Description

Technical Field

[0001] The present invention relates to the technical field of glass manufacturing, and in particular to a glass calendering device. Background Art

[0002] In the process of glass manufacturing, the calendering process is one of the important processes for producing flat glass, photovoltaic glass and other products.

[0003] The cooling method of traditional calendering rolls mostly adopts a straight-through cooling channel or external spray cooling. The contact area between the coolant and the roll body is limited, resulting in uneven cooling, large fluctuations in the roll surface temperature, and easily causing defects such as micro-cracks, warping or uneven thickness on the glass surface, affecting product quality. In addition, the existing cooling system has a complex structure, inconvenient maintenance, and low cooling efficiency, which is difficult to meet the requirements of high-quality glass production. For this reason, we propose a glass calendering device. Summary of the Invention

[0004] The present invention is a glass calendering device proposed to solve the shortcomings existing in the prior art. This glass calendering device solves the problem that the limited contact area between the coolant and the roll body leads to uneven cooling, large fluctuations in the roll surface temperature, and easily causes defects such as micro-cracks, warping or uneven thickness on the glass surface.

[0005] In order to achieve the above object, the present invention adopts the following technical scheme: A glass calendering device includes a support plate and a heat exchange pump group. On the upper side of the support plate, a first side plate and a second side plate are symmetrically arranged in parallel. Between the first side plate and the second side plate, two calendering rolls are provided. Inside the calendering roll, a cold flow channel is provided. The cold flow channel is arranged in a spiral variable cross-section flow channel structure. A metal-ceramic composite is sleeved outside the calendering roll. A cold flow injection hole is provided on one side of the calendering roll, and a plurality of liquid discharge holes are provided on the other side of the calendering roll. On one side of the first side plate, a driving component for rotating the calendering roll is provided. On one side of the second side plate, a cold flow conveying part is provided. On one side of the first side plate, a heat flow conveying and converting part is provided.

[0006] Through the above technical scheme, the present application effectively solves the product defect problem caused by uneven cooling of the calendering roll. The dynamic coverage characteristic of the spiral flow channel controls the surface temperature fluctuation of the roll body within ±. °C. The metal-ceramic composite layer significantly reduces the surface thermal stress concentration, and the closed-loop system realizes the recovery and utilization of waste heat. In practical applications, this device can reduce the warpage rate of ultra-thin glass to less than 0.02%, and at the same time extend the service life of the calendering roll to more than 12,000 hours.

[0007] Preferably, the driving assembly includes a mounting frame which is arranged on one side of the first side plate. A motor is arranged on one side of the mounting frame. A first gear is arranged at the output shaft end of the motor. A second gear is meshed and connected to one side of the first gear. One side of the second gear is sleeved on one side of the calender roll.

[0008] Through the above technical solution, the present application solves the problem of the cooling effect fluctuation caused by the unstable transmission of the calender roll, ensures the uniform flow of the cold fluid in the roll body, and reduces the surface micro-cracks or thickness unevenness defects caused by the temperature difference during the glass forming process, thereby improving the quality consistency of the glass products.

[0009] Preferably, the cold fluid conveying part includes a cold fluid placing component, a cold fluid sucking component and a cold fluid guiding component. The cold fluid placing component includes a coolant tank which is arranged between the first side plate and the second side plate. A tank cover is rotatably connected to the upper side of the coolant tank.

[0010] Preferably, the cold fluid guiding component includes a cold fluid suction pipe which is arranged in the coolant tank. A cold fluid conduit is inserted into one side of the cold fluid suction pipe. A cold fluid shunt pipe is inserted into one end of the cold fluid conduit. A first sealing bearing is arranged at the end of the cold fluid shunt pipe and is connected in the cold fluid injection hole. A shunt block is arranged in the middle of the inner side of the cold fluid shunt pipe.

[0011] Through the above technical solution, the present application solves the problems of the unstable flow path and uneven distribution of the coolant inside the calender roll, ensures that the coolant continuously and evenly enters the spiral deformation runoff channel during the dynamic rotation process, and effectively reduces the temperature fluctuation of the roll surface. The shunt block structure promotes the formation of a laminar flow state of the coolant at the inlet of the flow channel, avoiding local overheating or overcooling caused by turbulent flow. The combined design of the first sealing bearing and the cold fluid shunt pipe simplifies the pipeline layout while ensuring the sealing performance. The detachable structure of the cold fluid conduit further improves the maintenance convenience.

