Description

Technical Field

[0001] This invention relates to the field of internal circulating cooling technology for cooling equipment, and particularly to a ready-to-use internal circulating cooling circuit device. A unidirectional flowing cooling medium is introduced into the annular space of the core cylindrical surface of the cooling equipment, creating a forced convection phenomenon on the inner cylindrical surface of the core. Through convective heat transfer and internal heat conduction of the solid components of the cooling equipment, overall cooling and temperature reduction of the potentially high-temperature equipment is achieved. Because the circulating cooling circuit device has excellent sealing performance, it enables environmentally friendly treatment and recycling of the cooling medium, saving cooling medium resources and the power energy required to transport the cooling medium, thus protecting the environment. Background Technology

[0002] Cooling equipment operates in high-temperature, dusty environments. Through convection, internal heat conduction, and radiation, the temperature of the equipment tends to rise, severely impacting its strength, rigidity, and other comprehensive mechanical properties. When external cooling methods like spray cooling are unsuitable for reducing the temperature of potentially overheating equipment, a well-designed internal cooling circuit and efficient cooling media design are crucial. Maximizing the cooling medium's effectiveness in controlling the overall temperature of the cooled equipment and reducing the temperature gradient is the only effective way to ensure its overall mechanical performance. This approach also facilitates the environmentally friendly treatment and recycling of the cooling medium and reduces the energy consumption associated with transporting large quantities of cooling medium. Summary of the Invention

[0003] The purpose of this invention is to provide a ready-to-use internal circulating cooling circuit device for equipment operating in high-temperature, dusty environments where external surface spray cooling is unsuitable and frequent equipment replacement is required. The circulating cooling circuit is naturally formed upon installation after equipment replacement, thanks to the function of the sealing components, and naturally disengages upon disassembly, facilitating easy replacement of the sealing components. This ready-to-use internal circulating cooling circuit device utilizes the cylindrical annular space in the core of the equipment to implement forced flow cooling of the cooling medium, effectively preventing excessive temperature rise and resulting in excellent overall mechanical properties. This invention belongs to the field of internal circulating cooling technology for cooling media.

[0004] The present invention includes: a functional shaft 1, a functional connector 2, a cooling device 3, an upper finned tube 4, a screw 5, a flange 6, an O-ring 1 7, an O-ring 2 8, an O-ring 3 9, a lower finned tube 10, fins of the upper finned tube 11, fins of the lower finned tube 12, a combined seal 13, and a combined seal 2 14.

[0005] A blind hole is opened at the center of the functional shaft 1, with the opening facing downwards. Two layers of connecting holes, an upper hole and a lower hole, are opened at the top to connect the blind hole and lead to the outside. The upper fin tube 4 is installed in the blind hole and fixed with screws 5 and flanges 6 under the positioning of the fins 11 of the upper fin tube. At the same time, the inner cylindrical surface of the blind hole of the functional shaft 1 and the outer cylindrical surface of the upper fin tube 4 form a cylindrical annular space. This cylindrical annular space connects the lower hole of the two layers of connecting holes, and the center hole of the upper fin tube 4 connects the upper hole of the two layers of connecting holes. Under the action of the combined seal 13 installed on its upper part, the two layers of connecting holes opened at the top of the functional shaft 1 are separated and not connected. The upper hole connects to the center hole of the upper fin tube 4. The two layers of annular grooves of functional connector 2 are connected to the upper and lower holes of the two layers of connecting holes of functional shaft 1 by the combined seal 14 installed in the internal cylindrical sealing groove. Cooling medium is introduced through the upper hole of functional shaft 1 by functional connector 2; return medium is discharged through the lower hole of functional shaft 1 by functional connector 2. Cooling medium enters through the central hole of upper fin tube 4; the annular space formed by the inner cylindrical surface of blind hole of functional shaft 1 and outer cylindrical surface of upper fin tube 4 allows cooling medium to flow back. The center of cooling device 3 has a blind hole with the opening facing upward. Lower fin tube 10 is circumferentially positioned by the fins 12 of lower fin tube and laterally positioned by gravity and installed in the blind hole of cooling device 3. When cooling device 3 is in operation, it has a certain amount of upward vertical movement; cooling medium enters through the central hole of lower fin tube 10; the annular space formed by the inner cylindrical surface of blind hole of cooling device 3 and outer cylindrical surface of lower fin tube 10 allows cooling medium to flow back, realizing forced convection cooling of the inner cylindrical surface of the core of cooling device 3. Functional connector 2 is connected to cooling device 3 in a certain manner, with a 1mm gap between them required for structural connection and disassembly. The center hole of upper finned tube 4 is connected to the center hole of lower finned tube 10, and the cylindrical annular space of functional shaft 1 is connected to the cylindrical annular space of cooling device 3. Functional connector 2 is circumferentially fixed, completing the introduction and return of cooling medium. Under the combined sealing action of O-ring 1 7, O-ring 2 8, and O-ring 3 9, a unidirectional circulating flow sealed cooling circuit is achieved inside cooling device 3.

