[0002] Ordinary solar water heaters use vacuum tubes to collect heat. Through the light-to-heat conversion of vacuum tubes, hot water is sent to the thermal insulation water tank through microcirculation. There are two disadvantages in this structure for users: one is that the water in the vacuum tube cannot be used when the user uses water. Taking the 1820 water heater as an example, the water capacity in the vacuum tube reaches 50L, and this part of the water cannot be used, which is bound to Causes a waste of resources; the other is that the water in the vacuum tube has not been used, and a large amount of scale will be generated. The scale adheres to the tube wall and affects the heat collection efficiency of the entire water heater.

Embodiment Construction
[0012] The present invention will be specifically described below in conjunction with the accompanying drawings and embodiments.
[0013] figure 1 Shown is a schematic diagram of the internal structure of the present invention.
[0014] figure 2 Shown is a schematic diagram of the internal structure of the present invention.
[0015] The present invention comprises conduit 1, manifold 2, vacuum pipe 3, water tank 4, inlet and outlet pipe 5 and 6 throttling valves.
[0016] There are some small holes in the middle of the conduit 1, which traverse the water tank 4 and can be fixed on the inner end cover of the water tank.
[0017] The vacuum tube 3 is provided with a manifold 2, one end of the manifold 2 communicates with the conduit 1 through a small hole, and the other end of the manifold 2 penetrates into the lower end of the vacuum tube 3.
[0018] The length of the manifold 2 is slightly shorter than the length of the vacuum tube 3 .
[0019] The header 2 is made of s...

The invention discloses a solar water heater with vacuum tubes internally provided with headers. The solar water heater comprises a water tank, a guide tube, the vacuum tubes and a water inlet and outlet tube, the guide tube is provided with a plurality of small holes in the middle, transversely penetrates in the water tank and is fixed on an inner end cover of the water tank, the headers are arranged in the vacuum tubes, one ends of the headers are communicated with the guide tube through the small holes, and the other ends of the headers stretch into the lower ends in the vacuum tubes; the water inlet and outlet tube is communicated and connected with the guide tube, a throttling valve is installed on the water inlet and outlet tube, and a spring and a rubber gasket boss are arranged in the throttling valve. According to the solar water heater, the headers connected with the guide tube are internally arranged in the vacuum tubes, water can be directly output from the headers in the vacuum tubes so that the water in the vacuum tubes can be used, water scale is prevented, the heat-collecting efficiency of the water heater is improved, meanwhile, resources are saved, and waste is reduced.
Description
technical field [0001] The invention relates to a solar water heating system, in particular to a solar water heating system with headers inside a vacuum tube, belonging to the technical field of solar water heaters. Background technique [0002] Ordinary solar water heaters use vacuum tubes to collect heat. Through the light-to-heat conversion of vacuum tubes, hot water is sent to the thermal insulation water tank through microcirculation. There are two disadvantages in this structure for users: one is that the water in the vacuum tube cannot be used when the user uses water. Taking the 1820 water heater as an example, the water capacity in the vacuum tube reaches 50L, and this part of the water cannot be used, which is bound to Cause waste of resources; another is that the water in the vacuum tube has not been used, and a large amount of scale will be generated, and the scale will adhere to the tube wall and affect the heat collection efficiency of the entire water heater. ...
