Tubular Cool Oil Cooler Utility Model Patent∶ZL 2014 2 0456485.0
One. Application and Features∶
（1Usage
Turbines, fans, coal millers, pumps, and marine propulsion systems in industrial and mining enterprises all require oil coolers for the lubrication of large and medium-sized machinery. Building upon the strengths of similar products, our company has conducted extensive experiments on the vibration of the oil-side laminar flow in heat exchange tubes, successfully developing a new type of tubular oil cooler.
（2Product Structure and Working Principle
Tubular oil cooler operates with the feature that oil flows through the shell side and water flows through the tube side. The heat transfer coefficient on the oil side outside the tube is of [insert coefficient value here] compared to the heat transfer coefficient inside the tube.120-10The thermal resistance is primarily on the oil side. This equipment replaces the traditional arch baffles with swirl guide vanes. The main principle is that the cooled oil, after being pumped into the shell of the cold oil cooler, is guided to rotate by the swirl guide vanes. As it rotates, the oil washes along the circumference of the tubes. The structural parameters of the tubes are the result of optimal selection through multiple comparative tests, offering excellent performance and safety, making it an ideal auxiliary equipment for turbine units.
（3Product Features
The tubular cool oil exchanger has the following advantages compared to other types of cool oil exchangers:∶
1. High thermal efficiency is a feature of the plate-type cool oiler.2-3Multiple
2.Compact structure∶Its compactness is comparable to plate heat exchangers.1-2Multiple;
3.Low oil resistance due to the use of swirl guide plates, 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 eliminating common issues like cracking and leakage. Their shell-and-tube design also ensures easy installation and maintenance.

3Selection Guidelines
A wide variety of turbine types are designed by domestic and international turbine manufacturers. Based on extensive data collection, our company has compiled various cold oil cooler ordering and selection schemes, as shown in the table. If customers have special usage requirements, please contact our company. V. Installation of the cold oil cooler∶
1Preparation before installation
Chilled oil cooler is pre-assembled before shipment0.6mpaWater pressure testing is required. However, before installation, the provisions of the "Technical Specifications for Construction and Acceptance of Electric Power Projects (Turbine Generator Chapter)" should be followed.∶“Cold ink side should be subjected to working pressure1.5Multiple times water pressure test, maintain5Zero leakage for minutes.
2Coolant Separator 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 on the support, the cold oil cooler's oil inlet direction is clockwise. Do not install it in reverse.