[0012] Preferably, the cold fluid sucking component includes a first connecting rod which is arranged on one side of the first gear. A third gear is arranged at one end of the first connecting rod. A fourth gear is meshed and connected to one side of the third gear. A fifth gear is meshed and connected to one side of the fourth gear. A second connecting rod is arranged on one side of the fifth gear. An impeller is arranged at one end of the second connecting rod and is placed inside the cold fluid suction pipe.

[0013] Through the above technical solution, the present application can realize the power coupling of the coolant circulation system and the calender roll drive system, reduce the energy consumption while ensuring that the coolant flow rate is synchronized with the working state of the calender roll, avoid the problem of uneven contact of the inner wall of the roll body caused by the flow rate fluctuation, and further reduce the temperature gradient difference during the glass forming process.

[0014] Preferably, the heat flow transportation and conversion part includes a plug hole, which is arranged on one side of the first side plate. The calender roll is inserted into the plug hole. A liquid collecting groove is arranged on one side of the plug hole. The drain hole is communicated with the liquid collecting groove. Two sealing bearings II are arranged in the liquid collecting groove. The sealing bearing II is connected to one end of the calender roll. An arc-shaped flow guide plate is arranged in the liquid collecting groove. The arc-shaped flow guide plate is located between the two sealing bearings II. A heat flow conduit is arranged on one side of the liquid collecting groove. The heat exchange pump group is arranged outside the heat flow conduit. A partition is arranged in the coolant tank. An overflow hole is arranged on the partition. A transfer groove is arranged on one side of the partition. One end of the heat flow conduit is connected to one side of the transfer groove.

[0015] Through the above technical solution, the present application realizes the efficient directional recovery of heat flow, improves the temperature stability of the coolant, and significantly reduces the incidence of micro-crack defects caused by temperature fluctuations during the glass forming process.

[0016] Preferably, a storage groove is arranged on one side of the second side plate. Part of the cold flow conduit is placed in the storage groove. A limiting block is arranged in the storage groove. One side of the limiting block abuts against one side of the cold flow conduit.

[0017] The present application effectively prevents the cold flow conduit from shifting or vibrating during the transportation of the coolant, avoids coolant leakage and pressure loss caused by the loosening of the conduit, ensures that the coolant is continuously transported to the inside of the calender roll at a stable flow rate and pressure, and maintains the continuous and stable operation of the cooling system. Preferably, protective shells are arranged on one side of the first side plate and the second side plate respectively. A shell cover is rotatably connected to one side of the protective shell.

[0018] Through the above technical solution, the present application effectively blocks the intrusion of dust particles in the production environment into the transmission components, reduces the occurrence probability of abnormal wear of gears and pipeline blockage. The flip-type shell cover design reduces the time-consuming of daily lubrication, pipeline inspection and other maintenance operations. The operator can complete routine maintenance without using special tools to disassemble the shell, and the equipment downtime is compressed.

[0019] In summary, in the present invention, by combining the spiral variable-diameter cold flow channel with the cermet composite, the contact area between the coolant and the roll body is enhanced, uniform and efficient cooling is realized, the surface defects of the glass are reduced, and it has the advantages of improving the cooling uniformity, reducing the temperature fluctuation of the roll surface, enhancing the cooling efficiency and prolonging the service life of the calender roll.

[0020] The present invention, an intelligent cooling circulation system, reduces energy consumption. The forced circulation design of the cold flow conveying part uses gears to drive the impeller (gears three, four, and five are linked), and the flow rate of the coolant can be automatically adjusted according to the calendering speed to avoid energy waste. The heat flow conveying and conversion part, through the cooperation of the sealing bearing two and the arc-shaped guide plate, efficiently recovers the high-temperature coolant and conducts heat energy reuse through the heat exchange pump group, reducing the overall energy consumption by more than 30%.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] 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.

[0024] As Figure 1 - Figure 9 shown, a glass calendering device includes a support plate 1 and a heat exchange pump group 32. On the upper side of the support plate 1, a first side plate 2 and a second side plate 3 are symmetrically arranged in parallel. Between the first side plate 2 and the second side plate 3, two calendering rollers 4 are arranged. Inside the calendering rollers 4, a cold flow channel 5 is arranged. The cold flow channel 5 has a spiral-shaped variable cross-section flow channel structure. A cermet composite is sleeved outside the calendering rollers 4. On one side of the calendering roller 4, a cold flow injection hole 6 is arranged, and on the other side, a number of liquid discharge holes 7 are arranged. A driving component is arranged on the first side plate 2, and a cold flow conveying part is arranged on the second side plate 3. A heat flow conveying and converting part is arranged on the first side plate 4.

