Abstract
A PCV heater including a plug and a heat sink coupled to the plug. The plug and the heat sink define a gas flow path having a first end and a second end. The second end of the gas flow path defines a discharge port and the heat sink is proximate to the discharge port. The heater also includes a heating element coupled to the plug and electrically connectable to a power source. The heating element thermally engages the heat sink to communicate heat from the heating element to the heat sink when the heating element is electrically connected to the power source. A method for manufacturing the PCV heater includes the steps of placing a heat sink into a mold cavity, coupling a heating element to the heat sink, electrically connecting a first lead wire and a second lead wire to the heating element, and providing a high temperature plastic to the mold cavity to overmold the heat sink and the heating element.
