Device and method for absorbing and radiating heat in very small space

摘要

A heat absorbing and radiating device includes a driving unit (11) having communicable first fluid outlets (52) and fourth fluid inlets (55), a heat-exchange unit (121) communicating at an end with third fluid outlets (54) of the driving unit (11) and at another end with an inlet end of a liquid-gas confluence unit (13), which communicates at an outlet end with an inlet end of a liquid-gas separation chamber (14), while the latter communicates at an outlet end with one of two second fluid inlets (53) of the driving unit (11). The driving unit (11) is provided therein with reciprocatingly movable magnets (16,17,18) to alternately push first and second fluids into the heat-exchange unit (121) before they enter the fluid-gas confluence unit (13), so that hot air is finally released from the liquid-gas separation chamber (14). Since radiating fins and cooling fan are omitted, the device has reduced volume for use with a heat source in a small space, such as a CPU of a portable computer.
