Embodiment Construction

[0031] The present invention will be further described below in conjunction with the drawings.

[0032] figure 1 A heat storage heat exchanger is shown. The heat exchanger includes a housing 16, a heat storage medium 15, and a fluid channel. The heat storage medium 15 is located in the housing 16, and the fluid channel is located in the heat storage medium 15. The fluid channel has a fluid inlet 17 and an outlet 18, wherein along the flow direction of the fluid, the heat storage capacity of the heat storage medium 15 gradually increases, that is, the heat storage capacity of the heat storage heat exchanger is S, Set the heat storage capacity S as a function of the distance from the fluid inlet x, that is, S=f(x), in the heat storage heat exchanger, f'(x)> 0, where f'(x) is the first derivative of f(x).

[0033] If the fluid is a high-temperature fluid, the temperature of the fluid will gradually decrease with the flow of the fluid, so its heat release capacity will gradually decrea...

Abstract

The invention relates to a heat storage heat exchanger. The heat exchanger comprises a shell, a heat storage medium and a fluid passage, wherein the heat storage medium is arranged in the shell, the fluid passage is arranged in the heat storage medium, the fluid passage is provided with a fluid inlet and a fluid outlet, and the heat storage medium is a phase-changing heat storage medium. By adopting the heat storage heat exchanger, the capacity of the phase-changing material for absorbing a great amount of potential heat and capable of being recycled for a long time is utilized, so that the consumption of unnecessary additional energy is avoided, and the temperature of fresh air is more comfortable; the system is high in heat exchanging efficiency, pollution-free, energy-saving and environment-friendly.

Description

Technical field [0001] The invention belongs to the field of heat exchangers, and particularly relates to a heat storage heat exchanger. Background technique [0002] With the rapid development of our country in the past few years, energy consumption has become larger and larger, and as energy is wasted more and more, it is urgent to design a heat storage heat exchanger for energy recovery. The heat storage materials of the heat accumulators in the prior art all have the same heat storage capacity, which results in uneven heat storage in the heat accumulator as a whole, which will cause excessive heat storage locations, such as high temperature near the inlet of high-temperature fluid. , The fluid pipeline and heat accumulator will reduce the local life. [0003] In addition, my country’s air pollution has become more and more serious, and severe air phenomena such as sandstorms and haze have become more and more serious. Three-quarters of urban residents cannot absorb clean air. ...
