Description

A motor cooling case

technical field

The utility model relates to the electromechanical field, in particular to a heat dissipation housing for a motor.

Background technique

The motor usually includes an external shell, an internal rotor, a stator and other components. The shell wraps the internal components. When working, the internal rotor rotates at a high speed, which will generate a lot of heat under long-term use. A large amount of heat cannot be dissipated, so that the internal components work in a high-temperature environment for a long time, which is easy to cause damage to the components, and cannot guarantee the stability and reliability of their work.

Contents of the invention

The purpose of the present utility model is to provide a heat dissipation housing for a motor to solve the problems raised in the above-mentioned background technology.

In order to achieve the above object, the utility model provides the following technical solutions:

A heat dissipation housing for a motor, comprising a rotor, a sealed housing, a ventilation hole, a fan cover and a cooling fan, the rotor is fixed inside the sealed housing through a limit plate, the end of the rotor is connected to the motor shaft, and the side of the sealed housing is opened There are a number of ventilation holes, the upper part of the ventilation holes is uniformly provided with a dust shield, the other end of the sealed housing is installed with a fan cover through bolts, a cooling fan is installed in the fan cover, and a plurality of fan blades are arranged on the cooling fan. An air outlet is arranged on the top, and a plurality of cooling fins are arranged outside the air outlet, and the cooling fan is connected to the rotor through a transmission shaft.

As a further solution of the utility model: the sealed casing is a cast metal casing.

As a further solution of the utility model: the motor rotating shaft is connected to the outside through a bearing provided on the sealed housing.

As a further solution of the present utility model: the dust shield and the sealing shell are integrally cast.

Compared with the prior art, the beneficial effect of the utility model is: the motor heat dissipation housing has a simple structure, low production cost, and is easy to process, increases the active heat dissipation of the heat dissipation fan, increases the air flow rate inside and outside the sealed housing, and does not It is necessary to increase the volume of the sealed shell to dissipate the heat in time. It is very convenient to use, has good stability and high heat dissipation efficiency.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1, in the embodiment of the present utility model, a kind of motor heat dissipation shell, comprises rotor 1, sealing shell 4, ventilation hole 7, fan cover 10 and cooling fan 13, and described sealing shell 4 is that thermal conductivity is relatively A good cast metal shell, the inside of the sealed shell 4 is fixed with the rotor 1 through the limit plate 6, the end of the rotor 1 is connected to the motor shaft 3, and the motor shaft 3 passes through the bearing 2 arranged on the sealed shell 4 to connect with the outside , the side of the sealed housing 4 is provided with a number of ventilation holes 7, the upper part of the ventilation holes 7 is evenly provided with a dust shield 5, the dust shield 5 and the sealed housing 4 are integrally cast, and the other end of the sealed housing 4 passes through The bolt 9 is equipped with a fan cover 10, and a cooling fan 13 is installed in the fan cover 10. A plurality of fan blades 14 are arranged on the cooling fan 13. The fan cover 10 is provided with an air outlet 11, and the outside of the air outlet 11 is provided with A plurality of cooling fins 12 , the cooling fan 13 is connected to the rotor 1 through the transmission shaft 8 .

When the rotor 1 rotates, the rotor 1 itself will emit a large amount of heat. The rotor 1 drives the cooling fan 13 to rotate through the transmission shaft 8, and the outside air enters through a number of ventilation holes 7 provided on the side of the sealed casing 4. The cooling fan 13 will The heat of the sealed casing 4 is exhausted through the air outlet 11, and the heat is dissipated through a plurality of cooling fins 12, so that the temperature in the sealed casing 4 drops to the temperature required for the normal operation of the rotor 1, and the rotor 1 is prevented from burning out.

The working principle of the utility model is: the motor heat dissipation housing has a simple structure, low production cost, and is easy to process, and the heat dissipation fan 13 is added to actively dissipate heat, and the air flow rate inside and outside the sealed housing 4 is increased, and the sealing shell does not need to be increased. The volume of the body 4 can dissipate the heat in time, which is very convenient to use, has good stability and high heat dissipation efficiency.
