Product Details
I. Definition
Coolers are a type of heat exchange equipment used for cooling fluids. They typically use water or air as cooling agents to dissipate heat.
Scope of Application
Suitable for various conditions such as coolers, condensers, heating, evaporation, and waste heat recovery.
Section 3: Categories
Tubular cooler
Shell and Tube CoolerComposed of the outer shell and the internal cooler body. Due to variations in structural design, it is categorized into threaded pipe connections and flange connections externally; horizontal and vertical installations; floating disk and floating head designs; coiled tube and finned tube structures for the cooler tubes; and various structures such as arch baffles, rectangular baffles, double weir baffles, and circular baffles for the baffle design, all selected based on specific conditions.
② Principle
The heat medium of the tube bundle cooler enters through the header on the cylinder, sequentially passing through each baffled channel, and曲折ly flows to the header outlet. The cooler medium utilizes a two-pass flow, where the cooler medium enters through the inlet, passes through half of the cooler tubes via a distributor cover, and then flows back into the other half of the cooler tubes through a return cover, to another distributor cover and 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 Cooler
Plate-type coolers are a new type of heat exchange equipment, featuring high heat transfer efficiency, compact structure, small land area, 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 also 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 (chilled water) andRecirculating cooling water(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 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 air cooler) is a type of cooler that uses air as its cooling source.Aluminum alloy plateWingShell-and-tube heat exchangers featuring oil and air channels with heat exchange fins, offering a larger heat exchange surface area per volume ratio and high thermal efficiency, utilizing air as the medium for heat exchange. Compared to water-cooled radiators, they are not only easy to install and maintain but also prevent the mixing of oil and water due to burst copper pipes, which can cause severe damage to the system. Moreover, for equipment that needs to be moved frequently (such as construction machinery), they eliminate the need to consider water supply, and there's no need to dismantle and reconstruct water circulation systems, making them increasingly popular eco-friendly products.
IV. Installation Method
Cooling unit installation methods include:Vertical Oil CoolerAndHorizontal Cold 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 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 the front row should be drained of internal water.
(2) Check if all drain cocks and vent valves operate smoothly and are in the correct on/off positions, and ensure that the pressure gauge and thermometer are fully installed.
(3) Inspect the base 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 slowly open the outlet valve. After checking for no issues, open the inlet valve and do so gradually to prevent pressure buildup. Observe the equipment for any changes during the startup process. After the cooler is operational, leaks may occur due to changes in temperature and pressure, so timely inspections are necessary.