[0025] Among them, the spiral-shaped variable cross-section flow channel structure refers to a channel structure in which the cross-sectional size of the flow channel changes regularly along the spiral axis direction. For example, a pipe diameter design with alternating gradual contraction and gradual expansion can be adopted. This structure can break the laminar boundary layer, enhance the turbulence intensity of the cooling liquid, and enable the fluid to fully contact the inner wall of the roller body.

[0026] The cermet composite includes a metal matrix and a ceramic coating. For example, tungsten carbide hard alloy can be selected as the surface material, and a composite structure is formed through a thermal spraying process to improve the surface heat conduction coefficient while maintaining the mechanical strength of the roller body.

[0027] The cold flow injection hole and the liquid discharge hole form a pressure difference driving system. For example, the liquid discharge hole can be set with a hole diameter of 0.5 - 3 mm and distributed in a honeycomb array to ensure that the cooling liquid is evenly discharged after flowing through the spiral channel.

[0028] The driving component and the cold flow conveying part are arranged separately. For example, the motor drive system and the cooling liquid circulation system are respectively arranged on the two side plates to avoid vibration interference with the stability of fluid transportation.

[0029] Specifically, when the cooling liquid enters the spiral-shaped variable cross-section flow channel through the cold flow injection hole 6, the Venturi effect generated by the variable diameter structure accelerates the fluid movement, and at the same time, the periodic change in pipe diameter causes the formation of eddies.

[0030] The high heat conduction characteristics of the cermet composite enable the heat on the surface of the roller body to be quickly transferred to the wall surface of the flow channel. The spiral path prolongs the contact time between the cooling liquid and the wall surface of the flow channel. After the cooling liquid that has completed heat exchange is discharged through the liquid discharge hole 7, the waste heat is recovered through the heat flow conveying and converting part to form a closed-loop energy cycle.

[0031] The symmetrical layout of the two calendering rollers 4 forms a stable calendering working area, and the independent setting of the driving component avoids mutual interference between the cooling system and the power system.

[0032] Compared with the prior art, in the traditional straight-through flow channel, the coolant flows unidirectionally in a laminar state, resulting in an obvious temperature gradient in the axial direction of the roller body. The spiral variable-flow channel of the present application causes strong turbulence of the coolant both radially and axially through forced fluid diversion and flow velocity change. For example, at the same flow rate, the turbulence intensity can be increased by more than 40%.

[0033] The thermal conductivity efficiency of the cermet composite structure is increased by about 30% compared with the traditional alloy roller body, and the surface hardness is increased by 2 - 3 times. The closed-loop cooling circulation system reduces the coolant loss by about 25% compared with the traditional open system.

[0034] The driving assembly includes a mounting bracket 8, which is arranged on one side of the first side plate 2. A motor 9 is arranged on one side of the mounting bracket 8. A first gear 10 is arranged at the output shaft end of the motor 9. A second gear 11 is meshed and connected to one side of the first gear 10. The second gear 11 is sleeved on one side of the calender roll 4. Among them, the mounting bracket 8 refers to a support structure for fixing the motor, which can be specifically realized by welding steel plates or casting integrally formed, providing rigid support for the motor 9 and avoiding gear meshing deviation caused by vibration during the transmission process.

[0035] Among them, the meshing of the first gear 10 and the second gear 11 refers to a mechanical connection method of transmitting power through tooth surface contact. For example, helical gears or spur gears are used to form a first-stage reduction drive, which improves the stability of torque output while reducing the speed, thereby reducing the speed fluctuation of the calender roll.

[0036] Among them, the second gear 11 being sleeved on one side of the calender roll 4 refers to realizing power transmission through keyway fitting or interference fit. For example, flange connection or spline connection is used to directly convert the rotational motion of the second gear 11 into the uniform rotation of the calender roll 4, avoiding energy loss or transmission delay caused by intermediate transmission links.

[0037] Specifically, the mounting bracket 8 is fixed on one side of the first side plate 2, the motor 9 is installed on the mounting bracket 8, the first gear 10 at the output shaft end meshes with the second gear 11 to form a first-stage reduction drive structure, and the second gear 11 is sleeved on the end of the calender roll through a rigid connection method, so that the power output by the motor is directly transmitted to the calender roll 4 to ensure its uniform speed.

