[0002] With the rapid development of the automobile industry and the improvement of consumers' requirements for vehicle performance, the heat dissipation structure design of the clutch housing is crucial to its service life and the stable operation of the vehicle. In the prior art, the clutch housing usually achieves heat dissipation by opening heat dissipation holes. Although this method meets the heat dissipation requirements to a certain extent, it also brings a series of problems.

[0003] The existing heat dissipation hole design makes it easy for oil and dirt to enter the clutch housing through the heat dissipation holes during clutch operation. These oil and dirt and debris generated by clutch friction are easily mixed and condensed into sludge in the clutch housing. Once the sludge is formed, it will not only reduce the heat dissipation efficiency of the clutch housing, causing the internal temperature to rise and affect the performance of the clutch; it will also damage the mechanical structure inside the clutch and increase the failure rate. Therefore, it is necessary to propose a heat dissipation structure for the clutch housing. Utility Model Content

A fixing seat 101 is installed outside the housing 1 for fixing the clutch housing on the vehicle.

[0020] On one side of the housing 1, there is provided a fan chamber 102 separated from the interior thereof, and a centrifugal fan 103 is installed in the fan chamber 102. In practical applications, the centrifugal fan 103 can be driven by an external motor or the output end of the engine. It can be understood that when an external motor is used for driving, a control circuit is provided in the vehicle to start the external motor after the working temperature of the clutch reaches a set value; inside the housing 1, there is provided an arc-shaped partition plate 104, and the arc-shaped partition plate 104 and the upper part of the inner wall of the housing 1 are enclosed to form an air guide chamber 105, and one end of the air guide chamber 105 is connected to the fan chamber 102 and the other end is connected to the fan chamber 102. The end is closed; a plurality of openings are arranged on the arc-shaped partition plate 104, and a wind shield 106 is arranged on the inner side of the opening of the arc-shaped partition plate 104. The upper end of the wind shield 106 is inclined toward the fan chamber 102. When the centrifugal fan 103 is working, the external cold air is sucked into the fan chamber 102, and the cold air is introduced into the interior of the clutch housing through the opening of the wind guide chamber 105. The cold air blown out of the fan chamber 102 is evenly distributed inside the clutch housing along the inclined surface of the wind shield 106, so as to improve the heat dissipation effect.

The air containing the debris enters the sedimentation chamber through the air guide groove 401, and its wind speed decreases when flowing between the wavy air guide plates 407. The debris contained in it settles to the bottom of the sedimentation chamber due to gravity, while the clean air flows out through the air guide groove 401 on the other side; a dust collecting box 3 is inserted into the dust storage groove 2 below the sedimentation partition 4. The dust collecting box can be taken out regularly to conveniently clean the oil and debris settled therein.
