Description

Technical Field

[0001] The present invention relates to the technical field of heaters, and particularly to a semiconductor thermoelectric integrated geothermal heater. Background Art

[0002] Semiconductor thermoelectric heat collection is to concentrate the low and medium temperature heat energy in groundwater into high temperature heat energy that can be utilized. According to the Peltier effect: when any two different metal conductors are connected and direct current is passed through both ends of the conductor, in addition to Joule heat, there is excess heat absorbed or released at the joint depending on the direction of the current. According to this principle, a semiconductor thermoelectric plate composed of multiple series- and parallel-connected semiconductor thermoelectric elements can transfer the heat on one side to the other side.

[0003] Indoor heating mainly uses coal-fired, oil-fired boilers and electric heaters. Coal-fired and oil-fired boiler heating consumes a large amount of non-renewable resources and pollutes the environment at the same time. When using an electric heater for heating, only a small part of the heat is utilized, and in this process, high-quality electric energy is directly converted into heat, resulting in high usage costs and low energy efficiency.

[0004] Therefore, a semiconductor thermoelectric integrated geothermal heater is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a semiconductor thermoelectric integrated geothermal heater, which improves the chaos degree of the fluid inside the heat dissipation pipe through a fixing rod, enables multiple heat dissipation fins to be evenly heated, thereby improving the heating efficiency of the heater, further efficiently heating the indoor environment, and making it difficult for water scale to accumulate inside the water conduction pipe, thereby achieving the effect of reducing water scale, so as to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution:

[0007] A semiconductor thermoelectric integrated geothermal heater, including a semiconductor thermoelectric sheet, a hot water tank fixedly installed on one side of the hot end of the semiconductor thermoelectric sheet, a cold water tank fixedly installed on one side of the cold end of the semiconductor thermoelectric sheet, both ends of the hot water tank and the cold water tank are respectively connected and communicated through two water conduction pipes, two water pumps for driving the water bodies inside the two water conduction pipes to flow respectively, a heat dissipation pipe fixedly installed in the water conduction pipe inside the hot water tank, a plurality of heat dissipation fins are fixedly installed at equal intervals on the outside of the heat dissipation pipe, and a plurality of vertically inserted fixing rods are also fixedly installed inside the heat dissipation pipe.

[0008] When the heater is working, the controller supplies power to the semiconductor thermoelectric chip and two water pumps. The two water pumps can drive the water in the hot water tank and the low-temperature water underground to circulate respectively. When the semiconductor thermoelectric chip is energized, it can concentrate the low-temperature heat energy obtained from the water at the cold end to the hot end, raising the temperature of the water in the hot water tank. After heating in the heat dissipation pipe and flowing back, the water with some heat removed in the cold water tank is discharged back underground. When the hot water circulates through the heat dissipation pipe, it will impact multiple fixed rods inserted in the pipe. Subsequently, two rows of line vortices with opposite rotation directions and arranged in a regular double row will periodically shed on both sides of the fixed rods. At the beginning, these two rows of line vortices move forward while maintaining their own motions. Then they interfere with each other, attract each other, and the interference becomes greater and greater. After non-linear action, a Karman vortex street is formed, thereby increasing the chaos degree of the fluid inside the heat dissipation pipe, enabling multiple heat dissipation fins to be evenly heated, and thus improving the heating efficiency of the heater.

[0009] Preferably, a rotating shaft is rotatably installed at one end of the semiconductor thermoelectric chip. A disc is fixedly installed outside the rotating shaft. An annular cavity is formed inside the disc. A plurality of expansion balls that expand when heated are fixedly installed at equal intervals inside the annular cavity. A counterweight ball is fixedly installed inside each expansion ball.

[0010] When the heater is working, there is a large temperature difference between the outside of the hot water tank and the cold water tank. The area of the front end of the disc close to the hot water tank has a higher temperature, and the area of the rear end of the disc close to the cold water tank has a lower temperature. The expansion balls at the front end of the disc expand when heated, causing the expansion balls to squeeze towards the area of the cold water tank. As a result, the counterweight balls inside the expansion balls move towards the area of the cold water tank, making the gravity at the rear side of the disc greater than that at the front side, breaking the original balance and driving the disc to rotate counterclockwise. Then, the expansion balls with lower temperature at the rear end of the disc are turned towards the area of the hot water tank to be heated, and the hotter expansion balls are squeezed towards the area of the cold water tank for cooling. In this way, the disc and the rotating shaft will continue to rotate, thereby providing power for the rotation of the disc.

