Abstract: A loop-type heat exchange module (10) is disclosed, which includes an evaporator (11), a vapor conduit (12), a condenser (13), a liquid conduit (14), a cooling fan (16), a fastening seat (151) and a fan cover (152). The evaporator contains therein a working fluid. The working fluid evaporates into vapor after absorbing heat in the evaporator, and the generated vapor flows, via the vapor conduit, to the condenser where the vapor releases the heat 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 cooling fan is applied to produce a forced airflow towards the condenser. The fastening seat is used for fastening the evaporator to have an intimate contact with a heat-generating electronic component. The fan cover extends from one side of the fastening seat and receives the cooling fan and the condenser therein.
