Whole wall-mounted type solar water heater

Abstract

The invention discloses a whole wall-mounted type solar water heater. The whole wall-mounted type solar water heater comprises a water tank, and is characterized in that heat collection pipe brackets are fixed on two sides of the water tank respectively; a plurality of vacuum heat collection pipes, which are arrayed in an L shape and are communicated with the water tank, are transversely arranged on the heat collection pipe brackets on two sides; the water tank comprises a tank body and a tank cover; a cold water opening, a hot water opening, a water replenishing opening and an overflowing opening are formed in the tank body; a heat exchanger for communicated with the cold water opening and the hot water opening is arranged in the tank body; a water temperature and water level sensor is arranged at the upper part of the tank body or on the tank cover; an electromagnetic heater for heating the tank body is arranged on the front side or the rear side of the tank body. The whole wall-mounted type solar water heater is suitable for being used between upper and lower windows or a balcony in a south-facing vertical face wall of a building; the lighting area is large, the heat efficiency is high, the performance is stable, the maintenance is convenient and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of solar energy, in particular to an integral wall-mounted solar water heater. Background technique [0002] The overall wall-mounted solar water heater has become the new favorite of energy-saving buildings due to its compact structure, good heat absorption and heat preservation performance, convenient installation, and perfect overall effect. However, the original integral wall-mounted solar water heater has shortcomings such as small water tank capacity and difficult repair and maintenance after the stainless steel heat exchange tube breaks down. The overall wall-mounted solar water heater is installed on the south facade wall or balcony of the building. The best position of the south facade wall is the interval between the upper and lower windows. The distance between the upper and lower windows of modern buildings is generally about 1000mm. Due to the limitation of the interval height, the heat collect...

Problems solved by technology

However, the original integral wall-mounted solar water heater has shortcomings such as small water tank capacity and difficult repair and maintenance after the stainless steel heat exchange tube fails.

The overall wall-mounted solar water heater is installed on the south facade wall or balcony of the building. The best position of the south facade wall is the interval between the upper and lower windows. The distance between the upper and lower windows of modern buildings is generally about 1000mm. Due to the limitation of the interval height, the heat collecting area of ​​the heat collector is also limited. At present, the maximum heat collecting area of ​​the wall-mounted solar energy is about two square meters (15 58mm vacuum heat collecting tubes). Therefore, the water tank of the existing integral wall-mounted solar water heater The capacity is small and the water temperature is low, which cannot meet the needs of users; most of the existing integral wall-mounted solar water heaters use stainless steel heat exchange tubes for hot water operation, and the stainless steel heat exchange tubes are welded and sealed in the water tank. Once the heat exchange tubes leak , Maintenance is extremely troublesome. It takes time and effort to remove the solar water tank and send it to the factory for repair, which also increases the maintenance cost.
