Product Details
I. Definition
Coolers are a type of heat exchange equipment used for cooling fluids. They typically use water or air as the cooling medium to dissipate heat.
II. Applicability Scope
Suited for various processes such as cooler, condensation, heating, evaporation, and waste heat recovery.
III. Categories
Tubular cooler
Shell and Tube CoolersComposed of the outer shell and the internal cooler body. Due to different structural methods, it is divided into threaded pipe connection and flange connection externally; into horizontal and vertical installation forms; into floating disc and floating head floating forms; into helical tube 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 according to 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 cooling medium, however, uses a two-pass flow, where the cooling medium enters half of the cooler tubes via the water distribution cover, then flows back through the return water cover into the other half of the cooler tubes, entering the other side water distribution cover and outlet pipe. During the two-pass flow, 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-type cooler
Plate-type coolers are a new type of heat exchange equipment with high heat transfer efficiency, compact structure, small footprint, 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 petroleum, chemical, metallurgy, machinery, light industry, food, electricity, coating, and heating. In recent years, they have also been used in the cooling water and pure water systems of the microelectronics industry.Ultra-pure Water SystemAlso widely adopted in China.
Due to the refrigerant fluid (cryogenic water) andRecirculating Cooling WaterThe working fluid does not come into direct contact. They transfer heat from the recirculating cooling water to the chilled water through heat exchange plates. At this point, the recirculating cooling water, which is at 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 its cooling medium.Aluminum alloy plateWingShell and tube heat exchanger, featuring oil and air channels with heat exchange fins in the core body, offering a larger heat exchange area per volume and high thermal efficiency, and conducting heat exchange through air as the medium. Compared to water-cooled radiators, it not only simplifies installation and maintenance but also prevents the mixing of oil and water caused by bursting copper pipes, which can cause severe damage to the system. Moreover, for equipment that needs to change work locations (such as construction machinery), it does not require water supply considerations, eliminating the need for disassembly and reconstruction of the water circulation system, making it an increasingly popular eco-friendly product.
Four: Installation Method
Cooling unit installation methods include:Vertical Cold Oil CoolerAndHorizontal Cool Oil CoolerThe vertical cooler features a small required installation area and easy installation. The horizontal cooler has the advantages of lower pressure drop and strong resistance to water impact. Therefore, selecting the vertical or horizontal cooler according to different site requirements, space height, and performance needs can better meet the requirements of power generators and other equipment.
CoolerPressure TestUpon qualification, the equipment can be put into use, and the front tank should be fully filled with internal water.
(2) Check if all drain cocks and vent valves are operable and the switch positions are correct, and ensure that all pressure gauges and thermometers are properly installed.
(3) Inspect the base and support for stability, and ensure all bolts are fully and securely fastened.
(4) When in use, first introduce cold flow, followed by hot flow.
(5) When using cold or hot media, first ensure the auxiliary line is clear, then gradually open the outlet valve, check for any issues, and then open the inlet valve, making sure to open it slowly to prevent pressure build-up. Pay attention to observing changes in the equipment during the operation. After the cooler is put into use, leakage may occur due to changes in temperature and pressure, and it should be checked promptly.
