[0003] Currently, under high-power operating conditions, MOSFETs generate a large amount of heat. If heat cannot be dissipated in a timely and effective manner, the temperature of the MOSFET will rise, which will affect its performance and reliability, shorten its service life, and may even cause it to be damaged due to overheating. Existing surface-mount MOSFETs have poor heat dissipation performance. In addition, when dust or impurities accumulate on the heat dissipation structure and affect the heat dissipation effect, the existing heat dissipation structure is usually difficult to install and disassemble, making it inconvenient to clean and difficult to maintain long-term heat dissipation.

[0023] 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.

[0024] Example:

[0025] Please see Figure 1 - Figure 4 This embodiment discloses a novel surface-mount MOSFET, comprising a MOSFET body 1, on which a heat dissipation mechanism is provided to improve the heat dissipation function of the MOSFET body 1 and facilitate its long-term use. A fixing mechanism is also provided on the MOSFET body 1 to facilitate the installation and removal of the heat dissipation mechanism and cleaning, thereby maintaining a sustained heat dissipation effect. The heat dissipation mechanism includes limiting blocks 31, which are fixedly installed on the MOSFET body 1 and are used to receive the insertion of a heat absorption plate 34. A heat absorption plate 34 is inserted between the limiting blocks 31. A first heat dissipation fin 33 is fixedly installed on the heat absorption plate 34, and second heat dissipation fins 32 are fixedly installed at both ends of the heat absorption plate 34. A heat dissipation through hole 35 is provided on the heat absorption plate 34. The presence of the first heat dissipation fin 33, the second heat dissipation fin 32, and the heat dissipation through hole 35 enhances the heat dissipation effect of the MOSFET body 1.

[0026] The fixing mechanism includes a bracket 21, which is fixedly installed on the MOS tube body 1. A housing 22 is fixedly installed on the bracket 21. A slider 23 is slidably arranged on the inner wall of the housing 22. A plug rod 27 is fixedly installed on one side of the slider 23. One end of the plug rod 27 passes through the inner wall of the bracket 21. A slot 28 is opened on the heat absorption plate 34. A pull rod 25 is fixedly installed on the other end of the slider 23. One end of the pull rod 25 passes through the housing 22. A handle 24 is fixedly installed on one end of the pull rod 25. The handle 24 is provided for pulling the pull rod 25 to move.

[0027] There are four limiting blocks 31, and all four limiting blocks 31 are square blocks. The limiting blocks 31 are used to support the insertion of the heat absorption plate 34.

[0028] The heat absorber plate 34 is arched in shape and is attached to the surface of the MOS tube body 1. The heat absorber plate 34 is designed to absorb heat.

[0029] The first heat dissipation fin 33 is in the shape of a strip plate, the second heat dissipation fin 32 is in the shape of a strip plate, and the heat dissipation through hole 35 is in the shape of a cylindrical hole. By setting the first heat dissipation fin 33, the second heat dissipation fin 32 and the heat dissipation through hole 35, the heat dissipation effect of the MOSFET body 1 is improved.

[0030] There are two brackets 21, which are symmetrically arranged with the MOS transistor body 1 as the center. The brackets 21 are L-shaped and are used to support the installation of the housing 22.

[0031] The box 22 is cylindrical in shape and is horizontally positioned. The insert rod 27 is cylindrical in shape, the slot 28 is cylindrical in shape, the handle 24 is circular in shape, and the pull rod 25 is cylindrical in shape and is horizontally positioned. The pull rod 25 is used to pull the slider 23 to slide along the inner wall of the box 22.

[0032] A spring 26 is fixedly installed on the inner wall of the housing 22. The spring 26 is wound around the pull rod 25. One end of the spring 26 is fixedly connected to the slider 23. The spring 26 is used to apply force to the insertion rod 27 so that the insertion rod 27 can be inserted into the slot 28.

[0033] When the MOSFET body 1 is working, the heat absorption plate 34 will absorb the heat generated by the MOSFET body 1. The heat absorption plate 34 is provided with a first heat dissipation fin 33, a second heat dissipation fin 32 and a heat dissipation through hole 35 to increase the contact area between the air and the heat absorption plate 34, thereby improving the heat dissipation efficiency and facilitating the long-term operation of the MOSFET body 1.

[0034] When the first heat sink fin 33 and the second heat sink fin 32 have been used for a long time and dust has accumulated on their surfaces, they need to be cleaned. Pull the handles 24 on both sides. The handles 24 drive the slider 23 to slide in a straight line along the inner wall of the housing 22 via the pull rod 25. When the slider 23 slides in a straight line, it will drive the insertion rod 27 to move until one end of the insertion rod 27 leaves the slot 28. At this time, the heat absorption plate 34 can be removed from the surface of the MOS tube body 1, so as to facilitate the cleaning of the surface of the heat absorption plate 34 and avoid dust accumulation, which will affect heat dissipation.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
