Abstract: A user-operated air-flow regulating device includes a radiator enhancer and an enhancer extension situated adjacent to existing radiator fins of an existing baseboard radiator and oriented at an end-to-end pattern. The device further includes a mechanism for directing and displacing ambient air along a first travel path into respective cavities of the radiator enhancer and the enhancer extension. The enhancer extension includes an elongated fan and a coupling attached to one end thereof. Such a coupling is removably conjoined to a portion of the ambient air directing and displacing mechanism such that the ambient air is separately directed along the first travel path and thereafter displaced along the second travel path in each of the radiator enhancer and enhancer extension respectively. The user-operated air-flow regulating device further includes a mechanism for channeling the ambient air along a third travel path leading obliquely away from the second travel path.

Abstract: A heat-dissipating device having an air-guiding structure includes a heat-conducting seat, a fin assembly, at least one heat pipe for serially connecting to the fin assembly and the heat-conducting seat, and a fan assembly unit. The fin assembly is positioned above the heat-conducting seat and formed by arranging a plurality of heat-dissipating fins at intervals.

The air-guiding member has a guiding space for laterally communicating with the space. The air blown by the fan assembly unit can pass through the space and is received by the air-guiding member. Then, the air flow is guided to the portions to be heat-dissipated by the air-guiding member.

Abstract: A heat exchange module (1) includes a fan duct, an evaporator (22), a condenser (26) and an electric fan (50). The fan duct includes a lower portion (10) and an upper portion (30). The lower portion cooperates with the upper portion to define therebetween an air passage (90). The evaporator contains therein a working fluid. The condenser is in fluid communication with the evaporator. The evaporator and the condenser are received in the air passage defined by the fan duct. The working fluid turns into vapor in the evaporator upon receiving heat from a heat-generating component (70) and the vapor turns into condensate upon releasing the heat to the condenser. The electric fan is attached to the fan duct. The electric fan produces an airflow flowing through the air passage for removing the heat away from the condenser.
