Technical Field

[0001] This utility model belongs to the technical field of heat dissipation devices, and specifically relates to a bearing housing heat dissipation device based on heat sinks. Background Technology

[0002] When bearings operate under high-speed, heavy-load conditions, a large amount of heat is generated due to friction and the aging of grease and oil. If this heat cannot be dissipated in time, the bearing temperature will rise, accelerating the failure of the lubricating medium, fatigue of metal materials, and aging of seals, thereby shortening the bearing's life.

[0003] However, traditional heat dissipation methods (such as external air cooling, increasing the amount of lubricating oil, and water cooling circulation) have problems such as complex structure, high energy consumption, high maintenance costs, or large space occupation. Therefore, it is necessary to design a bearing housing heat dissipation device based on heat sinks to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0036] like Figures 1 to 4 As shown in the figure, a bearing housing heat dissipation device based on heat sinks according to an embodiment of the present invention is applied to a pump shaft 3, including an upper movable support 6, a lower movable support 7, and fins 8. Specifically, it is applied to a pump, which includes a bearing housing 4 and a pump head 1. The pump head 1 is connected to the end of the bearing housing 4. A seal 2 and a pump shaft 3 are installed inside the bearing housing 4. A heat dissipation fan mounting position 5 is provided on the pump shaft 3 for installing a heat dissipation device. The upper movable support 6 is configured as a semi-circular structure. The lower movable support 7 is configured as a semi-circular structure. The upper movable support 6 and the lower movable support 7 are distributed opposite to each other and sleeved on the pump shaft 3. The lower movable support 7 is detachably connected to the upper movable support 6. The fins 8 are provided on both the upper movable support 6 and the lower movable support 7. Specifically, the size of the heat dissipation device is designed according to the thickness of the pump shaft 3 and the size of the pump chamber. The heat dissipation device consists of two semi-circular upper movable supports 6 and lower movable supports 7, which are clamped to the pump shaft 3. Several fins 8 are embedded on the upper and lower movable supports 6 and 7. The size of the fins 8 can be adjusted according to the size of the pump chamber or the air volume, so that the gap between the heat dissipation device and the bearing housing 4 forms an air flow channel. The air circulation is promoted by the vibration of the equipment itself or the external airflow during operation. The two semi-circles are tightened by bolts 10 and nuts 9 on both sides to tightly hold the pump shaft 3. This heat dissipation device does not require the pump shaft 3 to rotate in any direction and can be used in both forward and reverse directions, which helps to improve the heat dissipation efficiency. Therefore, by installing the upper movable supports 6 and lower movable supports 7 on the pump shaft 3 and using the fins 8 on the upper movable supports 6 and lower movable supports 7, the operating temperature of the bearing housing 4 can be reduced and the life of the bearing housing 4 can be extended; no additional energy is required, and maintenance costs are reduced. Secondly, its compact structure does not occupy extra space, making it suitable for confined installation environments; passive heat dissipation ensures high reliability and eliminates the risk of moving part failures; it is compatible with existing bearing housing designs, resulting in low modification costs. Furthermore, the pump and motor require no disassembly for installation; as long as the space is suitable, quick installation is possible.

[0037] In this embodiment, the heat dissipation device has a simple and compact structure, and can also be designed to be made of plastic or PTFE to adapt to the explosion-proof environment of the chemical industry. Furthermore, the fins 8 can be embedded in the upper movable support 6 and the lower movable support 7, or can be detachably connected to either the upper movable support 6 or the lower movable support 7.

[0038] Optionally, such as Figures 2 to 4As shown, the bearing housing heat dissipation device based on heat sinks also includes nuts 9 and bolts 10. Nuts 9 are connected to both the upper movable support 6 and the lower movable support 7. Bolts 10 are used to connect the nuts 9 of the upper movable support 6 and the nuts 9 of the lower movable support 7. Specifically, nuts 9 are welded to both ends of the upper movable support 6, and nuts 9 are also welded to both ends of the lower movable support 7. When the upper movable support 6 and the lower movable support 7 are distributed opposite each other, two of the four nuts 9 correspond to each other. By setting two bolts 10, with each nut 9 passing through the corresponding two nuts 9, both ends of the upper movable support 6 and the lower movable support 7 can be simultaneously limited, making the upper movable support 6 and the lower movable support 7 form a whole, thereby improving the stability of the heat dissipation device mounted on the pump shaft 3. Furthermore, in the event of damage to the heat dissipation device, it is also convenient to disassemble and replace the upper movable support 6 and the lower movable support 7 by loosening the bolts 10.

