Abstract

An electronic device includes a housing, a liquid cooling heat dissipation assembly, and a hard drive. The liquid cooling heat dissipation assembly includes a heat exchange section, an inlet pipe, an outlet pipe, and a fin structure. The heat exchange section has an inlet channel, a bend channel, and an outlet channel. The bend channel has an inlet section, a connecting section, and an outlet section. One end of the inlet pipe and the inlet section is connected to the inlet channel. One end of the connecting section is connected to the other end of the inlet section. The connecting section and the inlet section are not parallel. One end of the outlet section is connected to the other end of the connecting section. The outlet section and the connecting section are not parallel. The other end of the outlet section and the outlet pipe are connected to the outlet channel. The width of the inlet section is greater than the width of the outlet section. The fin structure includes a first fin and a second fin. The first fin is disposed within the inlet section. The second fin is disposed within the outlet section. The hard drive is disposed within the housing.
