All Welded Plate Heat Exchanger

The emergence of welded plate heat exchanger provides a new option for users of traditional tubular heat exchangers, whose biggest advantage is to have a high heat exchange efficiency of plate heat exchanger and high temperature and pressure resistance of tube heat exchanger. Compared with the tube heat exchanger, welded plate heat exchanger can provide users with more economical and more space-saving products.           Hofmann’s welding plate heat exchanger products uses similar corrugated plate structure of plate heat exchanger, at the same time uses more advanced metal welding process sealing, non-rubber gasket design, a variety of metals and alloys, which make the product suitable from -50 ℃ to 500 ℃, up to 4.0MPa working pressure of most heat transfer conditions. It can be applied to liquid, gas, steam and two-phase mixed fluids, including highly corrosive media, organic solvents, and conditions that high temperature steam shim heat exchangers cannot be applied to.

The Features Of The Vertical Condenser And Shower-Type Condenser

Vertical shell and tube condenser

The main features of the vertical condenser are: 1)Due to the high cooling flow and flow rate, the heat transfer coefficient is high, generally about K = 600 ~ 700 (kcal / m2? H? ℃). 2)Vertical installation covers small areas, and can be installed outdoors. 3)Cooling water flow directly and have high flow rate, so not need high water quality, the general water can be used as cooling water. 4)Scales in pipe can be easy removed, and do not have to stop the refrigeration system work.

Why does the central air conditioning system must use plate heat exchanger?

First, the fluorine - water heat exchanger in the water system air conditioning host, plays with the secondary refrigerant heat transfer effect. Generally there are three forms of heat exchanger, A. double pipe heat exchanger; B. shell and tube heat exchanger; C plate heat exchanger. A and B are generally used in large units, with small pressure loss, low water quality requirements, not easy to plug, C general used in small units, with small size, high efficiency, But the water quality requirements are also high. The water system host, must have a heat exchanger, if not the plate must also be other type.
