Abstract

The invention belongs to the technical field of cooling, and particularly relates to a dividing wall type heat exchanger and application. An existing plate heat exchanger is uneven in cooling, large in temperature difference and still poor in cooling effect. The invention provides the dividing wall type heat exchanger which comprises a first heat exchange plate and a second heat exchange plate, a plurality of first air channels and a plurality of second air channels are arranged between the first heat exchange plate and the second heat exchange plate, and the first air channels and the second air channels are sequentially stacked. The first air channel and the second ventilation channel are arranged in a cross flow mode. Filter screens are arranged at the two ends of the first air channel, and filter screens are arranged at the two ends of the second air channel. The dividing wall type heat exchanger is compact in structure, high in heat transfer coefficient, small in heat transfer temperature difference and good in heat exchange effect.

Description

technical field [0001] The application belongs to the technical field of cooling, and in particular relates to a partition heat exchanger and its application. Background technique [0002] As a device that transfers part of the energy of the hot fluid to the cold fluid, the heat exchanger is widely used in the fields of chemical industry, petroleum, energy power and mechanical equipment. A heat exchanger can be a separate device, such as a heater, cooler and condenser, etc.; it can also be a component of a certain process equipment, such as heat exchangers in waste heat recovery systems and air separation systems figure. The plate heat exchanger has the advantages of high heat transfer coefficient, strong temperature and pressure resistance, small footprint, and the ability to realize heat exchange in various media. It has become the key equipment for efficient use of energy and energy conservation in modern industry. [0003] Most of the existing plate heat exchangers are...
