In the prior art, usual blower fan is all support by shell, and wind leaf is arranged in shell, and this kind of blower fan gas fluidity is poor, and then causes radiating effect poor, and the design of wind leaf is perfect not, causes heat radiation unreasonable structure.
Practical novel content
The utility model is intended at least solve one of the problems of the prior art.
The purpose of this utility model is to propose a kind of heat transmission blower fan.
Heat transmission blower fan according to embodiment of the present utility model, comprising:
Body, described body comprises salient and planar portions;
Wind leaf, described wind leaf is D structure, and the lower surface of described wind leaf is oar shape, and narrow one end is near described salient, and what the upper surface of described wind leaf had an opposition near one end of described salient is two scarp of 4 degree with vertical plane angle; With
Support portion, described support portion hides the planar portions away from described salient, and is connected to the surface, side of described salient.
With support portion, blower fan is supported, and support portion does not hide body completely, and then the non-supported portion of the wind leaf being arranged at surface, body salient side hides, fit in the wind leaf of three-dimensional moulding again, hot blast can be made from dispatch from all directions, gas fluidity is strengthened, it is to increase the heat dispersion of blower fan.
According to an embodiment of the present utility model, the circumference that described wind leaf is radial is uniformly distributed in the multiple of surface, described salient 11 side.
According to an embodiment of the present utility model, described wind leaf is 12.
According to an embodiment of the present utility model, described wind blde pitch from the height on surface, described salient side higher than the height of described support portion apart from surface, described salient side.
According to an embodiment of the present utility model, the material of described wind leaf is aluminium.
According to an embodiment of the present utility model, described support portion is split structure, comprises the first support portion and the 2nd support portion, described first support portion and the 2nd support portion socket connection.
According to an embodiment of the present utility model, described support portion is provided with the scarp that surface, the side with described salient becomes 60 degree of angles to the place of connecing.
According to an embodiment of the present utility model, described first support portion and the 2nd support portion, all there is the scarp becoming 85 degree of angles with described planar portions.
According to an embodiment of the present utility model, described salient and described planar portions are one-body molded, and described body is reversed convex type.
Accompanying drawing explanation
The following drawings is only intended to be done by the utility model schematic description and interpretation, does not limit scope of the present utility model. Wherein:
Fig. 1 is the utility model example structure schematic diagram;
Fig. 2 is the utility model embodiment sectional view.
In figure: 1-body, 11-salient, 12-planar portions, 2-wind leaf, 3-support portion, 31-first support portion, 32-the 2nd support portion.
Embodiment
Below in conjunction with drawings and Examples, set forth the utility model further. In the following detailed description, only some one exemplary embodiment of the present utility model is described by the mode of explanation. Undoubtedly, the those of ordinary skill of this area is not it is to be appreciated that when deviateing spirit and scope of the present utility model, it is possible to described embodiment revised by various different mode. Therefore, accompanying drawing and description are being explanation property in essence, instead of for limiting the protection domain of claim.
As shown in Fig. 1 to 2, according to the heat transmission blower fan of the utility model embodiment, comprising:
Body 1, body 1 comprises salient 11 and planar portions 12;
Wind leaf 2, wind leaf 2 is D structure, and the lower surface of wind leaf 2 is oar shape, and narrow one end is near salient 11, and what the upper surface of wind leaf 2 had an opposition near one end of salient 11 is two scarp of 4 degree with vertical plane angle; With
Support portion 3, support portion 3 hides the planar portions 12 away from salient 11, and is connected to the surface, side of salient 11.
With support portion, blower fan is supported, and support portion does not hide body completely, and then the non-supported portion of the wind leaf being arranged at surface, body salient side hides, fit in the wind leaf of three-dimensional moulding again, hot blast can be made from dispatch from all directions, gas fluidity is strengthened, it is to increase the heat dispersion of blower fan.
Further, in order to make hot gas have better mobility, good heat dissipation effect, the circumference that wind leaf 2 is radial is uniformly distributed in the multiple of surface, salient 11 side.
Further, ensureing the object simultaneously reaching saving material of radiating effect the best, wind leaf 2 is 12.
Further, the height of wind leaf 2 apart from surface, salient 11 side is higher than the height of support portion 3 apart from surface, salient 11 side.
Further, in order to make intensity height, the pressure-bearing property of wind leaf good, the material of wind leaf 2 is aluminium.
Further, in order to make support portion 3 may be used for the support of the fan body to different diameter, support portion is set to split structure, comprise the first support portion 31 and the 2nd support portion 32, first support portion 31 and the 2nd support portion 32 socket connection, be convenient to make the diameter after the connection of the first support portion 31 and the 2nd support portion 32 adjustable.
