Radial jet reattachment nozzle heat sink module for cooling electronics

摘要

A radial jet nozzle for use in cooling a subject body. The radial jet nozzle includes a duct communicating with a plenum and a tapered flow diverter body positioned within the duct for comtrollably diverting the flow of a heat transfer medium through the duct. Heat transfer medium flowing through the duct is controllably, radially directed away from a discharge port of the duct. Flow from the discharge port of the radial jet nozzle creates a negative pressure in an area between a head of the diverter body and target surface of the subject body. The negative pressure increases the heat transfer rate which also increases the mass flow rate without damage to the target surface thereby enhancing the convective heat transfer characteristics of the heat transfer medium. The invention also envisions a method for cooling a subject body employing a radial jet nozzle to radially direct the heat transfer medium relative to the target surface to create a negative pressure zone which enhances the performances of the heat transfer device.
