A high-density power converter that benefits from improved packaging techniques and thermal handling capability is provided. The power converter includes a magnetic core. The converter further includes a printed circuit board providing at least one cutout for receiving a portion of the magnetic core. A circuit is magnetically coupled to the magnetic core. A stopper is configured at an edge of the cutout proximate to the circuit to hold the magnetic core at a predefined distance relative to the circuit, thereby meeting a safety distance requirement between the core and the circuit. Advanced thermal management is provided by way of a heat sink assembly to enhance the thermal-handling capability of the converter.

The present invention provides an integrated cooling device employing heat pipes for cooling an electronic component and a method of manufacturing the same. In one embodiment, the integrated cooling device includes a plate couplable to and supportable by the electronic component. The plate has at least one channel therein that presents an enhanced surface area. The cooling device further includes a sealed heat pipe having a heat-receiving portion fitted within the channel such that the enhanced surface area in contact with the heat pipe experiences an increased thermal communication between the plate and the heat pipe. The heat pipe also has a heat-removing portion that is distal from the heat receiving portion. Inside the heat pipe, a fluid, initially located in the heat-receiving portion of the heat pipe as a liquid, receives heat and evaporates to form a vapor that travels to the heat-removing portion. In the heat-removing portion of the heat pipe, the vapor condenses and cycles back o the heat-receiving portion.

The present invention provides a miniature liquid transfer pump. The pump has a housing that includes first and second blocks joinable to form a leak-resistant impeller chamber with a drive shaft aperture, an inlet and an outlet. An impeller is located in the impeller chamber and a micro-motor with a drive shaft extending therefrom is mounted to the housing. The drive shaft on the micro-motor passes through the drive shaft aperture and engages the impeller. The micro-motor drives the impeller to draw liquid through the inlet and eject the liquid through the outlet.
