Problems solved by technology

[0003] However, since the housing 91 is not designed for the specific electronic components on the circuit board B that are prone to heat, so as to quickly remove the heat generated by the electronic components, and no wind-dispelling design is made in the accommodating space 911 , Therefore, the heat generated by the circuit board B can only be slowly transmitted from the accommodating space 911 through the air hole 912 to the outside of the housing 91 through thermal diffusion.
However, because the above-mentioned heat dissipation method is extremely inefficient, the heat will still accumulate in the accommodating space 911 for a long time, and it is obviously impossible to effectively dissipate the heat to improve the operational reliability and use of the electronic components on the circuit board B. life

Abstract

The invention provides a motor assembly and a motor electrical box, used for solving the problem that an existing motor electrical box cannot effectively dissipate heat. The motor electric box comprises a heat conduction seat and a shell. The heat conduction seat is provided with a first side and a second side, the first side is used for being connected with a stator of a motor, and the shell is combined with the heat conduction seat. One side of the first side and the second side forms a cooling fin group, and the other side of the first side and the other side of the second side are used forbeing combined with a heating source of a circuit board of the motor in a heat conduction mode.

Description

technical field [0001] The present invention relates to a motor assembly and its motor electrical box, in particular to a motor electrical box that can effectively and quickly dissipate the operating heat generated by the circuit board of the motor to improve the operational reliability and service life of the motor. Background technique [0002] Please refer to figure 1 As shown, it is an existing ceiling fan motor electrical box 9 disclosed in the United States Publication No. US4637673 patent application, wherein the ceiling fan motor electrical box 9 has a shell 91, and the shell 91 is used to combine a fixed base S and A circuit board B. The housing 91 has an accommodating space 911 and a plurality of air holes 912, wherein the accommodating space 911 is used to accommodate the circuit board B, and each air hole 912 penetrates the wall of the housing 91 to communicate with the accommodating space 911 and the The outer space of the casing 91. Thereby, when the ceiling...
