Problems solved by technology
At present, there is a smooth wall between the active plate and the outer shell of the traditional clutch, and the flow of silicone oil in the shell is homogeneous laminar flow, which greatly limits the ability of silicone oil to conduct convective heat dissipation on the surface of the shell.

Abstract
The invention relates to the field of automobile engine cooling systems, and provides a silicone oil fan clutch with heat dissipation grooves. A plurality of heat dissipation fins are arranged on theouter end face, making contact with silicone oil, of an outer shell; a plurality of circles of concentric laminar flow grooves and a plurality of flow guide grooves communicating with all the laminarflow grooves are formed in the inner end face of the outer shell; and the plurality of heat dissipation grooves communicating with the laminar flow groove in the outermost circle are further formed inthe inner side wall of the outer shell. Compared with the prior art, according to the silicone oil fan clutch with the heat dissipation grooves, the heat dissipation grooves communicating with the laminar flow groove in the outermost circle are formed in the inner side wall of the outer shell, laminar flow silicone oil in the laminar flow grooves enters the heat dissipation grooves, laminar flowflowing of the silicone oil is forcibly changed into turbulent flow, and the heat dissipation capacity of the outer shell can be remarkably improved.
Description
technical field [0001] The invention relates to the field of automobile engine cooling systems, more specifically to a silicone oil fan clutch with a heat dissipation groove. Background technique [0002] Compared with the traditional cooling fan, the silicone oil fan clutch can automatically adjust the fan speed according to the requirements of controlling the temperature, so that the engine can work at the best working temperature, so it has the advantages of energy saving, noise reduction, emission reduction and prolonging the life of the engine. When the silicone oil fan clutch is working, the torque is transmitted between the master and the driven parts by the silicone oil, but due to the slip between the master and the driven parts, that is, the friction of the silicone oil will generate a lot of heat. The maximum heat dissipation capacity is the slip heat capacity of the clutch. An indicator that limits the torque limit of the clutch driving is the limit slip thermal...
