Pipe Type Cool Oil Heater Utility Model Patent∶ZL 2014 2 0456485.0
One. 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. Based on the advantages of similar products, our company has conducted extensive experiments on the vibration of 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 cooler 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 that of the inside tube side 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 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 cleans along the circumferential direction of the pipes. The structural parameters of the pipes are the result of optimal selection through multiple comparative tests, demonstrating excellent performance and safety. It is an ideal auxiliary equipment for steam turbine units.
（3Product Features
The tubular oil cooler has the following advantages compared to other types of coolers:∶
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 swirl guide vanes, with oil entering in a tangential flow, which is favorable 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. 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 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
Pre-factory testing for cold oil cooler0.6mpaHydrostatic test required. However, prior to installation, the provisions of the "Technical Specifications for Construction and Acceptance of Electric Power Projects (Turbine Generator Set Chapter)" should be followed.∶“Cooling oil side should be operated at working pressure1.5Double the hydrostatic test pressure, maintain5Zero 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 arch baffles to swirl baffles on the support, the cold oil cooler's oil inlet should be installed in the clockwise direction; do not reverse.
