Abstract

The invention discloses a solar water heater, which comprises a water tank, wherein the water tank is used for storing heated hot water and is of a cube structure, a heat insulation layer is arranged outside the cube structure, the heat insulation layer is a heat insulation building block and is formed by compounding a concrete substrate (1) and a vacuum heat insulation plate (2), the vacuum heat insulation plate (2) is positioned in an open groove of the concrete substrate (1), and mortices (3) and glossal grooves (4) are formed at the upper and lower sides and the left side and the right side of the heat insulation building block. The solar water heater has the advantages that the heat insulation building bock is adopted, the heat loss is effectively prevented, and the energy sources are saved.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a composite thermal insulation block of a vacuum thermal insulation board. Background technique [0002] 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 insulation layer, thereby greatly saving space and materials, and reducing Consumption of petrochemicals. [0003] With the rapid development of my country's economy and the improvement of people's living standards, people's requirements for living comfort are getting higher and higher. Improving living comfort in existing non-en...
