Description

In Astronomy and other large-scale physics experiments it is often required to create and maintain very low temperatures within a controlled environment. This means that various types of heat exchangers are used, one of which is evaporative coolers, where cooling is achieved via phase change of the coolant. The project aimed to produce a set of additively manufactured (AM) evaporative coolers for cryogenic service (down to 77 K) and compare them to a conventionally manufactured example. In this project we explored Additive Manufacturing as means of simplifying the production of heat exchangers while increasing their cooling performance.
