Abstract: The present invention relates to a blower dryer appliance typically used for drying and styling hair. When electrically activated, these appliances virtually always route electrical power to the fan or blower motor prior to or simultaneously with the heating element(s). Semiconducting switching devices used for regulating, controlling and/or switching electrical power generate waste heat that must be dissipated. Typically, heat is conducted and/or channeled away from the semiconducting switching device through a heat sink which is thermodynamic-mechanically coupled to the device. The greater the coverage area of the heat sink, the more waste heat can be dissipated depending on the ability of the heat sink to make contact with cooler, ambient air. This adds costs to the dryer/blower for engineering the heat sink, cost of the sink itself, and necessary design changes in the dryer/blower for accommodating the sink.
