[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. Specific Implementation Example 1
[0029] This embodiment is a high-power field-effect transistor with a heat dissipation chip.
[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a field-effect transistor body 2 is provided on the upper side of the support plate 1, and a connecting rod 3 is provided on the upper side of the support plate 1. The connecting rods 3 are arranged in an array. A heat sink chip body 5 is tightly attached to the upper side of the field-effect transistor body 2. The heat sink chip body 5 has mounting holes 4 inside. The mounting holes 4 are arranged in an array. The mounting holes 4 correspond one-to-one with the connecting rods 3. The connecting rods 3 are slidably connected to the mounting holes 4. The connecting rods 3 are threadedly connected to the connecting sleeves 6. The connecting sleeves 6 correspond one-to-one with the connecting rods 3. An ear plate 7 is provided on the outer side of the connecting sleeve 6. The ear plate 7 is symmetrical about the vertical central axis of the connecting sleeve 6.
[0031] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a heat sink 8 is provided on the upper side of the heat sink chip body 5. The heat sink 8 is arranged in an array. A slot 9 is provided inside the heat sink chip body 5. The slot 9 is symmetrical about the vertical central axis of the heat sink chip body 5. The slot 9 is slidably connected to the connecting block 10. The connecting block 10 is provided on the lower side of the cleaning plate 11. The slot 9 and the connecting block 10 correspond one-to-one. A cleaning plate 12 is provided on the lower side of the cleaning plate 11. The cleaning plate 12 is arranged in an array. The cleaning plate 12 is in close contact with both the heat sink chip body 5 and the heat sink 8.
[0032] It should be noted that after placing the MOSFET body 2 on the upper side of the support plate 1, and then placing the heat sink chip body 5 on the upper side of the MOSFET body 2, the MOSFET body 2 and the heat sink chip body 5 can be tightly fitted together. The upper side of the heat sink chip body 5 is provided with heat sinks 8, which can enhance the heat dissipation effect. Specific Implementation Example 2
[0034] This embodiment is designed to address the issue that the size and specifications of the field-effect transistor body 2 are limited by the snap-fit connection method, resulting in a narrow range of applications.
[0035] like Figure 1 , Figure 2 and Figure 3 As shown, after the heat dissipation chip body 5 is placed on the upper side of the support plate 1, the connecting sleeve 6 is threaded together with the connecting rod 3. At this time, the support plate 1 and the heat dissipation chip body 5 are connected together through the connecting sleeve 6. It can clamp and dissipate heat for support plates 1 of different sizes, and has a wide range of applications. In addition, the outer side of the connecting sleeve 6 is provided with an ear plate 7. The presence of the ear plate 7 makes it easy to rotate the connecting sleeve 6, which is more labor-saving. Specific Implementation Example 3
[0037] This embodiment is designed to address the problem that the heat dissipation chip body 5 and the heat sink 8 are prone to dust accumulation, which leads to poor heat dissipation performance.
[0038] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a slot 9 is provided on the upper side of the heat dissipation chip body 5. The slot 9 moves within the connecting block 10. Therefore, the slot 9 can prevent stubborn dust from remaining on the upper side of the heat dissipation chip body 5. When the cleaning plate 11 moves with the cleaning plate 11, the cleaning plate 11 and the cleaning plate 12 move upward, avoiding stubborn dust residue during cleaning. The connecting block 10 limits the cleaning plate 11. In addition, the heat dissipation fin 8 and the cleaning plate 12 are slidably connected and tightly fitted. Therefore, the moving cleaning plate 12 will clean the upper side of the heat dissipation chip body 5 and the heat dissipation fin 8, thereby enhancing the heat dissipation effect.
