Also comprise the glass isolated tube, this glass isolated tube is the glass short tube that one one end seals an end opening, its integral body is arranged in the afterbody interlayer of vacuum tube, described elastic support is two, between pipe afterbody and the glass isolated tube, another was stuck between glass isolated tube and the outer tube in one of them was stuck in.
Also comprise the glass isolated tube, this glass isolated tube is the glass short tube that one one end seals an end opening, a glass isolated tube part is arranged in the afterbody interlayer of vacuum tube, it is protruding and link to each other with the outer tube frit seal passing the place that a part is passed outer tube, described jump ring is one, manages between afterbody and the glass isolated tube in it is stuck in.
Also comprise heat insulation pedestal, this heat insulation pedestal is the glass short tube that one one end seals an end opening, it is arranged in the afterbody interlayer of vacuum tube, the blind end of heat insulation pedestal links to each other with the local welding of the tail end of interior pipe, the openend of heat insulation pedestal is towards the tail end of outer tube, described elastic support is one, and this elastic support is stuck between outer tube and the heat insulation pedestal.
Described Special Glass Vacuum Tube for Solar Water Heater is the reduced pipe of front end band undergauge.
The Special Glass Vacuum Tube for Solar Water Heater of the half of band of the interior pipe of the utility model semicircle metal wing heat absorbing sheet is owing to having installed semicircle metal wing heat absorbing sheet additional and it is wrapped on inner pipe in pipe, no glass and metal be sealing problem mutually, because of the diameter of pipe in the antisolar glass little, the inside pipe wall gross area is little, the tension that inner pipe wall bears during high temperature is little, requirement of strength to material is low, thereby has reduced material cost and safety coefficient is big; Built-in elastic support is installed in the cavity with vacuum insulation, makes the heat loss that causes by elastic support reduce greatly, thereby the thermal efficiency of vacuum tube is improved; In addition, adopt inner spout undergauge technology, make vacuum tube realize solid matter on water heater, the gap between the adjacent vacuum tube reduces, and makes the overall efficiency of water heater obtain increasing substantially.The above technology of comprehensive employing, the complete machine thermal efficiency of the present utility model can reach 73%, is in world lead level.
