Description

Technical Field

[0001] The utility model relates to the technical field of heat preservation water tanks, in particular to a novel heat preservation water tank for a heating system. Background Art

[0002] The water tank of a solar water heater is one of the main components of a solar water heater. It is a device for storing hot and cold water. It has good thermal insulation performance, so it is also called an insulated water tank. The amount of melt water, thermal insulation performance, shape, structure and material selection of the insulated water tank will directly affect the performance and operation of the solar water heater. The existing insulated water tank generally has an inner tank. The lower part of the inner tank is connected to the vacuum collector tube for heat exchange, and the upper part of the inner tank is used to store hot water after heat exchange. There is no obvious separation point between cold water and hot water, and the heat exchange of water is always ongoing. This results in a decrease in the heat exchange capacity of the vacuum collector tube when there is no sunlight or the light is weak, and the temperature of the hot water in the insulated water tank will drop rapidly, which cannot meet normal use. In addition, due to the long-term use of the insulated water tank, the inner tank tank and the inside of the vacuum collector tube are prone to scaling, which not only reduces the heat conversion efficiency of the vacuum collector tube, but also affects the thermal insulation performance of the inner tank tank.
