PROBLEM TO BE SOLVED: To dissipate heat generated from an incorporated electronic component. SOLUTION: A circuit board 61, spacer substrates 63-1 and 63-2 and a circuit board 62 where the electronic component 64 is disposed are sequentially laminated on an electronic circuit board 51 from the top. The spacer substrate 63-1, the electronic circuit 64 and the spacer substrate 63-2 are sequentially arranged and connected onto an outermost face 62a of the circuit board 62 from the left. A through hole 65 passing from an uppermost face 61a of the circuit board 61 to a lowermost face 61b is formed right above the electronic component 64 arranged and connected to the circuit board 62 in the circuit board 61. An inner part of the through hole 65 and a part between the through hole 65 and the electronic component 64 are filled with heat dissipating resin 66 so that it covers an upper face 64a of the electronic component 64. This technology can be applied to the electronic circuit board where the electronic component is incorporated between two or more circuit boards. COPYRIGHT: (C)2006,JPO&NCIPI

Methods and apparatus for implementing a synthetic jet to cool a device are provided. Examples of the techniques keep a device case cool enough to be hand-held, while allowing a higher temperature of a circuit component located in the case, to maximize circuit performance. In an example, provided is a mobile device including a synthetic jet configured to transfer heat within the mobile device. The synthetic jet can be embedded in a circuit board inside the mobile device such that the circuit board defines at least a portion of a chamber of the synthetic jet and defines an orifice of the synthetic jet. The device case can define at least one fluid channel inside the mobile device. Also, the circuit board can define a synthetic jet outlet configured to direct a fluid at the at least one fluid channel. Also provided are methods for controlling a synthetic jet.
Abstract:
Micro-hole structures are described herein that may be implemented for device ventilation, protection, and design. The micro-hole structures include multiple micro-holes that are imperceptible to users at ordinary viewing angles and distances, and are thus porous structures that appear to be solid. A micro-hole structure may be formed as a housing of a device or as a structure to be attached to the housing of the device. A device with a micro-hole structure housing enables thermal ventilation from heat-producing components located within the housing. Additionally, micro-holes of a micro-hole structure may be organized to operate as a design element for the device while simultaneously providing ventilation. The micro-holes are sufficiently small to allow for passage of air through the micro-hole structure while also prohibiting entrance of water and/or other contaminants into the housing of the device.

The circuit board includes an electrical component that is aligned with the opening. The electronic device further includes a heat pipe mounted to the cover. A portion of the heat pipe extends into the opening of the cover to thermally communicate with the electrical component.
Abstract:
The present disclosure further contemplates a system and method that cools metal core printed circuit boards by circulating a liquid coolant so that it contacts the base metal of the metal core printed circuit board. In one example the present disclosure contemplates a direct liquid cooled MCPCB system that may include a liquid cavity creating component coupled to the base plate of a MCPCB allowing a liquid coolant to come into contact with the base plate of the MCPCB for cooling of the MCPCB. The direct liquid cooled MCPCB system may minimize thermal bottlenecks between the electrical components and the cooling fluid while reducing the number of components required in previous liquid cooled electronics systems.
