Power element；8. can cut down seal connector；9. cover glass tube；10. necking segment；The cover glass tube of 11. indents.
In Fig. 1, with the absorber 2 being placed in vacuum heat-insulating layer 1, one is made up of ascending tube 3, down pipe 4 and release end of heat 5
Natural Circulation runner, and one be connected with down pipe 4 low thermal resistance, with free end pawl 6 bimetal leaf heating power element 7 and
One can be cut down seal connector 8 and form one and can cut down sealing-in overheating protective vacuum circulation heat collection element, inside Natural Circulation runner
Fill but be not filled with liquid heating agent, the ascending tube 3 of Natural Circulation runner and absorber 2 one system being placed in vacuum heat-insulating layer 1
Make.Seal connector 8 can be cut down and be tightly connected tubulose release end of heat 5 and the cover glass tube 9 of Natural Circulation runner, form one and use true
Idle loop heat collecting element.Material can be cut down can either be connected with glass heat press seal again with metal solder.
Fig. 1 embodiment embedded vacuum circulating heat-collecting component makees the inclination installation that release end of heat 5 height is put in the sun, makes oblique void
Heating agent liquid level shown in line is the level of state.Sunlight is converted to heat energy through cover glass tube 9 on absorber 2, and heat energy is through absorbing
Body 2 is passed to the heating agent in ascending tube 3 and makes heating agent expanded by heating be floated by ascending tube 3, and the tubulose at Natural Circulation runner is put
At hot junction 5, heating agent is released heat generating temperature and is reduced to sink to entering down pipe 4, is again introduced into ascending tube 3 heated also after sinking to the end
Float.So go round and begin again circulation thermal-arrest along approach shown in band arrow curve.
Under normal working temperature, by tubulose release end of heat 5 heat release, the free end pawl 6 of bimetal leaf heating power element 7 not with cover
Glass tubing 9 contacts.
When heat collecting element air drying internal temperature is too high, the free end pawl 6 of bimetal leaf heating power element 7 turns to void outside being heated
Position shown in line contacts with cover glass tube 9, and partial heat energy is dispersed into environment by these free end pawls 6 and cover glass tube 9, makes collection
The temperature reduction of thermal element realizes overtemperature protection.Can automatically terminate after overtemperature protection.
Heating power element 7 also can be connected with absorber 2 low thermal resistance；Memorial alloy also can be used to manufacture heating power element.
Answering degasification before Natural Circulation runner fill heating agent, fill is complete should be closed.The design of Natural Circulation runner and
Selection and the fill amount thereof of heating agent should meet: the 1) foundation of Natural Circulation；2) heating agent stable performance is not easy thermal decomposition, saturated steaming
Vapour pressure is low, not with Natural Circulation runner generation chemical reaction；3) possessing heating agent expansion space in Natural Circulation runner makes heating agent coagulate
Gu or relevant parts are not produced adverse effect during air drying volumetric expansion；4) release end of heat operating mode is good.
In Fig. 1, use ascending tube 1 to stretch into the design within tubulose release end of heat 3, be favorably improved collecting efficiency.
Vacuum heat-insulation between ascending tube 1 and the down pipe 2 of Fig. 1 embodiment, highly beneficial to circulation thermal-arrest.
The release end of heat 3 of Fig. 1 embodiment is that tubulose is outwardly directed.Vacuum circulating heat-collecting element also can use the heat release of indent
End or heat release end face.
In cover glass tube non-light area, inner surface coats infrared reflective material, is effectively reduced the radiant heat of heat collecting element
Damage.
In Fig. 2, with the absorber 2 being placed in vacuum heat-insulating layer 1, one is made up of ascending tube 3, down pipe 4 and release end of heat 5
Natural Circulation runner, and one be connected with down pipe 4 low thermal resistance, with free end pawl 6 bimetal leaf heating power element 7 and
The cover glass tube 9 of one Guan Bi forms a cover glass tube heat release overheating protective vacuum circulation heat collection element, Natural Circulation runner
Internal fill but be not filled with liquid heating agent, the ascending tube 3 of Natural Circulation runner and the absorber 2 one being placed in vacuum heat-insulating layer 1
System is made.It is lined with a resilient heat transfer between tubulose release end of heat 5 and cover glass tube 9 necking segment 10 of Guan Bi of Natural Circulation runner
Part is to improve heat transfer.During normal thermal-arrest, tubulose release end of heat 5 is by resilient heat transfer part and necking segment 10 heat release.
Can be omitted by cover glass tube and necking segment heat release thereof and can cut down seal connector, good airproof performance, corrosion-resistant.
Sometimes, the load container coordinated with heat collecting element is also required to heat collecting element such a necking segment.
In Fig. 3, with the absorber 2 being placed in vacuum heat-insulating layer 1, one by ascending tube 3, down pipe 4 and coil heat exchanger
The Natural Circulation runner that release end of heat 5 is constituted, and one be connected with down pipe 4 low thermal resistance, with the bimetal leaf of free end pawl 6
The cover glass tube 9 of the Guan Bi of heating power element 7 and a band concave section 11 forms an indent release interfaces overtemperature protection vacuum and follows
Ring heat collecting element, the internal fill of Natural Circulation runner but be not filled with liquid heating agent, the ascending tube 3 of Natural Circulation runner be placed in true
Absorber 2 integral production in empty thermal insulation layer 1.It is lined with one between coil heat exchanger release end of heat 5 and cover glass tube 9 concave section 11
Resilient heat transfer part is to improve heat transfer.During normal thermal-arrest, coil heat exchanger release end of heat 5 is by resilient heat transfer part and cover glass tube 9
Concave segment 11 heat release.
The coil heat exchanger release end of heat 3 coordinated with cover glass tube concave section 11 in Fig. 3 embodiment can also use other shapes
