Brazed plate heat exchanger has defects, it can not be disassembled and cleaned, can not be repaired, the price is slightly higher. The brazed plate heat exchanger can be composed of different steps according to different main parameters to improve its heat transfer efficiency.

The brazed plate heat exchanger has no sealant pad, the plate is welded with copper Bo high-temperature melting electric welding, the plate has a circular curved wavy design scheme, which can make the fluid mechanics in low water flow can also complete the seepage, heat transfer efficiency. The volume of brazed plate heat exchanger is generally small, and the key application is in ultra-high pressure, and the leather pad can not be integrated into the working condition.

The steps of its fluid mechanics in the plate can be composed of many aspects according to the actual application situation, and it is generally composed of single step and multi-step. If the material on both sides is symmetrical in a single step, one side of the material can be a single step and the other side of the material can be a double step, and both sides of the material can be composed of different steps. The specification composition of the brazed plate heat exchanger is that the hot and cold sides are single steps, and multi-step heat exchangers can also be tailored according to customers' requirements.

The method of step composition should be calculated according to heat transfer and hydrodynamic friction resistance, and the convective heat transfer index in the cold and hot flow channels should be the same or close to each other as far as possible, so as to have good heat conduction. Because the convective heat transfer index on both sides of the heat conduction surface is the same or close, the thermal conductivity is very large.

Although the flow rate of brazed plate heat exchangers varies from plate to plate, the average flow rate is still used to calculate heat transfer and hydrodynamic friction resistance. Because the "U" shaped single step docking is fixed on the clamping plate, disassembly is convenient.
