One of the radial reinforcing ribs is connected to the inner wall of the bottom case. An oil inlet is provided on one side of the radial reinforcing rib, and an oil outlet is provided on the other side. Flow channels are formed between the remaining radial reinforcing ribs and the inner wall of the bottom case.
[0006] A preferred solution is that a plurality of retaining strips are alternately provided on the inner wall of the bottom case towards the annular reinforcing rib.

[0018] As Figures 1 to 3 shown, an embodiment of the present application provides a heat dissipation structure for oil supply fluid flow, including a bottom shell 10. An annular reinforcing rib 11 is provided at the center of the bottom shell 10. A plurality of radial reinforcing ribs 12 are alternately provided on the peripheral wall of the annular reinforcing rib 11 towards the inner wall of the bottom shell 10. One of the radial reinforcing ribs 12 is connected to the inner wall of the bottom shell 10. An oil inlet 13 is provided on one side of the radial reinforcing rib 12, and an oil outlet 14 is provided on the other side. A flow channel 23 is formed between the remaining radial reinforcing ribs 12 and the inner wall of the bottom shell 10.
[0019] Figure 3 The arrows in [figure] indicate the flow direction of the oil. One end of the flow channel 23 is connected to the oil inlet 13, and the other end is connected to the oil outlet 14. The oil flows into the flow channel 23 from the oil inlet 13 and flows out of the flow channel 23 from the oil outlet 14. The bottom shell 10 is a circular structure. The number of the radial reinforcing ribs 12 can be set as required. In the present utility model, the number of the radial reinforcing ribs 12 is 7. The radial reinforcing ribs 12 make the flow channel 23 form an S shape or a V shape, increasing the length and area of the flow channel 23, increasing the travel of the oil, extending the length of the oil staying in the flow channel 23, and when an external heater is fixed to the bottom shell 10, also increasing the contact area between the oil and the external heater, enabling the heat of the external heater to be quickly taken away.
[0020] As Figures 1 to 3 shown, a plurality of retaining strips 15 are alternately provided on the inner wall of the bottom shell 10 towards the annular reinforcing rib 11. There is a gap between the retaining strips 15 and the peripheral wall of the annular reinforcing rib 11. The retaining strips 15 are inserted between adjacent two radial reinforcing ribs 12. The number of the retaining strips 15 is set as required. In the present utility model, the number of the retaining strips 15 is 5. The retaining strips 15 are inserted between adjacent two radial reinforcing ribs 12, further increasing the length of the flow channel 23, increasing the travel of the oil, extending the length of the oil staying in the flow channel 23, and when an external heater is fixed to the bottom shell 10, enabling the heat of the external heater to be quickly taken away.
[0021] As Figures 1 to 3As shown in the figure, a through hole 16 runs through the center of the bottom shell 10. The annular reinforcing rib 11 is arranged around the through hole 16. A first annular sealing strip 17 is provided on the surface of the annular reinforcing rib 11. A radial sealing strip 18 is provided on the surface of the radial reinforcing rib 12 connected to the inner wall of the bottom shell 10. The first annular sealing strip 17 and the radial sealing strip 18 are of an integral structure. A second annular sealing strip 19 is provided on the inner circumferential wall of the bottom shell 10. When an external heater is connected to the bottom shell 10, the first annular sealing strip 17, the second annular sealing strip 19 and the radial sealing strip 18 are in close contact with the external heater respectively.
[0022] As Figures 1 to 3 shown in the figure, when an external heater is connected to the bottom shell 10, the first annular sealing strip 17, the second annular sealing strip 19 and the radial sealing strip 18 are in close contact with the external heater respectively, and a flow channel 23 forms a closed space. The oil in the flow channel 23 can take away the heat generated by the external heater.
[0023] As Figures 1 to 3 shown in the figure, a oil guiding plate 20 is provided at the oil inlet 13. One end of the oil guiding plate 20 is connected to the inner wall of the bottom shell 10, and the other end points to the annular reinforcing rib 11. The oil guiding plate 20 enables the oil flowing in from the oil inlet 13 to quickly enter the flow channel 23, playing a guiding role.
[0024] As Figures 1 to 3 shown in the figure, a oil distributing limiting boss 21 is provided on the inner wall of the bottom shell 10 facing the annular reinforcing rib 11. A oil distributing channel 22 is formed between the oil distributing limiting boss 21 and the annular reinforcing rib 11. The oil distributing limiting boss 21 is arranged in the middle of the flow channel 23. The oil distributing channel 22 is narrower than the flow channel 23. The oil distributing limiting boss 21 makes the flow rate of the oil different.
[0025] The above are the specific embodiments of the present invention.
