Brazed Exchanger Plates
MIT Brazed Plate Exchangers can be designed with different types of channel plates suitable for various heat transfer needs. The 3 basic types of plates used in brazed exchangers are as follows.
H-Type Plate
H-Type plates have wide-angle channels. Thanks to these wide-angle channels, the fluids undergoing heat transfer move in a way that creates turbulence within the channels. Turbulence not only makes the heat transfer more efficient but also reduces the accumulation of sediment and residue, lowering the frequency and costs of maintenance. It is often chosen for the heat transfer of fluids with a high probability of leaving sediment.
L-Type Plate
L-Type plates have narrow-angle channels. These narrow-angle channels keep the pressure loss to a minimum in the fluids undergoing heat transfer. However, the turbulence in the fluid's movement decreases, which also reduces the efficiency of heat transfer. Therefore, L-Type plates are only used in heat transfer processes where pressure loss is unacceptable.
M-Type Plate
M-Type plates are a combination of L-Type and H-Type plates. These hybrid plates, containing different features of both plates, are especially preferred in situations where the temperature difference between the two fluids is very high.
