Description

Technical Field

[0001] This utility model relates to the field of intelligent electronic management terminal technology, specifically a copper sleeve type liquid-cooled heat dissipation bearing seat with integrated spiral microchannel. Background Technology

[0002] As industrial manufacturing develops towards higher precision, higher speed, and higher power, bearings, as core components of equipment transmission systems, directly determine the overall performance and service life of the equipment through their operational stability and heat dissipation efficiency. In key fields such as automobile manufacturing, aerospace, and precision machine tools, the speed requirements for bearings have increased from the traditional 1000-2000 r / min to 5000-10000 r / min, with a corresponding increase in load intensity. This leads to a significant increase in the rate of frictional heat generation during bearing operation. If the heat cannot be dissipated in time, it can cause problems such as bearing grease failure and accelerated wear of rolling elements. According to industry statistics, equipment failures caused by excessive bearing temperature rise account for more than 35%, directly resulting in economic losses of hundreds of millions of yuan annually.

[0003] Existing liquid-cooled bearing housings mostly have a liquid cooling jacket added to the outside of the bearing housing. The coolant needs to pass through a 10-15mm thick housing shell before it can exchange heat with the outer ring of the bearing. The heat dissipation path is long and the thermal resistance is high, so the heat dissipation efficiency cannot meet the requirements of high-speed operating conditions. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figure 1-4 A copper sleeve type liquid cooling heat dissipation bearing housing with integrated spiral microchannel includes a lower seat 1 and an upper seat 2. The lower seat 1 and the upper seat 2 are both provided with mounting grooves. The inner diameter of the mounting groove matches the outer diameter of the copper sleeve. The copper sleeve installed in the mounting groove is fixed by connecting the lower seat 1 and the upper seat 2.

[0027] The heat dissipation copper sleeve 3 is used to fix the bearing and dissipate heat from the bearing.

[0028] The heat dissipation copper sleeve 3 includes a retaining ring 31. A threaded connector 311 is fixedly connected to the left side of the retaining ring 31. Two symmetrically distributed auxiliary tightening blocks 312 are fixedly connected to the right side surface of the retaining ring 31. A threaded groove 34 is provided at the right end of the inner wall of the heat dissipation copper sleeve 3. The retaining ring 31 is threadedly connected to the heat dissipation copper sleeve 3 through the threaded connector 311. A special gasket 33 is fixedly connected to the contact surface between the retaining ring 31 and the copper sleeve.

[0029] The inner wall of the heat dissipation copper sleeve 3 is provided with a spiral channel 35. The inlet of the spiral channel 35 is fixedly connected to an inlet pipe 36, and the outlet of the spiral channel 35 is fixedly connected to an outlet pipe 37. The ends of the inlet pipe 36 and the outlet pipe 37 away from the heat dissipation copper sleeve 3 are both fixedly connected to quick-connect connectors 38.

[0030] The inlet pipe 36 and the outlet pipe 37 are the same size.

[0031] The heat dissipation copper sleeve 3 has a gasket groove 32 on the left side inside, and a special gasket 33 is fixedly connected inside the gasket groove 32. The diameter of the opening on the left side inside the heat dissipation copper sleeve 3 is smaller than the outer diameter of the bearing outer ring.

[0032] In this embodiment, the bearing is fixed by a heat dissipation copper sleeve 3, and the coolant is directly contacted with the outer ring of the bearing by milling a spiral channel 35 directly on the inner wall of the heat dissipation copper sleeve 3. This multi-end heat dissipation path greatly reduces thermal resistance. Compared with traditional liquid-cooled bearing housings, the heat dissipation efficiency is improved by more than 40%, and the bearing temperature rise can be reduced by 30%, effectively extending the bearing service life. The heat dissipation copper sleeve 3 is made of oxygen-free copper, which has a thermal conductivity much higher than that of traditional bearing housing materials. It can quickly transfer the heat of the outer ring of the bearing to the coolant and prevent heat from accumulating inside the bearing.

[0033] During use, the bearing is embedded inside the heat dissipation copper sleeve 3. Since the diameter of the opening on the left side inside the heat dissipation copper sleeve 3 is smaller than the outer diameter of the bearing outer ring, the position of the bearing outer ring inside the heat dissipation copper sleeve 3 is restricted. The retaining ring 31 is installed and tightened to the heat dissipation copper sleeve 3. The retaining ring 31 is easily disassembled and installed by the setting of the auxiliary tightening block 312. After tightening, the contact part between the bearing outer ring and the inner wall of the heat dissipation copper sleeve 3 is sealed by the setting of two special gaskets 33, which effectively avoids the possibility of coolant leakage. The coolant is easily connected and discharged into the spiral channel 35 by the setting of the inlet pipe 36 and the outlet pipe 37. The external pipe is easily disassembled and installed by the setting of the quick connector 38. The special gaskets 33 are made of oil-resistant and high-temperature resistant rubber material.

[0034] Example 2:

[0035] Please see Figure 1-2 Based on Embodiment 1, this embodiment provides a technical solution: the bottom ends of both sides of the lower base 1 are fixedly connected with fixed edges 11, and fixed holes 12 are symmetrically opened on the surface of the fixed edges 11.

[0036] The top of the lower body 1 is symmetrically provided with connecting holes 13, and a rubber gasket 14 is fixedly connected to the top surface of the lower body 1.

[0037] The upper seat 2 includes bolts 22. Both sides of the bottom end of the upper seat 2 are symmetrically provided with connecting holes 21. The inner diameter of connecting holes 21 and connecting holes 13 is the same. The upper seat 2 is fixedly connected to the lower seat 1 by bolts 22.

[0038] The connecting surfaces of the lower seat 1 and the upper seat 2 are symmetrically provided with a semi-circular groove 4, and the inner diameter of the semi-circular groove 4 matches the outer diameter of the liquid inlet pipe 36 and the liquid outlet pipe 37.

[0039] Both ends of the mounting grooves inside the lower seat 1 and the upper seat 2 are fixedly connected with arc-shaped gaskets 5.

[0040] In this embodiment, the fixed edge 11 facilitates the installation of the bearing seat. During use, the heat dissipation copper sleeve 3 is placed inside the lower seat 1, and the upper seat 2 is connected to the lower seat 1 and fixed by bolts 22, thereby firmly clamping the heat dissipation copper sleeve 3 and preventing the heat dissipation copper sleeve 3 from shaking during bearing use. The arc-shaped shim 5 enhances the friction between the lower seat 1, the upper seat 2 and the heat dissipation copper sleeve 3, thereby enhancing the fixing effect.

[0041] The semi-circular groove 4 provides installation space for the inlet pipe 36 and the outlet pipe 37.
