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

Suitable for various conditions such as coolers, condensation, heating, evaporation, and waste heat recovery.

Tube-in-tube cooler

Tube-in-tube coolerComposed of the outer shell and the internal cooler body. Due to varying structural designs, the external connection types are pipe threaded and flanged; the installation types are horizontal and vertical; the floating types are disc floating and head floating; the tube structures of the cooler are coil tube and finned tube; and the baffle structures include arch baffles, 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 header on the cylinder, sequentially flows through each bend passage, and twists to the header outlet. The cooling medium utilizes a two-pass flow, where the cooling medium enters half of the cooler tubes via the water distribution cover, then flows back into the other half of the cooler tubes through the return water cover, to another side water distribution cover 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 featuring high heat transfer efficiency, compact structure, small footprint, and easy installation. They can be conveniently combined into any flow form to meet different process requirements, thus being widely used in various industrial fields such as petrochemical, chemical, metallurgy, machinery, light industry, food, power, coating, and heating. In recent years, they have been increasingly applied in the cooling water and pure water systems of the microelectronics industry.Ultra-Pure Water SystemAlso 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 through heat exchange plates. At this point, the circulating cooling water with a higher temperature is cooled down to become a low-temperature fluid. When the heat transfer is isothermal on both sides of the heat exchange plate,

3. Air-cooled cooler

Air-cooled oil cooler (also known as an air cooler) is a cooling device that uses air as its cooling medium.Aluminum alloy plateWingShell and tube heat exchangers featuring oil and air channels with heat transfer fins, offering a larger heat exchange surface area per volume 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 oil-water mixing caused by burst copper pipes, which could severely damage the system. Moreover, for equipment that requires relocation (such as construction machinery), they eliminate the need for water supply considerations, as well as the dismantling and reconstruction of water circulation systems, making them increasingly popular eco-friendly products.

IV. Installation Method

 Cooling units are available in various installation methods.Vertical Cold Oil CoolerAndHorizontal Cold Oil CoolerThe vertical cooler features a small required installation area and easy installation. The horizontal cooler boasts lower pressure drop and strong resistance to water impact. Therefore, selecting the appropriate vertical or horizontal cooler based on specific site conditions, space height, and performance requirements can better meet the needs of generators and other equipment.

ChillerPressure TestUpon qualification, the equipment may be put into use, ensuring the front section is fully drained of internal water.

(2) Inspect the operation of all drain and vent valves, ensuring they are smooth and functional as well as the correct positioning of switches. Verify that all pressure gauges and thermometers are properly installed.

(3) Inspect the base and support for stability, and ensure that 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, 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 do so gradually to prevent pressure build-up. Pay attention to observing any changes in the equipment during the operation. After the cooler is in use, leakage may occur as the temperature and pressure change, so it should be checked promptly.
