WebbThe counter-flow heat exchanger has three significant advantages over the parallel flow design. First, the more uniform temperature difference between the two fluids minimizes the thermal stresses throughout the exchanger. Second, the outlet temperature of the cold fluid can approach the highest temperature of the hot fluid (the inlet temperature). WebbFör 1 dag sedan · Thus, heat exchangers function by allowing a fluid of higher temperature ( F1) to interact—either directly or indirectly—with a fluid of a lower temperature ( F2 ), which enables heat to transfer from F1 to F2 to move towards equilibrium. This transfer of heat results in a decrease in temperature for F1 and an increase in temperature for F2. get paid before payday australia https://lisacicala.com
