Abstract
A dual-blade type cooling fan comprises bearings, a support, motors mounted on the bearings, magnet frames and fan blades, and is characterized in that the fan blades are formed by combining two or more curved blades with the same blade-type; and the curved fan blades with the same blade-type are respectively driven by a single motor or different motors. According to the utility model, the curved fan blades with the same blade-type are combined together, so that air volume and air pressure of the cooling fan are promoted, and the overall energy efficiency of the cooling fan is improved.
Description
[technical field]
The utility model relates to radiation fan, relates in particular to the radiation fan of integrated same modality blade.
[background technique]
Existing radiation fan generally is the flabellum for single shape curved surface, is subject to functional single impact, can't improving performance, and airflow pressure is the single motor control that is subject to only, and efficiency is good not.
[summary of the invention]
The utility model has proposed a kind ofly will just can promote the radiation fan of air quantity and blast under equal-wattage for above problem.
The technical solution of the utility model is: described bifolium radiation fan, comprise bearing, support, be installed in motor, magnet frame and fan blade on the bearing, it is characterized in that, described fan blade is that two kinds or two or more identical blade profile curved surface bucket combine, and the fan blade of described identical blade profile curved surface is driven by single or identical motor respectively.
The combination of the fan blade of described identical blade profile curved surface has two kinds, a kind ofly is that identical blade profile curved surface bucket is one-body molded or is combined on the same fan blade in conjunction with generating that another kind is that the fan blade with identical blade profile curved surface bucket is combined.
Two flabellums respectively upper and lower dislocation are sequentially arranged.
The beneficial effects of the utility model are: the fan blade of identical blade profile curved surface is combined, utilize upper and lower dislocation mode to arrange, but the wind that frontal lobe can be pressed down improves the efficiency of radiation fan integral body again through air quantity and the blast of posterior lobe pressurization heat radiation fan.
[description of drawings]
Fig. 1 is the utility model one example structure schematic representation;
Fig. 2 is the utility model structural representation.
Wherein: 1, the first fan blade; 2, the second fan blade; 3, the first magnet frame; 4, the second magnet frame; 5, the first motor; 6, the second motor; 7, support; 8, the second bearing; 9, clutch shaft bearing.
[embodiment]
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.
Embodiment 1:
Bifolium radiation fan as shown in Figure 1, holder part in the middle of comprising, two bearings have been installed respectively, be respectively clutch shaft bearing 9 and the second bearing 8, be installed on two bearings, respectively the first motor 5 and the second motor 6, between motor and fan blade, has a magnet frame, at the first motor 6 the first magnet frame 3 has been installed, at the second motor 6 the second magnet frame 4 has been installed, it is characterized in that, described fan blade is that two kinds or two or more identical blade profile curved surface bucket combine, the fan blade of described identical blade profile curved surface is driven by different motors respectively, and what install at the first magnet frame is the first fan blade 1, second fan blade 2 of installing at the second magnet frame.
Also the flabellum of identical blade profile curved surface can be incorporated on a slice flabellum, rely on single motor drive fan leaf.
The combination of the fan blade of described identical blade profile curved surface has two kinds, a kind ofly is that identical blade profile curved surface bucket is one-body molded or is combined on the same fan blade in conjunction with generating that another kind is that the flabellum with identical blade profile curved surface bucket is combined.Structure as shown in Figure 2 is exactly the fan that combines the blade formation of two kinds of identical blade profile curved surfaces on the single fan blade.
Two flabellums respectively upper and lower dislocation are sequentially arranged.
The beneficial effects of the utility model are: the fan blade of identical blade profile curved surface is combined, utilize upper and lower dislocation mode to arrange, but the wind that frontal lobe can be pressed down improves the efficiency of radiation fan integral body again through air quantity and the blast of posterior lobe pressurization heat radiation fan.
Claims (3)
1. bifolium radiation fan, comprise bearing, support, be installed in motor, magnet frame and fan blade on the bearing, it is characterized in that, described fan blade is that two kinds or two or more identical blade profile curved surface bucket combine, and the fan blade of described identical blade profile curved surface is driven by single or different motors respectively.
2. described bifolium radiation fan according to claim 1, it is characterized in that, the fan blade combination of described identical blade profile curved surface has two kinds, a kind ofly be that identical blade profile curved surface bucket is one-body molded or be combined on the same fan blade in conjunction with generating that another kind is that the fan blade with identical blade profile curved surface bucket is combined.
3. described bifolium radiation fan according to claim 2 is characterized in that two flabellums respectively upper and lower dislocation are sequentially arranged.
