Abstract
The invention discloses a solar water heater, which comprises a water tank for storing heated hot water, wherein the water tank is of a cubic structure, and a heat-preservation layer is arranged on the outside of the cubic structure; the heat-preservation layer is a heat-preservation building block; the heat-preservation building block is formed by combining a concrete substrate (1) and a vacuum insulation panel (2); the vacuum insulation panel (2) is positioned in an open groove of the concrete substrate (1); self-defined grooves are formed in the left and right sides of the heat-preservation building block, and polystyrene boards or inorganic heat-preservation mortar can be filled in the self-defined grooves to partition a thermal bridge. The solar water heater is provided with the heat-preservation building block, so that the loss of heat is effectively prevented, and energy resources are saved.
Description
technical field [0001] The invention belongs to the field of solar energy, in particular to a solar water heater with a thermal insulation structure, which belongs to the field of F24J. Background technique [0002] Solar energy is an inexhaustible clean energy with a huge amount of resources. All countries in the world have taken the use of solar energy as an important item in the development of new energy. The Chinese government has also clearly stated in the "Government Work Report" To actively develop new energy. [0003] Vacuum insulation panels (Chinese patent CN102720922B) are based on the principle of vacuum insulation, and reduce convection and radiation heat transfer by maximizing the vacuum inside the panels and filling them with core insulation materials. The thermal conductivity can reach 0.003W / (m·K)~0.008W / (m·K), and its performance is far superior to that of ordinary thermal insulation materials, which can greatly reduce the thickness of the thermal insulati...
