AI Technical Summary
Technical Problem
In existing solar collectors, the heat loss from the glass cover is significant, resulting in low thermal efficiency.
Method used
A first heat insulation element is set between the heat-absorbing element and the transparent cover plate, dividing it into two sub-heat-absorbing chambers. This increases the thermal resistance to reduce heat transfer to the transparent cover plate and reduce heat loss.
Benefits of technology
By incorporating heat insulation components, heat transfer between the transparent cover and the outside air is reduced, thereby improving the thermal efficiency of the solar collector.

Abstract
The utility model belongs to the technical field of solar water heaters, and particularly relates to a solar heat collector and a solar water heating system. The solar heat collector comprises a shell, a heat absorption part, a transparent cover plate and a first heat insulation part, the heat absorption part is located in the shell and used for absorbing solar energy, the shell is covered with the transparent cover plate, a heat absorption cavity is formed between the transparent cover plate and the heat absorption part, and the first heat insulation part is connected with the shell and located between the heat absorption part and the transparent cover plate. The first heat insulation piece divides the heat absorption cavity into two sub heat absorption cavities. According to the solar heat collector provided by the embodiment of the invention, the heat dissipation loss of the transparent cover plate can be reduced, the heat loss of the solar heat collector is reduced, and the heat efficiency of the solar heat collector is improved.
