Tubular Cool Oil Heater Utility Model Patent∶ZL 2014 2 0456485.0
One. Usage and Features∶
（1Usage
Turbines, fans, coal mills, pumps, and marine power systems in industrial and mining enterprises all require oil coolers for the lubrication of large and medium-sized machinery. Building upon 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
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 side.120-10The thermal resistance is primarily on the oil side. This equipment replaces the traditional arch baffles with swirl guide vanes, with the main principle being that the cooled oil enters the shell of the cooler through an oil pump, guided by 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, demonstrating excellent performance, safety, and reliability. It is 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 heat transfer efficiency is a feature of the plate-type cooler.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 baffles, with oil entering as tangential flow, which is beneficial for fluid operation.
4.Long service life, easy installation and maintenance∶Heat exchanger tubes have minimal thermal expansion stress, thus eliminating common issues such as cracking and leakage. Their tube-shell structure allows for 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 users have special usage requirements, please contact our company. V. Installation of the oil cooler∶
1Preparation before installation
Coolant exchanger before shipment0.6mpaWater pressure test is required. However, before 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 working pressure1.5Triple water pressure test maintained5Minute leak-proof.
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 plate on the support, the cold oil cooler's oil inlet direction is clockwise. Do not install it in reverse.
