Method for assembling fans and heat sinks on small scale

Abstract

The invention discloses a method for assembling fans and heat sinks on a small scale. The method is used for installing and fixing the fans on heat sinks having substrates with thickness being 1-2 millimeters. The method comprises the following steps of forming fixed holes in a heat sink substrate according to distribution positions of via holes in the fans; pressing and fixing rivets in the fixedholes; placing the fans on the heat sinks so that the via holes are opposite to the fixed holes in the heat sinks; and inserting a fixed screw into each via hole to make a screw thread fixed in the rivet. During production on a small scale, the fans can be rapidly, accurately and stably arranged and fixed on the heat sinks having substrates with thickness being 1-2 millimeters by the assembly method, no damage to a substrate structure of the heat sink is generated, the production and processing cost of an enterprise also can be greatly reduced, meanwhile, the installation time and the processing time are also saved, and the assembly and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of structural installation of electronic products, in particular to a method for assembling fans and radiators in small batches. Background technique [0002] At present, due to the structural limitation of the heat sink with thin substrate, the thickness of the substrate is very thin, and it is impossible to directly process threads on the substrate to be fixedly connected with the fan. Therefore, some radiators are installed with fan fasteners when they are installed and used with fans, which requires additional production of fan fasteners, and the production of fan fasteners requires corresponding molds and mold costs for mold development. Verifying the performance of the fan fastener and the fan's vibration reliability after installation increases the company's high manufacturing costs and product performance testing costs. Another part of the heat sink is connected with the fan by screws through the pr...

Problems solved by technology

[0002] At present, due to the structural limitation of the heat sink with thin substrate, the thickness of the substrate is very thin, and it is impossible to directly process threads on the substrate and fix it with the fan.

Therefore, some radiators are installed with fan fasteners when they are installed and used with fans, which requires additional production of fan fasteners, and the production of fan fasteners requires corresponding molds and mold costs for mold development. To verify the performance of the fan fastener and the vibration reliability of the fan after installation, which increases the company's high manufacturing costs and product performance testing costs

Another part of the heat sink is connected with the fan by screws through the processing of corrugated fins, which requires changing the fin pitch according to the screws, which may cause changes in heat dissipation performance, affect its heat dissipation performance, and also increase processing costs and processing time
