Abstract
The invention discloses a heater of geothermal heating system, which comprises a thermal-insulated waterproof layer and a cement concrete layer. Wherein, said cement concrete layer has an air tube. The invention arranges an air tube in the concrete layer, therefore, it has the advantages as uniform ground temperature, better heating effect, lower cost, high safety and energy-saving property.
Description
Technical field
The present invention relates to a kind of underground heat heating technology, especially a kind ofly radiation heating system.
Background technology
Adopt the hot-water heating technology of pre-buried water pipe or the electricity heating technology of pre-buried cable mostly in the technical field of underground heat heating at present, the way of taking is that water pipe or cable are embedded in the cement concrete layer of cement concrete, restriction because of the heat conductivility of cement concrete, so the mid portion heat of water pipe spacing or cable spacing is supplied with very little, temperature increase is too little, cause surface temperature inequality entirely, the underground heat poor effect, national sector standard has been stipulated the maximum laying spacing of water pipe or cable for this reason, even so, still there is the problem of surface temperature inequality in the underground heat of prior art, and the density of water pipe or cable is excessive, and cost has also strengthened.
Can not cover heat insulation article on the ground of cable laying in addition, hot-spot can occur like this, cause cable to burn out or the breaking out of fire accident.
Summary of the invention
Technical problem to be solved by this invention is, overcomes above-mentioned deficiency of the prior art, and the ground that a kind of cost is low, the thermal efficiency is high, surface temperature is even, safe and reliable radiation heating system is provided.
Be the technical problem of the existing ground radiation heating system that solves, a kind of ground of the present invention radiation heating system heater, adiabatic damp-proof layer, cement concrete layer are provided with air flow duct in the described cement concrete layer.
System of the present invention is owing to be provided with air flow duct in concrete layer, thereby advantage compared with prior art has following several respects:
1, surface temperature is even, and underground heat is effective;
2, energy-saving safe;
3, with low cost.
Description of drawings
Fig. 1 is the plan structure schematic diagram of first kind of embodiment of a kind of ground of the present invention radiation heating system;
Fig. 2 is the front view of system shown in Figure 1;
Fig. 3 is the structural representation of second kind of embodiment of a kind of ground of the present invention radiation heating system.
The specific embodiment
Embodiment one: as shown in Figure 1, 2, a kind of ground of the present invention radiation heating system comprises heater 1, adiabatic damp-proof layer 2, cement concrete layer 3, in the described cement concrete layer 3 air flow duct 4 is set.
The heater 1 of present embodiment is arranged in the air flow duct 4.Air flow duct 4 is the multistage pipeline, at the geothermal system scene of making each segment pipe is connected, and interface between each section and port seal with cement concrete 3.
In order to improve the effect that air flows, the air flow duct that present embodiment is designed to air flow duct 4 to be communicated with in length and breadth, like this hot-air in pipeline 4, flow more smooth and easy, the air flow duct 4 of present embodiment laterally, spacing between pipes design longitudinally be the best at 50mm to 500mm.
Present embodiment has been selected the making material of Heat Conduction Material as air flow duct 4 for use, scatters and disappears near heater 1 too much for avoiding heat, so the part is provided with heat-barrier material 5 near the air flow duct the heater 14, to guarantee that surface temperature is even; If select for use the material of certain effect of heat insulation to make air flow duct, just not be used in that the part has been provided with heat-barrier material 5 on air flow duct 4.
Concrete working method is: heater can be water pipe and cable, when heater 1 work, near the heater 1 air at first is heated, because whole air flow duct 1 is in sealing state substantially, hot-air can form convection current by cold air rapid and away from heater 1 in air flow duct 4, cross-ventilation speed will substantially exceed the conduction of velocity of hot-air and cement concrete layer 3, the equilibrium of realization surface temperature, heat-barrier material 5 is set keeps near the air high temperature of heater, convection effects can be better, cover when adiabatic or heat insulation article are arranged at heater 1 top, near the hot-air the heater 1 can flow to the low place of other temperature rapidly in air flow duct 4.
Embodiment two: as shown in Figure 3, the air flow duct 4 of present embodiment is provided with air intake 8, air outlet slit 9, heater 1 is arranged on outside the air flow duct 4, heater 1 outer setting air heats pipeline 6, heat air forced circulation device 7 is set in the pipeline 6, the air intake 8 of air flow duct 4, air outlet slit 9 connect outlet 11, the inlet 10 that air heats pipeline respectively, and described air heats pipeline 6, air flow duct 4 forms closed conduit.Described air forced circulation device 7 can guarantee the device of air circulation for fan or air pump etc., when heater 1 work, the air that air forced circulation device 7 will be heated by heater 1 through air heat the outlet 11 of pipeline 6, the inlet Final 8 system of air flow duct enters in the air flow duct 4, after enter air through the outlet 9 of air flow duct, inlet 10 circulations that air heats pipeline and heat in the pipeline 6 and heat once more by heater 1, finish once and circulate; The speed that hot-air flows in air flow duct 4 will substantially exceed the conduction of velocity of hot-air and cement, realize the surface temperature equilibrium.
Present embodiment is provided with heat insulation layer 12 outside air heats pipeline 6.
