The invention discloses a divided water tank device for an internal
heat exchanger of a split type
solar water heater.
Butt welding is carried out by utilizing an end
enclosure of a stainless steel
confined water bank inner bag; the end
enclosure is used as the
heat exchanger to play the role of a water tank partition board; the water tank is divided into independent divided cavities; the
heat exchanger is sealed with the inner bag of the water tank; the adjacent cavity bodies communicate with each other via draught tubes; the medium circulation and the medium supplement, namely unconfined running of the heat exchanging part, are carried out safely and reliably via an upper circulating
pipe and a heat collecting part; and the device can fully improve
heat energy transformation and reduce heat loss.
