Pipe-Type Cool Oil Unit 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 rely on 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
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 mainly 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, while being brushed along the circumference of the pipes during rotation. The structural parameters of the pipes are the optimized results from multiple comparative tests, demonstrating excellent performance and safety, making it an ideal auxiliary equipment 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 cooler.2-3Multiple
2.Tightly structured∶Its compactness is comparable to plate heat exchangers.1-2Multiple;
3.Low oil resistance due to the use of swirling baffles, with the oil entering as a tangential flow, which is favorable for fluid operation.
4.Long service life, easy installation and maintenance∶The heat exchanger tubes have minimal thermal expansion stress, thus common issues such as cracking and leakage are not present. Installation and maintenance are convenient due to its shell-and-tube structure.

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
Coolant exchanger pre-delivery inspection0.6mpaHydrostatic test. However, prior to installation, the provisions of the "Technical Specifications for Construction and Acceptance of Electric Power Projects (Turbine Generator Set Volume)" should be followed.∶“Cold ink side should be at working pressure1.5Triple pressure test, maintain5No leakage for minutes.
2Cooling Oil Cooler Installation∶
（1The cooler is supported 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.
