Abstract

An air deflection plug-in unit includes a housing and a flow guiding structure. The housing is provided with a first air intake vent and a first air exhaust vent, and there is an included angle between planes on which the first air intake vent and the first air exhaust vent are located. The flow guiding structure is located in the housing. The flow guiding structure is configured to guide an airflow flowing into the first air intake vent to the first air exhaust vent. This disclosure can improve a heat dissipation capability of an electronic component.
