产品,都有对应的性能曲线图, Each standard air cooler product has a corresponding performance curve.
The user selects the model according to the graph, which is based on two necessary parameters:
First, the actual traffic,
Second, the equivalent cooling power is also called equal ratio cooling power.
Therefore, neither of these two parameters is known, or only one of them is known, and the air cooler cannot be selected accurately.
This is risky for users. We often tell them that the core parameters are not enough to recommend the right product. Because choosing bigger or smaller can cause waste.
This is a frustrating thing.
But it is not a difficult thing.
Therefore, it is necessary for the user or manufacturer to know the two parameters of the air cooler.
There is a simple calculation formula for everyone,
According to the inlet and outlet oil temperature of the air cooler, the heat dissipation of the system is estimated,
Pv≈0.028 × L × (T in-T out)
T inlet: hydraulic oil inlet temperature (℃)
T out: Hydraulic oil outlet temperature (℃)
Pv: heat dissipation (kw)
L: Oil flow (l / min)
选型的参数。 If the above two parameters cannot be provided, only one third of the total power of the hydraulic system can be used as the parameter for the air cooler selection.
Two necessary parameters for selection and calculation of air cooler
Each standard air cooler product has a corresponding performance curve,
According to the curve chart, the user selects the model based on two necessary parameters:
First, the actual flow,
Second, the equivalent cooling power, also known as the proportional cooling power.
Therefore, neither of these two parameters, or only one of them, can accurately select the air cooler.
This is risky for users. We often tell them that the core parameters are not enough to recommend the right products. Because choosing the big one or the small one will cause waste.
This is a depressing thing.
But it's not a difficult thing.
Therefore, it is very necessary for users or manufacturers to understand the two parameters of air cooler.
There is a simple calculation formula for you,
According to the oil temperature at the inlet and outlet of the air cooler, the heat dissipation of the system is estimated,
Pv ≈ 0.028 × L × (T in-T out)
T inlet: hydraulic oil inlet temperature (℃)
T outlet: outlet temperature of hydraulic oil (℃)
Pv: heat dissipation (kw)
L: oil flow (L / min)
If the above two parameters cannot be provided, only 1/3 of the total power of the hydraulic system can be used as the parameters of air cooler selection.
