The utility model relates to motor shell technical field especially relates to a split type extruded
aluminium heat dissipation shell structure of inner rotation motor, including the heat dissipation shell is combined by a plurality of small shell, the small shell one end all is provided with the clamping slot, and the small shell other end all is provided with the clamping strip, the utility model discloses a small shell on the clamping strip is installed to the inside of adjacent clamping slot in proper order, so that small shell can be in proper order circular distribution splicing into heat dissipation shell, so that heat dissipation shell whole is split type structure, and it is convenient to dismantle and install, so when heat dissipation shell appears damage, it is convenient to replace alone to the small shell of a place or a few places, and when
processing heat dissipation shell, can divide heat dissipation shell into a plurality of small shell and carry out split type
processing, then carry out combination again, so that when
processing can adopt small
tonnage extruded
aluminium equipment and process, more convenient, can reduce the
scrap rate and material production consumption.
