Thermal Length in Plate Heat Exchangers: Pressing Depth vs. Plate Dimension•Thermal lengthis a dimensionless number that allows the design engineer to relate the performance characteristics of a channel geometry to those of a duty requirement.•Thermal length (Θ) is the relationship between temperature differenceDTon one fluid side and LMTD.•The thermal length of a channel describes the ability of the channel to affect a temperature change based o...
Hofmann plate heat exchangerAt present, plate heat exchangers have been applied in small refrigeration equipment (cooling water), and their application will be further expanded to other areas. It is mainly due to the fact that plate heat exchangers having excellent heat transfer performance, small in size, light weight, and continuously improved safety of plate heat exchangers. Overall, even though the actual application effect is good, there are...
