Description

technical field [0001] The invention relates to the technical field of floor heating and heat transfer, in particular to a method for preparing a heat conducting layer and a floor heating device. Background technique [0002] The full name of geothermal heating is low-temperature floor radiation heating, referred to as floor heating. It uses hot water not higher than 60°C as the heating medium to circulate in the thermostat tube to heat the ground, and the ground then supplies heat to the room through radiation and convection conduction. heating method. Compared with the floor radiator group that adopts convective heat transfer to provide heat, geothermal heating has the characteristics of high comfort, energy saving, and small indoor space occupation, so it has broad development and application prospects. [0003] Geothermal heating needs to lay a floor heating device under the ground, where the floor heating device generally includes a heat insulation board, a thermostat ...

AI Technical Summary

Problems solved by technology

The traditional heat conduction layer is metal foil or non-metal foil. Generally, the heat conduction layer is laid flat on the surface of the heat insulation board provided with the installation groove 11. The heat conduction layer only contacts the top of the outer peripheral surface of the thermostat tube, and the contact area is small. The gap between the temperature tube and the heat conduction layer is too large, resulting in low heat transfer efficiency between the temperature control tube and the heat conduction layer

[0005] In order to improve the heat transfer efficiency between the floor heating device and the heat-conducting layer, in the prior art, the heat-conducting layer is often deformed by pressing the heat-conducting layer to increase the contact area between the heat-conducting layer and the temperature-regulating tube, thereby improving the temperature-regulating tube. The heat transfer efficiency between the heat conduction layer and the heat conduction layer, but since the thermostat tube includes straight pipe sections and curved pipe sections, the initial state of the metal foil or non-metal foil is flat, so the heat conduction layer and the bending are increased by pressing the heat conduction layer. The contact area between the pipe sections will cause the heat conduction layer to wrinkle, thereby reducing the heat transfer efficiency between the thermostat tube and the heat conduction layer, and because the metal foil and non-metal foil have poor resistance to deformation, the heat conduction layer may be damaged during the pressing process. Tearing occurs in the

[0006] In order to avoid wrinkles or tears in the heat-conducting layer, so that the heat-conducting layer can be attached to the curved pipe section of the thermostat tube, in the prior art, several incisions are generally cut in the transverse direction of the heat-conducting layer corresponding to the curved pipe section, so that the heat-conducting layer can be as close as possible Attached to the curved pipe section, but this method will reduce the heat conduction efficiency inside the heat conduction layer, making it difficult for the heat of the thermostat tube to conduct quickly and evenly to the entire heat conduction layer, thereby reducing the heat conduction efficiency of the floor heating device
