Abstract
The utility model relates to the glass vacuum tube of a solar copper heat-transferring tube. The copper heat-transferring tube is welded with a heat-transferring sheet made up of stannum-copper alloy, and is arranged in a glass tube. The bottom of the heat-transferring tube supports the upper end by a metal sheet. The copper heat-transferring tube is extended out of the center hole of a sealing cove, and the sealing cover and the glass tube are sealed by glass cement. The sealing cover is provided with an air pumping hole, and the air pumping hole is sealed by heat-resisting glue after the glass tube is pumped into the vacuum. The interior of the glass tube forms a vacuum space without any mediums, and the heat can not be transferred to the outside. The heat-transferring sheet made up of stannum-copper alloy transfers the heat. The utility model has the advantages of simple manufacturing technique, low cost, and high efficiency.
Description
The utility model relates to a kind of glass-vacuum tube of solar energy copper heat pipe, belongs to the technical field of solar energy equipment.
Two kinds of solar energy glass vacuum pipes are arranged in the market, its strong point and weak point are respectively arranged, its concomitant shortcoming is that the equipment of making vacuum tube needs huge investment, and process also more complicated is loaded down with trivial details, wherein as the glass tube of certain university's production can only accumulation of heat, can not heat conduction, though and another kind of glass-vacuum tube heat conduction is excessive, dislike heavy slightly, and the equipment investment of making is also bigger than normal, makes cost up.
The purpose of this utility model is the glass-vacuum tube that a kind of solar energy copper heat pipe will be provided, it can overcome above-mentioned shortcoming, its heat conduction heat absorption partly uses tin or gun-metal to make absorber plate, spray black, the heat-absorbing paint of heat absorption more onboard, this just changes original two kinds of vacuum tubes need use shallow jet device of large-scale electromagnetism and the shallow process of penetrating of plumbous nitrogen al deposition, makes simplified manufacturing process, and cost is showing and reduces, because tin or gun-metal conduct heat fast, heat transfer efficiency is improved.
Capping has flange, and it is comparatively good to seal sealing effectiveness with glass cement between the glass tube.
The purpose of this utility model is achieved in that
The pressure welding of tin copper conducting strip is on the copper heat pipe, and spraying heat-absorbing paint, be inserted in the glass-vacuum tube, this glass-vacuum tube one is held level with both hands together, other end sealing is circular-arc, supports the copper heat pipe with sheet metal in the pipe, the capping cross section is a Jiong shape, central authorities are porose, and all levels are extended a flange to a side, and capping places on the glass-vacuum tube, making the copper heat pipe pass the hole stretches out in outside the capping, seal with heat-resistant adhesive between hole and heat pipe, seal with glass cement between capping flange and glass tube, the tube sealing end face has aspirating hole, seal with heat-resistant adhesive after bleeding, between copper heat pipe and the glass tube vacuum space is arranged.
Fig. 1 is the vacuum tube schematic diagram of solar energy glass copper heat pipe.
Fig. 2 is the A-A cutaway view of Fig. 1.
Now in conjunction with the accompanying drawings the structure of the glass-vacuum tube of solar energy copper heat pipe is described in detail.
By Fig. 1,2, tin copper heat absorption conductive sheet (2) pressure welding is on copper heat pipe (1), the spraying heat-absorbing paint, be inserted in the high strength glass vacuum tube (4), this glass-vacuum tube (4) one is held level with both hands whole, other end sealing, and be circular-arc, copper heat pipe (5) is fixing with sheet metal (3) supporting, nylon cover (3) cross section is a JiongZi Xing, middle position porose (10), when capping (3) is contained in the glass-vacuum tube upper end, make copper heat pipe (1) can pass the hole (10) of capping (3), can stretch out in capping (3) outside, between the hole of nylon cover (3) and heat pipe, seal with heat-resistant adhesive (6), between the flange (11) of glass tube (4) and capping (3), also use glass cement (7) to seal, capping (3) end face has an aspirating hole (9), after adopting dress heat pipe (1) and capping (3), fill out half heat-resistant adhesive earlier being evacuated in the glass tube (4), and then all shut, after solar radiation, owing between glass tube (4) and the heat pipe (1) vacuum space (8) is arranged, do not have heat-conducting medium therebetween, make the heat of absorption can not lead back extraneous, can only give copper heat pipe (1) by tin copper conducting strip (2) heat conduction of absorber plate, conduct heat by it again and give the medium that needs heating.
Compared with prior art, solar energy glass copper heat pipe vacuum tube has following advantages:
1, conducting strip adopts tin or gun-metal, and heat conduction is rapid, and technology is simple, makes Cost need not use the shallow technology of penetrating of electromagnetism.
2. the Jiong tee section is adopted in capping, between its flange and the glass tube with glass tube it Between with glass cement sealing, sealing effectiveness is good.
3. glass tube is vacuum, is again a vacuum layer between glass and the heat pipe, shape Become the characteristics of two-layer vacuum, heat transfer efficiency is more effective.
Claims (1)
1. the glass-vacuum tube of a solar energy copper heat pipe, it is characterized in that: tin copper conducting strip (2) pressure welding is on copper heat pipe (1), and spraying heat-absorbing paint, be inserted in the glass-vacuum tube (4), this glass-vacuum tube one is held level with both hands together, other end sealing, be circular-arc, support copper heat pipe (5) with sheet metal (3) in the pipe, capping (3) cross section is a Jiong shape, central authorities porose (10), all levels are extended a flange (11) to a side, capping (3) places on the glass-vacuum tube (4), makes copper heat pipe (1) pass hole (10) and stretches out in outside the capping (3), seals with heat-resistant adhesive (6) between hole (10) and heat pipe (1), between capping (3) flange (11) and glass tube (4), seal with glass cement (7), tube sealing (3) end face has aspirating hole (9), and seal with heat-resistant adhesive the back of bleeding, and between copper heat pipe (1) and the glass tube (4) vacuum space (8) is arranged.
