Product Description
The plate and shell heat exchanger is a heat exchanger with a plate tube as a heat transfer element, also known as a sheet heat exchanger. It is mainly composed of two parts: plate tube bundle and shell. The contact points of cold-formed pairs of slats are tightly welded together to form a plate tube containing multiple flat runners. Many plates and tubes of different widths are arranged in a certain order. In order to maintain the spacing between the plates and tubes, metal strips are inserted at both ends of the adjacent plates and tubes and welded together with the plates and tubes.
Features
① High effiency of heat transfer capability.
With the plate as the heat transfer surface, the heat transfer efficiency is good. The heat transfer coefficient is about twice that of the shell and tube heat exchanger.
② Compact structure and small volume.
③ Temperature and pressure resistance.
The highest working temperature can reach 800 ℃, and the highest working pressure can reach 6.3 MPa.
④ Easy to clean.
The fluid in the flat flow channel flows at high speed, and the surface of the plate is smooth, it is not easy to scale, the plate bundle can be removed, and the cleaning is convenient.