[0038] Due to the high contact precision of gear meshing transmission and the stable support of the mounting bracket 8, the vibration and speed fluctuation during the transmission process are effectively suppressed. The uniform rotation of the calender roll 4 further ensures the stable flow of the cooling medium in the cold flow channel 5, thereby avoiding uneven temperature distribution on the roll surface caused by sudden speed change.

[0039] Compared with the existing technology, the traditional drive assembly usually adopts chain or belt transmission, which is easy to cause transmission slippage due to insufficient tension or wear, thereby causing the calender roller speed fluctuation. However, this solution eliminates the inherent defects of flexible transmission parts by combining gear meshing transmission with rigid mounting structure, and significantly improves the reliability and stability of power transmission.

[0040] The cold flow conveying part includes a cold flow placement component, a cold flow suction component and a cold flow guide component. The cold flow placement component includes a coolant tank, which is arranged between the side plate 1 2 and the side plate 2 3. The upper side of the coolant tank 13 is flipped and connected with a box cover 14.

[0041] Among them, the cold flow placement component refers to a modular structure for storing and supplying coolant, which can be specifically realized by a metal box fixedly installed between the side panels. Its position layout shortens the coolant supply path and reduces flow resistance.

[0042] The coolant tank 13 refers to a container with a sealed cover, which can be specifically realized by a welded stainless steel box, with partitions arranged inside to separate different functional areas, so as to facilitate the circulation of coolant and the precipitation of impurities.

[0043] The flip connection of the box cover 14 refers to the opening and closing operation achieved through a hinge structure, which can be specifically achieved by a rotating shaft in conjunction with a sealing strip, so that the inside of the box can be kept closed while adding coolant to prevent external contaminants from entering.

[0044] The cold flow guide component includes a cold flow suction pipe 15, which is arranged in the cooling liquid tank 13. A cold flow conduit 16 is inserted on one side of the cold flow suction pipe 15, and a cold flow shunt pipe 17 is inserted on one end of the cold flow conduit 16. A sealing bearing 18 is provided at the end of the cold flow shunt pipe 17, and the sealing bearing 18 is connected to the cold flow injection hole 6. A shunt block 24 is provided in the middle of the inner side of the cold flow shunt pipe 17.

[0045] The cold flow suction pipe 15 refers to a tubular structure for sucking coolant from the coolant tank, and can be made of metal or corrosion-resistant plastic material. Its inlet end can extend to the bottom of the coolant tank 13 to fully absorb the liquid.

[0046] The cold flow conduit 16 refers to a connecting pipeline for conveying coolant, and may specifically adopt a detachable threaded interface or a snap-fit structure to facilitate quick disassembly and assembly during maintenance.

[0047] The cold flow diverter pipe 17 refers to a transition structure for evenly distributing the cooling liquid to the internal flow channel of the calendering roller, and the cross section of the internal cavity can be designed to be a symmetrical gradient shape to meet the inlet requirements of the spiral variable diameter flow channel.

[0048] The sealed bearing 18 refers to a rotating connecting component that realizes the dynamic seal between the cold flow diversion pipe 17 and the calender roll 4. A mechanical seal or a magnetic fluid seal structure can be adopted to ensure that there is no leakage of the coolant when the calender roll rotates.

[0049] The flow splitting block 24 refers to a flow guiding structure arranged inside the cold flow diversion pipe. Specifically, a conical or airfoil profile can be adopted. By guiding the fluid to change the flow direction and balance the flow velocity, the coolant forms a stable laminar flow state before entering the calender roll.

[0050] Specifically, after the coolant is extracted from the coolant tank 13 through the cold flow liquid suction pipe 15, it is transported to the cold flow diversion pipe 17 through the cold flow conduit 16. The cold flow diversion pipe 17 is rotationally and sealedly connected to the cold flow injection hole 6 of the calender roll 4 through the sealed bearing 17, so that the coolant can still be stably injected during the continuous rotation of the calender roll 4. The flow splitting block 24 guides the fluid in the middle of the cold flow diversion pipe 17. By changing the cross-sectional area of the flow channel, the coolant completes the flow velocity balance before entering the spiral deformed radial flow channel inside the calender roll 4. The matching structure of the sealed bearing 18 and the calender roll 4 allows the cold flow diversion pipe to remain stationary while the calender roll 4 rotates independently, avoiding pipeline entanglement or seal failure caused by relative movement. The plug-in structure of the cold flow conduit 16 and the cold flow liquid suction pipe 15 facilitates quick separation during maintenance. At the same time, the flow splitting design of the cold flow diversion pipe 17 ensures that the coolant is evenly distributed in the spiral flow channel, avoiding temperature fluctuations caused by flow velocity differences in local areas.

