Compact tube heat exchangers are heat exchangers built within a shell but utilising compact fin technology on the outer surface of the tube. Using fins optimises the design where the shell side fluid flow and heat transfer properties would not usually be able to generate a high heat transfer coefficient. It is particularly relevant when cooling a high-pressure gas stream using a liquid as the coolant.
Nov 03, 2018 · This is called a single pass heat exchanger . In U-tube heat exchangers, fluid enters one end of the tubes and flows to the other end. However, instead of exiting, the tubes bend back in the shape of a U. Fluid flows around the bend and back to the first end, then exits the heat exchanger. This is called a double pass heat exchanger Section 5.4 Shell and Tube Heat Exchanger CorrectedA miniature shell-and-tube heat exchanger is designed to cool engine oil in an engine with the engine coolant (50% ethylene glycol). The engine oil at a flow rate of 0.23 kg/s enters the exchanger at 120°C and leaves at 115°C. The 50% ethylene glycol at a rate of
The shell and tube heat exchanger shown in the diagram above is a 'single-pass' heat exchanger. Here the tube-side fluid makes one pass through the exchanger from one end to the other. Many tubes and shell exchangers, however, have the tube-side fluid travelling back and forth through the exchanger on its way from the inlet to the outlet. Single, double or triple pass cooling - what's the Every shell and tube heat exchanger carries a flow of cooling water through its central tube core. But depending on its design, the water may flow through the unit once, twice or three times, which is done to get the optimum cooling performance for the available volume of cooling water.
