Description

Compact water tank

Technical Field

The utility model relates to a solar water heater field, concretely relates to compact water tank.

Background

At present, solar water heaters are widely used in household life of residents, and the compact water tank in the market still occupies a large area. This type of water tank absorbs solar heat through full glass vacuum tube heat absorption coating, and the inside water of heating vacuum tube conducts heat through the rivers circulation with the box inside. In order to ensure the hot water output rate under the condition of insufficient solar radiation, 80 percent of compact water heaters are provided with an auxiliary heat source electric heating rod. After the electric heating rod is used for a long time, more water scales (calcium carbonate) can be accumulated on the surface of the electric heating rod and the local part of the metal inner container, and the phenomenon is more obvious in areas with harder water quality. The presence of these scales corrodes the electric heating tube and hinders heat conduction, so that the electric heating tube itself is damaged due to an excessively high temperature.

At present, the main solving measures are as follows: 1. the descaler purifies water. 2. The surface of the electric heating pipe is provided with a scale-proof coating. 3. The surface load of the electric heating is reduced, and the service life of the electric heating pipe of the water tank is relatively prolonged. 4. The liner discharges sewage or the electric heating flange plate is detached to discharge sewage. The cost of the electric heating pipe of the water tank can be increased by the first 3 measures; the measure 4 can clean the electric heating tube, but the operation steps are more, the time is too long, and the operation is more troublesome.
