Tubular Cold Oil Cooler Utility Model Patent∶ZL 2014 2 0456485.0
Please provide the Chinese content you would like to be translated into American English.. 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 mechanical equipment. 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
The tubular cooler features a flow operation where 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 [insert specific 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 by the swirl guide plate to rotate and move forward. As it rotates, the oil also washes along the circumference of the pipes. The structural parameters of the pipes are the result of optimal selection through multiple comparative tests, offering excellent performance and safety, making it an ideal auxiliary equipment for steam 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 cooler.2-3Multiple
2.Tightly structured∶Its compactness is comparable to plate-type 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 conducive to fluid operation.
4.Long service life, easy installation and maintenance∶The heat exchange tubes have minimal thermal expansion stress, thus avoiding common issues like cracking and leakage. Additionally, their tube-shell structure facilitates 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 a selection scheme for various turbine oil coolers as shown in the table. If customers have special usage requirements, please contact our company. V. Installation of the oil cooler∶
1Preparation before installation
Coolant exchanger prior to shipment0.6mpaHydrostatic testing is required. However, prior to installation, the provisions of the "Technical Code for Construction and Acceptance of Electric Power Projects" (Turbine Generator Section) should be followed.∶“Cold ink side should be operated under working pressure1.5Triple water pressure test maintained5No leakage for minutes.
2Coolant Chiller 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, the cold oil cooler's oil inlet should be in the clockwise direction; do not install it backwards.
