  • Patent number: 10462941
    Abstract: A heat sink assembly for a power module is provided. The assembly includes a main body having a first cooling circuit and a second cooling circuit. The first cooling circuit includes a first plurality of channels, at least one first end channel, at least one second end channel, a first inlet, and a first outlet. The first cooling circuit is adapted to provide a first flow of a coolant through the main body. The second cooling circuit includes a second plurality of passages, at least one first end passage, at least one second end passage, a second inlet, and a second outlet. The second cooling circuit is adapted to provide a second flow of the coolant through the main body. The first cooling circuit and second cooling circuit is adapted to provide a cross flow of the first flow and second flow through the main body respectively.

  • Patent number: 9504186
    Abstract: A cold plate for a power circuit is disclosed. The power circuit includes a plurality of transistors and each of the plurality of transistors includes a plurality of dies. The cold plate includes a liquid cooling system that includes a plurality of cooling channels and each of the plurality of cooling channels is aligned with at least one die. The liquid cooling system includes a heat sink associated with each of the plurality of cooling channels. The cold plate further includes a plurality of heat pipes, wherein each of the plurality of heat pipes is aligned with at least one of the plurality of cooling channels and at least one die. Each heat pipe includes a wick lining an interior of the heat pipe, a vapor flow area, and a fluid.

  • Patent number: 8883412
    Abstract: A size standard, kit includes a size standard, method of defining a size standard and method of analysis using a size standard. The size standard is intended to include size standard elements which have a size greater than and/or less than and/or different from the components of a sample which are to be sized. This means that the same characteristic unit, such as a dye, can be used to label the component and the size standard. A further characteristic unit, from amongst a limited number of such characteristic units is liberated from use only on size standards for use on components. The method is therefore particularly useful in multiplex amplification of STRs.
