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 agent to dissipate heat.
Section II: Application Scope
Suitable for various operating conditions such as coolers, condensation, heating, evaporation, and waste heat recovery.
Section 3: Categories
Tubular cooler
Tube-in-tube coolerComposed of the external shell and the internal cooler body. Due to varying structural designs, it is categorized into pipe thread and flange connections externally; into horizontal and vertical installations; into floating disc and floating head types; into helical tube and finned tube structures for the cooler; and into various configurations such as arch baffles, rectangular baffles, double weir baffles, and circular baffles, all selected based on specific conditions.
② Principle
The heat medium of the tube-type cooler enters through the inlet pipe on the cylinder, sequentially passes through each bend channel, and曲折ly flows to the outlet pipe. The cooler medium, however, utilizes a two-pass flow, where the medium enters half of the cooler tubes via the inlet, then flows back through the return cover into the other half of the cooler tubes, reaching the other side's water separator 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 working medium at the rated operating temperature.
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 petrochemicals, 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 widely adopted in China as well.
Due to the refrigerant fluid (cooling medium) andRe-circulated cooling waterThe working fluid does not come into direct contact. They transfer heat from the circulating cooling water to the chilled water through heat exchange plates. At this point, the circulating 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 plate are at a constant temperature for heat transfer,
3. Air-cooled cooler
Air-cooled oil cooler (also known as air cooler) is a type of cooler that uses air as its cooling source.Aluminum alloy plateWingShell-and-tube heat exchanger featuring oil and air channels with heat exchange fins, offering a larger heat exchange surface area per volume, high thermal efficiency, and heat exchange via air medium. Compared to water-cooled radiators, it not only features simple installation and maintenance but also prevents the mixing of oil and water due to bursting copper pipes, thereby avoiding severe damage to the system. Furthermore, for equipment that needs to be moved to different work locations (such as construction machinery), it eliminates the need to consider water supply, as there is no need to dismantle and reconstruct a water circulation system, making it an increasingly popular environmentally friendly product.
IV. Installation Method
Cooling unit installation methods include:Vertical Cold Oil CoolerAndHorizontal Cool 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 conditions, space heights, and performance requirements can better meet the needs of generators and other equipment.
CoolerPressure TestUpon qualification, the unit may be put into use, and the front section should be completely drained of internal water.
(2) Check if all drain cocks and vent valves are operable and in the correct on/off positions, and ensure that all pressure gauges and thermometers are properly installed.
(3) Inspect the foundation and support for stability, and ensure all bolts are fully engaged and securely tightened.
(4) When in use, first introduce cold flow, followed by hot flow.
(5) When using chilled or heated media, ensure the auxiliary line is clear first, then gradually open the outlet valve. After confirming no issues, open the inlet valve slowly to prevent pressure build-up. Pay attention to observing any changes in the equipment during the operation. After the cooler is in use, leakage may occur with changes in temperature and pressure, so it should be checked promptly.
