Plate heat exchanger

    Plate heat exchanger is a type of heat exchanger composed of a series of metal sheets with a certain ripple shape stacked together. Thin rectangular channels are formed between various plates for heat exchange. Plate heat exchanger is a device for heat exchange between liquid liquid and liquid vapor. It has the characteristics of high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, convenient installation and cleaning, wide application, and long service life. Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of a tubular heat exchanger, occupying one-third of the area of a tubular heat exchanger, and the heat recovery rate can reach over 90%.

Product introduction

Plate heat exchanger is a type of heat exchanger composed of a series of metal sheets with a certain ripple shape stacked together. Thin rectangular channels are formed between various plates for heat exchange. Plate heat exchanger is a device for heat exchange between liquid liquid and liquid vapor. It has the characteristics of high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, convenient installation and cleaning, wide application, and long service life. Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of a tubular heat exchanger, occupying one-third of the area of a tubular heat exchanger, and the heat recovery rate can reach over 90%.

Operational principle

The working principle of a plate heat exchanger is based on the heat transfer mechanism. According to thermodynamic laws, heat is always spontaneously transferred from a high-temperature object to a low-temperature object. Two fluids with different temperatures flow in separate spaces on the wall, promoting heat transfer between the two fluids through wall heat conduction and fluid convection on the wall surface. A heat exchanger made by pressing thin metal plates into heat exchange plates with a certain ripple shape, then stacking them and fastening them with clamps and bolts. Thin rectangular channels are formed between various plates for heat exchange through half plates. The working fluid flows through a narrow and tortuous channel formed between two plates. Cold and hot fluids pass through the flow channel in sequence, with a partition plate in the middle separating the fluid and conducting heat exchange through this plate.

Product features

The features include compact structure, small footprint, high heat transfer efficiency, high operational flexibility, wide application range, low heat loss, and convenient installation and cleaning.
