I. Definition
Coolers are a type of heat exchange equipment used for cooling fluids. They typically use water or air as cooling agents to dissipate heat.
Scope of Application
Suitable for various conditions such as coolers, condensation, heating, evaporation, and waste heat recovery.
Section 3: Categories
Tube and Shell Cooler
Tubular coolerComposed of the external shell and the internal cooler body. Due to varying structural configurations, it is classified into pipe threaded and flanged connection types externally; into horizontal and vertical installation forms; into floating disc and floating head floating forms; into helical and finned tube cooler tube structures; and into various structural forms such as arch 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 header on the cylinder, sequentially flows through each bend passage, and twists to the header outlet. The cooler medium utilizes a two-pass flow, where the cooler medium enters through the inlet, passes through half of the cooler tubes via the water distribution cover, and then flows into the other half of the cooler tubes through the return water cover to another side water distribution cover and outlet. During the two-pass flow of the cold medium, it 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 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 applied 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 (chilled water) andRecirculating Cooling WaterThe working fluid does not come into direct contact; instead, the heat from the circulating cooling water is transferred to the chilled water through heat exchange plates. At this point, the circulating cooling water, which is at a higher temperature, is cooled down 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 exchanger, featuring oil and air channels with heat transfer fins in the core, offering a larger heat exchange area per volume with high thermal efficiency, and using air as the medium for heat exchange. Compared to water-cooled radiators, it not only has simple installation and maintenance but also prevents the mixing of oil and water caused by bursting copper pipes, which could severely damage the system. Additionally, for equipment that requires relocation (such as construction machinery), it eliminates the need to consider water supply, and there's no need for disassembly and reconstruction of the water circulation system, making it an increasingly popular environmentally friendly product.
Four: Installation Method
Cooling unit installation methods are categorized as:Vertical Cold Oil CoolerAndHorizontal Cold Oil CoolerThe vertical cooler features a small required installation area and ease of installation. The horizontal cooler boasts lower pressure drop and strong resistance to water impact. Therefore, selecting the appropriate vertical or horizontal cooler based on the specific site, space height, and performance requirements can better meet the needs of power generation sets and other equipment.
CoolerPressure TestUpon qualification, use and start with the front 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 and securely tightened.
(4) When in use, first introduce cold flow, then hot flow.
(5) When using cold or hot media, ensure the auxiliary line is clear first, then gradually open the outlet valve. After confirming there are no issues, open the inlet valve slowly to prevent pressure build-up. Monitor the equipment for any changes during the startup process. After the cooler is in use, leaks may occur due to changes in temperature and pressure, so timely inspections should be conducted.
