Detailed description of the invention
As shown in Figure 1-Figure 3, one embodiment of the invention is two-layer is up and down metal sheet (as steel plate, copper coin, aluminium sheet etc.), and intermediate course vacuumizes rear filling working medium (as water, ethanol, ammonia, freon etc.).Fin is welded to strengthen its compressive strength between two metal sheets.
When underlaying surface temperature is higher than upper surface temperature time, refrigerant vapor is saturated vapor state, the boiling point of the temperature of saturated vapor and saturated vapor pressure working medium.Under this state, working medium can be seethed with excitement or rapid evaporation, the refrigerant vapor produced meets condensation knot at upper surface, when working medium condensation arrives certain thickness, because Action of Gravity Field can fall back again working medium layer, thus constantly move upward with heat at steam layer formation refrigerant vapor, form the caloic cyclic process that condensation working medium falls after rise after condensation heat.The boiling of working medium or rapid evaporation in metal sheet interlayer, and the caloic circulation of vacuum layer all belongs to phase-change heat transfer process, its thermal resistance is very little, so with this understanding, roofing entire thermal resistance is also very little, contributes to distributing of indoor heat.
And when temperature height than soffit of the temperature of upper surface, upper strata refrigerant vapor is superheated vapor, its pressure be greater than synthermal under saturated refrigerant vapor pressure, boiling point is higher than itself temperature at this pressure for working medium layer, and working medium surface will be in equilibrium state.Now because steam layer is the downward closed narrow space conduction model of hot plate, the steam layer of upper heat and lower cold is formed in interlayer, heat convection can not be carried out, and the inner surface of described metal sheet all scribbles aluminium paint, radiation heat transfer is weakened severely, so the thermal resistance of roofing is very large, effective heat-blocking action can be played.
Invention also provides a kind of preparation method of energy-saving roof module and internally ribbed overall package, the preparation method of described internally ribbed overall package comprises the following steps:
1), choose satisfactory metal material and carry out machining, metal material processing is become the roof covering metal plate two pieces of required size and fin some, described roof covering metal plate and fin thickness calculate according to roofing bearing requirements, at described fin while process semi-circular channel, semicircle radius is greater than the working medium layer thickness that will fill, or has aperture connection on described fin top;
2), to step 1) obtain described metal sheet and fin degreasing and rust removal, then use anti-rust cleaning agent cleaned up under clean environment;
3), to step 2) the described metal sheet that obtains and fin hot blast dry;
4), in the described metal sheet of step 3) acquisition, select one piece as metal sheet under roofing, weld fin thereon, fin has welding with it of semi-circular channel;
5) inner surface of described metal sheet that the metal sheet not welding fin, to step 3) obtained and step 4) obtain and fin brushing can reduce the coating of its slin emissivity, as aluminium paint etc.;
6), to step 5) obtain described metal sheet carry out end cap welding, described end cap stay one can for vacuumizing opening, double layer of metal plate forms a metal sheet interlayer;
7), to the described metal sheet interlayer vacuum-pumping that step 6) obtains;
8), working medium (as water, ethanol, ammonia, freon etc.) is filled to the described metal sheet interlayer that step 7) obtains, working medium layer (2) and refrigerant vapor layer (3) is formed in described metal sheet interlayer, as as described in working medium be water, then heating should be used before filling to remove the air be dissolved in wherein;
9), to the described metal sheet interlayer opening that step 8) obtains weld, form an integral roofing;
10), to the described roofing that step 9) obtains test, use leakage detector to check whether gas leakage, check that whether welding is tight, whether pad is smooth.
Energy-saving roof of the present invention is used in the communication base station of Changsha city, simulate its service condition, suppose that the length, width and height of a communication base station are of a size of 4m 4m 3m, equipment heating power is 3480W, body of wall is common brick mix structure, and for keeping interior temperature less than 28 DEG C, so during use ordinary concrete roofing, annual air conditioning energy consumption is 7700 degree of electricity, and annual air conditioning energy consumption is 5280 degree of electricity when using roofing of the present invention, energy-conservationly reach 31.4%.When outdoor combined air temperature is 20 DEG C, the heat dissipation capacity of ordinary concrete roofing is 6.8
