(6) A compressor that compresses a heat medium, a heat exchanger that dissipates heat from the heat medium compressed by the compressor, and molecules of the heat medium that dissipate heat from the heat exchanger are vibrated and rotated to radiate energy. A power generation unit is arranged between the heat exchanger and the spiral thin tube of the heat exchange unit having the spiral thin tube to be liquefied under reduced pressure, and the heat exchanger side of the power generation unit and the spiral thin tube are provided. A power generation method characterized in that the power generation unit is driven by utilizing the pressure difference of the heat medium from the side.

FIG. 1 is a diagram showing an overall configuration of a power generation device. FIG. 2 is a cross-sectional view showing a groove structure when the spiral tube, which is the main part of the speed-heat exchanger of FIG. 1, is a straight tube. FIG. 3 is a cross-sectional view showing a power generation unit included in the power generation device of FIG.

FIG. 1 shows a configuration of a power generation device according to a preferred embodiment. The power generation device 1 shown in FIG. 1 includes a compressor 2 (compressor), a heat exchanger 3 (capacitor), a speed-heat converter 4, and a power generation unit 5. Of these, the compressor 2, the heat exchanger 3, and the speed-heat exchanger 4 constitute a heat exchange unit 10.

In such a power generation device 1, the heat medium Q (refrigerator) is compressed by the compressor 2 into a high-temperature and high-pressure gaseous heat medium Q, and the high-temperature and high-pressure gaseous heat medium Q discharged from the compressor 2 is converted into a high-temperature and high-pressure gaseous heat exchanger 3. The heat medium Q, which was liquefied at room temperature and high pressure by heat exchanger 3 and vaporized at room temperature and high pressure, was vaporized by the speed-heat exchanger 4 to be gasified at low temperature and low pressure. It operates in a heat exchange cycle in which the heat medium Q, which has become a low-temperature low-pressure gaseous state in 4, is compressed again by the compressor 2 into a high-temperature high-pressure gaseous state. Further, the power generation device 1 has a power generation unit 5 arranged between the heat exchanger 3 and the speed-heat converter 4, and has a heat exchanger 3 side and a speed-heat converter 4 side of the power generation unit 5. The power generation unit 5 is driven by using the pressure difference of the heat medium Q of the above, and power is generated.

The heat medium Q used in the power generation device 1 is not particularly limited, but for example, it is preferable that the discharge pressure is high and the pressure difference between the discharge pressure and the suction pressure is large.

The speed-heat converter 4 has a spiral thin tube 41, a spiral thick tube 42, and a relay tube 43 located between the spiral thin tube 41 and the spiral thick tube 42 and connecting them. That is, the spiral thin tube 41 and the spiral thick tube 42 are connected in series via the relay tube 43. The heat medium Q, which has become liquid at room temperature and high pressure in the heat exchanger 3, is introduced into the spiral thin tube 41, and the molecules of the heat medium Q vibrate and rotate in the spiral thin tube 41 to radiate energy. The heat medium Q is decompressed and liquefied by the energy radiation due to this vibration rotation, and the heat medium Q is vaporized (gasified) in the relay pipe 43 located downstream thereof, and becomes a moist gaseous state. The heat medium Q, which has become moist and gaseous in the relay tube 43, is introduced into the spiral thick tube 42, and the molecules of the heat medium Q vibrate and rotate in the spiral thick tube 42 to radiate energy. The heat medium Q is completely vaporized (gasified) by the energy radiation generated by this vibration rotation. The heat medium Q, which has become gaseous in the spiral thick tube 42, is introduced into the compressor 2 and becomes gaseous again at high temperature and high pressure. In such a speed-heat exchanger 4, the spiral thin tube 41 plays the role of a pressure reducing valve, and the spiral thick tube 42 plays the role of an evaporator. However, the evaporator is not limited to the spiral thick tube 42.

To briefly explain the above-mentioned phenomenon of energy radiation with some speculation, when the heat medium Q is introduced into the spiral capillary tube 41, friction occurs between the molecules of the heat medium Q, and the molecules collide with each other. Molecules vibrate and rotate repeatedly as they separate. Then, a centrifugal force is applied to the vibrating and rotated molecules, and energy is radiated from the molecules when the centrifugal force reaches a certain magnitude or more. The same applies to the spiral thick tube 42.

