Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] The diversion solar water heater, as shown in the accompanying drawings, includes a bracket 10 and a plurality of heat collecting tubes fixedly installed side by side on the bracket 10, the upper and lower ends of the bracket 10 are fixedly installed with an upper collar 9 and a lower collar 3, The nozzle and the bottom end of the heat collecting tube are respectively inserted into the upper collar 9 and the lower collar 3 through rubber rings; the upper collar 9 is fixedly connected with the sealing cover 12 of the heat collecting tube by bolts, and the lower collar 3 is fixedly connected by bolts There are 2 trays. The heat collecting tube is mainly composed of a large-diameter vacuum glass tube 4 with good thermal insulation effect on the outer layer and a metal tube 5 on the inner layer. The outer wall of the metal tube 5 is coated w...

Abstract

The invention relates to diversion type solar water heater. It includes frame and at least one heat collection tube. The latter is made up of outer vacuum glass tube and inner metal tube. The out wall of the metal tube is coated by selective absorption coating. And its upper end is welded sealing cover. The sealing cover is set water inlet and back water opening. The former is set water pipe. And the latter is set back water tube. It can simplify structure, reduce cost, and has many mounting means to fit different buildings.

Description

technical field [0001] The invention relates to a solar water heating device, in particular to a diversion type solar water heater. Background technique [0002] Solar energy is a kind of new energy and renewable energy, and solar water heater is one of the main products of solar thermal utilization. At present, the main structural components of commonly used solar water heaters are: a support, a plurality of heat collecting tubes and heat storage tanks installed on the support, and pipes communicating with waterways. During installation, the tube body of the heat collecting tube should be inclined, the mouth of the tube should be upward and connected with the hot water storage tank, and the heat collecting tube should be used to collect the water in the solar heating tube, and the hot water in the heat collecting tube and the hot water storage tank should be circulated. heat exchange. This kind of solar water heater needs to use a water storage tank to store hot water, an...
