cooling

Hello all, I need to run a 12V/0.6A dc fan to cool the MOSFETs of an inverter with 1kV input. it would be overkill to use some power supply to step down the 1kV to 12V or any DCtoDC converter!.. I thought of using just a resistor divider to step down the voltage to an acceptable range to use a...

Hello! I am trying to cool 6 Peltier tiles. They are 12v 5a. I have them sitting on top of aluminum cooling blocks connected to a dual fan 240 radiator. I am finding that the 240 radiator isn't coming close to cooling the hot side of the tiles enough. A large bucket of ice water works amazing...

Hi Experts, Like to know, I'm preparing a Peltier Cooler with TEC1 12706, & in same I found Cooling side started getting Hot after sometime, So is there any formula/Calculation or Circuit suggestion, which provide Constant cooling by turning ON & OFF Peltier at specific time. E.g. when I...

My goal is to rewire a Peltier AC unit by removing the on-board PSU and Analog temperature controller. I would like to convert the AC unit to Cool and Heat by reversing the Peltier modules polarity. Then control both heating and cooling functions with a PID. Then running it all with an external...
