Referring to fig. 1-2, the transistor mounting structure in the embodiment of the present invention includes an installation portion 1 and a fixing portion 2, where the installation portion 1 is used to install the transistor mounting structure on a heat sink 4, and the fixing portion 2 is used to contact a transistor 3 and press the transistor 3 to the heat sink 4. The mounting portion 1 is provided with a mounting protrusion 11, and the fixing portion 2 is provided with a fixing protrusion 21, wherein the mounting protrusion 11 is used for abutting against the heat sink 4, and the fixing protrusion 21 is used for abutting against the transistor 3. A mounting hole 12 is provided between the mounting protrusion 11 and the fixing protrusion 21. Referring to fig. 3, screws may be passed through the mounting holes 12 and connect the present transistor mounting structure and the heat sink 4 together. When the screw is tightened, the transistor mounting structure takes the mounting convex strip 11 as a fulcrum, the transistor 3 is pressed towards the radiator 4 through the fixing convex strip 21, and the change of the tightening force can influence the pressure on the transistor 3, so that the transistor mounting structure has a certain pressure adjusting function; moreover, the fixed convex strips 21 are in line-surface contact with the transistor 3, so that a larger contact area is provided compared with the traditional point-surface contact, and the problem of uneven heat dissipation caused by the warping of the edge of the transistor 3 can be solved.

Furthermore, the transistor mounting structure is an integrated structure, and the mounting part 1 and the fixing part 2 are part of the transistor mounting structure, so that the structure is simplified.

Further, the mounting protrusion 11 is parallel to the fixing protrusion 21, preventing unstable connection due to a deflection force when tightening the screw.

Furthermore, the two ends of the mounting convex strip 11 are respectively extended with a side wing convex strip 13, so that the contact area between the mounting part 1 and the radiator 4 is further increased, and the connection is more stable.

Further, one end of the side wing convex strip 13 is an inclined plane structure, and when the transistor mounting structure is slightly turned over during connection, the mounting part 1 can still be kept in close contact with the heat sink 4 through the inclined plane structure.

Further, the surface of the fixing protrusion 21 is a curved surface, so that when the present warning pipe mounting structure is slightly turned over during connection, the fixing portion 2 can still be held in line-surface contact with the transistor 3 by the curved surface connection surface.

Further, the fixing portion 2 is further provided with a fixing peg 22, and the fixing peg 22 protrudes from the surface of the fixing portion 2 and is adapted to the reserved hole of the transistor 3 to prevent the transistor 3 from loosening or shifting.

Further, spud 22 includes two portions, first spud 221 and second spud 222, respectively, with a space therebetween. When the preformed hole of the transistor 3 is smaller than the fixing piles 22, the first fixing pile 221 and the second fixing pile 222 are extruded and close to each other, so that the positioning effect of the transistor 3 with the smaller preformed hole can be realized, and the applicability of the transistor mounting structure is improved.

Furthermore, the fixing portion 2 is further provided with two side baffles 23, the two side baffles 23 are respectively arranged on two sides of the fixing portion 2, and the side baffles 23 and one side surface of the mounting portion 1 together enclose an accommodating space 24, and the transistor 3 is accommodated in the accommodating space 24. The transistor 3 can be protected by providing an accommodating space 24 outside the transistor 3.
