Detailed Description

The heat exchange tube box of the energy saver of the present invention will be further described with reference to the accompanying drawings and specific embodiments.

Fig. 1 is a schematic top view of the heat exchange tube box of the energy saver of the present invention; FIG. 2 is a cross-sectional view F-F of FIG. 1; FIG. 3 is a cross-sectional view of K-K of FIG. 1; fig. 4 is a schematic view of the structure of the element 9 of fig. 1. In the figure, the heat exchange tube box of the energy saver comprises a water inlet collection box 4 and a water outlet collection box 1, wherein the water inlet collection box 4 is fixed on a bottom plate 6 and used for collecting cold water, the water outlet collection box 1 is used for collecting hot water, the water inlet collection box 4 is communicated with the water outlet collection box 1 through a heat exchange tube 2, stand columns 5 are arranged at four corners of the bottom plate 6, a joist 3 is transversely arranged between every two adjacent stand columns 5, the joist 3 is nine layers, the joist 3 is arranged on the stand columns 5 at equal intervals from upper end to lower end, the heat exchange tube 2 is arranged on the joist 3, a top plate 7 is arranged on the upper end face of the topmost heat exchange tube 2, front and rear sealing plates 8 and the top plate 7 are arranged on the front and rear sides of the heat exchange tube 2, a cylindrical heat exchange cavity 10 is formed by the bottom plate 6 in a sealing.
