Description

Technical Field:

[0001] The utility model relates to a heat dissipation structure of a three-phase flat linear asynchronous motor. Background Art:

[0002] At present, the three-phase flat linear asynchronous motor is mainly applied to the logistics system and is a power output component of the drive system. The existing radiators of the three-phase flat linear asynchronous motor are integral, with two fans. When the two fans cool the motor, the cooling air flows to both sides of the motor. One side flows to the end of the motor, and the other side flows to the middle part of the motor. At the middle position of the motor, the air forms a convection, which hinders the flow of the cold air and reduces the cooling and heat dissipation effect of the motor. The heat dissipation at the middle position of the motor is not good, and the heating of the motor affects the performance and service life of the motor. Summary of the Invention:

[0003] The purpose of the utility model is to provide a heat dissipation structure of a three-phase flat linear asynchronous motor with fast heat dissipation, better heat dissipation effect and increased service life of the motor. The technical solution of the utility model is: a heat dissipation structure of a three-phase flat linear asynchronous motor, in which the middle position of the upper part of the motor primary (1) is a middle radiator (5), and two end radiators (4) are installed on both sides of the middle radiator (5) at the upper part of the motor primary (1). A heat-conducting silica gel sheet (3) is pasted between the middle radiator (5), the end radiators (4) and the motor primary (1). The middle radiator (5) and the end radiators (4) are assembled with the yoke part of the motor primary (1) and fixed on the motor primary (1) by screws. The motor primary (1) is fixed on the U-shaped bracket (2) by bolts. Three cooling fans (6) are fixed on the ventilation openings (7) of the U-shaped bracket (2) with screws, and the cooling fans (6) are on the U-shaped side of the U-shaped bracket (2).

[0004] The U-shaped bracket (2) has ventilation openings (7). The cooling fans (6), the U-shaped bracket (2) and the radiators form a wind cavity, and the dimensions of the heat dissipation teeth at the contact part of the heat dissipation teeth of the end radiators (4) and the middle radiator (5) are shortened.

[0005] Technical Effects of the Utility Model:

[0006] Thermal conductive silicone pads are respectively pasted on the non-heat-dissipating tooth side planes of the two-end radiators and the middle radiator. The thermal conductive silicone pads on the radiators are tightly connected to the yoke part of the motor primary iron core and are installed together on one side of the U-shaped bracket. The cooling fan is installed on the U-shaped side of the U-shaped bracket, and the U-shaped bracket is provided with ventilation openings; the radiators and the U-shaped bracket form an air duct for the motor. The two-end radiators cool the motor along the length direction of the motor, and the middle radiator cools the middle part of the motor perpendicular to the length direction of the motor. The cooling fan installed at the ventilation opening of the U-shaped bracket blows the cooling air into the heat-dissipating tooth grooves of the radiator. A thermal conductive silicone pad is pasted at the connection between the radiator and the motor primary, which can quickly conduct the heat generated by the motor primary to the radiator; the cooling air of the fan cools the motor primary through the radiator. The heat-dissipating teeth at the contact between the heat-dissipating teeth of the two-end radiators and the middle radiator are shorter, so that the cooling air can flow out smoothly, and the cooling air circulates continuously to remove the heat generated by the motor primary; the tooth groove direction of the middle radiator is perpendicular to the direction of the two-end radiators, and the cooling air of the cooling fan only cools the middle part of the motor primary. The motor primary has fast heat dissipation and good effect.

[0007] In the utility model, the two-end radiators are responsible for cooling both sides of the motor, and the middle radiator is responsible for cooling the middle part of the motor, without interfering with each other. The heat-dissipating teeth at the contact between the two-end radiators and the middle radiator are shorter, so that when the cooling air cools the motor, it can flow out from the short teeth, achieving better cooling effect for the motor; thermal conductive silicone pads are pasted on the non-heat-dissipating tooth groove sides of the three radiators and are tightly connected to the yoke part of the motor iron core, increasing the heat conduction effect between the motor iron core and the radiator.
