摘要:
A thermal management system for cooling a heat generating component of a Magnetic Resonance Imaging (MRI) apparatus includes at least one heat pipe having a portion disposed proximate the heat generating component, such as a gradient coil and/or RF coil. When heat is removed from the component, a working fluid in a relatively hotter end of the heat pipe vaporizes and travels toward a relatively colder end of the heat pipe. The colder end may be operatively coupled to a heat sink for removing the heat from the colder end and increase the overall efficiency of the system. The heat pipe may be disposed along a horizontal, a vertical direction and/or along a diagonal of the heat generating component.

摘要:
An apparatus for removing heat comprises a heat sink having a cavity, and a synthetic jet stack comprising at least one synthetic jet mounted within the cavity. At least one rod and at least one engaging structure to provide a rigid positioning of the at least one synthetic jet with respect to the at least one rod. The synthetic jet comprises at least one orifice through which a fluid is ejected.
摘要:
A heat sink with distributed jet cooling is provided. The heat sink includes a base for thermal connection to at least one heated object, an array of fins thermally coupled to the base, and at least one multi-orifice synthetic jet or multiple single orifice jets disposed on a side of the array of fins. A heat sink with distributed and integrated jet cooling is also provided and includes a base and an array of fins. Respective ones of at least a subset of the fins comprise a synthetic jet configured to eject an ambient fluid into an ambient environment of the fins and base. Another heat sink with distributed and integrated jet cooling is provided and includes a base, an array of fins and multiple synthetic jets coupled to respective ones of the fins. The synthetic jets are provided for at least a subset of the fins.
