Tubular Cold Oil Cooler Utility Model Patent∶ZL 2014 2 0456485.0
One. Application and Features∶
（1Usage
Turbines, fans, coal mills, pumps, and marine propulsion systems in industrial and mining enterprises all require oil coolers for the lubrication of large and medium-sized machinery. Based on the advantages of similar products, our company has conducted extensive experiments on the vibration of the oil-side laminar flow in the heat exchange tubes, successfully developing a new type of tubular oil cooler.
（2Product Structure and Working Principle
The tubular oil cooler operates with the oil flowing through the shell side and water flowing through the tube side. The heat transfer coefficient on the oil side outside the tube is [insert coefficient value] times that of the heat transfer coefficient inside the tube.120-10The thermal resistance is primarily on the oil side. This equipment replaces the traditional bow-shaped baffle with a swirl guide plate. The main principle is that the cooling oil, after being pumped into the shell of the cooler, is guided to rotate by the swirl guide plate, where it washes along the tube circumference. The structural parameters of the tube are the result of optimal selection through multiple comparative tests, offering excellent performance and safety for reliable use. It is an ideal auxiliary product for steam turbine units.
（3Product Features
Tubular cool oilers have the following advantages compared to other types of cool oilers:∶
1. High thermal efficiency is a feature of the plate-type cool oiler.2-3X times
2.Tightly structured∶Its compactness is comparable to plate heat exchangers.1-2Multiple;
3.Low oil resistance due to the use of swirl baffles, with oil entering in a tangential flow, which is beneficial for fluid operation.
4.Long service life, easy installation and maintenance∶The heat exchanger tubes have minimal thermal expansion stress, thus preventing common issues like tube swelling and leakage. They are still in a tube-shell structure, making installation and maintenance convenient.

3Selection Guidelines
Turbine models designed by domestic and international turbine manufacturers are diverse. Based on extensive information collection, our company has compiled various cold oil cooler ordering and selection plans as shown in the table. If users have special requirements, please contact our company. V. Installation of Cold Oil Coolers∶
1Preparation before installation
Coolant exchanger is factory tested before shipment.0.6mpaHydrostatic test shall be conducted. However, prior to installation, the provisions of the "Technical Specifications for Construction and Acceptance of Electric Power Projects (Turbine Generator Set Part)" should be followed.∶“Cold ink side should be under working pressure1.5Twice the hydrostatic test pressure, maintained.5Minute leak-free.
2Coolant Cooler Installation∶
（1The cooler support is mounted on a pre-prepared bracket and can reliably meet its dynamic and static load requirements.
（2Due to the change from an arch-shaped baffle to a swirl guide plate for the support, the cold oil cooler's oil inlet direction is clockwise. Do not install it in reverse.