[0011] Preferably, the disc is made of copper.

[0012] Copper has good thermal conductivity, and thus can quickly transfer the heat of the hot water tank and the cold water tank to the inside of the annular cavity.

[0013] Preferably, a rectangular plate is fixedly installed on one side of the hot water tank. A plurality of rectangular cavities are formed at equal intervals inside the rectangular plate. A transmission rod is rotatably installed inside the plurality of rectangular cavities together. A first transmission wheel is also fixedly installed on the outer edge of the rotating shaft. One end of the transmission rod extends outside the rectangular plate and is fixedly installed with a second transmission wheel. The first transmission wheel and the second transmission wheel are connected by a transmission belt.

[0014] After the disc rotates, the rotating shaft drives the first transmission wheel to rotate, and then drives the transmission rod inside the second transmission wheel to rotate through the transmission belt, thereby driving the transmission rod to rotate continuously and providing power for the subsequent process.

[0015] Preferably, a guide rod is rotatably installed inside each of the rectangular cavities. A first bevel gear is fixedly installed on the outer edge of the transmission rod inside a plurality of the rectangular cavities respectively. A second bevel gear is fixedly installed at one end of the guide rod inside the rectangular cavity. The first bevel gear meshes with the second bevel gear. The other end of the guide rod extends outside the rectangular plate and is fixedly installed with a fan.

[0016] After the transmission rod rotates, it drives the first bevel gears inside a plurality of rectangular cavities to rotate. Subsequently, the plurality of first bevel gears drive a plurality of guide rods to rotate respectively through a plurality of second bevel gears. Then, the plurality of guide rods drive a plurality of fans to rotate, thereby driving the gas to flow and blowing towards the heat sink. Subsequently, the heat inside the heat sink is blown away, thereby heating the room and improving the heating efficiency of the heater for the room.

[0017] Preferably, the diameter ratio of the first transmission wheel to the second transmission wheel is 7:1.

[0018] Since the diameter of the first transmission wheel is much larger than that of the second transmission wheel, the rotational speed at the output end of the first transmission wheel becomes smaller, but the torque increases, and it can more easily drive the second transmission wheel to rotate, thus avoiding the situation where the transmission rod cannot rotate.

[0019] Preferably, the shape of the transmission belt is a "Möbius strip" shape.

[0020] The transmission belt with a "Möbius strip" structure can not only increase the effective friction area of the belt, but also distribute the stress to "both sides", thereby doubling the service life.

[0021] Preferably, a plurality of magnets are fixedly installed at equal intervals on the inner edge of the disc.

[0022] After the disc rotates, the plurality of magnets can rotate in the vertical direction of the two water pipes. The magnetic field inside the magnets magnetizes the water body inside the water pipes. After the water body is magnetized, the covalent bond angle changes from 105° to 103°, and the water changes from the original 13 - 18 large molecular clusters to 5 - 6 small molecular clusters. The water permeability and solubility are significantly improved. CaCO3 and MgCO3 in the water dissolve and transform into softer Ca(HCO3)2 and Mg(HCO3)2, making it not easy to accumulate inside the water pipes, thereby achieving the effect of reducing scale.

[0023] Preferably, a controller is provided outside the hot water tank, and the semiconductor thermoelectric cooler and the two water pumps are electrically connected to the controller.

[0024] Preferably, the water guide pipes at both ends of the cold water tank are inserted 10 m underground.

[0025] Due to the relatively low temperature underground, the water guide pipes at both ends of the cold water tank can be quickly cooled, so that the cold end of the semiconductor thermoelectric sheet can continuously contact with cold water, thereby improving the working efficiency of the heater.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. When the heater is working, the multiple fixing rods inside the heat dissipation pipe can increase the chaos degree of the fluid inside the heat dissipation pipe, so that the multiple heat dissipation fins can be uniformly heated, thereby improving the heating efficiency of the heater.

