Abstract
The utility model relates to a novel heat-radiation fan, which comprises a fan blade component and a motor; a metal motor seat is arranged outside the motor; a plastic outer shell is fixed outside the metal motor seat; the metal motor seat is provided with a transverse baffle plate and a vertical baffle plate; the central position of the transverse baffle plate is provided with a motor fixed projection block; the plastic outer shell comprises a shell fixed bracket and an inner supporting shell; four reinforced bars are arranged between the outer shell fixed bracket and the inner supporting shell. The utility model provides a novel heat-radiation fan with good heat radiation effect, long service life and low manufacturing cost; since the plastic outer shell is adopted to be fixed externally, and a metal motor seat is arranged at the bottom of the motor, the problems of the prior art that the heat radiation effect is poor, the service life is short and the manufacturing cost is high are resolved, thereby having strong creativity and practicability, so that the market prospect is promising.
Description
Technical field
The utility model relates to a kind of fan, particularly a kind of radiation fan that is used on the mechanical part.
Background technique
At present, this radiation fan in the prior art, some is that plastics are made all on housing, shell and the inside motor cabinet are one, by the injection moulding once-through, easily manufactured like this, processing technology is few, processing cost is low, it is not fine that but this mechanism causes radiation effect of motor, particularly in motor bottom, if temperature is too high, plastics are easy to distortion even are melted, and have so just shortened the working life of fan; Also some is that housing all adopts metal formings such as aluminum alloy to make, the fan long service life of this structure, but waste material, and weight is big, is inconvenient to install and use, and has increased manufacture cost greatly.
The model utility content
For solving the problem that radiation fan radiating effect of the prior art is poor, working life is short and manufacture cost is high, provide the heat sinking fan of a kind of good heat dissipation effect, long service life and low cost of manufacture.
For addressing the above problem, heat sinking fan of the present utility model comprises a Blower Plate Assembly and a motor, it is characterized in that: the described metal motor cabinet that also is provided with outside motor, the described plastic casing body of also fixing outside the metal motor cabinet.
Heat sinking fan of the present utility model also comprises and has a following technical characteristics:
Described metal motor cabinet has a transverse baffle and a vertical baffle plate, and described central position at transverse baffle is provided with a motor fixed lobe piece.
Described plastic casing body comprises support shell in a shell fixing frame and, between shell fixing frame and interior support shell, there are four stiffening ribs to be connected, support shell has a horizontal shade shape block that matches with the transverse baffle of metal motor cabinet in the horizontal in described, on vertical a vertical block that matches with the vertical baffle plate of metal motor cabinet is arranged.
The holder part of heat sinking fan of the present utility model is provided with a metal motor cabinet owing to adopted the plastic casing body at outer fixing in motor bottom, has increased radiating effect so on the one hand, has also saved material on the other hand.
Description of drawings
Below in conjunction with the drawings and specific embodiments a kind of heat sinking fan of the present utility model is described further:
Fig. 1 is the perspective view of a kind of heat sinking fan of the present utility model;
Fig. 2 is the plan view of a kind of heat sinking fan of the present utility model;
Fig. 3 is the B-B sectional view of a kind of heat sinking fan of the present utility model.
Embodiment
As shown in figures 1 and 3, heat sinking fan of the present utility model comprises a plastic casing body 10, a metal motor cabinet 20, a Blower Plate Assembly 30 and a motor 40.
As shown in Figure 1 to Figure 3, Blower Plate Assembly 30 and motor 40 are known technology, can buy easily on market, no longer are further described here.Plastic casing body 10 is used for fixing and the entire heat dissipation fan is installed, plastic casing body 10 has two identical shell fixing frames 1 up and down, on shell fixing frame 1, have four equally distributed installation tapped holes 5, tapped hole 5 is installed is used for fixing and radiation fan is installed.In plastic casing body 10, has support shell in, interior support shell has a horizontal shade shape block 2 in the horizontal, on horizontal shade shape block 2, be distributed with two and be used to install the radius tapped hole 3 that motor is used, radius tapped hole 3 is mainly used in to be installed and fixed electrical machinery 40, and interior support shell has a vertical block 4 on vertical.Have four stiffening ribs 6 to be connected and fixed between interior support shell and shell fixing frame 1, wherein have a motor lines to go out wire casing 7 on the stiffening rib 6, motor lines goes out the electric wire that wire casing 7 is used to place motor.
As shown in Figure 1 to Figure 3, metal motor cabinet 20 has a transverse baffle 21 and a vertical baffle plate 22, and a motor fixed lobe piece 23 is set in the central position of transverse baffle 21.Transverse baffle 21 on the vertical direction with interior support shell on horizontal shade shape block 2 match and merge by laterally shade shape block 2 is fixing.Vertical block 4 in vertical baffle plate 22 nestles up on the support shell, whole metal motor cabinet 20 is tightly fixing by interior support shell.Motor fixed lobe piece 23 is used for fixing motor 40, also is lined with one deck pad 50 at metal motor cabinet 20.Because plastic casing body 10 adopts the plastics once-through to make, and has so just reduced processing technology, reduces cost, weight also alleviates greatly, and convenient the installation is provided with a metal motor cabinet 20 in addition on motor 40, just make that heat dissipation problem is resolved, thereby increased working life.
, but should be understood that under the situation that does not break away from relevant protection domain defined by the claims that those skilled in the art can make change and/or revise according to embodiment of the present utility model describing the present invention property and nonrestrictive description.
