Full-sealed efficient panel type solar heat collector

Abstract

The invention discloses a full-sealed efficient panel type solar heat collector. The full-sealed efficient panel type solar heat collector comprises a left frame and a right frame. A glass covering plate and a back plate are fixed between the left frame and the right frame. A left aluminum strip partition plate and a right aluminum strip partition plate are fixed on the lower surface of the glass covering plate, a baffle is fixed on the left aluminum strip partition plate and the right aluminum strip partition plate, and a cavity is formed by the baffle, the left aluminum strip partition plate, the right aluminum strip partition plate and the glass covering plate. A heat absorbing plate core fixedly connected with a copper tube is located inside the cavity, the left end and the right end of the heat absorbing plate core are fixedly connected with the left aluminum strip partition plate and the right aluminum strip partition plate, and the cavity is filled with inert gases. The full-sealed efficient panel type solar heat collector overcomes the defects of a traditional panel type solar heat collector, a full-sealed structure is adopted, the cavity formed by the baffle, the left aluminum strip partition plate, the right aluminum strip partition plate and the glass covering plate is filled with the inert gases, the heat loss produced when heat absorbing bodies pass through the glass covering plate is greatly reduced, and the heat absorbing bodies can be prevented from being affected by the atmospheric environment.

Description

Technical field: [0001] The invention relates to a solar heat collector, in particular to a flat-plate solar heat collector. Background technique: [0002] With the depletion of fossil energy, the resulting energy crisis has seriously jeopardized the normal order of economic development in the world, and the resulting energy and environmental problems have become increasingly prominent. It is an inevitable trend of world energy development in the 21st century. [0003] The solar collector is the heat-collecting and absorbing element of the solar system and the core of the solar system. Due to the constraints of the structural design and production process of the traditional flat-plate collector, its heat-collecting plate core, transparent cover, aluminum alloy It is impossible to achieve a complete seal between the frame and the back panel, resulting in the following deficiencies: 1) The dew condensation inside the glass affects the light transmittance, which in turn affect...

[0003] The solar collector is the heat-collecting and absorbing element of the solar system and the core of the solar system. Due to the constraints of the structural design and production process of the traditional flat-plate collector, its heat-collecting plate core, transparent cover, aluminum alloy It is impossible to achieve a complete seal between the frame and the back panel, resulting in the following deficiencies: 1) The dew condensation inside the glass affects the light transmittance, which in turn affects the conversion of solar energy; 2) The dew condensation on the surface of the heat-absorbing plate core, The heat-absorbing coating on the heat-absorbing plate core will be corroded and peeled off, reducing the working efficiency of the collector; 3) Dust and air pollutants will adhere to the outer surface of the heat-absorbing plate core and the inner surface of the transparent glass cover, causing The heat absorption efficiency of the collector decreases; 4) Since it cannot be completely sealed, the air convection inside and outside the collector is inevitable, which greatly increases the heat loss rate of the collector
