However, an existing heat-storing energy-saving device is large in size and high in cost during implementation, and thus the heat-storing energy-saving device needs to be improved.

Summary

Against the aforementioned shortcomings in the prior art, the objective of the present invention is to provide an efficient heat-storing energy-saving device.

In order to achieve the aforementioned objective, the following technical solution is adopted according to the present invention:

An efficient heat-storing energy-saving device, comprising a box body, a heat storage box, air pipes and an inserted fan, where the left side and the right side of the front of the box body each are provided with one air pipe; at least one of the two air pipes is connected with the inserted fan, and each air pipe is provided with a control damper; heat insulation layers are disposed at different orientations of the inner side of the box body, and the heat insulation layers each comprise heat insulation cotton A, heat insulation cotton B, heat insulation cotton C and bottom heat insulation cotton; a base for supporting is arranged below the bottom heat insulation cotton, inner boxes are arranged in the heat insulation layers, and middle heat storage boxes are fixed to the inner boxes.

Preferably, steel wires are arranged in the heat storage boxes, aluminum oxide heat storage balls are evenly arranged on the steel wires, the outer surfaces of the whole heat storage boxes are covered with heat storage box casings, extended parts are positioned at the two ends of the heat storage box casings respectively, and after the heat storage boxes are placed in the inner boxes, S-shaped air channels are formed in the box body.

The present invention has the advantages that the efficient heat-storing energysaving device provided by the present invention herein is a small low-cost efficient heat-storing energy-saving device designed with the aluminum oxide heat storage balls as the core. During operation, when hot air passes across the heat storage balls, numerous small balls divide the air flow into very small streams; when the air flows in a heat storage body, strong turbulence is formed, and thus a boundary layer on the surface of the heat storage body is effectively broken through; besides, the balls are very small in ball diameter, small in conduction radius and thermal resistance, high in density and good in heat conductivity, and thus thermal energy in the hot air is timely absorbed. When the stored thermal energy needs to be utilized, the fan blows air reversely, and when cold air passes across the heat storage balls having stored heat well, the cold air will take away thermal energy inside the heat storage balls.

Description of Embodiments

Embodiments of the present invention are described in detail below by combination with accompanying drawings, but the present invention can be implemented by multiple different modes limited and covered by the claims.

As shown in FIG. 1 to FIG. 8, an efficient heat-storing energy-saving device provided by the present invention can be implemented according to the following embodiment: the device comprises a box body 1, a heat storage box 2, air pipes 3 and an inserted fan 4. The left side and the right side of the front of the box body 1 each are provided with one air pipe 3. At least one of the two air pipes 3 is connected with the inserted fan 4, and each air pipe 3 is provided with a control damper 12; heat insulation layers are disposed at different orientations of the inner side of the box body 1, and the heat insulation layers each comprise heat insulation cotton A7, heat insulation cotton B8, heat insulation cotton C9 and bottom heat insulation cotton 11 ; a base 6 for supporting is arranged below the bottom heat insulation cotton 11, inner boxes 10 are arranged in the heat insulation layers, and middle heat storage boxes 2 are fixed to the inner boxes 10.

Steel wires 14 are arranged in the heat storage boxes 2, aluminum oxide heat storage balls 13 are evenly arranged on the steel wires 14, the outer surfaces of the whole heat storage boxes 2 are covered with heat storage box casings 5, extended parts are positioned at the two ends of the heat storage box casings 5 respectively, and after the heat storage boxes are placed in the inner boxes, S-shaped air channels are formed in the box body.

The efficient heat-storing energy-saving device provided by the present invention has the working principle as follows: 1. Hot air passes the inserted fan 4 and enters the box body and is discharged through air pipes 3 on the opposite sides. The heat insulation box is around the box body, and it is ensured only a very small part of thermal energy in the box is lost. 2. During a heat storage stage, the inserted fan 4 connected with the air pipes 3 rotates forward, the hot air passes through the inserted fan 4 and enters the box body and is in full contact with the aluminum oxide heat storage balls 13, heat is absorbed by the aluminum oxide heat storage balls 13, and cold air is discharged out of an exhaust pipe. During a heat release stage, the air pipes are connected, the inserted fan 4 rotates reversely, the cold air passes through the air pipes and enters the box body, and when passing across the aluminum oxide heat storage balls having stored heat, the cold air takes away thermal energy on the aluminum oxide heat storage balls, so that the cold air is changed into hot air and the hot air is discharged out of the exhaust pipe. 3. The device may be only provided with one fan, the wind direction is changed by controlling the forward and reverse rotation of the fan to meet the ventilation requirements of the heat storage balls during heat storage and heat release. The box body is small in size and small in occupied area; and the S-shaped channels composed of the internal heat storage boxes can prolong the time of air passing through the box body, to make the air come into full contact with the heat storage balls.

During operation, when hot air passes across the heat storage balls, numerous small balls divide the air flow into very small streams; when the air flows in a heat storage body, strong turbulence is formed, and thus a boundary layer on the surface of the heat storage body is effectively broken through; besides, the balls are very small in ball diameter, small in conduction radius and thermal resistance, high in density and good in heat conductivity, and thus thermal energy in the hot air is timely absorbed. When cold air passes across the heat storage balls having stored heat well, the cold air will take away thermal energy inside the heat storage balls.
