Plate heat exchanger sensible heat exchange stainless steel core accessories

The core component of the plate heat exchanger's sensible heat exchange stainless steel core is made of 304/316L stainless steel, with a corrugated plate structure to enhance heat transfer efficiency. It has corrosion resistance and high temperature resistance characteristics, and is suitable for multiple industries such as chemical, pharmaceutical, and food. It can flexibly customize specifications, balance efficient sensible heat exchange and convenient maintenance, and is a key component for plate heat exchanger upgrades and new construction projects.

Plate heat exchanger sensible heat exchange stainless steel core accessoriesAs the core component for heat transfer in plate heat exchangers, the material selection and structural design directly determine the heat transfer efficiency, corrosion resistance, and service life of the equipment. This accessory is made of food grade 304 or high-temperature resistant 316L stainless steel material, both of which have excellent chemical stability and can resist the erosion of acid and alkali solutions, high-temperature steam, and various industrial fluids, avoiding the heat transfer efficiency decline and equipment failure caused by the rusting and corrosion of ordinary metal cores. Among them, 316L stainless steel also added molybdenum element, further improving its resistance to intergranular corrosion and high temperature performance. It can work stably in the temperature range of -196 ℃ to 400 ℃, and is suitable for industries with strict material requirements such as chemical, pharmaceutical, and food processing.

From the perspective of structural design, the stainless steel core adopts a corrugated plate combination structure, and the special corrugated shapes (such as herringbone and oblique corrugated shapes) pressed on the surface of the plate can greatly increase the contact area between cold and hot fluids, while guiding the fluid to form a strong turbulent state inside the core. Compared to traditional skateboard cores, turbulent flow can break the thermal resistance limitation of the fluid boundary layer, making heat transfer faster and more uniform. After testing, its heat transfer coefficient can reach 1.5-2 times that of ordinary cores. Under the same operating conditions, it can significantly reduce the volume of the heat exchanger and reduce the equipment footprint. In addition, the plates are connected by precision sealing gaskets, which are made of aging resistant, high and low temperature resistant EPDM rubber or nitrile rubber materials. With the precise positioning structure of the plates, the leakage rate can be controlled at an extremely low level, meeting the strict requirements of fluid purity and hygiene safety in industries such as medicine and food.

In terms of sensible heat exchange performance, this core component exhibits efficient and stable characteristics. Sensible heat exchange mainly focuses on the heat transfer during fluid temperature changes, without involving phase transitions, which requires the core to have the ability of rapid thermal conductivity and uniform temperature control. Stainless steel material itself has good thermal conductivity, with a thermal conductivity coefficient of about 16-21W/(m · K). With the optimized flow channel design of corrugated plates, the cold and hot fluids can fully contact and quickly exchange heat inside the core. For example, in HVAC systems, using this core to recover sensible heat from air conditioning exhaust can preheat or pre cool fresh air to near indoor temperature, reducing the energy consumption of air conditioning units. According to actual application data, in air conditioning systems of large buildings such as shopping malls and office buildings, plate heat exchangers equipped with this stainless steel core can reduce air conditioning energy consumption by 25% -30%, saving a lot of electricity costs for building operations every year.

Adaptability and easy maintenance are also prominent advantages of this accessory. It adopts modular design, which can flexibly adjust the number and combination of plates according to the model, processing flow rate, and heat exchange requirements of the plate heat exchanger. From small household heat pump water heaters to large industrial heat exchange units, core specifications can be customized and adapted. During the installation process, there is no need to disassemble the entire heat exchanger. Simply open the equipment end cover to complete the replacement and assembly of the core, making the operation simple and efficient. During daily maintenance, due to the smooth surface of stainless steel material, it is not easy to scale or accumulate dirt. The surface of the plate can be quickly cleaned by high-pressure water gun flushing or chemical cleaning to restore heat exchange efficiency. The maintenance cycle is extended by more than 30% compared to ordinary cores, reducing equipment downtime for maintenance and ensuring the continuity of production and operation.

In practical applications in different industries, the value of this accessory is fully reflected. In the food processing industry, for the sterilization and cooling process of fruit juice and dairy products, the sanitary grade material of stainless steel core can avoid fluid pollution, and the turbulent design of corrugated sheet can ensure uniform heating of materials and prevent local overheating from affecting product quality; In the chemical industry, corrosion-resistant stainless steel material is used for temperature regulation of acidic and alkaline solutions, which can extend the service life of the core and reduce equipment maintenance costs; In the pharmaceutical industry, it is used for preheating and cooling of drug solutions, with strict sealing design and hygiene grade materials that comply with GMP certification standards, ensuring the safety of drug production.
