Which delivers better performance for hydraulic oil radiators: suction fans or blow fans? Many customers are confused about this question. Liansheng Coolers has received numerous inquiries on this topic. Today we will discuss which type works better for hydraulic oil radiators, suction type or blow type.
First, let’s take a look at the airflow directions of these two exhaust types.
Suction type of hydraulic oil radiator: The fan blade rotates clockwise. Air flows outward from the cooler core to carry away heat from the core. From the perspective of the fan itself, the airflow moves from the fan blade to the protective mesh guard.
On the contrary, for the blow type, the fan blade rotates counterclockwise, and air is blown toward the cooler core. From the perspective of the fan itself, the airflow travels from the protective mesh guard to the fan blade.
According to research and tests, the suction type delivers better performance for hydraulic oil radiators. It achieves higher air utilization with more concentrated airflow, resulting in faster heat dissipation.
In addition, from the perspective of hydraulic oil radiator maintenance, the suction type is easier for cooler cleaning. As we all know, air coolers are generally used in dusty environments. Over time, thick dust accumulates on the heat dissipation plates, which reduces the heat dissipation performance. Therefore, the dust on the surface needs to be removed in a timely manner.
