Abstract
Description
Technical Field
[0001] This invention relates to the field of solar energy applications. Specifically, it relates to solar energy heat absorption and insulation devices. Background Technology
[0002] Currently, there is a heat-absorbing and heat-insulating double-layer technology on the market. It utilizes vacuum insulation and a heat-absorbing coating. However, during manufacturing, when air is pumped out to create a vacuum, negative pressure is generated, causing the translucent glass to shatter. This presents production difficulties. Summary of the Invention
[0003] To overcome this difficulty, the present invention provides the following heat absorption and insulation devices: 1. A solar heat absorption and insulation device (hereinafter referred to as a heat absorption plate): It mainly consists of a metal water tank, a sealing ring, and transparent glass. A sealing ring is placed inside the water tank, and transparent glass is placed on top of the sealing ring. Carbon dioxide gas or dry ice is filled into the gap between the transparent glass and the water tank, and then the tank is sealed.
[0004] II. Solar-Powered Insulated Hot Water Tank: It mainly consists of a heat-absorbing plate, a metal water tank, heat-resistant insulation material, and an outer shell. The heat-absorbing plate is welded to the water tank to form a water tank. Heat-resistant insulation material is wrapped around any areas without transparent glass, and then the outer shell is fitted over it. Alternatively, heat-resistant insulation material can be filled into the interlayer between the water tank and the outer shell.
[0005] 3. Solar steam oven: It is mainly a cube, cuboid, or irregular polyhedron, with one or more sides being heat-absorbing plates and the rest being heat-insulating and heat-resistant material plates. Attached Figure Description

[0008] The following is a clear and complete list of several options: 1. The features of the heat absorber plate include: a metal water tank, a sealing ring, and transparent glass. A sealing ring is placed around the water tank, and then the transparent glass is placed on top of the sealing ring. The gap between the transparent glass and the metal water tank is filled with carbon dioxide gas or dry ice, and then sealed.
