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: Applicability Range
Suitable for various processes such as cooler, condensation, heating, evaporation, and waste heat recovery.
Section 3: Categories
Shell and Tube Cooler
Shell and 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 structures 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 header on the cylinder, sequentially passing through each bend passage, and曲折ly flows to the header outlet. The cooler medium utilizes a two-pass flow, where the cooler 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, entering the other side of the water-distributing cover and the outlet pipe. 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 working medium at the rated operating temperature.
2. Plate-style Cooler
Plate-type coolers are a new type of heat exchange equipment featuring 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 petroleum, chemical, metallurgy, machinery, light industry, food, electricity, 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 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 circulating cooling water to the chilled water 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 for heat transfer,
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 exchangers, featuring oil and air channels with heat transfer fins in the core body, offer a larger heat exchange area per volume, high thermal efficiency, and heat exchange via air. Compared to water-cooled radiators, they are not only easier to install and maintain but also prevent oil-water mixing caused by burst copper pipes, thereby avoiding severe damage to the system. Furthermore, for equipment that requires relocation (such as construction machinery), they eliminate the need to consider water supply, and there's no need for disassembly and reconstruction of a water circulation system, making them increasingly popular eco-friendly products.
IV. Installation Method
Cooler installation methods include:Vertical Cold Oil CoolerAndHorizontal 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 specific site conditions, space height, and performance requirements can better meet the needs of generators and other equipment.
CoolerPressure TestUpon qualification, the equipment can be put into use, and before starting, ensure all internal water is drained.
(2) Check if all drain cocks and vent valves are functioning smoothly and if the switch positions are correct. Ensure that the pressure gauge and thermometer are fully installed.
(3) Inspect the foundation and supports 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 cold or hot mediums, ensure the auxiliary line is clear first, then slowly open the outlet valve. After confirming there are no issues, open the inlet valve, and make sure to open it slowly to prevent pressure build-up. Pay attention to observing any changes in the equipment during the operation. After the cooler is put into use, leakage may occur due to changes in temperature and pressure, so it should be checked promptly.
