Gl Tube Type Oil Cooler Series

Short Description:

This product is manufactured by our company that combining with the int ernal and external base of advanced technology and craft. The material of h- eat-exchange pipe, adopted low-rib finned red copper pipe, used the structure of transverse current breaker board, turbulence board and the advanced manufacture craft of mechanism expanding, has the features of novel structure, small dimension, light weightand well heat-exchanging effect a- nd soon. This product is a new type and higli efficiency cooler, mainly used in low-viscosity hydraulic and oil system to cool the work oil to the specified temperature. So it is an Ideal cooling facility that can be widely used in cooling the hydraulic equipment in the trade such as chemical industry, electric power, metallurgical industry, mine and light industry and soon.

METHOD OF SELECTING COOLER

1. Calculation method

(1) Required heat transfer area A(m2)
QA=Arm -K
⑵Amount of heat：Q(Kca l/h)
Q=(H-T2)CW=(t2-tl)C，W， <2=Amount of heat(kca l/h) k=Heat transfer coefficient(kca l/m2h°C) Atiii =Mean temperature difference(°C)
Among them：D 1= inlet oil temperature °C 2=Export of oil temperature°C 。=Import water temperature°C
2=Export water temperature°C C=The specific heat of oil(kca l/kg。。 The specific heat of water(kca l/kg°C)
W=The flow of oil(kg/h) '=The flow of water(kg/h)

(3)Average temperature difference left T m(°C)

(4)Heat transfer coefficient:K(kca l/m2h°C)

a)When the cooling water flow is small and the working oil viscosity is high, K = 200 is taken；
b)Generally take K=250 when working oil；
c)When the cooling water flow is large and the working oil viscosity is low, K = 350~400 is taken0；
