Example implementations relate to a fan module. The fan module may include an outer impeller having a first plurality of radial blades arranged between an inner circumference of the outer impeller and an outer circumference of the outer impeller. The outer impeller may be rotatable about a first axis of rotation. The fan module may include an inner impeller having a second plurality of radial blades, the inner impeller disposed within the inner circumference of the outer impeller and rotatable about a second axis of rotation.

Methods and systems are provided for an adjustable diffuser of a turbocharger compressor. In one example, a compressor includes a diffuser formed in a compressor housing downstream of an impeller of the compressor, the diffuser including guide blades mounted on a rotatable annular support of the diffuser. Further, an engine controller may adjust rotation of the annular support based on one or more engine operating conditions.

A centrifugal compressor, including: a housing, the housing including: an inlet, a flow channel, an impeller outlet, and an air diffusing channel; a centrifugal impeller disposed inside the housing; a rotating wall, the rotating wall including a front cascade; and a rotating disc, the rotating disc including a rear cascade. The impeller outlet is disposed adjacent to a rear part of the centrifugal impeller and is connected to the flow channel via the air diffusing channel. The rotating wall is disposed between the centrifugal impeller and the housing. The front cascade is disposed inside the front part of the rotating wall and is connected to a dynamic driving device. The rotating disc is disposed inside the housing adjacent to the air diffusing channel and is in a rigid connection with the rotating wall.

A blower is formed with multiple sets of rotatable rings of blades coupled to each other. Multiple inlet rings are correspondingly coupled to the multiple sets of rotatable rings of blades. In one embodiment, the blades may be forward facing blades and include a volute to accomplish pressure recovery. In further embodiments, the blades are backward facing. Such backward facing blades are designed to provide a static pressure rise. In some embodiment, three or more rings of blades with corresponding inlet rings are utilized.

A blower having a plurality of impellers is described. The blower has two driving devices and two impellers respectively mounted on the two driving devices. The blades of the two impellers, which are radially or axially disposed, are overlapped so as to enhance the heat-dissipating efficiency of the blower.
