Embodiment Construction
[0028] To make the objectives, technical solutions and advantages of the present invention will become more apparent hereinafter in conjunction with drawings and embodiments of the present invention will be further described in detail. It should be understood that the specific embodiments described herein are merely for explaining the present invention, not to limit the present invention.
[0029] An outer rotor motor in the prior art, although the rotor is disposed outside of the stator, but it is still a separate output shaft when the output of the output, and the like also need to set a bearing structure between the housing and the rotor is achieved like the support structure of the rotor and / or blades, in order to overcome the foregoing between the motor and the rotor blades foreign difficult assembly problems, the present application provides a Figure 1 to 4 An outer rotor motor, the outer rotor motor comprises a rotor (a rotor located inside the housing 12, not shown in th...

The invention provides a fan assembly and heat exchange equipment. The fan assembly comprises an outer rotor motor and fan blades, the outer rotor motor comprises a rotor and a shell, the shell is fixed to the rotor, and fixing shafts are arranged on the shell; mounting holes are formed in the fan blades; and the fixing shafts can extend into the mounting holes to fix the fan blades and the outer rotor motor. According to the fan assembly and the heat exchange equipment, the mounting holes are formed in the fan blades, the mounting holes and the fixing shafts on the shell of the outer rotor motor can be installed in a matched manner, the problem that in the prior art, an outer rotor motor and fan blades are difficult to assemble is solved, meanwhile, guide structures and reinforcing ribs are arranged on the fan blades, a shaft sleeve assembly is not needed in the middle, the assembly efficiency of the centrifugal fan blades and the outer rotor motor is improved, the use cost of the outer rotor motor is reduced, and meanwhile, the fan blades are driven by the outer rotor motor, so that the noise is effectively reduced.
Description
Technical field [0001] The present invention relates to the technical field of air treatment equipment, in particular a fan and heat exchanger assembly. Background technique [0002] Conventional rotor motor comprising an inner rotor and an outer rotor motor two kinds of machine, since the inner rotor motor relatively simple to manufacture, lower cost, opposite to the outer rotor motor, the stator and rotor inside the external, relatively more difficult to manufacture, and convenient fitted with blades, such conventional machines are widely used patio inner rotor motor, the motor and fan uniaxial connection without using external rotor motor, but poor dynamic balancing of the inner rotor motor, the rotation shake up in poor stability , patio machine such poor reliability and a large noise. Inventive content [0003] In order to solve the conventional low internal rotor motor patio machine reliability and a large technical problem of noise, and to provide an outer rotor motor is ...
