Because the temperature of the circulating air is gradually increased in the heat storage body along the flowing direction of the circulating air, the heat stored in the heat storage body is gradually increased, so that the heat storage body generates front and back temperature difference, and the heat storage density of the whole heat storage body is reduced. In order to ensure sufficient heat storage capacity for heat supply, the material usage of the heat storage body needs to be increased, resulting in increased equipment cost.

Detailed Description
The invention will now be described in more detail by way of example with reference to the accompanying drawings in which:
with reference to fig. 1, the invention relates to a high-heat-storage-density solid-state heat storage device structure with partitioned arrangement, wherein a heat storage body surrounded by heat insulation materials 4 is divided into a side storage and side discharge area 6 and a single-position and single-discharge area 5. Under the condition of simultaneous storage and release, circulating air generated by the variable frequency fan 1 enters the simultaneous storage and release area 6 for heat exchange after passing through the fan air outlet 2 and the three-way valve 3, enters the heat exchanger 8 for heat release after passing through the three-way valve 9 and the heat exchanger air inlet 10, and enters the variable frequency fan 1 through the return air duct 7 to complete circulation.
Under the working condition of simultaneous storage and release, the three-way valve 3 controls the circulating air to flow through the simultaneous storage and release area 6 only, and at the moment, the single release area 5 at one position is only heated and is not influenced by the flowing of the circulating air, and the areas are uniformly heated; under the working condition of heat release, the three-way valve 3 is completely opened, and circulating air passes through the single discharge area and the side storage and side discharge areas at the same time, so that the heat of the whole heat storage body is completely released. The invention basically eliminates the temperature gradient of a single-place single-discharge area, improves the heat storage capacity of the whole heat storage body, and can effectively reduce the consumption of heat storage materials and the cost of the device under the requirement of the same heat storage capacity.
