Heat pipe devices and heat dissipation devices

Abstract

This disclosure provides a heat pipe device and a heat dissipation device, the heat dissipation device comprising a pipe body, a fin assembly, and a heat-conducting block. The pipe body includes a circular pipe section and a flat pipe section, the circular pipe section being formed at one end of the pipe body and the flat pipe section extending from one end of the circular pipe section. The fin assembly is disposed on the circular pipe section. The flat pipe section is attached to the heat-conducting block. The pipe body simultaneously includes the circular pipe section and the flat pipe section; the circular pipe section facilitates the connection of the fin assembly in series, and the flat pipe section can be stacked with a heat source.

Claims
