[0020] FIG. 1 is a structural schematic view of the dry floor heating module for building energy-saving and heat preservation, which comprises an upper cushion layer 10, a lower cushion layer 20, a reinforcing frame 30 and a phase change layer 40. Figures 1 to 3

[0021] ​In the embodiment, the upper cushion layer 10 can be made of heat-conducting silica gel pad material, and the top of the upper cushion layer 10 is formed with a floor heating pipe groove 11, and the bottom of the upper cushion layer 10 is formed with an upper clamping groove 12. The floor heating pipe groove 11 can be used for laying the floor heating pipe, and the upper clamping groove 12 can be used for positioning and installing the reinforcing frame 30. In addition, the heat-conducting silica gel material used by the upper cushion layer 10 is synthesized by adding certain metal oxides and various heat-conducting auxiliary materials based on silica gel, which can transfer the heat at the heating part, i.e. the floor heating pipe, to the phase change layer 40.

[0022] In the embodiment, the lower cushion layer 20 can be made of polystyrene or polyurethane extrusion processing. The top of the lower cushion layer 20 is formed with a lower clamping groove 21. The lower clamping groove 21 is also used for positioning and installing the reinforcing frame 30, i.e. the reinforcing frame 30 is embedded between the upper cushion layer 10 and the lower cushion layer 20 through the upper clamping groove 12 and the lower clamping groove 21, and the reinforcing frame 30 is fixed by adhesive between the upper cushion layer 10 and the lower cushion layer 20. The polystyrene or polyurethane extrusion pad forms a closed cell structure through a foaming process, air is trapped in the tiny pores, significantly reducing heat conduction, and the polymer matrix forms a continuous solid barrier, which can reduce the heat conduction path, thereby achieving the heat insulation function and reducing the heat transfer outward.

[0023] In the embodiment, the outer side walls of the lower cushion layer 20 and the upper cushion layer 10 and the bottom of the lower cushion layer 20 can also be coated with an aluminum foil reflective layer, which reflects the heat radiation back to the heat source side, further reducing the radiation heat transfer.

[0024] In the embodiment, the reinforcing frame 30 can be made of polycarbonate or polyamide plastic injection molding. The reinforcing frame 30 includes an outer frame 31, a plurality of annular frames 32, and a plurality of reinforcing ribs 33. The plurality of annular frames 32 are arranged at intervals on the inner side of the outer frame 31, and the reinforcing ribs 33 are formed between adjacent annular frames 32 and between the annular frames 32 and the adjacent inner walls of the outer frame 31. The reinforcing frame 30 is embedded between the lower cushion layer 20 and the upper cushion layer 10 to improve the compression and bending resistance of the dry floor heating module and reduce deformation damage.

[0025] In the embodiment, the phase change layer 40 fills the plurality of annular frames 32 arranged in the reinforcing frame 30, the phase change layer 40 can be made of a solid formed organic phase change material filling layer in the prior art, and the dry floor heating module can store heat by using the phase change layer 40 when the temperature of the floor heating pipe is high, and release heat by using the phase change layer 40 when the temperature of the floor heating pipe is low, so as to improve the use effect of the floor heating and reduce temperature fluctuation. The material used by the phase change layer 40 can refer to the phase change latent heat environment-friendly energy-saving building material and the preparation method thereof disclosed in the patent with the patent number CN105000840B. An organic phase change material is given in the patent, and the composition components can include the following components with the weight fraction: cement 50-80 parts, diatomite 30-50 parts, acetyl citric acid tributyl ester 0.5-3.5 parts, aliphatic water reducing agent 1-5 parts, poly-2,6-naphthalene diacid ethylene glycol ester fiber 10-15 parts, expanded vermiculite 2-7 parts, triethylene glycol monomethyl ether 30-50 parts, sebacic acid 8-15 parts, tetradecanoic acid 5-10 parts, and n-hexadecane 12-20 parts. By adding expanded vermiculite, triethylene glycol monomethyl ether, sebacic acid, tetradecanoic acid, and n-hexadecane in the preparation process, the material has the characteristics of good thermal conductivity and good fixed molding, and the thermal conductivity is 0.35-0.7 W / (m.K), the phase change temperature range is 15-30℃, and the phase change latent heat value is 40-90 J / g.
