CN101699191A discloses a kind of composite surface concentrating vacuum tube thermal-arrest integrally packaged type solar heat collector, by
Composite surface condenser, vacuum tube collector, adjustable tracker and package casing etc. form.Sunlight enters through clear glass cover plate
After injecting composite surface condenser, it is collected on vacuum tube collector through the reflection of its inner surface, absorbs through vacuum tube collector
Produce high temperature heat, this heat energy is conveyed to user through conduction by the heat-conducting work medium in vacuum tube collector again.
The type of current solar thermal collector has flat-plate solar heat collector, glass vacuum pipe heat collector, U-tube
Formula vacuum tube collector, heat pipe vacuum tube hot collector and five kinds of single flow vacuum tube collector.Every kind of heat collector has necessarily
Advantage, there is also clearly disadvantageous：
1) flat-plate solar heat collector pressure-bearing, less scaling, but the loss of heat-absorbent surface heat loss through convection is big, thermal efficiency ratio relatively
Low；
2) the glass vacuum pipe heat collector thermal efficiency is high, but is unable to bearing operation, easy bursting by freezing, and easy fouling is not suitable for
In large-area solar water heating system.Multiplex make family's solar water heater heat-collecting part.
3) U-tube formula vacuum tube collector pressure-bearing, less scaling, but fluid is easily short-circuit.Additionally, heat-absorbent surface mostly is flat
Face, heat absorption surface sunlight absorption efficiency is not high.
4) heat pipe vacuum tube hot collector pressure-bearing, less scaling, thermal efficiency ratio is higher, but price comparison is expensive, heat pipe
Can easily decay aging.
5) single flow vacuum tube collector pressure-bearing, less scaling, thermal efficiency ratio is higher, but heat absorption surface sunlight absorbs effect
Rate is not high.
For the thermal efficiency is high, easy fouling or the deficiency such as cost is higher, the utility model proposes a kind of heat-absorbent surface is too
Sunlight absorption efficiency height, pressure-bearing, the straight ribbed pipe of interpolation three fin that is difficult structure, can be used in solar energy in large area hot-water heating system are true
Blank pipe heat collector scheme.Popularization for vacuum tube solar heating element and engineer applied provide technical support.

Specific embodiment
Describe in detail by the following examples or description this utility model, rather than this utility model is limited.
Embodiment 1：
The straight ribbed pipe vacuum tube collector of a kind of interpolation three fin as shown in Figure 1, including glass evacuated sleeve pipe, described glass
In vacuum sleeve, center is provided with straight ribbed pipe；The two ends of glass evacuated sleeve pipe are provided with sealing ring, and the two ends of straight ribbed pipe pass through close
Seal is simultaneously fixed by sealing ring；Straight ribbed pipe is provided with three fins；Article three, fin angle between any two is 120 °, wherein one
Fin is straight up.Described straight ribbed pipe is made up of red copper or aluminum.One end of straight ribbed pipe is fluid intake, and the other end goes out for fluid
Mouthful.The thickness of described fin is 2～3mm, highly 20～30mm, the length 80～120mm shorter than vacuum glass of fin.Described straight
Ribbed pipe and fin are provided with spectrum selected coating, improve sun efficiency of light absorption, reduce the infra-red radiation radiation loss of itself.For
Improve solar energy thermal conversion efficiency, improve the thermal efficiency of heat collector.
Fin distribution as shown in Figure 2, fin 1 is arranged in a vertical direction, and fin 2 is located at left side, fin 3 is located at right side.
When the sun is in right lateral aspect, fin 1 and 3 absorbs sunlight, is transformed into thermal source, and heating flows through the fluid in pipe.Work as the sun
When being in left side orientation, fin 1 and 2 absorbs sunlight, is transformed into thermal source, and heating flows through the fluid in pipe.In the sun is in
Between orientation when, fin 1, fin 2 and fin 3 absorb the sun simultaneously, become thermal source heating flow through in pipe fluid.
Internal and external layers of glass forms glass bushing, middle evacuation, eliminates the heat loss through convection loss of heat absorbing fins.As Fig. 3 institute
Show, straight for three fins ribbed pipe is formed closed cavity with inner layer glass space by sealing ring, prevent the air of closed cavity from absorbing fin
Tubular heat, and it is lost to surrounding, reduce the heat-absorbent surface thermal efficiency.Sealing ring also functions to support and fix the work of straight ribbed pipe simultaneously
With.
As shown in figure 4, China is located at the Northern Hemisphere, solar thermal collector is arranged generally towards due south, the inclination angle with horizontal plane
For 20 ° about.Because sun east goes out the kinetic characteristic that west falls, relatively low with the sun altitude ratio in afternoon in the morning, now plane
Two fins straight ribbed pipe cosine effect is big, and the effective endotherm area of sunlight of absorber plate is little, and the thermal efficiency of system is low, as Fig. 4 (a) institute
Show (only draw sunrise sun altitude smaller when situation, sunset situation be similar to).Under the conditions of same vacuum glass caliber,
According to the straight ribbed pipe of three fins, regardless of sun altitude, the cosine effect of heat-absorbent surface is all weaker, contrasts Fig. 4 (a) and figure
The effective absorbing surface of 4 (b) sunlight can be seen that the effective absorbing surface area of three fins straight ribbed pipe sunlight greatly, and the thermal efficiency is high, such as schemes
Shown in 4 (b) (only draw sunrise sun altitude smaller when situation, sunset situation is similar to).