[0006] The advantages of this invention are that the core cooling circuit of the cooling device 3 is designed as a unidirectional circulating flow sealed forced cooling circuit, which minimizes the risk of leakage during the flow of the cooling medium. The installation and disassembly of the cooling device 3 are simple and easy. The forced convection cooling circuit within the core of the cooling device 3 is easy to construct and can be automatically disconnected or restored synchronously. It also solves the risk of fin 11 detachment from the upper fin tube 4 caused by the end-face extrusion sealing connection between the upper fin tube 4 and the lower fin tube 10. Adjusting the pressure and flow rate of the cooling medium for forced convection cooling of the core of the cooling device 3 keeps the temperature rise of the cooling device 3 under operating conditions within a reasonable range, ensuring that the cooling device 3 has good overall mechanical performance. During the unidirectional circulating flow of the cooling medium in the cooling circuit, the entire flow is sealed, creating conditions for the environmentally friendly treatment and recycling of the cooling medium, saving energy for transporting the cooling medium, and protecting the environment.

[0007] In high-temperature environments, the temperature rise of the entire cooling device 3 is significant due to contact heat transfer, material conduction, and thermal radiation, severely impacting its overall mechanical properties. The most effective method to cool the cooling device 3 is to use a unidirectional cooling loop formed by the reverse flow of cooling medium through the central hole of the lower finned tube 10 to force convection cooling of the cylindrical surface inside the blind hole of the cooling device 3. This is the most efficient way to achieve the required temperature and good mechanical properties. Simultaneously, the presence of a large amount of dust on the working surface necessitates the sealing and protection of the forced convection cooling loop inside the cooling device 3. Furthermore, after disassembly, maintenance, or reassembly of the cooling device 3, the forced convection cooling loop can be easily and automatically restored synchronously.

[0008] The internal connection seal between the cooling medium inlet of the upper finned tube 4 and the lower finned tube 10 center hole in the cooling circuit is as follows: the seal after the upper finned tube 4 and the lower finned tube 10 are connected is a cylindrical piston type O-ring compression seal, which is achieved by the sealing function of O-ring 9. The lower finned tube 10 has a certain upward displacement, which is achieved by the clearance fit between the lower outer cylindrical surface of the upper finned tube 4 and the upper inner cylindrical surface of the lower finned tube 10. The two parts are easy to connect and disassemble, which solves the risk of the upper finned tube fin 11 falling off caused by the end face compression seal. The sealing surface of the O-ring 9 between the lower outer cylindrical surface of the upper finned tube 4 and the upper inner cylindrical surface of the lower finned tube 10 has a good sealing effect due to the small pressure difference. There will be no crossflow phenomenon during the unidirectional flow of the cooling medium. Due to structural connection and disassembly requirements, a 1mm gap is left between the lower end face of functional shaft 1 and the upper end face of cooling equipment 3. The external seal adopts an end seal plus a compression seal, which is called an end face axial O-ring compression seal. O-ring 8 forms the first external seal, and O-ring 7 forms the second external seal, which also serves as a dustproof function. The establishment of the two end face groove seals has a good sealing effect, ensuring that the cooling medium will not leak or be contaminated during the reflux cooling process, thus creating conditions for the environmentally friendly treatment and recycling of the cooling medium.

[0010] The present invention includes: a functional shaft 1, a functional connector 2, a cooling device 3, an upper finned tube 4, a screw 5, a flange 6, an O-ring 1 7, an O-ring 2 8, an O-ring 3 9, a lower finned tube 10, fins of the upper finned tube 11, fins of the lower finned tube 12, a combined seal 13, and a combined seal 2 14.

[0011] The specific implementation of the present invention will be described in detail below with reference to the accompanying drawings.

[0012] See Figure 1 , Figure 2 , Figure 3 Due to structural connection and disassembly requirements, a 1mm gap is maintained between the lower end face of functional shaft 1 and the upper end face of cooling device 3. When disassembling, repairing, or replacing cooling device 3, move it a certain distance away along its centerline perpendicular to the lower end face of functional shaft 1. Use appropriate tools and methods to disengage the upper finned tube 4 from the lower finned tube 10, and remove cooling device 3 along with the lower finned tube 10 for repair or replacement. Inspect or replace the O-rings 1-7, 2-8, and 3-9 that need replacement. Reinstalling cooling device 3: Insert the upper part of the lower finned tube 10 into the lower part of the upper finned tube 4, restoring the mechanical and sealing connection between functional shaft 1 and cooling device 3. Simultaneously, easily and automatically restore the forced convection cooling circuit inside cooling device 3.

[0013] See Figure 1 , Figure 2 , Figure 3When cooling of the cooling device 3 is required, the cooling medium enters from the upper layer of the functional connector 2. Under pressure, it flows sequentially into the central hole inside the upper finned tube 4 and the lower finned tube 10. During this process, it is sealed by the O-ring 9. At the bottom of the cooling device 3, it flows back into the cylindrical annular space formed by the cooling device 3 and the lower finned tube 10. The cooling medium provides forced convection cooling to the cylindrical core of the cooling device 3, effectively reducing the excessive temperature rise of the cooling device 3 under high-temperature conditions. By adjusting the flow rate and pressure of the cooling medium, the required temperature of the cooling device 3 can be obtained, giving the cooling device 3 good mechanical properties to meet the working requirements. The cooling medium continues to flow into the annular space formed by the functional shaft 1 and the upper finned tube 4. During this process, it is sealed by the end face of the O-ring 8, sealed externally and dustproof by the O-ring 7, and sealed by the cylindrical surface of the O-ring 9. It is then discharged through the lower layer of the functional connector 2. During the unidirectional circulation of the cooling medium, the entire process is sealed without leakage or pollution, creating conditions for the environmentally friendly treatment and recycling of the cooling medium.
