Abstract

The invention discloses a heat sink strength testing device, which includes a bottom frame, a limit block, a driving turntable, a first rotating shaft, a first coupling, a torque sensor, a second coupling, a second rotating shaft, a reducer, motor and sliding device; the lower end of the underframe is fixedly connected with a column, the top of the underframe is fixedly connected with a limit block, the end face of the limit block is provided with a first bar-shaped groove, and the driving turntable is provided with a first Two bar-shaped grooves, the first groove and the second groove are facing each other, the driving turntable is coaxially fixed with the first rotating shaft, and the first rotating shaft is connected with one end of the torque sensor through the first shaft coupling. shaft, the other end of the torque sensor is coaxially fixed with the second shaft through a second coupling, and a bearing is sleeved on the second coupling, and the output of the second shaft and the reducer The output end of the motor is connected to the input end of the reducer; the strength of the heat sink can be detected.

Description

technical field [0001] The invention relates to a heat sink strength testing device. Background technique [0002] The heat sink is a component that cools the heat-prone electronic components in electrical appliances. It is mostly made of aluminum alloy, brass or bronze into plates, sheets, and multi-sheets. For example, the CPU central processing unit in a computer needs to use a large Heat sinks, power tubes in TVs, line tubes, and power amplifier tubes in power amplifiers all use heat sinks. Generally, the heat sink should be coated with a layer of heat-conducting silicone grease on the contact surface between the electronic components and the heat sink during use, so that the heat emitted by the components can be more effectively transferred to the heat sink, and then dissipated into the surrounding air through the heat sink. [0003] In actual production, the strength of the heat sink will affect its installation and normal use. If the strength of the heat sink is not ...
