Description

Technical Field

[0001] This utility model relates to the field of driver technology, specifically to an integrated heat dissipation and protection device for a driver. Background Technology

[0002] A driver is an electronic device mainly used to control the operation of actuators such as motors. It receives command signals from the controller, such as speed, direction, and torque, and then converts these signals into electrical signals suitable for the operation of the motor, thereby driving the motor to operate in a set manner. Drivers play a vital role in modern automated control systems and are widely used in many fields such as industrial production, robotics, automotive electronics, and home appliances.

[0003] There are many types of drivers. Depending on the type of motor being controlled, there are DC motor drivers, AC motor drivers, stepper motor drivers, servo motor drivers, etc. Different drivers have different performance characteristics and application scenarios, but their core function is to convert control signals into motor drive signals to achieve effective control of the motor. With the continuous advancement of technology, the performance of drivers is also constantly improving, developing towards higher precision, higher efficiency, and smaller size, providing strong support for the intelligence and automation of various devices.

[0004] To ensure the heat dissipation and protection capabilities of the drive, an integrated heat dissipation and protection device is required. This device typically uses a closed enclosure to protect the drive and a cooling fan to dissipate heat. While this method provides some protection and heat dissipation, relying solely on a cooling fan is insufficient to provide excellent cooling. Due to the enclosure, the heat generated during drive operation accumulates inside and is difficult to dissipate in time. Furthermore, relying solely on a cooling fan can lead to poor heat dissipation in certain areas due to limitations in installation location and airflow range. This can result in localized overheating and damage to the drive. Therefore, this paper proposes an integrated heat dissipation and protection device for the drive to address these issues.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] Please see Figures 1-10 This utility model provides a technical solution:

[0030] An integrated heat dissipation and protection device for a driver includes a protective housing 1. A door 2 is hinged to the front of the protective housing 1. A driver body 3 is installed inside the protective housing 1. A first heat dissipation component 4 is provided between the driver body 3 and the side wall of the protective housing 1. A second heat dissipation component 5 is provided on the top and rear walls of the protective housing 1. The second heat dissipation component 5 includes a heat dissipation mesh plate 51 provided on the rear wall of the protective housing 1 and a heat dissipation fan 52 provided on the top of the protective housing 1. The heat dissipation fan 52 passes through the top wall of the protective housing 1 and is fixedly connected to the top wall of the protective housing 1. A dustproof mesh plate 53 is provided above the heat dissipation fan 52. The dustproof mesh plate 53 matches the top specifications of the heat dissipation fan 52. A connecting component 54 is provided between the dustproof mesh plate 53 and the heat dissipation fan 52.

[0031] As a further implementation of this solution, the first heat dissipation component 4 includes several heat pipes 41. The outer wall of the protective box 1 is fixedly connected with a radiating heat dissipation fin 42. The heat dissipation fin 42 has several connection holes 43 that are equal in number, corresponding in position, and matching in specifications to the heat pipes 41. One end of the heat pipe 41 passes through the side wall of the driver body 3 and contacts the internal heat-generating part of the driver body 3. The other end of the heat pipe 41 passes through the side wall of the protective box 1 and the connection hole 43 and contacts the heat dissipation fin 42 through the connection hole 43. The first heat dissipation component 4 can conduct heat to the heat-generating part of the driver body 3 in a targeted and rapid manner, so that the heat generated by the driver body 3 during operation can be quickly dissipated, preventing the heat inside the driver body 3 from accumulating and affecting the internal components of the driver body 3.

[0032] As a further implementation of this solution, the connecting component 54 includes connecting clips 541 fixedly connected to the four corners of the bottom of the dustproof mesh plate 53. The connecting clips 541 are arrow-shaped with a wider top and narrower bottom and forked sides. A return spring 542 is fixedly connected to the forked part of the connecting clips 541. Connecting slots 543 are provided at the four corners of the top of the cooling fan 52. The connecting slots 543 and the connecting clips 541 are positioned correspondingly and matched in specifications. This configuration can provide a good connection between the dustproof mesh plate 53 and the cooling fan 52. Therefore, it can not only ensure the connection strength between the dustproof mesh plate 53 and the cooling fan 52 during normal use, but also facilitate the disassembly of the dustproof mesh plate 53 when cleaning and maintenance are required.

