Abstract
The utility model provides a metal core type solar thermal collector. A metal inner pipe is installed in a glass outer pipe in an inserted mode, wherein the metal inner pipe is coated with a solar heat absorption layer. One end of the metal inner pipe is fixedly bonded with a metal heat conduction head and extends out of a pipe orifice of the glass outer pipe. A kovar alloy sleeve is movably installed on the metal heat conduction head in a sleeved mode, a heatproof sealant is connected between the kovar alloy sleeve and the metal heat conduction head in a sealing mode, the edge of the kovar alloy sleeve and the pipe orifice of the glass outer pipe are connected in a sealed mode, and an interlayer between the metal inner pipe and the glass outer pipe is vacuumized. Sunlight penetrates through the glass outer pipe and radiates the heat absorption layer on the outer surface of the metal inner pipe to heat the metal inner pipe directly, the vacuum interlayer is used for heat preservation, and heat of the metal inner pipe is conducted outwards through the metal heat conduction head for heating water. The metal core type solar thermal collector is low in thermal resistance, quick in heat transmission, and high in efficiency; water does not flow through the interior of pipes, and pipe explosions are prevented.
Description
Technical field
The utility model relates to a kind of solar thermal collector, particularly relates to a kind of metal-cored formula solar thermal collector.
Background technology
The vacuum heat collection pipe of now widely used solar water heater, the outer wall of its inner tube scribbles solar energy heat absorbing layer, heat absorption is conducted to the water body in pipe by inner tubal wall, because tube wall is glass, therefore its thermal resistance is very large, the heat exchange of thermal-collecting tube to water body in storage tank, only depend on the rising after water body expanded by heating in thermal-collecting tube, efficiency is lower, in addition, in glass tube, leak water, antifreeze also poor.Though have minority with metal tube, to do the solar thermal collector of inner bag at present, because of its metal and glass sealing scheme improper, the bad sealing structure that leaks gas, has of sealed portion bit loss is too numerous and diverse, cost is high for easily causing of having, and fails extensive use.By extensive retrieval, not yet find the technical scheme relevant with the utility model.
Utility model content
The purpose of this utility model is exactly the defect causing in order to overcome existing solar thermal collector unreasonable structure, and a kind of metal-cored formula solar thermal collector providing.
The utility model solves the technical scheme that its technical problem adopts: a kind of metal-cored formula solar thermal collector, comprise metal inner pipe and glass outer tube, one end opening of glass outer tube, other end sealing, the border seal of metal inner pipe, appearance scribbles solar energy heat absorbing layer, its one end is provided with metal heat-conducting head, metal inner pipe is plugged in glass outer tube, metal heat-conducting head stretches out the mouth of pipe of glass outer tube, it is characterized in that: the suit one kovar alloy cover of activity on metal heat-conducting head, between metal heat-conducting head and kovar alloy cover, be sealed with temperature resistant encapsulation glue, the edge of kovar alloy cover and the mouth of pipe sealing-in of glass outer tube, interlayer between metal inner pipe and glass outer tube is evacuated.
The beneficial effects of the utility model are: daylight, through glass outer tube, irradiates the direct heating of metal inner tube of heat-sink shell of metal inner pipe outer surface, by vacuum interlayer, is incubated, and the heat of metal inner pipe conducts out through metal heat-conducting head, heating water body.Because metal thermal resistance is little, therefore that it conducts heat is fast, efficiency is high, and in pipe, do not leak water, anti-bombing.The kovar alloy cover adopting, the coefficient of expansion and glass are close, can prevent the destruction of cold and hot stress to glass-to-metal seal position, kovar alloy cover and metal heat-conducting head movable set, between sealing-in temperature resistant encapsulation glue, because fluid sealant has elasticity, can effective compensation metal heat-conducting head expand with heat and contract with cold, and keeps sealing.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Accompanying drawing explanation:
Fig. 1 is the front view of the utility model embodiment;
The specific embodiment
As shown in Figure 1, a kind of metal-cored formula solar thermal collector, the border seal of its metal inner pipe 1, appearance scribbles solar energy heat absorbing layer, its one end is provided with metal heat-conducting head 2, one end opening of glass outer tube 3, other end sealing, metal inner pipe is plugged in glass outer tube, metal heat-conducting head stretches out the mouth of pipe of glass outer tube, and suit one kovar alloy movable on metal heat-conducting head overlaps 4, is sealed with temperature resistant encapsulation glue 5 between the two, the edge of kovar alloy cover and the mouth of pipe sealing-in of glass outer tube, the interlayer between metal inner pipe and glass outer tube is evacuated.Daylight, through glass outer tube, irradiates the direct heating of metal inner tube of heat-sink shell of metal inner pipe outer surface, by vacuum interlayer, is incubated, and the heat of metal inner pipe conducts out through metal heat-conducting head, heating water body.