[0051] Compared with the prior art, when the traditional technology adopts a straight-through cooling flow channel, the coolant only flows along a fixed path, which is difficult to adapt to the rotation working condition of the calender roll, and the lack of flow velocity control leads to uneven distribution. However, in this solution, through the cooperation of the cold flow diversion pipe 17 and the sealed bearing 18, stable injection of the coolant is achieved while maintaining the rotational seal. The introduction of the flow splitting block 24 further optimizes the initial flow state of the fluid, enabling the coolant to form a uniform coverage in the spiral deformed radial flow channel, overcoming the problem of low cooling efficiency caused by a single flow path in the traditional technology.

[0052] The cold flow suction assembly includes a connecting rod 12. The connecting rod 12 is arranged on one side of the gear 10. One end of the connecting rod 12 is provided with a gear 19. One side of the gear 19 is meshed with a gear 20. One side of the gear 20 is meshed with a gear 21. One side of the gear 21 is provided with a connecting rod 22. One end of the connecting rod 22 is provided with an impeller 23. The impeller 23 is placed inside the cold flow liquid suction pipe 15.

[0053] Among them, the connecting rod 12 refers to a rod-shaped component used to transmit the rotational power of the gear 10. Specifically, it can be realized by connecting the shaft end on one side of the gear with a steel coupling, and is used to transmit the output power of the motor 9 to the cold flow suction assembly.

[0054] Among them, the third gear 19, the fourth gear 20 and the fifth gear 21 refer to a set of meshing gears that form a three-stage transmission relationship. Specifically, helical gears or spur gears can be used in combination with the adjustment of the reduction ratio to achieve this. By means of multi-stage meshing, the rotational speed is reduced and the torque is increased, so as to adapt to the working requirements of the impeller 23.

[0055] Among them, the impeller 23 refers to a centrifugal fluid drive component that generates negative pressure through rotation. Specifically, it can be realized by adopting a structure in which stainless steel blades and a shaft body are integrally formed. When placed inside the cold flow liquid suction pipe 15, it can suck in the coolant and push it to flow.

[0056] Specifically, after the first connecting rod 12 obtains the rotational power output by the motor 9 through the first gear 10, it drives the third gear 19 to rotate. The meshing of the third gear 19 and the fourth gear 20 completes the first-stage reduction, and the fourth gear 20 then meshes with the fifth gear 21 to achieve the second-stage reduction. Finally, the adjusted rotational speed is transmitted to the impeller 23 through the second connecting rod 12. When the impeller 23 rotates in the cold flow liquid suction pipe 15, the negative pressure generated by its blades sucks the coolant from the liquid suction pipe inlet and transports it along the pipeline to the cold flow injection hole 6. Through the design of the reduction ratio of the three-stage gear transmission, the rotational speed of the impeller can be controlled within a range lower than the rotational speed of the calender roll, thereby avoiding sudden changes in the coolant flow rate caused by too high a rotational speed and ensuring the stability of the circulation process.

[0057] Compared with the prior art, the traditional coolant circulation system needs to additionally configure an independent motor to drive an external pump body, which not only occupies space but also has high energy consumption. In this solution, the remaining power of the calender roll driving motor is directly utilized through a gear set, without the need to add an external power source. At the same time, the multi-stage reduction structure enables a fixed proportional relationship to be formed between the rotational speed of the impeller and the rotational speed of the calender roll, and the coolant flow rate is automatically adjusted with the rotational speed of the calender roll, solving the problem of flow matching caused by external independent driving.

[0058] The heat flow transmission conversion part includes a plug hole 27. The plug hole 27 is arranged on one side of the first side plate 2. The calender roll 4 is inserted into the plug hole 27. A liquid receiving groove 28 is arranged on one side of the plug hole 27. The drain hole 7 is arranged in a communicating state with the liquid receiving groove 28. Two second sealing bearings 29 are arranged in the liquid receiving groove 28. The second sealing bearings 29 are connected to one end of the calender roll 4. An arc-shaped guide plate 30 is arranged in the liquid receiving groove 28. The arc-shaped guide plate 30 is located between the two second sealing bearings 29. A heat flow conduit 31 is arranged on one side of the liquid receiving groove 28. The heat exchange pump group 32 is arranged outside the heat flow conduit 31. A partition 33 is arranged in the coolant tank 13. An overflow hole 34 is arranged on the partition 33. A transfer groove 35 is arranged on one side of the partition 33. One end of the heat flow conduit 31 is connected to one side of the transfer groove 35.

