Background
The geothermal heating is called low-temperature floor radiation heating for short, floor heating for short, and is a heating mode that hot water with the temperature not higher than 60 ℃ is used as a heating medium and circularly flows in a temperature adjusting pipe to heat the ground, and the ground supplies heat to the indoor in a radiation and convection conduction mode. Compared with an overground radiator set adopting a convection heat transfer mode for heat supply, the geothermal heating has the characteristics of high comfort level, energy conservation and small occupied indoor space, and therefore, the geothermal heating has wide development and application prospects.
Geothermal heating needs to lay ground heating installation in the below ground, and wherein, ground heating installation generally includes heat insulating board, the pipe and the heat-conducting layer of adjusting the temperature, as shown in fig. 1, has seted up mounting groove 11 on the heat insulating board, and the pipe that adjusts the temperature sets up in mounting groove 11, and the heat-conducting layer setting is seted up the one side of mounting groove 11 on the heat insulating board, and the heat-conducting layer contacts with the pipe that adjusts the temperature, and the pipe that adjusts the temperature leads the heat to ground.
The general temperature-adjusting pipe needs to be laid in a heat-insulating plate in a winding manner, and accordingly, as shown in fig. 1, a winding mounting groove 11 matched with the shape of the temperature-adjusting pipe is formed on the heat-insulating plate. Traditional heat-conducting layer is metal foil or non-metal foil, and general heat-conducting layer tiling is seted up mounting groove 11 at the heat insulating board on the surface, and the heat-conducting layer only contacts with the global top of the pipe that adjusts the temperature, and area of contact is less, and the space that exists between the pipe and the heat-conducting layer that adjust the temperature is too big, leads to adjusting the temperature to lead to heat transfer efficiency between pipe and the heat-conducting layer lower, and then leads to floor heating device heat conduction efficiency.
Therefore, there is a need for a floor heating apparatus that solves the above problems.

An embodiment of the utility model provides a floor heating device, as shown in fig. 2, this floor heating device includes heat insulating board 1, temperature adjusting pipe 2 and heat-conducting layer 3. Wherein, the heat insulating board 1 is used for the separation to adjust the temperature the heat of pipe 2 and to the below ground transmission, the mounting groove 11 has been seted up on the heat insulating board 1, adjust the temperature pipe 2 and set up in mounting groove 11, heat-conducting layer 3 includes first heat-conducting layer 31 and second heat-conducting layer 32, first heat-conducting layer 31 sets up on the heat insulating board 1 sets up the mounting groove 11 on the surface (this surface includes the internal surface of mounting groove 11), second heat-conducting layer 32 sets up on first heat-conducting layer 31 and adjust the temperature pipe 2, and second heat-conducting layer 32 and first heat-conducting layer 31 wrap up adjust the temperature.
Because first heat-conducting layer 31 and second heat-conducting layer 32 wrap temperature adjusting pipe 2 jointly completely, increased the area of contact between heat-conducting layer 3 and the temperature adjusting pipe 2 to improve the heat transfer efficiency between heat-conducting layer 3 and the temperature adjusting pipe 2, the part of heat-conducting layer 3 that contacts with temperature adjusting pipe 2 can be fast evenly with the heat conduction to whole heat-conducting layer 3 that the temperature adjusting pipe 2 gived off, and then make floor heating device have higher heat conduction efficiency.
Specifically, the mounting groove 11 is formed in the upper surface of the heat insulation plate 1, the opening of the mounting groove 11 is upward, and the heat insulation plate 1 has the effect of blocking heat, so that the heat emitted downwards by the heat conduction layer 3 is blocked by the heat insulation plate 1, the heat conduction layer 3 is prevented from transmitting part of heat to the ground below to cause heat loss of the part of heat, and the heat of the heat conduction layer 3 can be transmitted only along the heat conduction layer 3 and to the upper side of the heat conduction layer 3. It should be noted that the heat insulation board 1 may be a polystyrene foam board, or may be a plate made of other materials, as long as the heat insulation board 1 can prevent heat from being transferred to the ground.
In addition, in order to further obstruct the heat from transferring to the ground surface and improve the utilization efficiency of the floor heating device to the heat emitted by the temperature adjusting pipe 2, the floor heating device further comprises a reflecting film (not shown in fig. 2). The reflective film is laid on the surface of the heat insulation board 1 provided with the mounting groove 11, the reflective film is located between the first heat conduction layer 31 and the heat insulation board 1, and the reflective film is used for reflecting heat. Most of heat that heat-conducting layer 3 gived off downwards can receive the reflection of reflectance coating and upwards transmit, has avoided the thermal loss of this part, has improved floor heating device's heat utilization ratio. The reflective film may be a bubble mat aluminized reflective film or a specular reflective film, and is not limited herein.
Preferably the thickness of the first layer 31 is in the range 0.5mm to 1mm, preferably 0.8 mm. If the thickness of the first heat conduction layer 31 is larger than 1mm, the heat conduction time is increased, and the heat conduction efficiency of the floor heating device is reduced; if the thickness of the first heat conduction layer 31 is smaller than 0.5mm, the processing difficulty of the first heat conduction layer 31 is increased, the processed first heat conduction layer 31 is easily discontinuous, the defective rate is increased, and the production cost of the floor heating device is increased.
Further, the thickness of the second layer 32 above the first layer 31 is in the range of 0.5mm to 1mm, preferably 0.8 mm. If the thickness of this part second heat-conducting layer 32 is greater than 1mm, can increase the heat conduction time, cause floor heating device heat conduction efficiency to reduce. If the thickness of the second heat conduction layer 32 is smaller than 0.5mm, the processed second heat conduction layer 32 is easily discontinuous, the defective rate is increased, and the production cost of the floor heating device is increased.
Note that, in order to allow the heat conductive layer 3 to conduct heat quickly, the heat conductivity of the first heat conductive layer 31 is not less than 35W/(m × K), and the heat conductivity of the second heat conductive layer 32 is not less than 35W/(m × K).
In addition, the floor heating device also comprises a soaking plate 4. The lower surface of the soaking plate 4 is in contact with the upper surface of the second heat conductive layer 32. Through setting up soaking board 4 in second heat-conducting layer 32 top, avoided making heat-conducting layer 3 receive the extrusion because of floor heating device receives the extrusion or strikes, lead to the degree of consistency of heat-conducting layer 3 to be destroyed, also avoided simultaneously that temperature adjusting pipe 2 receives the extrusion or strikes and take place to damage, guarantee that heat-conducting layer 3 conducts to the heat of soaking board 4 more even of transmission on soaking board 4 for floor heating device dispels the heat more evenly.
In order to ensure good compression resistance of the soaking plate, the compression strength of the soaking plate 4 is not lower than 100 kPa. Specifically, the soaking plate 4 may be a aventurine plate, a calcium silicate plate, a fiber plate, or a gypsum plate, and is not limited thereto.
In order to uniformly conduct the heat of the second heat conduction layer 32 to the soaking plate 4, the surface of the second heat conduction layer 32 contacting with the soaking plate 4 is a plane.
The heat transfer process of the floor heating device in this embodiment is as follows:
the heat that the pipe 2 gived off adjusts the temperature conducts to the heat-conducting layer 3 with the part that adjusts the temperature pipe 2 and contact, then the heat-conducting layer 3 with the part that adjusts the temperature pipe 2 and contact with the heat conduct heat to whole heat-conducting layer 3 fast evenly, heat-conducting layer 3 with heat conduction to soaking plate 4, the heat evenly spreads then conduction to ground on soaking plate 4.
