The first type of hydraulic machine cooler has a tubular type, such as double tube type, vertical type, horizontal type, and floating head type. This type of feature is that the water used for cooling flows through the inside of the pipe, and the oil flows through the interval between the tubes. The folded plate in the middle allows the oil to flow. The two-way or even four-way flow method is used. Its cooling effect is even stronger.
The second type of corrugated plate is also divided into a herringbone and a diagonal corrugated type. The contact points arranged by the corrugated structure allow the fluid to form a turbulent flow at a low flow rate, which greatly improves the heat dissipation effect.
The third type of air-cooled hydraulic coolers are divided into indirect, fixed and suspended types. It has many features, its simple structure, small size, small weight and ease of use are its advantages.
