In this embodiment, the liquid-coolingheat dissipating module 1 comprises a water-coolingradiator 11, a water-coolinghead assembly 12 and anexternal pump 13. The water-coolingradiator 11, the water-coolinghead assembly 12 and theexternal pump 13 are in fluid communication with each other to define a sealed circulating loop. Moreover, a fluidic medium (not shown) is filled in the sealed circulating loop. As the fluidic medium flows within the sealed circulating loop, heat energy is transmitted from a higher temperature site to a lower temperature site of the liquid-coolingheat dissipating module 1. Consequently, the temperature at the higher temperature site is effectively decreased. - In this context, the
external pump 13 is a pump unit that is independently and individually operated. Theexternal pump 13 comprises ahousing 130, apump inlet 132, apump outlet 133 and a fluid pusher (not shown). A sealed space for accommodating the fluidic medium is defined by thehousing 130. The sealed space is asecond chamber 131. Thesecond chamber 131 will be described later. - The water-cooling
head assembly 12 is attached on aheat source 8 of an external object 9 (seeFIG. 2 ). After the heat from theheat source 8 is absorbed by the water-coolinghead assembly 12, the heat is transferred to the water-coolingradiator 11 through the fluidic medium. Due to the heat exchange of the water-coolingradiator 11, the temperature is decreased. Moreover, the water-coolinghead assembly 12 comprises a water-coolinghead 121 and abracket 122. Thebracket 122 is contacted with the water-coolinghead 121. When thebracket 122 is fixed on theexternal object 9 by screwing means, the water-coolinghead 121 is clamped between thebracket 122 and theobject 9. In this embodiment, the water-coolinghead 121 has aflat bottom surface 1210. Theflat bottom surface 1210 is contacted with theheat source 8 of theobject 9. By means of the large-area contact, the heat exchange between the liquid-coolingheat dissipating module 1 and theheat source 8 of theobject 9 is achieved quickly. - Please refer to

Thefirst chamber 1211, thehead inlet 1212 and thehead outlet 1213 are in fluid communication with each other. The water-coolinghead 121 is connected with theexternal pump 13 through thehead inlet 1212 in order to receive the fluidic medium from theexternal pump 13. The water-coolinghead 121 is connected with the water-coolingradiator 11 through thehead outlet 1213 in order to transmit the fluidic medium to the water-coolingradiator 11. - Please refer to

The two ends of thepump tube 134 are connected with thepump outlet 133 and thehead inlet 1212, respectively. Consequently, the water-coolinghead 121 and theexternal pump 13 are in fluid communication with each other. The fluidic medium flows in the direction from theexternal pump 13 to the water-coolinghead 121. -
FIG. 5 is a schematic cross-sectional view illustrating the water-cooling radiator of the liquid-cooling heat dissipating module according to the first embodiment of the present invention. Please refer toFIGS. 2 and 5 . The water-coolingradiator 11 comprises a radiatorinner channel 110, aradiator outlet tube 111 and aradiator inlet tube 112. The radiatorinner channel 110, theradiator outlet tube 111 and theradiator inlet tube 112 are in fluid communication with each other. Thehead outlet 1213 of the water-coolinghead 121 is connected with theradiator inlet tube 112 of the water-coolingradiator 11. After the heated fluidic medium having the higher temperature is outputted from the water-coolinghead 121, the fluidic medium is introduced into the water-coolingradiator 11 through theradiator inlet tube 112. Due to the heat exchange of the water-coolingradiator 11, the temperature of the fluidic medium is decreased. Moreover, theradiator outlet tube 111 is connected with thepump inlet 132 of theexternal pump 13. After the temperature of the fluidic medium is decreased by the water-coolingradiator 11, the fluidic medium is introduced into theexternal pump 13 through the water-coolingradiator 11. Then, the fluidic medium in theexternal pump 13 is pressurized and pushed to the water-coolinghead 121. Consequently, the fluidic medium can circularly flows within the liquid-coolingheat dissipating module 1. - Please refer to
FIG. 5 again. The radiatorinner channel 110 comprises a leftcommunication channel part 110 a, a rightcommunication channel part 110 b, anupper chamber 110 c and alower chamber 110 d.

