Abstract
A glass diameter-unequal vacuum tube with hollow tube in inner tube dedicated for solar water heater comprises an inner tube and an outer tube. An interlayer that is vacuumized is formed between the inner tube and the outer tube, and an elastic bracket and getter are positioned at the tail interlayer of the vacuum tube. The vacuum tube also includes a hollow tube whose outer diameter is less than the inner diameter of the inner tube with two ends close, and two brackets are used to fix the two ends of the hollow tube with the inner tube separately. The hollow tube of the utility model which reduces the amount of heat carrier of the heat absorption inner tube is good to improve the thermal efficiency by reducing self thermal capacity. Addition more, providing the elastic bracket into the vacuum heat insulation tube, which improves the thermal efficiency of the vacuum tube by reducing the heat loss which is induced by elastic bracket greatly.

To achieve these goals, the utility model has adopted following technical scheme: solar water heater's special glass Reducer Tube of pipe racks hollow pipe in a kind of, pipe and outer tube in comprising, form interlayer between the inner and outer pipes and be evacuated, in the afterbody interlayer of vacuum tube, be provided with elastic support and getter, be characterized in, also comprise hollow pipe, this hollow pipe is the sealed tube of a closed at both ends, its external diameter is isolated fixing respectively less than the internal diameter and unsettled being arranged in the interior pipe of interior pipe by two elastic supports between the two ends of hollow pipe and the interior pipe.
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, the pipe afterbody has a undergauge section in described, and the described elastic support that is arranged in the vacuum tube afterbody interlayer is stuck between the undergauge section of glass isolated tube and interior pipe afterbody.
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, and the elastic support in the described afterbody interlayer that is arranged on vacuum tube is stuck between heat insulation pedestal and the outer tube.
Described solar water heater's special glass Reducer Tube is the reduced pipe of front end band undergauge.
Solar water heater's special glass Reducer Tube of pipe racks hollow pipe in the utility model is owing to installed hollow pipe additional in pipe, can make the minimizing of the heat carrier quantity in the pipe in the antisolar glass, reduce himself thermal capacity, help improving efficiency of utilization, have good frost resistance; 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 mouth of pipe 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.
