HVAC Heat Exchangers. In this video we’ll be answering what is a heat exchanger, how does a heat exchanger work and then using 3D models we’ll review real world applications to help you learn HVAC heat exchangers and building services.
We’ll look at plate heat exchangers, shell and tube heat exchangers, duct heaters, furnace evaporators, cooling coils, trench heaters, rotary heat exchangers and many many more. Watch the video from The Engineering Mindset for more info:
The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air.
Another example is the heat sink, which is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant./wikipedia
