Employees take the radiator on the belt line, pay attention to check whether there is any foreign matter in the thermal grease on the radiator and whether the thermal paste is evenly applied, and fix the electrical box and the radiator with screws, and check again whether there are any foreign matter, scratches and other hidden dangers in the thermal grease on the radiator.

[0040] like Fig. 9 As shown in the figure, in the current production process of the electronics industry, electrical components will emit huge amounts of heat during operation. If the heat cannot be conducted away in time, once the heat accumulates, it will lead to the hidden danger of failure of the electrical components. To solve this problem, the current industry generally adopts adding a heat sink and using a heat sink to fill the gap. The heat sink is used to conduct the heat emitted by the power module to the heat sink, so that the temperature of the power module is maintained at a level that can work stably, preventing the power module from being damaged due to poor heat dissipation, and extending the service life of the power module.

The employee takes the radiator on the belt line, pays attention to check whether there are any foreign objects on the heat sink and whether the thermal paste is evenly applied, the employee fixes the electrical box and the radiator with screws, and again checks whether there are any foreign objects, scratches and other hidden dangers on the heat sink.
