Quanguan understands that when customers choose heat exchangers for machine tool electronic control boxes, they don’t know what type of heat exchanger to choose. We consulted a refrigeration engineer and gave everyone a common machine tool heat exchange calculation formula: Q = K * A * ΔT in...
Heat Transfer Coefficient – Formula and Calculation The heat transfer coefficientαis a calculated figure we can use to see indirect what is happening inside a heat exchanger. In an ideal world, the internal surface of a heat exchanger stays clean during its operation. If this is the case the...
The differential temperature can vary through the heat exchanger. A mean value, LTMD, is used for calculation. It is called Δtm in the general formula above. It can be calculated by the following formula, using the denominations in Figure 6.1.8. In the example with the cheese milk heater...

We present a computational method for estimating the average values of heat and mass transfer processes in a heat exchanger for use in engineering calculation methods. The formula obtained for calculating a heat exchanger is transformed to obtain a criterion dependence, which simplifies application of ...
