The cooling methods of the hydraulic system mainly include water-cooled, air-cooled and cooled. But how do these cooling methods are embodied? Dalan Hydraulics tells you.

1. Water cooling type includes tube type and corrugated board type
1 tube type
a. The cooling water flows through the tube, the oil flows between the tubes, the middle folding plate makes the oil flow, and the two-way or four-way flow mode is adopted to enhance the cooling effect, the heat dissipation effect is good, and the heat dissipation series can reach 350-580W. /(m2·°C).
b. There are mainly fixed folding type, floating head type, double tube type, U-shaped tube type, vertical type, horizontal type and the like.
2 corrugated plate
a. Using the plate type herringbone or oblique corrugated structure to superimpose the contact points formed by the arrangement, so that the liquid flow can form turbulent flow under the condition that the flow rate is not high, the heat dissipation effect is improved, the heat dissipation effect is good, and the heat dissipation coefficient can reach 230-815 W/(m2· °C).
b. Mainly human-word corrugated, oblique corrugated, etc.
2, wind cooling
1 Wind cooling oil, simple structure, small volume, light weight, small thermal resistance, large heat exchange area, convenient use and installation, high heat dissipation efficiency, oil heat dissipation coefficient can reach 116-175W/(m2·°C).
2 mainly indirect, fixed, floating, support, hanging and so on.
3, refrigeration
1Using the Freon refrigeration principle to absorb and discharge the heat in the hydraulic oil, the cooling effect is good, and the cooling temperature control is convenient.
2 Mechanical refrigeration type mainly has box type and cabinet type.
