Tubular Oil Cooler Utility Model Patent∶ZL 2014 2 0456485.0
One. Usage and Features∶
（1Purpose
Turbines, fans, coal mills, 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 characteristic that 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] times that of the inside tube.120-10The thermal 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 cooling oil, after entering the cold oiler shell via the oil pump, is guided to rotate by the swirl guide baffle. As it rotates, the oil washes along the circumference of the pipes. The structural parameters of the pipes 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 oilers offer the following advantages compared to other types of cool oilers:∶
1. High thermal efficiency is a feature of the plate-type cooler.2-3Multiple
2.Tightly structured∶The compactness of the plate heat exchanger1-2Multiple;
3.Low oil resistance due to the use of swirling guide vanes, with oil entering as 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. 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. For any special usage requirements, please contact our company. V. Installation of the oil cooler∶
1Preparation before installation
Chilled oil cooler is pre-tested before shipment.0.6mpaHydrostatic testing shall be conducted. However, prior to installation, the provisions of the "Technical Code for Construction and Acceptance of Electric Power Projects" (Turbine Section) must be followed.∶“Cold ink side should be operated under working pressure1.5Multiple times water pressure test, maintained5No leakage for minutes.
2Coolant Cooler Installation∶
（1The cooler is supported on pre-prepared brackets and reliably meets 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 backwards.
