Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.
As shown in fig. 1 to 7, for the cavity type gas-liquid two-phase heat absorber structure provided by the present invention, it includes a shell 12, the shell 12 is provided with an optical inlet 16, a gas working medium inlet 17, a liquid working medium inlet 18, a gas working medium outlet 19, and a liquid working medium outlet 20; a cavity in the heat absorber is provided with a coil pipe 8, the coil pipe 8 is connected with a liquid working medium inlet 18 and a liquid working medium outlet 20, and a heat absorber is arranged in the cavity, wherein the heat absorber comprises an outer heat absorber 3, a middle heat absorber 2 and an inner heat absorber 9, the outer heat absorber 3 is coated outside the coil pipe 8, the middle heat absorber 2 is arranged between two layers of the coil pipe 8, and the inner heat absorber 9 is arranged in the coil pipe 8; a reflecting cone 4 is also provided within the cavity, wherein the reflecting cone 4 is arranged opposite the optical inlet 16 for launching a pipeline entering through the optical inlet 16 to the coil 8 and the heat absorber.
The utility model discloses a coil pipe 8 is double-deck spiral coil pipe, and liquid working medium preheats in the lower spiral coil pipe outer lane of 18 entering temperatures of liquid working medium entry, then the higher spiral coil pipe inner circle of reentrant temperature continues the heating, flows out from liquid working medium export 20 at last. The use of the structure greatly increases the heat exchange area, strengthens the heat exchange effect and fully utilizes the energy in the cavity.
The light gathered by the disc condenser passes through the optical inlet and is reflected to the inner wall of the spiral coil 8 through the reflecting cone 4 so as to heat the spiral coil, and the reflecting cone 4 is arranged at the rear cover plate 6 through the reflecting cone bottom plate 7. Because only one side is directly heated and the other side is heat conduction, the temperature difference between the inner wall and the outer wall of the spiral coil 8 is high, which is not beneficial to heat exchange. And the flowing direction of the fluid is changed at every moment in the flowing process of the fluid in the spiral coil 8, and the speed in the spiral coil 8 is low as the inner ring speed and high as the outer ring speed due to the action of centrifugal force.
Because the superposition of the two defects causes the difference between the internal temperature and the external temperature of the fluid in the coil 8 to be larger, the existence of the temperature gradient is not beneficial to the stability of the internal flow field of the working medium, and the heat conversion efficiency of the heat absorber is also reduced. For solving the problem the utility model discloses improve on original copper pipe coil pipe 8 basis, at coil pipe 8's internal design spiral copper line to the inside working medium disturbance of reinforcing coil pipe, spiral copper line adopts snakelike arrangement mode to arrange inside coil pipe 8. This structure can destroy the flow state through increasing spiral copper line in intraductal, and the increase disturbance strengthens heat transfer effect, makes intraductal fluid fully fuse simultaneously for the working medium temperature that flows is even, has reduced the radial temperature gradient of coil pipe. The increase of the spiral copper wire also increases the heat exchange area, and is beneficial to improving the overall heat exchange efficiency. Set up the helix in coil pipe 8, make copper line and copper pipe wall fully contact, the wall contact of copper line and copper pipe is just more abundant behind the coiler coil pipe. The spiral coil 8 transfers energy to the spiral copper wires in a heat conduction mode, on one hand, heat is transferred to a backlight surface along a spiral line, the temperatures on two sides are balanced, and the temperature gradient of the coil 8 can be reduced; on the other hand, the spiral copper wire and the liquid working medium exchange heat in a convection mode, and the heat exchange effect can be enhanced due to the fact that the heat exchange area is increased.
In the present invention, the heat absorbing body is a heat storage body. The material can be porous medium, copper net, aluminum net and other metal with good heat conductivity. The heat absorbing body structure has a good three-dimensional flow guiding structure, large specific surface area, good heat conducting performance and light weight, and can strengthen heat exchange.
The arrangement mode of the heat absorber in the cavity has the following characteristics: part of light reflected by the reflecting cone 4 directly irradiates the inner heat absorber 9, so that the inner heat absorber 9 absorbs energy, and the energy of the inner heat absorber 9 can be directly transferred to the spiral coil 8 in a heat conduction mode due to the fact that the inner heat absorber 9 is in contact with the inner ring of the spiral coil 8, and the temperature of the spiral coil 8 is increased; the other part of light passes through the inner heat absorber 9 to directly irradiate the inner ring wall surface of the spiral coil 8 because the heat absorber 9 is in a hollow structure, so that the spiral coil 8 absorbs energy and the temperature is increased. Because the cavity is in a completely sealed state, the energy loss is small, and part of the energy of the gas medium in the cavity directly exchanges heat with the wall surface of the spiral coil 8; another part of the energy may be transferred to the heat absorbing body. Wherein, the energy of the middle heat absorption body 2 and the outer heat absorption body 3 mostly comes from the heat exchange with the gas medium. And the middle heat absorber 2 and the outer heat absorber 3 are both in contact with the wall surface of the spiral coil 8, so that the energy obtained by the heat exchange between the middle heat absorber 2 and the outer heat absorber 3 and the gas medium is transferred to the spiral coil 8 in a heat conduction mode, and the temperature of the spiral coil 8 is increased. The method of placing the heat absorber and the spiral coil 8 in a partition wall type can also greatly solve the problem of non-uniformity of the wall temperature of the inner ring and the outer ring of the spiral coil 8.
