Radiator-type Cool Oil Separator 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 in 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 [insert coefficient value here] times that of the inside tube heat transfer coefficient.120-10The thermal resistance is primarily on the oil side. This equipment replaces the traditional bow-shaped baffle with a swirl guide baffle. The main principle is that the cooling oil, after being pumped into the shell of the cooler, is guided by the swirl guide baffle to rotate and move forward. As it rotates, the oil also washes along the circumferential direction of the tube. The structural parameters of the tube are the optimized results from multiple comparative tests, offering excellent performance, safety, and reliability. It is an ideal auxiliary equipment for steam turbine units.
（3Product Features
Tubular cool oil exchangers have 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.Tightly structured∶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 exchange tubes have minimal thermal expansion stress, thus avoiding common issues like cracking and leakage. Moreover, the 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 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 cooler is pre-tested before shipment.0.6mpaWater pressure test. However, prior to installation, the provisions of the "Technical Code for Construction and Acceptance of Electric Power Projects (Turbine Generator Set Volume)" should be followed.∶“Cold ink side should be working pressure1.5Double the hydrostatic test pressure retention5No leakage for minutes.
2Coolant Chiller 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 for the support, the cold oil cooler's oil inlet direction is clockwise. Do not install it in reverse.