[0028] 2. When the heater is working, it can drive multiple fans to rotate, thereby driving the gas to flow and blowing towards the heat dissipation fins, and then blowing the heat inside the heat dissipation fins away, thereby heating the room and improving the heating efficiency of the heater for the room.

[0029] 3. After the disc rotates, it can prevent scale from easily accumulating inside the water guide pipe, thereby achieving the effect of reducing scale. BRIEF DESCRIPTION OF THE DRAWINGS

Specific Embodiment

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Please refer to Figures 1 to 7 , the present invention provides a semiconductor thermoelectric geothermal heater, and the technical solution is as follows:

[0040] A semiconductor thermoelectric geothermal heater includes a semiconductor thermoelectric chip 1, a hot water tank 2 fixedly installed on one side of the hot end of the semiconductor thermoelectric chip 1, a cold water tank 3 fixedly installed on one side of the cold end of the semiconductor thermoelectric chip 1. The two ends of the hot water tank 2 and the cold water tank 3 are respectively connected and communicated through two water pipes 5. Two water pumps 4 are used to drive the water bodies inside the two water pipes 5 to flow respectively. A heat dissipation pipe 6 is fixedly installed in the water pipe 5 inside the hot water tank 2. A plurality of heat dissipation fins 7 are fixedly installed at equal intervals outside the heat dissipation pipe 6. A plurality of vertically inserted fixing rods 8 are also fixedly installed inside the heat dissipation pipe 6.

[0041] When the heater is working, the semiconductor thermoelectric chip 1 and the two water pumps 4 are powered by a controller. The two water pumps 4 can drive the water body inside the hot water tank 2 and the low-temperature water body underground to circulate respectively. When the semiconductor thermoelectric chip 1 is powered on, it can concentrate the low-temperature heat energy obtained from the water at the cold end to the hot end, so that the water temperature in the hot water tank 2 rises, returns after heating in the heat dissipation pipe 6, and the water with part of the heat removed in the cold water tank 3 is discharged back underground. When the hot water circulates through the heat dissipation pipe 6, it will impact the plurality of fixing rods 8 inserted in the pipe. Subsequently, two rows of vortices with opposite rotation directions and arranged in a regular double row will periodically fall off on both sides of the fixing rods 8. At the beginning, these two rows of vortices maintain their own movements forward respectively. Then they interfere with each other, attract each other, and the interference becomes greater and greater. After non-linear action, a Karman vortex street (as shown in Figure 5 ) is formed, thereby increasing the chaos degree of the fluid inside the heat dissipation pipe 6, enabling the plurality of heat dissipation fins 7 to be evenly heated, and thus improving the heating efficiency of the heater.

[0042] As an embodiment of the present invention, referring to Figure 6 , a rotating shaft 10 is rotatably installed at one end of the semiconductor thermoelectric chip 1. A disc 11 is fixedly installed outside the rotating shaft 10. An annular cavity 12 is formed inside the disc 11. A plurality of expansion balls 13 that expand when heated are fixedly installed at equal intervals inside the annular cavity 12. A counterweight ball 14 is fixedly installed inside each expansion ball 13.

[0043] When the heater is working, the temperature difference between the hot water tank 2 and the outside of the cold water tank 3 is large. The temperature of the area near the hot water tank 2 at the front end of the disk 11 is higher, and the temperature of the area near the cold water tank 3 at the rear end of the disk 11 is lower. The expansion ball 13 at the front end of the disk 11 expands due to the heat, so that the expansion ball 13 is squeezed toward the area of ​​the cold water tank 3, so that the counterweight ball 14 inside the expansion ball 13 moves toward the area of ​​the cold water tank 3, so that the gravity on the rear side of the disk 11 is greater than the gravity on the front side, breaking the original balance and driving the disk 11 to rotate counterclockwise, and then the expansion ball 13 with a lower temperature at the rear end of the disk 11 is turned to the area of ​​the hot water tank 2 for heating, while the hotter expansion ball 13 is squeezed to the area of ​​the cold water tank 3 for cooling. This reciprocating motion will cause the disk 11 and the rotating shaft 10 to rotate continuously, thereby providing power for the rotation of the disk 11.

