摘要： A guiding grid (1, 1b) is disclosed and includes plural circumferential elements (10, 10b) and plural radial elements (20, 20b). The circumferential elements (10) are disposed concentrically relative to a central axis (1), spaced apart from each other in a radial direction, and form different heights relative to a bottom surface (B). One of the circumferential elements (14) forms a top height (H) relative to the bottom surface (B), so that the circumferential elements (10) are divided into an outer-ring region (P) and a central region (C) in the radial direction. The circumferential elements (11, 12, 13) located in the central region (C) are increased in height relative to the bottom surface (B) along the radial direction. The circumferential elements (15, 16, 17, 18) located in the outer ring region (P) are reduced in height relative to the bottom surface (B) along the radial direction. The radial elements (20, 20b) are connected between each of two adjacent circumferential elements (10, 10b). At least one of the radial elements (20, 20b) is misaligned and discontinuous in the radial direction.

摘要： A centrifugal ceiling fan adapted to evenly ventilate and heat its surrounding area. The fan comprises a casing defining a top, a side, and a bottom. The air inlet is provided in the top and the air outlet comprises a first passage provided in the side and a second passage provided in the bottom, and a central dome for regulating the flow of air between the first passage and the second passage to a desired proportion. The fan comprises a centrifugal propeller having blades which are curved and have a variable width such that rotation of the centrifugal propeller causes air to be received from said air inlet and to be pushed from said air outlet in substantially all directions between the first direction and the second direction. The dome comprises a heat source for heating air pushed downward from the bottom. Whereby, unheated air is pushed sideways and heated air is pushed downward and for evenly ventilating and heating a room in which the centrifugal ceiling fan is installed.

摘要： An air-cooled heat exchange system includes a heat exchanger and an axial fan assembly. The heat exchanger has a heat exchange surface area. The axial fan assembly has a propeller-type impeller rotatably supported within an annular housing. The annular housing defines an air passageway from an air inlet end of the housing, across the impeller, and to an air outlet end of the housing. Rotation of the impeller within the annular housing causes air to flow into the air inlet end of the housing, along the air passageway, and out the air outlet of the housing. The axial fan assembly also has a wind-turning vane assembly extending beyond the air inlet end of the annular housing.

摘要： An obj ect is to provide a vehicle heat-exchange module capable of optimizing the whole of a stator blade that deflects a flow in the swirling direction produced by a cooling fan, thereby reducing the work performed by the cooling fan and eventually reducing the input power to the cooling fan, and to provide a vehicle having the vehicle heat-exchange module. According to the vehicle heat-exchange module (10), the stator blade (30) arranged on the downstream side of the cooling fan (16) is divided by an intermediate ring (31) into inner-circumference-side stator blade members (32A) and outer-circumference-side stator blade members (32B), and the number of the inner-circumference-side stator blade members (32A) for installation is made smaller than that of the outer-circumference-side stator blade members (32B), thus setting the pitch/chord ratio within an appropriate range at each of the inner circumference side and the outer circumference side. As a result, a flow in the swirling direction produced by the cooling fan (16) is efficiently deflected by the whole of the stator blade (30), thereby reducing the work performed by the cooling fan (16) and eventually reducing the input power to the cooling fan (16).
