Description

Instant wall-mounted pressure-bearing solar water heater

(1) Technical field

The utility model belongs to the field of solar energy utilization, in particular to an instant thermal wall-mounted pressure-bearing solar water heater. the

(2) Background technology

The solar water heaters used today are generally installed on the roof or on the flat ground. It is rainy and frosty, and it is inconvenient to maintain. Especially the users of the entire building are installed on the roof, which is very crowded. At the same time, it is difficult to lay pipes, high cost, and low thermal efficiency. Single function. the

In addition, the mainstream electric water heaters and split-type water heaters on the market have the hidden danger of "explosion" due to design defects, which has troubled the majority of manufacturers and consumers; at the same time, because their water tanks contain stagnant water that cannot flow, it is easy to breed bacteria , and therefore cannot be referenced. the

Some manufacturers use low-grade products such as low-quality silicone rings and non-food-grade stainless steel liners, which will have certain side effects on the human body, and have not really met the requirements of drinking water standards. the

(3) Contents of the invention

In order to make up for the deficiencies of the prior art, the utility model provides an energy-saving, environment-friendly, safe and efficient instant thermal wall-mounted pressure-bearing solar water heater. the

The utility model is achieved through the following technical solutions:

An instant wall-mounted pressure-bearing solar water heater, including a vertically arranged water storage tank and vacuum heat collecting tubes connected horizontally to it, and its special feature is that the vacuum heat collecting tubes are symmetrically distributed on both sides of the water storage tank, and the water storage tank is provided with There are exhaust ports and water replenishment ports. Fully sealed U-shaped stainless steel bellows run through the vacuum heat collector tubes on both sides. The water inlet and outlet of the stainless steel bellows run through the entire water storage tank. The water storage tank and the vacuum heat collector tube are filled with heat storage medium. the

The utility model cancels the traditional hot water storage tank, leaving only the water storage tank for connection, and adopts a pressure-bearing design. Compared with the split solar energy, the water storage tank is integrated with the heat collection module, which has higher efficiency and lower temperature rise. faster. the

Due to the storage tank of the balcony wall-mounted solar water heater and the heat storage medium inside the vacuum tube, there is no artificial consumption after one-time injection, which greatly reduces the number of times the traditional need to add water to the solar water heater, thus improving the safety of the water heater; heat transfer medium The water storage tank and the vacuum tube are used as heat-conducting parts, and all the user’s water enters and exits through the U-shaped stainless steel bellows. When cold water flows through one end of the stainless steel bellows, the cold water will quickly communicate with the heat-conducting medium in the instant wall-mounted pressure-bearing solar water heater. Heat displacement is performed, and hot water flows out when the water outlet is opened. Compared with the traditional stainless steel pipe, the stainless steel bellows increases the heat exchange area with the heat storage medium by about 1.4 times, so that more hot water can be obtained quickly. the

Cold water is heated when it flows through the stainless steel bellows, and the water used is always flowing water, which ensures the cleanness of the water in the U-shaped stainless steel bellows, and at the same time ensures the drinking safety of the water, and can withstand high pressure. Once expanded the field of solar energy utilization. the

The pipe diameter of the vacuum heat collecting tube is 70 mm, and the vacuum heat collecting tube is an all-glass tube. Due to the large heat collecting area of the Φ70mm all-glass vacuum heat collecting tube and the relatively small water capacity of the balcony wall-mounted solar water heater, the temperature of the heat storage medium in the balcony wall-mounted solar water heater can reach a higher water temperature, thereby increasing the solar water heater. scope of application. the

An automatic exhaust device is installed on the exhaust port. The split-type automatic exhaust valve is improved to an automatic exhaust device, which completely eliminates the possibility of "explosion" of the water tank. the

The beneficial effects of the utility model are:

(1) It has the characteristics of innovation, rationality and versatility;

(2) It has the advantages of promoting thermal cycle, improving heat conduction efficiency and reducing energy consumption;

(3) Safer, more beautiful and reasonable design;

(4) Capable of bearing pressure;

(5) There is no scale accumulation in the vacuum tube, which is easy to operate and easy to use;

(6) Meet the standard of drinking water;

(7) High safety factor. the

(5) Specific implementation methods

Accompanying drawing is a kind of concrete embodiment of the utility model. This embodiment includes a vertically arranged water storage tank 1 and vacuum heat collecting tubes 2 horizontally connected to it. The vacuum heat collecting tubes 2 are symmetrically distributed on both sides of the water storage tank 1, and the water storage tank 1 is provided with an exhaust port 8 and a water supply port 7.

The Φ70mm all-glass vacuum heat collection tube 2 can quickly absorb sunlight with a huge heat collection area, convert it into heat energy, heat the heat storage medium 4, and store energy in the heat storage medium 4 with extremely high heat. When people need hot water, water enters the water heater through the water inlet 5 of the U-shaped stainless steel bellows 3, and the water in the U-shaped stainless steel bellows 3 exchanges heat with the heat storage medium 4 in the water heater. Make the water in the U-shaped stainless steel bellows 3 come out from the water outlet 6, and in this way, the heat energy in the heat storage medium 4 is replaced to obtain hot water. The used water for heat exchange with the heat storage medium 4 in the U-shaped stainless steel bellows 3 ensures the purity of the used water, thereby meeting the standard of the used water. the

This product changes the traditional practice of solar water heaters mainly storing heat in the hot water storage tank. It adopts Φ70mm all-glass vacuum heat collecting tube 2 to store the converted solar heat in Φ70mm all-glass vacuum heat collecting tube 2, and adopts integrated solar energy In the way of U-shaped stainless steel bellows 3, the water is directly heated in the U-shaped stainless steel bellows 3 without mixing with the heat storage medium 4, so that the product is under pressure, has a high safety factor, and has high reliability, ensuring drinking Water purity, thereby expanding the effective use of solar heat, to achieve energy-saving and environmental protection effects. the
