All-glass vacuum tube type solar water heater with pressure-proof inner containers

Abstract

The invention relates to an all-glass vacuum tube type solar water heater with a pressure-proof inner containers, belonging to the technical field of solar equipment and comprising an insulating pressure-proof water tank, a steel frame and a plurality of double-glass vacuum heat-collecting tubes, wherein the insulating pressure-proof water tank is fixed on the steel frame, the outer part thereof is provided with an insulating layer, and the bottom part thereof is provided with a connecting port; the upper ends of the double-glass vacuum heat-collecting tubes are positioned in the insulating layer of the insulating pressure-proof water tank, the lower ends thereof are fixedly connected with the steel frame, and the inner parts thereof are provided with containers; the upper ends of the containers are fixedly connected with a connecting port of the insulating pressure-proof water tank by a sealing device, and the lower ends thereof are closed; the containers comprise stainless steel foils and elastic heat-proof rubber sheets, wherein the stainless steel foils are shaped like an arc-shaped barrel and are attached to one side of a heat-absorbing surface of each double-glass vacuum heat-collecting tube; and the elastic heat-proof rubber sheets are positioned at openings of the inner sides of the stainless steel foils and are fixedly connected with the stainless steel foils in a sealing manner. The all-glass vacuum tube type solar water heater has high heat-collecting efficiency, good safety and strong pressure-proof capability.

Description

technical field [0001] The invention relates to a water heater in the technical field of solar energy equipment, in particular to an all-glass vacuum tube solar water heater with a pressure-resistant inner tank. Background technique [0002] The limitation of conventional energy resources and the increase of environmental pressure have made countries around the world strengthen their support for the development of new energy and renewable energy technologies. An important part of the strategy, solar water heaters have been widely used at home and abroad for their high efficiency and low price. At present, most of the solar water heaters used by families, enterprises and institutions in our country are all-glass vacuum tube solar water heaters. This kind of solar water heater has the advantages of low cost and high solar energy utilization rate, but its pressure resistance and safety are relatively low. If the vacuum tube bursts, the hot water in the water heater will all ov...

Problems solved by technology

Although the water heater of this utility model can continue to work after the vacuum heat collecting tube is damaged, the heating effect is poor and the thermal efficiency is low due to the large air layer between the metal tube and the vacuum tube.
