Abstract
The cooling fan with refrigerating chip before the fan includes one fan comprising rectangular frame and one blade combination inside the rectangular frame and comprising one hollow cylindrical seat and blades around the seat; and one refrigerating chip before the fan seat. The refrigerating chip cools the air before the fan through absorbing heat, and the fan produces forced airflow of the cooled air to reach heat dissipating effect.
Description
Technical field
The present invention relates to a kind of fan assembly, particularly a kind of fan structure with cooling chip.
Background technique
Because the progress of science and technology now, so that the present electronic product of producing is not only lightening day by day on volume, on arithmetic speed, promote day by day simultaneously, comparatively speaking, electronic product is under working at high speed, the effect heat that is produced also is tending towards considerable, and therefore for electronic product can be operated under normal operating temperature, suitable heat dissipation becomes a considerable ring.
Particularly in computer main, because computer main is made up of different electrical assemblys, and be placed on same casing inside, but computer housing belongs to a kind of enclosed space, the heat that descends computer main inside to be produced at one time will be considerable, therefore for fear of too much heat build-up in casing inside, prior art just is provided with fan on electrical assembly, via forced draft that fan produced with the heat band arround electrical assembly, avoid the accumulation of too much heat and form temperature rising state, cooperate the fan of being located on the casing that hot blast is outwards detached simultaneously, wish to reach cool effect.
But the space of cabinet inside is limited, the forced draft that fan produced is subject to the space and constantly recycles, therefore the thermolysis that can produce is limited, therefore in order to improve the thermolysis of fan, prior art just is provided with a group or more cooling chip on fan, effect by cooling chip, produce heat exchange action and air temperature is reduced with the chip ambient air, by the forced draft effect that fan produced the air of low temperature is pumped away again, carried out thermolysis again.
Yet, general cooling chip is to be arranged at the fan rear mostly, so that fan blows the cold wind that cooling fan produced forward by the forced draft effect that flabellum produced, but because the cooling action of cooling chip often makes fan produce the frosting state too strongly and easily, cause fan to make moist on the contrary or circuit frozen, shortened the working life of fan and cooling chip, significantly have influence on the effect of fan heat radiation, become the not most desirable part of this heat dissipation.
Summary of the invention
At above-mentioned defective, main purpose of the present invention is to provide a kind of cooling fan of cooling chip being located at the fan front end, before described cooling chip is arranged at the exhaust outlet of fan front end, except the cooling action by cooling chip self produces cold wind and blows the distant place to produce the thermolysis at fan, simultaneously via forced draft that fan produced constantly by after blow forward, also avoid the strong excessively cooling action of cooling chip and influence the running of fan.
In order to achieve the above object, the invention provides a kind of cooling fan, described structure is based on fan body, described fan has the rectangle framework, described framework inside is provided with the flabellum group, described flabellum group comprises pedestal, described pedestal is hollow cylindrical, described pedestal outer periphery are provided with a plurality of fan leafs, on the front-end face of fan base, be provided with at least one cooling chip, by the cooling effect of described cooling chip, contained heat absorption in the air with the fan front end and form cool air, the forced draft that cooperates fan simultaneously and produced blows the air that forms the state of cooling forward.

In the accompanying drawing, the list of parts of each label representative is as follows:
Conducting plate 124 insulating trips 125
Embodiment
Fig. 1 is a perspective view of the present invention, and Fig. 2 is a structure plan view of the present invention, and Fig. 3 is a structure sectional view of the present invention.Fan structure of the present invention is mainly based on fan 1, and described in the present embodiment fan 1 is an axial fan.Described fan 1 further comprises rectangle framework 11, be provided with flabellum group 12 in the described framework 11, described flabellum group 12 comprises pedestal 121 and a plurality of fan leaf 122, wherein said pedestal 121 is a hollow circular cylinder, be used to be provided with the component that drive flabellum group 12 and rotate (this is known technology, thereby no longer superfluous words) in the pedestal 121.Described a plurality of fan leaf 122 is connected on the outer periphery of described pedestal 121; Outlet air end at described fan 1 is provided with at least one cooling chip 2, in the present embodiment, described cooling chip 2 is attached on the front-end face 123 of described pedestal 1, and described cooling chip 2 is a kind of thermoelectric semiconductor, can draw heat contained in the air and makes air cooling-down.The anode and cathode electrode cable 3 that is connected with cooling chip 2 forms with external power supply by the conducting plate 124 of being located at printed circuit board (PCB) on the pedestal 121 and pedestal 121 inside respectively and is electrically connected, anode and cathode conducting plate 124 in pedestal 121 inside utilizes insulating trip 125 to intercept simultaneously, shown in the sectional view of Fig. 3.
Therefore after above-mentioned assembly assembling is finished, when described cooling chip 2 comes into operation, cause after contained heat is absorbed by cooling chip 2 in the air arround the fan 1 front end exhaust outlet and the temperature of air is descended, form the cold wind state, the forced draft that cooperates described fan 1 to be produced simultaneously, drive the chilled air of fan 1 front end exhaust outlet and blow forward, to promote the radiating efficiency of described air cooling.In addition, because described cooling chip 2 is located on the front end exhaust outlet position of fan 1, the sustainable fan 1 of being subjected to rotates the wind-force that is produced and blows, reduction produced cold because of the cooling action of cooling chip 2 even formed the frosting phenomenon, and the circuit of avoiding fan 1 and cooling chip 2 makes moist and shortens working life of fan 1.
Fig. 4 is the structure plan view of another embodiment of the present invention.As can be seen, described cooling chip 2 on the front-end face 123 that is arranged at above-mentioned pedestal 121, also at least one cooling chip 2 can be set on the preceding blade face of a plurality of fan leafs 122.In the present embodiment, a cooling chip 2 is located on the single fan leaf 122, utilize electrode cable 3 to be electrically connected mutually with external power supply simultaneously with the conducting plate 124 of pedestal 121 inside, therefore work as the forced draft that fan 1 running is produced, the formed cool air of cooling chip 2 actions is blowed forward, finishing its thermolysis, also avoid the cold excessively frosting phenomenon that produces of cooling chip 2 simultaneously and influence the running of fan 1.
In addition, fan 1 is except can being that described fan 1 also can be a blower fan as shown in Figure 5 the above-mentioned axial fan.On described a plurality of fan leafs 122, be provided with at least one cooling chip 2, four cooling chips 2 are set among this figure, when fan 1 operates the forced draft that is produced, the formed cool air of cooling chip 2 effects is blowed forward, improve existing thermolysis to form, the forced draft that cooperates fan 1 to rotate simultaneously to be produced is up to blowing described cooling chip 2, avoids described cooling chip 2 supercooling and produces the frosting phenomenon.
The above is the preferred embodiments of the present invention only, is not so promptly limits claim of the present invention, and every equivalence of doing according to claim of the present invention and description changes or modifies, and all should be included in the claim of the present invention.