[0039] Optionally, such as Figures 2 to 4 As shown, the upper movable support 6 is provided with multiple fins 8, and the lower movable support 7 is provided with multiple fins 8. Specifically, by providing multiple fins 8 on both the upper movable support 6 and the lower movable support 7, the heat dissipation effect is improved.

[0040] Optionally, such as Figure 3 and Figure 4 As shown, the tilt angle of the fins 8 can affect the direction and speed of airflow, thus affecting heat dissipation efficiency. An appropriate tilt angle allows air to flow more smoothly over the fins 8, increasing the heat exchange area and improving heat dissipation efficiency. To adjust the angle of the fins 8, the bearing housing heat dissipation device based on the heat sink also includes a first connecting block 11, a screw 12, and a first connecting nut 13. The first connecting block 11 is rotatably connected to the upper movable support 6 or the lower movable support 7, and the fins 8 are used to connect to the first connecting block 11. The screw 12 is connected to the first connecting block 11, and the screw 12 passes through the upper movable support 6 or the lower movable support 7, with the axial direction of the screw 12 facing a first direction. Specifically, the first direction is the up-down direction. The first connecting nut 13 is threadedly connected to the screw 12. By rotating the first connecting block 11 relative to the upper movable support 6 or the lower movable support 7, and with the fin 8 connected to the first connecting block 11, the fin 8 can be rotated about a first direction as its central axis. By using the screw 12 and the first connecting nut 13, the first connecting block 11 can be fixed after the fin 8 has been adjusted to a first angle. Therefore, by rotating the fin 8 about a first direction as its axis, the first angle of the fin 8 can be easily adjusted, which helps to enhance the heat dissipation effect of the fin 8 according to actual needs.

[0041] Optionally, such as Figure 3 and Figure 4As shown, the bearing housing heat dissipation device based on heat sinks further includes a second connecting block 14, a first connecting screw 15, and a second connecting nut 16. The second connecting block 14 is rotatably connected to the first connecting block 11, and the fins 8 are connected to the second connecting block 14. The first connecting screw 15 passes through the second connecting block 14 and the first connecting block 11 and is threadedly connected to the second connecting nut 16. The axial direction of the first connecting screw 15 faces a second direction, which is perpendicular to the first direction. Specifically, the second direction is the left-right direction. By rotating the second connecting block 14 relative to the first connecting block 11, and with the fins 8 connected to the second connecting block 14, the fins 8 can be rotated around the second direction as the central axis. By setting the first connecting screw 15 and the second connecting nut 16, the second connecting block 14 can be fixed after the second angle of the fins 8 is adjusted. Thus, by rotating the fins 8 around the second direction as the axis, the second angle of the fins 8 can be easily adjusted, which is beneficial for enhancing the heat dissipation effect of the fins 8 according to actual needs.

[0042] Optionally, such as Figure 3 and Figure 4 As shown, the bearing housing heat dissipation device based on heat sinks also includes a second connecting screw 17. The fins 8 are rotatably connected to the second connecting block 14. The second connecting screw 17 passes through the fins 8 and the second connecting block 14, with its axial direction facing a third direction, which is perpendicular to both the first and second directions. Specifically, the third direction is the front-to-back direction. By rotating the fins 8 relative to the second connecting block 14 about the third direction as a central axis, and by providing the second connecting screw 17, the fins 8 can be fixed after a third angle adjustment. Therefore, by rotating the fins 8 about the third direction as an axis, the third angle of the fins 8 can be easily adjusted, which is beneficial for enhancing the heat dissipation effect of the fins 8 according to actual needs.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
