Sizing a cooling system
Liquid-cooled drive components have been selected
Gather technical data (for ΔT = 10 K)
(see below "Form: Collecting technical data")
Convert technical
data
No
Temperature increase = 10 K?
Yes
Go to "Convert tech‐
nical data"
Check requirements and ambient conditions:
●
Temperature control precision?
●
Which higher-level cooling medium can be used?
Yes
No
Increase tempera‐
ture difference?
Select cooling device:
●
Cooling capacity P ≥ ΣP
v
●
Type of cooling device?
–
Air-liquid cooling unit (P
01
= kW/K)
–
Liquid-liquid cooling unit (P
01
= kW/K)
–
Refrigerating unit (P
Refrig
= kW)
Make installation plan:
●
Components: determine interconnection (series/parallel)
●
Lines: determine lengths and diameters
Size coolant pump:
●
Fluidic data of cooling system branches
●
Parallel connection of branches
●
Series connection of branches
●
Pressure decrease in overall system
●
Working point of pump:
–
ΔH = ……… m
–
Q
p
= ……… l/min
(see below "Form: Sizing a coolant pump")
Tank volume of cool‐
ing device:
V
Tank
= ………… l
No
ΣΔp > 3000 hPa ?
Yes
