Question 1

If I have an application that takes 50A DC continuous, then the wire that I have to use 3 or 4 AWG wire. But on a PCB it is enough to use a 1 oz / sqft 70 mm width trace/polygon plane (KiCad trace ...

Question 2

I'm moving up to 15 amperes through the following P-MOSFET: http://www.apm-mos.com/uploadfiles/2023/10/AP90P03D%20-90A%20-30V%20%20TO-252-3L.pdf At 5 volts, this means a 1.8 watt loss on the MOSFET ...

Question 3

Fan cooling is very common in electronics these days. The effects of ambient temp and air flow are well known. What about humidity? Wet air will cool better than dry air. How important is this at ...

Question 4

100% of PC cooling fans have super thin curved blades while wings and propellers in planes have more sophisticated thick airfoil shape. Is this becose of the fan blade weight limit or some other ...

Question 5

I am working on designing a small medical cabinet That needs to be cooled. The cabinet volume is about .05 cubic meters. The inside needs to be cooled to about 38 degrees F. Does anyone know how to ...

Question 6

I know there is nothing to worry about if the operating temperature of a mosfet is under 100 degree C and manufacturers usually don't bother to install a heatsink if the mosfet is operating under this ...

Question 7

I have the following setup: 2 TEC1-12706 stacked with hot side up and cold side down. I cool the hot side with a big heatsink and the cold side with water cooling. All system is clamped with 6 screws ...

Question 8

I have a USB hub that is going into an additional enclosure that is fairly airtight. This USB hub is only rated for 0C to 40C operational, however it will need to survive hotter and colder ...

Question 9

I'm not sure what will happen in this kind of scenario I'll share the photo of two diodes and basic connections below. These two diodes tab points are actually connecting same node because of tab is ...

Question 10

The two operating hot side temperatures in the Peltier module data sheets are 27° and 50°. When connecting the thermoelectric cooler, how do I get the device to operate at a specific hot side ...

Question 11

I've bought a TEC-12706 and used a 12V battery. I attached heatsinks and fans on both sides. The two sides get very hot as soon as I apply electricity to it.

Question 12

I am building a temperature controller. The controller is built in a metal rack mount chassis. The components inside the controller generally consist of ACDC power supplies, an arduino and small ...

Question 13

Could the same principle of LEDs be applied to chip (silicon or gallium) design to shift the infra-red heat towards the blue range then direct it away fromt the chip with fiber to allow the chip to ...

Question 14

I design a sync - buck converter, and I need to cool down my top side and bottom side MOSFETs. For mechanical reasons, it is easier for me to place a heat sink on top of plastic housing of MOSFETs (...

Question 15

After doing a fair amount of research I figure I should ask knowledgable people on this topic. I do know that sadly Peltiers are not that efficient. The problem at hand, I have a off grid solar ...
