Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation devices, in particular to a motor for a heat dissipation fan. Background Art

[0002] An electric motor (commonly known as a "motor") is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. It is divided into electric motors (symbol M) and generators (symbol G). The working principle of a DC generator is to convert the alternating electromotive force induced in the armature coil into a DC electromotive force when it is drawn out from the brush end by the commutation of the commutator and the brush. The direction of the induced electromotive force is determined by the right-hand rule (the magnetic flux lines point to the palm of the hand, the thumb points to the direction of the conductor's movement, and the directions of the other four fingers are the directions of the induced electromotive force in the conductor). The direction of the force on the conductor is determined by the left-hand rule. This pair of electromagnetic forces forms a torque acting on the armature. This torque is called electromagnetic torque in a rotating motor. The direction of the torque is counterclockwise, attempting to make the armature rotate counterclockwise. If this electromagnetic torque can overcome the resistance torque on the armature (such as the resistance torque caused by friction and other load torques), the armature can rotate counterclockwise. A DC motor is an electric motor that runs on a DC working voltage and is widely used in radio recorders, video recorders, DVD players, electric shavers, hair dryers, electronic watches, toys, etc.

[0003] The application number is CN202222092754.7, and discloses a heat dissipation fan motor for a server, including a casing, a heat dissipation mechanism and a filtering mechanism. An organic unit is installed inside the casing, and a fan is fixedly connected to the left end of the unit. The utility model drives the fan blades to rotate to blow air to the left to dissipate heat in the server, thereby generating an airflow on the right side of the fan blades flowing to the left. At this time, the airflow can enter the casing from the air inlet pipe, and through the through grooves penetrating the limit sleeve card, the heat emitted from the unit in multiple groups of exhaust pipes evenly opened at the inner end of the through groove is driven to the left. When the filter needs to be removed, the push plate is pushed inward to move it in the push groove, and the card plate is squeezed inward to separate it from the card groove. The filter can be removed by pulling it upward. The ventilation and heat dissipation component is filtered by the dust filter component to avoid dust blocking, thereby improving the continuous stability of heat dissipation.

[0004] Although the above utility model drives the heat emitted from the unit in the multiple exhaust ducts evenly opened at the inner end of the through groove to the left by penetrating the limit sleeve card and the through groove, when the filter needs to be removed, the push plate is pushed inward to move it in the push groove, the card plate is squeezed inward to make it disengage from the card groove, and the filter can be removed by pulling upwards. The dust filter assembly filters the ventilation and heat dissipation assembly to avoid dust obstruction and improves the continuous stability of heat dissipation. However, there is a disadvantage that the connection effect of the device is not stable when it is in use, which may easily cause damage to internal parts due to looseness and falling.

[0005] Therefore, it is necessary to install a reinforced mounting plate assembly on the device so that when the device is used, its setting can provide a more stable and fixed installation method and a more secure connection to avoid falling off, greatly reducing the risk of falling due to looseness.
