Abstract: A fan frame with noise muffling structure includes a frame having a top and a bottom and defining a centered air flow passage that extends from the top to the bottom. The air flow passage has an air inlet and an air outlet formed on the top and the bottom, respectively. The frame further has a noise muffling zone in at least one area of the frame located between the air flow passage and an outer periphery of the frame. In the noise muffling zone, there is provided at least one noise muffling unit, which is located between the top and the bottom without communicating with the air flow passage. The noise muffling unit internally defines a hollow cavity, which is closed between but not extended through the top and the bottom. The hollow cavity isolates air flow noise and absorbs frame vibration and noise produced by the frame vibration.

Abstract: A series fan structure includes a series fan assembly and an assembling member. The series fan assembly has a first fan and a second fan. The first and second fans are correspondingly serially connected with each other. The first fan has a first fan frame defining a first receiving space. The second fan has a second fan frame defining a second receiving space. The assembling member is disposed between the first and second fan frames. The assembling member is formed with multiple straight-through perforations in communication with the first and second receiving spaces. The series fan structure improves the vibration and noise problem of the conventional series fan structure and is able to increase airflow volume.

Abstract: A series fan structure includes at least one first combining part and a series fan assembly, which has a first fan and a second fan mated with the first fan. The first fan has a first base and a lateral side, which together internally define a first passage. The first base is outwardly extended to form a plurality of a first supporting portions connected to the first lateral side. A first connecting space is defined among the first supporting portions and communicated with the first passage. The second fan has a second base and a lateral side, which together internally define a second passage, which is communicated with the first passage and the first connecting space. The first combining part is located in the first connecting space and connected to the first supporting portions and has a plurality of first holes communicated with the first and the second passage.