In the illustrated configuration, two series tubes 40 in which the spiral thin tube 41 and the spiral thick tube 42 are connected by the relay tube 43 are provided in parallel. However, the number of series tubes 40 is not particularly limited, and may be one or three or more in parallel. The number of series tubes 40 can be appropriately set according to, for example, the capacity of the heat medium.

Further, a collecting pipe 44 for connecting the plurality of spiral thin tubes 41 is connected to the end of each series tube 40 on the spiral thin tube 41 side. Further, a collecting pipe 45 for connecting the plurality of spiral thick pipes 42 is connected to the end of each series pipe 40 on the spiral thick pipe 42 side.

The inner diameter of the spiral thin tube 41 is smaller than the inner diameter of the spiral thick tube 42. The inner diameter of the spiral thin tube 41 may be smaller than the inner diameter of the spiral thick tube 42, and can be appropriately set depending on the heat medium capacity or the like, and can be, for example, about 1 to 5 mm. Similarly, the inner diameter of the spiral thick tube 42 may be larger than the inner diameter of the spiral thin tube 41, and can be appropriately set depending on the heat medium capacity or the like, and can be, for example, about 2 to 10 mm. ..

Further, the spiral diameter of the spiral thin tube 41 is smaller than the spiral diameter of the spiral thick tube 42. The spiral diameter of the spiral thin tube 41 can be appropriately set depending on the heat medium capacity and the like, and can be, for example, about 15 to 20 mm. Similarly, the spiral diameter of the spiral thick tube 42 can be appropriately set depending on the heat medium capacity and the like, and can be, for example, about 35 to 40 mm. However, the spiral diameters of the spiral thin tube 41 and the spiral thick tube 42 and their magnitude relations are not limited to this.

Further, the total length of the spiral thin tube 41 is shorter than the total length of the spiral thick tube 42. The total length of the spiral thin tube 41 can be appropriately set depending on the heat medium capacity and the like, and can be, for example, about 500 to 1000 mm. Similarly, the total length of the spiral thick tube 42 can be appropriately set depending on the heat medium capacity and the like, and can be, for example, about 1500 to 2000 mm. However, the total length of the spiral thin tube 41 and the spiral thick tube 42 and their magnitude relations are not limited to this.

The spiral thin tube 41 and the spiral thick tube 42 as described above are formed by, for example, the following method. First, a copper tube is prepared, a piano wire is inserted into the copper tube, and the copper tube is squeezed to the outer diameter (thickness) of the piano wire to form a straight tube. Further, by winding this straight tube in a spiral shape to form a spiral tube, the spiral thin tube 41 and the spiral thick tube 42 are formed.

By twisting the copper tube in this way, as shown in FIG. 2, an inclined groove 4a is formed in the inner wall of the spiral thin tube 41 and the spiral thick tube 42. The groove 4a is formed so as to proceed while turning left from the spiral thick tube 42 side toward the spiral thin tube 41 side. Furthermore, by spirally winding the straight pipe in which the groove 4a is formed, the outside of the spiral is pulled in the length direction as a whole, and the pitch of the groove 4a is wider than that in the straight pipe state, which is the opposite. In addition, the inside of the spiral is compressed in the length direction as a whole, and the pitch of the groove 4a becomes narrower than that in the straight pipe state. Further, in the process of spirally winding the straight tube, at least one "neck" is formed by twisting the copper tube in the axial direction. The feed angle and pitch of the groove 4a and the position and number of "neck" formations are appropriately set for the spiral thin tube 41 and the spiral thick tube 42, respectively.

