Abstract

The invention relates to a solar water heating device integrating vacuum heat collection and water storage, which belongs to the technical field of solar energy application. The device has a box body with a two-layered box wall, a water-storage chamber defined by the inner box wall, a vacuum heat-collection layer arranged between the front inner wall and the outer wall. The vacuum heat-collection layer has a transparent plate as the outer box wall plate and a gradually-changed aluminum / nitrogen film on the opposite inner box wall plate. The space between the inner and outer box walls is packed with heat-insulating materials to form a heat-insulating layer or a vacuum heat-collection layer. A hot water outlet pipe interface and a cold water inlet pipe interface are arranged on the lower end surface of the device. The device integrates the functions of water storage and heat collection, can increase the heat-collection and heat-insulation efficiency, and also has the advantages of environmental protection, low manufacturing cost, easy installation and maintenance, and wide application range.

Description

technical field [0001] The invention belongs to the technical field of solar energy application, and in particular relates to the structural design of a solar water heater device. Background technique [0002] Solar collectors are the main components of solar water heaters. It mainly uses water as the carrier to convert solar energy into heat energy, so as to realize the application of solar water heaters. [0003] The first generation of flat solar collectors separates heat collection from water storage, and the water storage tank is insulated. The hot water is sent to the storage tank through the heat collecting plate. But this device has several problems: A. It cannot keep warm at night, and the temperature of the hot water in the water storage tank is affected; B. It freezes in winter and the container bursts; C. The thermal efficiency is low. [0004] Now there are also products that have been improved on flat plate heat collectors. For example, instead of directly a...
