Description
Technical field
The present invention relates to a kind of tubular type thermal-arrest unit of solar water heater, particularly a kind of tube type solar heat collecting unit that adopts the individual layer vacuum tube.
Background technology
Traditional solar water heater, no matter be multilayer overhead type or high-rise balcony wall-hanging, what adopt is all double-layer vacuum tube solar heat-collecting unit, the solar energy heating unit of this form is exactly the glass tube of a double-layer vacuum pumping, on the outer wall of inner tube, scribble heat absorbing coating, the inner chamber of inner tube directly communicates with water tank or thermal collecting header, after the inner layer tube wall heat absorption, the water in its chamber is directly heated, and hot water relies on convection current to enter in water tank.The solar energy heating unit of this version has the following disadvantages: 1, the double layer vacuum tube cost is high, difficulty of processing is large; 2, in the pipe, water temperature is difficult to arrive higher temperature, can't meet the needs of some industrial project heat supplies; 3, direct water in the pipe, in the cold easy bursting by freezing of body in winter, cause use cost to rise.
Summary of the invention
The purpose of this invention is to provide a kind of collecting efficiency high, safe and reliable middle high temp glass metal vacuum pipe solar heat collector.
For achieving the above object, the present invention adopts following technical scheme:
A kind of middle high temp glass metal vacuum pipe solar heat collector, it adopts tubular structure, the open end, top of body is connected with header, and the lower closed end of body is supported by collet, it is characterized in that: body is the individual layer thermal-collecting tube, in individual layer thermal-collecting tube inner chamber, be equipped with " U " type pipe, a standpipe of " U " type pipe is cold water pipe, and another standpipe is hot-water line, is fitted with the wing plate at hot-water line, wing plate cross section is arc, and the lateral surface of arc wing plate scribbles heat-sink shell; On individual layer thermal-collecting tube top, be designed with the ring of level near the madial wall border of open end position protruding, encircle protruding below and be equipped with soft shrouding, the edge-on wall introversion of shrouding forms hermetically-sealed construction with the protruding laminating of ring, and the shrouding below is circular supporting plate, and the supporting plate top is connected with vertical pull bar; Individual layer thermal-collecting tube upper port is by gland seal, and pull bar passes gland and is connected with nut thread, and nut support is on gland; Cold water pipe, hot-water line pass after shrouding, gland and minute separately with the cold water house steward, to be connected with the hot water house steward.
Above-mentioned a kind of middle high temp glass metal vacuum pipe solar heat collector is characterized in that: the wing plate is double-deck pressing structure, and hot-water line is pressed on the centre of wing plate, vacuumizes in the individual layer thermal-collecting tube; Cold water house steward's position is lower than the hot water house steward.
Middle high temp glass metal vacuum pipe solar heat collector of the present invention is prefabricated unit, first " U " type pipe, shrouding, gland in the individual layer thermal-collecting tube is placed, and realizes the sealing of upper port, then from individual layer thermal-collecting tube bottom, vacuumizes and gets final product.
After this programme is implemented, because the thermal-arrest ferrule completes in advance, therefore can realize the solid matter of thermal-collecting tube, the wing plate of arc namely can guarantee heat absorption efficiency under different irradiating angles, has saved again material.Wing plate and " U " type pipe all adopt highly heat-conductive material, and the more traditional solar energy heat collection pipe of medium temperature in it improves greatly, can realize steam supply in the area of solar radiation abundance.In addition, this programme product bug, breakage rate descend greatly, and use cost is low, and collecting efficiency is high, easy maintenance.
Below in conjunction with drawings and Examples, the present invention is further described.
The accompanying drawing explanation
Fig. 1 is the structural representation of embodiment 1.
Fig. 2 is the top view that in Fig. 1, the wing plate reaches " U " type pipe.
In figure 1, protruding 9, the shrouding 10 of collet 2, cold water pipe 3, pull bar 4, nut 5, header 6, hot-water line 7, gland 8, ring, individual layer thermal-collecting tube 11, wing plate.
