Plate type air-to-air heat exchanger made of polymer PP material

The plate type air-to-air heat exchanger made of polymer PP (polypropylene) material is a heat exchange device based on polypropylene material, mainly used for heat exchange between gases. Here are its main features and application areas:

Main features:
Corrosion resistance: PP material has strong chemical corrosion resistance and is suitable for acidic or alkaline gas environments, especially performing well in industrial environments with strong corrosiveness.

Lightweight: Compared to metal heat exchangers, PP material heat exchangers are lighter in weight, making them easier to install and maintain.

Good thermal stability: Polypropylene has good thermal stability and can typically operate within a temperature range of -10 ° C to+95 ° C.

High cost-effectiveness: Due to the low cost of PP material and relatively easy processing, the overall cost is relatively economical.

Environmental friendliness: Polypropylene is a recyclable polymer material with minimal impact on the environment after disposal.

Main application areas:
Chemical and pharmaceutical industries: used for heat recovery or temperature regulation of corrosive gases.
Exhaust gas treatment system: During the air purification process, heat is recovered from harmful gases through a heat exchanger.
Food processing: In some food production processes, it is used for gas exchange to maintain the stability of environmental temperature.
HVAC system: Used in the ventilation and air conditioning systems of buildings for air preheating or pre cooling, improving energy efficiency.
The plate type air-to-air heat exchanger made of polypropylene material has become an ideal choice for many specific industrial fields due to its unique corrosion resistance and good cost-effectiveness.

Working principle of plate air-to-air heat exchanger

Plate air-to-air heat exchanger is a commonly used heat exchange equipment, and its working principle is as follows:

The plate air-to-air heat exchanger is composed of a series of parallel metal plates, and a series of channels are formed between the plates. The heat medium flows in these channels. When the heat medium flows in the plate air-to-air heat exchanger, the heat medium transfers heat to the plate, and then the plate transfers heat to the other side of the heat medium, thereby achieving heat transfer and heat exchange.

The working principle of the plate air-to-air heat exchanger can be divided into two ways: direct heat transfer and indirect heat transfer.

Direct heat transfer: Direct heat transfer refers to the heat medium flowing directly through the plate, transferring heat to the other side of the heat medium. This method is suitable for situations where the temperature difference between the two sides of the heat medium is small.

Indirect heat transfer: Indirect heat transfer refers to the heat medium transferring heat to the other side of the heat medium through the plate. This method is suitable for situations where the temperature difference between the two sides of the heat medium is large.

In the plate air-to-air heat exchanger, the flow of the heat medium has two ways: one-way flow and two-way flow. One-way flow means that the heat medium flows in only one direction, while two-way flow means that the heat medium can flow in two directions. Plate air-to-air heat exchangers with two-way flow have higher heat exchange efficiency, but they are also more complex and expensive.

In summary, the plate air-to-air heat exchanger achieves heat transfer and heat exchange between heat media through the channels between plates. Its working principle can be divided into direct heat transfer and indirect heat transfer, and the flow of the heat medium has one-way flow and two-way flow.
