Description

Technical Field

[0001] The present invention relates to a drag reduction, energy saving and temperature control device comprising an adsorption unit, a temperature control unit, a turbulence generating unit and a surface opening and closing unit, and belongs to the field of carrier energy saving and environmental protection and carrier structure technology. Technical Background

[0002] The impact of fluid resistance on transportation vehicles such as automobiles, high-speed trains, and airplanes has always been a key issue in energy conservation. When the vehicle reaches a speed of 60 km / h, the energy consumed to overcome fluid resistance accounts for approximately 25% of the total energy consumption, and this energy ratio increases positively with increasing speed. Furthermore, regulating the internal temperature of the vehicle for human comfort is crucial. Therefore, this device proposes to reduce the vehicle's fluid resistance by generating turbulence based on spherical dimples on the surface. This can directly reduce energy loss during driving and control the vehicle's temperature, in line with development trends in this technology field.

[0003] The current methods of reducing fluid resistance are: (1) For high-speed carriers, drag reduction and energy saving. For example, cars usually adopt streamlined bodies, but in extreme weather conditions, the doors are difficult to open. (2) For ultra-high-speed carriers, drag reduction and energy saving. For example, high-speed trains adopt a streamlined design and also adopt active air extraction to reduce drag. Patent CN202410179116.X actively absorbs air to reduce drag by designing a duct fan and an air duct fan at the front of the train. Its disadvantage is that it reduces the space of the train cab. (3) For extremely high-speed carriers, drag reduction and energy saving. For example, aircraft use laminar flow control to delay boundary layer separation to reduce drag. Patent CN202410239218.6 uses an air intake wall panel to draw air from the surface part of the nacelle into the interior, so that the air on the outer surface part of the nacelle is greatly reduced, that is, there is very little air interacting with the boundary layer, thereby achieving the effect of maintaining a large area of laminar flow. Therefore, the current method of reducing carrier drag mainly controls the drag coefficient by adjusting the overall shape. Once the carrier shape is formed, it cannot be modified, and its versatility is very limited.

[0004] To overcome these issues, the present invention discloses a turbulent drag reduction, energy saving, and temperature control device. Its innovation lies in its ability to be arranged in an array on a pre-formed carrier, resulting in excellent applicability and the ability to actively control the carrier's temperature, promising promising applications. By comprehensively considering and improving upon the shortcomings of the three previously mentioned drag reduction methods, the invention innovatively employs an array of concave spherical surfaces and vortex tubes to cool hot air. This not only actively reduces driving resistance but also reduces the impact of external temperatures on the internal temperature through a thermal insulation layer, enhancing the device's practicality. Summary of the Invention

[0005] The present invention is used to solve the problems of large fluid resistance and lack of thermal insulation when the carrier is traveling, and provides a new turbulent drag reduction, energy saving and temperature control device. The present invention designs the drag reduction and temperature control functions on an independent device, which can be installed in an array on various types of carriers and has good applicability.

[0006] The present invention aims to solve the problems existing in the existing devices for reducing fluid resistance and makes a fundamental innovation. The basic idea is: ① The device is modularized and arrayed on the surface of the carrier. The concave spherical surface of the turbulence generating unit generates turbulence when the carrier is running at high speed, so that part of the air briefly adheres to the concave spherical surface and rotates around it. During the running, the fluid-solid friction between the air and the surface of the carrier is converted into the internal friction between the air and the air rotating inside the concave spherical surface of the carrier, thereby reducing the resistance of the carrier; ② The concave spherical surface is opened and closed by a transmission device such as a micro motor and a chain bead, which can make the concave spherical surface open and close. The spherical surface has the function of rain and dust protection when not in operation; ③ The vortex tube is used to draw compressed air from the air inlet into the annular space of the vortex tube at high speed along the tangential direction, forming a rotating airflow. The airflow is naturally divided into two parts: an inner low-pressure layer and an outer high-pressure layer. When the outer airflow is discharged through the valve, it adiabatically expands and cools down to become a cold airflow. When the inner airflow is discharged, it absorbs heat and becomes a hot airflow, thereby separating the compressed air into cold and hot airflows. The reversing valve is used to control the flow direction of the cold and warm air covering the carrier device group to realize the control of the temperature inside the temperature control layer, thereby achieving the effect of heat insulation in summer and warmth in winter.

