The box body 2 is a hollow shell with two open ends, the two ends are respectively used as a main port for the first medium to enter and exit, and the main port is hermetically connected with the outer shell of the box body 2. The plurality of heat storage units 1 are arranged in parallel inside the case 2. The heat storage unit 1 is used for realizing the heat storage and heat release functions of the medium in a matching manner.
Each heat storage unit 1 specifically comprises a heat storage and exchange body 11 and a shell 12. The heat storage and exchange body 11 is a hollow platform structure with two open ends, a contraction-shaped inner channel for the circulation of the first medium is formed inside the hollow platform structure, and two ends of the inner channel are respectively communicated with the two main ports. The shell 12 is a hollow cylinder with two open ends, coaxially sleeved outside the heat storage and exchange body 11, and a gap between the inner wall of the shell 12 and the outer wall of the heat storage and exchange body 11 forms an outer channel for a second medium to pass through, wherein the outer channel is in a contraction shape; two ends of the heat storage and exchange body 11 extend out of two ends of the shell 12, and the inner channel is not communicated with the outer channel. The inner channel and the outer channel are not communicated, so that the two media cannot be polluted mutually, and the cleanness of each medium is ensured.
The heat storage and exchange body 11 is made of solid heat storage materials, phase change materials or liquid heat storage materials, a metal shell can be wrapped outside the heat storage and exchange body 11, and the heat storage materials and the metal shell form the heat storage and exchange body 11 together. The heat storage and exchange body 11 can realize the function of heat storage. For example, the heat storage and exchange body 11 may be of a ceramic or high temperature concrete structure. The shell 12 is made of heat insulating material, which can better preserve the stored heat of the whole structure, and can be modified perlite or calcium silicate. In specific implementation, a metal shell can be additionally arranged outside the shell 12 according to actual needs.
Two orifice plates III5 are respectively located in the box 2 and are provided at both ends of the housing 12. As shown in fig. 5, each orifice plate III5 is a flat plate provided with a plurality of through holes III, and each through hole III on each orifice plate III5 communicates with a port of each housing 12 on the same side.
Two baffles are respectively positioned in the box body 2 and arranged at two ends of the heat storage and exchange body 11, each baffle is a flat plate provided with a plurality of through holes, and each through hole on each baffle is communicated with the port of each heat storage and exchange body 11 at the same side. And a second medium main port communicated with the outer channel port is formed between the adjacent baffle and the orifice plate III5, so that the inner channel and the outer channel can be sealed and isolated.
The flow channels of the first medium are each inner channel and the total ports at two ends of the inner channel, and the flow channels of the second medium are each outer channel and the total ports of the second medium at two ends of the outer channel.

In practical use, the first medium and the second medium can be a high-temperature medium and a low-temperature medium respectively to complete heat storage and heat release functions respectively; or the first medium and the second medium can be a low-temperature medium and a high-temperature medium respectively to complete the heat storage and the heat release functions respectively.
Because the high-temperature medium releases heat to the heat storage material, the volume of the high-temperature medium also decreases along with the decrease of the temperature of the high-temperature medium, and if the high-temperature medium is in a channel with the same cross section, the flow speed of the high-temperature medium also gradually decreases, and the heat transfer is weakened. However, in the tapered passage of the present invention, since the sectional area of the passage is gradually reduced, the flow velocity of the high-temperature medium is substantially constant, and the heat transfer efficiency is high. Similarly, when the low-temperature medium takes heat from the heat storage material, the volume of the low-temperature medium gradually increases as the temperature of the low-temperature medium increases, and the flow velocity of the low-temperature medium is constant in the outer channel with the variable cross section, so that the heat transfer efficiency is high.
Therefore, in practical applications, it is noted that the high-temperature medium needs to pass from the end of the channel with the larger opening area to the end with the smaller opening area; the cryogenic medium needs to pass from the end of the channel with the smaller open area to the end with the larger open area. According to the invention, the inner channel and the outer channel are arranged in a channel structure with a contracted section, so that the flow velocity of a high-temperature medium or a low-temperature medium is stable, and the heat transfer efficiency is high.
