Plate Exchanger Design

[Ultrasonic2]

IF your trying too cool the entire load of your CPU then you need enough cooling power (TEC QMAX) + losses to cool your CPU. In most cases a single TEC cannot achieve this. but to answer your question when you decrease input voltage relative to it's max voltage the TEC's COP (efficiency) INCREASES therefore two 500QMAX TEC's running at 50% of their input voltage will beable to move MORE heat while using LESS power than one 500QMAX TEC running at 100% of its input voltage.


A plate exchanger will just reduce the efficiency of your system, the only point of a plate exchanger is to transfer heat between two different fluids this maybe useful when transferring heat from oil to water or from salt water to fresh water, But of no help from PC cooling fluid to PC cooling fluid. Lastly the plate exchanger by it's self would not help you in any way to prevent your pc from going sub dew point and therefore collecting water.