[0007] To achieve the above-mentioned purpose and principle, the technical solution of the present invention is as follows:

[0008] A turbulent drag reduction, energy saving and temperature control device consists of four parts: an adsorption unit I, a temperature control unit II, a turbulent flow generating unit III, and a surface opening and closing unit IV;

[0009] The adsorption unit I is located at the bottom layer of the device, the temperature control unit II is located above the adsorption unit I, the turbulence generating unit III is installed above the temperature control unit II, and the surface opening and closing unit IV includes a transmission part and an execution part, the transmission part is located in the cavity formed by the turbulence generating unit III, and the execution part is located above the turbulence generating unit III;

[0010] The adsorption unit I comprises a circular suction cup 1 and a bonding auxiliary block 2;

[0011] The circular suction cup 1 and the bonding auxiliary block 2 are both installed below the temperature control unit II;

[0012] The bottom of the circular suction cup 1 is in direct contact with the carrier and is adsorbed on the carrier surface under negative pressure. Based on the structure of the circular suction cup 1, a portion of space is reserved between the temperature control unit II and the carrier surface, which can be filled with adhesive for composite connection, making the installation more reliable.

[0013] The bonding auxiliary block 2 is a T-shaped protruding structure, which is used to increase the bonding force points and improve the bonding effect when the adhesive solidifies between the temperature control unit II and the bonding auxiliary block 2;

[0014] The temperature control unit II includes a temperature control layer 3, a male connector 4, a female connector 5, a sealing ring 6, a vortex tube 7, and a reversing valve 8;

[0015] The temperature control layer 3 is a relatively closed chamber below the turbulence generating unit III. Male joints 4 and female joints 5 can be arranged on the side of the temperature control layer 3 as needed. Holes are designed at the top of the male joint 4 and the bottom of the female joint 5 to facilitate the flow of the gas. When arranged in an array, the male joint 4 of one device is embedded in the female joint 5 of the adjacent device, and a sealing ring 6 is added in the middle for sealing. The temperature control layers 3 of each device are connected to each other so that a relatively closed space is formed on the surface of the carrier, thereby interrupting the path of direct heat conduction from the outside and achieving temperature control protection for the carrier.

[0016] The temperature control principle of the temperature control unit II is to inject compressed gas into port A of the vortex tube 7. Under the action of the vortex tube 7, the energy of the compressed gas can be transferred, thereby generating hot air at port B and cold air at port C. Ports B and C are then connected to the inlet of the reversing valve 8 respectively. In cold weather, the hot air generated at port B is injected into the temperature control layer 3 to achieve a heat preservation function. In hot weather, the cold air generated at port C is injected into the temperature control layer 3 to achieve a heat insulation function, thereby achieving the purpose of regulating the temperature inside the carrier.

[0017] The turbulence generating unit III comprises a square outer shell 9 and a concave spherical surface 10;

[0018] The square housing 9 and the concave spherical surface 10 are connected by welding;

[0019] The square housing 9 is a relatively regular rectangular parallelepiped structure. This design facilitates subsequent array layout and adsorption on the carrier surface. The internal cavity is used for power transmission and installation of the transmission mechanism to ensure the normal operation of the surface opening and closing unit IV.

[0020] The concave spherical surface 10 is the surface where turbulence occurs. When the carrier runs at high speed, the fluid contacts the carrier and generates friction. The concave spherical surface 10 causes part of the fluid to be retained in the spherical chamber, forming an air film effect. This converts the wall friction between the fluid and the boundary layer of the high-speed moving carrier into viscous friction between the fluid and the fluid retained in the hemispherical chamber, thereby achieving the effect of reducing carrier drag and energy conservation.

[0021] The surface opening and closing unit IV includes a micro motor 11, a small chain bead gear 12, a cylindrical bead chain 13, a large chain bead gear 14, a transmission shaft 15, a transmission rope 16, a curtain 17, and a reel 18;

[0022] The micro motor 11 is mounted on the square housing 9 by bolt connection, the small chain bead gear 12 is mounted on the output shaft of the micro motor 11 by interference fit, the transmission shaft 15 is mounted on the bearing support of the square housing 9 by bearings, the large chain bead gear 14 and the transmission shaft 15 are coaxially rotated by interference fit, and the power of the micro motor 11 is transmitted between the small chain bead gear 12 and the large chain bead gear 14 through the cylindrical bead chain 13, thereby realizing the release and retraction of the curtain 17, thereby achieving the opening and closing of the surface of the device;

