Plate And Frame Heat Exchanger Introduction

  There are many types of heat exchangers. Plate heat exchangers are used in a wide range of applications, such as geothermal heating, radiators, and Plate and frame heat exchanger introductioncentral air conditioning. At the same time, plate heat exchangers or plate heat exchanger units are also widely used in bathing, metallurgy, hydraulic, chemical, pharmaceutical, food and other fields.

  The main components of the plate heat exchanger are composed of heat exchange plates, sealing pads, clamping plates, guide rods and clamping bolts. The heat exchange plate is pressed and formed by a stainless steel plate, and it has four flow passage holes at the top and the bottom, and an adult-shaped corrugation in the middle, and a seal groove is pressed around the periphery. A sealing gasket is adhered to the sealing groove.The heat exchange plates are aligned by two guide rods, and the two clamping plates press the plates through the clamping bolts to form a heat exchange passage of the heat exchanger inner cavity.In the opposite direction of the herringbone corrugation direction of the adjacent heat exchange plates, the contact points support each other.The herringbone corrugations and these support points cause the turbulent flow to form well when the fluid medium flows inside, which is the main reason for the high heat exchange efficiency of the plate heat exchanger.In addition, the thickness of the heat exchange plate is thin, the heat conduction heat resistance is small, and the fluid medium flow distribution on both sides of the plate is relatively balanced, which also makes the heat transfer more sufficient.
