Tubular Cool Oil Cooler Utility Model Patent∶ZL 2014 2 0456485.0
One. Usage 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 machinery. Based on the advantages of similar products, our company has conducted extensive experiments on the vibration of the oil-side laminar flow in the 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 [insert coefficient value] times that of the inside tube side.120-10The heat resistance is mainly on the oil side. This equipment replaces the traditional bow-shaped baffle with a swirl guide baffle. The main principle is that the cooled oil, after entering the shell of the cooler through the oil pump, is guided to rotate by the swirl guide baffle. As it rotates, the oil cleanses the tube circumference. The structural parameters of the tube have been optimized through multiple comparative tests, resulting in excellent performance and safety, making it an ideal auxiliary matching product for steam turbine units.
（3Product Features
Tube-type oil cooler has the following advantages compared to other types of oil coolers:∶
1. High heat transfer efficiency is a feature of the plate-type cooler.2-3Multiple
2.Tightly structured∶Its compactness is equivalent to plate-type heat exchangers.1-2Multiple;
3.Low oil resistance due to the use of swirling baffles, with the 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, hence there is no common issue of tube expansion and leakage. Moreover, being in a tube-shell structure, they are easy to install and maintain.

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 a range of cold oil cooler ordering and selection schemes. As shown in the table. Please contact our company if you have any special usage requirements. V. Installation of the cold oil cooler∶
1Preparation before installation
Chilled oil cooler pre-delivery inspection0.6mpaHydrostatic test required. However, prior to installation, the provisions of the "Technical Code for Construction and Acceptance of Electric Power Projects (Turbine Generator Set Chapter)" should be followed.∶“Cold ink side should be operated under working pressure1.5Double the hydrostatic test pressure retention5Minute leak-free.
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 arched 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.
