Abstract

The invention relates to a plate-connected plate heat exchanger. The plate-connected plate heat exchangercomprises end pressing plates and heat exchange plate bundles, and the heat exchange plate bundlesare disposed between the end pressing plates.The plate-connected plate heat exchanger further comprises communication plate bundles. The heat exchange plate bundles are arranged at intervals between the end pressing plates. The plurality of sets of heat exchange plate bundles are connected to each other in a series, parallel or parallel serial manner by the communication plate bundles, and theheat exchange plate bundles and the communication plate bundles are clamped and fixed by the end pressing plates.According to the plate-connected plate heat exchanger, the problem that the large heatexchange plate is easy to be deformed and water leakage occurs can be overcome, the maintenance workload and cost reduction are facilitated, the service life of the heat exchanger is prolonged, heat exchange efficiency is high, and combination is flexible. A matching custom function is realized according to the requirements, installation environment and other needs, the structure is compact, the space is small, and the transportation is more convenient.

Description

technical field [0001] The invention belongs to the technical field of plate heat exchangers, and in particular relates to a plate heat exchanger of a connected plate type. Background technique [0002] At present, in the HVAC industry, the mass of the heat exchanger accounts for more than 30% of the total mass of the unit, and the power consumption in heat exchange accounts for about 25% of the total power consumption. Therefore, improving heat exchange efficiency and reducing energy waste has become a heat exchanger primary issue. [0003] Among many types of heat exchangers, plate heat exchangers are widely used because of their high heat transfer coefficient, wide adaptability, compact structure, and convenient maintenance. Generally speaking, the heat transfer coefficient of the plate heat exchanger is 3 to 5 times that of the shell and tube type. However, there are many problems in the plate heat exchanger, such as external leakage, liquid flow, large pressure drop, a...
