a PTC heater mounting structure of an automobile comprises a PTC heater fixedly mounted on a front wall plate through a mounting bracket, the mounting bracket and the PTC heater are fixedly connected through a detachable structure, the mounting bracket and the front wall plate are also fixedly connected through a detachable structure, a middle channel is arranged at the lower end of the front wall plate, the mounting bracket extends outwards from the inside of the middle channel and then upwards, and a triangular structure is formed through the front wall plate; the PTC heater is fixed to the upwardly extending section of the mounting bracket. The mounting bracket is fixedly connected with the front wall plate through the two sections of extension structures, and a triangular stable supporting structure is formed through the front wall plate, so that the PTC heater is stably and reliably fixed on the front wall plate; the PTC heater is fixed on the upward extending section, so that the arrangement of other parts of the cab is facilitated, and the maintenance, the maintenance and the disassembly are facilitated.

Further, both ends of the mounting bracket are composed of a first fixing end and a second fixing end, and the mounting bracket is fixed on the dash panel through both ends. The mounting bracket is fixedly connected with the first fixed end and the second fixed end at two ends, so that mounting space can be provided for the heater to the greatest extent, and the structure of the front wall plate is fully utilized to mount and fix the clamping.

Furthermore, a first reinforcing plate is arranged between the first fixed end and the front wall plate, and the first reinforcing plate is welded at the position of the cover plugging hole of the front wall plate. The first reinforcing plate is welded at the plugging hole of the front wall plate with the plugging hole, so that the plugging cover is omitted, the rigidity of the front wall plate is enhanced, and the stability of the PTC heater mounting structure is improved. The front wall plate of the gasoline car with the cover blocking hole is directly adopted, and the special production of independent die sinking is not needed, so that the manufacturing cost is reduced.

Further, a second reinforcing plate is arranged between the second fixed end and the front wall plate, the second reinforcing plate is welded on the front wall plate, and the middle channel is formed on the second reinforcing plate. To enhance the stability of the PTC heater mounting structure by utilizing the high rigidity characteristic of the formed middle passage member.

Furthermore, the first reinforcing plate and the second reinforcing plate are provided with at least two positioning holes. The welding position of first reinforcing plate and second reinforcing plate is fixed a position to the locating hole, improves the position precision of the two welding on preceding bounding wall.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that: the PTC heater mounting structure is simplified, and the mounting stability of the PTC heater is improved.
