Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.It should be noted that at this, the explanation for these embodiments understands the utility model for helping, but does not form restriction of the present utility model.
As shown in Figures 1 to 9, the utility model comprises plate body 1 and transparent cover plate 2, and described plate body 1 comprises top panel 11 and lower panel 12, and the cross section of described top panel 11 and lower panel 12 is waveform; Gap is had between described top panel 11 and lower panel 12, and top panel 11 and the sealing of lower panel 12 coincident; Described transparent cover plate 2 covers described top panel 11, and has gap between transparent cover plate 2 and top panel 11, and this gap is vacuum or partial vacuum state.
Its design principle is as follows: general solar absorber plate adopts vacuum tube or adds the structure of metal tube in flat panel backlight face, the former effective endotherm area is little, the heat of absorption is passed to metal tube by the heat absorption flat plate of the latter, metal tube transfers heat to water again, add intermediate heat link, thermal dissipation is many.Disclosed in the utility model, solar absorber plate plate body 1 adopts the structure of two-ply: top panel 11 seals with lower panel 12 and overlaps, and top panel 11 is absorber plate.Cold water is uniformly distributed wherein after entering plate body 1, and the even heat of absorption is directly passed to water in plate body 1 by top panel 11, and heat transfer efficiency is high.Because top panel 11 cross section is waveform, increase the endotherm area of top panel 11, thus add its caloric receptivity; In order to coordinate with top panel 11, lower panel 12 is also waveform; Top panel 11 and lower panel 12 coordinate the space being formed and hold water.The radiation of heat is absorbed in order to reduce top panel 11, top panel 11 covers transparent cover plate 2, the effect of transparent cover plate 2 is through visible ray and intercepts far infrared, such solar ray energy is irradiated on top panel 11 through transparent cover plate 2, but the infrared ray that top panel 11 raises radiation by temperature is then intercepted by transparent cover plate 2, make it outwardly not transmit, and then decrease scattering and disappearing of heat energy.
Specifically, as shown in Fig. 4, Fig. 5, Fig. 8 and Fig. 9, described top panel 11 is connected in the butt-joint of crest place with lower panel 12, and the trough of top panel 11 and lower panel 12 correspondence forms water storage groove, is evenly distributed in each bar water storage groove after cold water enters.
Specifically, top panel 11 and the welding of lower panel 12 peripheral sealing, this ensures that there the air-tightness of plate body 1, and water can not run off in the cavity that top panel 11 and lower panel 12 are formed.In order to increase the assimilation effect of top panel 11, coat heat-sink shell in its surface.Heat-sink shell can be but very low for the longwave transmissions rate shortwave radiation of sunshine to high-absorbility and residing temperature itself selective coating, also the non-selective coating equal with the longwave transmissions rate of residing temperature itself to the absorptivity of the shortwave radiation of sunshine can be selected, if be coated with non-selective coating, be generally coat thin and uniform Berlin black.
Specifically, in order to reduce scattering and disappearing of the heat of water in plate body 1 further, can add heat-insulation layer in plate 12 back below, the material of heat-insulation layer can select rock wool, mineral wool, polystyrene, polyurethane etc.Heat-insulation layer also need be suppressed the groove of barrier shape, make closely cooperating of its shape and lower panel 12.In order to enable solar absorber plate fix on the ground, welding bracing frame with angle steel, bracing frame being arranged on lower panel surrounding.
Specifically, the fixed form of transparent cover plate 2 on top panel 11 adopts fluid sealant 21 to fix.Fluid sealant 21 has and should not trickle and the good advantage of caking property.Specific practice is, coats fluid sealant 21 equably, be then bonded on fluid sealant 21 by transparent cover plate 2 in top panel 11 surrounding.Because fluid sealant 21 has certain thickness, after bonding transparent cover plate 2, gap can be formed between transparent cover plate 2 and top panel 11, and this gap space is very little, is beneficial to and vacuumizes; Next step, vacuumize process to this gap, becomes vacuum or partial vacuum state.The effect of insulation can be played in the gap of this vacuum or partial vacuum state.
Specifically, the Material selec-tion copper coin of top panel 11 and lower panel 12, aluminium alloy plate or steel plate.The material of transparent cover plate 2 can select high-strength temperature-resistant glass, MMA-methyl methacrylate plate, FRP-fiberglass reinforced plastics plate etc.
Specifically, the average height in the gap between top panel 11 and lower panel 12 is 0.4 ~ 1cm.
Concrete, the length of top panel 11 and lower panel 12 is 1.5m, and wide is 1m, and the average height in the gap between top panel 11 and lower panel 12 is 0.4cm.The shape of cross section of top panel 11 and lower panel 12 is trapezoidal flute profile, as shown in Figure 2 and Figure 3.The material of top panel 11 is copper, and the material of lower panel 12 is aluminium alloy, and the material of transparent cover plate 2 is high-strength temperature-resistant glass, and the material of heat-insulation layer is rock wool.
Concrete, the length of top panel 11 and lower panel 12 is 1.5m, and wide is 1m, and the average height in the gap between top panel 11 and lower panel 12 is 0.4cm.The shape of cross section of top panel 11 and lower panel 12 is waveform, as shown in Figure 4, Figure 5.The material of top panel 11 is copper, and the material of lower panel 12 is aluminium alloy, and the material of transparent cover plate 2 is high-strength temperature-resistant glass, and the material of heat-insulation layer is rock wool.
