Problems solved by technology

A general split pressurized solar water heater consists of three modules: a vacuum collector, a solar workstation including a circulating pump, and a pressurized water tank, with a complex structure; an integrated non-pressurized solar water heater not only has a huge cylinder Type water tank, also because the vacuum heat collecting tubes are arranged vertically, it must maintain a certain inclination angle with the sun in order to obtain high heat rate, so an inclination angle bracket is needed, the water in the tubes cannot be exhausted, and the remaining water is unclean, and the volume Huge, with high wind resistance, unable to withstand strong typhoons, placed on the top of a house with limited area and unknown property rights, it is easy to cause civil disputes, the water pipeline is long, it is easy to freeze and crack in winter, and it is not easy to integrate buildings. It is not beautiful, so it is a bit high-end Residential districts are also restricted; the existing integrated pressure-bearing solar water heater and the integrated non-pressure-bearing solar water heater have the same appearance structure and disadvantages

Embodiment 1

[0021] Reference attached figure 1 , A solar water heater, comprising a heat collector composed of heat collecting pipes, and a water storage tank 1. The water storage tank is a loop structure surrounded by a pipeline, and the loop pipeline is provided with a water inlet 2 corresponding to the lower position. The loop-shaped pipeline is provided with a water outlet 3 at a corresponding high position. The loop-shaped frame enclosed by the loop-shaped pipeline has a plate structure; the heat collector is arranged in the loop-shaped frame, and the heat collector consists of multiple The glass vacuum heat collecting tube 4 arranged in parallel in parallel is composed of glass vacuum heat collecting tube 4, one end of the glass vacuum heat collecting tube is closed, the other end is open, and the open end is connected with the adjacent loop pipeline; There is a pressure-regulating expansion tank and a pressure-relieving exhaust valve 6. The expansion tank is composed of a tank body 5...

Embodiment 2

[0026] Reference image 3 The water storage tank of the loop structure surrounded by pipelines is composed of two loop pipelines 31, 32 connected, and the heat collecting tube is arranged in the middle frame enclosed by the two loop pipelines. It is a heat pipe evacuated heat collection tube, which is composed of a vacuum glass tube 41 and a copper tube 42. The large-diameter sealed end 43 of the copper tube extends into the loop pipe. This heat collection tube is more capable of bearing After the vacuum tube is broken, the water will not be lost. Others are the same as the first embodiment.

[0027] Of course, the heat collector is not only limited to a structure composed of heat collecting tubes, but may also be a heat collecting plate structure, and the heating effect is achieved through heat transfer between the heat collecting plate and the loop pipe.

Abstract

The invention relates to a solar water heater which comprises a heat collector formed by heat collection pipes and a water storage tank. The water storage tank is in a square-hole structure enclosed by a pipeline, the square-hole pipeline is provided with a water inlet corresponding to a low position and is provided with a water outlet corresponding to a high position, and a square-hole frame enclosed by the square-hole pipeline is of a plate structure; the heat collector is arranged in the square-hole frame and is formed by a plurality of heat collection pipes which are horizontally arrangedin parallel, and one end of each heat collection pipe is arranged in the square-hole pipeline to carry out heat transfer with the square-hole pipeline; the square-hole pipeline is provided with an expansion tank for pressure regulation and an exhaust valve for pressure release. The invention adopts the plate type square-hole frame structure. The heat collection pipes which are horizontally arranged is not limited by sunlight angles having the same illumination area and the same thermal recovery effect, and only needs to be arranged facing to the south without needing to be equipped with an inclined bracket. The invention is convenient to use, and saves the cost.

Description

(1) Technical field [0001] The invention relates to a solar water heater. (2) Background technology [0002] Solar water heaters generally include split pressure solar water heaters, integrated non-pressure solar water heaters and integrated pressure solar water heaters. The general split pressurized solar water heater consists of three modules: a vacuum collector, a solar workstation including a circulating pump, and a pressurized water tank. The structure is complex; the integrated non-pressurized solar water heater not only has a huge tube Type water tank, because the vacuum collector tubes are arranged upright, they must maintain a certain inclination angle with the sun in order to get a high heat rate. Therefore, an inclination bracket is required. The water in the tube cannot be used up, and the remaining water is not clean. Large, large wind resistance, unable to resist strong typhoons, placed on the top of a house with limited area and unknown property rights, it is easy...