[0023] The micro motor 11 is a power source. The output shaft of the micro motor 11 is connected to the small chain bead gear 12 by an interference fit, and the rotation of the small chain bead gear 12 is realized. The small chain bead gear 12 and the cylindrical bead chain 13 are meshed with each other for transmission, so that the rotation of the cylindrical bead chain 13 can be realized. At the same time, the other end of the cylindrical bead chain 13 is meshed with the large chain bead gear 14, and the power of the small chain bead gear 12 is transmitted to the large chain bead gear 14. The rotation of the large chain bead gear 14 will drive the rotation of the transmission shaft 15. In addition, one end of the transmission rope 16 is fixed to the transmission shaft 15, and the other end is connected to the curtain 17. The transmission rope 16 adopts two groups of symmetrical arrangements. The rotation of the transmission shaft 15 causes the transmission rope 16 to roll up and shorten, and the curtain 17 is pulled out from the reel 18 to complete the closing, so as to prevent various impurities such as rainwater and dust from entering the concave spherical surface 10;

[0024] The output shaft of the micro motor 11 is reversed, driving the small chain bead gear 12 with an interference fit therewith to reverse, and then connected to the large chain bead gear 14 through the cylindrical bead chain 13 and driving the large chain bead gear 14 to reverse, thereby causing the transmission shaft 15 to also reverse and release the transmission rope 16. Under the action of the rebound force of the reel 18, the curtain 17 is wound around the reel 18, and the curtain 17 is retracted, so that the concave spherical surface 10 is in the working state;

[0025] The reel 18 includes an inner shaft 181, an outer shaft 182, a torsion spring 183, and a bearing 184;

[0026] The inner shaft 181 and the outer shaft 182 are arranged to rotate coaxially with each other through a bearing at each end, and a torsion spring is located between the inner shaft 181 and the outer shaft 182;

[0027] The inner shaft 181 is fixed to the square housing 9. The inner shaft 181 and the outer shaft 182 can rotate relative to each other coaxially via a bearing 184. A torsion spring 183 is arranged between the inner shaft 181 and the outer shaft 182. One end of the torsion spring 183 is fixed to the inner shaft 181, and the other end is fixed to the outer shaft 182. Under the action of the torsion spring 183, the inner shaft 181 and the outer shaft 182 have an initial position. The torsion force generated by the torsion spring causes the curtain 17 to be released and retracted, thereby realizing the opening and closing of the surface opening and closing unit IV.

[0028] The device can be used modularly, wherein the micro motors 11 are connected in parallel to the controller of the carrier to achieve unified opening and closing of all devices;

[0029] Step 1: The carrier starts, the opening and closing unit starts working, the motor is controlled to rotate forward, and the curtain is retracted through the transmission of various components, so that the concave spherical surface is located at the top layer of the device to reduce fluid resistance;

[0030] Step 2: The carrier stops, the motor is controlled to reverse, and the curtain is pulled out through the transmission of various components, so that the curtain is located at the top of the device, achieving the effect of dust and water proofing the device;

[0031] Step 3: After the carrier stops, the internal temperature of the carrier is judged. If the temperature is lower than 10℃ or higher than 30℃, the temperature control unit starts to work and injects compressed gas into the vortex tube A port. When the temperature is higher than 30℃, the reversing valve injects the cold air generated by the vortex tube C port into the temperature control layer. When the temperature is lower than 10℃, the reversing valve injects the hot air generated by the vortex tube B port into the temperature control layer to achieve control of the internal temperature of the carrier.

[0032] The beneficial effects of the present invention are:

[0033] 1. The present invention designs a turbulence generating unit, which uses its hemispherical chamber to convert the friction between the fluid and the carrier into friction between the fluid and the retained fluid, thereby achieving the effect of reducing drag and saving energy;

[0034] 2. To ensure the turbulence generating unit is rainproof and dustproof, an opening and closing unit with a curtain as the actuator is designed, which can prevent damage to the device from the external environment to a certain extent;

[0035] 3. This device is designed with concave and convex joints to achieve a multi-module array layout, and uses auxiliary bonding blocks. It is installed on the carrier surface using a combination of negative pressure adsorption and bonding. This method has a wide range of applications and is easy to install.

Specific implementation methods

[0046] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0047] Example 1: The device of the present invention is used in a family car in hot summer weather.

[0048] like Figure 1-8 A turbulent drag reduction, energy saving and temperature control device is composed of four parts: adsorption unit I, temperature control unit II, turbulence generation unit III and surface opening and closing unit IV.

[0049] The adsorption unit I is located at the bottom layer of the device, the temperature control unit II is located above the adsorption unit I, the turbulence generating unit III is installed above the temperature control unit II, and the surface opening and closing unit IV includes a transmission part and an execution part, the transmission part is located in the cavity formed by the turbulence generating unit III, and the execution part is located above the turbulence generating unit III;

[0050] The adsorption unit I comprises a circular suction cup 1 and a bonding auxiliary block 2;

[0051] The circular suction cup 1 and the bonding auxiliary block 2 are both installed below the temperature control unit II;

[0052] The bottom of the circular suction cup 1 is in direct contact with the carrier and is adsorbed on the carrier surface under negative pressure. Based on the structure of the circular suction cup 1, a portion of space is reserved between the temperature control unit II and the carrier surface, which can be filled with adhesive for composite connection, making the installation more reliable.

