Tubular Oil Cooler Utility Model Patent∶ZL 2014 2 0456485.0
Please provide the Chinese content that you would like translated into American English.. Usage and Features∶
（1Purpose
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. Building upon the strengths 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 flowing 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.120-10The thermal resistance is primarily on the oil side. This equipment replaces the traditional arch baffles with swirl guide vanes. The main principle is that the cooling oil, after being pumped into the shell of the cooler, follows the guidance of the swirl guide vanes to rotate and move forward. As it rotates, the oil also washes along the circumference of the tubes. The structural parameters of the tubes are the result of optimized selection through multiple comparative tests, offering excellent performance and reliability for safe use. It is an ideal auxiliary equipment for steam turbine units.
（3Product Features
Tubular oil coolers offer the following advantages compared to other types of coolers:∶
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 vanes, with oil entering in a tangential flow, which is beneficial for fluid operation.
4.Long lifespan, easy installation and maintenance∶The heat exchange tubes have minimal thermal expansion stress, thus avoiding common issues like cracking and leakage. Additionally, their shell-and-tube 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 a range of cold oil cooler ordering and selection schemes. As shown in the table. For special usage requirements, please contact our company. V. Installation of the cold oil cooler∶
1Preparation before installation
Chilled oil cooler prior to shipment0.6mpaHydrostatic 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.∶“Cold ink side should be working pressure1.5Multiple water pressure tests, maintain5No leakage for minutes.
2Coolant Cooler 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.
