Heat sinks play an important role in circuit design, providing an efficient path for heat to be transferred into the ambient air and away from electronic devices. Without them, many electronics such as BJTs, MOSFETs, linear regulators, BGA packages, and so on are more likely to overheat, causing damage or complete component failure. To further […]
3D printed liquid cooled heatsinks cool down TO-247 transistors
https://www.electronics-lab.com/3d-printed-liquid-cooled-heatsinks-cool-down-to-247-transistors/
Standard Transistor Cooler Made by 3D-printing using SLM (Selective Laser Melting) A very effective way to dissipate the high heat flux densities of electronic power modules or power devices with high power density is the use of micro-coolers or micro-channel heat sinks made by SML. These active small cooling elements can transmit up to 1000 […]
Do You Need to Use a Fan for Cooling with the New Raspberry Pi 4?
https://www.electronics-lab.com/need-use-fan-cooling-new-raspberry-pi-4/
Alasdair Allan @ blog.hackster.io explores this question in details. Every time a new Raspberry Pi is released there are mutterings about the thermal control of the new board. But this time, it looks like it might well be necessary to add some passive, or even active, cooling to the Raspberry Pi to keep it from […]

At the Embedded World Conference 2019, imec, a world-leading research and innovation hub in nanoelectronics and digital technologies, presents a silicon-based compact microchannel heat sink that enables high heat flux dissipation. The imec heat sink assembled to a high performance chip for cooling the latter one achieves a low total thermal resistance of 0,34K/W to […]
Thermal design: Get the heat out of the electronics
https://www.electronics-lab.com/thermal-design-get-heat-electronics/
Paul Rako@ edn.com discuss about thermal design in electronics and how to design your board to dissipate it effectively. If you have high-powered LEDS, or a power supply, or are trying to control larger motors, you have to get a lot of heat out of your circuit boards. The classic way to dissipate heat is […]
