Publication number: 20110038122Abstract: Power electronic devices are solder to a phase change heat spreader using an energetic multilayer foil. This foil may be sandwiched between layers of solder, the first layer in contact with the power electronic devices and the second layer in contact with the phase change heat spreader. When activated, this foil may induce the solder to physically and thermally bond the power electronic devices to the phase change heat spreader. Certain embodiments may also employ energetic multilayer foil to thermally bond the phase change heat spreader to a heat dissipation structure. Other embodiments may employ a phase change heat spreader with an integrated heat dissipation structure. In addition, some embodiments may employ a heat sink as the heat dissipation structure, while other embodiments employ a liquid cooling system.Type: ApplicationFiled: August 12, 2009Publication date: February 17, 2011Applicant: ROCKWELL AUTOMATION TECHNOLOGIES, INC.Inventors: Abdolmehdi Kaveh Ahangar, Steven C.

Patent number: 7880088Abstract: A bus system is disclosed for use with switching devices, such as power electronic devices. The system includes generally parallel bus elements that define electrical reference planes, such as for a dc bus. The bus elements are separated from one another by insulative layers, with additional insulative layers being available for separating the system from other circuit components. Portions of the bus elements are extended or exposed to permit connection to the circuit elements, including packaged switching circuits and energy storage or filtering circuits. The bus system may be conformed to a variety of geometric configurations, and substantially reduces parasitic inductance and total loop inductance in the resulting circuitry.Type: GrantFiled: March 3, 2008Date of Patent: February 1, 2011Assignee: Rockwell Automation Technologies, Inc.Inventors: Lawrence D.

Patent number: 7450388Abstract: EMI shielding is provided for power electronics circuits and the like via a direct-mount reference plane support and shielding structure. The thermal support may receive one or more power electronic circuits. The support may aid in removing heat from the circuits through fluid circulating through the support. The support forms a shield from both external EMI/RFI and from interference generated by operation of the power electronic circuits. Features may be provided to permit and enhance connection of the circuitry to external circuitry, such as improved terminal configurations. Modular units may be assembled that may be coupled to electronic circuitry via plug-in arrangements or through interface with a backplane or similar mounting and interconnecting structures.Type: GrantFiled: September 16, 2003Date of Patent: November 11, 2008Assignee: Rockwell Automation Technologies, Inc.Inventors: Bruce C.

Publication number: 20080266801Abstract: A power electronic module is cooled by a phase change heat spreader or cooling device. The module may include switched or unswitched devices, such as power transistors, diodes, and so forth, forming circuits such as rectifiers, inverters, converters, or the like, or portions of such circuits. Heat is transferred to the heat spreader in which a continuous phase change cycle takes place to cool the circuit components. The heat spreader may extend over an area sufficient to reduce the temperature of the components, and ultimately will render portions of the overall structure more isothermal.Type: ApplicationFiled: April 30, 2007Publication date: October 30, 2008Inventors: Bruce W. Weiss, Neil Gollhardt, Abdolmehdi Kaveh Ahangar, Daniel G. Kannenberg, Steven C. Kaishian

Patent number: 7212406Abstract: A cooling system (11) is provided for electrical components (10, 90) in which passageways (21) are inserted in non-magnetic cores of the electrical components, and in which the passageways (21) provide both inflow and outflow of a cooling medium. The passageways (21) can be formed by drilling holes in a core of an electrical component or by mounting closed-end tubes (16–19) on a base plate-cooling manifold (20) or can be part of a conduit assembly (70). The tubes (16–19, 71) are split-flow closed-end tubes inserted from one end of the electrical component (10, 90). The tubes and passageways (16–19, 21, 71) may be partitioned into two halves or into two concentric portions. O-ring seals (28) are provided around the base of the tubes to seal the areas where the passageways communicate with hollow portions of base plates for supplying the cooling medium.Type: GrantFiled: September 1, 2004Date of Patent: May 1, 2007Assignee: Rockwell Automation Technologies, Inc.Inventors: Steven C. Kaishian, Daniel C. Pixler, Timothy A. Roebke, Scott D. Day, William K. Siebert

Patent number: 7129808Abstract: A cooling system is provided for electrical components in which cooling assemblies (11, 45) are inserted in non-magnetic cores of the electrical components, and in which tubes provide both inflow and outflow of a cooling medium. The non-magnetic cores may be bobbins (30) for an inductor assembly or the core of a capacitor (40). The tubes may form a loop (11) in more than one plane to prevent inducing current in a single turn, or they may be split-flow closed-end tubes (45) inserted from one end of the electrical component. The bobbin cores (31) are also constructed with a non-conductive portion to prevent inducing a current in a single turn of a conductor.Type: GrantFiled: September 1, 2004Date of Patent: October 31, 2006Assignee: Rockwell Automation Technologies, Inc.Inventors: Timothy A.
