Brazing, which is a welding method that after brazing filler metal lower than the melting point of a weldment and the weldment are heated to the melting temperature of the brazing filler metal at the same time, the liquid brazing filler metal is used for filling the gaps of solid workpieces to connect the metals. During brazing, an oxide film and oil stains on a contact surface of a base material are removed firstly, so that a capillary tube can play a role after the brazing filler metal is melted, and the wettability and the capillary fluidity of the brazing filler metal are improved. Brazing is divided into brazing and soldering according to the melting point of the brazing filler metal. The brazing deformation is small, the joint is smooth and attractive, and the method is suitable for welding components which are precise, complex and composed of different materials, such as honeycomb structural plates, turbine blades, hard alloy cutters, printed circuit boards and the like. Before brazing, the workpiece must be carefully processed and strictly cleaned to remove oil stains and an excessively thick oxidation film, so that the assembly gap of the interface is ensured. The gap is generally required to be between 0.01 and 0.1 mm.
The brazed plate heat exchanger is a new type high-efficiency heat exchanger formed by stacking a series of metal sheets with certain corrugated shapes and performing brazing processing. Thin rectangular channels are formed between the various plates through which heat is exchanged. Compared with the conventional shell-and-tube heat exchanger, the heat transfer coefficient of the heat exchanger is much higher under the same flow resistance and pump power consumption. Brazing plate heat exchanger is when brazing, if do not adopt the backup pad to support the sheetmetal bottom, the sheetmetal closed assembly is comparatively troublesome, if adopt the backup pad to support the sheetmetal, the brazing filler metal after melting probably flows downwards under the effect of gravity, and the brazing filler metal probably adheres in the backup pad of sheetmetal below, leads to being connected between sheetmetal and the backup pad of below, and the later stage is dismantled comparatively trouble.
Based on this, the utility model designs a high performance brazed plate heat exchanger to solve the above-mentioned problem.
