Heat-storage solar water heater

Abstract

The invention discloses a heat-storage solar water heater, relating to a heat-storage solar water heater. The heat-storage solar water heater comprises an evacuated collector tube, a heat tube arranged in the evacuated collector tube, a water tank, a frame, a heat-storage tank and a heat exchange pipeline, wherein, the heat-storage tank which is stored with solid heat-storage materials in a sealing manner is provided with a plurality of holes at the lower part, the evacuated collector tube is arranged at the lower part of the heat-storage tank, the heat tube is arranged in the evacuated collector tube, the tip of the heat tube is contacted with the solid heat-storage materials in the heat-storage tank by the holes, and the heat tube and the holes are sealed by heat insulating pieces; the heat exchange pipeline is embedded in the solid heat-storage materials in the heat-storage tank; the lower parts of both ends of the water tank are provided with two connecting holes which are connected with the heat exchange tube so as to communicate with the water tank. Compared with the wall mounted water heater in the prior art, the outdoor part of the invention has greatly reduced weight and greatly improved installation reliability. After the water in the water tank is heated to a certain degree, a valve is closed, and the solid heat-storage medium still can store heat quantity, thereby being capable of heating more water.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a wall-mounted solar split water heater. Background technique [0002] It is difficult for residents of high-rise buildings to use ordinary solar water heaters. Some design and production units have provided a wall-mounted solar water heater for this purpose. The heat-collecting surface faces the sun and is hung outside the balcony as a whole. The water heaters of the users on the lower floor are hung outside the balcony of the users on the upper floor. This has brought about two problems. One is that the real estate is now private property. Although it has the nature of mutual use, it is very inconvenient for maintenance. The upper part of the building is very windy, and the frame, vacuum heat collecting tubes, and water tank of the ordinary wall-mounted water heater are all arranged outside the wall. When the water tank is fully loaded, the weight is heavy, and long-term use poses a saf...

This has brought about two problems. One is that the real estate is now private property. Although it has the nature of mutual use, it is very inconvenient for maintenance. The upper part of the building is windy, and the frame, vacuum heat collecting tube, and water tank of an ordinary wall-mounted water heater are all set outside the wall. When the water tank is fully loaded, the weight is heavy, and long-term use poses a safety hazard.
