plate heat exchanger

タイトルまたは説明

The plate heat exchanger is a liquid - liquid, liquid - vapor ideal heat exchange equipment. It has a high heat transfer efficiency, low heat loss, compact and lightweight, covers an wide area of​​applications, long life and other outstanding characteristics. The plate heat exchanger heat transfer coefficient is higher than the tubular heat exchanger **5 timesin the case of the same pressure loss, covers an area of ​​one-third of the tube heat exchanger, heat recovery can be as high as *0% or more. The plate heat exchangers are widely used in metallurgy, petroleum, chemical, food, pharmaceutical, shipbuilding, textile, paper and other industries, heating, cooling, heat recovery, rapid sterilization and other kind quality equipment.

Plate heat exchanger has two main type - frame (reassembly), and brazing, the form of a plate is three main kinds:shaped corrugated board, a horizontal straight corrugated board and tumor-shaped plate.
The plate heat exchanger is composed by a set of corrugated metal plates, board the four corners of the holes, two for heat transfer fluid through. The sheet metal is mounted on one side within the framework of the fixed plate and movable clamping plate, and is clamped with the clamping bolt. On the plate are equipped with a sealing gasket, to seal the fluid passage, and directing a fluid to flow alternately to the respective passage formed within the heat exchange. The flow rate, physical properties of the fluid, pressure drop and temperature difference determines the number and size of the sheet. Corrugated board not only improves the degree of turbulence, and forming a plurality of support points, sufficient to withstand the pressure difference between media. Metal plate and movable clamping plates hanging on the guide rod by the lower guiding bar, rod end is fixed to the support column, many of the advantages of high performance, space saving, energy saving, simple maintenance, plate heat exchanger the industry has been highly popular used.
