Abstract

The invention provides a regenerative heat exchanger and a fresh air system. The regenerative heat exchanger comprises a heat source inlet, a heat source outlet, a cold source inlet, a cold source outlet and a shell, a plurality of heat storage blocks are arranged in the shell of the heat exchanger, the multiple heat storage blocks are stacked together, a first hole and a second hole are formed ineach heat storage block and do not communicate with each other, the first holes of the multiple heat storage blocks form a communicating channel, the channel formed by the first holes is used for circulating a heat source, and the second holes form a communicating channel to circulate a cold source; and the heat source enters from the heat source inlet, passes through the first holes and then isdischarged from the heat source outlet, and the cold source enters from the cold source inlet, passes through the second holes and then is discharged from the cold source outlet. According to the novel regenerative heat exchanger, independent heat storage and heat exchanging can be conducted through the heat storage blocks, heat-exchanging pipes are omitted, and the heat-storage and heat-exchanging effects can be further improved.

Description

technical field [0001] The invention belongs to the technical field of heat exchangers, in particular to a heat storage heat exchanger and a fresh air system. Background technique [0002] With the continuous development of the economy and the massive consumption of energy, energy conservation has become a topic of global concern. Renewable energy such as solar energy, wind energy, and geothermal energy, and the utilization of industrial waste heat and waste heat have become the focus of research and development in various countries. However, these energy sources have Due to the characteristics of discontinuity and instability, the research on energy storage technology is particularly important. Heat storage technology is one of energy storage technologies, and an important part of heat storage technology is the design of phase change heat storage heat exchanger. The common phase change regenerative heat exchanger consists of two tubes set together, and the cold and hot flu...
