Problems solved by technology

Since there is only one layer of glass on the board core, the thermal insulation effect is poor, the temperature of hot water cannot be raised, and the thermal efficiency is low.
And because the insulation layer under the board core is thick and heavy, it cannot be better combined with the building

Embodiment Construction

[0009] The specific embodiment of the present invention is described below in conjunction with accompanying drawing, according to appended figure 1 In the shown shape, the copper tube is first bent into a bow-shaped curved tube with a vertical section and a horizontal section, and the heat exchange tube (4) is welded on the upper surface of the heat-absorbing plate (3) with the prior art to become a plate core; Then according to the shape of the core, make a mold; Utilize the mold to suppress the hot-melt glass into an upper half box (1) and a lower half box (2) with support columns (5); the core is placed on the lower half box (2) In the middle, the two ends of the heat exchange tube (4) protrude from the tube hole (7) to form a nozzle (8), and the nozzle and the tube hole are sealed with a sealant. There are 2 nozzles in total, which are used to connect the external pipeline. Then, apply glue on the fastening surface of the lower half box (2), fasten the upper half box (1),...

Abstract

The invention belongs to the field of application of solar energy, and discloses a curved tube type solar thermal collector. As only a transmitting glass layer for heat insulation is arranged on a plate core of an existing thermal collector of a solar water heater, heat-insulation performance is poor, temperature cannot be increased, and thermal efficiency is low. The curved tube type solar thermal collector is characterized in that a heat exchange tube (4) is bent into the curved tube and is adhered in a groove of the surface of an absorber plate to be used as the plate core, and the plate core is disposed in the middle of a full-glass vacuum box consisting of an upper half box (1) and a lower half box (2), so that a vacuum heat-insulation layer is formed between the plate core of the thermal collector and the glass box. The curved tube type solar thermal collector has the advantages that a vacuum heat-insulation effect is good, the working temperature of the thermal collector can be effectively increased, and thermal efficiency is improved; the plate core only consists of the curved tube and the plate, and the structure is simple; the curved tube is adhered with the absorber plate, so that labor and power are saved; cost can be greatly lowered; and the box is only provided with an upper glass layer and a lower glass layer, so that the thermal collector can be light and thin, is convenient to install and is integrated with a building more easily.

Description

technical field [0001] The invention belongs to the field of solar energy applications, in particular to solar flat water heaters. Background technique [0002] The heat collector used for solar flat water heaters consists of a box body and a plate core. In the prior art, an insulating material is arranged in a box body, a plate core is arranged on the insulating material, and a glass cover plate is covered on the plate core. Since there is only one layer of glass on the board core, the thermal insulation effect is poor, the temperature of hot water cannot be raised, and the thermal efficiency is low. And because the insulation layer under the board core is thick and heavy, it cannot be better combined with the building. Contents of the invention [0003] The object of the present invention is to provide a solar thermal collector with good thermal insulation effect, high thermal efficiency, low cost, light and thin, and better integrated with buildings. [0004] The solu...
