Plate heat exchangers can be used in the ventilation system of chemical workshops to cool and reduce the temperature of high-temperature exhaust, transfer heat to fresh air, and achieve energy recycling. For example, in petrochemical plants, the high-temperature gas generated by the reaction is cooled by a plate heat exchanger and then subjected to subsequent treatment, which not only improves energy utilization efficiency but also protects subsequent equipment. At the same time, for the possible corrosive gases in the chemical workshop, corrosion-resistant plate heat exchangers can be used to ensure stable equipment operation and maintain good ventilation and air quality in the workshop.
Why do hotels install plate heat exchangers？
In the guest room area, plate heat exchangers can ensure the gentle supply of fresh air, avoiding the impact of large temperature differences between the fresh air and the indoor environment on guests' rest, while maintaining fresh air and enhancing the accommodation experience. In densely populated areas such as banquet halls and conference rooms in hotels, plate heat exchangers can quickly remove polluted air and replenish fresh air that has been heated, maintaining good air quality and temperature and humidity to meet the needs of large-scale events and conferences. In addition, in the kitchen area of the hotel, plate heat exchangers combined with oil fume purification equipment not only remove oil fume but also recover heat, reduce energy consumption, and improve the working environment of the kitchen.
How to use plate heat exchangers in the ventilation system of office buildings
Plate heat exchangers are used in the ventilation system of office buildings, which can introduce fresh air that has undergone heat exchange treatment when the outdoor temperature is suitable in spring and autumn, achieving natural ventilation and reducing the frequency of air conditioning use; In winter and summer, preheat or pre cool the fresh air to reduce air conditioning load and create a comfortable office environment. Moreover, plate heat exchangers can also be combined with fresh air purification devices to filter pollutants in outdoor air, providing employees with healthy and clean air and improving work efficiency.
How to reduce energy consumption in mall air conditioning systems
Plate heat exchangers, with their efficient energy recovery mechanism, can transfer heat or cold during the exchange process between exhaust and fresh air. According to actual data statistics, after installing plate heat exchangers, the energy consumption of air conditioning systems in shopping malls can be reduced by 20% -30%, greatly reducing electricity and fuel consumption, lowering operating costs, and responding to the national call for energy conservation and emission reduction, helping to achieve the "dual carbon" goal.
Common types of heat exchangers in agricultural ventilation
Plate heat exchanger: Its advantages are compact structure, high heat transfer efficiency, small footprint, and easy disassembly, cleaning, and maintenance. A ventilation system suitable for various agricultural facilities such as greenhouses and breeding farms, which can achieve efficient sensible heat exchange.
Heat pipe heat exchanger: With the heat pipe as the core heat exchange element, it utilizes the phase change heat transfer of the working fluid inside the pipe to achieve heat transfer. Heat pipe heat exchangers have the advantages of high heat transfer efficiency, good isothermal properties, and the ability to achieve long-distance heat transfer. In the agricultural field, especially in places with strict requirements for environmental temperature and humidity control, such as animal rooms and laboratories, heat pipe heat exchangers can effectively recover waste heat while avoiding cross contamination and adapting to a wide temperature range environment.
Shell and tube heat exchanger: composed of shell, tube bundle, tube plate and other components, the fluid flows in the tube and shell sides for heat exchange. The shell and tube heat exchanger has a sturdy structure and can withstand high pressure and temperature, making it suitable for large-scale agricultural facilities that require high stability and reliability of ventilation systems, such as large greenhouse clusters or large-scale breeding farms. By installing fins on the tube, its heat transfer efficiency can be further improved and its applicability in agricultural ventilation can be enhanced.

Heat dissipation principle of wind turbine cooling system
During the operation of wind turbines, the heat generated by energy conversion and solar radiation needs to be dissipated to ensure the expected lifespan of the components inside the nacelle. We have developed a customized wind turbine cooling system for you, which effectively dissipates heat and keeps the equipment within its normal operating temperature range.
Radiators are typically in close contact with the heating components of wind turbines, transferring heat to the radiator body through molecular vibrations in the solid medium. Due to the excellent thermal conductivity of metals, they can quickly transfer heat from the heat source to the surface of the radiator to achieve cooling purposes.

Application of Plate Heat Exchanger in Industrial Ventilation Field
Plate heat exchangers are mainly used for air heat exchange in the industrial ventilation industry to achieve functions such as air preheating, cooling, or energy recovery in ventilation systems. The following are their solutions and technical principles:
Solution
Air air heat exchange: In some industrial places, such as large factories and workshops, it is necessary to preheat or cool the fresh air in the ventilation system. Plate heat exchangers can exchange heat between the discharged hot or cold air and the incoming fresh air, allowing the fresh air to reach a certain temperature before entering the room, thereby saving energy and improving the comfort of the indoor environment.
Energy recovery: For some industrial processes that generate a large amount of waste heat, such as metallurgy, chemical industry, etc., plate heat exchangers can be used to recover heat energy from exhaust gas and transfer it to fresh air or other media that need to be heated in the ventilation system. For example, high-temperature exhaust gas is heat exchanged with air in the ventilation system through a plate heat exchanger, and the air is heated and used for heating or other process in the workshop.
Technical principles
Structure and heat transfer method: Plate heat exchangers are composed of a series of metal plates with corrugated shapes, forming narrow channels between the plates. Cold and hot fluids flow in adjacent channels. When hot and cold fluids pass through a plate, heat is transferred through the plate. Due to the large surface area and good thermal conductivity of the plate, efficient heat exchange can occur between the hot and cold fluids.
