Description

Technical Field

[0001] This invention belongs to the field of spiral flow technology, and particularly relates to a device for extracting cold and hot energy using spiral water flow. Background Technology

[0002] Spiral flow, as a flow form with a rotating flow field, involves both axial and tangential velocities, with the tangential velocity playing the most significant role. Its notable characteristic is a slow tangential velocity at the center and a fast tangential velocity at the periphery. When a straight-flowing water pipe needs to extract heat or cold, because it only contacts the heat or cold source on one side, the absorbed energy is limited and cannot be evenly distributed to the water at a greater distance. This results in insufficient and uneven heating of the water, leading to insignificant heating or cooling effects.

[0003] Existing methods for extracting heat or cold from refrigerants use direct current (DC) flow through pipes, resulting in insufficient energy absorption, ineffective performance, and wasted energy. The purpose of this invention is to transform DC flow into a spiral flow, enabling full energy absorption and achieving high efficiency, energy saving, and environmental friendliness. Summary of the Invention

[0004] The purpose of this invention is to provide a device for extracting hot and cold energy using spiral water flow, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a device for extracting hot and cold energy using spiral water flow, comprising a heat exchange pipe, a heat transfer tube at the center of the heat exchange pipe, a flow guiding component disposed on the pipe wall, and a heat conducting component disposed on the outer periphery of the heat transfer tube, characterized in that: the flow guiding component comprises multiple sets of guide vanes fixed around the periphery of the heat exchange pipe, the guide vanes being perpendicular to the inner wall of the heat exchange pipe and inclined to the pipe wall, the distance between two adjacent guide vanes being 1 / 4 of the pipe diameter, and the width of the guide vanes being 1 / 3 of the inner diameter of the heat exchange pipe. The heat-conducting component includes multiple sets of heat-conducting blocks fixed to the outer periphery of the heat transfer tube. A flow rate test sensor for testing the water flow velocity on the surface of the flow guide plate is provided on one side of the flow guide plate. A water inlet pipe is provided on one side of the heat exchange pipe, and a booster pump is provided on one side of the water inlet pipe. A pressure test sensor is provided on the inner wall of the heat exchange pipe. The pressure test sensor is fixedly connected to the heat exchange pipe. A PLC controller is provided on the outer side of the heat exchange pipe. The PLC controller contains a control module, a calculation module, and an operation module. The internal modules of the PLC controller are electrically connected to the flow rate test sensor and the pressure test sensor.

[0006] As a further aspect of the present invention, the inclination angle between the guide vane and the wall of the heat exchange pipe is 45 degrees.

[0007] As a further embodiment of the present invention: the two intersecting guide vanes are snapped together.

[0008] As a further aspect of the present invention, the guide vane is provided with multiple sets of guide grooves on the side near the heat transfer tube.

[0009] As a further embodiment of the present invention: the guide plate is made of aluminum alloy, and the outer periphery of the guide plate is coated with a waterproof material, which is acrylic polyurethane paint.

[0010] As a further aspect of the present invention: the heat-conducting block is made of aluminum alloy, and the cross-section of the heat-conducting block is triangular.

[0011] As a further embodiment of the present invention: a sealing sleeve is fixedly provided on the outside of the contact part between the heat exchange pipe and the water inlet pipe, and the heat transfer pipe passes through the sealing sleeve.

[0012] As a further embodiment of the present invention, a waterproof gasket is fixedly provided at the contact point between the sealing sleeve and the heat transfer tube.

[0013] As a further embodiment of the present invention, the controller is electrically connected to the booster pump.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention solves the problem that existing methods of extracting heat from cold and hot media, which use direct current through pipes, result in insufficient energy absorption, poor performance, and wasted energy. This is achieved by using heat exchange pipes, heat transfer pipes, flow guiding components, and heat conducting components in combination.

[0015] The heat source and cold source flow through heat transfer tubes, while the heat exchange fluid flows through heat exchange pipes. The guide vanes change the flow path of the heat exchange fluid from a direct current to a spiral flow, increasing the fluid's velocity and facilitating faster heat exchange between the heat source and cold source within the heat transfer tubes. The heat-conducting blocks increase the contact area between the heat transfer tubes and the heat exchange fluid, further accelerating heat exchange and ensuring full energy absorption, resulting in high efficiency, energy saving, and environmental friendliness. When the heat exchange channel becomes blocked, the flow rate sensor on the guide vane receives a signal and transmits it to the controller. The controller's calculation module performs calculations, and the operation module then executes the process. Finally, the control module controls the booster pump, which pressurizes the fluid in the heat exchange pipes to clear the blockage. When the pressure inside the heat exchange pipes becomes too high, the pressure sensor detects a signal and transmits it to the controller. The controller's calculation module performs calculations, and the operation module then executes the process. Finally, the control module controls the booster pump, which shuts down to reduce the pressure inside the heat exchange pipes.

[0016] The inclination angle between the guide vane and the wall of the heat exchange pipe is 45 degrees. The guide vane extends at a certain angle to the direction of water flow. In this way, the water flow entering the heat exchange pipe from the opening will form a spiral motion under the combined action of the moment of momentum around the axis of the heat exchange pipe and the water level difference along the axis of the heat exchange pipe, which enhances the heat exchange of the heat exchange liquid to the heat source in the heat transfer pipe.

