Embodiment 1

[0016] Such as figure 1 , figure 2 , image 3 As shown, a high-efficiency flat-plate heat collector includes a glass panel 1, a heat absorbing plate 6, an insulation layer 8 and a back plate 10, the glass panel 1 adopts cloth glass, and the gap between the glass panel 1 and the heat absorbing plate 6 The left and right ends of the cavity are equipped with straight-sided U-shaped aluminum alloy frames 2, the U-shaped opening of which faces the outside, and the opening is blocked by a thermal insulation sheet 4. The cavity of the aluminum alloy frame 2 is equipped with a desiccant 3, and the glass panel 1 is in contact with the heat absorber. The end side of the plate 6 is sealed by the rubber seal 5. The circulation liquid pipe 11 is fixedly connected to the bottom of the heat absorption plate 6. There is an insulation layer 8 and a back plate 10 under the circulation liquid pipe 11. The two ends of the back plate 10 are provided with composite The seal 9; the back plate 10 ...

Embodiment 2

[0020] The difference between this embodiment and the first embodiment is that nitrogen is used as the inert gas medium.

Abstract

The invention provides a high-efficiency flat-plate heat collector, which includes a glass panel, a heat-absorbing plate, an insulation layer and a back plate. The cavity between the glass panel and the heat-absorbing plate is filled with inert gas, and the front and rear ends of the cavity are respectively An air injection port and an exhaust port are provided, the air injection port is provided with a sealing protection cap, and the exhaust port is provided with a sealing part. The inert gas injection adopts a one-way passage structure, and the gas can only be injected in one direction. The inert gas is injected between the sealed glass panel and the heat collecting plate, because the activity of the inert gas is reduced, thereby reducing the heat dissipation of the heat collector itself, increasing the temperature of the surface of the heat collecting plate and the heat collection efficiency of the solar heat collector.

Description

technical field [0001] The invention relates to a heat collector and belongs to the field of solar energy devices. Background technique [0002] The flat-plate solar water heating system has the advantages of high efficiency, long life, good reliability, and the ability to integrate with buildings. However, in winter, due to the low ambient temperature and high heat loss caused by air convection inside the solar collector, As a result, the heat production in winter cannot meet the needs of use, the heat absorption efficiency of the collector is reduced, and the heat gain efficiency is very different in winter and summer. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a high-efficiency flat-plate heat collector, which can reduce the heat dissipation of the heat collector itself, improve the temperature of the surface of the heat collector plate and the heat collection efficiency ...
