Description

Technical Field

[0001] This application relates to the field of bearing heat dissipation technology, and in particular to a device for enhancing bearing heat dissipation. Background Technology

[0002] A bearing heat dissipation enhancement device is a device or technology used to improve the heat dissipation performance of bearings. It aims to reduce the operating temperature of bearings, extend the service life of bearings, and improve the operating efficiency of equipment. In the prior art, Chinese Patent Application No. CN201510844486.1 discloses a bearing heat dissipation enhancement device, including a bearing oil tank, a thrust head disposed within the bearing oil tank for transmitting axial force from the main shaft to the bearing mirror plate, a cooler and a support plate disposed within the bearing oil tank, and an oil guide chamber located on the outer circumference of the thrust head between the thrust head and the cooler. The oil guide chamber is generally annular, and several guide plates are arranged around the inner sidewall of the oil guide chamber. Each guide plate includes blades and triangular supports connected to the blades. The blades and triangular supports are arranged circumferentially, and an oil passage is formed between the blades and triangular supports of adjacent guide plates. An oil inlet is located at one end of the blade, and an oil outlet is located at one end of the triangular support. The openings of the oil inlet are located at the upper and lower ends of the blade, respectively opening upwards and downwards along the axial direction of the oil guide chamber, and the oil outlet is located facing outwards from the oil guide chamber. This invention has a simple structure, is easy to install, and can effectively enhance cooling efficiency. This solves the problem that during low-speed operation, the lubricating oil inside the oil tank has low fluidity, and the hot oil does not have enough power to flow to the cooler for cooling. As a result, the hot oil continues to participate in lubrication, forming a short circuit, and the hydrodynamic oil film becomes thinner, which is not conducive to the long-term reliable and stable operation of the bearing.

[0003] In the process of realizing this application, the inventors discovered the following problems with the prior art: the above-mentioned device dissipates heat from the bearing by using oil to drive heat dissipation. Therefore, the bearing requires an additional external device to facilitate the driving of the oil so as to move the oil volume and achieve the heat dissipation effect. In addition, the above-mentioned device uses a single heat dissipation medium, which is not conducive to active or passive heat dissipation, and thus not conducive to the start-up of the external device. Summary of the Invention

[0004] The purpose of this application is to provide a device for enhancing bearing heat dissipation.

[0005] The enhanced bearing heat dissipation device provided in this application adopts the following technical solution: A bearing heat dissipation enhancement device includes a lower bearing housing, an upper bearing housing, a bearing body, a first heat dissipation assembly, and a second heat dissipation assembly. The lower bearing housing is connected to the upper bearing housing via a first threaded hole and a first bolt. A lower arc-shaped limiting groove is formed on the upper end face of the lower bearing housing, and an upper arc-shaped limiting groove is formed on the bottom end face of the upper bearing housing. The lower and upper bearing housings are connected to the bearing body via the lower and upper arc-shaped limiting grooves. The first heat dissipation assembly is disposed inside the lower and upper bearing housings, and the second heat dissipation assembly is disposed on both sides of the bearing body. The first heat dissipation assembly includes thermally conductive copper. The bearing housing comprises a heat-conducting copper plate and a heat-conducting copper pillar. Two sets of heat-conducting copper plates are fitted together on the surfaces of the lower and upper arc-shaped limiting grooves. Heat-conducting copper plates are also fitted together with heat-conducting copper pillars. A first heat dissipation port is provided on the side end face of the lower bearing housing, and a second heat dissipation port is provided on the side end face of the upper bearing housing. The heat-conducting copper pillars are connected to a liquid storage tank via copper pipes, and the liquid storage tank is connected to heat dissipation fins. The ventilation openings of the first and second heat dissipation ports on the lower and upper bearing housings are perpendicular to each other. The heat dissipation fins on the lower and upper bearing housings are also perpendicular to each other.

