Tianjin plate heat exchanger_ Factors affecting the heat exchange effect of Tianjin plate heat exchanger
2020-08-04
The plate heat exchanger is a highly efficient heat exchanger made up of a series of metal plates with a certain corrugated shape stacked together. Thin rectangular channels are formed between the various plates, allowing for heat exchange through the plates. The plate heat exchanger is an ideal device for heat exchange between liquid-liquid and liquid-vapor. It features high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, and long service life. _Food-grade plate heat exchanger_ Fully welded plate heat exchanger_ Removable plate heat exchanger
Tianjin plate heat exchangerIt is a high-efficiency heat exchanger made up of a series of metal sheets stacked in a certain wavy shape. Thin rectangular channels are formed between the various plates, allowing for heat exchange through the plates.Tianjin plate heat exchangerIt is liquid—liquid, liquid—vapor is an ideal device for heat exchange. It features high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, and long service life. Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of tubular heat exchangers.3-5times, with a footprint oftubular heat exchangerone-third, and the heat recovery rate can reach above90% _Food-grade plate heat exchanger_ fully welded plate heat exchanger_ detachable plate heat exchanger
Although there are many factors affecting the heat exchange effect, they can ultimately be divided into the following five categories:Tianjin plate heat exchangerThere are many factors affecting heat exchange efficiency, but ultimately, they can be broadly categorized into the following five types:
1, in terms of structure, ifTianjin plate heat exchangerthe structure is unreasonable, it may lead to situations where the cold or hot source cannot fully contact the heat exchange surface, resulting in a large local temperature difference, butTianjin plate heat exchangerthe heat exchange area cannot be fully utilized.Tianjin plate heat exchanger _Food-grade plate heat exchanger_ fully welded plate heat exchanger_ detachable plate heat exchanger
2, in the selection of materials for the heat exchange area, if the wrong material is chosen, we should generally select materials with high heat transfer coefficients and low thermal resistance, but many people inadvertently choose materials with low heat transfer coefficients and high thermal resistance.Tianjin plate heat exchanger _Food-grade plate heat exchanger_ fully welded plate heat exchanger_ detachable plate heat exchanger
3, in operation and maintenance,Tianjin plate heat exchangerscaling may occur during use, and if not cleaned, it will affect the heat exchange effect.
4, the impact of flow rate on heat exchange efficiency,Tianjin plate heat exchangerwhen the flow rates of the fluids on both sides of the heat exchange area are different, if one side has a low flow rate, it will create a thick boundary layer of stagnant fluid, affecting heat exchange.
5, the temperature difference between the heat source and the cold source is too small, which does not meet our requirements forTianjin plate heat exchangerresulting in low heat exchange efficiency.
