Furthermore, the number of the second positioning columns is two, the two second positioning columns are respectively located on two sides of the working portion, and the two second positioning columns are located at the same horizontal height.
The two second positioning columns are respectively positioned at the same height of two sides of the working part, so that the weight of the radiating fins can be reduced as much as possible while the balance of the stress received by the left side and the right side of the working part in work is ensured, and the lightness and miniaturization of the electric appliance are ensured.
Furthermore, the height of the second positioning column is smaller than that of the working part.
Preferably, the connecting part is of a flat plate-shaped structure.
The flat plate-shaped structure can enable the electronic component to have larger contact area with the radiating fin under the condition of the same mass and volume, so that the radiating effect of the electronic component is better.
Another object is to provide a method for riveting an electronic component and a heat sink, comprising the following steps:
s1, folding the fixed claws upwards to form an included angle of 90 degrees with the radiating fins;
and S2, sleeving the positioning hole on the electronic component on the first positioning column, and enabling the connecting part to abut against the fixing claws on the two sides of the connecting part, so that the working part abuts against the second positioning columns on the two sides of the connecting part.
And S3, bending the bending part at the top of the positioning claw towards the connecting plate, so that the bending part is positioned above the connecting plate and is abutted against the connecting plate.
The principle and effect of the present invention will be further explained by combining the above technical solutions:
the fixing claws are arranged on the radiating fins, and the electronic components are fixed on the radiating fins by the fixing claws, so that the fixing structure is firm, an additional fixing device is omitted, the weight of the fixing structure of the electronic components and the radiating fins is reduced, the material is saved, and the processing technology is simplified.
