Background

The existing solar water heater mainly comprises a non-pressure-bearing type and a pressure-bearing type. The water storage container of the non-pressure-bearing solar water heater is directly communicated with the solar heat collecting pipe, so that a user directly uses hot water heated by solar energy without an intermediate heat exchange link. Because the water storage container has no pressure, the water flow impact force is insufficient when the water storage container is used; in addition, because the antifreeze cannot be added into the water, the external water pipe connected with the solar heat collecting pipe may freeze in cold seasons. A water storage container (generally called as an inner container) of the pressure-bearing solar water heater is in circulating heat absorption coupling connection with a solar heat collecting pipe through a heat exchange structure. The inner container is not directly communicated with the solar heat collecting pipe, so that internal pressure can be provided, and water flow with strong impact force can be output; meanwhile, antifreeze can be added into the circulating heat transfer medium of the solar heat collecting pipe, so that freezing is avoided.

However, the pressure-bearing solar water heater in the prior art has the problems of low heat exchange speed and poor heat exchange effect.