[0033] As a further implementation of this solution, the connecting component 54 also includes a first magnetic groove 544 located at the four corners of the top of the cooling fan 52 and a second magnetic groove 546 located at the bottom of the dustproof mesh plate 53 and on both sides of the connecting clip 541. A first magnetic block 545 is embedded in the first magnetic groove 544, and a second magnetic block 547 is embedded in the second magnetic groove 546. The top of the first magnetic block 545 is flush with the top of the cooling fan 52, and the second magnetic block 547 is flush with the bottom of the dustproof mesh plate 53. The first magnetic block 545 and the second magnetic block 547 are set with opposite magnetic poles that match the specifications and are positioned accordingly. This arrangement can improve the connection strength between the dustproof mesh plate 53 and the cooling fan 52.

[0034] Workflow: First, power on all electrical appliances and connect an external controller. Install the driver unit 3 inside the protective box 1. The protective box 1 and the box door 2 provide good sealing protection for the driver unit 3, greatly reducing the possibility of the driver unit 3 being affected by external impacts and dust and moisture. The first heat dissipation component 4 can conduct targeted and rapid heat to the heat-generating parts of the driver unit 3. The heat pipe 41 is made of copper and filled with working fluid. The heat generated during the operation of the driver is absorbed by the contact end of the heat pipe 41. After absorbing heat, the working fluid inside the heat pipe 41 will quickly vaporize. The vaporized water vapor diffuses along the inner wall of the heat pipe 41 to the other end. Since the other end of the heat pipe 41 is in contact with the heat dissipation fins 42 through the connection hole 43, when water... When the steam reaches the other end of the heat pipe 41, it encounters the low-temperature environment of the heat dissipation fins 42 area, rapidly condenses and releases heat. The condensed water returns to the end of the heat pipe 41 near the driver body 3 through capillary action. This cycle repeats, transferring heat from inside the driver body 3 to the heat dissipation fins 42 area outside the protective casing 1. The heat dissipation fins 42 are arranged in a divergent pattern, which increases the contact area with the outside air. The air exchanges heat with the heat dissipation fins 42, carrying away the heat and allowing the heat generated during the operation of the driver body 3 to dissipate quickly, preventing heat accumulation inside the driver body 3 from affecting its internal components. The second heat dissipation component 5 can dissipate heat inside the protective casing 1, and the cooling fan 52 can dissipate external heat. Air is blown into the protective enclosure 1, providing good air circulation inside. Heat inside the enclosure 1 is dissipated through the heat dissipation mesh 51 via air heat exchange. The dust filter 53 filters impurities from the air drawn in by the cooling fan 52, preventing external impurities from entering the enclosure 1 and affecting the driver body 3. The connecting component 54 provides a good connection between the dust filter 53 and the cooling fan 52, ensuring the connection strength between them during normal use and facilitating disassembly of the dust filter 53 when cleaning or maintenance is required. When connecting the dust filter 53 and the cooling fan 52, first connect the dust filter 53... Placed on top of the cooling fan 52, the connecting clips 541 at the four corners of the bottom of the dust filter plate 53 are inserted into the corresponding connecting slots 543 on the top of the cooling fan 52. The forked expansion ends on both sides of the connecting clips 541 will deform inward due to the pressure of the inner wall of the connecting slots 543, and at the same time, they will press the return spring 542. The return spring 542 will then drive the forked expansion ends on both sides of the connecting clips 541 to expand outward and return to their original position through its own elastic force, so that the connecting clips 541 are locked in the connecting slots 543. At the same time, the second magnetic block 547 in the second magnetic groove 546 will contact and magnetically attract the first magnetic block 545 in the first magnetic groove 544 to improve the connection strength between the dust filter plate 53 and the cooling fan 52. The same principle applies when disassembling, cleaning and maintaining.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
