<First Embodiment>
First, the heat sink 100 according to the first embodiment of the present invention will be described.

The heat removal device 100 shown in FIG. 1 is a device capable of instantaneously removing heat, that is, cooling water W (H ₂ O) as a heat removal target. Such a heat removal device 100 includes a compressor 110 (compressor) that compresses a refrigerant Q (heat medium) into a high-temperature and high-pressure gas refrigerant Q1, and a compressor 110 that condenses the high-temperature and high-pressure gas refrigerant Q1 from the compressor 110. A condenser 120 (condenser) for high-pressure liquefied gas refrigerant Q2, and a first spiral tube 130 (large spiral tube) for depressurizing and liquefying high-pressure liquefied gas refrigerant Q2 from the condenser 120 to form liquid refrigerant Q3. , the second spiral tube 140 (spiral thin tube) that decompresses and expands the liquid refrigerant Q3 from the first spiral tube 130 to obtain a low-temperature and low-pressure liquid refrigerant Q4, and the liquid refrigerant Q4 from the second spiral tube 140. It has an evaporator 150 that evaporates into a low-pressure gas refrigerant Q5 and a pipe 160 that connects them. In such a heat removal device 100, heat is exchanged between the refrigerant Q and the water W in the evaporator 150, and heat is removed from the water W instantly. It should be noted that the target for heat removal is not limited to water W, and may be any liquid or gas.

The refrigerant Q used in the heat removal device 100 is not particularly limited. For example, various natural refrigerants such as HFC-134a, R-1234yf, etc., ammonia: NH ₃ , carbon dioxide gas: CO _2, etc. can be used. However, among these, it is preferable to use a refrigerant that has a low ozone depletion potential and a low global warming potential and is friendly to the environment.

[Compressor 110]
Compressor 110 compresses gas refrigerant Q5 from evaporator 150 into high-temperature and high-pressure gas refrigerant Q1.

[Condenser 120]
Condenser 120 is arranged downstream of compressor 110 and receives gas refrigerant Q1 from compressor 110 . The condenser 120 uses a fan 121 to blow air into the pipe, thereby releasing heat from the gas refrigerant Q1 flowing through the pipe. As a result, part of the gas refrigerant Q1 is liquefied to become a high-pressure liquefied gas refrigerant Q2 (wet gaseous refrigerant). Although the amount of liquefaction is not particularly limited, it is sufficient that about 70% to 80% of the entire gas refrigerant Q1 can be liquefied. With such a configuration, the size of the condenser 120 can be reduced.

[First spiral tube 130]
The first helical tube 130 is arranged downstream of the condenser 120 and receives the liquefied gas refrigerant Q2 from the condenser 120 . Two first helical tubes 130 are arranged in parallel, and a collecting pipe 131 is connected to the upstream end side of the two first helical tubes 130, and is also connected to the downstream side. A collecting pipe 132 is connected. The collecting pipe 131 functions as a buffer for smoothly introducing the liquefied gas refrigerant Q2 into the first spiral pipe 130 .

When the liquefied gas refrigerant Q2 from the condenser 120 is introduced into the first spiral tube 130, the molecules of the refrigerant Q (hereinafter also referred to as “refrigerant molecules”) vibrate and rotate in the first spiral tube 130, and energy radiate. The liquefied gas refrigerant Q2 is decompressed and liquefied by the radiation of energy due to the vibration and rotation of the refrigerant molecules, and the refrigerant Q becomes more moist than the liquefied gas refrigerant Q2. In particular, in the present embodiment, almost 100% of the refrigerant Q becomes liquid refrigerant Q3 (liquid refrigerant).

Here, the aforementioned energy radiation phenomenon will be briefly described with some speculation. When the refrigerant Q is introduced into the first helical tube 130, friction occurs between the molecules of the refrigerant Q, and the refrigerant molecules repeatedly collide and separate, causing the refrigerant molecules to vibrate and rotate (this is called “vibration and rotation”). ”). Furthermore, the vibration and rotation apply a centrifugal force to the refrigerant molecules, and when the centrifugal force reaches a certain level or more, the refrigerant molecules radiate energy. Due to this energy radiation, the liquefied gas refrigerant Q2 is liquefied under reduced pressure to become a liquid refrigerant Q3.

