Solar water tank with thermal insulating plate

The utility model provides a solar water tank with a thermal insulating plate, which comprises a tank body with a thermal insulating layer, a water inlet and a water outlet which are arranged on the bottom of the tank body. The utility model is characterized in that partition plates and a heat conducting pipe which is connected in parallel with a radiator are additionally arranged, wherein the water in the space of the tank body is transversally divided into a plurality of layers by the partition plates which are provided with water holes, the middle part of the heat conducting pipe is positioned in the tank body and is in the shape of a coil pipe, and a pipeline before entering the tank body is provided with a control valve. Because the inner space of the tank body is divided into a plurality of layers by the partition plates, each of the partition plates is provided with the water holes which are convenient for the water on upper layer to flow to the lower layer. When a part of water in the tank body is used and is not filled, the radiating area of hot water can be reduced by the partition plates, thereby, the thermal insulating function is played. When the water temperature in the tank body is not high in winter, the control valve on the heat conducting pipe can be opened to make the hot water in the radiator flow through from the inner part of the tank body. The radiator is used for heating the water in the tank body so as to ensure the temperature of the water in the tank body. The utility model has the advantages of simple structure and good using performance.
