Abstract
The utility model relates to a heat preservation component, in particular to a solar energy utilizing apparatus which is a medium and high temperature resistance heat preservation pipe applicable for the solar energy heat utilizing apparatus. The utility model comprises a glass pipe combined by two layers, an inner layer and an outer layer, of glasses, a vacuum interlayer at the center of an outer pipe of the glasses, an inner wall of an inner pipe, a metal coating arranged on the inner wall of the inner pipe and a heat preservation flexible joint. The heat preservation performance of the utility model is better than various tube heat preservation components of various solar energy utilizing apparatuses. The utility model is particularly applicable for tube heat preservation of a medium and high temperature solar energy photothermal conversion utilizing apparatus at about 360 DEG C.
Description
The utility model relates to the heat preservation component that a kind of thermal technology of belonging to utilizes the field, definite a kind of insulating tube that is applied to solar energy optical-thermal conversion using equipment of saying so.
Existing pipe insulation parts, especially the heat preservation component that adopts of the pipe insulation in the solar thermal utilization equipment, normally by rock wool, perlite, the insulation pipe fitting that bipeltate or Foamex are made, in these insulation pipe fittings, though the suitable temperature range of the insulating tube that rock wool and perlite are made is bigger, resistance and high temperature resistance property is better, but heat insulation effect and water repelling property are poor, the heat windage is very big, for in megathermal solar power-generating facility, use these insulating tubes can cause a large amount of of heat to scatter and disappear, though and the insulation material heat insulation effect of being made by bipeltate and Foamex is a little better, but resistance to elevated temperatures is poor, can only use in the middle low temperature photo-thermal conversion using equipment below 200 degrees centigrade.
The purpose of this utility model provides a kind of good heat insulating exactly, and the pipe insulation pipe that is provided with of solar energy heat utilization that can anti-500 degrees centigrade of following temperature.It is characterized in that: be coated with layer of metal antiradiation film on the outer wall of the inwall of glass outer tube and glass inner tube, glass outer tube and glass inner tube are sealed from two ends, and the interlayer between the inner and outer pipes is pumped into vacuum layer; Be provided with the insulation flexible joint at the two ends of body; be provided with the stupefied and groove of convex annular at the two ends of flexible joint; centre at the insulation joint is provided with cushion pad, and the centre of cushion pad is a heat pipe through hole, is provided with the flexible protective lasso of protection aspirating hole sealing-in mouth at an end of outer tube.
Outstanding advantage of the present utility model is: heat-insulating property increases substantially, the diameter of insulating tube can reduce significantly, can bear the baking of the following middle high-temperature medium of 500 degree, be particularly suitable for using on the solar energy optical-thermal conversion facilities of high temperature in needs (about 400 degrees centigrade), as solar cooker, solar energy high temperature oven, solar boiler etc.
Below in conjunction with accompanying drawing the utility model is described in detail.
Accompanying drawing 1, canals of stilling structural representation of the present utility model.
The A-A profile of accompanying drawing 2, the utility model accompanying drawing 1.
The B-B profile of accompanying drawing 3, the utility model accompanying drawing 1
The partial enlarged drawing of the A-A profile of accompanying drawing 5, the utility model accompanying drawing 1.
The structural representation of accompanying drawing 5, the utility model insulation flexible joint.
In the accompanying drawing: 1 glass evacuated body, lasso, 101 glass outer tubes, 102. glass inner tube are 3. protected in 2. insulation flexible joint.Wherein being coated with the metal film 103 of anti-heat radiation at the outer surface of 101 inner surfaces of glass outer tube and glass inner tube 102, is vacuum heat-insulating layer 104 between interior outer glass pipe, is provided with bracing frame or supporting pad 105 between the interior outer glass pipe; It is stupefied 201 that insulation flexible joint 2 is provided with convex annular, and groove 202 and cushion pad 203 are a heat pipe through hole 204 in the centre of cushion pad, and insulation flexible joint 2 adopts the anti-aging preferably flexibly thermal insulation material of elasticity to make.In use, to pass through the through tube of heat pipe in the middle of the utility model glass inner tube 102, insulation flexible joint 2 is connected on the termination of canals of stilling 1, the annular prominent stupefied 201 of insulation flexible joint forms interference fit with glass outer tube 101, annular prominent stupefied 201 tightly card is being wrapped up in body 1, and pipe end played certain sealing function, the thermal loss that minimizing causes because of thermal convection current, heat pipe passes in the middle of the heat conduction through hole 204 of cushion pad 203 centres, cushion pad 203 is positioned at heat pipe the centre of glass inner tube through hole, avoid direct the contact with glass inner tube 102 inwalls, stop the heat conduction, when the length of heat pipe is big, then can be as required, at the other end of insulation flexible joint 2, canals of stilling 1 of the present utility model of clamping again, so just can be according to needed length, canals of stilling 1 and insulation flexible joint 2 is alternately subsequent.Be located at protection lasso 3 on the glass evacuated body 1 for to make such as silicon rubber, can protect the exhaust outlet envelope mouth on the glass outer tube 102 not broken by anti-aging elastomeric material.When heat energy conducts by the medium in the heat pipe, the vacuum heat-insulating layer 104 of this insulating tube body 1 can stop the path of heat conduction and thermal convection current effectively, insulation flexible joint 2 can be with the gap sealing between per two bodys, the convection current of also effectively having blocked inner air tube, the metal coating 103 on the canals of stilling interlayer wall can stop heat radiation effectively.
