A kind of solar thermal collector of new heat-exchange device
Technical field
Field of heat exchange is the utility model is related to, more particularly to a kind of solar thermal collector of new heat-exchange device.
Background technology
It is continuously improved as mankind's energy-consuming is horizontal, conventional fossil energy increasingly depleted, conventional fossil energy is adjoint
Pollutant emission problem cannot increasingly meet the needs of people are for future source of energy.Solar energy is used as one kind is inexhaustible to use it
Inexhaustible new cleaning fuel, just increasingly obtains the attention of people, for solar energy development increasingly obtaining into
Exhibition.Wherein solar power generation is a kind of advanced development and application to solar energy, it is finally turned solar energy by certain means
Electric energy is melted into, to meet the electricity needs of modern society.
At present, domestic and international high temperature solar evacuated collector tube uses the concentric straight tube structure of through type ectonexine more, and outer tube is
Vacuum tube, stainless steel pipe are metal tube (being used for the heat transfer medium that circulates), are evacuated between inner and outer pipes for reducing heat
It is lost in, the outer surface of hollow stainless steel pipe is also covered with coating for selective absorption.
Publication No. is that a kind of high-temperature heat-collection pipe of Chinese patent of CN106500365A and solar energy heat collector disclose gold
Belong to thermal-collecting tube assembly is internally formed the runner flowed to for the entirety of heat transfer medium circulation in U-typed, the runner
Inlet and outlet is respectively communicated with the heat transfer medium interface described in one.Heat collector disclosed in the program uses U-typed runner
To carry out heat exchange, so that occurring heat exchange medium in heat exchanging process.Due to the use of be unidirectional circulating direction,
So that the effect in heat exchange is bad, and it is inefficient, good heat exchange could not be formed, can cause some medium temperature
Degree is high, some temperature are low, and heat exchange is uneven.Therefore need to design a kind of heat exchanger effectiveness higher, more preferable heat exchange dress
Put.

Connect;Vacuum chamber is arranged between vacuum tube and thermal-collecting tube.
In such scheme, preferably outer to connect the cavity that insulating layer or vacuum are provided with the outside of header, insulating layer uses
Foamed material is made.
In such scheme, preferably medium inlet port is provided with sealing ring with insulation interlayer.
In such scheme, preferably vacuum tube is provided with vacuum tube sealing ring with insulation interlayer.
In such scheme, preferably the quantity of stainless steel pipe is 2-20.
In such scheme, preferably stainless steel pipe, thermal-collecting tube are identical with the quantity of vacuum tube.
In such scheme, the end of preferably vacuum tube is provided with tail conjunction, and the end of vacuum tube is nested in tail and closes.
The advantages of the utility model is with effect:
1st, the utility model is internally provided with interior even header by connect header outside, and the interior header both sides that connect are provided with
Stainless steel pipe, stainless steel pipe end are connected with thermal-collecting tube, so that medium connects header flowing from thermal-collecting tube inside, so that
So that formed it is gradual absorb heat so that preferably absorbing the heat on thermal-collecting tube so that heat exchange it is more efficient,
More preferably meets the needs of people are daily.
2nd, the utility model in setting by connecting header and stainless steel pipe, so that the flow direction of medium can determine
To from more preferable formation convection current.
3rd, the utility model has a variety of applications, for example pass according to the difference of the heat transfer medium heated in thermal-collecting tube
Thermal medium can be sky gas and water, conduction oil, fuse salt liquid etc., and the present apparatus can be applied to dryer, large-scale hot water work
Journey, photo-thermal power generation etc..
Brief description of the drawings
Fig. 1 is the utility model section schematic diagram.
Figure label:1 medium inlet port, 2 sealing rings, 3 insulating layers, 4 vacuum tube sealing rings, 5 corrugated pipe rings, 6 thermal-collecting tubes,
7 stainless steel pipes, 8 vacuum tubes, 9 tails close, connect header outside 10, connect header, 12 medium inlet and outlets in 11.
Embodiment
The utility model is described in further detail with reference to embodiments.
A kind of solar thermal collector of new heat-exchange device, as shown in Figure 1, including medium inlet port 1, sealing ring 2, protecting
Warm layer 3, vacuum tube sealing ring 4, corrugated pipe ring 5, thermal-collecting tube 6, stainless steel pipe 7, vacuum tube 8, tail close 9, outer even header 10, interior
Even header 11 and medium inlet and outlet 12.
Medium inlet port (1) is arranged on one end of interior even header 11, and 3 stainless steel pipes 7 are arranged on interior even 11 liang of header
Side and with it is interior even header 11 connect.Outer even header 10 is set in the outside of interior even header 11, and outer even 10 relative medium of header enters
1 other end of mouth is provided with media outlet 12.
Outer even 10 both sides of header are provided with thermal-collecting tube 6 and are connected with outer even header 10.Thermal-collecting tube 6 is set in stainless steel pipe
7 outside, stainless steel pipe 7 set opening to be connected with thermal-collecting tube 6, are arranged between stainless steel pipe 7 and thermal-collecting tube 6 by end
Cavity, the outside of thermal-collecting tube 6 scribble collection hot coating.Vacuum tube 8 is set in the outside of thermal-collecting tube 6 and by corrugated pipe ring 5 and collection
6 fixed seal connection of heat pipe, corrugated pipe ring 5 can be very good to prevent the influence of thermal boundary shrinkage, the sky of more preferable protection vacuum
Chamber enters air.Vacuum chamber is arranged between vacuum tube 8 and thermal-collecting tube 6.The outside of outer even header 10 is provided with insulating layer 3 or vacuum
Cavity, insulating layer 3 is made using foamed material.Insulating layer 3 primarily serves the effect of insulation, prevents the heat of medium to scatter and disappear,
