Products Infomation:

SL series spiral-flow finned column tube oil cooler is known as the latest one developed on the basis of imported prototype and advanced technology from Japan.
Main Characteristics:
A. The spiral deflector guides oil into a spiral, even and continuous flow and overcomes the traditional deflection. So it is high in heat-exchanging efficiency and low in pressure loss.
B. Small in product volume and large in heat-exchanging area, the cooling tube is made of red copper tune pressed as radiating fin.
C. Water flow covers 2-flow path and 4-flow path, and water volume includes large one (The deflector for big lead )and small one (The deflector for small lead). There are various of products to meet different demands.
Methods of selection:
A. Calculating heat quantity to exchanged Q(Kcal/h)
a. Calculating according to oil temperature requirement and flow volume
Q=Cpq(T1-T2)
In the formula: C-oil specific heat; p-oil flow volume; T1-temperature at oil inlet; T2-temperature at oil outlet.
b. Calculating according to the heat-generating quantity of hydraulic system
Q=Pr-Pc-Phc
In the formula: Pr-input power of hydraulic system; Pc-output effective power; Phc-radiating power of fuel tank and pipeline.
B. Selection of cooler type
Find out the performance curve according to the calculated heat-exchanging quantity and flow rate. The required type is located at the intersection point of the right curve.
C. Additional remarks:
In case the actual working conditions differ from those of the performance testing, such as less oil viscosity, larger water flow and bigger difference in oil & water temperature, the smaller type should be selected; whereas bigger ones.
Notes:
A. This product is suitable for fresh water only.
B. The working pressure of oil-side is 1.0Mpa and that of Water-side0.5Mpa.
C. The cooling water may be frozen in cold season, so the fresh water inside the cooler should be drawn without working.
D. Cleaning within the heat-exchanging tube(water side)must be effected for each six months.
This corporation.can manufacture all kinds of large-sized coolers with specifications according to the requirements of users.
