Modular Design Plate Heat Exchanger Frames, Enhance Flexibility and Efficiency

Product Description

Overview

Plate Heat Exchanger (PHE) is a kind of heat exchanger equipment formed by the superposition of multiple metal plates, which is widely used in a variety of industrial fields, including chemical, food, HVAC, energy and other industries. One of the core components of the plate heat exchanger is the “plate frame”, which is the support and sealing part of the entire heat exchanger structure, mainly used to fix the heat exchanger plate, to ensure that the fluid sealing and stability in the heat transfer process.

Plate frame is generally composed of two parts: front frame and rear frame. The front frame usually has an inlet and outlet connection port for connecting pipes, and the rear frame is used to support the heat exchanger plate to ensure the sealing and pressure distribution between heat exchanger plates.

Features

1. Simple and compact structure: the plate frame of plate heat exchanger has a simple structure, but with high strength and sealing performance. By stacking multiple heat exchanger plates, the plate frame can ensure the compactness and high efficiency of the whole heat exchanger.

2. Removability and maintainability: As the structure of the plate heat exchanger is designed to be removable, the plate frame makes the heat exchanger easy to clean, overhaul and maintain when needed. Especially in industrial applications, where the cleanliness of the heat exchanger is critical, the plate frame is designed to be removable to effectively reduce maintenance costs.

3. Flexibility and scalability: As the plate heat exchanger plate frame design can increase or decrease the number of heat exchanger plates as needed, which makes the plate heat exchanger can flexibly respond to different heat exchange needs. When the demand for heat exchange increases, the heat exchange capacity can be easily enhanced by increasing the number of plates.

4. Excellent sealing: The sealing gasket or sealing ring on the plate frame ensures the isolation between the internal and external fluids of the plate heat exchanger and prevents cross-contamination of the fluids. The sealing design also helps to improve heat transfer efficiency and avoid leakage.

5. Corrosion and high-pressure resistance: plate and frame are usually made of corrosion-resistant, high-temperature-resistant materials (such as stainless steel, titanium alloy, etc.), making it possible to work stably for a long time at high temperatures, high pressures, and corrosive working conditions.

6. Easy operation: the design of the plate and frame makes the operation of the equipment easier, and the import and export pipelines can be adjusted according to the need for orientation, which can reduce the space occupied during operation.

7. Efficient heat exchange performance: plate heat exchanger compared to the traditional shell and tube heat exchanger, the design of the flow channel between the plate and the plate can effectively increase the degree of turbulence of the fluid, thus improving the heat exchange efficiency. Due to the fixed role of the plate frame, so that the heat exchange plate in operation to maintain good contact with the flow channel convection, to ensure that the heat exchange effect.

8. Uniform pressure distribution: the design of the plate frame makes each heat exchanger plate is subject to uniform pressure distribution, to ensure that the entire heat exchanger in the working process of stable operation, to avoid local pressure is too high or too low to cause damage.

The plate frame of the plate heat exchanger, as one of the core structures of the heat exchanger, is equipped with a number of important functions, such as support, sealing, easy operation, etc., which can ensure that the equipment works efficiently and stably. It not only improves the heat transfer efficiency, but also makes the heat exchanger has high maintainability and adaptability, widely used in various industrial fields.
