Abstract

The utility model discloses a long service life type LED (Light Emitting Diode) cooling fan which comprises an outer frame and fan blades. A bearing seat is arranged on the outer frame; a bearing is mounted on the bearing seat; the fan blades are mounted on the bearing through a central spindle; an oil-guiding and pressure-forming groove is formed in the inner wall of the bearing; the two ends of the bearing are sealed through end covers. The long service life type LED cooling fan efficiently avoids heat generation caused by mutual friction between the central spindle and the bearing, prevents dust from entering into the bearing and prevents oil leakage, greatly improves the service life and the malicious environment adaptability of the cooling fan, is very durable, and is suitable for cooling an LED.

Description

Long-life type LED cooling fan

Technical field

The utility model relates to blower fan technical field, especially a kind of long-life type LED cooling fan.

Background technique

For cooling fan, its structure must relate to fan shaft core and bearing, existing fan shaft core and bearing contact when relative movement, produce frictional heat energy and friction noise, and dust enters in bearing and oil leakage goes out, between axle core and bearing, produce in the running heat energy and make oil evaporation and loss, thereby have influence on the working life of cooling fan.

Model utility content

The purpose of this utility model is to provide a kind of axle core and mutual frictional heat of bearing avoided, and prevents that dust from entering bearing and oil leakage goes out, the long-life type LED cooling fan that the life-span is long.

For achieving the above object, the technological scheme that the utility model adopts is: a kind of durable type LED cooling fan, comprise housing, flabellum, on housing, be provided with bearing support, bearing is installed on bearing support, flabellum is arranged on bearing by axle core, is provided with Oil Guide builds pressure groove at the inwall of bearing, at the two ends of bearing, passes through end bracket enclosed.

Preferably, to build and press groove be man type groove to described Oil Guide.

Preferably, described Oil Guide is built the two ends up and down of pressing groove to be positioned at bearing inner wall.

Preferably, the internal diameter of described bearing intermediate section is greater than and Oil Guide is set builds the internal diameter of pressing groove position, has effectively avoided contacting of bearing and axle core while pressing building.。

The utility model adopts after said structure, by the inwall at bearing, Oil Guide is set and builds pressure groove, and by end cap sealed at both ends by bearing, between axle core and bearing, produce so a kind of oil film pressure during fan running, pressure is built in generation, axle core and bearing are kept apart completely, do not contact, thereby make it not produce frictional heat energy and friction noise, sealing by end cap simultaneously also can prevent that dust from entering with oil leakage, during due to running, between axle core and bearing, do not produce heat energy, structure also prevents self evaporating and loss of oil, reaches long-life object.

Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:

Fig. 1 is the utility model exploded view;

Fig. 2 is the installation diagram of this practical axle core and bearing;

Fig. 3 is the structural drawing of bearing.

In figure: 1 housing, 2 flabellums, 3 bearing supports, 4 bearings, 5 axle cores, 6 Oil Guides are built pressure groove, 7 end caps.

Embodiment

Shown in Fig. 1,2 and 3, long-life type LED cooling fan of the present utility model, comprise housing 1, flabellum 2, on housing 1, be provided with bearing support 3, bearing 4 is installed on bearing support 3, flabellum 2 is arranged on bearing 4 by axle core 5, is provided with Oil Guide builds and press groove 6 at the inwall of bearing 4, at the two ends of bearing 4, by end cap 7, seals.In the present embodiment, Oil Guide is built and is pressed groove 6 for man type groove, and Oil Guide is built the two ends up and down of pressing groove 6 to be positioned at bearing 4 inwalls.The internal diameter of bearing 4 intermediate sections is greater than the internal diameter that Oil Guide is built pressure groove 6 positions is set.

The utility model is built pressure groove 6 by special-purpose Oil Guide is set at bearing 4 inwalls, during fan running, between axle core 5 and bearing 4, produce a kind of oil film pressure, pressure is built in generation, and axle core 5 and bearing 4 are kept apart completely, does not contact, thereby make it not produce frictional heat energy and friction noise, center-side sealing at end cap 7, prevents that dust from entering with oil leakage, and during due to running, axle core 5 and 4, bearing do not produce heat energy, structure also can prevent self evaporating and loss of oil, reaches long-life object.

Product of the present utility model has special-purpose wind guiding structure and mounting structure in use, prevents that wind from refluxing, and has strengthened air output, thereby has strengthened the radiating effect of LED lamp, reaches and strengthens the LED lamp effect in working life.And between selecting, the torque force of motor and air quantity find a rational equinoctial point, do not affecting under the radiating effect prerequisite of LED lamp, strengthen the torque force of product, thereby product can be used in worse environment, strengthened its working life and adaptive capacity to environment.

The above is preferred implementation of the present utility model; certainly can not limit with this interest field of the utility model; should be understood that; for those skilled in the art; the technical solution of the utility model is modified or is equal to replacement, do not depart from the protection domain of technical solutions of the utility model.