The inner diameter of the first helical tube 130 is larger than the inner diameter of the second helical tube 140 . The inner diameter of the first helical tube 130 is not particularly limited, but can be, for example, about 2 mm to 10 mm. Also, the spiral diameter of the first spiral tube 130 is larger than the spiral diameter of the second spiral tube 140 . The spiral diameter of the first spiral tube 130 is not particularly limited, but can be, for example, about 30 mm to 50 mm. Also, the first helical tube 130 is longer than the second helical tube 140 . The length (total length) of the first helical tube 130 is not particularly limited, but can be, for example, approximately 1500 mm to 2000 mm. Each dimension of the first helical tube 130 can be appropriately set according to, for example, the refrigerant capacity.

Although the first helical tube 130 has been described above, its configuration is not particularly limited. For example, the number of first helical tubes 130 can be appropriately set according to the refrigerant capacity, and may be one, or three or more may be provided in parallel. Also, two or more first helical tubes 130 may be connected in series. Also, the size relationship with the second helical tube 140 of each size is not particularly limited.

[Second spiral tube 140]
The second helical tube 140 is arranged downstream of the first helical tube 130 and receives the liquid refrigerant Q3 from the first helical tube 130 . Two second spiral tubes 140 are arranged in parallel in the same manner as the first spiral tube 130 described above. are connected, and a collecting pipe 142 connecting them is also connected to the downstream side. The collection pipe 141 functions as a buffer for smoothly introducing the liquid refrigerant Q3 into the second spiral pipe 140 .

When the liquid refrigerant Q3 from the first spiral tube 130 is introduced into the second spiral tube 140, the liquid refrigerant Q3 is pulled by the second spiral tube 140 to increase its speed and At , the molecules of the refrigerant Q vibrate and rotate, and radiate energy. The liquid refrigerant Q3 is decompressed and expanded by this speed increase and the energy radiation due to the vibration and rotation of the refrigerant molecules, and becomes a low-temperature, low-pressure liquid refrigerant Q4. It should be noted that the energy radiation in the second spiral tube 140 is based on the same principle as in the first spiral tube 130, so the explanation thereof will be omitted.

As described above, in this embodiment, almost 100% of the refrigerant Q is liquefied in the first helical tube 130, but if this is not the case, that is, if gas components remain, the second helical tube 140 The remaining gas component is liquefied by , resulting in almost 100% liquid refrigerant.

The inner diameter of the second helical tube 140 is smaller than the inner diameter of the first helical tube 130 . The inner diameter of the second helical tube 140 is not particularly limited, but can be, for example, about 1 mm to 5 mm. Also, the spiral diameter of the second spiral tube 140 is smaller than the spiral diameter of the first spiral tube 130 . The spiral diameter of the second spiral tube 140 is not particularly limited, but can be, for example, about 10 mm to 30 mm. Also, the second spiral tube 140 is shorter than the first spiral tube 130 . The length (total length) of the second helical tube 140 is not particularly limited, but can be, for example, approximately 500 mm to 1000 mm. Each dimension of the second helical tube 140 can be appropriately set according to, for example, the refrigerant capacity.

Although the second helical tube 140 has been described above, its configuration is not particularly limited. For example, the number of second spiral tubes 140 can be appropriately set according to the refrigerant capacity, and may be one, or three or more may be provided in parallel. Also, two or more second spiral tubes 140 may be connected in series. Also, the size relationship with the first spiral tube 130 of each size is not particularly limited.

The first helical tube 130 and the second helical tube 140 as described above are formed, for example, by the following method. First, a copper tube is prepared, a piano wire is inserted into this copper tube, and the copper tube is squeezed to the outer diameter (thickness) of the piano wire to form a straight tube. Further, the first spiral tube 130 and the second spiral tube 140 are formed by spirally winding this straight tube into a spiral tube.

By twisting the copper tube, spiral grooves (hereinafter also referred to as “spiral grooves”) are formed in the inner walls of the first spiral tube 130 and the second spiral tube 140 . Furthermore, by spirally winding the straight pipe with the spiral groove formed thereon, the outer side of the spiral is pulled in the longitudinal direction as a whole, and the pitch of the spiral groove is widened compared to the straight pipe state. On the contrary, the inside of the spiral is compressed in the longitudinal direction as a whole, and the pitch of the spiral groove becomes narrower than in the straight pipe state. In addition, a "constriction" is formed by twisting the copper pipe in the axial direction during the process of spirally winding the straight pipe. The feeding angle and pitch of the helical grooves, and the formation position and number of constrictions are appropriately set for the first helical tube 130 and the second helical tube 140, respectively.

