The full-sealing anti-freezing and water-proof thermal insulating flat type solar thermal collector comprises a frame body, a baseboard, a thermal insulating mechanism, a lighting and transmitting mechanism and a heat absorbing mechanism, wherein the frame body is formed by matching of a pair of longitudinal frames and a pair of transverse frames, the baseboard is arranged on the lower portion of the frame body, the thermal insulating mechanism is arranged on the baseboard, the lighting and transmitting mechanism is positioned on the upper portion of the frame body, a heat absorbing cavity is formed between the lighting and transmitting mechanism and the thermal insulating mechanism, and the heat absorbing mechanism is arranged inside the heat absorbing cavity. The full-sealing anti-freezing and water-proof thermal insulating flat type solar thermal collector is characterized by further comprising a reinforcing heat absorbing mechanism and a gas discharging and pressure stabilizing mechanism, and the reinforcing heat absorbing mechanism is arranged inside the heat absorbing cavity. The heat absorbing cavity is divided into a pressure stabilizing cavity and a heat absorbing water pipe cavity by the reinforcing heat absorbing mechanism. The gas discharging and pressure stabilizing mechanism is arranged on one of the longitudinal frames or the transverse frames. The heat absorbing mechanism is arranged inside the heat absorbing water pipe cavity. The lighting and transmitting mechanism comprises an upper glass plate, a lower glass plate, a glass plate supporting frame, and a glass plate boundary sealing strip. The heat absorbing effect of the heat absorbing mechanism is guaranteed, assembling is convenient, the cost is saved, the heat absorbing effect and the integral heat collecting efficiency are improved, the pressure of the pressure stabilizing cavity is gradually constant with the outside, and the fragmentation of the upper glass plate and / or the lower glass plate is avoided.

Description

technical field [0001] The invention belongs to the technical field of water heating facilities, and in particular relates to a fully sealed antifreeze, waterproof and heat-preserving flat-plate solar heat collector. Background technique [0002] As people's awareness of energy conservation and environmental protection, as well as their awareness of protecting non-renewable natural resources such as oil, coal, and natural gas, continues to increase, the application of solar water heaters has gradually become popular. Most of the solar water heaters in the prior art use the structural form of vacuum tubes (also known as light-to-heat conversion glass tubes), and solar water heaters of this structural form can be seen in large numbers in Chinese patent documents, such as those recommended by CN1027661C for example. Antifreeze solar water heater, all-plastic integrated solar water heater introduced by CN1399110A, covered anti-hail solar water heater provided by CN2879040Y, hai...

Problems solved by technology

[0005] But the technical scheme that aforementioned CN102721189B proposes still has the following shortcoming: one, because the temperature of the heat-absorbing chamber between the glass plate that is formed in the structural system that belongs to daylighting light-transmitting mechanism and heat-insulating body namely heat-insulating mechanism has inevitable temperature difference, Especially in the heat absorption process of the heat-absorbing pipe which belongs to the structural system of the heat-absorbing mechanism arranged in the heat-absorbing chamber, the temperature difference between the heat-absorbing chamber and the outside is more significant, so condensation is easy to appear on the glass plate, It affects the heat absorption effect of the heat absorption pipe, and affects the heat collection efficiency of the collector; secondly, because the glass plate is a single-layer glass structure, it is necessary to match the glass plate with the frame through a sealing strip with a relatively complicated cross-sectional shape Sealing around the edges of the heat absorbing cavity is not only cumbersome to operate but also high in manufacturing cost. For details, please refer to paragraph 0027 of the specification of this patent; thirdly, in the actual use process, the following undesirable but Unavoidable situation: the pressure in the heat-absorbing chamber is out of balance with the external pressure, that is, the pressure in the heat-absorbing chamber is greater than the external pressure, so the glass will burst; As an auxiliary measure of thermal efficiency, the heat collection effect of a complete set of flat-plate solar collectors is difficult to meet the expectations of the industry
