Background technology

Present solar water heater, mostly be that the thermal-arrest part partly is separated with heat accumulation, it has, and the thermal efficiency is low, the water temperature gradient big, use uncomfortable shortcoming, and adopts traditional all-glass vacuum thermal-collecting tube to have the shortcoming that water can't be discharged as the incrusted deposit of medium appearance.February nineteen ninety, the Chinese patent 89208809.5 of Granted publication on the 7th disclosed a kind of club-type passive solarenergy water heater, the upper end of its heat collection water storage case is an orthodrome, and the lower end is little circular arc, and the left and right sides is the plane, vertical section forms a club-type structure, is furnished with diaphragm plate in the water tank; In August, 1993, the Chinese patent 92235560.6 of Granted publication on the 25th disclosed a kind of club-type passive solarenergy water heater, it overcomes in original club-type passive solarenergy water heater casing dividing plate and tee T aqueduct is set, it has the shell of band transparent cover plate, heat-insulation layer is installed in the shell, a heat collection water storage case is installed in the heat-insulation layer, the similar inverted rod hammer of its vertical section, one upper lateral part of heat collection water storage case has an exhaustion spill mouth, and opposite side has and can be used as into or the mouth of a river of water outlet; Above club-type solar water heater all has the bearing capacity that improves water tank, the advantage of the comfort when suppressing formed water temperature gradient in the solar energy heating process and improving water; In June, 2000, the Chinese patent 99221421.1 of Granted publication on the 7th disclosed the two vacuum solar collector tubes of a kind of full glass, it comprises glass outer tube and glass inner tube, glass outer tube ring-type sealed knot is on the outer wall of glass inner tube, glass inner tube is than the outer pipe range of glass, have the last cold water time freely make things convenient for, vacuum tube does not burst, thermal-collecting tube non-scaling, installation and maintenance are convenient, the advantage of good, the interior pipe long service life of thermal-collecting tube interchangeability.

Summary of the invention

The utility model provides a kind of club-type duplex tube solar water heater, and it has solved the heat storage water tank sealing and heat-insulating property is bad, the hot water radiation loss big, the heat-exchange end outer surface adheres to incrustation scale and causes the problem that the heat-exchange end heat exchange property is bad and service life is short in the heat transfer process.

The technical scheme that the utility model adopted is as follows:

A kind of club-type duplex tube solar water heater, comprise shell 2, outer end socket 3, heat-insulation layer 4, condensation or heat-exchange end 5, club-type heat storage water tank 6, exhaust and overflow pipe 7, go up water and water pipe 8, interior vacuum tube 9 and outer vacuum tube 10, duplex tube 11, sealing ring 12, tail carriage 13 and support 14, it is characterized in that: adopt up big and down small non-orbicular club-type structure to do heat storage water tank 6, adopt the two vacuum heat collection pipes 11 of full glass to do solar thermal collector, duplex tube 11 inserts in the sealing ring 12 of club-type heat storage water tank 6, and its pipe tail is put into tail carriage 13.

Described club-type duplex tube solar water heater, the condensation or the heat-exchange end 5 of the two vacuum heat collection pipes 11 of full glass adopt the heat treatment of macromolecule thermal-conducting coating.

Like this under effect of sunlight, the low boiling superconductive medium in the thermal-collecting tube is evaporated to condensation end, carries out heat exchange with water in the case, after water in the case is heated, under the effect of " density contrast ", constantly microcirculation, make that water temperature continues to raise club-type heat storage water tank Totally enclosed heat-preserving; Superconducting fluid in two vacuum solar collector tubes, get back at the bottom of the thermal-collecting tube during no sunlight, institute's heat accumulation water can not pass through the reverse heat radiation of duplex tube in the case, even in high and cold severe winter, hot water radiation loss in the heat storage water tank is also minimum, and having guaranteed provides productions as usual, lives and use hot water in the winter of severe cold the weather of the sun being arranged.

Club-type duplex tube solar water heater of the present utility model, its technology with club-type solar water heater and the two vacuum solar collector tubes of full glass combines, this club-type duplex tube solar water heater had both had the bearing capacity that improves water tank, the advantage of the comfort when suppressing formed water temperature gradient in the solar energy heating process and improving water, having the last cold water time again simultaneously freely makes things convenient for, vacuum tube does not burst, the thermal-collecting tube non-scaling, installation and maintenance are convenient, thermal-collecting tube interchangeability is good, the advantage of interior pipe long service life, it is widely used in production, life hot water.
