Abstract
The utility model relates to a vacuum tube solar collector, including vacuum tube, u venturi tube, circulating pump, heat exchanger, wherein: the u venturi tube falls into two examples, and the u venturi tube between every example is established ties together, and all u venturi tubes all incline to set up, and the vacuum tube slope is invertd on the u venturi tube, the both ends of two routine series connection u venturi tubes, and merge becomes slope inversion formula vacuum tube heat collector together. The one end of heat exchanger is connected through the circulating pump to the one end of heat collector, and the other end of heat exchanger is manage and is said and constitute vacuum tube solar energy collection heat transfer circulation circuit by an other end of getting back to the heat collector. The manufacture craft has been simplified in the port blow -by of vacuum tube, has reduced sealing material, is favorable to reduce cost, each example uses a copper pipe to bend to the venturi tube as series connection u in succession, and technology is simple and convenient, reduces the welding volume, adopt u venturi tube medium reserves to significantly reduce, start soon, effective heat absorption efficiency that improves.
Description
Technical field
This utility model belongs to Application of Solar Energy field, especially solar thermal collector.
Background technology
All-glass solar vacuum tubular collector, low price, good heat insulation, output temperature is high, but storing substantial amounts of medium in vacuum tube, medium is more many, and stored heat is more many, this results in starting slowly, and the heat stored is not fully utilized, thus reducing collecting efficiency. Having a kind of improvement is arrange copper u shape pipe at the inner tube there of vacuum tube, so, greatly reduces medium storage reserves, owing to u shape pipe is relatively thin, exists for very big space in vacuum tube, and this space is full of air. Now, vacuum tube two kinds of forms are installed, one is vertical, and the mouth of pipe of vertical installation is upwards; Another kind is that horizontal type is installed, and horizontal type is to be horizontally disposed with by vacuum tube, and being usually 25 becomes string, and two row share company's case becomes one group. No matter it is vertical or horizontal type, is required between the mouth of pipe and the u shape pipe of vacuum tube sealing, not so, to produce convection current after the air heats in pipe thus dissipated heat, be substantially reduced efficiency. But this sealing is again relative, because the air of the inside to expand when high temperature produces very big pressure, go out sealing member, outwards breathe out hot-air, contraction of gas during low temperature, form negative pressure, sucking cold air, produce breathing phenomenon, the cold air of suction to be gone to the tail end of vacuum tube and absorb heat, form another expansion, constituting step breathing, losing heat, thus reducing the efficiency of solar heat collector, therefore, also need to improve.
Summary of the invention:
The purpose of this utility model, is in that to provide a kind of vacuum tube solar heating element, is provided with u shape pipe, need not seal between u shape pipe and the mouth of pipe of vacuum tube in the vacuum tube of this heat collector, and the air inside vacuum tube is without convection current.
Technical scheme: a kind of vacuum tube solar heating element, including vacuum tube, u shape pipe, circulating pump, heat exchanger; Wherein: u shape pipe is divided into two examples, the u shape pipe between every example is cascaded, and all of u shape pipe is all obliquely installed, vacuum tube oblique inverted on u shape pipe, two examples series connection u shape pipes two ends, combine and become oblique inverted formula vacuum tube collector.One end of heat collector connects one end of heat exchanger through circulating pump, and the other end of heat exchanger returns to the other end of heat collector through pipeline, constitutes vacuum pipe solar thermal-arrest recuperated cycle loop.
Further described the above of u shape pipe is welded with the absorber plate possessing coating for selective absorption.
Operation principle: because vacuum tube is oblique inverted, tail end is upper, and opening is downward, and hot-air is doted on cover by tail end, it is impossible to flowing, the lower end blow-by of vacuum tube, lowers efficiency without producing (or left and right) convection current up and down.
Beneficial effect: the port blow-by of vacuum tube, simplifies processing technology, decreases encapsulant, advantageously reduce cost; Each example becomes series winding u shape pipe, simple process by a copper pipe continuous bend, reduces welding capacity; Adopt u shape pipe medium reserves to greatly reduce, start fast, efficiency is greatly improved.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Shown in figure: vacuum tube 1, u shape pipe 2, circulating pump 3, heat exchanger 4.
Detailed description of the invention
The detailed description of the invention of this practicality is described below in conjunction with accompanying drawing 1.
A kind of vacuum tube solar heating element, including vacuum tube 1, u shape pipe 2, circulating pump 3, heat exchanger 4 is wherein: u shape pipe is divided into two examples, u shape pipe between every example is cascaded, all of u shape pipe is all obliquely installed, vacuum tube oblique inverted on u shape pipe, two examples series connection u shape pipes two ends, combine and become oblique inverted formula vacuum tube collector; One end of heat collector connects one end of heat exchanger 4 through circulating pump 3, and the other end of heat exchanger 4 returns to the other end of heat collector through pipeline, constitutes oblique inverted formula vacuum pipe solar thermal-arrest recuperated cycle loop. Vacuum tube also should have support to fix.
