Description

Technical Field

[0001] The utility model relates to the technical field of heat transfer and heat transfer engineering, in particular to a plate-type heat exchange device. Background Art

[0002] The functions of plate heat exchangers mainly include heat transfer, temperature control, energy utilization, fluid processing and space saving. They are widely used in industrial production, chemical industry, HVAC and other fields.

[0003] Although current technology has many advantages, the disadvantage of current technology is that the plate-type heat exchanger does not have self-cleaning ability, and the fluid will encounter a certain resistance when passing through the plate-type heat exchanger. The formation of resistance will cause a pressure drop inside the plate-type heat exchanger, and the pressure drop will hinder the flow of the fluid, reduce the heat transfer coefficient, and reduce the heat exchange efficiency. The reduction in pressure drop makes it easier for impurities to remain inside the plate-type heat exchanger, causing the pipes of the plate-type heat exchanger to be blocked. At the same time, when the plate-type heat exchanger vibrates, the contact between the plates will be loose, resulting in an increase in heat transfer resistance, further reducing the heat transfer efficiency, and making it easier for impurities to remain in the gaps between the plates, exacerbating the accumulation of impurities.