In this way, the pitch of the spiral groove is different between the outer peripheral side and the inner peripheral side of the first and second spiral tubes 130 and 140, and furthermore, the constriction is formed, so that the first and second Refrigerant molecules vibrate and rotate in the two helical tubes 130 and 140, and have a particularly favorable effect on heat conversion in the first and second helical tubes 130 and 140. FIG. In other words, in the first and second helical tubes 130 and 140, the feeding angle and pitch of the helical grooves, the formation position and number of constrictions, etc. are set so that the refrigerant molecules oscillate and rotate inside them. However, this is just an example, and the configuration and forming method of the first and second spiral tubes 130 and 140 are not particularly limited as long as they can exhibit the above-described functions. Further, instead of the first and second helical tubes 130 and 140, for example, an expansion valve or the like having the same function as these may be used.

[Evaporator 150]
The evaporator 150 is arranged downstream of the second spiral tube 140 and receives the liquid refrigerant Q4 from the second spiral tube 140 . The temperature of the liquid refrigerant Q4 introduced into the evaporator 150 is not particularly limited, but is preferably 0° or lower, which is the freezing temperature of the water W, and is, for example, about -30° to -10°.

As shown in FIG. 2, the evaporator 150 has a helical tube 151 . The helical tube 151 is a long straight tube 152 (circular tube) having a circular cross-sectional shape as shown in FIG. It was formed by In the spiral tube 151, adjacent tubes 152 are in contact with each other. That is, the tube 152 is spirally wound without gaps. However, it is not limited to this, and for example, gaps may be formed between adjacent tubes 152 .

The dimensions of such a tube 152 are not particularly limited, and for example, the number of turns may be about 6 to 10, the inner diameter about 10 mm to 30 mm, the spiral diameter about 100 mm to 200 mm, and the total length about 5 m to 10 m. . Moreover, the cross-sectional shape of the tube 152 is not limited to a circle, and may be, for example, an ellipse, an oval, a polygon, or the like.

A groove 153 extending in the circumferential direction of the pipe 152 is formed in the outer circumference of the pipe 152 . The groove 153 is inclined with respect to the axis of the tube 152 and has a spiral shape extending in the axial direction while rotating in the circumferential direction. The dimensions of the grooves 153 are not particularly limited, and for example, as shown in FIG. It can be about 20°.

Also, as shown in FIG. 5, the evaporator 150 has a double tube 154 in which a spiral tube 151 is arranged. The double pipe 154 has a structure in which an inner pipe 155 and an outer pipe 156, both of which are cylindrical, are concentrically arranged. It is a flow channel. Further, the space S is provided with a spiral tube 151 arranged concentrically with the double tube 154, and the spiral tube 151 prevents the water W from flowing smoothly. That is, the evaporator 150 includes a spiral tube 151, an inner tube 155 arranged inside the spiral tube 151, and an inner tube 155 arranged outside the spiral tube 151. and an outer tube 156 arranged to receive it.

Also, the outer diameter of the inner tube 155 and the inner diameter of the spiral tube 151 are substantially equal, and the outer peripheral surface of the inner tube 155 is in contact with the inner periphery of the spiral tube 151 . Similarly, the inner diameter of the outer tube 156 and the outer diameter of the helical tube 151 are substantially equal, and the inner peripheral surface of the outer tube 156 is in contact with the outer periphery of the helical tube 151 . Therefore, the helical tube 151 is sandwiched between an inner tube 155 located inside and an outer tube 156 located outside.

Further, as shown in FIG. 6, a funnel-shaped guiding portion 157 for guiding the water W to the double pipe 154 is provided on the upstream side of the double pipe 154, and the double pipe 154 is provided on the downstream side. A funnel-shaped recovery part 158 is provided for recovering the water W that has passed through. Therefore, the introduction of the water W into the double pipe 154 and the recovery of the water W from the double pipe 154 can be performed smoothly without stagnation.