[0044] As an embodiment of the present invention, refer to Figure 6 The material of the disk 11 is metal copper.

[0045] Metal copper has good thermal conductivity, and can quickly transfer the heat of the hot water tank 2 and the cold water tank 3 to the inside of the annular cavity 12 .

[0046] As an embodiment of the present invention, refer to Figures 6 - 7 A rectangular plate 9 is fixedly installed on one side of the hot water tank 2, and a plurality of rectangular cavities 19 are opened at equal intervals inside the rectangular plate 9. A transmission rod 15 is installed inside the plurality of rectangular cavities 19 for common rotation. A first transmission wheel 16 is also fixedly installed on the outer edge of the rotating shaft 10. One end of the transmission rod 15 extends to the outside of the rectangular plate 9 and is fixedly installed with a second transmission wheel 17. The first transmission wheel 16 and the second transmission wheel 17 are connected through a transmission belt 18.

[0047] After the disc 11 rotates, the rotating shaft 10 drives the first transmission wheel 16 to rotate, and then drives the transmission rod 15 inside the second transmission wheel 17 to rotate through the transmission belt 18, thereby driving the transmission rod 15 to rotate continuously to provide power for the subsequent operation.

[0048] As an embodiment of the present invention, refer to Figures 1 - 3 A guide rod 22 is rotatably installed inside each rectangular cavity 19, and the outer edge of the transmission rod 15 is fixedly installed with a first bevel gear 20 inside the multiple rectangular cavities 19, one end of the guide rod 22 is fixedly installed with a second bevel gear 21 inside the rectangular cavity 19, the first bevel gear 20 is meshed with the second bevel gear 21, and the other end of the guide rod 22 extends to the outside of the rectangular plate 9 and is fixedly installed with a fan 23.

[0049] After the drive rod 15 rotates, it will drive the first bevel gears 20 inside the multiple rectangular cavities 19 to rotate. Subsequently, the multiple first bevel gears 20 will respectively drive the multiple guide rods 22 to rotate through the multiple second bevel gears 21. Then, the multiple guide rods 22 will drive the multiple fans 23 to rotate, thereby driving the gas to flow and blowing towards the heat sink 7. Subsequently, the heat inside the heat sink 7 will be blown away, thereby heating the room and improving the heating efficiency of the heater for the room.

[0050] As an implementation manner of the present invention, referring to Figure 7 , the diameter ratio of the first transmission wheel 16 to the second transmission wheel 17 is 7:1.

[0051] Since the diameter of the first transmission wheel 16 is much larger than that of the second transmission wheel 17, the rotational speed at the output end of the first transmission wheel 16 becomes smaller, but the torque increases, and it can more easily drive the second transmission wheel 17 to rotate, thereby avoiding the situation where the drive rod 15 cannot rotate.

[0052] As an implementation manner of the present invention, referring to Figure 7 , the shape of the transmission belt 18 is in the shape of a "Möbius strip".

[0053] The transmission belt 18 with a "Möbius strip" structure can not only increase the effective friction area of the belt, but also distribute the stress to "both sides", thereby doubling the service life.

[0054] As an implementation manner of the present invention, referring to Figure 6 , a plurality of magnets 24 are also fixedly installed at equal intervals on the inner edge of the disc 11.

[0055] After the disc 11 rotates, the multiple magnets 24 can rotate in the vertical direction of the two water pipes 5. The magnetic field inside the magnets 24 will magnetize the water body inside the water pipes 5. After the water body is magnetized, the covalent bond angle changes from 105° to 103°, and the water changes from the original 13 - 18 large molecular clusters to 5 - 6 small molecular clusters. The permeability and solubility of the water are significantly improved, and the CaCO3 and MgCO3 in the water are dissolved and converted into softer Ca(HCO3)2 and Mg(HCO3)2, making it not easy to accumulate inside the water pipes 5, thereby achieving the effect of reducing scale.

