Consider three major aspects when choosing an air oil cooler

When using any air cooler, the first consideration is to achieve its functionality. The oil temperature requirements require its functionality to be reflected in three main aspects: applicable pressure, applicable flow, and heat transfer efficiency.


First, the applicable pressure.

The air cooler is a pressure type container. As far as the air cooler itself is concerned, the heat-resistant main body (heat exchange core) has a limited pressure resistance capability, and the physical properties, structure and processing technology of the material affect the pressure resistance of the air cooler. performance.

Second, the applicable flow.

The applicable flow rate of the air cooler is often referred to as the throughput per minute of the low viscosity liquid under static pressure. The air cooler oil passage is not susceptible to bursting in the range of a liquid flow rate of 0.2-0.4 m/s. It should be noted that under static pressure (substantially constant pressure), the hydraulic oil will pass through all the oil passages, but in the case of a pulse, the hydraulic oil will only pass through part of the oil passage, forming an instantaneous pressure that is too high to cause a change. The common cause of hot core bursting is also a matter of extra care when adjusting the machine. Therefore, it cannot be selected according to the flow rate of the air cooler equal to the displacement of the oil pump.


Third, heat exchange efficiency.

In layman's terms, it is the cooling efficiency of the air cooler. Many users choose the applicable flow when selecting the model, and then choose a wind cooler according to the model corresponding to the flow value, which is not comprehensive. Because the flow meets your requirements, it does not mean that the cooling efficiency of the air cooler also meets your requirements.

When using an air oil cooler, these three aspects must be met at the same time, in order to basically meet your requirements.
