Claim:
1. A liquid cooling heat dissipation structure, comprising: a heat-conducting substrate having a heat-conducting body contacting a heat generation source and a plurality of heat-dissipating fins disposed on the heat-conducting body; a fluid-splitting board disposed on the heat-dissipating fins; a fluid-conducting board disposed on the fluid-splitting board; and a liquid supply module including an external cover body detachably disposed on the heat-conducting body and at least two pumps detachably disposed on the external cover body, wherein the heat-dissipating fins, the fluid-splitting board, and the fluid-conducting board are received inside the external cover body; wherein the fluid-conducting board has at least two first fluid-conducting openings respectively corresponding to the at least two pumps and a second fluid-conducting opening communicated with the at least two first fluid-conducting openings through a first receiving space, and the fluid-splitting board has a first fluid-splitting opening communicated with the second fluid-conducting opening through a second receiving space and a second fluid-splitting opening communicated with the first fluid-splitting opening through a third receiving space; wherein the external cover body has at least one liquid inlet communicated with the at least two first fluid-conducting openings through a fourth receiving space and at least one liquid outlet communicated with the second fluid-splitting opening through a fifth receiving space, and cooling liquid flows into the external cover body through the at least one liquid inlet and flows out of the external cover body through the at least one liquid outlet by driving one or all of the at least two pumps.
