A loop-type heat exchange device (10) is disclosed, which includes an evaporator (20), a condenser (40), a vapor conduit (30) and a liquid conduit (50). The evaporator contains therein a working fluid. The working fluid in the evaporator evaporates into vapor after absorbing heat, and the generated vapor flows, via the vapor conduit, to the condenser where the vapor releases its latent heat of evaporation and is condensed into condensate. The condensate then returns back, via the liquid conduit, to the evaporator to thereby form a heat transfer loop. The condenser defines therein a chamber, and a plurality of heat-exchange pins is provided inside the chamber for effectively exchanging heat with the vapor entering into the condenser.
