Rack-type Cool Oil Cooler Utility Model Patent∶ZL 2014 2 0456485.0
Please provide the Chinese content to be translated.. Application and Features∶
（1Usage
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 heat exchange tubes, successfully developing a new type of tubular oil cooler.
（2Product Structure and Working Principle
The tubular oil cooler operates with the characteristic that oil flows 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 here] times that of the heat transfer coefficient inside the tube.120-10The thermal resistance is primarily on the oil side. This equipment replaces the traditional bow-shaped baffle with a swirl guide baffle, with the main principle being that the cooling oil, after being pumped into the shell of the cooler, 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 result of optimal selection through multiple comparative tests, offering excellent performance and safety for use, making it an ideal auxiliary equipment for steam turbine units.
（3Product Features
Pipe-type oil coolers have the following advantages compared to other types of oil coolers:∶
1. High thermal efficiency is a feature of the plate-type cooler oil.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 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. Additionally, 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 exchanger is pre-assembled before shipment.0.6mpaHydrostatic test. However, prior to installation, the provisions of the "Technical Code for Construction and Acceptance of Electric Power Projects" (Turbine Section) should be followed.∶“Cold ink side should be at working pressure1.5Double the hydrostatic test pressure, maintained.5No 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, the cold oil cooler's oil inlet direction is clockwise. Do not install it in reverse.
