heat transfer in with a hot plate - Engineering - Science

Sep 15, 2018 · Basic plate heat exchanger Plate heat exchangers use thin plates of metal to separate the two fluids. The fluids generally flow in opposite directions to improve the heat transfer. The heat of the hottest fluid is convected onto the plate wall and then conducted through to the other side.

Internal Heat Exchanger - an overview | ScienceDirect Topics

A larger heat exchanger gives more chance for the heat to transfer into the heating system water. When boilers modulate down these components stay the same size, meaning they effectively become oversized. This increases the heat exchanger's relative surface area and 'heat transfer coefficient'.
