Abstract
The invention discloses a plate heat exchanger nickel brazing production line and its process. The plate heat exchanger nickel brazing production line is sequentially composed of a roller coating machine, a No. 1 tunnel oven, a spot coater, a No. 2 tunnel oven, and a brazing furnace. And the equipment is connected by a transmission belt; the nickel brazing process of the plate heat exchanger includes: rolling coating, primary drying, primary cooling, spot coating, assembly, secondary drying, secondary cooling, brazing, and quality inspection. The invention has the advantages of good welding strength, high efficiency, high yield and the like.
Description
technical field [0001] The invention relates to a production process of a plate heat exchanger, in particular to a nickel brazing production process of a plate heat exchanger. Background technique [0002] Plate heat exchanger is an ideal equipment for liquid-liquid and liquid-vapor heat exchange. It has a series of advantages such as high heat exchange efficiency, small heat loss, compact and light structure, small footprint, and long service life. Widely used in metallurgy, mining, petroleum, chemical industry, electric power, medicine, food, chemical fiber, papermaking, textile, shipbuilding, heating and other departments. Moreover, it can be used in various situations such as heating, cooling, evaporation, condensation, sterilization, and waste heat recovery. There are two main types of plate heat exchangers: detachable and welded. In comparison, welded heat exchangers have the advantages of strong temperature and pressure bearing capacity and good corrosion resistance....
