Product Details
I. Definition
Coolers are a type of heat exchange equipment used for cooling fluids. They typically use water or air as a coolant to dissipate heat.
II. Scope of Application
Suitable for various conditions such as coolers, condensation, heating, evaporation, and waste heat recovery.
Section 3: Categories
Tube-Type Cooler
Shell and Tube CoolerComposed of the external shell and the internal cooler body. Due to different structural methods, it is divided into threaded pipe connection and flange connection externally; into horizontal and vertical installation forms; into floating disc and floating head floating forms; into helical tube and finned tube cooler tube structures; and into various structural forms such as arch baffle plates, rectangular baffle plates, double weir baffle plates, and circular baffle plates, all selected according to specific conditions.
② Principle
The heat medium of the tube bundle cooler enters through the header on the cylinder, sequentially flows through each baffled passage, and twists to the header outlet. The cooler medium uses a two-pass flow, where the cooler medium enters half of the cooler tubes through the inlet, then flows back through the return water cover into the other half of the cooler tubes, entering the other side of the water separator and the outlet pipe. During the two-pass flow process, the cold medium absorbs the excess heat released by the heat medium and discharges it through the outlet, maintaining the rated working temperature of the working medium.
2. Plate Cooler
Plate-type coolers are a new type of heat exchange equipment with 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 industry, metallurgy, machinery, light industry, food, power, coating, and heating. In recent years, they have also been used in the 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 (cooling medium) andRe-circulating cooling waterThe working fluid does not come into direct contact; instead, it transfers heat from the circulating cooling water to the chilled water through heat exchange plates. At this point, the circulating cooling water with higher temperature cools down to become low-temperature fluid. When both fluids on either side of the heat exchange plates are at a constant temperature,
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 exchanger, featuring oil and air channels with heat exchange fins in the core body, offering a larger heat exchange area per volume with high heat transfer efficiency, and heat exchange is conducted through air. Compared to water-cooled radiators, it not only offers easy installation and maintenance but also prevents oil-water mixing caused by burst copper pipes, thus avoiding severe damage to the system. Additionally, for equipment that needs to be moved to different work locations (such as construction machinery), it does not require water supply considerations, eliminating the need for disassembly and reassembly of water circulation systems, making it an increasingly popular eco-friendly product.
Four: Installation Method
Cooling unit installation methods are categorized as:Vertical 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 height, 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 internal water.
(2) Inspect if all drain cocks and vent valves operate smoothly and are functional, as well as the positions of the switches. Check if the pressure gauge and thermometer are all properly installed.
(3) Inspect the foundation and supports for stability, and ensure all bolts are fully engaged and tightened.
(4) When in use, first introduce cold flow, then 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, making sure to open it slowly to prevent pressure build-up. Pay attention to observe any 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.