[0006] By adopting the above technical solution, the bearing is cooled by the first and second heat dissipation components in the lower and upper bearing housings. The heat-conducting copper sheet is installed in close contact with the bearing body, which facilitates heat transfer within the bearing body. The heat generated by the bearing body is transferred to the heat-conducting copper sheet, which in turn transfers it to the heat-conducting copper pillar. The heat is then transferred through a copper pipe to the liquid storage tank, and finally to the heat dissipation fins, thus facilitating heat dissipation and achieving rapid cooling of the bearing. A first and second heat dissipation port are also provided, facilitating heat dissipation from the heat dissipation fins. Furthermore, the different through-hole directions of the first and second heat dissipation ports facilitate rapid heat dissipation of the bearing without requiring additional cooling devices.

[0007] The second heat dissipation component includes an arc-shaped heat sink and a heat dissipation spiral groove. The lower arc-shaped limiting groove and the upper arc-shaped limiting groove are provided with plate-shaped limiting grooves on both sides. The arc-shaped heat sink is limited and connected to the lower arc-shaped limiting groove and the upper arc-shaped limiting groove through the plate-shaped limiting grooves. Several sets of arc-shaped heat sinks are provided, and a heat dissipation spiral groove is provided on the side of the several sets of arc-shaped heat sinks away from the lower arc-shaped limiting groove and the upper arc-shaped limiting groove.

[0008] By adopting the above technical solution, the lower arc-shaped limiting groove and the upper arc-shaped limiting groove are connected to the arc-shaped heat sink by the plate-shaped limiting groove, and the arc-shaped heat sink is installed on both sides of the bearing body, so as to facilitate the heat generated by the bearing body to be transferred to the arc-shaped heat sink. Furthermore, since the side end face of the arc-shaped heat sink is provided with a heat dissipation spiral groove, the contact area is increased, which facilitates the heat dissipation of the bearing body.

[0009] The inner sides of both the lower and upper bearing seats are provided with a first heat dissipation assembly, and the heat-conducting copper sheets, heat-conducting copper pillars, copper pipes and liquid storage tanks in the first heat dissipation assembly are arranged symmetrically. The inner diameter surfaces of the two sets of heat-conducting copper sheets are in contact with the outer diameter surfaces of the bearing body, and the heat-conducting copper sheets and the bearing body are at the same center.

[0010] By adopting the above technical solution, the heat-conducting copper sheets, heat-conducting copper pillars, copper pipes and liquid storage tanks are symmetrically arranged. In order to facilitate the fixing of the bearing body, the inner diameter surfaces of the two sets of heat-conducting copper sheets are in contact with the outer diameter surfaces of the bearing body, and the heat-conducting copper sheets and the bearing body are at the same center. Furthermore, the wrapping arrangement method facilitates the lower bearing seat and the upper bearing seat to dissipate heat through the first heat dissipation component and the second heat dissipation component.

[0011] The first heat dissipation assembly has a phase change coolant in the inner cavity of the liquid storage tank. The first heat dissipation assembly has five sets of copper pipes, and the inner cavity of the copper pipes is equipped with a one-way valve. The one-way valves of the two outermost sets of copper pipes have the opposite output direction to the one-way valves of the other three sets of copper pipes. The heat-conducting copper pillars installed in the lower bearing seat and the upper bearing seat form a connected structure. The five sets of heat-conducting copper pillars form a closed loop through the one-way valves, copper pipes and liquid storage tank.

[0012] By adopting the above technical solution, the heat-conducting copper column forms a closed loop through a one-way valve, a copper tube, and a liquid storage tank. Since the heat-conducting copper column has a hollow structure and forms a connected structure through the copper tube, the liquid storage tank, and the heat dissipation fins, and the inner cavity of the copper tube is equipped with a one-way valve, the output direction of the one-way valves of the two outermost sets of the copper tube cavities is opposite to that of the other three sets of copper tube cavities, which facilitates the movement of the phase change coolant and facilitates the flow of the phase change coolant, thereby facilitating the heat dissipation of the bearing body.

