DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Embodiment 1:
[0027] Please refer to Figure 1-3A planetary reducer with good heat dissipation comprises a reducer housing 1, a plurality of supporting legs 3 are fixedly connected to the bottom of the reducer housing 1, an inspection cover 16 is arranged on the rear side of the reducer housing 1, a plurality of heat conducting sheets 2 are arranged on both sides of the reducer housing 1, a cooling cavity 6 is opened inside the reducer housing 1, a drainage hole 4 is opened on the left side of the bottom of the cooling cavity 6, a rubber plug 5 is clamped inside the drainage hole 4, a plurality of foot pads 15 are fixedly connected to the top of the reducer housing 1, a plurality of mounting seats 9 are fixedly connected to the top of the plurality of foot pads 15, a plurality of heat dissipating fins 10 are fixedly arranged inside the mounting seat 9, the plurality of heat dissipating fins 10 are distributed in a linear array inside the mounting seat 9, and the plurality of heat dissipating fins The spacing between 10 is the same, and a heat dissipation copper tube 11 is penetrated inside several heat dissipation fins 10. The heat dissipation copper tube 11 is in the shape of a multi-section bent U-shaped tube. The right side of the heat dissipation copper tube 11 is fixedly connected with a return pipe 12, and the left side of the heat dissipation copper tube 11 is fixedly connected with a pumping pipe 7. A micro water pump 8 is arranged on the surface of the pumping pipe 7. The bottom of the pumping pipe 7 penetrates the top of the reducer housing 1 and extends to the left side of the interior of the cooling chamber 6. The bottom of the return pipe 12 penetrates the top of the reducer housing 1 and extends to the right side of the interior of the cooling chamber 6. An exhaust fan 17 is arranged on the top of the mounting seat 9. A water injection port 13 is opened on the right side of the top of the reducer housing 1, and a water inlet cover 14 is arranged on the rear side of the water injection port 13.
[0028] Working principle: When in use, the staff fills the cooling water into the cooling chamber 6 through the water inlet 13. When the cooling water fills the cooling chamber 6, the water inlet 13 can be closed through the water inlet cover 14. When the planetary reducer is working, the heat generated will be transferred to the cooling water in the cooling chamber 6 through the reducer housing 1. The cooling water will then absorb the heat and the temperature will rise. At this time, the staff starts the micro water pump 8 and the exhaust fan 17. The micro water pump 8 extracts the cooling water in the cooling chamber 6 through the water pump 7 and transports it to the heat dissipation copper tube 11. The cooling water then transfers the heat to the heat dissipation copper tube 11 and the heat dissipation fins. The exhaust fan 17 rotates to exhaust the air inside the mounting seat 9. At this time, under the action of air pressure, the cold air from the outside will enter the mounting seat 9 from the gap at the bottom of the mounting seat 9, and then be exhausted by the exhaust fan 17. The cold air will flow through the surfaces of the heat dissipation fins 10 and the heat dissipation copper tubes 11 when passing through the inside of the mounting seat 9, thereby driving up the temperature of the surfaces of the heat dissipation copper tubes 11 and the heat dissipation fins 10, and then cool the cooling water. The cooled cooling water returns to the cooling chamber 6 through the return pipe 12 for cooling, and the cycle is repeated to improve the heat dissipation effect of the planetary reducer.
[0029] Compared with the related art, the planetary reducer with good heat dissipation provided by the utility model has the following beneficial effects: by setting a water suction pipe 7, a water return pipe 12, a cooling chamber 6, etc. in conjunction with a micro water pump 8, the water in the cooling chamber 6 can be circulated for heat dissipation, thereby improving the water cooling effect of the cooling chamber 6. At the same time, no additional water tank is required, which is convenient for use by staff.
[0030] Embodiment 2:
[0031] Please refer to Figure 1-4 A plurality of supporting legs 3 are fixedly connected to the bottom of the reducer housing 1, an inspection cover 16 is provided on the rear side of the reducer housing 1, a plurality of heat conducting plates 2 are provided on both sides of the reducer housing 1, the plurality of heat conducting plates 2 are distributed in a linear array on both sides of the reducer housing 1, and the sides of the plurality of heat conducting plates 2 close to each other extend to the inside of the cooling cavity 6, a cooling cavity 6 is opened inside the reducer housing 1, a drainage hole 4 is opened on the left side of the bottom of the cooling cavity 6, and a rubber plug 5 is clamped inside the drainage hole 4.
[0032] Working principle: When the cooling chamber 6 is filled with cooling water, the cooling water will wrap the inner shell of the reducer housing 1 along the shape of the cooling chamber 6, which greatly increases the contact area between the cooling water and the reducer housing 1 and improves the heat dissipation efficiency of the planetary reducer. At the same time, one end of the heat conducting sheet 2 extending into the cooling chamber 6 will dissipate the temperature of the cooling water into the air through the other end of the heat conducting sheet 2, further reducing the temperature of the cooling water in the cooling chamber 6 and improving the heat dissipation effect. The cooling water in the cooling chamber 6 can be discharged through the drain hole 4 by pulling out the rubber plug 5 from the drain hole 4, making it convenient to add new cooling water.
[0033] Compared with the related art, the planetary reducer with good heat dissipation provided by the utility model has the following beneficial effects: by setting up a heat conducting plate 2, a cooling chamber 6 and the like for use together, the temperature of the cooling water in the cooling chamber 6 is dissipated into the outside air through the heat conducting plate 2, and the contact area between the cooling water and the reducer housing 1 is greatly increased through the cooling chamber 6, thereby further improving the heat dissipation effect.
[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