[0056] As an implementation manner of the present invention, referring to Figure 1 , a controller is provided outside the hot water tank 2, and the semiconductor thermoelectric chip 1 and the two water pumps 4 are both electrically connected to the controller.

[0057] As an implementation manner of the present invention, referring to Figure 1 , the water pipes 5 at both ends of the cold water tank 3 are inserted 10 m underground.

[0058] Due to the relatively low temperature underground, the water pipes 5 at both ends of the cold water tank 3 can be quickly cooled, so that the cold end of the semiconductor thermoelectric chip 1 can continuously contact with cold water, thereby improving the working efficiency of the heater.

[0059] Working principle: When the heater is working, the controller supplies power to the semiconductor thermoelectric chip 1 and the two water pumps 4. The two water pumps 4 can drive the water in the hot water tank 2 and the low-temperature water underground to circulate respectively. When the semiconductor thermoelectric chip 1 is energized, it can concentrate the low-temperature heat energy obtained by the cold end from the water to the hot end, raising the temperature of the water in the hot water tank 2. After heating in the heat dissipation pipe 6 and then flowing back, the water with some heat removed in the cold water tank 3 is discharged back underground. When the hot water circulates through the heat dissipation pipe 6, it will impact multiple fixed rods 8 inserted in the pipe. Subsequently, two rows of line vortices with opposite rotation directions and arranged in a regular double row will periodically shed on both sides of the fixed rod 8. At the beginning, these two rows of line vortices move forward while maintaining their own motions. Then they interfere with each other, attract each other, and the interference becomes greater and greater. After non-linear action, a Karman vortex street is formed, thereby increasing the chaos degree of the fluid inside the heat dissipation pipe 6, enabling multiple heat dissipation fins 7 to be evenly heated, and thus improving the heating efficiency of the heater. When the heater is working, there is a large temperature difference between the outside of the hot water tank 2 and the cold water tank 3. The area near the front end of the disc 11 close to the hot water tank 2 has a higher temperature, and the area near the rear end of the disc 11 close to the cold water tank 3 has a lower temperature. The expansion ball 13 at the front end of the disc 11 expands when heated, causing the expansion ball 13 to squeeze towards the area of the cold water tank 3. As a result, the counterweight ball 14 inside the expansion ball 13 moves towards the area of the cold water tank 3, making the gravity at the rear side of the disc 11 greater than that at the front side, breaking the original balance and driving the disc 11 to rotate counterclockwise. Then, the expansion ball 13 with a lower temperature at the rear end of the disc 11 is turned towards the area of the hot water tank 2 to be heated, while the hotter expansion ball 13 is squeezed towards the area of the cold water tank 3 for cooling. This process is repeated, causing the disc 11 and the rotating shaft 10 to continuously rotate, thereby providing power for the rotation of the disc 11. After the disc 11 rotates, the rotating shaft 10 drives the first transmission wheel 16 to rotate, and then drives the transmission rod 15 inside the second transmission wheel 17 to rotate through the transmission belt 18, and thus can drive the transmission rod 15 to continuously rotate. After the transmission rod 15 rotates, it drives the first bevel gears 20 inside multiple rectangular cavities 19 to rotate. Subsequently, multiple first bevel gears 20 drive multiple guide rods 22 to rotate respectively through multiple second bevel gears 21. Then, multiple guide rods 22 drive multiple fans 23 to rotate, thereby driving the air to flow and blowing towards the heat dissipation fins 7. Subsequently, the heat inside the heat dissipation fins 7 is blown away, thereby heating the room and improving the heating efficiency of the heater for the room. After the disc 11 rotates, multiple magnets 24 can rotate in the vertical direction of the two water pipes 5. The magnetic field inside the magnets 24 magnetizes the water body inside the water pipes 5. After the water body is magnetized, the covalent bond angle changes from 105° to 103°, and the water changes from the original 13 - 18 large molecular clusters to 5 - 6 small molecular clusters. The permeability and solubility of the water are significantly improved. CaCO3 and MgCO3 in the water are dissolved and transformed into softer Ca(HCO3)2 and Mg(HCO3)2, making it not easy to accumulate inside the water pipes 5.Furthermore, the effect of reducing water scale is achieved.

[0060] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
