Heat dissipating device with forced coolant and air flow

摘要

A heat dissipating device (1) comprises a heat-conductive container (10), a heat sink (20), and an electric pump (30). The container defines a containing channel therein, a first inlet (17) and a first outlet (16) at opposite ends of the containing channel. The heat sink comprises a plurality of fins (21) and a heat pipe (23) extending through the fins. One end of the heat pipe is connected to the first outlet. The electric pump (30) has a second inlet (32) and a second outlet (34). The second inlet is connected to an opposite end of the heat pipe. The second outlet is connected to the first inlet. Thereby a hermetic loop is formed. Liquid coolant (not shown) is received in the hermetic loop and flows under driving force of the pump. Further, a fan is mounted to a side of the heat sink to provide forced convection.
