It is the core control component of intelligent devices and automated machinery. The controller mainly includes two parts: a controller housing and a controller circuit board. The controller housing surrounds the outside of the controller circuit board to protect the controller circuit board. As the core component installation structure of the controller, the controller circuit board will generate a large amount of heat due to its operation. In order to avoid excessive heat accumulation in the controller housing, a heat dissipation structure needs to be set inside the controller.

[0003] The heat dissipation structure of traditional controllers mostly adopts an air-cooled structure setting, which relies on the air circulation formed by the cooling fan and the internal air duct to dissipate the heat. The heat dissipation effect of the air-cooled heat dissipation structure is limited. For controllers with large heat generation, when the external ambient temperature is high, relying solely on air cooling cannot meet the heat dissipation requirements of the controller. Therefore, a heat dissipation structure of the controller is proposed. Utility Model Content
