Pipe Type Cool Oil Cooler Utility Model Patent∶ZL 2014 2 0456485.0
One. Application and Features∶
（1Purpose
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. Based on 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 cool oil exchanger operates with the oil flowing through the shell side and water through the tube side. The heat transfer coefficient on the oil side outside the tube is [insert specific coefficient here] times that of the inside tube side.120-10The thermal resistance is primarily on the oil side. This equipment replaces the traditional arch baffles with swirl guides, with the main principle being that the cooled oil, after entering the cold oil cooler housing through the oil pump, is guided to rotate by the swirl guides. As it rotates, the oil washes along the circumference of the pipes. The structural parameters of the pipes are the result of optimized selection through multiple comparative tests, offering excellent performance and safety, making it an ideal auxiliary equipment for steam turbine units.
（3Product Features
Pipe-type oil coolers have the following advantages compared to other types of coolers:∶
1. High heat transfer efficiency is a feature of the plate-type oil 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 swirl baffles, 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, the tube-shell structure facilitates 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 ordering and selection schemes for 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 is pre-tested before shipment.0.6mpaWater pressure testing is required. However, before installation, the provisions of the "Technical Specifications for Construction and Acceptance of Electric Power Projects (Turbine Generator Set Part)" should be followed.∶“Cooling oil side should be at working pressure1.5Triple water pressure test, maintain5No leakage in minutes.
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, the cold oil cooler's oil inlet direction is clockwise. Do not install it in reverse.
