Description

Technical Field

[0001] The utility model relates to a solar energy utilization technology, in particular to a combined flat-plate solar water heating and heating integrated machine. Background Art

[0002] Flat plate water heaters are split and integrated, both of which consist of a flat plate collector, a jacketed water tank and a bracket. There is antifreeze in the flow channel of the flat plate and the jacket of the water tank. The flat plate collector absorbs the sun's light energy during the day and converts it into heat energy, heating the antifreeze in the flow channel of the flat plate. The density of the antifreeze decreases due to heat, and it circulates with the antifreeze in the jacket. As the temperature of the antifreeze in the jacket increases, the heat is transferred to the water tank, heating the water in the water tank, and finally storing the heat in the water tank. Since the jacketed water tank is mostly made of pressure-bearing enamel material and the water tank is heavy, a 150L water tank weighs 50KG. As the water tank increases, more flat plates are needed, and the weight of the water tank will be even greater, making it more difficult to transport the production machine.

[0018] The specific technical solutions of the present invention are further described below. To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer and to facilitate those skilled in the art to further understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them, and do not constitute a limitation on the rights thereof. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of protection of the present invention.

[0019] A combined flat-plate solar water heating and heating machine.

[0020] As shown in the figure: the product consists of three parts: water tank 2, flat plate 6, and bracket; the heat exchanger 3 is fixed in the water tank; the flat plate is connected to the heat exchanger through a bellows 5, and antifreeze is filled inside to ensure that it will not freeze in severe winter weather. The heat exchanger is in direct contact with the water in the water tank, which can ensure heat exchange efficiency;

[0021] The flat panel absorbs sunlight during the day and converts it into heat energy, which heats the antifreeze inside the flat panel and exchanges heat with the water in the water tank through the internal heat exchanger, with high heat exchange efficiency.

[0022] The heat exchanger and water tank are welded with thin-walled stainless steel, which is light in weight. A 150L water tank weighs about 30KG. There are three ports on the heat exchanger. The inlet and outlet are at both ends of the inner tank. The inlet is higher and the outlet is lower, ensuring that the low-temperature antifreeze with higher density flows into the plate at the outlet. After being heated by the plate, the high-temperature antifreeze with lower density flows into the heat exchanger at the inlet. The antifreeze injection port is installed on the heat exchanger.

[0023] The three openings of the heat exchanger are welded and fixed to the inner tank of the water tank, and extend out of the water tank, wherein the heat exchanger pipe openings on the left and right are welded.

[0024] A sub-water tank 4 is installed on the water tank. The product is written with automatic water filling, and the water stops automatically when it is full. The water in the sub-water tank enters the lower part of the solar water tank through the water inlet, and the hot water outlet 1 is in the upper middle part of the other side. Cold water enters and hot water exits, which can realize top water operation and ensure that hot water is taken out as much as possible.

[0025] The outer wall of the heat exchange liner can be coated with anti-scaling material to ensure that the surface of the heat exchange liner is smooth and the heat exchange effect is increased without affecting the heat exchange effect.

[0026] By adding flat plates and connecting multiple flat plates in series, the heat collection area can be increased. By lengthening the water tank, the capacity of a single water tank can reach 600 kilograms, making installation more convenient.

[0027] A heat exchange structure for heating, such as a heat exchange coil or a heat exchange water tank, can be added to the water tank to achieve the dual functions of hot water and heating. The water in the water tank can be used to store heat, and domestic hot water can be provided through the coil or the heat exchange water tank to achieve pressure-bearing operation.
