Description

Sealed water tank

Technical Field

The utility model relates to a solar water heater equipment technical field, concretely relates to sealed water tank.

Background

The solar water heater is a heating device for converting solar energy into heat energy, and can heat water from low temperature to high temperature so as to meet the requirement of hot water in life and production of people. With the improvement of awareness of people on environmental protection, solar energy, a green energy source, is used more and more, and the most widely used solar water heater is embodied, and a water tank of the solar water heater is an important component of the solar water heater. The existing solar water heater is generally communicated with an inner container of a water tank through a plurality of heat collecting pipes so as to heat water in the water tank. The existing connection mode of the heat collecting pipe and the water tank liner is generally welded or directly connected through a sealing ring, the welding connection mode requires high production conditions, whether a person has hidden danger of water leakage, the sealing stability of the connection mode of the sealing ring is not high, and water leakage is easy to occur after long-time use. If the kneck of thermal-collecting tube and inner bag is if take place to leak water, water then can directly permeate the heat preservation between inner bag and the shell, influences the heat preservation effect of water tank, shortens the life of water tank, can lead to the rivers loss in the water tank again to influence people's water demand.
