Tube-Type Cool Oil Unit 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 mechanical equipment. Based on the strengths 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 arch baffles with swirl guides, with the main principle being that the cooled oil enters the shell of the cooler through the oil pump, guided by the swirl guides to rotate and move forward. As the oil rotates, it also washes along the circumferential direction of the pipes. The structural parameters of the pipes are the result of optimized selection through multiple comparative tests, offering excellent performance, safety, and reliability. It is an ideal auxiliary equipment for steam turbine units.
（3Product Features
Tubular oil coolers have the following advantages compared to other types of coolers:∶
1. High thermal efficiency is a feature of the plate-type cooler.2-3Multiple
2.Compact structure∶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 exchanger tubes have minimal thermal expansion stress, thus common issues like cracking and leakage are not present. Moreover, their shell-and-tube structure makes installation and maintenance convenient.

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 cold oil cooler ordering and selection plans, as shown in the table. Please contact our company if you have special usage requirements. V. Installation of the Cold Oil Cooler∶
1Preparation before installation
Coolant cooler is pre-tested before shipment.0.6mpaHydrostatic 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 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 arch-shaped baffle to a swirl guide, the cold oil cooler's oil inlet direction is clockwise. Do not install it in reverse.