[0053] The bonding auxiliary block 2 is a T-shaped protruding structure, which is used to increase the bonding force points and improve the bonding effect when the adhesive solidifies between the temperature control unit II and the bonding auxiliary block 2;

[0054] The temperature control unit II includes a temperature control layer 3, a male connector 4, a female connector 5, a sealing ring 6, a vortex tube 7, and a reversing valve 8;

[0055] The temperature control layer 3 is a relatively closed chamber below the turbulence generating unit III. Male joints 4 and female joints 5 can be arranged on the side of the temperature control layer 3 as needed. Holes are designed at the top of the male joint 4 and the bottom of the female joint 5 to facilitate the flow of the gas. When arranged in an array, the male joint 4 of one device is embedded in the female joint 5 of the adjacent device, and a sealing ring 6 is added in the middle for sealing. The temperature control layers 3 of each device are connected to each other so that a relatively closed space is formed on the surface of the carrier, thereby interrupting the path of direct heat conduction from the outside and achieving temperature control protection for the carrier.

[0056] The temperature control principle of the temperature control unit II is to inject compressed gas into port A of the vortex tube 7. Under the action of the vortex tube 7, the energy of the compressed gas can be transferred, thereby generating cold air at port C. Port C is then connected to the inlet of the reversing valve 8. In hot weather, the cold air generated at port C is injected into the temperature control layer 3 to achieve a heat insulation function, thereby preventing the heat outside the vehicle from entering the vehicle and achieving a cooling effect.

[0057] The turbulence generating unit III comprises a square outer shell 9 and a concave spherical surface 10;

[0058] The square housing 9 and the concave spherical surface 10 are connected by welding;

[0059] The square housing 9 is a relatively regular rectangular parallelepiped structure. This design facilitates subsequent array layout and adsorption on the carrier surface. The internal cavity is used for power transmission and installation of the transmission mechanism to ensure the normal operation of the surface opening and closing unit IV.

[0060] The concave spherical surface 10 is a turbulent surface. When the carrier runs at high speed, the fluid contacts the carrier and generates friction. The concave spherical surface 10 causes part of the fluid to be retained in the spherical cavity, thereby converting the friction between the fluid and the carrier into friction between the fluid and the retained fluid, thereby achieving the effect of reducing the carrier's drag.

[0061] The surface opening and closing unit IV includes a micro motor 11, a small chain bead gear 12, a cylindrical bead chain 13, a large chain bead gear 14, a transmission shaft 15, a transmission rope 16, a curtain 17, and a reel 18;

[0062] The micro motor 11 is mounted on the square housing 9 by bolt connection, the small chain bead gear 12 is mounted on the output shaft of the micro motor 11 by interference fit, the transmission shaft 15 is mounted on the bearing support of the square housing 9 by bearings, the large chain bead gear 14 and the transmission shaft 15 are coaxially rotated by interference fit, and the power of the micro motor 11 is transmitted between the small chain bead gear 12 and the large chain bead gear 14 through the cylindrical bead chain 13, thereby realizing the release and retraction of the curtain 17, thereby achieving the opening and closing of the surface of the device;

[0063] The micro motor 11 is a power source. The output shaft of the micro motor 11 is connected to the small chain bead gear 12 by an interference fit, and the rotation of the small chain bead gear 12 is realized. The small chain bead gear 12 and the cylindrical bead chain 13 are meshed with each other for transmission, so that the rotation of the cylindrical bead chain 13 can be realized. At the same time, the other end of the cylindrical bead chain 13 is meshed with the large chain bead gear 14, and the power of the small chain bead gear 12 is transmitted to the large chain bead gear 14. The rotation of the large chain bead gear 14 will drive the rotation of the transmission shaft 15. In addition, one end of the transmission rope 16 is fixed to the transmission shaft 15, and the other end is connected to the curtain 17. The transmission rope 16 adopts two groups of symmetrical arrangements. The rotation of the transmission shaft 15 causes the transmission rope 16 to roll up and shorten, and the curtain 17 is pulled out from the reel 18 to complete the closing, so as to prevent various impurities such as rainwater and dust from entering the concave spherical surface 10;

