Plate and Frame Heat Exchanger

thingiverse

These files enable users to build a basic (flat) plate and frame heat exchanger. I employ this model to illustrate how P&F heat exchangers function in my chemical engineering Heat Transfer course at Villanova University. To create your own exchanger, you will need to print: 1 x Top Plate as many middle plates as desired, but a minimum of 3 is recommended 1 x Bottom Plate The ports should tightly fit tubing with 1/4" OD and 1/8" ID. However, it's possible that using a zip tie may be necessary to prevent leaks. Speaking of leaks, I have included a template for a gasket that can be used between the plates. Various materials can be used for the gasket, but Parafilm has proven successful in my experience. You will also need 12 x 1/4" bolts with (wing) nuts to secure the plates together. Note: The material used to print these plates determines the maximum temperature of your hot stream. For instance, I use a hot stream with an inlet temperature of 104°F and ice water as a cold stream to prevent plate warping or melting. This temperature difference still allows for significant heat exchange.
