Brazed plate heat exchangers are an evolution of detachable heat exchangers. The sealing material is changed from a rubber pad to copper, and all the plates are bonded together by copper solder. Just as all the contact points of the detachable heat exchanger plate must be tightly fitted, all the contact points of the brazed heat exchanger must be completely welded together, so as to ensure high heat exchange efficiency of the heat exchanger. And the ability to withstand pressure, but also to achieve a long service life.
The copper brazed plate heat exchanger is similar to the all-welded plate heat exchanger. It also has no gasket. It is suitable for high temperature and high pressure work conditions and can not be repaired and cleaned. The difference lies in the plate of all welded plate heat exchanger. It is formed by argon arc welding, and the plate of the brazed plate heat exchanger is formed by high temperature fusion welding of copper foil. The volume of the copper brazed plate heat exchanger is usually smaller than that of the all welded plate heat exchanger. Copper brazed plate heat exchanger is a new type of equipment in the field of heating and cooling. In addition to the general advantages of plate heat exchanger (small footprint, compact structure, high heat transfer efficiency), its ability to handle small temperature differences is also Very prominent, is an energy-saving product.
