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
Suited for various applications including coolers, condensers, heaters, evaporators, and waste heat recovery.
Section 3: Categories
Tubular cooler
Tubular coolerComposed of the outer shell and the internal cooler body. Due to variations in specific structural designs, they are categorized into threaded pipe connections and flanged connections externally; into horizontal and vertical installations; into floating disc and floating head types; into coiled 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 tubular cooler enters through the inlet connection on the cylinder, sequentially flows through each bend channel, and曲折ly reaches the outlet connection. The cooler medium, however, employs a double-pipe flow system, where the medium enters through the inlet, passes through half of the cooler tubes via the water distributor, then flows back through the return cover into the other half of the cooler tubes, reaching the other side water distributor and outlet pipe. During the double-pipe flow process, the cold medium absorbs the excess heat released by the heat medium and is expelled through the outlet, maintaining the working medium at the rated operating temperature.
2. Plate Cooler
Plate heat exchangers are a new type of heat exchange equipment featuring 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, thus finding extensive applications in various industries such as oil, petrochemical, metallurgy, machinery, light industry, food, power, coating, and heating. In recent years, they have been widely 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 (chilled water) andRe-circulating Cooling WaterThe working fluid does not come into direct contact. They transfer heat from the circulating cooling water to the refrigerant water through heat exchange plates. At this point, the circulating cooling water, which is at a higher temperature, cools down 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 (shortened to air cooler) is a type of cooler that uses air as the cooling medium.Aluminum alloy plateWingShell and tube heat exchangers, characterized by their oil and air channels both featuring heat exchange fins, offer a larger heat exchange area per volume, resulting in high thermal efficiency and heat exchange through air. Compared to water-cooled radiators, they are not only easy to install and maintain but also prevent the mixing of oil and water caused by bursting copper pipes, which could severely damage 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.
Section 4: Installation Method
Cooling unit installation methods include:Vertical Cold Oil SeparatorAndHorizontal Oil CoolerVertical coolers feature compact installation area and easy installation. Horizontal cool oilers have lower pressure drop and strong resistance to water impact. Therefore, selecting the appropriate vertical or horizontal cool oiler based on specific site requirements, space height, and performance needs can better meet the needs of generator sets and other equipment.
CoolerPressure TestUpon qualification, the equipment can be put into use, and ensure all internal water is drained before operation.
(2) Check if all drain cocks and vent valves are operational and the positions of the switches are correct, as well as if the pressure gauges and thermometers are fully installed.
(3) Inspect the base and support for stability, and ensure all bolts are fully and securely tightened.
(4) When in use, first introduce cold flow, followed by hot flow.
(5) When using cold or hot mediums, first ensure the auxiliary line is clear, then slowly open the outlet valve. After confirming there are no issues, open the inlet valve and do so gradually to prevent pressure build-up. Pay attention to observing equipment changes during the operation. After the cooler is in use, leakage may occur due to changes in temperature and pressure, so it should be checked promptly.
