Embodiment Construction
[0056] The present invention will be described in detail below in conjunction with accompanying drawing and specific embodiment:
[0057] figure 1 Shown is the first preferred embodiment of the present invention, and the manufacturing steps are mainly followed in sequence: pumping, cutting, grooving, implanting and stamping to complete the heat dissipation base 1 and heat dissipation fins 2. Quick combine, where:
[0058] Extrusion: It is formed by selecting aluminum or copper metal for extrusion, and then extruded into a long extruded body 10 (such as figure 2 ), and on the upper end surface of the long extruded body 10, more than one set of extending clamping strips 101, 102 that can be symmetrical in pairs (or can also be implemented as having only a single extending clamping strip 101 or 102), and the long extruded The body 10 can be extruded into a thin plate shape;
[0059] Cutting: According to the required length of the heat dissipation base, the long extruded body...

The invention provides a radiator and a manufacturing method thereof. The method includes: forming an elongated extruded part by means of drawing-extruding molding through procedures such as drawing-extruding, cutting, grooving, inserting, stamping and the like, forming more than a group of extending clamping strips on the upper end face of the elongated extruded part, cutting the elongated extruded part into individual extruded parts, grooving the extending clamping strips at intervals to form a plurality of groups of clamping blocks at intervals, forming a notched flanged plate at the bottom end of each radiating fin to enable the radiating fins to be inserted to a radiating base, and using a die punch for stamping to press the clamping blocks to deform so as to be closely clamped to the flanged plates of the radiating fins to complete quick combination of the radiating base with the radiating fins. Using the manufacturing method enables the radiating base to be thinner and lighter, extruding materials can be saved and cost can be reduced. Further, density of the radiating fins can be improved, and combination assembly of the radiating base with the radiating fins can be simplified.
Description
technical field [0001] The present invention relates to a heat sink and its manufacturing method. It mainly forms a plurality of groups of clamping blocks arranged at intervals and corresponding to each other by cutting grooves on the upper end surface of the extruded block. After the stamping clamping block is deformed, it can be Tightly clamp the heat dissipation fins to achieve the rapid combination of heat dissipation base and heat dissipation fins. Background technique [0002] In the conventional aluminum (copper) extruded heat sink, the heat dissipation base and the heat dissipation fins are integrally formed. Although the overall structure is simple, the base is relatively thick, so the consumption of consumables is large, the weight is heavy and the cost is high, and the heat dissipation fins The distance between them is relatively large, and the density of the heat dissipation fins is sparse, so the heat dissipation effect is very limited. [0003] In addition, th...
