Heat dissipation unit

Abstract

A heat dissipation unit includes a two-phase fluid hollow chamber body with a common wall face. The common wall face defines the two-phase fluid hollow chamber body with at least one first section and a second section. The first and second sections are left and right horizontally side-by-side arranged. The first section forms a vapor chamber structure and the second section forms a heat pipe structure. The two-phase fluid hollow chamber body is integrally formed and has both vapor chamber and heat pipe working performance. The heat dissipation unit can achieve both large-area heat dissipation effect and remote-end heat conduction effect. Also, the heat dissipation unit is manufactured at greatly lowered cost.
