Efficient Thermal Transfer Heat Exchanger for Liquid Industries, Providing High-Performance Solutions for Temperature Control and Process Optimization

Heat Exchanger

It is mainly used to complete the heat exchanger of the medium. The pressure vessel separates two or more fluids of different temperatures through the wall surface, so that the heat is transferred from the high-temperature fluid to the low-temperature fluid to achieve the purpose of heating, cooling, condensation or evaporation, thereby meeting the temperature control requirements of various industrial processes. Including heat exchangers, coolers, condensers, etc.

01 Heat Exchanger

Shell and Tube Heat Exchanger: It is composed of shell, tube bundle, tube sheet, head, baffle and other components. High temperature fluid flows in the tube, low temperature fluid flows outside the tube, and heat exchange is carried out through the tube wall. This structure has the advantages of strong structure, strong adaptability, easy manufacturing and maintenance, and is widely used.

Plate Heat Exchanger: It is composed of a series of metal plates with a certain corrugated shape stacked together, and narrow channels are formed between the plates. The cold and hot fluids flow in adjacent channels respectively, and heat exchange is carried out through the plates. Its advantages are high heat transfer efficiency, compact structure, and small footprint, but the processing capacity is relatively small, and the sealing requirements are high.

Spiral Plate Heat Exchanger: It is made of two parallel metal sheets rolled to form two spiral channels. The cold and hot fluids flow in their respective channels for heat exchange. It has the advantages of high heat transfer efficiency, not easy to scale, and can handle high viscosity fluids, but the manufacturing process is complicated and difficult to repair.

02 Cooler

Air Cooler: mainly composed of tube bundles, fans, frames, etc. Using air as a coolant, the hot fluid flows in the tube, and the heat is transferred to the air outside the tube through the tube wall and fins. The air is forcibly supplied by the ventilator. Air coolers do not require a water source and are suitable for water-scarce areas or occasions with high water requirements, such as some cooling processes in industries such as petrochemicals and power stations.

Liquid Cooler: The cooling liquid is transported to the heat exchanger by a pump. The cooling liquid flows in the tube or shell side and exchanges heat with the hot fluid outside the tube or in another channel, thereby reducing the temperature of the hot fluid. Common ones include shell and tube liquid coolers and plate liquid coolers.

Thermoelectric Cooler: Based on the Peltier effect, when direct current passes through a loop composed of two different semiconductor materials, heat absorption or heat release will occur at the node, thereby achieving cooling or heating. By reasonably designing the structure and connection method of the thermoelectric module, heat can be transferred from one object to another to achieve the purpose of cooling or heating.

Chiller: also known as Ice Water Host or freezer, is a device used to produce low-temperature chilled water, widely used in air-conditioning systems, industrial cooling and other fields.

03 Condenser

Evaporative Condenser: Evaporative condenser is a device that uses the evaporation of water to absorb heat to cool the refrigerant. It is mainly composed of cooling coils, spray systems, fans, water baffles, and water collection trays. During operation, high-temperature and high-pressure gaseous refrigerant flows into the cooling coils, and the spray system evenly sprinkles water on the surface of the coils to form a water film. The fan causes air to flow outside the coils, and part of the water in the water film evaporates, absorbing the heat of the refrigerant in the coils, causing it to cool and condense into liquid. The evaporated water vapor is carried away by the air, separated by the water baffle, and most of the water flows back to the water collection tray for recycling.

Air-cooled Condenser: Air-cooled condenser is mainly composed of fin tubes and fans. High-temperature and high-pressure gaseous refrigerant enters the fin tubes, and the fan forces air to flow through the outer surface of the fin tubes, and transfers the heat of the refrigerant to the air through the tube wall of the fin tubes, causing the refrigerant to cool and condense into liquid. After the air absorbs heat, the temperature rises and is discharged outdoors.

Electronic Gas Condenser: Electronic gas condenser is used in the electronics industry to cool high-purity electronic gas. The working principle is similar to that of ordinary condensers, but the material, sealing and cleanliness requirements are extremely high. The refrigeration cycle system is used for cooling, and the heat of the electronic gas is transferred to the cooling medium through the heat exchanger to cool, condense or liquefy it. In order to ensure the purity of the gas, special materials that do not react with the electronic gas are selected inside, and the equipment has good sealing to prevent the intrusion of external impurities.
