Abstract
The utility model discloses a flat plate type solar collector, which comprises a chassis, an upper laminated frame and transparent plates. The transparent plates are arranged between the upper laminated frame and the chassis, the transparent plates are compressed tightly and fixed by the upper laminated frame and the chassis press; the chassis and a step vertically extending from the upper laminated frame form a horizontal sealing groove, sealing bars on the two horizontal sides of the transparent plates are arranged in the horizontal sealing groove, a support bar extending horizontally is arranged in the chassis, the upper laminated frame and the support bar form a vertical sealing groove, and rubber sealing bars on the two vertical sides of the transparent plates are arranged in the vertical sealing groove. Since the collector plate consists of a plurality of transparent plates, and the transparent plates are pressed by the upper laminated frame and the chassis, the collector plate has high bearing capacity. Moreover, the groove which is arranged in the chassis can reinforce the chassis in a shallow dish shape, thereby further enhancing the bearing performance of the collector.
Description
Technical field
The utility model relates to a kind of solar thermal collector, is specifically related to a kind of flat-plate solar heat collector.
Background technology
The inventor is in Chinese invention patent specification CN101498512A (January 15 2009 applying date; open day on August 5th, 2009) a kind of flat-plate solar heat collector is disclosed in; this flat-plate solar heat collector adopts the lower plywood and the upper panel driving fit of tray shape to form; and top plate adopts transparent plate; the sunlight direct irradiation is at the heat absorbing coating of transparent plate inner surface; heat absorbing coating is close to water simultaneously; so can amplitude peak ground the water in the heat transferred lower plywood that absorbs; black fish tail and waterproof layer and heat-insulation layer can be preserved the heat that water absorbed to greatest extent simultaneously, have reduced the heat waste rate.
But this flat-plate solar heat collector is in actual use, and there is certain hydraulic pressure in the water between lower plywood and the upper panel, and this hydraulic pressure can produce following influence to heat collector:
1, the area of the flat plate collector of standard is very big, is generally 2m
2/ piece is if adopt a 2m
2Glass as upper panel, this upper panel can't be born hydraulic pressure huge between lower plywood and the upper panel, very easily causes breaking of upper panel;
2, lower plywood adopts plastics to make, but the creep resistance of plastics is poor, and as the pressure bearing system of water layer between lower plywood and the upper panel, its pressure-bearing property is poor.
The utility model content
Technical problem to be solved in the utility model provides a kind of flat-plate solar heat collector, and it can solve the harmful effect problem of the interior hydraulic pressure of heat collector to heat collector.
For solving the problems of the technologies described above, the technical solution of the utility model flat-plate solar heat collector is:
Comprise chassis, upper strata press box, transparent panel; Transparent panel is arranged between upper strata press box and the chassis, and upper strata press box and chassis are fixed transparent panel; The step of the longitudinal extension of chassis and upper strata press box forms the transverse sealing groove, and the sealing strip on the horizontal both sides of transparent panel is arranged in the described transverse sealing groove.
Be provided with the support bar of horizontal expansion in the described chassis, form the longitudinal sealing groove between upper strata press box and the support bar, the rubber weather strip on the vertical both sides of transparent panel is arranged in the described longitudinal sealing groove.
The sealing strip that is provided with around the described transparent panel is a rubber weather strip.
The bottom on described chassis is provided with many grooves.
Described support bar is higher than the chassis.
The bottom surface or the end face of described transparent panel scribble selective heat absorbing coating.
Be dielectric liquid layer between described chassis and the upper panel, liquid medium is water, anti-icing fluid or silicone oil.
The technique effect that the utility model can reach is:
Thermal-arrest plate of the present utility model is made up of the polylith transparent panel, and transparent panel compresses jointly by upper strata press box and chassis, so the load performance of thermal-arrest plate is better.
Be provided with groove in the chassis of the present utility model, groove can play strengthening action to the chassis of tray shape, further strengthens the load performance of heat collector.
Metal material or the good engineering plastics of creep-resistant property are adopted in chassis of the present utility model, have strengthened the load performance of heat collector again.

Description of reference numerals among the figure:
10 is the chassis, and 11 is support bar, and 12 is groove,
13 is fluid path, and 21 is press box, and 22 is transparent panel,
23 is sealing strip, and 24 is heat absorbing coating.
The specific embodiment
As shown in Figures 1 to 4, the utility model flat-plate solar heat collector comprises chassis 10, upper strata press box 21, transparent panel 22; Transparent panel 22 is arranged between upper strata press box 21 and the chassis 10, and upper strata press box 21 is fixed transparent panel 22 with chassis 10.
Be provided with rubber weather strip 23 around the transparent panel 22; Chassis 10 and upper strata press box 21 are respectively equipped with the step of longitudinal extension, the step of the two matches, the cooperation place of the two forms the transverse sealing groove, the rubber weather strip 23 on transparent panel 22 horizontal both sides is arranged in the transverse sealing groove, and then the rubber weather strip 23 on transparent panel 22 horizontal both sides is compressed by upper strata press box 21 and chassis 10 and plays watertightness.Upper strata press box 21 is realized being connected with vertical combining form by screw, riveted joint, welding or several persons on chassis 10.
Be provided with the support bar 11 of horizontal expansion in the chassis 10, form the longitudinal sealing groove between upper strata press box 21 and the support bar 11, the rubber weather strip 23 on transparent panel 22 vertical both sides is arranged in the longitudinal sealing groove, and then the rubber weather strip 23 on transparent panel 22 vertical both sides is compressed by upper strata press box 21 and support bar 11 and plays watertightness.
The bottom surface of transparent panel 22 or end face scribble selective heat absorbing coating 24.
The bottom on chassis 10 is provided with many grooves 12, and the trend of groove 12 is consistent with the trend of fluid path 13.
The press box 21 of upper panel 20 is a metal material.
