Product Description

High Efficiency C-276 Plate Heat Exchanger Plates With Gasket For Oil Cooler

GEA Heat Exchanger Plates

 Heat exchanger plate is composed of concave and convex stainless steel plates that are stamped and formed. The concave and convex lines between the two adjacent plates are combined at 180 degrees, so the concave and convex ridges between the two plates of the heat exchanger plate form a staggered contact point, and the contact points are combined by vacuum welding to form a high-pressure resistant staggered flow structure of the heat exchanger plate, and these staggered flow structures make the cold and hot fluids in the heat exchanger plate produce strong turbulence and achieve high heat exchange effect. A  heat exchanger plate consists of a set of corrugated metal plates with four corner holes for the passage of two liquids for heat transfer. The sheet metal is mounted in a frame with a fixing plate and a movable hold-down plate on the side and is clamped with clamping bolts. The plates are fitted with sealing gaskets to seal the fluid channels and guide the fluids to flow alternately into their respective flow channels to form a heat exchange. The flow rate of the fluid, its physical properties, the pressure drop and the temperature difference determine the number and size of the plates. The corrugated plate not only increases the degree of turbulence, but also forms many support points that are sufficient to withstand the pressure difference between the media. The metal plate and movable plate hold-down plate are suspended from the upper guide rod and positioned by the lower guide rod, while the rod end is fixed to the support column.

Applacations

Heat exchanger plate Choose:

• The choice of plate types and corrugation patterns for heat exchangers plate should be based on the specific heat transfer conditions and requirements. In situations where there is a large flow rate and a small allowable pressure drop, plates with low resistance should be selected. The selection of removable or brazed plate heat exchangers should be determined based on the pressure and temperature conditions of the heat transfer medium.
• For equipment with a large heat transfer area, it is not advisable to choose plates with excessively small individual plate areas. This is because having too many plates may result in low flow velocity between the plates, leading to a decrease in the overall heat transfer coefficient.

Production Process:

The production of stainless steel plates for plate heat exchangers involves several precise steps to ensure high-quality performance and longevity.

• Cutting and Leveling: Stainless steel plates are accurately cut using advanced machine tools to meet the specific design requirements. After cutting, a leveling treatment is applied to ensure a smooth and even surface. This step is crucial for maintaining efficient heat transfer capabilities.
• Stamping: The flattened plates undergo a meticulous stamping process using hydraulic presses. This process creates unique herringbone patterns on the plates, which significantly increase turbulence inside the heat exchanger. The controlled turbulence promotes optimal heat transfer by maximizing fluid contact with the plate surfaces. Special attention is given to maintaining precise control during stamping to prevent plate deformation or damage.
• Surface Treatment: To enhance corrosion resistance and optimize heat transfer performance, the plates undergo surface treatments such as polishing, sandblasting, or coating. The specific treatment method is selected based on the desired requirements and operating conditions. These treatments improve the plates' resistance to corrosion, fouling, and scaling, ensuring long-term efficiency and reliability.
