Necessary parameters for model choosing of Hydraulic Heat Exchanger :
1. Data necessary to input For example:
Qreq [kW] Heat quantity to abstract Qreq=22kW
Voil [L/min] Oil flow Voil=100 L/min
Toil [°C] Oil Input Temp Toil=70°C
Tair [°C] Oil Output Temp Tair=30°C
2. Calculation of transforming comparative abstracted heat power into heat capability:
ETD [°C]=Toil - Tair
Difference between input temperatures of oil and cooling wind
inside the Hydraulic Air Cooled Heat Exchanger
ETD [°C]=Toil - Tair = 70°C - 30°C = 40°Cqreq[kW/°C]=Qreq / ETD
Comparative abstracted heat quantity
qreq[kW/°C]=Qreq / ETD = 22kW / 40°C = 0.55kW / °C
3. Choose a cooler according to the curve chart of abstracted quantity
According to curve chart of abstracted heat quantity ( in page18 )
Cooling capacity of DET5-4:
Q=0.61 kW/°C>qreq=0.55kW/°C=> choose DET5-4
Actual heat release:
Q=q×ETD Q=0.61KW/°C×40°C=24.4KW
4. Pressure loss
You may find out that the pressure loss is 0.81 bar according to the curve chart
5. Calculation of temperature difference between ertering oil and outflowing oil in the hydraulic Heat Exchanger
Calculating formula: △T=Q / ( Voil . ρ . Cp )
If there is no detailed parameter, you will need to recheck the
difference in the light of the formula below.△Toil[°C]=33×Q[kW]/Voil[L/min]△Toil=33×24.4kW/100 L/min=8.1°C
6.Conclusion
The Hydraulic Air Cooled Heat Exchanger model of choice: DET5-4 Actual heat abstraction quantity:
24.4kW Temperature difference between inpouring and outflowing oil through the cooler: 8.1°CPressure loss:0.81bar
