Description

A New High Efficiency Solar Water Heater

Technical field:

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

Background technique:

Solar water heaters have outstanding advantages such as green environmental protection and energy saving, which has become a consensus among people. Whether it is a rural area or a city, whether it is a newly built community or an old-fashioned residence, any household who can use solar water heaters will use it on the roof, or on the wall, or on the balcony. Solar water heaters are installed on the wall for living and bathing purposes. Due to the rapid popularization of solar water heaters and the large market demand, the manufacturers of solar water heaters have also sprung up. Therefore, solar water heaters have the following defects: First, the degree of generalization and standardization is low, especially the integration of different types of water heaters. The solar water heaters produced by the manufacturer are installed on the same roof, and the water heaters with the same displacement have different dimensions, different heights, different lengths, and different angles. The installed solar water heaters have been rehabilitated with "one line from east to west and one side to the south", which wastes manpower and resources. The second is solar water heaters that occupy the same space. In order to obtain higher water temperature, manufacturers generally increase the temperature by increasing the length and thickness of the vacuum tube, or heating with electricity, but the effect is still unsatisfactory. Third, during the installation of the water heater, the upper and lower water pipes connected to the water tank, the insulation pipes outside the upper and lower water pipes, as well as the wires for electric heating and electronic emptying valves, etc., are all exposed on the outer periphery of the water tank. And come off downwards, neither attractive in appearance, more unfavorable for heat preservation and safe use. The 4th, the reflector that is positioned at the vacuum tube below is too close (about 10 centimeters) to the vacuum tube, and the reflective effect is unsatisfactory.

Invention content:

The technical problem to be solved by the utility model is to provide a new high-efficiency solar water heater with large heat collection area and high heat collection efficiency. The height and angle of the solar water heater can be adjusted during installation. At the same time, the pipes and lines around the water tank are enclosed in the box. Beautiful and safe.

The utility model is realized through the following technical solutions:

A new type of high-efficiency solar water heater, including a water storage tank, a vacuum heat collection tube arranged on a support and connected to the water storage tank, characterized in that the sun-facing surface of the water storage tank is coaxially arranged with heat collection tubes, and one end of the heat collection tube is connected to the Commissioned, the other end communicates with the connector, and the connector communicates with the water storage tank.

The cross section of the water storage tank is oval, or circular, or semicircular, or rectangular, or polygonal.

The sun-facing surface of the water storage tank and the coaxially arranged heat-collecting tubes are vacuum heat-collecting tubes or heat-pipe-type vacuum heat-collecting tubes.

The rear bracket of the bracket is composed of an upper bracket and a lower bracket, and the connecting ends of the upper bracket and the lower bracket are respectively provided with more than one connecting hole, and are connected with bolts passing through the connecting holes of the two; the connecting ends of the front bracket and the upper bracket More than one connecting hole is provided respectively, and bolts are used to pass through the connecting holes of the two to connect;

The bottom of the water storage tank is connected with an integrated control box, and the bottom of the integrated control box is provided with outlet holes for pipes and wires.

A reflector is connected to the support below the vacuum heat collecting tube, and the reflector is 20-40 centimeters away from the vacuum heat collecting tube, preferably 30 centimeters.

Beneficial effect:

1. In the utility model, 5-8 heat pipe-type vacuum heat-collecting tubes or water-flowing vacuum heat-collecting tubes are arranged coaxially with the water storage tank on the sunny side of the water storage tank, which greatly increases the heat-collecting area. Compared with the solar water heaters of the same type (such as 16 pieces, 1.8m in length, ф58mm in diameter, and 130 liters in water capacity), the utility model is equipped with six 1.2-meter-long heat pipe vacuum heat collecting tubes on the sunny side of the water storage tank. , which increases the lighting area of 0.34m ² , since the maximum temperature of the heat pipe can reach above 250°C, it has the advantages of large heat collection area and high heat collection efficiency, and can save space.

2. The height and angle of the bracket in the utility model are adjustable, so that the installed solar water heaters are uniform and coordinated with buildings, which not only provides convenience for life, but also beautifies the space environment. And avoid the trouble of sawing the legs (brackets) or heightening the brackets, saving manpower and installation costs.

3. Since the utility model is equipped with an integrated control box, the joints of the upper and lower water pipes connected to the water storage tank, the insulation pipes outside the upper and lower water pipes, electric heating, and electric wires for the electronic emptying valve are all sealed in the integrated control box. Inside, it solves the problems of poor fixation, easy falling off, and easy freezing between the insulation pipe and the water storage tank, and the problems of fatigue, cracking, falling off and water leakage at the joints between the upper and lower water pipes and the water storage tank. Various wire connectors are wound on the bracket, easy to break, Unsafe and unsightly issues.

Four, the reflective plate arranged below the vacuum heat collecting tube in the utility model, its surface is 20-40 centimeters away from the lower surface of the vacuum heat collecting tube, which is more beneficial to reflect, refract and radiate sunlight to the semicircular arc heat-absorbing surface under the vacuum tube, The heat collection efficiency of the vacuum heat collection tube is improved.
