Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings.

Example 1

The novel air conditioner compressor stator shown in the figures 1-3 comprises a stator body 1, wherein an assembly groove 2 is formed in the inner wall of the stator body 1, a heat dissipation ring 3 is arranged on the assembly groove 2, a temperature sensor 4 is arranged on the heat dissipation ring 3, a PCB 5 is arranged on the outer wall of the stator body 1, the PCB 5 is electrically connected with the temperature sensor 4, and the PCB 5 is further connected with a motor power switch in series.

The PCB 5 is connected to the outer wall of the stator body 1 by a connecting element 6, the connecting element 6 has two

spring legs

61, 62, the two

spring legs

61, 62 are connected to each other by a combined element 63, a through hole 64 is provided on the combined element, the free end of each spring leg has a

catch element

65, 66 for fixing to the stator, and the

catch elements

65, 66 of the

spring legs

61, 62 are configured as hook-shaped. The PCB circuit board 5 is provided with a through hole 64, and the through hole 64 is plated with an anti-oxygen material.

The electroplating anti-oxygen material is made of aluminum, a bolt nut is arranged between the through hole 64 on the combined element 63 and the through hole on the PCB 5, and the PCB and the connecting element are connected through the bolt nut.

The heat dissipation ring 3 with be equipped with ventilation hole 7 between the outer wall of stator body 1, ventilation hole 7 quantity is 6, 6 ventilation hole 7's position is equidistance evenly distributed.

The stator structure is characterized in that a motor shaft 8 is arranged in the stator body 1, a fan 9 is arranged on the motor shaft, and the fan 9 is electrically connected with the PCB 5.

The working principle of the embodiment is as follows: on heat transfer that the stator sent the cooling ring, when measuring the temperature and being higher than 60 degrees, the fan began work, when windy comes out from ventilation hole and fan, takes away the heat on the cooling ring through wind, consequently, is favorable to making the heat in time to obtain giving off, when measuring the temperature and being higher than 105 degrees, temperature sensor passed the signal for the PCB circuit board, and the PLC circuit board makes the disconnection of motor power, and the motor stop work, stator temperature decline gradually.

Connecting element makes PCB circuit board and stator be connected more firmly, thereby be difficult to drop and lead to the trouble, the ventilation hole has improved the radiating effect, reduce the stator temperature, improve compressor life, the fan is showing improvement to the radiating efficiency, only when exceeding the uniform temperature, the fan just begins work, be favorable to the energy saving, the protection effect has been played to the environment, the rectangle through-hole has plated the electroplating oxygen-proof material and can prevent the oxidation, avoid the time overlength through-hole to rust, lead to the problem.

Compared with the prior art, the invention improves the heat dissipation capacity of the stator, prolongs the service life of the motor, and can stop the motor in time when the temperature of the stator is overhigh so as to prevent accidents and cause personnel and economic losses.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. The present invention is not limited to the above-described embodiments, which are described in the specification and illustrated only for illustrating the principle of the present invention, but various changes and modifications may be made within the scope of the present invention as claimed without departing from the spirit and scope of the present invention.