[0017] The intersecting guide vanes ensure that the flow channel of the heat exchange liquid is spiral-shaped, preventing flow obstruction and dead zones, and improving flow efficiency.

[0018] Creating flow channels on the surface of the guide vanes can increase the velocity of the heat exchange liquid as it flows across the surface of the guide vanes, thereby enhancing the heat exchange rate.

[0019] The guide vane is made of aluminum alloy and coated with a waterproof material, which is acrylic polyurethane paint. The aluminum alloy material has high strength, which can prevent the guide vane from breaking due to excessive water pressure. At the same time, the acrylic polyurethane paint on the outer periphery of the guide vane can improve the waterproof performance of the guide vane, prevent the heat exchange liquid from corroding the aluminum alloy, and extend the service life of the guide vane.

[0020] The heat-conducting block is made of aluminum alloy and has a triangular cross-section. The heat-conducting block can improve the heat exchange efficiency of the heat transfer tube. At the same time, the triangular cross-section of the heat-conducting block can increase the contact area between the heat transfer tube and the heat exchange liquid, thereby improving the heat exchange efficiency.

[0021] A sealing sleeve is fixed on the outside of the contact area between the heat exchange pipe and the inlet pipe. The heat transfer pipe passes through the sealing sleeve. The sealing sleeve allows the booster pump to apply pressure to the heat exchange pipe, thereby increasing the flow rate of the internal heat exchange liquid and improving the heat exchange efficiency.

[0022] A waterproof gasket is fixed at the contact point between the sealing sleeve and the heat transfer tube to prevent water leakage at the contact point and to prevent water seepage caused by the pressure applied to the sealing sleeve by the booster pump during operation, which would affect the heat exchange efficiency.

[0023] The controller is electrically connected to the booster pump, and the booster pump can be switched on and off by the controller, thus improving its efficiency. Attached Figure Description

[0026] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0027] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1 to 6 As shown in the figure, an embodiment of the present invention provides a device for extracting hot and cold energy using spiral water flow, comprising a heat exchange pipe 1, a heat transfer pipe 2 at the center of the heat exchange pipe 1, a flow guiding component disposed on the wall of the heat exchange pipe 1, and a heat conducting component disposed on the outer periphery of the heat transfer pipe 2. The device is characterized in that: the flow guiding component includes multiple sets of guide vanes 4 fixed around the inner periphery of the heat exchange pipe 1; the guide vanes 4 are perpendicular to the inner wall of the heat exchange pipe 1 and are inclined to the wall; the distance between two adjacent guide vanes 4 is 1 / 4 of the pipe diameter; the width of the guide vanes 4 is 1 / 3 of the inner diameter of the heat exchange pipe 1; and the heat conducting component includes components fixed to the heat transfer pipe. 2. Multiple sets of heat-conducting blocks 5 on the outer periphery. A flow rate test sensor 21 for testing the water flow velocity on the surface of the flow rate test plate 4 is provided on one side of the flow rate test plate 4. A water inlet pipe 22 is provided on one side of the heat exchange pipe 1. A booster pump 23 is provided on one side of the water inlet pipe 22. A pressure test sensor 31 is provided on the inner wall of the heat exchange pipe 1. The pressure test sensor 31 is fixedly connected to the heat exchange pipe 1. A PLC controller 3 is provided on the outer side of the heat exchange pipe 1. The PLC controller 3 is provided with a control module, a calculation module and an operation module. The internal modules of the PLC controller 3 are electrically connected to the flow rate test sensor 21 and the pressure test sensor 31.

[0029] refer to Figure 6 The angle of inclination between the guide vane 4 and the wall of the heat exchange pipe 1 is 45 degrees.

[0030] The above scheme is adopted: the heat source and cold source flow through heat transfer tube 2, and the heat exchange liquid flows through heat exchange pipe 1. The guide vane 4 changes the flow path of the heat exchange liquid through heat exchange pipe 1 from a direct current to a spiral flow, increasing the flow velocity of the heat exchange liquid and facilitating faster heat exchange between the heat source and cold source within heat transfer tube 2. The heat-conducting block 5 increases the contact area between heat transfer tube 2 and the heat exchange liquid, facilitating faster heat exchange between the heat source and cold source inside heat transfer tube 2, ensuring full energy absorption, and thus achieving high efficiency, energy saving, and environmental protection. When the heat conduction channel becomes blocked, the flow velocity on the surface of the guide vane 4 is measured. Sensor 21 receives a signal and transmits it to the controller. The controller's calculation module performs calculations, and then the operation module runs the system. Finally, the control module controls the booster pump 23, which pressurizes the fluid in the heat exchange pipe 1 to clear internal blockages. When the internal pressure of the heat exchange pipe 1 is too high, the pressure test sensor 31 detects a signal and transmits it to the controller. The controller's calculation module performs calculations, and then the operation module runs the system. Finally, the control module controls the booster pump 23, which reduces the pressure in the heat exchange pipe 1 after it is turned off.

