Clamped aluminum alloy heat sink with elastic clip

Abstract

The invention discloses a clamped aluminum alloy heat sink with an elastic clip. The clamped aluminum alloy heat sink is characterized by comprising an aluminum alloy main body and the elastic clip, wherein the aluminum alloy main body is provided with a back plate, a horizontal plate, wing plates and a clamping plate, the horizontal plate is connected onto the back plate, the horizontal plate and the back plate are perpendicular to each other and are integratedly inverted L-shaped, the wing plates are connected above the horizontal plate and distributed at equal distance from one side of the back plate to one side far away from the back plate, the clamping plate is arranged below the horizontal plate, the upper end of the clamping plate is connected with one side, far away from the back plate, of the horizontal plate via a corrugated elastic sheet, the lower segment of the clamping plate is an arc plate, the arc axial line of the arc plate is parallel to the lower surface of the horizontal plate and the inner surface, connected with the lower surface of the horizontal plate, of the back plate respectively, a back surface, opposite to an arc center, on the arc plate is an arc press surface, the arc press surface is near to the back plate, a limitation groove is arranged on each of one side of the arc center of the arc plate and the back surface of the back plate and is parallel to an arc axis of the arc plate, the elastic clip is an U-shaped clip, and two clamping ends of the U-shaped clip are respectively engaged in the two limitation grooves. The clamped aluminum alloy heat sink is relatively simple in fabrication and installation processes and is suitably used for promotion and application.

Description

technical field [0001] The invention relates to a cooling fin made by cutting an aluminum alloy extruded profile, in particular to an elastic clamp clamping type aluminum alloy cooling fin. Background technique [0002] my country is a big industrial country.

AI Technical Summary

Problems solved by technology

Existing aluminum profiles used as heat sinks for power tubes in electronic products are all composed of a base plate and a wing plate. Screws fix the power tube on the base plate of the radiator first and then weld it to the circuit board. The tightening strength of the screws is not very good. It depends on the feeling of the workers. Too loose will affect the heat transfer, and too tight will easily cause stress on the package and affect the power. The performance of the tube, the poor stress release caused by thermal expansion and contraction will also affect the performance of the power tube, and the power tube will be displaced when the screw is twisted, making it deviate from the predetermined position, affecting the later installation or irregular after installation, Soldering to the circuit board and then installing the heat sink with screws will easily damage the solder joints. At present, the above problems can only be solved by the proficiency of the workers, and each heat sink must be processed with threaded holes or drilled holes. The process is more troublesome, and these still need to be solved by technology
