Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] figure 1 A heat storage heat exchanger is shown, the heat exchanger includes a shell 16, a heat storage medium 15, a fluid channel, the heat storage medium 15 is located in the shell 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 f(x) a derivative.

[0029] If the fluid is a high-temperature fluid, as the fluid flows, the temperature of the fluid will gradually drop, so its heat release capacity will gradually decrease, and th...

Abstract

A heat storage heat exchanger comprises a shell, a heat storage medium and a fluid channel. The heat storage medium is located in the shell. The fluid channel is located in the heat storage medium and provided with a fluid inlet and a fluid outlet. The heat storage capability of the heat storage heat exchanger is gradually improved along with the flowing direction of fluid. According to the heat storage heat exchanger, the capabilities of absorbing a large amount of latent heat and long-term circulation use of a phase-change material are fully utilized, unnecessary extra energy consumption is avoided, and the temperature of fresh air makes people feel comfortable; a system is high in heat exchanging efficiency, free of pollution, environmentally friendly and capable of saving energy.

Description

technical field [0001] The invention belongs to the field of heat exchangers, in particular to a heat storage heat exchanger. Background technique [0002] With the rapid development of our country in the past few years, energy consumption is increasing, and energy waste is increasing, so it is urgent to design a heat storage heat exchanger for energy recovery. However, the heat storage materials of the heat accumulators in the prior art all have the same heat storage capacity, resulting in uneven heat storage on the whole of the heat accumulator, which will cause excessive heat storage, for example, the temperature near the inlet of the high-temperature fluid is too high , the life of the part will be reduced for the fluid pipeline and the heat accumulator. [0003] In addition, my country's air pollution is becoming more and more serious, and severe air phenomena such as sandstorms and smog are becoming more and more serious. Three-quarters of urban residents cannot absor...
