conducting medium forms same Cheng Xunhuan through the bigbore U-shaped passage of each root and separatory runner, and bigbore U-shaped passage is holding the U-shaped passage vacuum tube collector of large capacity of the dielectric capacity of 5 times of common U-shaped pipe heat collectors.
Background technology
The minimum bending radius of the copper pipe that existing U-shaped pipe heat collector is subject to is limit, the internal diameter of copper pipe is general≤6mm, the dielectric capacity of 1 square metre of collector area only has 2.5 liters, for increasing heat transfer effect, U-shaped copper pipe is embedded in the flake aluminum of Ω shape, and simple and easy coarse physical contact structure greatly reduces the heat transference efficiency of vacuum heat collection pipe for U-shaped pipe.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides the U-shaped passage vacuum tube collector of the large capacity of a kind of aluminium section bar, to overcome because the Cu and Al combination place little thermal resistance of contact area is large, the shortcoming that dielectric capacity is little.
For realizing above object, by the following technical solutions: the large U-shaped passage vacuum tube collector of capacity, mainly comprises edge frame made of aluminum profiles, U-shaped passage section bar, vacuum heat collection pipe, separatory runner, separatory runner shell sectional bar, heat-insulation layer; Described U-shaped passage section bar is the one-body molded U-shaped passage of fine aluminium section bar, U-shaped passage section bar is circular configuration, each root U-shaped passage is anchored on separatory runner with screw-tightened seal form respectively and is closed in separatory runner lagging casing, between separatory runner and separatory runner lagging casing, be provided with heat-insulation layer, vacuum heat collection pipe is sleeved on U-shaped passage Surface of profile.
What described edge frame made of aluminum profiles adopted is square tube aluminium section bar.
Described separatory runner is the semicircle aluminium section bars of two endoporus.
Described separatory runner shell sectional bar is square tube section.
Described heat-insulation layer adopts polyurethane foam heat-insulating heat-preserving material.
Described vacuum heat collection pipe is to be evacuated between two sleeve pipes and two sleeve pipe, and scribbles the high-boron-silicon glass vacuum heat collection pipe of coating for selective absorption at the outer surface of inner tube.
Beneficial effect of the present invention: utilizing the aluminium section bar characteristic easily that is shaped, form the U-shaped passage of heavy caliber, is the dielectric capacity of 5 times of traditional U-shaped pipe heat collectors. Due to the aluminium section bar of thermal conductive surface and U-shaped passage one integrated mass, form to greatest extent heated surface area and improve collecting efficiency, its external diameter is less than or equal to the internal diameter of glass heat-collecting vacuum tube, makes heat transference efficiency multiplication because greatly having shortened heat conducting distance.
