In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a fan casing and motor housing's connection structure, includes the casing, the outside of casing is provided with the mount, the screw has been seted up on the mount, be provided with the connecting piece on the inside wall of casing, the connecting hole has been seted up on the connecting piece, install the pipeline on the inner wall of casing, placed the motor in the casing, the edge outer lane of motor is provided with the connecting block, the center of motor is provided with the pivot, the louvre has been seted up at the back of casing.

Preferably, the pipelines are internally provided with condensate which is in a circulating structure between the pipelines, and the pipelines are mutually connected.

Preferably, the number of the fixing frames is four.

Preferably, the connecting pieces are fixedly connected with the shell through welding, and the number of the connecting pieces is four.

Preferably, the number of the connecting blocks is four, and the connecting blocks correspond to the positions of the connecting pieces.

Preferably, the heat dissipation holes are distributed in an arc shape on the back of the shell, and the arc radian is the same as that of the shell.

Compared with the prior art, the beneficial effects of the utility model are that: this connection structure of fan housing and motor housing through the screw with mount and fan housing fixed connection, convenient dismantlement and installation, and the casing is inside to be provided with the connecting piece and to correspond the setting with the connecting block on the motor, fixes the motor firm in the casing, is equipped with the condensate in the pipeline of setting, cools down to the motor, and the casing back is provided with the louvre simultaneously, does benefit to the heat dissipation of motor for the operation that the motor can be better.
