Abstract
The utility model discloses a novel cooling fan, including motor and fan guard's cover, the surface of protecting the fan cover is equipped with the ventilation window, and the inside ventilation window grid that is equipped with of ventilation window, the ventilation window grid outside is equipped with the ventilation window blade that can open, and the ventilation window sets up with the slope of fan guard surface. Compared with the prior art, the utility model the advantage lie in: the utility model discloses be equipped with the ventilation window and the ventilation window blade that can open, enlarged cooling fan's heat dissipation scope, when the fan had big windward in front, under the wind-force effect, overcome the gravity that the ventilation window blade that can open produced, the ventilation window blade that can open is opened by oneself, and wind passes through the ventilation window, makes the ventilation of radiator increase, reinforcing radiating effect.
Description
Technical Field
The utility model relates to a cooling fan technical field specifically is a novel cooling fan.
Background
The cooling fan is a power device for providing air flow in the cooling system and has air suction and air blowing types.
The existing cooling fan is generally of an air suction type, is arranged behind a radiator and is applied to a cooling system of a mobile vehicle to dissipate and cool the radiator.
The defects in the prior art are as follows:
when a vehicle moves, due to the existence of windward wind, the fan air protection cover hinders air flow, air fluidity is poor, and heat dissipation of a cooling system is reduced.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome above technical defect, provide a can promote the fan volume of airing exhaust, promote the novel cooling fan of radiator heat dissipation volume.
In order to solve the above problem, the technical scheme of the utility model is that: a novel cooling fan comprises a motor, a fan and a fan cover, wherein a ventilation window is arranged on the surface of the fan cover;
the ventilating window is characterized in that a ventilating window grating is arranged inside the ventilating window, openable ventilating window blades are arranged on the outer side of the ventilating window grating, and the ventilating window and the surface of the fan protecting cover are obliquely arranged.
Further, the fan is fixed inside the fan guard through the planet carrier.
Furthermore, the openable ventilation window blade is connected with the ventilation window through a bolt.
Further, the opening angle of the openable ventilation window blade is smaller than 90 degrees.
Further, the inclination angle between the ventilation window and the wind protection cover is smaller than 90 degrees.
Compared with the prior art, the utility model the advantage lie in:
the utility model discloses be equipped with the ventilation window on the surface of protecting the fan housing, enlarged cooling fan heat dissipation range, the outside of ventilation window is equipped with the ventilation window blade that can open, when the fan had big windward in front, under the wind-force effect, has overcome the gravity that the ventilation window blade that can open produced, and the ventilation window blade that can open is opened by oneself, and wind passes through the ventilation window, makes the ventilation of radiator increase, reinforcing radiating effect.
Drawings
Fig. 1 is a rear view of the present invention;
fig. 2 is a right side view of the present invention;
fig. 3 is a diagram of the application of the present invention.
As shown in the figure: 1. A fan; 2. a wind protection cover; 3. a ventilation window; 4. a ventilation window grille; 5. an openable louver blade.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.
Examples
As shown in fig. 1, a novel cooling fan includes a motor, a fan 1 and a fan cover 2, a ventilation window 3 is disposed on the surface of the fan cover 2, and the ventilation window 3 can enhance the fan air discharge when the windward is large.
The inside ventilation window grille 4 that is equipped with of ventilation window 3, ventilation window grille 3 prevents that the ventilation window blade 5 that can open from being inhaled, plays the supporting role, ventilation window grille 4 outside is equipped with the ventilation window blade 5 that can open, when the fan has big windward, under the wind-force effect, overcome the gravity that ventilation fan blade 5 produced, ventilation fan blade 5 is opened, ventilation window 3 and fan guard 2 surface slope set up, when the fan does not have the windward or when the windward is less, because ventilation window 3 has certain inclination, under the influence of gravity and negative pressure, the ventilation window blade 5 that can open is closed.
As shown in fig. 1, the fan is fixed inside the wind guard cover by the carrier.
As shown in fig. 2, the inclination angle between the ventilation window 3 and the wind-protecting cover 2 is smaller than 90 °, when the radiator is not facing the wind or is facing the wind less, the ventilation fan blade 5 is closed under the influence of gravity and negative pressure due to the certain inclination angle of the ventilation window 3.
As shown in fig. 3, the openable louver blades 5 are connected with the louver 3 by bolts, and the openable louver blades 5 can be opened by themselves under the action of wind when the windward is strong.
As shown in fig. 3, the opening angle of the openable louver blades 5 is less than 90 ° under the influence of wind.
In a specific use:
the cooling fan is arranged behind the radiator, and the motor, the fan blades 1, the fan protection cover 2 and the ventilation window 3 form the cooling fan which is an air suction test fan.
When the radiator is not windward or windward is small, the motor and the fan blades 1 work to enable airflow to pass through the radiator, and the ventilation fan blades 5 are closed under the influence of gravity and negative pressure due to the fact that the ventilation window 3 has a certain inclination angle. The ventilation grille 4 prevents the ventilation fan blade 5 from being sucked in, and plays a supporting role.
When the radiator has big windward, under the effect of wind power, overcome the gravity that ventilating fan blade 5 produced, ventilating fan blade 5 opens, and wind passes through ventilation window 3, makes the ventilation of radiator increase, strengthens the radiating effect.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
