Abstract:
In one embodiment, an electronic system includes a printed circuit board, one or more packaged semiconductor devices, and a vapor chamber having a top and a bottom and enclosing a sealed cavity that is partially filled with a coolant. The vapor chamber comprises a thermo-conductive and electro-conductive material. The top of the vapor chamber has one or more depressions formed therein, each depression receiving and thermo-conductively connected to at least part of a bottom of a corresponding packaged semiconductor device, which is mounted through a corresponding aperture in the PCB. A heat sink may be thermo-conductively attached to the bottom of the vapor chamber.
Abstract:
The invention relates to a heat sink (1) for cooling an electrical component. The heat sink (1) is used in a power converter device (21), in particular, at least for cooling the power semiconductors (53) present there. The heat sink (1) according to the invention serves for combining two cooling devices. For this purpose, the heat sink is configured in such a way that it has a first cooling device (5) and a contact area (9), which is provided for dissipating thermal energy to a second cooling device (15), or that the heat sink (1) has a first cooling device (5) and a second cooling device (15).
Abstract:
A self-leveling heat sink includes a spring-arm device having at least one aperture and at least one spring-arm is coupled to a substrate. The substrate has at least one package mounted thereon, so that when the spring-arm device is mounted to the substrate the at least one package passes through the at least one aperture. A heat sink operable to remove heat from the at least one package has at least one heat sink post operable to receive a heat sink clip located at the distal end of each of the at least one spring-arms. Each of the at least one spring-arms extending from an inside edge of the at least one aperture and operable to couple the heat sink to the at least one package.
Abstract:
An intercoupling component (10) (e.g. socket or adapter) is provided for increasing the dissipation of heat generated within an integrated circuit (IC) array (12) positioned within the intercoupling component (10), while maintaining a relatively low profile. The intercoupling component (10) includes a heat sink (30) positioned within the package support member (16) and having an upper surface (45) in contact with a lower surface of the integrated circuit package (12). The package support member (16) includes contact terminals (18) disposed within associated openings (20) of the package for electrically connecting the contacting areas of the integrated circuit package (12) to the corresponding connection regions of the substrate (14). The openings (20) extend from an upper surface to an opposite lower surface of the support member (16) and are located in a pattern corresponding to a pattern of the connection contacts. The heat sink (30) may be configured to be removable and replaceable.
Abstract:
In a mounting arrangement for a solid state device (30), the solid state device (30) is maintained between a thermally conductive support body (20) and a thermally conductive cap member (10) which are urged together by a bolt (14) which passes through an elongated slot (12) in an angled surface (16) of the cap member (10) to engage in a threaded opening (23) in an angled surface (24) in the support body (20). A fastener (44) maintains the support body (20) in contact with a metal chassis (50) serving as a heat sink. The fastener (44) also locates a printed circuit board (40) carrying conductors (48) which connect with conductive leads (36) on the solid state device (30). This mounting arrangement enables highly efficient heat dissipation while maintaining the solid state device (30) in a readily replaceable manner. A plurality of individual solid state devices (30) may be located between the support body (20) and the cap member (10).
