[0024] The PTC mounting plate 2 is welded inside the mounting frame 1, enabling the PTC mounting plate 2 to overlap in the vertical direction, reducing the overall floor area. At the same time, welding can also improve the overall connection strength and reduce the risk of fracture.

[0025] There are side plates 6 connected to the mounting frame 1 on both sides of the PTC mounting plate 2, increasing the welding area and connection strength through the side plates 6.

[0026] There are kidney-shaped holes 7 on the PTC mounting plate 2. The PTC 11 is fixed on the PTC mounting plate 2 through the kidney-shaped holes 7.

[0027] There is an intercooler 8 on the extension plate 3. In this way, the intercooler 8 and PTC 11 can overlap on the same vertical plane, effectively reducing the overall floor area and solving the problem of insufficient installation space when laid flat.

[0028] There is a support plate 9 at the end of the extension plate 3. There is a water pipe 10 on the intercooler 8, and the water pipe 10 is placed on the support plate 9. The support plate 9 is used to support the water pipe 10, reducing the risk of fracture at the connection between the water pipe 10 and the intercooler 8.

[0029] There is a PTC 11 on the PTC mounting plate 2, and there is a wire harness 12 on the PTC 11. The wire harness 12 is fixed on the side of the mounting frame 1 for convenient installation.
