Evacuated collector tube is one kind of the evacuated collector tube of glass-metal sealing.At present, the heat pipe with tablet fin is encapsulated in list
In the vacuum tube of layer glass, using freeze proof copper (Water Heat Pipes as efficient heat transfer element, the sealing-in between glass-metal
Using advanced hot-press sealing technology.
Chinese patent literature discloses one kind《Utilize the heat pipe of solar energy evacuated optically focused》, the patent No.
201310741150.3, content is to include the collecting end of heat and release end of heat of heat pipe, and collecting end of heat includes concentration inverse light panel and one end
The outer tube and central tube of opening, refrigerant are placed in the central tube of sealing, and outer tube is glass tube, and outer tube openend, which is equipped with, axially to be become
The metal end of shape, the inside of outer tube is vacuum-sealed cavity, and central tube is set with the outer coaxial tube heart, and vacuum sealing is stretched out in one end
Chamber, the central tube of vacuum sealing intracavitary are the heat absorbing end of heat pipe, and one section of central tube outside vacuum-sealed cavity is release end of heat, central tube
Release end of heat be placed in the medium of thermal conductive pipe；Concentration inverse light panel is located in vacuum-sealed cavity, the focus point position of concentration inverse light panel
In the central axes of central tube heat absorbing end.
Find that this heat pipe using solar energy evacuated optically focused has the following problems in use：First, heat transfer medium is located at one
In the central tube of a straight barrel type, although cooling-vaporization Xun Huan is fast, heat transfer medium heated time during cycling is short；
Second is that the concentration inverse light panel being connected on central tube is straight-plate-type, heating surface area is small, it is impossible to make full use of all glass vacuum heat collecting
Vacuum volume in pipe.
The content of the invention
The object of the present invention is to provide a kind of heat transfer medium heat absorption the time it is long, the concentration inverse light panel heating surface area in vacuum tube
Greatly, the high middle temperature solar energy heat collection pipe of the thermal efficiency.
The purpose of the present invention is what is be achieved through the following technical solutions, temperature solar energy heat collection pipe includes outer tube, is located in this
Central tube in outer tube, the absorber plate being connected in the shape of a spiral with central tube are also connected in the shape of a spiral on the opposite side of absorber plate
One peripheral tubes, and central tube is communicated with peripheral tubes, i.e. the bottom of one central tube of peripheral tubes one end is connected, peripheral tubes it is another
One end is connected in central tube at metal end with central tube, and heat transfer medium, the inside of outer tube are equipped in central tube and peripheral tubes
For vacuum-sealed cavity, central tube is set with the outer coaxial tube heart, and vacuum-sealed cavity, the central tube of vacuum sealing intracavitary are stretched out in one end
For the heat absorbing end of heat pipe, one section of central tube outside vacuum-sealed cavity is heat release colling end.
Preferably, outer tube is glass tube, the closing of outer tube one end, another end opening, openend be equipped with can axial deformation gold
Belong to end cap.
Preferably, when central tube the stretches out vacuum-sealed cavity and engaging portion of metal end passes through welded seal.
Preferably, absorber plate is made of copper material.
Further to verify the collecting efficiency of the thermal-collecting tube of thermal-collecting tube of the present invention and the prior art, inventor does
It tests below：
Single tube is tested：By the gravity thermal-collecting tube of same size（Nanjing Cheng Yuan Solar Co., Ltd produces）With it is of the present invention
Thermal-collecting tube is placed in 60 DEG C of light simulation heating casees.Cooling section is placed in 11.k3g attemperaters, and heat pipe inclination angle is 40.Test table
Bright, the average heating rate per hour of the latter is 6 DEG C, and the former only has 2 DEG C.
A water heater is assembled into 16 thermal-collecting tubes of the present invention, heat collector size is
180cmxI20cmxl5cm, effective daylighting area is l.8m2, tank size 130cmx55cmx25cm, water capacity 70kg.Test
As a result:The water heater winter average daily efficiency is higher than 35%, and April, average daily efficiency was higher than 50%.
The advantage of the invention is that：It is compared with straight-plate-type absorber plate, firstly, since absorber plate connects in the shape of a spiral with central tube
It connects, increases light endotherm area of the absorber plate in vacuum sealing intracavitary, secondly, and since absorber plate is compared with central tube axis
It arranges in the shape of a spiral, no matter how how solar rays angle changes in one day, has the most preferably corresponding position of absorber plate, with more preferable
Receive light.3rd, due to adding peripheral tubes on spiral helicine absorber plate, the heat that absorber plate absorbs is in
The heat transfer of heart pipe can also add heat-transfer path and improve heat transfer by the heat transfer of peripheral tubes
Speed.
Due to using the above structure, significantly improving the thermal efficiency, thus solar water heater made of thermal-collecting tube starts
Soon, good heat-transfer, central tube and periphery intraductal working medium are few, start soon, remain able to produce in the case where weather is rain or shine changeable
Heat water.Also there is the thermal diode performance unidirectionally conducted heat, can prevent the heat at night and cloudy day from flowing backwards.Antifreeze ability is strong,
It is suitble to use in extremely frigid zones.
