Technical field
The present invention relates to a kind of light-operated hot rectifiers.
Background technique
Hot rectifier has the similar characteristic of semiconductor diode, can control the size of hot-fluid, transmits different heat letters
Number.The wide, strong anti-interference characteristic with suitable material.The method control that hot rectifier can be designed by element doping, geometry
Heat the size of flow.The development of current hot rectifier predominantly stays in the layer for changing heat transfer medium material composition and cross sectional shape
On face.Since heat transfer medium and structure are constant in use for hot rectifier, hot rectification efficiency then immobilizes.To heat
The regulation of flow cannot obtain real-time control, greatly limit the application range and market value of hot rectifier.
Summary of the invention
In view of the problems of prior art, the invention discloses a kind of light-operated hot rectifier and heat rectification is improved
The method of the hot rectification efficiency of device, disclosed technical solution is the cross sectional shape for changing nano wire with light flex effect, to change
Variable resistance controls light flex effect by adjusting ultraviolet ray intensity, realizes the control to hot-fluid.Specifically, the present invention is
It is achieved through the following technical solutions:
A kind of hot rectifier, upper substrate, lower substrate, nano wire, baffle, side opening plate, optical plug, fiber channel.ZnO
Nano wire is directly prepared on the lower substrate of SiO2 material by chemical vapour deposition technique, and nano wire and substrate use C9H16Pt
Deposition connection.Side opening plate is mainly used for installing optical plug, and introducing wavelength by fiber channel is 280 nanometers to 320 nanometers
Medium wave ultraviolet light, baffle is for closing both ends.It can occur after irradiation of the ZnO nano-wire by ultraviolet light along axial tension
Phenomenon to change cross sectional shape and length, and then causes thermal resistance to change, and realization achievees the purpose that control hot-fluid.
Technical solution of the present invention makes ZnO nano by applying ultraviolet light on ZnO nano-wire using light flex effect
Line generates stretching, causes thermal resistance to increase, so that hot-fluid be made to reduce.Stretching for ZnO nano-wire can be controlled by can be changed ultraviolet ray intensity
Contracting amount is realized to the real-time control of hot-fluid, expands the scope of application and efficiency of hot rectifier.
On the basis of the above, the present invention accordingly discloses a kind of method for improving the hot rectification efficiency of hot rectifier, utilizes light
Flex effect changes ZnO nano-wire thermal resistance, improves hot rectification efficiency.
Detailed description of the invention