In the evaporator 150 having such a configuration, when the water W is introduced into the space S, as shown in FIG. It flows downstream in the space S by repeating movement to the downstream pipe 152 while making several turns around the pipe 152 . In FIG. 7, while rotating along the groove 153 around the n-th pipe 152(n) from the upstream side, it moves to the adjacent pipe 152(n+1) downstream (n+1-th from the upstream side). , rotates along the groove 153 around the tube 152(n+1) and moves to the adjacent tube 152(n+2) on the downstream side (n+2th from the upstream side).

In this way, by rotating the water W along the groove 153 around the pipe 152 and moving it to the pipe 152 on the downstream side in order, the water W passing through the space S and the liquid passing through the spiral pipe 151 are separated from each other. Heat exchange is efficiently performed with the refrigerant Q4, and energy such as heat hidden inside the water W (hereinafter also referred to as “internal energy”) is released at once, thereby instantly deheating the water W ( cooling). To briefly explain this with some speculation, since the refrigerant Q flows in the spiral tube 151 at an angle of about -30° to -10°, the water W flows as described above, and the water molecules As the water molecules vibrate and rotate, a speed difference occurs between the upper and lower sides of the water molecules (refrigerant pipe 151 side and the opposite side), the water molecules are deformed by the speed difference (cracking in an image), and the internal energy of the water molecules is released at once. be. The water W is instantaneously deheated by the release of this internal energy and the heat exchange with the liquid refrigerant Q4.

It should be noted that the water W passes through the space S in about 1/100th of a second, during which heat is instantaneously removed and the temperature drops to about room temperature.

In particular, in the present embodiment, as described above, the adjacent tubes 152 of the spiral tube 151 are in contact with each other. flow can be generated more reliably. In addition, as described above, the inner tube 155 is in contact with the inner periphery of the spiral tube 151, and the outer tube 156 is in contact with the outer periphery of the spiral tube 151, so that the water W can be easily rotated along the groove 153. The above-described flow of water W can be generated more reliably. Further, as described above, by making the grooves 153 helical, the water W can be easily rotated along the grooves 153, and the flow of the water W described above can be generated more reliably. In addition, if the groove 153 is spiral, there is an advantage that the groove 153 can be easily formed by cutting.

The liquid refrigerant Q4 passing through the helical tube 151 becomes low-pressure gas refrigerant Q5 through heat exchange with the water W. Then, the gas refrigerant Q5 is introduced into the compressor 110 and discharged again as the high-temperature and high-pressure gas refrigerant Q1. In the heat removal device 100, the water W can be continuously heat removed (cooled) by repeating the cycle of the refrigerant Q as described above.

<Second embodiment>
Next, a heat removal device 100 according to a second embodiment of the present invention will be described. The heat sink 100 of this embodiment is the same as the heat sink 100 of the first embodiment described above, except that the configuration of the spiral tube 151 is different. Therefore, in the following description, regarding this embodiment, the differences from the first embodiment described above will be mainly described, and the description of the same matters will be omitted. Moreover, in each figure in this embodiment, the same code|symbol is attached|subjected about the structure similar to embodiment mentioned above.

As shown in FIG. 8, in this embodiment, an annular (ring-shaped) groove 153 is formed on the outer circumference of the tube 152 . A plurality of annular grooves 153 are formed side by side at equal intervals along the axial direction of the tube 152 . The spiral tube 151 formed by spirally winding the tube 152 having such a structure can also exhibit the same effect as the first embodiment described above.

In the present embodiment, the plane F including the annular groove 153 is orthogonal to the axis of the tube 152, but is not limited to this, and the plane F is inclined with respect to the axis of the tube 152. good too.

Such a second embodiment can also exhibit the same effect as the first embodiment described above.

<Third Embodiment>
Next, a power generator 200 according to a third embodiment of the invention will be described.

The power generation device 200 shown in FIG. 9 includes a pump unit 210 that pressurizes and sends out water W, a heat removal unit 220 that removes heat from the water W sent out from the pump unit 210, and the water W that has passed through the heat removal unit 220. It is driven by the collision of the storage tank 230 to store, the pressurization unit 240 that pressurizes the water W in the storage tank 230 by filling the storage tank 230 with nitrogen _N2 , and the water W discharged from the storage tank 230. It has a power generation unit 250 , a pipe 260 connecting these parts and through which water W circulates, and check valves 270 installed at several points along the pipe 260 . In such a power generator 200, by driving the pump unit 210, the water W circulates in the direction of the arrow A in the pipe 260, whereby the power generation unit 250 generates power.

