Abstract
A heat spreader for a resistive element is provided, the heat spreader having a body portion that is arranged over a top surface of the resistive element and electrically insulated from the resistive element. The heat spreader also includes one or more leg portion that extends from the body portion and are associated with the heat sink in a thermally conductive relationship.
Claims19
A heat spreader for a resistive element mounted on a heat sink, the heat spreader comprising:
- a single-piece body arranged over and covering a top surface of the resistive element and electrically insulated from the resistive element, the body comprising opposite ends forming legs on opposite sides of the resistive element extending toward and associated with the heat sink in a thermally conductive relationship;
- a thermal interface material comprising an adhesive bonding a top surface of the resistive element to the body and mounting the resistive element to the heat sink, the thermal interface material being thermally conductive and electrically non-conductive.
A method for dissipating heat from a resistive element, the method comprising:
- mounting the resistive element on a heat sink via a thermal interface material comprising an adhesive, the thermal interface material being thermally conductive and electrically non-conductive;
- providing a heat spreader having a single-piece body, the body comprising opposite ends forming legs;
- positioning the legs on opposite sides of the resistive element;
- associating the legs with the heat sink in a thermally conductive relationship;
- and,
- bonding a top surface of the resistive element to the body via a thermal interface material comprising an adhesive, the thermal interface material being thermally conductive and electrically non-conductive.
