Description

Vacuum Insulated Flat Panel Solar Collector

technical field

The utility model relates to a solar heat collector, in particular to a vacuum heat preservation flat solar heat collector.

Background technique

The traditional flat-panel solar collector is mainly composed of four frames connected by the shell, installed in the closed space of the shell assembled by the frame, the heat absorbing plate is installed in the shell assembled by the frame The upper part of the transparent cover plate is composed of the lower bead and back plate installed at the bottom of the shell assembled from the frame, and the row pipe and header arranged at the lower part of the heat-absorbing plate. The transparent cover plate is compressed by four upper bead bars. On the upper part of the shell assembled from the frame, and fixed by fasteners, the upper bead has a butt joint at each corner and forms a sharp corner. The butt joint will cause water leakage, and the sharp corner will hurt people. And influence the attractive in appearance of product, complex structure, difficult installation. In addition, it is necessary to install thermal insulation material on the upper part of the back plate for thermal insulation. Since the thermal insulation material will generate volatiles and absorb moisture, the thermal insulation performance of the thermal insulation material will be greatly reduced, which is not conducive to improving the thermal efficiency of the flat solar collector. Furthermore, the shell of a traditional flat solar collector is formed by welding four independent frames, which is prone to welding quality problems and high production costs.

In order to achieve the above purpose, the technical solution provided by the utility model is as follows: provide a vacuum heat preservation flat solar collector, including a collector shell, a heat absorbing plate core installed in the heat collector shell, and a heat collector A transparent cover plate that is sealed and connected to the upper opening of the shell. The collector shell is composed of an inner shell and an outer shell. The upper end of the inner shell is sealed and connected with the upper end of the outer shell. The vacuum insulation interlayer is formed by vacuuming.

The vacuum insulation interlayer is provided with an opening for the header to protrude from the opening, and a sealing ring is installed in the opening.

The opening is formed by a casing whose one end is connected with the inner casing and the other end is connected with the outer casing, and the header protrudes from the casing.

The beneficial effect of the vacuum heat preservation flat solar heat collector described in the utility model is: by constructing a heat collector shell composed of an inner shell and an outer shell, the upper end of the inner shell is sealed and connected with the upper end of the outer shell, and the inner shell A vacuum insulation interlayer is formed between the upper end of the body and the outer shell by vacuuming. Therefore, the vacuum heat preservation in the flat solar heat collector is realized, the heat preservation performance is good, the heat loss of the flat solar heat collector is greatly reduced, and the thermal efficiency of the flat solar heat collector can be improved. And there is no need to install thermal insulation materials in the collector shell, which not only saves materials, but also solves the problem that traditional flat solar collectors need to install thermal insulation materials in the collector shell for thermal insulation. The existing thermal insulation materials will absorb moisture and keep warm The material will produce volatile matter and lead to poor thermal insulation performance, which is not conducive to the technical problem of improving the thermal efficiency of the flat-panel solar collector.

In addition, the inner shell and the outer shell are integrally formed separately. When assembling, only the upper end of the inner shell and the upper end of the outer shell need to be sealed and connected, and the flat solar collector is put into the collector shell, and the heat collector shell is passed through the sealing material. Sealed connection with the transparent cover plate can complete the assembly of the flat solar collector, which greatly simplifies the installation process of the flat solar collector, and can complete the assembly of the collector shell, which is easy to install and does not leave a butt joint Seams or sharp corners can effectively prevent water leakage and injury accidents, and the product has a beautiful appearance.

The vacuum heat preservation flat solar heat collector of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
