The utility model belongs to the technical field of communication equipment, and particularly relates to a noise reduction type microwave communication system based on quantum encryption, which comprises a main body, and sound absorption cotton plates for eliminating noise generated by the main body are arranged at the upper end and the lower end in a protection box. A sound-absorbing cotton plate is arranged in the protection box to wrap the main body, noise generated by the main body can be eliminated, a driving motor is further utilized to drive blades to rotate through a transmission belt to generate wind power to dissipate heat of the main body, the sound-absorbing cotton plate and the protection box can be combined for use, the functionality is high, and the situation that heat dissipation or noise reduction can only be conducted singly is avoided; the spring columns are arranged on the outer side of the fixing frame at equal intervals to be connected with the protection box, main bodies of different si
