Hello, I'm making a caloric vestibular testing device for my senior design project where I am using a Peltier unit for cooling. I have to cool one of the sides to 24 degrees Celsius and is unable to do so. When performing the test in real life, it is found that the unit heats up and is unable to reach 24 degrees so I have used a heatsink in the simulation and the temperature values don't make sense. I have performed calculations for free convection and inputted the following values in Solidworks. Please help I am so confused!