Theradiator outlet tube 111 is in communication with theupper chamber 110 c. The two ends of the leftcommunication channel part 110 a are connected with theupper chamber 110 c and thelower chamber 110 d, respectively. The two ends of the rightcommunication channel part 110 b are connected with theupper chamber 110 c and thelower chamber 110 d, respectively. After the fluidic medium is introduced into thelower chamber 110 d through theradiator inlet tube 112, the fluidic medium separately flows toward the left side and the right side to theupper chamber 110 c through the leftcommunication channel part 110 a and the rightcommunication channel part 110 b. The flowing directions of the fluidic medium are indicated by the arrows as shown inFIG. 5 . After the fluidic medium is outputted from theupper chamber 110 c, the fluidic medium is transmitted to theexternal pump 13 though theradiator outlet tube 111. - As shown in
FIG. 2 , the liquid-coolingheat dissipating module 1 further comprises twofan modules 19. The twofan modules 19 are arranged beside the leftcommunication channel part 110 a and the rightcommunication channel part 110 b, respectively. The twofan modules 19 are used for creating airflow and guiding the airflow toward the leftcommunication channel part 110 a and the rightcommunication channel part 110 b, respectively. By the airflow, the heat of the fluidic medium in the water-coolingradiator 11 is quickly dissipated to the surroundings. Consequently, the heat dissipating efficiency is enhanced. - As mentioned above, the fluidic medium flows within the sealed circulating loop. After the fluidic medium flows through the
first chamber 1211, thehead outlet 1213, theradiator inlet tube 112, thelower chamber 110 d, thecommunication channel parts 110 a/110 b, theupper chamber 110 c, theradiator outlet tube 111, thepump inlet 132, thesecond chamber 131, thepump outlet 133, thepump tube 134 and thehead inlet 1212 sequentially, the fluidic medium returns back to thefirst chamber 1211. - Please refer to

After the position-limitingelement 123 is connected with thebracket 122, a clamping space is defined by the position-limitingelement 123 and thebracket 122 collaboratively, and theexternal pump 13 is accommodated within the clamping space. That is, theexternal pump 13 is clamped and positioned by the position-limitingelement 123 and thebracket 122. By the position-limitingelement 123, the two independent components (i.e., theexternal pump 13 and the water-cooling head assembly 12) are contacted with each other. Consequently, the volume (i.e., the occupied space) of the liquid-coolingheat dissipating module 1 is effectively reduced. - Moreover, two bent supporting
structures 1220 are extended from thebracket 122 in the direction away from thefirst chamber 1211. The position-limitingelement 123 comprises a middlepressing part 1230 and twocoupling parts 1231. The twocoupling parts 1231 are respectively located at two ends of the middlepressing part 1230. Theexternal pump 13 is covered and pressed by the middlepressing part 1230 of the position-limitingelement 123. Moreover, the twocoupling parts 1231 of the position-limitingelement 123 are fixed on the two bent supportingstructures 1220 by screwing means.

bracket 122 is an I-shaped bracket. Thebracket 122 comprises amiddle supporting segment 1221 and two lateral supportingsegments 1222.

The water-coolingradiator 21, the water-coolinghead assembly 22 and theexternal pump 23 are in fluid communication with each other to define a sealed circulating loop. Moreover, a fluidic medium (not shown) is filled in the sealed circulating loop. As the fluidic medium flows within the sealed circulating loop, heat energy is transmitted from a higher temperature site to a lower temperature site of the liquid-coolingheat dissipating module 2. Consequently, the temperature at the higher temperature site is effectively decreased. - Similarly, water-cooling
head assembly 22 is attached on anexternal object 9′. After the heat from theobject 9′ is absorbed by the water-coolinghead assembly 22, the heat is transferred to the water-coolingradiator 21 through the fluidic medium and dissipated away by the water-coolingradiator 21.

That is, when theexternal pump 23 and the water-coolinghead 221 are directly coupled with each other, theexternal pump 23 and the water-coolinghead assembly 22 are combined together.
