Description

Heat exchangers are a commonly used device in many different industries, with many different applications. The heat exchanger used in the brewing program here at CWU is a brazed plate and frame heat exchanger, so it cannot be taken apart for cleaning. Due to this, the overall efficiency of the heat exchanger will be reduced, causing fouling, because of the buildup of brewing material. In order to effectively combat this fouling, a heat exchanger must be constructed that can be disassembled for cleaning, and then reassembled with ease, while still being able to perform the same amount of heat transfer as the brazed system. Specifically, a gasketed plate and frame heat exchanger was constructed for this purpose, which utilizes rubber gaskets to seal the system, instead of brazing. This heat exchanger was constructed using twenty stainless steel plates, with four flow holes punched for the fluid paths, and arranged with the attached gaskets in a cross flow pattern. To test the effectiveness of this system, the heat exchanger will operate using cold tap water to cool down water heated to approximately 200 °F. The output temperature of the water will be measured, in order to see how well the heat exchanger is able to transfer heat between the two fluids. The results of this test will indicate the viability of this system, state the specific rate of heat transfer within this system, and compare this value to the previously utilized brazed heat exchanger.