As described above, the pitch of the groove 4a is different between the outside and the inside of the spiral tube, and further, due to the formation of the "neck", the heat medium is formed in the spiral thin tube 41 and the spiral thick tube 42. Q oscillates and rotates, which has a particularly favorable effect on heat conversion in the speed-heat exchanger 4. In other words, in the spiral thin tube 41 and the spiral thick tube 42, the feed angle and pitch of the groove 4a and the formation position and number of the "neck" are set so that the heat medium Q oscillates and rotates inside the spiral thin tube 41 and the spiral thick tube 42. However, this is an example, and the configuration and forming method of the spiral thin tube 41 and the spiral thick tube 42 are not particularly limited as long as they can exhibit the above-mentioned functions.

As shown in FIG. 1, the compressor 2 and the heat exchanger 3 are connected by a pipe 61, the heat exchanger 3 and the collecting pipe 44 are connected by a pipe 62, and the collecting pipe 45 and the compressor 2 are connected. Is connected by a pipe 63. Of these, the inner diameters of the pipes 62 and 63 are preferably larger than those of the spiral thick pipe 42, and can be, for example, about three times the inner diameter of the spiral thick pipe 42. The heat exchanger 3 dissipates heat from the heat medium Q, which is compressed by the compressor 2 and becomes a high-temperature and high-pressure gas, and is cooled by a fan.

Further, a power generation unit 5 is provided in the middle of the pipe 62 connecting the heat exchanger 3 and the collecting pipe 44. As shown in FIG. 3, the power generation unit 5 transmits the generator 54, the power generation unit 50 that generates power for driving the generator 54, and the power generated by the power generation unit 50 to the generator 54. It has a power transmission unit 55 and. Further, the power generation unit 50 is connected in the middle of the pipe 62 and is arranged in the airtight housing 51 through which the heat medium Q passes, and the heat medium Q arranged in the housing 51 and flowing in the housing 51. It has a rotating impeller 52 (rotated body), an output shaft 53 that outputs the rotation of the impeller 52, and a generator 54 connected to the output shaft 53. In the following, for convenience of explanation, the portion between the power generation unit 5 of the pipe 62 and the heat exchanger 3 is also referred to as the first pipe 621, and the portion between the power generation unit 5 of the pipe 62 and the spiral thin tube 41 is the second. Also called piping 622.

Such a power generation unit 5 has a pressure difference between the upstream side and the downstream side of the housing 51, that is, the pressure of the heat medium Q in the first pipe 621 connected to the upstream side of the housing 51 and the downstream side of the housing 51. The impeller 52 rotates in the housing 51 due to the difference from the pressure of the heat medium Q in the second pipe 622 connected to the side.

Specifically, as described above, the heat medium Q is liquefied at room temperature and high pressure by radiating and liquefying it in the heat exchanger 3, and is liquefied under reduced pressure in the spiral thin tube 41 to become a moist liquid. In this way, the heat medium Q radiated by the heat exchanger 3 is depressurized by the spiral thin tube 41 located on the downstream side thereof, so that a pressure difference of the heat medium Q is generated in the pipe 62 located between them. , The upstream side has a higher pressure than the downstream side. Therefore, if the power generation unit 5 is arranged in the middle of the pipe 62, the pressure on the upstream side of the housing 51 becomes higher than that on the downstream side, and the impeller 52 in the housing 51 rotates due to this pressure difference. When the impeller 52 rotates according to such a principle, the rotation is output as power from the output shaft 53, and this power drives the generator 54 connected to the output shaft 53 to start power generation.

Here, the power generation unit 50 is arranged unevenly on the downstream end side (spiral thin tube 41 side) of the central portion in the extending direction of the pipe 62. That is, the second pipe 622 is longer than the first pipe 621. As a result, the pressure difference described above can be further increased, and the power generation efficiency of the power generation device 1 is improved.

The configuration of the power generation unit 50 is not limited to the above configuration, and may be any configuration as long as it can generate power to drive the generator 54. For example, as the impeller 52, an axial fan, a centrifugal fan (sirocco fan, turbo fan, etc.), a mixed flow fan, a cross flow fan, or the like can be used. Further, as the power generation unit 50, a compressor for a car air conditioner can also be used. In a car air conditioner, a pulley provided in the compressor is rotated by the power of the engine, and the piston in the compressor is driven by the rotation of the pulley to compress the heat medium Q. On the contrary, the pressure difference described above is used. The piston may be driven by using the above, the pulley may be rotated by the drive of the piston, and the generator 54 may be driven by the rotation of the pulley.

