Enginursday: Linear Regulator Thermal Tests
This Enginursday tests a 7805 regulator with various heat sinks.
It's Enginursday again!
Today I'd like to show that it's not hard to collect thermal data, and that temperatures can vary wildly depending on how the heat can (or can't) escape. I apply several types of heat-sinking materials to a TO-220 7805 and see how it responds. If you've never taken the temperature of a component before, this will be a good introduction.
Tools used:
- The FlirPiCam
- Infrared thermometer
- Thermocouple Breakout - MAX31855K
- Thermocouple Type-K
- Decade Resistance Box
- Basic multimeter
- RedBoard
- Ceramic power resistors
- Dual tracking power supply
Software used:
- Arduino sketch for data collection
- LibreOffice-- for graphs
- Tera Term
Keep on testing,
Marshall
