Emmegi 2030K - 24VDC Oil Cooler

EMMEGI air-oil heat exchangers are used for cooling oil hydraulic systems using as the coolant ambient air that passes over the radiant by means of a fan operated by an electric or hydraulic motor. The cooler element, in high resistance aluminium alloy, is obtained by means of a braze-welding process carried out under vacuum. The particular configuration of the cooling pipes increases the turbulence of the fluid consequently of the exchange capacity; moreover, the presence of special jets on the cooler finning further improves the total transmission coefficient. The result is a very small, light and robust technologically advanced product.

Example of How to Choose A Heat Exchanger

Proceed with sizing the exchanger, with a knowledge of the data as the example below shows: Power to dissipate : 9 [KW] ISO VG 32 oil flow : 90 [Ipm] Oil input temperature : 60 [°c] Ambient temperature : 30 [°c] Fan operating with an electric motor 230/400V-50Hz. You can then calculate the specific heat exchange power KW/°C if you know the power to dissipate and the T (the difference between the oil input temperature and the ambient temperature)

		9KW
P=		60°-30°		=	0.30KW/°C

 

Note the oil flow (90 Ipm) and specific exchange power (0.30 KW/°C), product research is made by referring to the graph in the catalogue which is relevant to each model.
