Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-3, The utility model provides a high-stability automobile air-conditioning compressor clutch pulley technical solution: It includes a clutch pulley body 1, and the clutch pulley body 1 includes a transmission pulley 101, a clutch coil 102 and a pressure plate 103. The transmission pulley 101, the clutch coil 102 and the pressure plate 103 are interference-connected to each other. The interference joints of the transmission pulley 101, the clutch coil 102 and the pressure plate 103 are fitted with sealing rings, so that the sealing rings prevent impurities such as dust and moisture from entering the clutch pulley body 1, thereby keeping the clutch pulley body 1 clean and also helping to reduce additional friction heat caused by impurities. The friction surface of the clutch pulley body 1 is made of a composite material with good wear resistance and thermal conductivity, such as silicon carbide or graphite reinforced plastic, to reduce friction heat and promote heat transfer. The outer periphery of the transmission pulley 101 is provided with heat dissipation holes 104, and there are a plurality of heat dissipation holes 104, which are symmetrically distributed around the outer periphery of the transmission pulley 101.

[0022] A temperature sensor 2 is fixedly installed on the inner side of the rear end of the clutch pulley body 1, so that the temperature of the clutch pulley body 1 can be monitored by the temperature sensor 2. The front end of the clutch pulley body 1 is movably connected with a heat sink 3 for guiding the heat dissipation of the front end of the clutch pulley body 1. The heat sink 3 is made of lightweight and high-strength aluminum alloy or magnesium alloy material, so that the front end of the clutch pulley body 1 can be shielded and protected by the heat sink 3, and the heat dissipation efficiency can be improved by using its good thermal conductivity. A connecting hole 4 is opened through the outer end of the heat sink 3, and the number of the connecting holes 4 is three, respectively. The outer ends of the heat dissipation plate 3 are symmetrically distributed in sequence, and the connecting hole 4 passes through the interior of the front end of the clutch pulley body 1. An internal threaded connecting pipe 5 is fixedly installed at the rear end opening of the connecting hole 4, and a connecting bolt 6 is threadedly connected to the inner wall of the connecting hole 4, so that the heat dissipation plate 3 is fit and fixedly connected to the front end of the clutch pulley body 1 through the connecting bolt 6 and the internal threaded connecting pipe 5.

[0023] Working principle: When in use, the utility model drives the clutch pulley body 1 to rotate through the belt when the automobile engine is running. When the clutch pulley body 1 rotates, the clutch pulley body 1 will be initially cooled through the heat dissipation holes 104. At the same time, when the clutch pulley body 1 rotates, it will drive the heat dissipation plate 3 to rotate. When the heat dissipation plate 3 rotates, it will synchronously drive the vertical heat dissipation fins 7 and the vortex heat dissipation fins 9 to rotate. When the vertical heat dissipation fins 7 and the vortex heat dissipation fins 9 rotate, through the joint action of the vertical heat dissipation fins 7 and the vortex heat dissipation fins 9, the airflow generated by the vehicle's driving and the centrifugal force generated by the clutch pulley body 1's own rotation are utilized, so that the heat generated by the clutch pulley body 1 can be quickly transferred to the heat dissipation plate 3 and discharged through the vertical heat dissipation fins 7 and the vortex heat dissipation fins 9, thereby promoting the rapid dissipation of heat from the clutch pulley body 1, thereby significantly improving the heat dissipation performance, stability and service life of the clutch pulley body 1.
