A first outer bolt is disposed on the first rib, a second outer bolt is disposed on the second rib, and a third and fourth inner bolt are disposed on the flat plate. The copper water pipe is spirally coiled and includes at least two U-shaped units. Each U-shaped unit includes a first straight pipe section, a first arc-shaped pipe section, and a second straight pipe section. Adjacent U-shaped units are connected by the second arc-shaped pipe section. An inner hollow space is formed between the first and second straight pipe sections. The inner wall of the first arc-shaped plate is adapted to the outer wall of the first straight pipe section, and the inner wall of the second arc-shaped plate is adapted to the outer wall of the second straight pipe section. The third and fourth inner bolts pass through the inner hollow space to fix the aluminum profile plate, the copper water pipe, and the cast aluminum heating assembly together. The first and second outer bolts fix the aluminum profile plate, the copper water pipe, and the cast aluminum heating assembly together from both sides of the copper water pipe.

[0006] Furthermore, a hollow space is provided between the first straight pipe section and the second straight pipe section of two adjacent U-shaped units of the copper water pipe, and the cast aluminum heating component is installed inside the hollow space.

[0007] Furthermore, the cast aluminum heating assembly is formed by die casting at least two heating rods. The cast aluminum heating assembly is generally I-shaped with two inner arcs on both sides. The inner wall of the inner arc of the cast aluminum heating assembly is adapted to the outer wall of the first straight pipe section and the second straight pipe section.

[0008] Furthermore, one end of the copper water pipe is the water inlet, and the other end is the water outlet, with both the water inlet and the water outlet in the same direction.
