Dry-type paved geothermal floor board

Abstract

The invention relates to a dry-type paved geothermal floor board which belongs to the technical field of building decorative materials. The dry-type paved geothermal floor board comprises a substrate, wherein the upper surface of the substrate is provided with a decorative surface layer; the two sides of the substrate are provided with locks that can be matched with adjacent substrates respectively; an upward-concave groove is formed on the lower surface of the substrate; the groove comprises two side parts and an upper bottom part between the two side parts; a heat conducting medium layer is attached to the surface of the groove, and at least covers the upper bottom of the groove; a heat insulation module in contact with the ground is arranged below the substrate; an upward-protruding boss is formed on the upper surface of the heat insulation module; the shape of the boss is matched with the shape of the groove on the lower surface of the substrate; and a heating body in heat-conducting contact with the heat conducting medium layer is arranged between the heat insulation module and the heat conducting medium layer. The surface of the floor board is uniformly heated, the heat conducting path is relatively short, the heat efficiency is relatively high, and the entire pavement thickness is relatively small.

Description

technical field [0001] The invention relates to a dry paving geothermal floor, which belongs to the technical field of building decoration materials. Background technique [0002] In the prior art, the heat conduction medium or heating element of the geothermal floor is set separately from the floor, or laid on the ground or installed inside other components such as the bottom plate between the ground and the floor. For example, Chinese patent literature discloses a composite geothermal floor [application number: CN 200510040599.2], which solves the problems of low thermal conductivity, large deformation and easy cracking of the surface of the existing geothermal floor. It includes a surface plate, a sub-surface plate, a core plate, and a bottom plate. A horizontal heat conduction groove is arranged in the core plate, and a longitudinal heat conduction groove is arranged in the bottom plate. Filled with heat transfer medium. In the above technical solution, the heat conduc...
