Heat-expelling device with a wind guide

Abstract

A heat-expelling device with a wind guide comprises a shell, a heat-generating body disposed within the front portion of the shell and a wind-blowing unit disposed within the rear portion of the shell. It further contains a wind guide at a predetermined location between the heat-generating body and the wind-blowing unit, whose outer wall includes a convex conic surface curved along the axis of and toward the heat-generating body. Thereby, the air density and the heat exchange rate can be significantly increased, and the heat generated within the heat-generating body can be delivered to the exterior of the heat-expelling device, which effectively increases the outflow air temperature and reduces the temperature of the shell.