It should be noted that the liquid (from which heat is to be removed) that is circulated through the pipe 260 is not limited to water W. However, by using water W, the power generation cost can be reduced.

The pump unit 210 has two pressure pumps 211, 212 arranged in parallel. By connecting the two pressure pumps 211 and 212 in parallel in this way, the maintenance of the pump unit 210 is facilitated. For example, if the pressure pumps 211 and 212 are driven at an output of about 50% each during normal times, and the pressure pump 212 is driven at 100% during maintenance or replacement of the pressure pump 211, it is possible to drive the pressure pumps 211 and 212 at 100% during maintenance. becomes. Therefore, it is preferable to use the pressure pumps 211 and 212 that have the ability to pressurize the water W up to the required pressure with about 50% drive.

Such pressure pumps 211 and 212 are multi-stage centrifugal pumps that pressurize water W using centrifugal force generated by rotation of impellers. According to the multistage volute pump, since it is possible to apply spiral rotation (centrifugal force) to the molecules of the water W, it is well compatible with this system. However, the pressure pumps 211 and 212 are not particularly limited. Also, the number of pressure pumps included in the pump unit 210 is not limited to two, and may be one or three or more.

The water W sent out from the pump unit 210 is introduced into the heat removal unit 220 and heat is removed. Evaporation of the water W is prevented by deheating the water W heated by the pressurization by the pump unit 210 by the heat removal unit 220, and the power generation capacity of the power generation device 200 can be prevented from decreasing.

The heat sink unit 220 has two heat sinks 221 and 222 arranged in parallel. The heat removal device 221 is connected to the pressure pump 211, receives the high-pressure water W discharged from the pressure pump 211, and removes heat from the water W. Similarly, the heat removal device 222 is connected to the pressure pump 212, receives the high-pressure water W discharged from the pressure pump 212, and removes heat from the water W. In this embodiment, the heat sink 100 of the first embodiment is used as the heat sinks 221 and 222, and water is introduced into the space S from the pressure pumps 211 and 212. ing. As the water W flows through the space S, heat is removed. As a result, the water W can be instantly deheated, and the evaporation of the water W caused by the temperature rise can be prevented more reliably.

The storage tank 230 stores the water W from which the heat is removed by the heat removal unit 220 . The storage tank 230 has a tank main body 231 and a floating lid 232 arranged in the tank main body 231 so as to be movable up and down. Therefore, the inside of the storage tank 230 is partitioned into a lower space S1 positioned below the floating lid 232 and an upper space S2 positioned above the floating lid 232 . Water W is introduced and stored in the lower space S1, and gas is introduced from the pressure unit 240 into the upper space S2. The capacity of the water W stored in the storage tank 230 is not particularly limited, but is, for example, approximately 300 to 500 liters.

The pressurization unit 240 has a nitrogen generator 241 that generates gaseous nitrogen (N ₂ ) and a compressor 242 that introduces the nitrogen generated by the nitrogen generator 241 into the upper space S2 of the storage tank 230 . By introducing nitrogen into the upper space S2 by the compressor 242, the floating lid 232 is urged downward and the water W stored in the lower space S1 is pressurized. By using nitrogen to pressurize the water W, the safety of the power generator 200 can be increased and the cost can be reduced.

However, the gas introduced into the storage tank 230 is not limited to nitrogen, and may be, for example, the atmosphere (air). In this case, since the pressurizing unit 240 is substantially composed only of the compressor 242, the size and cost of the power generator 200 can be reduced. Further, for example, when nitrogen is used, a cylinder filled with nitrogen can be used instead of the nitrogen generator 241 .

The power generation unit 250 has a generator 254 and a power generator 251 that generates power for driving the generator 254 . In addition, the power generation unit 251 has a water wheel 252 (rotated body) that rotates when it collides with the water W discharged from the storage tank 230, and an output shaft 253 that outputs the rotation of the water wheel 252. Output shaft 253 is connected to generator 254 . Therefore, as the water wheel 252 rotates, power is generated by the generator 254 .

