，全称是“风冷式油冷却器”。 The air
cooler used in the hydraulic system is called "air-cooled oil cooler". The main components are aluminum alloy radiator core, casing, and fan. Talking about the fan here, the environmental temperature used by the fan is particularly mentioned, and the temperature factors around the fan must be carefully and carefully considered. Generally speaking, there is a range requirement for the use temperature of the whole fan: -10 ℃ ~ + 60 ℃.
If your situation is special and exceeds this normal range, you must highlight it when ordering. 的散热效率是非常因难的，和其在安装时由过滤网、管道、各种组件产生的系统压力损失有原因。 It is very difficult to accurately calculate the heat dissipation efficiency of liquid air coolers
without ready-made data, and there are reasons for the system pressure loss caused by filters, pipes, and various components during installation. These losses are proportional to the square of the air volume. The best installation conditions are to ensure that the wind can be freely entered and exited. Installing other components directly at the fan inlet will cause turbulence and increase noise.
The air volume required by the cooling system can be calculated by the following formula:
Ⅴ = 3100xP / △ t
Ⅴ: Required air volume (m3 / h)
P: heat generated by the equipment (kw)
△ t: Temperature difference between inlet and outlet (℃)
的设计。 The temperature difference between the inlet
and outlet air is generally 5 ~ 15 ℃, depending on the design of the air cooler
in the liquid area.
