Description

A solar water heater

technical field

The utility model relates to the field of solar water heaters, in particular to a solar water heater.

Background technique

A solar water heater is a heating device that converts sunlight energy into heat energy, and heats water from low temperature to high temperature, so as to meet the hot water use in people's life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structure. The vacuum tube solar water heaters are the main ones, accounting for 95% of the domestic market share. Vacuum tube household solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into heat mainly depends on vacuum heat collecting tubes. Get the hot water you need.

Existing solar water heaters all include multiple heat collecting tubes connected to the water tank. Whether it is from the assembly of the solar water heater in the early stage or the cleaning of the heat collecting tubes in the later stage, it needs to be processed one by one, which is time-consuming and laborious. , due to the limited heat absorption due to the length limitation, the temperature rise rate of the cold water in the water tank is relatively slow; in addition, the heat collecting pipe is connected with the water tank through a seal, and the heat collecting pipe has been in the working environment of alternating cold and hot, especially in the cold northern region, due to The existing heat collecting tubes are all straight structures, so that there is no room for thermal expansion and contraction of the heat collecting tubes. Due to the problem of thermal expansion and cold contraction, the seals connected to it will be pulled, resulting in hidden dangers in the sealing of the heat collecting tubes and the water tank; at the same time, the existing The solar water heater water tank is basically designed as a round water tank. It is made of a single plate and then buckled. The manufacturing process is complicated, and the fixation with the bracket is poor.

Utility model content

In order to solve the above-mentioned defects in the prior art, the application provides a solar water heater, the heat collecting tube of which is easy to assemble and clean, the structure of the water tank is simple and easy to process and manufacture, and the sealing stability of the heat collecting tube and the water tank is stronger overall. The heat-absorbing efficiency of the heat-collecting tube is higher, and the temperature of the cold water rises faster. The technical scheme is as follows:

A solar water heater, comprising a water tank, a support frame and a heat collector, the heat collector is a heat collecting pipe, the two ends of the heat collecting pipe are respectively connected with connecting pipes through corrugated pipes, and the connecting pipes communicate with the water tank, so The heat collecting tube includes a first pipe section extending from the top to the bottom at one end and a second pipe section at the other end, and a serpentine connecting pipe section is arranged between the first pipe section and the second pipe section. In the pipeline section, the heat collector is installed on the supporting frame below, and the bottom end of the supporting frame is provided with a limit rib, which is used to fix the heat collector from the bottom. The two sides of the supporting frame are angle steel, which is used To fix the heat collector from the side, the water tank is fixed on the top of the support frame, and the outer shell of the water tank is formed by welding four arc-shaped plates, four flat plates and two end cover plates.

Further, a bending section is also provided on the first pipeline section and the second pipeline section. A bending section is set on both the first pipe section and the second pipe section, so that the whole heat collecting tube has room for thermal expansion and contraction, which greatly reduces the probability of breaking due to thermal expansion and contraction, and the service life is longer Long, more reliable performance; in addition, the small deformation of thermal expansion and contraction will be transferred to the bending section and released, so that the seal connected to it will not be pulled, and the hidden danger of sealing between the heat collecting tube and the water tank will be solved.

Further, the first pipeline section, the second pipeline section and the serpentine pipeline section are integrated.

Further, the bellows are high temperature resistant rubber bellows.

Further, the bellows is tightly connected with the first pipeline section, the second pipeline section and the connecting pipe through a hoop.

Further, two mounting holes for inserting the heat collecting tubes are opened on the plane plate. By improving the existing heat collector, it is designed to be only one heat collecting tube, and correspondingly, the installation holes of the water tank connected with the heat collecting tube are only shortened to 2, greatly reducing the number of openings on the water tank , reducing the workload of drilling.

According to the above technical scheme, the heat collector of the present invention is a heat collecting pipe composed of the first pipe section, the second pipe section and the serpentine pipe section. It is only a pipe structure, which greatly reduces the pre-assembly and later stage Due to the workload of cleaning, the cold water entering the heat collecting tube needs to go through a more winding and narrow pipeline, so that the temperature rise rate of the cold water is faster; at the same time, the two ends of the heat collecting tube are respectively connected with connecting pipes through corrugated pipes. Connected to the water tank, even if the heat collecting tube is always in the working environment of alternating cold and hot, the small deformation of its thermal expansion and contraction will be transmitted to the bellows and the bending section to be released, so that the seal connected to it will not be pulled, which solves the problem There are hidden dangers in the sealing of the heat collecting tube and the water tank; the water tank of the utility model has changed the manufacturing process of the traditional circular water tank which is made of a single plate rolled and buckled, and it is welded by multiple arc-shaped plates, flat plates and end cover plates , easy to manufacture, and its flat structure is more firmly combined with the bracket, and it is also suitable for the installation environment that is attached to or embedded in the building roof.