Note that the configuration of the power generation unit 251 is not limited to the configuration described above, and may be any configuration as long as the power of the water W can be used to drive the generator 254 . In the illustrated configuration, the output shaft 253 and the generator 254 are directly connected, but the invention is not limited to this. etc. may intervene.

Also, the configuration of the generator 254 is not particularly limited as long as it can exhibit its function. For example, an alternator having a pair of coils and a magnet placed between the pair of coils and connected to the output shaft 253, wherein rotation of the output shaft 253 causes the magnet to rotate between the pair of coils. Conversely, it has a pair of magnets and a coil that is arranged between the pair of magnets and connected to the output shaft 253, and the rotation of the output shaft 253 rotates the coil to the pair of magnets. It may be a DC generator rotated between magnets. Moreover, the generator of any structure other than these may be used.

In addition, the power generator 251 further has a recovery tank 255 that recovers the water W used for rotating the water turbine 252 . Water W collected in the collection tank 255 is sent to the pump unit 210 .

The power generation device 200 configured as described above is driven as follows. In the power generation device 200, the pump unit 210 is driven to pump water W at a pressure of about 3 to 7 atmospheres from the pump unit 210 at a flow rate of 5000 cc to 10000 cc/sec. The water W sent out from the pump unit 210 is introduced into the heat removal unit 220 and instantly deheated (cooled) to approximately room temperature. The water W cooled by the heat removal unit 220 is then introduced into the lower space S1 of the storage tank 230 . The water W stored in the storage tank 230 is deheated by being mixed with the water W newly introduced from the heat removal unit 220, so the water W in the storage tank 230 is maintained at about room temperature. In particular, by using multi-stage centrifugal pumps as the pressure pumps 211 and 211, the water W is caused to swirl, and the water molecules are caused to oscillate and rotate in the heat sinks 221 and 222. becomes easy to mix, and the above-mentioned effect becomes more remarkable.

Nitrogen _N2 is introduced into the upper space S2 of the storage tank 230 from the pressurizing unit 240, and the pressure of the nitrogen _N2 in the storage tank 230 is maintained at about 3 to 7 atmospheres. Therefore, the water W of about 3 to 7 atmospheres is discharged from the storage tank 230 . The water W discharged from the storage tank 230 is discharged toward the water turbine 252 after being guided directly above the water turbine 252 by the pipe 260 . The water W discharged toward the water wheel 252 collides with the water wheel 252, thereby causing the water wheel 252 to rotate. As the water wheel 252 rotates, the power generator 254 starts to generate power.

Here, the swirling flow of water W and the vibratory rotation of water molecules generated by the pressure pumps 211 and 212 and the heat sinks 221 and 222 are maintained until they collide with the water turbine 252 via the storage tank 230 . Then, when the water W with the swirling flow or the vibrating rotation collides with the water wheel 252, the pressure of the water W instantly drops to the original pressure of the water W. That is, the pressurization by nitrogen N2 is released. Therefore, the water W that collides with the water turbine 252 and is recovered in the recovery tank 255 is approximately atmospheric pressure/16°C. By creating a large pressure difference between the upstream side and the downstream side of the water turbine 252 in this manner, the water turbine 252 can be rotated at a higher speed, thereby improving power generation efficiency.

The water W recovered in the recovery tank 255 is introduced into the pump unit 210 , pressurized again by the pump unit 210 and sent out toward the heat removal unit 220 . In the power generator 200, power generation can be continued by circulating the water W in this manner. In particular, by providing the heat sinks 221 and 222, the water W can be maintained at about room temperature, and evaporation/vaporization of the water W can be prevented for a long period of time. In other words, there is no need to periodically stop the operation in order to prevent the temperature of the water W from rising, and continuous operation becomes possible. Therefore, the power generator 200 can exhibit excellent power generation efficiency.

The driving of the power generator 200 has been described above, but the above is just an example, and for example, the temperature and pressure of the water W in each part, the capacity of the storage tank 230, and the like are not particularly limited.

Refrigerant Q is passed through the pipe 151, and water W (to be heat removed) is passed between the inner pipe 155 and the outer pipe 156, thereby performing heat exchange between the refrigerant Q and the water W, and deheating the water W. . According to such a configuration, when the water W passes between the inner tube 155 and the outer tube 156, the internal energy of water molecules is released at once. Therefore, the heat of the water W can be instantaneously removed. Therefore, its industrial applicability is great.
