Liquid to Air Heat Exchanger LA5000 MFG Part Number: 387009381 The LA5000 is a recirculating liquid to air heat exchanger that offers Features ● Cooling to ambient ● High heat pumping capacity ● Compact form factor ● Long life operation Applications Cooling Particle Accelerators: Linear Accelerators and Cyclotrons● Semiconductor Fabrication Equipment Cooling ● X-ray Cooling in Industrial Scanners FLUID OPERATING POINTS Cooling Power (Qc) = 5000 Watts Thermal Conductance = 474.5 W/°CΔT (Ambient-Coolant)* = 10.5 °CΔT (Outlet-Inlet)** @ 8.3 L/min = 9.6 °C100% Water Cooling Power (Qc) = 5000 Watts Thermal Conductance = 441.5 W/°CΔT (Ambient-Coolant)* = 11.3 °CΔT (Outlet-Inlet)** @ 8.3 L/min = 10.1 °C70/30 Water-Glycol * ΔT (Ambient-Coolant) is the temperature difference between the ambient temperature and the coolant temperature that is at the outlet of the heat exchanger during steady-state operation. This temperature difference would initially be 0 and increase to the steady state value under load. This would also be the temperature at the inlet to the application.** ΔT (Outlet-Inlet) is the temperature difference between the inlet temperature and the outlet temperature of the application at the nominal coolant flow. More flow (application pressure drop less than nominal) would necessarily mean a smaller ΔT.Cooling Power (Qc) = 5000 Watts Thermal Conductance = 400.4 W/°CΔT (Ambient-Coolant)* = 12.5 °CΔT (Outlet-Inlet)** @ 8.3 L/min = 10.5 °C60/40 Water-Glycol Cooling Power (Qc) = 5000 Watts Thermal Conductance = 388.4 W/°CΔT (Ambient-Coolant)* = 12.9°CΔT (Outlet-Inlet)** @ 8.3 L/min = 11.1 °C50/50 Water-Glycol
