Structural form
Oil cooler according to the installation form, divided into vertical and horizontal two; According to the form of cooling tube, it is divided into two kinds: optical tube type and enhanced heat transfer tube type. According to the cooling pipe material is divided into copper pipe and stainless steel two. It should be correctly selected according to different occasions and performance requirements.

The working principle of tubular oil cooler
Water enters the tube from the water chamber, and oil enters the shell and flows outside the tube bundle. The turbine oil flowing outside the pipe and the circulating water flowing inside the pipe exchange heat through the copper pipe wall, so as to achieve the purpose of cooling the turbine oil with water.

Product characteristics
1, the heat exchange tube can use 0.5-0.8mm thin-wall stainless steel pipe, improve the overall heat transfer performance, under the same heat exchange area, the overall heat transfer coefficient is 2.121-8.408% higher than that of copper tube.
2, the pipe can use copper pipe SHn70-1 or TP304, TP316, TP316L and other high-quality stainless alloy steel, so that it has a high hardness, the steel of the pipe is also significantly improved, therefore, has a strong high-temperature steam impact resistance and vibration resistance.
3, the use of high-quality stainless steel pipe due to the smooth inner wall of the pipe, so that the bottom thickness of the boundary laminar flow thinning, not only strengthen the heat transfer, but also improve the anti-scaling performance.
4. In order to eliminate welding stress, all stainless steel pipes are heat treated at a high temperature of 1050℃ in the protective gas.
5, all stainless steel pipes are using pressure difference for leak inspection, pressure test to 10MPa, 5 minutes without pressure drop.
6, the use of high-quality stainless steel pipe after the chloride ion resistance is strong, low equipment cost.
