Description

Composite wall-mounted solar water heater

The utility model relates to a composite wall-mounted solar water heater which can be adapted to the installation of a high-floor or special structure building, and belongs to the technical field of solar water heaters.

Most of the existing wall-mounted solar water heaters separate the water tank and the heat collector, and realize heat collection through convection or passive circulation. Thermal efficiency, so the installation is complicated and the quality is not stable. In addition, this kind of structure has low pressure bearing capacity, difficulty in heat preservation, and high failure rate.

The purpose of this utility model is to provide a composite wall-mounted solar water heater, which can overcome the above-mentioned shortcomings. The main heat collector and water storage part of the water heater are combined into one body, that is, a pressure-bearing metal liner is installed in the super-large all-glass vacuum tube liner of the heat collector as the water storage tank of the water heater, and the heat is absorbed and discharged through the all-glass vacuum heat collection tube. Pass it to the metal liner to heat the water in the liner. The heat collector and the concentrating device are fixed on the bracket through the barrel bracket. The bracket can be directly connected to the vertical plane building. The concentrating reflector is set outside the heat collector Increase the heat collecting surface. When taking water, you only need to open the valve of the water outlet pipe, and the cold water will be replenished automatically. The operation is convenient and reliable, and the automatic function of the solar water heater can be realized.

The purpose of this utility model is achieved in that the all-glass vacuum heat collecting tube (1) is sleeved on the outside of the pressure-bearing inner container (2). The heat collecting tube is U-shaped, with a thermal insulation cover (7) in the middle; a sandwich (9) is formed between the inner wall (5) of the vacuum heat collecting tube (1) and the pressure inner tank (2), and a heat conducting medium ( 20), the inner tank (2) is provided with a water inlet pipe (4) and a water outlet pipe (3); a sealing ring (8) is installed between the insulation cover (7) and the vacuum heat collecting pipe (1), and the water outlet pipe (21) Connect with valve (19).

The liner (2) is connected with the heat insulation pad (15) with bolts (12), the bottom of the barrel holder (12) is fixed on the heat insulation pad (15) with bolts (14), and the reflector (17) and the protective net (10 ) are connected together, and are sleeved on the outside of the vacuum heat collecting tube (1) by elastic clips (11), and the barrel holder (12) is fixed on the support (18) with bolts (16).

The structure of the composite wall-mounted solar water heater is described in detail in conjunction with the accompanying drawings:

From Figure 1, the all-glass vacuum heat collecting tube (1) is set outside the pressure-bearing inner tank (2), the all-glass vacuum heat collecting tube (1) is U-shaped, and there is an insulating cover (7) in the middle of the heat collecting tube (1), An interlayer (9) is formed between the inner wall (5) of the vacuum heat collecting tube (1) and the pressure-bearing liner (2), and there is air, heat conducting fins or other heat conducting medium (20) in the interlayer (9); the liner ( 2) A water inlet pipe (4) and a water outlet pipe (3) are arranged on the top, and a sealing ring (8) is arranged between the insulation cover (7) and the vacuum heat collecting pipe (1). The water outlet pipe (3) is connected with the valve (19) by the water outlet pipeline (21) again. The inner wall (5) of the vacuum heat collecting tube (1) is coated with a selective absorption film (6), which can absorb radiant heat.

By Fig. 2, above-mentioned heat-collecting part is affixed above the support (18) with bolt (16) by bucket holder (12), and the bottom of bucket holder (12) is affixed to heat insulation pad (15) with bolt (14) again. This insulation pad is also connected with bolt (12) with liner (2), and reflector (17) is connected together with protective net (10), is sleeved on the outside of vacuum heat collecting tube (1) by elastic clip (11).

When the water heater is in use, water will be filled earlier, and the valve (19) on the water outlet pipe (3) is opened earlier, and tap water just enters from the water inlet pipe (4), and promptly closes the valve (19) until the water outlet pipe (3) has water to flow out; When the sun radiates, the selective absorption film (6) on the inner wall (5) of the all-glass vacuum heat collecting tube absorbs heat, and transfers heat to the pressure-bearing liner (2) through the heat-conducting medium (20) in the interlayer (9). The cold water in the inner bag (2) is heated; as long as the outlet pipe valve (19) is opened during use.

Compared with the prior art, the composite wall-mounted solar water heater has the following advantages: 1. The water tank and the liner are placed in the heat collector (all glass vacuum heat collecting tube) to directly absorb heat, reduce thermal resistance, and have high thermal efficiency. 2. There is no circulation pipeline and it is insulated by high vacuum and anti-reflection layer, so the heat loss is small. 3. The liner is made of stainless steel with δ=0.8mm～105mm, and has two nozzles with high pressure bearing capacity. 4. The whole machine is light in weight, less components, easy to install. 5. The installation angle of the reflective arc can be adjusted arbitrarily according to the local latitude.