[0059] Among them, the insertion hole 27 refers to the hole structure opened on the side of the first side plate 2, which is used to accommodate the end of the calender roll 4 and form a rotational sealing connection. Specifically, a combination structure of a bushing and a sealing ring can be adopted to prevent coolant leakage when the calender roll rotates.

[0060] Among them, the liquid collection groove 28 refers to the groove structure arranged on the side of the insertion hole 27, which is communicated with the drain hole. Specifically, it can be formed by casting or welding, and is used to collect the heat flow discharged from the calender roll 4.

[0061] Among them, the second sealing bearing 29 refers to the rolling bearing installed in the liquid collection groove 28. Specifically, a double-row angular contact ball bearing can be adopted and filled with high-temperature resistant sealing grease to prevent the heat flow from entering the bearing clearance while supporting the rotation of the calender roll.

[0062] Among them, the arc-shaped deflector 30 refers to the metal plate with a curved profile. Specifically, a stainless steel plate can be selected and stamped to guide the heat flow along a preset path to the inlet of the heat flow conduit 31. Among them, the partition plate 33 refers to the plate-like structure vertically arranged inside the coolant tank 13. Specifically, it can be cut from a polytetrafluoroethylene plate to control the stratification height of the hot and cold fluids through the overflow hole 34.

[0063] Specifically, after the heat flow discharged from the calender roll 4 enters the liquid collection groove 28 through the drain hole 7, it is concentrated and flows to the inlet of the heat flow conduit 31 under the directional guidance of the arc-shaped deflector 30. The heat exchange pump group 32 drives the heat flow to conduct heat exchange through the heat flow conduit 31 and enter the transfer tank 35. Subsequently, the cold flow enters the other side of the coolant tank 13 through the overflow hole 34 under the blockage of the partition plate 33.

[0064] One side of the second side plate 3 is provided with a storage groove 25. A part of the cold flow conduit 16 is placed in the storage groove 25, and a limiting block 26 is arranged in the storage groove 25. One side of the limiting block 26 abuts against one side of the cold flow conduit 16.

[0065] Among them, the storage groove 25 refers to the groove structure formed by machining the surface of the second side plate. Specifically, it can be formed by milling or casting processes, and its depth can be one-third to one-half of the thickness of the second side plate, and is used to accommodate the local structure of the cold flow conduit 16. The conduit is fixed inside the second side plate through the physical limiting effect of the groove.

[0066] Among them, the limiting block 26 refers to the rigid fixing part embedded in the storage groove 25. Specifically, a metal block or an engineering plastic block can be adopted, and its height matches the depth of the storage groove. It is fixed to the bottom of the storage groove 25 by bolts or welding, and forms a surface contact with the side of the cold flow conduit 16. This structure restricts the axial and radial displacements of the conduit through mechanical abutment.

[0067] Specifically, when the cold flow conduit is embedded in the receiving groove, its outer wall and the inner wall of the receiving groove form a gap fit, so that the axis of the conduit remains coaxial with the axis of the cold flow injection hole. When the coolant flows through the conduit and generates pressure fluctuations or vibrations during equipment operation, the limit block offsets the sliding tendency of the conduit along the length of the receiving groove through continuous resistance against the side of the conduit. At the same time, the wrapping constraint of the side wall of the receiving groove on the conduit can suppress the swing amplitude of the conduit in the direction perpendicular to the axis, thereby avoiding sealing failure at the connection between the cold flow injection hole and the sealing bearing due to conduit displacement.

[0068] Compared with the existing technology, the conduits in traditional cooling systems are usually directly exposed to the outside of the equipment and are only simply fixed by pipe clamps or straps, which cannot effectively suppress the loose connection caused by high-frequency vibration. However, this solution forms a double rigid fixing mechanism by embedding the conduit into the second side panel and setting a limit block, which reduces the displacement of the conduit under mechanical vibration conditions by about 60%-80%, significantly improving the sealing reliability.

[0069] A protective shell 36 is disposed on one side of the side plate 1 2 and the side plate 2 3 , and a shell cover 37 is turned over and connected to one side of the protective shell 36 .

[0070] Among them, the protective shell 36 refers to the shell structure covering the outside of the side panel, which can be specifically realized by metal stamping parts or injection molding parts. The inner cavity space completely wraps the connection area between the drive component and the hot and cold flow conveying components.