Further, the generator 54 is not particularly limited as long as it can exhibit its function. For example, in an alternator having a pair of coils and a magnet arranged between the pair of coils and connected to the output shaft 53, the magnet is rotated between the pair of coils by the rotation of the output shaft 53. It may or may not be present, and on the contrary, it has a pair of magnets and a coil arranged between the pair of magnets and connected to the output shaft 53, and a pair of coils are formed by rotation of the output shaft 53. It may be a DC generator that rotates between magnets. Further, a generator having any structure different from these may be used.

The power transmission unit 55 includes a pulley 551 provided on the output shaft 53, a pulley 552 provided on the generator 54, and a belt 553 connecting the pulleys 551 and 552. In the illustrated configuration, the pulley 552 is smaller than the pulley 551, so that the power transmission unit 55 functions as a speed increaser. However, the configuration of the power transmission unit 55 is not particularly limited as long as the power generated by the power generation unit 50 can be transmitted to the generator 54, and has, for example, a function as a speed reducer, a transmission, or the like. May be good. Further, the power transmission unit 55 may be omitted, and the output shaft 53 may be directly connected to the generator 54.

The configuration of the power generation device 1 has been described above. Next, a power generation method using the power generation device 1 will be described. The power generation method is only to drive the power generation device 1 in the cycle indicated by the arrow A in FIG. That is, the heat medium Q is compressed by the compressor 2 into a high-temperature and high-pressure gas. The high-temperature, high-pressure gaseous heat medium Q discharged from the compressor 2 is introduced into the heat exchanger 3, dissipates and liquefies in the heat exchanger 3, and becomes a liquid at room temperature and high pressure. The heat medium Q, which has become liquid at room temperature and high pressure in the heat exchanger 3, is introduced into the spiral thin tube 41, and the molecules of the heat medium Q vibrate and rotate in the spiral thin tube 41 to radiate energy. The heat medium Q is liquefied under reduced pressure by the energy radiation caused by the vibrational rotation of the heat medium molecules, and the heat medium Q is gasified in the relay tube 43 located downstream thereof, and becomes a wet gaseous state. The heat medium Q, which has become moist and gaseous in the relay tube 43, is introduced into the spiral thick tube 42, and the molecules of the heat medium Q vibrate and rotate in the spiral thick tube 42 to radiate energy. The heat medium Q is completely gasified by the energy radiation caused by the vibrational rotation of the heat medium molecules. The heat medium Q, which has become gaseous in the spiral thick tube 42, is introduced into the compressor 2 and becomes gaseous again at high temperature and high pressure. Then, the pressure difference of the heat medium Q generated by such a cycle drives the power generation unit 5 arranged between the heat exchanger 3 and the spiral thin tube 41, and power generation is started. If the spiral thick tube 42 cannot be sufficiently vaporized, another evaporator may be arranged on the downstream side of the spiral thick tube 42 to assist the vaporization.

According to the power generation device 1 according to the present invention, the molecules of the heat medium Q are subjected to vibrational rotation in each of the spiral thin tube 41 and the spiral thick tube 42, and kinetic energy is continuously radiated, so that high efficiency is achieved during power generation. It is possible to reduce energy consumption. Theoretically, the compressor pressure can be reduced by 20-40% and the power consumption can be reduced by 60-80%. According to such a power generation device 1, theoretically, the generator 54 can generate more electric power than the electric power consumed by driving the power generation device 1.

As described above, the power generation device 1 according to the present invention has a compressor 2 that compresses the heat medium Q, a heat exchanger 3 that dissipates heat from the heat medium Q compressed by the compressor 2, and heat exchanger 3 that dissipates heat. It has a spiral capillary tube 41 that vibrates and rotates the molecules of the heat medium Q to be vaporized, and a power generation unit 5 provided between the heat exchanger 3 and the spiral capillary tube 41. Therefore, the amount of electric power used by the power generation device 1 can be significantly reduced. Therefore, its industrial applicability is great.
