Description

technical field [0001] The invention relates to the technical field of electromagnetic clutches, in particular to a fully temperature-controlled electromagnetic clutch. Background technique [0002] Because some existing equipment will generate heat during work, a cooling device is often provided to control the temperature, so as to ensure the normal operation and service life of the equipment. However, many existing cooling devices are generally started and shut down at the same time as the equipment they serve, and this type of equipment does not need to be in a cooling state all the time, it only needs to avoid its temperature being too high. Solid, this kind of cooling device has the problem of energy waste, in order to solve this problem, some existing cooling devices use electromagnetic clutches and temperature control switches to control the cooling time, such as the Chinese patent No. ZL201420021271.0 discloses a The electromagnetic clutch fan cooling device for eng...

Problems solved by technology

Solid, this kind of cooling device has the problem of energy waste, in order to solve this problem, some existing cooling devices use electromagnetic clutches and temperature control switches to control the cooling time, such as the Chinese patent No. ZL201420021271.0 discloses a The electromagnetic clutch fan cooling device for engineering machinery engines, which is connected to the inner and outer coils of the electromagnet through two temperature control switches to achieve timely cooling and cooling intensity

However, this device only achieves cooling by changing the rotating speed of the fan, and its cooling range is limited, which cannot meet the cooling needs of working for a long time in a hot climate

[0003] In addition, while this type of electromagnetic clutch cools down other equipment, it will increase the temperature of the entire electromagnetic clutch and the temperature of its working environment due to frictional heat generated during frequent clutching and long-term rotation, thereby Affects the stability and service life of the electromagnetic clutch, so a device that can avoid the overheating of the electromagnetic clutch is needed
