Description

technical field [0001] The invention relates to the technical field of a cooling fan controller assembly, in particular to a structure of a high-power brushless cooling fan power module. Background technique [0002] At present, with the increase of automobile spare parts, OEMs have put forward certain requirements for the space of products, and the required technical requirements can be realized in the case of occupying a small space. At the same time, for motor products in the automotive industry, especially engine cooling fan products, because the temperature of the engine compartment is relatively high, under certain driving conditions, especially in a relatively hot and humid environment, the cooling fan works at a high speed. The static pressure of the fan is relatively high, and the current of the corresponding cooling fan system is relatively large. When the electronic protection of the controller fails, the temperature of the controller will be too high, which may c...
