Construction of the first refrigerant to coolant heat exchanger
Page 1: Introduction

In a phase-change system you need an evaporator where the refrigerant boils and extracts heat from the evaporator environment (if this is Chinese to you, please visit the Phase-Change basics article first). For my cooling system I needed a way to transfer the cold to a liquid coolant which is then pumped around the system. This makes it easier to cool all required parts since it is easier to feed cold liquid through a standard waterjacket than to build multiple evaporators.

The following pages describe the construction of the heat exchanger used to transfer the cold generated by the boiling refrigerant to the coolant.
