A pressure-bearing solar vacuum glass heat pipe heat collecting device comprises a vacuum glass heat pipe (2), a heat collector header (3) and a metal flow channel pipe (4) positioned in the heat collector header (3). The metal flow channel pipe (4) consists of a stainless steel main flow channel square pipe (6) and connecting pipes (5) welded at two ends of the stainless steel main flow channel square pipe (6); holes (6-1) and (6-2) are punched on two sides of the stainless steel main flow channel square pipe (6); flanges are arranged on the holes (6-1) and (6-2); a heat exchange casing pipe (7) is connected to the inner sides of the flanges in a brazed manner by the aid of special dissimilar metal brazing materials and extends into the stainless steel main flow channel square pipe (6); and a condensing end of the vacuum glass heat pipe (2) is inserted into the heat exchange casing pipe (7). The pressure-bearing solar vacuum glass heat pipe heat collecting device has the advantages of simple structure, convenience for installation, high heat efficiency and low manufacturing cost.
Description
Technical field
The utility model relates to a kind of pressure-bearing solar vacuum glass heat collector tube device, belongs to solar thermal collector and makes the field.
Background technology
The vacuum-tube heat-pipe type solar thermal collector of present majority, adopt red copper material super heat-conductive pipe tube core, vacuum tube interpolation aluminium heat absorption fin, the condensation end of super heat-conductive pipe tube core is connected with the runner of red copper material then, control transfer of heat will be conducted several times through the heat of vacuum tube, earlier by the inwall of glass tube to aluminium heat absorption fin, absorb heat fin to super heat-conductive pipe by aluminium again, at last by super heat-conductive pipe to metal flow passage, by the medium in the metal flow passage heat is taken away at last.And the diameter of the super heat-conductive pipe tube core condensation end of employing is generally φ 14-22mm at present, and heat exchange area is less.Through heat conducting decay several times,, caused the thermal efficiency of heat collector to be affected like this adding there is not enough big heat exchange area on heat pipe tube core condensation end and the runner.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, provide a kind of simple in structure, easy for installation, the thermal efficiency is high, the pressure-bearing solar vacuum glass heat collector tube device of low cost of manufacture.
The technical scheme that realizes above-mentioned purpose is: a kind of pressure-bearing solar vacuum glass heat collector tube device, comprise vacuum glass heat pipe, heat collector header and the metal flow deferent that is arranged in the heat collector header, the metal flow deferent is made up of primary stainless steel runner square tube and the tube connector that is welded on primary stainless steel runner square tube two ends, two side blows of primary stainless steel runner square tube are porose, has flange on the hole, and be welded with heat exchange sleeve in the flange inboard, and heat exchange sleeve stretches in the primary stainless steel runner square tube, and the condensation end of vacuum glass heat pipe is inserted in the heat exchange sleeve.
Described heat exchange sleeve is a copper tube.
The stainless steel tube connector adopts special-purpose heterogenous metal brazing material soldering to connect with heat exchange sleeve.
After adopting technique scheme, the heat of vacuum tube inwall directly is carried to condensation end by the medium of vacuum glass heat pipe, only through a thermal convection current diabatic process, and the diameter of the heat exchange sleeve of metal flow deferent has improved the thermal efficiency of heat collector effectively much larger than φ 14mm.Because the heat collector main body adopts nonmetallic glass material, the more conventional vacuum-tube heat-pipe type of cost solar thermal collector also greatly reduces.Because the metal flow deferent is made up of primary stainless steel runner square tube and the tube connector that is welded on primary stainless steel runner square tube two ends, belong to full welded seal structure, heat collector can bearing operation.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Shown in Fig. 1～4, a kind of pressure-bearing solar vacuum glass heat collector tube device, comprise vacuum glass heat pipe 2, heat collector header 3 and the metal flow deferent 4 that is arranged in heat collector header 3, metal flow deferent 4 is formed by primary stainless steel runner square tube 6 with by the tube connector 5 that argonaut welding is welded on primary stainless steel runner square tube 6 two ends, the porose 6-1 of front and back two side blows of primary stainless steel runner square tube 6,6-2, hole 6-1, has flange on the 6-2, and in the inboard heterogenous metal brazing material soldering connection heat exchange sleeve 7 that adopts special use of flange, and heat exchange sleeve 7 stretches in the primary stainless steel runner square tube 6, and the condensation end of vacuum glass heat pipe 2 is inserted in the heat exchange sleeve 7.Described heat exchange sleeve 7 is a copper tube.Vacuum glass heat pipe 2 is installed on the collector bracket 1.
Primary stainless steel runner square tube 6 adopts special-purpose heterogenous metal brazing material soldering to connect with heat exchange sleeve 7.Can guarantee the sealing between primary stainless steel runner square tube 6 and the heat exchange sleeve 7, and bearing capacity.
Operation principle of the present utility model is as follows:
Vacuum glass heat pipe 2 absorbs solar energy and changes into heat energy, and the medium in the vacuum glass heat pipe is transferred to condensation end with heat, carries out heat exchange by the fluid media (medium) in red copper heat exchange sleeve 7 and the metal flow deferent 4, thereby realizes the Ji Hui of heat.