[0013] The inner walls of the thermally conductive copper pillars, copper pipes, liquid storage tanks, and heat dissipation fin cavities are provided with thermally conductive capillary columns, which are arranged at an angle.

[0014] By adopting the above technical solution, since the thermally conductive copper pillars, copper pipes, liquid reservoirs and heat dissipation fins are all hollow structures, it is convenient to install thermally conductive capillary columns on the inner walls of the thermally conductive copper pillars, copper pipes, liquid reservoirs and heat dissipation fins, which facilitates the contact between the phase change coolant and the thermally conductive copper pillars, copper pipes, liquid reservoirs and heat dissipation fins, thereby facilitating the heat dissipation of the bearing body.

[0015] The second heat dissipation component has four sets of arc-shaped heat sinks, and two of the sets of arc-shaped heat sinks have interfaces on their contact surfaces, and sealing rings are provided at the edges of the arc-shaped heat sinks.

[0016] By adopting the above technical solution, since there are four sets of arc-shaped heat sinks, and the contact surfaces of two sets of arc-shaped heat sinks are provided with interfaces, and the edges of the arc-shaped heat sinks are provided with sealing rings, it is easier to ensure the sealing of the bearing body, thereby facilitating the heat dissipation of the bearing body through the first heat dissipation component and the second heat dissipation component.

[0017] The lower bearing housing is provided with second threaded holes and second bolts on both sides, and the lower bearing housing is bolted to the base through the second threaded holes and second bolts.

[0018] By adopting the above technical solution, the lower bearing housing and the upper bearing housing can be connected through the first threaded hole and the first bolt, while the lower bearing housing and the upper bearing housing can be further fixed through the second threaded hole and the second bolt, thereby facilitating the stability of the lower bearing housing, the upper bearing housing and the bearing body, and thus facilitating heat dissipation of the bearing body.

[0019] In summary, this application includes at least one of the following beneficial technical effects: In use, this enhanced bearing heat dissipation device utilizes the first and second heat dissipation components in the lower and upper bearing housings to dissipate heat from the bearing. The heat-conducting copper fins are installed in close contact with the bearing body, ultimately transferring heat from the bearing body to the heat-conducting copper fins, which in turn transfer heat to the heat-conducting copper pillars. The heat from the copper pillars is then transferred to the liquid storage tank via copper pipes, and finally to the heat dissipation fins, achieving rapid cooling of the bearing. Simultaneously, a first and second heat dissipation port are provided, which dissipate heat from the heat dissipation fins. Because the through-hole directions of the first and second heat dissipation ports are different, rapid heat dissipation of the bearing is facilitated, eliminating the need for additional heat dissipation devices. The lower and upper arc-shaped limiting grooves are connected to arc-shaped heat dissipation fins using plate-shaped limiting grooves. These arc-shaped heat dissipation fins are installed on both sides of the bearing body, facilitating the transfer of heat generated by the bearing body to the arc-shaped heat dissipation fins. Furthermore, the side end faces of the arc-shaped heat dissipation fins have heat dissipation spiral grooves, increasing the contact area for further heat dissipation from the bearing body.

[0020] In use, the enhanced bearing heat dissipation device features symmetrically arranged heat-conducting copper sheets, heat-conducting copper pillars, copper pipes, and a liquid storage tank, facilitating the fixation of the bearing body. The inner diameter surfaces of the two sets of heat-conducting copper sheets are in contact with the outer diameter surfaces of the bearing body, and the heat-conducting copper sheets and the bearing body are at the same center. This wrap-around arrangement facilitates heat dissipation between the lower and upper bearing seats through the first and second heat dissipation components. The heat-conducting copper pillars form a closed loop using one-way valves, copper pipes, and a liquid storage tank. Because the heat-conducting copper pillars have a hollow structure and are connected through copper pipes, a liquid storage tank, and heat dissipation fins, and because the inner cavity of the copper pipes is equipped with one-way valves, the one-way valves in the two outermost sets of copper pipes have opposite output directions to the one-way valves in the other three sets of copper pipes. This allows the phase change coolant to move between each other, facilitating the flow of the phase change coolant and heat dissipation from the bearing body.

