Hi there, I am currently working on a product which aims to aid in sports recovery. The product is a wrap which goes around a part of the leg and the user can select a hot or cold recovery session.
To achieve the hot and cold effect I am using a peltier module aka a TEC(thermoelectric cooler) and reversing the polarity determined by what setting the user chooses (hot or cold). When the heat setting is selected the peltier will rise to 50 degrees (celsius) and when the cold setting is selected the peltier should be at around 5 degrees.
I have been testing the TEC with an adjustable power supply and I cannot get the peltier device to drop to anything below 20 degrees. Any advice on how to to reduce this to the desired 5 degrees?
Thanks for any replies
