One side of the sand storage box 602 exchanges heat with the reflective heat insulation box 502 through the first heat exchanging plate 610; the other side of that sand storage box 602 exchange heat with the heat exchanging component 7 through the second heat exchanging plate 609; the first heat exchanging plate 610 and the second heat exchanging plate 609 are fixedly connected to the side wall of the sand storage box 602; the sand storage box 602 is filled with fine sand.
The sand storage box 602 is fixedly connected to the surface of the soil 8 through legs 611.
Fine sand has the characteristics of storing heat and slow heat release period. The fine sand is heated by the sunlight in the first heat exchanging plate 610. In order to ensure the uniform heating of fine sand, the transmission shaft 604 is driven by the driving part to drive the packing auger 606 to rotate, so that the fine sand inside is lifted up and enters the cavity between the sand storage box 602 and the internal spacer annular plate 603 through the annular plate sand outlet 605 circumferentially opened on the top side wall of the internal spacer annular plate 603. In this cavity, the fine sand is heated by the first heat exchanging plate 610, and the heat is transferred to the water in the heat exchanging component 7 by the second heat exchanging plate 609.
Because the bottom of the sand storage box 602 is of an inverted frustum structure; fine sand will enter the internal spacer annular plate 603 through a plurality of annular plate sand inlets 612 on the bottom side wall of the internal spacer annular plate 603, and be lifted by the packing auger 606 again, and so on, sa that the fine sand in the sand storage box 602 is uniformly heated.
The driving part is preferably a motor 607, and the output shaft of the motor 607 is fixedly connected with one end of the transmission shaft 604.
In a further optimization scheme, the heat exchanging component 7 comprises a water tank 701; one side of the water tank 701 is arranged in heat exchanging with the second heat exchanging plate 809; the water tank 701 is fixedly connected to the outer side wall of the sand storage box 602; the water tank 701 is wrapped with a thermal insulation layer 702; the bottom of that water tank 701 is respectively communicated with the top of the first communicating pipe 9 and the second communicating pipe 10.
The water in the water tank 701 exchanges heat with the fine sand through the second heat exchanging plate 609. The thermal insulation layer 702 can prevent heat loss.
In a further optimization scheme, the heat exchanging plate 16 comprises a plate body 1601; the plate body 1601 is buried in the soil 8; the plate body 1601 is located below the frame body 2104; a continuous S-shaped bent coil pipe 1602 is arranged in the plate body 1601; one end of the coil pipe 1602 is communicated with the first water pumping part; the other end of the coil pipe 1602 communicates with the water storage tank 4 through a third communicating pipe 17.
The continuous S-shaped bent coil pipe 1602 increases the contact area with the soil 8, thereby improving the heat transfer efficiency.
Further optimized, the heat dissipation component 13 includes a radiating main pipe 1303; a plurality of radiating main pipes 1303 are uniformly arranged at the bottom of the underground thermal storage layer 14; one end of a plurality of radiating main pipes 1303 is communicated with the same second water pumping part; the other ends of a plurality of radiating main pipes 1303 are communicated with one end of the same fourth communicating pipe 18; the other end of the fourth communicating pipe 18 is communicated with the bottom of the water storage tank 4,
A plurality of vertically arranged radiating branch pipes 1301 are arranged on the radiating main pipe 1303; the radiating main pipe 1303 is communicated with the radiating branch pipe 1301; a plurality of radiating branch pipes 1301 are arranged at equal intervals along the length direction of the radiating main pipe 1303; the radiating branch pipe 1301 is circumferentially provided with radiating fork pipes 1302 arranged in a matrix; the radiating fork pipe 1302 communicates with the radiating branch pipe 1301.
A plurality of radiating fork pipes 1302 are arranged in a tree branch shape on the radiating branch pipe 1301; When water fills the radiating fork pipe 1302, the contact area with the heat storage medium inside the underground thermal storage layer 14 increases, effectively improving the heat transfer efficiency; the underground thermal storage layer 14 can use original sail or be filled with sand. Because the soil 8 itself can store a certain amount of heat, when water passes through the underground thermal storage layer 14, it can store a part of the heat, thus achieving the effect of energy storage and energy saving. Moreover, the heat in the underground thermal storage layer 14 can be prevented from dispersing upwards, which will affect the refrigeration effect of the soil 8 in summer.
The heat insulating part is preferably the thermal insulation plate 15.