[0021] When in use, this enhanced bearing heat dissipation device features hollow structures for the thermally conductive copper pillars, copper pipes, liquid reservoir, and heat dissipation fins. This allows for the installation of thermally conductive capillary columns on the inner walls of these components, facilitating contact between the phase change coolant and the thermally conductive copper pillars, copper pipes, liquid reservoir, and heat dissipation fins, thus promoting heat dissipation from the bearing body. Four sets of arc-shaped heat dissipation fins are provided, with interfaces at the contact surfaces of two sets of fins. Sealing rings are also provided at the edges of the arc-shaped heat dissipation fins to ensure the sealing of the bearing body. The first and second heat dissipation components dissipate heat from the bearing body. The first threaded hole and the first bolt facilitate the connection between the lower and upper bearing seats, while the second threaded hole and the second bolt further secure the lower and upper bearing seats, maintaining the stability of the lower and upper bearing seats and the bearing body, thereby facilitating heat dissipation from the bearing body.

Detailed Implementation

[0023] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 This application will be described in further detail below.

[0024] Example: A bearing heat dissipation enhancement device includes a lower bearing housing 1, an upper bearing housing 2, a bearing body 3, a first heat dissipation component 4, and a second heat dissipation component 5. The lower bearing housing 1 is connected to the upper bearing housing 2 via a first threaded hole 6 and a first bolt 7. A lower arc-shaped limiting groove 8 is carved on the upper end face of the lower bearing housing 1, and an upper arc-shaped limiting groove 9 is carved on the bottom end face of the upper bearing housing 2. The lower bearing housing 1 and the upper bearing housing 2 are connected to the bearing body 3 via the lower arc-shaped limiting groove 8 and the upper arc-shaped limiting groove 9. A first heat dissipation component is provided inside the lower bearing housing 1 and the upper bearing housing 2. Component 4, the bearing body 3 has a second heat dissipation component 5 on both sides. The first heat dissipation component 4 includes a heat-conducting copper sheet 41 and a heat-conducting copper pillar 42. Two sets of heat-conducting copper sheets 41 are provided, and the two sets of heat-conducting copper sheets 41 are attached to the surfaces of the lower arc-shaped limiting groove 8 and the upper arc-shaped limiting groove 9. The heat-conducting copper sheets 41 are attached to the heat-conducting copper pillar 42. A first heat dissipation port 43 is carved out on the side end face of the lower bearing seat 1, and a second heat dissipation port 44 is carved out on the side end face of the upper bearing seat 2. The heat-conducting copper pillar 42 is connected to a liquid storage tank 46 through a copper pipe 45. The bearing is connected to a heat dissipation fin 47. The ventilation openings of the first heat dissipation port 43 and the second heat dissipation port 44 installed on the lower bearing seat 1 and the upper bearing seat 2 are perpendicular to each other. The heat dissipation fin 47 installed on the lower bearing seat 1 and the upper bearing seat 2 are perpendicular to each other. The bearing is cooled by the first heat dissipation component 4 and the second heat dissipation component 5 in the lower bearing seat 1 and the upper bearing seat 2. The heat-conducting copper plate 41 is attached to the bearing body 3 to facilitate heat transfer in the bearing body 3. The heat generated by the bearing body 3 is transferred to the heat-conducting copper plate 41, the heat-conducting copper plate 41 is transferred to the heat-conducting copper column 42, and the heat-conducting copper column 42 is transferred to the liquid storage tank 46 through the copper pipe 45. Finally, the heat is transferred to the heat dissipation fin 47, which facilitates heat dissipation and achieves the effect of rapid cooling of the bearing. The first heat dissipation port 43 and the second heat dissipation port 44 are provided to dissipate heat from the heat dissipation fin 47. Since the through-hole directions of the first heat dissipation port 43 and the second heat dissipation port 44 are different, it is convenient for the bearing to dissipate heat quickly without the need for additional heat dissipation devices.

