Description

A solar water heater integrated with buildings

technical field

The utility model belongs to the technical field of energy, relates to a solar water heater, in particular to a solar water heater integrated with a building.

Background technique

The existing top-mounted solar water heaters are usually installed on the roof after the residential building is repaired, and the water pipes are introduced into the room from the exhaust duct or the vent hole. These solar water heaters generally have the following shortcomings: 1. Installation is troublesome, because there is no special fixed The mechanism can usually only be fixed by pulling iron wires vertically and horizontally on the roof to find a place, which is very inconvenient to install, and the safety is low, which is likely to cause safety hazards. 2. It is easy to freeze the water pipes in winter, and it is inconvenient to maintain. 3. It is easy to cause damage to the waterproof layer of the roof. The legs of the solar water heater are easy to break and wear the waterproof layer of the roof, causing the roof to leak. 4. Installed on the roof, it fails to be organically combined with the building and destroys the overall beauty of the building. It not only affects the appearance of the city, but also takes up a lot of roof space and area. Since each solar water heater is independent of each other, it must be placed at a certain distance. If Every household in a building puts one on the roof, and there must be no room for them. Existing solar water heaters generally have a water storage tank connected to the heat collector through pipelines, the pipelines are complicated, the heat loss is relatively large, and the amount of cold water released during use is relatively large.

Contents of the invention

The technical problem to be solved by the utility model is: the existing water heater is inconvenient to install, affects the overall appearance of the building, and needs to drain a large amount of cold water during use.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a solar water heater integrated with a building, including a bracket and a pipe, and is characterized in that it also includes a heat storage tank, a heat collection tube, a heat exchanger and a heat storage The heat storage medium in the tank; the heat collecting tube is connected to the two wings of the heat storage tank, the end away from the heat storage tank is closed, and the end connected to the heat storage tank is open; the heat exchanger is placed in the heat storage tank and the heat storage medium Included, the heat exchanger is a helically wound metal tube.

As a further improvement of the utility model, the closed end of the heat collecting tube is lower than the open end.

The heat collecting tube is a double-layer vacuum glass tube.

There are multiple heat collecting tubes, and the distance between them is more than 65mm.

The metal pipe is a copper pipe, and the metal pipe may also be an aluminum pipe.

The heat storage tank is composed of an inner container, an outer shell and an insulating layer sandwiched between them.

The heat storage tank is vertically fixed on the support.

The heat storage tank is filled with heat storage medium. The heat storage medium can be water, or an aqueous solution of inorganic salt or ethylene glycol, dichloromethane and other aqueous solutions. When the sun shines, the heat collecting tube absorbs sunlight and converts solar light energy The temperature of the heat storage medium in the heat collection tube is increased; in this way, the temperature of the heat storage medium in the heat collection tube is higher than that of the heat storage medium in the heat storage tank, and because the closed end of the heat collection tube is lower than the open connection end, Therefore, the heat storage medium will generate convection soon, and then the temperature of the heat storage medium in the heat storage tank will continue to rise to achieve the purpose of storing heat. When hot water needs to be used, the cold water is passed through the pipeline through the heat exchanger in the heat storage tank, and the cold water in the pipeline can be directly transported out after heat exchange and heating up.

The heat storage tank of the utility model is placed vertically, and the heat collecting pipes are located on both wings of the heat storage tank, so the utility model can be erected on the balcony and integrated with the balcony. Installed on the balcony of each household, the appearance is integrated with the windows and balconies of the residential building, and will not damage the overall beauty of the building. Because the installation location is on the user's own balcony, the installation is not only firm, but also more convenient for daily maintenance and repair than solar water heaters installed on the roof. The utility model does not need to install a bucket specially for storing hot water, and there are few pipeline installations. When using it, the cold water in the water storage tank does not need to be released in advance, and the amount of water released is less than that installed on the roof; the heat storage medium can use inorganic salt solution or ethylene glycol. , dichloromethane and other aqueous solutions to prevent freezing in winter. The water is directly exchanged through the heat exchanger in the heat storage tank. It does not need to be stored in advance, which can save a lot of water and reduce waste. The water quality and pressure of the hot water are also the same as those of the cold water. People feel more comfortable and healthier when using it.

Detailed ways

As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the heat storage tank 1 is composed of an outer shell 2, an inner tank 3 and an insulating layer 4 sandwiched between them, and an end cover 5 is arranged on the top thereof. An air outlet 13 is provided under the front end cover of the heat storage tank, and a drain hole 14 is provided at the bottom of the front of the heat storage tank. A water outlet 15 and a heat storage medium inlet 16 are arranged at the top of the back of the heat storage tank, and a water inlet 17 and a reserved hole 18 are arranged at the bottom of the back of the heat storage tank, and the reserved hole can be used to supplement an external heating source.

A heat exchanger 6 is arranged in the inner tank of the heat storage tank. The heat exchanger is composed of a copper tube with good thermal conductivity, and the lower end of the heat exchanger is connected to the water inlet 17 of the heat storage tank, and the upper end is connected to the water inlet of the heat storage tank. Water outlet 15. The two wings of the heat storage box 1 are respectively connected with 12 heat collecting tubes 7, and the open ends of the heat collecting tubes 7 are inserted into the heat storage box to form a whole with the heat storage box. A sealing ring 8 is arranged between the heat collecting tube and the inner tank of the heat storage box, and a dustproof ring 9 is arranged between the outer shell of the heat storage box. The closed end of the heat collecting tube is connected to the tube bracket 11 through the tube bracket 10, and the closed end of the heat collecting tube is lower than the open end. The pipe bracket 11 is connected to the heat storage tank 1 through the support 12, so that the heat storage tank is erected in the bracket, so that the whole water heater becomes a fixed whole, and then vertically fixed on the balcony, and integrated with the balcony, it is very firm, and beautiful.

During use, water is used as the heat storage medium 19, and is added into the heat storage tank through the heat storage medium inlet 16 on the top of the heat storage tank, and then all the heat collection tubes are filled. Since the closed end of the heat collection tube is lower than the open end, there is no heat in the heat collection tube Bubbles will form. With the continuous irradiation of sunlight, the temperature of the heat storage medium continues to rise, and the heat is stored in the heat storage tank. The water inlet 17 is connected through a pipe, so that cold water enters the heat storage tank, exchanges heat through the heat exchanger, and then flows out through the water outlet 15, so that hot water with uniform temperature can be obtained.
