Description

Technical Field

[0001] This utility model relates to the field of electric actuator technology, specifically an electric actuator with good heat dissipation. Background Technology

[0002] Actuators are an essential component of automatic control systems. Their function is to receive control signals from the controller, change the magnitude of the controlled medium, and thus maintain the controlled variable at the required value or within a certain range. Actuators can be classified into three main categories according to their energy source: pneumatic, hydraulic, and electric. Pneumatic actuators use compressed air as their energy source and are characterized by simple structure, reliable and stable operation, large output thrust, convenient maintenance, and fire and explosion protection.

[0003] However, existing electric actuators often generate a lot of heat during operation. If the internal heat dissipation is not good, it will be difficult to cool down the internal parts, which can easily cause overheating and overload inside the electric actuator, affecting its performance and lifespan. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: an electric actuator with good heat dissipation, comprising: a body, a connecting pipe fixedly connected to one bottom end of the body, a ventilation device fixedly connected to one bottom end of the connecting pipe, an air exchange port provided on one side end of the ventilation device, and a heat absorption column provided at one top end of the connecting pipe.

[0006] As a further embodiment of this utility model: a mounting base is provided at one end of the interior of the device, a motor is provided at one top end of the mounting base, and a controller is provided at the other end of the interior of the device.

[0007] As a further embodiment of this utility model: a shell is fixedly connected to one end of the top of the device body, a cooling fan is provided inside one end of the shell, and a heat dissipation vent is provided at the top of the shell.

[0008] As a further improvement of this utility model: a heat dissipation plate is provided at one end of the interior of the device, and a heat dissipation fin is provided at one end of the side of the device.

[0009] As a further improvement of this utility model, a power cord is electrically connected to one end of the bottom of the device.

[0010] As a further improvement of this utility model, the number of heat-absorbing columns is set in two sets, which are symmetrically arranged at both ends of the top of the connecting pipe.

[0011] As a further improvement of this utility model, the number of heat sinks and heat fins are both provided in four sets.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, the power cord is energized, and the internal motor and controller operate the device. The heat generated during operation is first absorbed by the heat-absorbing column and heat sink. The heat absorbed by the heat-absorbing column is released from the air vent through the ventilation device at its bottom. The heat absorbed by the heat sink inside the device is released through the heat sink fins connected to the heat sink on the outside of the device. The internal hot air is blown out by activating the cooling fan at the top of the device, which circulates the internal air and avoids the problem of poor internal heat dissipation, which can easily cause overheating and overload inside the electric actuator, affecting its performance and lifespan.