[0025] The second heat dissipation component 5 includes an arc-shaped heat sink 51 and a heat dissipation spiral groove 52. A sheet-like limiting groove 53 is provided on both sides of the lower arc-shaped limiting groove 8 and the upper arc-shaped limiting groove 9. The arc-shaped heat sink 51 is limited and connected to the lower arc-shaped limiting groove 8 and the upper arc-shaped limiting groove 9 through the sheet-like limiting groove 53. Several groups of arc-shaped heat sinks 51 are provided, and a heat dissipation spiral groove 52 is provided on the side of each group of arc-shaped heat sinks 51 away from the lower arc-shaped limiting groove 8 and the upper arc-shaped limiting groove 9. The arc-shaped heat sink 51 is installed on both sides of the bearing body 3, facilitating the transfer of heat generated by the bearing body 3 to the arc-shaped heat sink 51. Furthermore, since the side end face of the arc-shaped heat sink 51 has a heat dissipation spiral groove 52, the contact area is increased, thereby facilitating heat dissipation. To dissipate heat from the bearing body 3, a first heat dissipation assembly 4 is provided on the inner side of both the lower bearing seat 1 and the upper bearing seat 2. The heat-conducting copper sheets 41, heat-conducting copper pillars 42, copper pipes 45, and liquid storage tanks 46 in the first heat dissipation assembly 4 are arranged symmetrically. The inner diameter surfaces of the two sets of heat-conducting copper sheets 41 are in contact with the outer diameter surfaces of the bearing body 3, and the heat-conducting copper sheets 41 and the bearing body 3 are at the same center. The heat-conducting copper sheets 41, heat-conducting copper pillars 42, copper pipes 45, and liquid storage tanks 46 are arranged symmetrically. In order to facilitate the fixing of the bearing body 3, the inner diameter surfaces of the two sets of heat-conducting copper sheets 41 are in contact with the outer diameter surfaces of the bearing body 3, and the heat-conducting copper sheets 41 and the bearing body 3 are at the same center. The wrapping arrangement method facilitates heat dissipation from the lower bearing seat 1 and the upper bearing seat 2 through the first heat dissipation assembly 4 and the second heat dissipation assembly 5.

[0026] The inner cavity of the liquid storage tank 46 in the first heat dissipation assembly 4 is filled with phase change coolant 10. Five sets of copper pipes 45 are arranged in the first heat dissipation assembly 4, and one-way valves 11 are installed inside the inner cavity of each copper pipe 45. The one-way valves 11 in the inner cavities of the two outermost sets of copper pipes 45 have opposite output directions to the one-way valves 11 in the inner cavities of the other three sets of copper pipes 45. The heat-conducting copper pillars 42 installed in the lower bearing seat 1 and the upper bearing seat 2 form a connected structure. The five sets of heat-conducting copper pillars 42 form a closed loop through the one-way valves 11, copper pipes 45, and the liquid storage tank 46. The thermally conductive copper pillars 42, copper pipes 45, liquid reservoir 46, and heat dissipation fins 47 are all hollow structures, facilitating the installation of thermally conductive capillary columns 12 on the inner walls of these structures. This allows the phase change coolant 10 to contact the thermally conductive copper pillars 42, copper pipes 45, liquid reservoir 46, and heat dissipation fins 47, thus facilitating heat dissipation from the bearing body 3. The inner walls of the cavities of the thermally conductive copper pillars 42, copper pipes 45, liquid reservoir 46, and heat dissipation fins 47 are equipped with thermally conductive capillary columns 12, and the thermally conductive capillary columns 12 are inclined... The second heat dissipation assembly 5 is arranged at an angle, with four sets of arc-shaped heat sinks 51. Two sets of arc-shaped heat sinks 51 have interfaces 13 on their contact surfaces, and sealing rings are provided at the edges of the arc-shaped heat sinks 51. The lower bearing seat 1 has second threaded holes 14 and second bolts 15 on both sides, and the lower bearing seat 1 is bolted to the base 16 through the second threaded holes 14 and the second bolts 15. Since there are four sets of arc-shaped heat sinks 51, and two sets of arc-shaped heat sinks 51 have interfaces 13 on their contact surfaces, and sealing rings are provided at the edges of the arc-shaped heat sinks 51, it is easy to ensure the sealing of the bearing body 3, and to facilitate heat dissipation of the bearing body 3 through the first heat dissipation assembly 4 and the second heat dissipation assembly 5. The first threaded hole 6 and the first bolt 7 facilitate the connection between the lower bearing seat 1 and the upper bearing seat 2. At the same time, the second threaded hole 14 and the second bolt 15 facilitate the further fixation of the lower bearing seat 1 and the upper bearing seat 2, so as to maintain the stability of the lower bearing seat 1, the upper bearing seat 2 and the bearing body 3, and facilitate heat dissipation of the bearing body 3.

