Description

Technical Field

[0001] This utility model relates to the field of electric actuator technology, specifically to a heat dissipation device for electric actuators. Background Technology

[0002] Electric actuators are key components in industrial automation systems and are widely used in the drive control of various valves, dampers and other equipment.

[0003] During high-load or long-term operation, the internal motor, gearbox, and electronic control module of an electric actuator generate a large amount of heat. Traditional electric actuators mostly use natural convection cooling, relying on heat exchange between the outer casing and the air. This has low heat dissipation efficiency, especially in high-temperature environments or confined spaces, which can easily cause overheating and damage to internal components, reducing operational reliability. Although some electric actuators are equipped with fans or heat sinks, these components are usually integrated inside the casing. Once a failure occurs, repair or replacement is extremely inconvenient, and may even require the replacement of the entire device. Therefore, there is a need for a heat dissipation device for electric actuators that is easy to maintain. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the heat dissipation efficiency is low and the internal heat dissipation mechanism is not easy to maintain. This utility model provides a heat dissipation device for electric actuators that is easy to maintain.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a heat dissipation device for an electric actuator, comprising an electric actuator body and a heat dissipation mechanism;

[0006] The heat dissipation mechanism includes a mounting base plate and heat dissipation frames; the electric actuator body can be detachably installed in the center of the top surface of the mounting base plate, and a pair of heat dissipation frames are mirrored on the mounting base plate. After the two heat dissipation frames are brought closer to each other under the action of the adjustment mechanism, they are close to the outer walls on both sides of the electric actuator body.

[0007] Two heat dissipation frames are located on both sides of the electric actuator body, and air-cooling mechanisms facing the electric actuator body are respectively installed on the wall.

[0008] As an improvement, positioning rings are provided at each corner of the electric actuator body. After the electric actuator body is placed in the center of the top surface of the mounting base plate, positioning threaded rods that pass through each positioning ring are welded to the top surface of the mounting base plate. After the nuts are threadedly connected to each positioning threaded rod, they are tightly attached to the top surface of the positioning rings.

[0009] As an improvement, the adjustment mechanism includes an adjustment screw and an adjustment groove;

[0010] The top surface of the mounting base plate has a pair of adjustment slots. The two heat dissipation frames are respectively slidably installed in the two adjustment slots by sliders. There is a pair of adjustment screws. After the two adjustment screws rotate in the two adjustment slots, they are threadedly connected with the sliders sliding in the adjustment slots. One end of the screws extends to the outside and is connected to a handle.

[0011] As an improvement, the air-cooling mechanism includes a cooling fan; the cooling fan is embedded in a pre-set through hole on the two heat sink frames.

[0012] As an improvement, the air-cooling mechanism also includes a dust filter, and the dust filter with matching through holes can be detachably connected to both the inner and outer walls of the heat sink frame.

[0013] As an improvement, both the inner and outer walls of the two heat dissipation frames are provided with mounting frames that have matching through holes. Each mounting frame has a pair of mounting slots mirrored on the side away from the heat dissipation fan. A pair of T-shaped rods that are adapted to the mounting slots are provided on the dust screen. The mounting slots are T-shaped slots.

[0014] As an improvement, a radiator is also included, which is embedded in the top wall of the two heat dissipation frames and moves to the top of the electric actuator body under the action of the adjustment mechanism.

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] 1. The two heat sink frames are equipped with built-in cooling fans to form directional airflow and actively cool both sides of the electric actuator. The distance of the heat sink frames is adjustable to ensure close contact with the actuator shell and improve heat exchange efficiency.

[0017] 2. The air-cooled mechanism is equipped with a detachable dust filter to prevent dust from entering the actuator. The dust filter adopts a T-shaped rod plug-in structure, which is convenient for quick installation, removal and cleaning.

[0018] 3. An embedded heat sink is provided at the top to assist in heat dissipation of the upper part of the actuator, achieving three-dimensional cooling;

[0019] 4. The electric actuator is fixed to the center of the mounting base plate by a positioning ring, threaded rod, and nut, which ensures precise positioning and convenient disassembly. Attached Figure Description

Positioning rings 4 are provided at each corner of the electric actuator body 1. After the electric actuator body 1 is placed in the center of the top surface of the mounting base plate 2, a positioning threaded rod 5 passing through each positioning ring 4 is welded to the top surface of the mounting base plate 2. After the nut 6 is threadedly connected to each positioning threaded rod 5 until it is tightly attached to the top surface of the positioning ring 4, the electric actuator is fixed in the center of the mounting base plate 2 by the positioning ring 4 + threaded rod + nut 6, which provides accurate positioning and convenient disassembly.

[0030] After the two heat dissipation frames 3 move closer to each other under the action of the adjustment mechanism, they are close to the outer walls on both sides of the electric actuator body 1. The adjustment mechanism includes an adjustment screw 7 and an adjustment groove 8. A pair of adjustment grooves 8 are opened on the top surface of the mounting base plate 2. The two heat dissipation frames 3 are respectively slidably set in the two adjustment grooves 8 by sliders. A pair of adjustment screws 7 are provided. After the two adjustment screws 7 rotate in the two adjustment grooves 8, they are threadedly connected with the sliders sliding in the adjustment grooves 8. One end extends to the outside and is connected to a handle 9 to ensure that it fits the actuator shell, improves the heat exchange efficiency, and facilitates the maintenance of the actuator and the device.

[0031] Two heat dissipation frames 3 are located on both sides of the electric actuator body 1. The walls are respectively provided with air cooling mechanisms facing the electric actuator body 1. The air cooling mechanism includes a heat dissipation fan 10. The heat dissipation fan 10 is embedded in the pre-set through holes on the two heat dissipation frames 3.

The top embedded radiator 15 provides auxiliary heat dissipation for the upper part of the actuator, realizing three-dimensional cooling.

[0035] In the specific implementation of this utility model, the electric actuator is placed in the center of the mounting base plate 2, and the positioning rings 4 at each corner are fitted into the positioning threaded rods 5 on the base plate. The nuts 6 are tightened from above to make the electric actuator firmly fixed on the base plate. The adjusting handle 9 is rotated to drive the adjusting screw 7 to rotate, so that the heat dissipation frame 3 slides along the adjusting groove 8. After the two heat dissipation frames 3 come close to each other, they are pressed against the outer walls of both sides of the electric actuator to form an effective heat dissipation channel.

[0036] Start the cooling fan 10, and the fan blows cold air to both sides of the electric actuator to accelerate heat dissipation. The installed dust filter 11 prevents dust from entering while ensuring good airflow circulation. The top embedded radiator 15 is turned on to provide concentrated heat dissipation to the top area.
