Product Details
I. Definition
Coolers are a type of heat exchange equipment used to cool fluids. They typically use water or air as the coolant to dissipate heat.
Section II: Application Scope
Suitable for various conditions such as coolers, condensation, heating, evaporation, and waste heat recovery.
Section 3: Categories
Tube-type cooler
Tubular coolerComposed of the external shell and internal cooler body. Due to varying structural designs, it is categorized into pipe thread and flange connection types externally; into horizontal and vertical installation forms; into floating disc and floating head floating types; into helical tube and finned tube cooler tube structures; and into various structures 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 inlet pipe on the cylinder, sequentially flows through each turn channel, and then曲折ly to the outlet pipe. The cooling medium, however, uses a two-pass flow, meaning the cooling medium enters half of the cooler tubes via the inlet and then flows back into the other half through the return cover, into 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-type cooler
Plate-type cooler is a new type of heat exchange equipment with high heat transfer efficiency, compact structure, small land occupation, and easy installation. It can be conveniently combined into any flow form according to different process requirements. Therefore, it is widely used in various industrial fields such as petrochemical, chemical, metallurgical, machinery, light industry, food, power, coating, and heating. In recent years, it has been used in cooling water and pure water for the microelectronics industry.Ultra-pure Water SystemIt is widely adopted in China as well.
Due to the refrigerant fluid (cryogenic water) andRecirculating Cooling Water(Working Fluid) does not come into direct contact; instead, they transfer the heat from the circulating cooling water to the refrigerant through heat exchange plates. At this point, the circulating cooling water with higher temperature becomes lower-temperature fluid as it cools down. 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 (short for 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 transfer fins in the core body, offering a larger heat exchange area per volume and high thermal efficiency, using air as the medium for heat exchange. Compared to water-cooled radiators, it not only facilitates installation and maintenance but also prevents the mixing of oil and water due to burst copper pipes, which could cause severe damage to the system. Furthermore, 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.
Section 4: Installation Method
Cooling units come in various installation methods: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 different site requirements, space heights, and performance needs can better meet the needs of generator sets and other equipment.
CoolerPressure TestUpon qualification, the equipment may be put into use, and ensure the front tank is fully filled with water.
(2) Check if all drain cocks and vent valves are operable and the switch positions are correct, and ensure that the pressure gauge and thermometer are all 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, then hot flow.
(5) When using cold or hot mediums, first ensure the auxiliary line is clear, then gradually open the outlet valve, and after checking for any issues, open the inlet valve. Be sure to open it slowly to prevent pressure buildup. Pay attention to observing changes in the equipment during the startup process. After the cooler is put into use, leakage may occur due to changes in temperature and pressure, so it should be checked promptly.
