Cooling hood for circuit board

Semiconductor devices are currently in widespread use in a variety of electronic components. Semiconductor devices may be used for a variety of reasons, such as to retain information, as in a non-volatile memory device, or to perform a calculation, such as in a microprocessor or in a digital signal processor. Semiconductor devices consume a certain amount of power to perform tasks. With the continuing emphasis on miniaturization and enhanced performance, such as a higher operating frequency, the amount of power consumed, and hence, the heat generated by a semiconductor device, has steadily been increasing. The heat generated by a semiconductor device can be so intense that the semiconductor device itself could become damaged or fail. Therefore, in some instances, it has become necessary to employ devices to dissipate the heat generated by a semiconductor device. A cooling hood for a circuit board is provided. The circuit board includes at least one semiconductor device. The cooling hood includes a duct mounted onto the circuit board and surrounding at least a portion of the semiconductor device. The duct forms an inlet and an outlet. A cooling medium enters the duct through the inlet and exits the duct through the outlet.
