A kind of solar energy light absorption thermal-arrest plate of the present utility model is achieved through the following technical solutions:

A kind of solar energy light absorption thermal-arrest plate, comprise warming plate and be fixed on support on the warming plate, with " it " font structure the metal heat-conducting pipe is set on the described support, on described metal heat-conducting pipe outer wall length direction, several metal fins are set at interval, hot water outlet is established on right side, described metal heat-conducting pipe upper end, cooling water inlet is established on right side, described metal heat-conducting pipe lower end, metal fin is squeezed or canoe is arranged on metal heat-conducting pipe periphery to overlap, guarantee that metal fin fully contacts with the metal heat-conducting pipe, be equipped with the hole that to pass the metal heat-conducting pipe on the biside plate of support.

Be arranged on the condenser groove that is spaced apart between each metal fin of described metal heat-conducting pipe outer wall, solar light irradiation reflects repeatedly by metal fin in condenser groove, on warming plate.

The metal heat-conducting pipe of " it " font structure on the described support can be replaced by the metal heat-conducting pipe that parallel longitudinal is provided with, " it " font metal heat-conducting pipe helps current, simultaneously, rack-mount metal heat-conducting pipe also can be about (promptly vertical) be arranged in parallel, it also can be alternate manner, several metal fins are set with laterally being arranged in parallel on the metal heat-conducting pipe of described parallel longitudinal setting at interval, be spaced apart condenser groove between described each metal fin, the plane of metal fin is vertical with the length direction of metal heat-conducting pipe. when the metal heat-conducting pipe is that parallel longitudinal is when being arranged on the support, metal fin is a plurality of rectangular pieces, and the length direction of whole metal heat-conducting Guan Bingyu metal heat-conducting pipes that the metal fin of each rectangular pieces runs through vertical setting is vertical.

A kind of solar energy light absorption thermal-arrest plate of the present utility model has following beneficial effect with respect to prior art:

1, the metal fin of a kind of solar energy light absorption thermal-arrest plate of the present utility model is provided with at interval along the length direction of metal heat-conducting pipe, form a condenser groove between each metal fin, solar light irradiation in condenser groove through the refraction repeatedly of metal fin, up to warming plate, can repeatedly utilize solar energy, make the utilization rate of sunshine reach 99%;

2, a kind of solar energy light absorption thermal-arrest plate of the present utility model when sunshine throws, when being refracted to warming plate, can improve the temperature of thermal-arrest backboard face from condenser groove, is heated evenly heated body;

3, a kind of solar energy light absorption thermal-arrest plate structure of the present utility model is simple, easy for installation, with low cost, effect is obvious.

The specific embodiment

For can knowing, the affiliated technical staff who makes this area understands the technical solution of the utility model, the further detailed explanation of existing do in conjunction with the accompanying drawings:

A kind of solar energy light absorption thermal-arrest plate, as shown in Figures 1 and 2, comprise warming plate 6 and be fixed on support 1 on the warming plate 6, with " it " font structure metal heat-conducting pipe 3 is set on the support 1, on metal heat-conducting pipe 3 outer wall length directions, several metal fins 2 are set at interval, hot water outlet 4 is established on right side, metal heat-conducting pipe 3 upper end, and cooling water inlet 5 is established on right side, metal heat-conducting pipe 3 lower end.

Be spaced apart condenser groove 7 between each metal fin 2, as shown in Figure 2.

The metal heat-conducting pipe 3 of " it " font structure on the support 1 can be replaced by the metal heat-conducting pipe 3 that parallel longitudinal is provided with, several metal fins 2 are set with laterally being arranged in parallel on the metal heat-conducting pipe 3 of parallel longitudinal setting at interval, be spaced apart condenser groove 7 between each metal fin 2, as shown in Figure 3.

Embodiment

At first adopt metal tube (have certain toughness as aluminium-alloy pipe etc.) with specific purpose tool be made into as shown in Figure 2 " it " font or the metal heat-conducting pipe 3 of structure parallel to each other, and metal heat-conducting pipe 3 penetrated in the hole on the support 1, crowded to overlap then, modes such as winding are horizontally installed on metal heat-conducting pipe 3 peripheries with metal fin 2, guarantee that metal fin 2 fully contacts with metal heat-conducting pipe 3, stay the condenser groove 7 of 1-2mm between each metal conducting strip 2, at metal heat-conducting pipe 3 one ends a hot water outlet 4 is set, the other end is provided with a cooling water inlet 5, promptly be made into solar energy light absorption thermal-arrest plate this moment. solar energy light absorption thermal-arrest plate is installed in the heat collector (not shown) of solar water heater, with set bolt support 1 is fixed in the heat collector, again cooling water inlet 5 is connected from the beginning on the water source by water pipe, simultaneously, hot water outlet 4 is connected watering equipment (as shower nozzle by water pipe, tap) on, again with glass cover also sealing on heat collector. during use, when sunlight is radiated on the metal fin 2 through glass, sunshine is refraction repeatedly in condenser groove 7, up to warming plate 6, can play the effect that solar energy is repeatedly utilized, can make the utilization rate of sunshine reach 99% level, because the metal fin in the utility model is laterally socket on the metal heat-conducting pipe, sunlight can project from condenser groove 7 on the warming plate 6, warming plate 6 be arranged on support 1 below, when sunshine throws from condenser groove 7, when being refracted on the warming plate 7, can improve the temperature of thermal-arrest backboard face, heated body is heated evenly. after cold water is in cooling water inlet 5 enters into metal heat-conducting pipe 3, because the irradiation of the sun, make metal fin 2 fully absorb the heat of the sun, and by the 3 conduction feedwater of metal heat-conducting pipe, feedwater is heated, water after heating is promptly discharged for people to use from hot water outlet 4. and the utility model not only is confined to the foregoing description, every in any conspicuous change of under the prerequisite of the utility model thought, being done, all will constitute infringement to the utility model patent.
