Product Details
I. Definition
Coolers are a type of heat exchange equipment used for cooling fluids. They typically use water or air as a coolant to dissipate heat.
Section II: Applicability Scope
Suitable for various operating conditions such as cooling, condensation, heating, evaporation, and waste heat recovery.
Section 3: Categories
Tubular cooler
Tubular coolersComposed of the outer shell and the internal cooler body. Due to varying structural designs, it is categorized into pipe threaded and flanged connections; horizontal and vertical installations; floating disk and floating head configurations; coiled tube and finned tube structures for the cooler tubes; and various structural forms such as bow-shaped baffle plates, rectangular baffle plates, double weir baffle plates, and circular baffle plates, all selected based on specific conditions.
② Principle
The heat medium of the tube bundle cooler enters through the inlet pipe on the cylinder, sequentially flows through each turn channel, and twists to the outlet pipe. The cooling medium uses a two-pass flow, where the cooling medium enters half of the cooler tubes through the inlet water port and then flows into the other half through the return water cover, entering the other side's water distribution cover and outlet pipe. During the two-pass flow process, the cold medium absorbs the excess heat released by the heat medium and discharges it through the outlet, maintaining the rated working temperature of the working medium.
2. Plate-style cooler
Plate-type coolers are a new type of heat exchange equipment with high heat transfer efficiency, compact structure, small land occupation, and easy installation. They can be conveniently combined into any flow form according to different process requirements. Therefore, they are widely used in various industrial fields such as petrochemical, chemical, metallurgy, machinery, light industry, food, power, coating, and heating. In recent years, they have been used in the cooling water and pure water systems of the microelectronics industry.Ultra-pure Water SystemIt is also widely adopted in China.
Due to the refrigerant fluid (cryogenic water) andRecirculating Cooling WaterThe working fluid does not come into direct contact; instead, the heat from the circulating cooling water is transferred to the refrigerant through heat exchange plates. At this point, the circulating cooling water, which has a higher temperature, is cooled to become a low-temperature fluid. When the fluids on both sides of the heat exchange plates are at a constant temperature,
3. Air-cooled cooler
Air-cooled oil cooler (also known as an air cooler) is a type of cooler that uses air as the cooling medium.Aluminum alloy plateWingShell and tube heat exchangers feature oil and air channels with heat transfer fins, offering a larger heat exchange area per volume and high thermal efficiency, utilizing air as the medium for heat exchange. Compared to water-cooled radiators, they are not only easier to install and maintain but also prevent oil-water mixture caused by bursting copper pipes, which can severely damage the system. Furthermore, for equipment that needs to be moved frequently (such as construction machinery), they eliminate the need for water supply, and there's no need for dismantling and reconstructing water circulation systems, making them increasingly popular eco-friendly products.
Section 4: Installation Methods
Cooling unit installation methods include:Vertical Cold Oil SeparatorAndHorizontal Cold Oil CoolerVertical coolers feature a small required installation area and easy installation. Horizontal cool oilers have characteristics such as lower pressure drop and strong resistance to water impact. Therefore, selecting the appropriate vertical or horizontal cool oiler based on different site, space height, and performance requirements can better meet the needs of generator sets and other equipment.
CoolerPressure TestUpon qualification, the equipment may be put into use, and the front section should be fully drained of internal water.
(2) Check if all drain and vent valves operate smoothly and are in the correct on/off positions, and ensure that all pressure gauges and thermometers are properly installed.
(3) Inspect the foundation and supports for stability, and ensure all bolts are fully engaged and tightened.
(4) When in use, first introduce cold flow, followed by hot flow.
(5) When using cold or hot media, ensure the auxiliary line is clear first, then slowly open the outlet valve. After confirming there are no issues, open the inlet valve slowly to prevent pressure build-up. Pay attention to observing equipment changes during the operation. After the cooler is in use, leakage may occur as the temperature and pressure change, so it should be checked promptly.
