When the electronic device 1 is in operation, the heat source 40 generates heat. The liquid pump 17 can push the cooling liquid stored in the second chamber 122 of the liquid tank 12 from the second connector 182 into the second tube 62. The cold heat-dissipating liquid can flow to the cooler 50 via the second tube 62. The heat dissipating liquid in the cooler 50 is capable of absorbing heat generated by the heat source 40. Therefore, the temperature of the heat dissipating liquid rises, and the temperature of the heat source 40 decreases. The hot heat-dissipating liquid leaves the cooler 50 from the first tube 61 and flows into the first chamber 121 of the liquid tank 12 via the first connector 181.

The hot heat-dissipating liquid in the first chamber 121 can flow into the liquid supply member 13 from the liquid inlet 13a, and then flow into the flow tube 141 from the liquid supply port 13b.

The airflow generator 15 is capable of sucking a cold heat radiating airflow from the air inlet 11a to blow the heat radiating fins 142. After the heat dissipation airflow is heated by the heat dissipation fins 142, the electronic device 1 can flow out from the air outlet 11b to dissipate heat transferred from the heat dissipation liquid to the heat dissipation fins 142. Thereby, the heat-dissipating liquid flowing through the flow tube 141 can flow into the liquid-receiving member 16 from the liquid collection port 16b after the temperature is lowered. The cold heat-dissipating liquid in the liquid-receiving member 16 can flow back into the second chamber 122 of the liquid tank 12. The heat generated by the heat source 40 can be dissipated outside the electronic device 1 by the circulation of the above-described heat dissipating liquid.

Referring to FIGS. 5A and 5B, a three-dimensional flow chart of the liquid cooling module 10 in FIG. 3 with the heat dissipating component 14 is shown. When the power of the heat source 40 increases, When a set of heat dissipating components 14 is insufficient to dissipate the heat generated by the heat sink 40, the user can add the heat dissipating component 14 to the liquid cooling module 10.

As shown in FIG. 5A, the user can open the swap door 112 and insert the other set of heat dissipating components 14 into the housing 11 from the opening exposed by the drawer door 112. As shown in FIG. 5B, the flow tube 141 of the other heat dissipating component 14 is further installed in one of the liquid supply port 13b and the liquid receiving port 16b of the liquid supply member 13. In this embodiment, the two sets of heat dissipating components 14 can be adjacent to each other, but are not limited thereto. In other embodiments, the two sets of heat dissipating components 14 can also be spaced apart from one another. For example, the liquid supply member 13 and the liquid collection member 16 can each have four liquid supply ports 13b and a liquid collection port 16b. The heat dissipating component 14 of the first group can be installed in one of the four sets of liquid supply ports 13b and the liquid receiving ports 16b. The second group of heat dissipating components 14 can be installed in one of the remaining three sets of liquid supply ports 13b and liquid receiving ports 16b. The above is for illustrative purposes only and is not intended to limit the present invention. The number of the liquid supply port 13b and the liquid receiving port 16b of the present case can be greater than or equal to the number of the heat dissipating components 14. The heat dissipating component 14 is disposed at the position of the liquid supply port 13b and the liquid receiving port 16b, and can be disposed according to the needs of the user. If the two sets of heat dissipating components 14 are still insufficient to dissipate heat from the heat dissipating source 40, the heat dissipating component 14 can be additionally installed. When the power of the heat source 40 is reduced, the user can also remove the heat sink assembly 14 from the swap door 112. At this time, the valve located at the liquid supply port 13b and the liquid receiving port 16b of the heat dissipating unit 14 can be automatically or manually closed to prevent the heat dissipating liquid from flowing out. After the heat dissipation unit 14 is replaced, the door 112 can be closed.

In summary, the liquid cooling module of the present invention and the electronic device using the same The liquid cooling module can be detachably mounted on one of the plurality of liquid supply ports and one of the plurality of liquid collection ports by the flow tube of the heat dissipation component, so that the liquid cooling module can be changed according to the heat dissipation requirement of the electronic device The number of heat sink components installed. When the power of the heat source increases, the heat dissipation requirement of the electronic device increases, and the number of heat dissipation components can be increased to improve the heat dissipation efficiency of the liquid cooling module. When the power of the heat source is reduced so that the heat dissipation requirement of the electronic device is reduced, the number of heat dissipating components can also be reduced. In addition, the electronic device can also increase or decrease the number of liquid cooling modules as needed.

Although the present invention has been disclosed above in the foregoing embodiments, it is not intended to limit the present invention.