[0027] The implementation principle of this application embodiment is as follows: the bearing is cooled by the first heat dissipation component 4 and the second heat dissipation component 5 in the lower bearing seat 1 and the upper bearing seat 2. The heat-conducting copper plate 41 is attached to the bearing body 3. The heat generated by the bearing body 3 is transferred to the heat-conducting copper plate 41, which in turn transfers the heat to the heat-conducting copper pillar 42. The heat-conducting copper pillar 42 then transfers the heat to the liquid storage tank 46 through the copper pipe 45, and finally transfers the heat to the heat dissipation fins 47. This facilitates heat transfer in the bearing body 3. A first heat dissipation port 43 and a second heat dissipation port 44 are also installed. The heat dissipation fins 47 are cooled by the first heat dissipation port 43 and the second heat dissipation port 44. Since the through-hole directions of the first heat dissipation port 43 and the second heat dissipation port 44 are different, it facilitates rapid heat dissipation of the bearing without requiring additional cooling devices. Simultaneously, by increasing the contact area between the heat dissipation spiral groove 52 and the air, it facilitates heat dissipation of the bearing body 3, thus enabling auxiliary heat dissipation. The heat-conducting copper plates 41, heat-conducting copper pillars 42, copper pipes 45, and liquid storage tank 46 are arranged symmetrically, and the inner diameter surfaces of the two sets of heat-conducting copper plates 41 are parallel to the outer diameter surfaces of the bearing body 3. The surfaces are in close contact, and the heat-conducting copper sheet 41 is centered on the bearing body 3. The wrapping arrangement facilitates heat dissipation between the lower bearing seat 1 and the upper bearing seat 2 via the first heat dissipation assembly 4 and the second heat dissipation assembly 5. Simultaneously, the heat-conducting copper pillar 42, copper pipe 45, liquid reservoir 46, and heat dissipation fins 47 all have hollow structures. The heat-conducting copper pillar 42 is connected to the copper pipe 45, liquid reservoir 46, and heat dissipation fins 47. A one-way valve 11 is installed inside the copper pipe 45. The one-way valves 11 inside the outermost two sets of copper pipes 45 are connected to the inner cavities of the other three sets of copper pipes 45. The one-way valves 11 have opposite output directions so that the phase change coolant 10 can move relative to each other, allowing the phase change coolant 10 to circulate and dissipate heat from the bearing body 3. At the same time, heat-conducting capillary columns 12 are installed on the inner walls of the heat-conducting copper pillars 42, copper pipes 45, liquid reservoir 46 and heat dissipation fins 47, so that the phase change coolant 10 can contact the heat-conducting copper pillars 42, copper pipes 45, liquid reservoir 46 and heat dissipation fins 47. The sealing of the bearing body 3 is ensured by the interface 13 and the sealing ring, so that the first heat dissipation component 4 and the second heat dissipation component 5 can dissipate heat from the bearing body 3.
