Tubular Cool Oil Heater Utility Model Patent∶ZL 2014 2 0456485.0
One. Application 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 advantages of similar products, our company has conducted extensive experiments on the vibration of 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] times that of the inside tube side.120-10The thermal resistance is mainly on the oil side. This equipment replaces the traditional bow-shaped baffle with a swirl guide plate. The main principle is that the cooling oil, after being pumped into the shell of the cooler, follows the guidance of the swirl guide plate and rotates forward. As it rotates, the oil also cleans along the circumferential direction of the tubes. The structural parameters of the tubes are the result of optimized selection through multiple comparative tests, demonstrating excellent performance and safety, making it an ideal auxiliary equipment for steam turbine units.
（3Product Features
The tubular oil cooler has the following advantages compared to other types of coolers:∶
1. High thermal efficiency is a feature of the plate-type cooler.2-3Multiple
2.Tightly structured∶Its compactness is equivalent to plate heat exchangers.1-2Multiple;
3.Low oil resistance due to the use of swirl guide plates, with the oil entering in a tangential flow, which is favorable for fluid operation.
4.Long service life, easy installation and maintenance∶The heat exchanger tubes have minimal thermal expansion stress, thus eliminating the common issue of tube swelling and leakage. Furthermore, the tube-shell structure facilitates easy installation and maintenance.

3Selection Guidelines
Turbine models designed by domestic and international turbine manufacturers are diverse. Based on extensive data collection, our company has compiled various cold oil cooler ordering and selection schemes, as shown in the table. If customers have special usage requirements, please contact our company. V. Installation of the cold oil cooler∶
1Preparation before installation
Coolant exchanger before shipment0.6mpaHydrostatic test. However, prior to installation, the provisions of the "Technical Specifications for Construction and Acceptance of Electric Power Projects (Turbine Generator Set Volume)" should be followed.∶“Cool oil side should be at working pressure1.5Multiple times hydrostatic test, maintain5No leakage for minutes.
2Coolant Cooler Installation∶
（1The cooler is supported on a pre-prepared bracket 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.
