Term is stated in concrete meaning of the invention.
The present invention operation principle be：
Heat-exchange power W=mc Δ t, wherein quality and specific heat capacity is almost unchanged, in order to increase heat exchange
Energy W only increases temperature difference Δ t.Under normal circumstances because there is the presence in relative low temperature area and relatively-high temperature area, heat exchange
Interface temperature difference is smaller, i.e. Δ t is smaller.In order to improve the defect of traditional thermal energy converter, the present apparatus uses the principle of resonance,
So that spiral spring type heat exchange hollow pipe is in reciprocal ceaselessly vibration motion state, makes the liquid at tube wall by original
Flowing velocity slows down even immobilising laminar condition and becomes turbulent condition because the not failure of oscillation of heat-exchange tube is dynamic, has broken hot friendship
The exchange media flow velocity field around the inside and outside wall of pipe and temperature gradient field distribution are changed, the medium flow field inside and outside heat exchange tube wall is made
Dynamic velocity field and temperature gradient distribution reach the balanced level of comparison, to increase temperature difference Δ inside heat-exchange tube and external
T improves the heat exchanger effectiveness between cold water and hot water.
In order to realize the exchange pipe resonance of heat exchanger, special exciting device is provided in the thermal energy converter.From
The angle for saving the energy is set out, which is not arranged special power source, but the kinetic energy by the way that hot water is flowed and
Pressure potential is converted to the kinetic energy that electric fan is rotated around its own rotary shaft, allows and flows through spiral spring type heat exchange hollow pipe
Water flow pressure generates fluctuation, excites the hollow pipe resonance of spiral spring type heat exchange, when electric fan excited frequency is equal to spiral
The spiral spring type heat exchange hollow pipe generates resonance when the intrinsic frequency of spring type heat exchange hollow pipe, makes original heat exchanger
Working media around interior cored screw spring tube wall section is finally reached since the effect of resonance becomes turbulent flow and breaks the pipe
Liquid flow velocity field around wall and thermo parameters method increase the purpose of heat exchange interface temperature difference.The tune of vibrator frequency
Section：The power source of fan blade profile vibrator is flowing hot water, so the inlet and outlet pressure difference for flowing hot water by change is
Changeable vibrator rotating speed, so as to adjust the vibration frequency of electric fan excitation hot water flowing.Thus in the thermal energy converter
Pressure reducing valve is added to control to adjust hot water flowing pressure, the pressure by change hot water is final to adjust flow velocity and flabellum rotating speed
Achieve the purpose that adjusting vibration exciter frequency.
Resonance principle：In the apparatus, exciting source is fan blade profile vibrator, the kinetic energy and pressure potential that hot water is flowed
The kinetic energy that flabellum is rotated around its own rotary shaft can be converted to, allow flow through spiral spring type heat exchange hollow pipe water flow pressure and
Flow velocity generates fluctuation, when the vibration frequency of exciting source is equal to the intrinsic frequency of spiral spring type heat exchange hollow pipe, to swash
The hollow pipe resonance of spiral spring type heat exchange is sent out, since the hot water inlet pressure from the exchanger is with its outlet pressure difference
It is set up by pressure reducing valve, the flowing water speed and pressure difference driving flabellum do not stop to rotate, and spiral spring type heat exchange hollow pipe will
It can obtain Persistent Excitation and constantly vibrate, which has broken the flow velocity field and temperature of the working media around hollow tube wall
Field distribution is spent, spiral spring type heat exchange hollow pipe is made to be in the resonance state of certain amplitude.The heat of traditional thermal energy converter is handed over
It is straight tube, intrinsic frequency to change pipeWherein quality is fixed by design standard due to the material and size of heat-exchange tube, so
Quality not malleable, and the rigidity of straight tube is larger, so intrinsic frequency is higher, is not likely to produce resonance, the heat of the thermal energy converter
It is spiral spring type heat exchange hollow pipe to exchange pipe, and rigidity is small, and the quality of unit length increases, so intrinsic frequency subtracts significantly
It is small, realize that resonance provides advantage for the device.Furthermore due to the hammer vibration energy of fan blade profile vibrator be not it is very big,
In addition the presence that spiral spring type heat-exchange tube damps when vibrating in water, is in so as to avoid spring type heat exchange hollow pipe
The resonance state of large amplitude would not also generate the dynamic stress of high-amplification-factor, damage this resonant high-efficient thermal energy exchanger.
1 to Fig. 5 the implementation of the device is further described below in conjunction with the accompanying drawings：
Traditional heat exchanger, it is miscellaneous due to exchanging interface tracheid shape properties, incrustation scale etc. in the heat exchanging process of hot and cold water
The influence of matter and adhesive force so that the flow resistance of the hot and cold water of heat exchange near-wall is larger, allows liquid at the tube wall
Flowing velocity slows down or even does not flow, and seriously reduces rate of heat exchange.The present invention proposes resonant high-efficient thermal energy exchanger,
Above-mentioned drawback is overcome, heat exchanger effectiveness is substantially increased, reduces the maintenance frequency and maintenance cost of equipment；It is mainly by cold
Water lines, hot water tube system, exciting device, heat exchange container composition, the hollow exchange pipe of the heat exchange container is spiral bullet
Spring shape, electric fan is flowed through by the hot water of pressure reducing valve, the kinetic energy and pressure potential of hot water flowing are converted to fan
The kinetic energy that leaf is rotated around its own rotary shaft allows the water flow pressure for flowing through spiral spring type heat exchange hollow pipe to generate fluctuation, when
When the vibration frequency of exciting source is equal to the intrinsic frequency of spiral spring type heat exchange hollow pipe, to excite the spiral spring type hot
Exchange hollow pipe resonance, due to from the exchanger hot water inlet pressure and its outlet pressure difference be to be set up by pressure reducing valve
, which does not stop to rotate, and spiral spring type heat exchange hollow pipe will obtain lasting resonance excitation,
The flowing velocity and temperature gradient distribution state of the working media around hollow tube wall have been broken in the resonance, not only increase in this way
The exchange efficiency of heat exchanger, and avoid generation of the incrustation scale on heat exchange tube wall.
Concrete structure resonant high-efficient thermal energy exchanger as shown in Figure 4, the rightmost side of whole device is pressure reducing valve, hot water
Enter pressure reducing valve 11 by the hot water inlet 12 of pressure reducing valve, the hot water inlet 6 of heat exchange container 9 is entered after decompression, passes through half
4 hot water of spherical end cover pushes electric fan 5 to be rotated around axis 20, and the kinetic energy and pressure potential of hot water flowing are converted to electric fan
5 kinetic energy rotated around its own rotary shaft 20 allow the water flow pressure for flowing through spiral spring type heat exchange hollow pipe 15 to generate fluctuation,
When the vibration frequency of exciting source is equal to the intrinsic frequency of spiral spring type heat exchange hollow pipe, to excite the spiral spring type
Heat exchange hollow pipe 15 resonates, and is to pass through decompression since 6 pressure of hot water inlet from the exchanger exports 10 pressure differences with it
What valve 11 was set up, which does not stop to rotate, and spiral spring type heat exchange hollow pipe 15 will be continued
Resonance excitation, which has broken the flowing velocity and temperature gradient distribution state of the working media around hollow tube wall, has added
Fast heat exchanger effectiveness, and prevent the impurity in hot water from being accumulated on water pipe and form incrustation scale.Since spiral spring type heat exchange is empty
Heart pipe can increase contact area, to increase heat exchanger effectiveness.Hot water warp in spiral spring type heat exchange hollow pipe 15
