Introduction:
Cooling oil units are a commonly used oil cooling equipment in power systems, and are also suitable for departments such as metallurgy, chemical industry, mining, light industry, and heavy industry. Mainly used for circulating cooling in oil systems for equipment lubrication, variable speed system transformers, steam turbine oil, and coal mill oil.
Currently, domestically produced cool oilers are all of one model, and after many years of practice, these cool oilers have many drawbacks: large size, poor cooling effect, complex sealing, and difficult maintenance. Our company has developed a new type of cool oiler, which features excellent cooling performance, oil outlet temperature close to water temperature, simple structure, easy operation, and compact size.

Structural Features:
Lianyungang Huane Power Auxiliary Equipment Co., Ltd. produces a new type of cooler with a simple structure, easy maintenance and disassembly, reliable sealing (oil and water isolation structure), compact size, and high heat exchange efficiency (the oil temperature at the outlet is close to the water temperature).
High heat transfer efficiency is 2-3 times that of the plate-type cooler oil.
2. Low oil resistance: Due to the use of swirl guide vanes, oil enters in a tangential flow, which is beneficial for fluid operation:
3. Long service life, easy installation and inspection: The heat exchange tubes have minimal thermal expansion stress, thus avoiding common issues like tube swelling and leakage. As it remains a shell-and-tube design, installation and maintenance are convenient.
4. Utilize LV gas shielded welding in place of the traditional expansion joint structure to eliminate leaks.
5. The oil-water separator features a non-sealed structure, completely eliminating the intermixing of oil and water.
6. Employing a new heat exchange form, the oil and water run relatively, while utilizing the principle of lighter heat in liquids and heavier cold, thereby enhancing heat exchange efficiency. This achieves a similar oil and water outlet temperature, generally >2-3°C. Additionally, the outlet oil temperature can be controlled by adjusting the cooling water valve.
7. Due to its advanced structure, there is no need to install an exhaust valve in the water chamber; the operation of Huanneng Power's auxiliary equipment is straightforward.
8. Easy Maintenance. Thanks to its advanced structure and oil-water-free seals, cleaning is as simple as disassembling the upper and lower water compartments. Dismantling is very convenient.
Section 4: Selection of Coolant Coolers
Selecting a cooler, please provide parameters such as the cooling area.
1. By cooling tube type, divided into LY type tube type (used) and LYC type finned type
2. Divided into three types of cooling pipes according to the material of the cooling tubes: carbon steel, stainless steel tubes (TP304, TP304L, TP316, TP316L), and copper tubes (T2, HSN70-1, H63).
3. Divided into fixed tube sheet, floating head, and U-tube heat exchangers by structural form.
4. Available in sizes ranging from 0.5 to 500 square meters of heat transfer area. 5. Installation types include vertical and horizontal options.
Select the appropriate option based on the specific requirements for occasions and performance, or refer to our recommended specifications.