[0031] refer to Figure 6 The two intersecting guide vanes 4 are snapped together.

[0032] The above scheme is adopted: the inclination angle between the guide vane 4 and the wall of the heat exchange pipe 1 is 45 degrees, and the guide vane 4 extends at a certain angle to the direction of water flow. In this way, the water flow entering the heat exchange pipe 1 from the opening will form a spiral motion under the combined action of the moment of momentum around the axis of the heat exchange pipe 1 and the water level difference along the axis of the heat exchange pipe 1, which will enhance the heat exchange of the heat exchange liquid to the heat source in the heat transfer pipe 2.

[0033] refer to Figure 5 The guide plate 4 has multiple sets of guide grooves 401 on the side near the heat transfer tube 2.

[0034] The above scheme, with the two intersecting guide vanes snapped together, ensures that the flow channel of the heat exchange liquid is spiral-shaped, preventing flow obstruction and dead zones, and improving flow efficiency.

[0035] refer to Figure 5 The guide plate 4 is made of aluminum alloy, and the outer periphery of the guide plate 4 is coated with a waterproof material, which is acrylic polyurethane paint.

[0036] By adopting the above scheme, the flow groove 401 on the surface of the flow guide plate 4 can increase the velocity of the heat exchange liquid when it flows through the surface of the flow guide plate 4, thereby enhancing the heat exchange speed.

[0037] refer to Figure 4 The heat-conducting block 5 is made of aluminum alloy and has a triangular cross-section.

[0038] The above solution is adopted: the guide vane 4 is made of aluminum alloy, and the outer periphery of the guide vane 4 is coated with a waterproof material, which is acrylic polyurethane paint. The aluminum alloy material has high strength and can prevent the guide vane 4 from breaking due to excessive water pressure. At the same time, the acrylic polyurethane paint on the outer periphery of the guide vane 4 can improve the waterproof performance of the guide vane 4, prevent the heat exchange liquid from corroding the aluminum alloy, and extend the service life of the guide vane 4.

[0039] refer to Figure 2 A sealing sleeve 101 is fixed on the outside of the contact area between the heat exchange pipe 1 and the water inlet pipe 22, and the heat transfer pipe 2 passes through the sealing sleeve 101.

[0040] The above scheme is adopted: the heat-conducting block 5 is made of aluminum alloy and has a triangular cross-section. The heat-conducting block 5 can improve the heat exchange efficiency of the heat transfer tube 2. At the same time, the triangular cross-section of the heat-conducting block 5 can increase the contact area between the heat transfer tube 2 and the heat exchange liquid, thereby improving the heat exchange efficiency.

[0041] refer to Figure 2 A waterproof gasket 102 is fixedly provided at the contact part between the sealing sleeve 101 and the heat transfer tube 2.

[0042] The above solution is adopted: a waterproof gasket 102 is fixed at the contact part between the sealing sleeve 101 and the heat transfer tube 2, which can prevent water leakage at the contact part between the sealing sleeve 101 and the heat transfer tube 2, and prevent water leakage caused by the pressure applied to the sealing sleeve 101 when the booster pump 23 is working, thus affecting the heat exchange efficiency.

[0043] refer to Figure 1 The PLC controller 3 is electrically connected to the booster pump 23.

[0044] The above solution involves electrically connecting the PLC controller 3 to the booster pump 23, allowing the PLC controller 3 to control the switching of the booster pump 23 and improve its efficiency.

[0045] Working principle of the invention: In operation, the heat source and cold source flow through heat transfer tube 2, while the heat exchange liquid flows through heat exchange pipe 1. The guide vane 4 changes the flow path of the heat exchange liquid through heat exchange pipe 1 from a direct current to a spiral flow, increasing the flow velocity of the heat exchange liquid and facilitating faster heat exchange between the heat source and cold source within heat transfer tube 2. The heat-conducting block 5 increases the contact area between heat transfer tube 2 and the heat exchange liquid, further facilitating faster heat exchange between the heat source and cold source inside heat transfer tube 2, ensuring full energy absorption and achieving high efficiency, energy saving, and environmental protection. When the heat conduction channel becomes blocked, the flow velocity on the surface of the guide vane 4 is measured. Sensor 21 receives a signal and transmits it to the controller. The controller's calculation module performs calculations, and then the operation module runs the system. Finally, the control module controls the booster pump 23, which pressurizes the fluid in the heat exchange pipe 1 to clear internal blockages. When the internal pressure of the heat exchange pipe 1 is too high, the pressure test sensor 31 detects a signal and transmits it to the controller. The controller's calculation module performs calculations, and then the operation module runs the system. Finally, the control module controls the booster pump 23, which reduces the pressure in the heat exchange pipe 1 after it is turned off.

[0046] In summary, this device for extracting hot and cold energy using spiral water flow solves the problem that existing methods of extracting hot and cold energy through pipes, which use direct current to achieve insufficient energy absorption, poor results, and wasted energy. This is achieved by using heat exchange pipe 1, heat transfer pipe 2, flow guiding components, and heat conducting components in combination.
