The invention disclose is wall inner heat preservation structure for building, especially a fluid adjusting type inner heat preservation structure with multifunction for external heat preservation andinner thermoregulation and the making method, which includes a heat emission layer, a diversity water type plastic tubing net and an insulation layer, wherein, the diversity water type plastic tubingnet comprises two main tubes and a plurality of capillaries vertical coupling to the two main tubes with two ports communicated with the external heating or refrigerating system, characterized in that, the heat dissipation layer is composed of a double-layer thermal fin, and a plurality of capillaries is clamped between the double-layer thermal fin; wherein the space between the plurality of capillaries and the thermal fin coating the two sides is compactly sticked without air obstruct. One side of the insulation layer is sticked with the outside surface of the thermal fin, and the other sideis connected with the wall, which has light weight, thin thickness, even thermolysis, no noise, marked energy saving effect, and not only is suitable for the installation of the new building wall, but also for the heat preservation energy saving reconstruct of the old building, and easy to extend and actualize.
