Hydraulic oil cooler product features and instructions for use

- Jul 01, 2019-

The hydraulic oil cooler is an environmentally friendly and specially developed durable water-cooled oil cooler. Its main feature is to use the structure of the air-conditioning heat exchanger to stack the stamped aluminum sheets together as heat transfer fins. This structure greatly increases the heat exchange area of the cooler and improves the production process.


The hydraulic oil cooler has a large heat exchange area and a small volume. Under the same heat exchange capacity, its volume is only about 60% of the finned tube swirling cooler. A large number of stamping parts are used, the product consistency is good, the production efficiency is high, and the quality is stable. The heat transfer tube of the hydraulic oil cooler directly uses the drawn copper tube, the wall thickness is uniform, and the residual stress is small.


When the hydraulic oil cooler is tested, both circulation circuits need to be exhausted to improve the efficiency and prevent the circuit from rusting; first add the cooling medium (water), then gradually add the working medium (hydraulic oil); according to the temperature of the cooled oil , adjust the amount of water entering the cooling water, so that the temperature of the oil is controlled within the specified range.


The working medium (oil) pressure of the hydraulic oil cooler should be greater than the cooling medium (water) pressure; the cooling medium is usually clean fresh water. In the cold season, the remaining oil and residual water must be drained when the cooler is deactivated to avoid cracking. In order to prevent the formation of scale, the temperature of the cooling water should be as low as possible, and the water flow should be larger; regular exhaust should be carried out, and internal inspection and cleaning should be carried out regularly.
