Patent ID: 7665509

Claim:
A heat exchange module comprising: an evaporator defining therein a chamber for containing a wick structure saturated with a working fluid, the wick structure occupying a portion of the chamber; a condenser disposed above the evaporator, wherein the working fluid turns into vapor in the evaporator after absorbing heat and the vapor turns into condensate at the condenser after releasing the heat; and a heat sink attached to an outer surface of the evaporator and located in alignment with the wick structure contained in the evaporator; wherein the chamber of the evaporator is divided by the wick structure into a micro-channel region filled with the wick structure and an adjacent vapor-gathering region adapted for gathering the vapor generated in the evaporator; wherein the heat exchange module further comprises a conduit connecting the evaporator with the condenser, the conduit having a first pipe section connected to said vapor-gathering region and a second pipe section connected to said micro-channel region; and wherein a wick structure is provided inside said second pipe section of said conduit.
