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 Scope
Suited for various conditions such as coolers, condensation, heating, evaporation, and waste heat recovery.
III. Categories
Tube and Shell Cooler
Shell and Tube CoolerComposed of the external shell and internal cooler body. Due to varying structural designs, it is classified into pipe threaded and flanged connections; horizontal and vertical installation types; floating disk and floating head floating types; spiral tube and finned tube cooler tube structures; and various structures including bow-shaped baffle plates, 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 header on the cylinder, sequentially passing through each bend channel, and曲折ly flows to the outlet header. The cooler medium utilizes a two-pass flow, where the medium enters through the inlet and flows into half of the cooler tubes via the water distributor, then returns through the return water distributor into the other half of the cooler tubes, entering the other side water distributor 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 footprint, and easy installation. They can be conveniently combined into any flow form according to different process requirements, thus widely used in various industrial fields such as oil, chemical, metallurgy, machinery, light industry, food, power, coating, and heating. In recent years, they have been used in cooling water, pure water, and other applications in the microelectronics industry.Ultra-pure Water SystemIt is also widely adopted in China.
Due to the refrigerant fluid (cryogenic water) andRecirculating Cooling WaterThe working fluid does not come into direct contact; instead, it transfers 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,
3. Air-cooled cooler
Air-cooled oil cooler (abbreviated 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 in the core body, offering a larger heat exchange surface area per volume, high heat transfer efficiency, and heat exchange through air as the medium. Compared to water-cooled radiators, it not only boasts simple installation and maintenance but also prevents the mixing of oil and water due to burst copper pipes, which can cause severe damage to the system. Furthermore, for equipment that requires relocation of work sites (such as construction machinery), it eliminates the need to consider water supply, and there is no need for disassembly and reconstruction of a water circulation system, making it an increasingly popular environmentally friendly product.
Four: Installation Method
Cooler installation methods include:Vertical Cold Oil CoolerAndHorizontal Oil CoolerThe vertical cooler features a small required installation area and easy installation. The horizontal cooler has lower pressure drop and strong resistance to water impact. Therefore, selecting the appropriate vertical or horizontal cooler based on different site conditions, space heights, and performance requirements can better meet the needs of generators 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 operational and easily adjustable, and if the pressure gauge and thermometer are fully installed.
(3) Check if the foundation and supports are sturdy, and if all bolts are properly and securely tightened.
(4) When in use, first introduce cold flow, followed by hot flow.
(5) When using chilled or hot media, ensure the auxiliary line is clear first, then slowly open the outlet valve. After checking for any 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, leaks may occur due to changes in temperature and pressure, so timely inspections should be conducted.
