Abstract
The utility model provides a high-efficient solid-state heat-retaining device with air current constant voltage, belongs to solid-state heat-retaining field to solve present solid-state heat-retaining device's air intake and not carry out the design of air current constant voltage structure, the amount of wind that the air volume that solid heat storage material layer lower extreme passes through in the in-service use is big than the amount of wind that the upper end passes through, makes whole solid heat storage material lower extreme cool down faster than the upper end, leads to appearing the inhomogeneous phenomenon of heat dissipation on solid heat storage material layer, influences solid-state heat-. The heat storage brick comprises a heat insulation layer and heat storage bricks, wherein the heat storage bricks are stacked to form a heat storage wall, a plurality of cavities are arranged in the heat storage wall, the cavities are sequentially arranged along the heat storage wall from bottom to top and are arranged in a matrix manner, the heat insulation layer is arranged outside the heat storage wall, a certain gap is formed between the heat storage wall and the heat insulation layer and communicated with the cavities to form an air duct, and the gaps between the heat insulation layer and the two sides of the heat storage wall are gradually reduced from bottom to top in the vertical direction.
Description
Technical Field
The invention relates to a heat storage device, in particular to a high-efficiency solid-state heat storage device with constant airflow pressure.
Background
At present, an air inlet of the solid-state heat storage device is not designed with an air flow constant-pressure structure, and the air volume passing through the lower end of a solid heat storage material layer is larger than that passing through the upper end in actual use, so that the lower end of the whole solid heat storage material layer is cooled faster than the upper end, the phenomenon of uneven heat dissipation of the solid heat storage material layer is caused, and the service life and the heat exchange efficiency of the solid-state heat storage device are influenced.
Disclosure of Invention
The present invention provides a high-efficiency solid-state heat storage device with constant airflow pressure to solve the above problems.
The technical scheme adopted by the invention for solving the technical problems is as follows:
the utility model provides a high-efficient solid-state heat-retaining device with air current constant voltage includes heat preservation and heat-retaining brick, heat-retaining brick layer stack builds and forms the heat-retaining wall, heat-retaining wall inside is equipped with a plurality of cavitys, supreme arranging in proper order is followed down along the heat-retaining wall to a plurality of cavitys, be the matrix mode and arrange, the outside of heat-retaining wall is equipped with the heat preservation, be certain clearance setting between heat-retaining wall and the heat preservation and link up the formation wind channel with a plurality of cavitys, supreme reducing gradually is followed along vertical direction down in the clearance of heat preservation and heat-retaining wall both sides, the wind.
Compared with the prior art, the invention has the following beneficial effects:
outside wind gets into from the air intake, and wind will flow out along heat-retaining wall bottom from supreme cavity down in proper order, because the clearance of heat preservation and heat-retaining wall reduces gradually, and the wind pressure will remain unchanged. Similarly, the wind pressure in the wind outlet from top to bottom will also be kept consistent. Meanwhile, as the sizes of the cavities of the heat storage wall from top to bottom are consistent, the wind speed is kept consistent under the same wind pressure. Therefore, the heat in the solid heat storage material is quickly and uniformly released, the heat exchange efficiency of the solid heat storage device is improved, the service life of the solid heat storage material is prolonged, and the benefit is improved.

Detailed Description
The invention will be described in further detail below with reference to the accompanying drawings: the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation is given, but the scope of the present invention is not limited to the following embodiments.
Example 1: as shown in fig. 1, this embodiment a high-efficient solid-state heat-retaining device with air current constant voltage includes heat preservation 1 and heat-retaining brick 3, heat-retaining brick 3 range upon range of piles up and forms the heat-retaining wall, the inside a plurality of cavities 4 that is equipped with of heat-retaining wall, supreme arranging in proper order is followed along the heat-retaining wall to a plurality of cavities 4, be the matrix mode and arrange, the outside of heat-retaining wall is equipped with heat preservation 1, it sets up and link up formation wind channel with a plurality of cavities 4 to be certain clearance between heat-retaining wall and the heat preservation 1, the clearance of heat preservation 1 and heat-retaining wall both sides is followed supreme reducing gradually from down along vertical direction, the wind.
Specifically, the heat storage brick 3 is made of high-alumina bricks or magnesia bricks. The insulating layer 1 is made of aluminum silicate.
Each cavity 4 is the same size.
Outside wind gets into from the air intake, and wind will flow out along heat-retaining wall bottom from supreme cavity down in proper order, because the clearance of heat preservation and heat-retaining wall reduces gradually, and the wind pressure will remain unchanged. Similarly, the wind pressure in the wind outlet from top to bottom will also be kept consistent. Meanwhile, as the sizes of the cavities of the heat storage wall from top to bottom are consistent, the wind speed is kept consistent under the same wind pressure. Therefore, the heat in the solid heat storage material is quickly and uniformly released, the heat exchange efficiency of the solid heat storage device is improved, the service life of the solid heat storage material is prolonged, and the benefit is improved.
