Coil pipe heat accumulation heat exchanger

Abstract

The invention discloses a coil pipe heat accumulation heat exchanger. The coil pipe heat accumulation heat exchanger comprise a shell, a first uniform flow pipe, a second uniform flow pipe, an outputpipe, an input pipe and a plurality of heat accumulation plates; the first uniform flow pipe and the second uniform flow pipe are correspondingly installed at the two ends of the shell; a snakelike discharging pipe is arranged between the first uniform flow pipe and the second uniform flow pipe; one end of the snakelike discharging pipe is connected to the corresponding first uniform flow pipe; the other end of the snakelike discharging pipe is connected to the corresponding second uniform flow pipe; the side faces of the heat accumulation plates are tightly attached to the snakelike discharging pipe; the first uniform flow pipe is communicated with the output pipe; an outlet of the output pipe stretches out of the upper face of the shell; the second uniform flow pipe is communicated withthe input pipe, and an outlet of the input pipe stretches out of the lower face of the shell; a hot flow output port communicated with an inner cavity of the shell is formed in the upper face of one end of the shell; and the lower face of the other end of the shell is provided with a hot flow input port communicated with the inner cavity of the shell. The coil pipe heat accumulation heat exchangeris compact in structure, the pressure bearing capacity is high, the metal consumption is reduced, the contact area between cold and hot fluid is increased and the contact time between the cold and hot fluid is prolonged, and the heat exchanging effect is improved.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a coil heat storage heat exchanger. Background technique [0002] As the driving force for the advancement and development of human society, energy is closely related to the economy, politics and even the military of countries all over the world. In the past more than a century, the industrial revolution has brought great progress to human society, but at the same time it has also consumed a large amount of non-renewable energy on the earth. [0003] China's total energy resources are relatively rich, but the per capita conventional resources are relatively insufficient, especially oil and natural gas resources are seriously lacking, and the per capita share is far below the world average level. Energy has become a constraint to the sustainable development of my country's economy and society. one of the important factors. [0004] Energy storage technology plays a vital ...
