A heat exchange structure with symmetrical features, heat exchanger and application method thereof

Abstract

The invention provides a heat exchange structure with corresponding features, which is composed of multiple fins, sealing bodies and structural tubes, and has at least one of the following corresponding features: two sets of corresponding heat exchange tubes and fins, heat exchange The tubes run through the fins, and the corresponding heat exchange tubes are fixedly connected to the fins; or have corresponding two sets of channels, and the two sets of channels are used as auxiliary channels and gas channels respectively; or the functional elements are arranged symmetrically; or the functional elements contain TEC elements that can be Symmetrical switching; or heat exchange tubes that can switch flow directions symmetrically or open-flow switching; or have heat recovery sections that are symmetrically arranged, and the heat recovery sections are composed of two adjacent channels. Its applications include defrosting, reheating, air sterilization, waste heat recovery, refrigeration and heating, power generation, solar energy utilization and energy storage, etc. The heat exchange structure of the present invention is economical, reliable, highly efficient and energy-saving, can be applied to traditional air treatment, and at the same time lead to new application fields, and will produce significant economic and energy-saving benefits and environmental and social benefits.

Description