[0064] The output shaft of the micro motor 11 is reversed, driving the small chain bead gear 12 with an interference fit therewith to reverse, and then connected to the large chain bead gear 14 through the cylindrical bead chain 13 and driving the large chain bead gear 14 to reverse, thereby causing the transmission shaft 15 to also reverse and release the transmission rope 16. Under the action of the rebound force of the reel 18, the curtain 17 is wound around the reel 18, and the curtain 17 is retracted, so that the concave spherical surface 10 is in the working state;

[0065] The reel 18 includes an inner shaft 181, an outer shaft 182, a torsion spring 183, and a bearing 184;

[0066] The inner shaft 181 and the outer shaft 182 are arranged to rotate coaxially with each other through a bearing at each end, and a torsion spring is located between the inner shaft 181 and the outer shaft 182;

[0067] The inner shaft 181 is fixed to the square housing 9. The inner shaft 181 and the outer shaft 182 can rotate relative to each other coaxially via a bearing 184. A torsion spring 183 is arranged between the inner shaft 181 and the outer shaft 182. One end of the torsion spring 183 is fixed to the inner shaft 181, and the other end is fixed to the outer shaft 182. Under the action of the torsion spring 183, the inner shaft 181 and the outer shaft 182 have an initial position. The torsion force generated by the torsion spring causes the curtain 17 to be released and retracted, thereby realizing the opening and closing of the surface opening and closing unit IV.

[0068] The device can be used in a modular manner, wherein the micro motors 11 are uniformly connected to the controller of the carrier in a parallel manner to achieve unified opening and closing of all devices.

[0069] Example 2: The device of the present invention is used in a family car in cold winter weather.

[0070] The specific implementation methods of the adsorption unit I, turbulence generation unit III, and surface opening and closing unit IV are similar to those in Example 1, except for the specific implementation method of the temperature control unit II.

[0071] The temperature control unit II includes a temperature control layer 3, a male connector 4, a female connector 5, a sealing ring 6, a vortex tube 7, and a reversing valve 8;

[0072] The temperature control layer 3 is a relatively closed chamber below the turbulence generating unit III. Male joints 4 and female joints 5 can be arranged on the side of the temperature control layer 3 as needed. Holes are designed at the top of the male joint 4 and the bottom of the female joint 5 to facilitate the flow of the gas. When arranged in an array, the male joint 4 of one device is embedded in the female joint 5 of the adjacent device, and a sealing ring 6 is added in the middle for sealing. The temperature control layers 3 of each device are connected to each other so that a relatively closed space is formed on the surface of the carrier, thereby interrupting the path of direct heat conduction from the outside and achieving temperature control protection for the carrier.

[0073] The temperature control principle of the temperature control unit II is to inject compressed gas into port A of the vortex tube 7. Under the action of the vortex tube 7, the energy of the compressed gas can be transferred, thereby generating hot air at port B. Port B is then connected to the inlet of the reversing valve 8. In hot weather, the hot air generated at port B is injected into the temperature control layer 3 to achieve a heat preservation function and prevent the temperature inside the vehicle from being too low.

[0074] The first step: using a circular suction cup 1 to adsorb the present invention in an array layout onto the surface of the vehicle body, during the installation process, the convex joints 4 and concave joints 5 on each device are used to form the temperature control layer 3 of each device into a whole, and relative sealing is achieved with the use of a sealing ring 6, and finally, gluing is used through the gluing auxiliary block 2 to make the device more reliably adsorbed onto the surface of the vehicle body.

[0075] Step 2 (when the vehicle is running): Start the micro motor 11 to drive the small chain bead gear 12, and transmit the power to the large chain bead gear 14 through the cylindrical bead chain 13. The large chain bead gear 14 drives the transmission shaft 15, so that the transmission rope 16 loses its tension. Under the action of the torsion spring 183 of the reel 18, the curtain 17 is retracted. At this time, the concave spherical surface 10 is located on the outermost surface to achieve a drag reduction effect.

[0076] Step 3 (when the vehicle stops): Start the micro motor 11 to drive the small chain bead gear 12, and transmit the power to the large chain bead gear 14 through the cylindrical bead chain 13. The large chain bead gear 14 drives the transmission shaft 15, thereby shortening the transmission rope 16, overcoming the torsional force of the reel 18 and pulling out the curtain 17, and using the curtain 17 to protect the device from rain and dust.

[0077] Step 4: Determine the ambient temperature. If the ambient temperature is higher than 30°C, inject compressed gas into the vortex tube A port, and inject the cold air generated by the vortex tube C port into the temperature control layer through the reversing valve. If the ambient temperature is lower than 10°C, inject compressed gas into the vortex tube A port, and inject the hot air generated by the vortex tube B port into the temperature control layer through the reversing valve to achieve temperature control inside the vehicle.

[0078] The specific embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the scope of the present invention.