The heat absorption body is used in a large amount in the cavity, and heat can be stored for a short time. The dish-type light-focusing heat collector is point-focusing, has extremely high requirement on irradiance, has great influence on energy in the cavity when the irradiance fluctuates greatly, and ensures that the temperature of the outlet working medium is unstable. This situation is even more severe if cloudy weather is encountered. After a large number of heat absorbing bodies are added into the cavity, redundant energy can be stored in the heat absorbing bodies under high irradiance, and the heat absorbing bodies can emit heat under low irradiance to supplement energy, so that the temperature of the outlet working medium is kept stable.
Due to the fact that solar rays are not parallel to each other and the manufacturing error of the disc condenser is caused, point focusing cannot be completely achieved for the collected rays, a small part of rays irradiate the outer side of a front end cover (the front end cover refers to a cover plate at one end, close to a light inlet, of the shell) of the cavity, the front end cover absorbs energy, and a gas medium in the cavity can exchange heat with the inner side of the front end cover, so that the front end cover absorbs energy. The two terms are superposed, a part of energy can be stored in the front end cover, the end cover has a larger temperature difference with the ambient temperature, convection heat exchange can be carried out, and the energy loss on the quartz glass 11 account for most of the total energy loss of the cavity type heat absorber.
For the temperature that reduces front end housing and quartz glass 11, reduce energy loss, also do not damage because of thermal stress is too big for protection quartz glass 11 simultaneously, the utility model discloses improve the air inlet, admit air traditional straight tube and change into annular intake pipe 1, two kinds of holes of exhaust hole 14 and side exhaust hole 15 under the annular intake pipe 1 divide into. The lower vent hole 14 is perpendicular to the front end cover, the discharged gas blows to the front end cover, the side vent hole 15 forms an angle of 45 degrees with the front end cover, and the discharged gas blows to the quartz glass 11. The improved structure strengthens the heat exchange effect of the front end cover and the quartz glass 11 with the gas medium, and reduces the energy loss of the front end cover and the quartz glass.
The working principle of the utility model is as follows:
light ray process:
the heat absorber is arranged on the disc-type condenser, light rays are converged by the condenser and then enter the cavity through the optical inlet 16 and the quartz glass 11, and then the light rays are reflected to the inner heat absorber 9 and the spiral coil 8 by the reflecting cone 4, so that the inner heat absorber 9 and the spiral coil 8 are heated.
Liquid medium flow:
the liquid working medium enters the spiral coil 8 from the liquid working medium inlet 18, is preheated at the outer ring of the spiral coil 8, then enters the inner ring for continuous heat exchange, and finally flows out from the liquid working medium outlet 20 to finish the heat exchange of the liquid working medium.
Gas working medium flow:
gas working medium enters the air inlet pipe 1 from the gas working medium inlet 17, enters the cavity from the exhaust hole on the air inlet pipe, passes through the inner heat absorber 9, the middle heat absorber 2 and the outer heat absorber 3 to move upwards, is mixed by the rear heat absorber 5 and then is discharged from the gas working medium outlet 19, and the heat exchange of the gas working medium is completed.
The overall heat absorber work flow is as follows:
the heat absorber is arranged on the disc-type condenser, sunlight rays enter the cavity from the optical inlet 16 through the quartz glass 11 after being converged by the condenser, the energy of focused light spots entering the cavity is distributed into concentric circles, the energy at the center of the circle is the highest, and the energy is lower when the distance from the center is farther. The light of the low energy part directly irradiates to the lower end faces of the spiral coil pipe 8 and the inner heat absorption body 9, the light of the high energy part irradiates to the inner heat absorption body 9 through the reflection of the reflection cone 4, and the inner heat absorption body 9 is of a hollow structure, so that part of the light irradiating to the inner heat absorption body can irradiate to the spiral coil pipe 8 through the refraction of the ribs or directly penetrates through the holes, and the spiral coil pipe 8 and the inner heat absorption body 9 can absorb the energy of the light irradiating to the spiral coil pipe 8. The structural arrangement greatly increases the heat absorption area and strengthens the heat absorption performance. In the process, the spiral coil 8 and the inner heat absorber 9 both have heat energy, the spiral coil 8 and the inner heat absorber 9 are in mutual contact, and the energy absorbed by the inner heat absorber 9 can be transferred to the spiral coil 8 in a heat conduction mode. Meanwhile, gas working medium enters the gas inlet pipe 1 from the gas working medium inlet 17 and enters the cavity from the exhaust hole on the gas working medium inlet pipe, the gas in the lower exhaust hole 14 is blown to the front end cover, the gas in the side exhaust hole 15 is blown to the quartz glass 11, and forced convection is formed when the gas flows through the front end cover and the quartz glass 11, so that the energy of the front end cover and the quartz glass 11 is taken away. When flowing upwards, the gas passes through the middle heat absorbing body 2, the outer heat absorbing body 3 and the rear heat absorbing body 5, and at the moment, the gas working medium exchanges heat with the middle heat absorbing body 2 and the outer heat absorbing body 3, and the process can also be called a heat storage process. The middle heat absorber 2, the outer heat absorber 3 and the rear heat absorber 5 are also in contact with the spiral coil 8, and the stored heat can be transferred to the spiral coil 8 in a heat conduction mode. And finally, discharging the heated gas working medium out of the cavity. The problem of uneven energy distribution in the cavity can be solved by the flowing of the gas working medium in the cavity, so that the heat exchange efficiency is improved. Liquid working medium enters the spiral coil 8 from the liquid working medium inlet 18, and is preheated in the outer spiral coil 8 between the outer heat absorber 3 and the middle heat absorber 2, so that the heat exchange area is increased, and the energy in the cavity can be fully utilized. The preheated liquid working medium enters the inner ring of the spiral coil 8 with higher temperature to continuously exchange heat, and finally flows out from the liquid working medium outlet 20 to finish the heat exchange of the liquid working medium.
