Volumetric heat exchange inner lining with electrical auxiliary heating

The utility model discloses a volumetric heat exchange inner lining with electrical auxiliary heating. The inner lining comprises a shell (15), an electrical heating core component (12) and a heat exchange core component (16), wherein the heat exchange core component (16) is provided with a cavity, a medium inlet pipe (20) and a medium outlet pipe (21); the electrical heating core component (12) mainly comprises a heat collection housing (10) and an electrical heating tube (11); the heat collection housing (10) is communicated with the shell (15) and surrounds the electrical heating tube (11); a water inlet of the water outlet pipe extends into a region surrounded by the heat collection housing (10). Integral one-step heat exchange is performed on the inner lining through the heat exchange core component, and secondary on-demand heating can also be performed on water flowing out from the inner lining through the electrical heating core component, so primary heat sources such as solar energy and a heat pump can be efficiently utilized, and the electric energy waste for secondary heating can also be effectively reduced.
