Heat exchanging structure with corresponding features as well as heat exchanger and application method thereof

Abstract

The invention provides a heat exchanging structure with corresponding features. The heat exchanging structure is composed of a plurality of fins, a sealing body and a structural pipe and at least hasone of the following corresponding features: the heat exchanging structure is provided with two groups of corresponding heat exchanging pipes and fins, the heat exchanging pipes penetrate through thefins, and the corresponding heat exchanging pipes are fixedly connected with the fins; or the heat exchanging structure is provided with two groups of corresponding passages and the two groups of passages serve as an auxiliary passage and a gas passage separately; or functional elements are symmetrically arranged; or the functional elements comprise TEC elements to be symmetrically switched; or the heat exchanging structure is provided with heat exchanging pipes capable of symmetrically switching the flow directions or switching between flow break and open flow; or the heat exchanging structure is provided with symmetrically arranged heat recovery sections, and each of the heat recovery sections is composed of two adjacent passages. Application of the heat exchanging structure comprises defrosting, heat regeneration, air sterilization and disinfection, waste heat recovery, refrigeration and heating, power generation, solar energy utilization, energy storage and the like. The heat exchanging structure is economical and reliable, efficiently saves energy, can be used for traditional air treatment, and can guide out a new application field to generate remarkable economic and energy-saving benefits and environmental and social benefits.
