Pipe-type Cool 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 rely on 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 of heat exchange tubes, successfully developing a new type of tubular oil cooler.
（2Product Structure and Working Principle
The tube-type oil 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 that of the inside tube side heat transfer coefficient.120-10The thermal resistance is mainly on the oil side. This equipment replaces the traditional arch baffles with swirl guides, with the main principle being that the cooling oil, after entering the cold oil cooler shell through the oil pump, is directed to rotate forward by the swirl guides. As it rotates, the oil washes along the circumference of the tubes. The structural parameters of the tubes are the optimized results from multiple comparative tests, offering excellent performance, safety, and reliability, 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.2-3Not applicable.
2.Tightly structured∶Its compactness is similar 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 exchanger tubes have minimal thermal expansion stress, thus eliminating common issues like cracking and leakage. Moreover, due to their tube-and-shell structure, installation and maintenance are convenient.

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.0.6mpaHydrostatic testing is required. However, prior to installation, the provisions of the "Technical Specifications for Construction and Acceptance of Electric Power Projects (Turbine Generator Part)" should be followed.∶“Cold ink side should be worked at pressure1.5Triple water pressure test maintained5No leakage for minutes.
2Coolant Separator Installation∶
（1The cooler is supported on pre-prepared brackets 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.
