An integrated liquid cooling device with a heat-resisting structure, comprising an internal circulation type liquid cooling radiator, a liquid cooling head and a liquid pump, wherein:
- said internal circulation type liquid cooling radiator comprises a first liquid collection box, a second liquid collection box, a plurality of first radiator pipes and a plurality of second radiator pipes;
- said first radiator pipes and said second radiator pipes being flat metal pipes with respective two ends thereof respectively combined with said first liquid collection box and said second liquid collection box and respectively connected to the inside of said first liquid collection box and the inside of said second liquid collection box;
- said first radiator pipes and said second radiator pipes being respectively externally provided with a plurality of heat dissipation fins;
- said first liquid collection box is internally provided with an air heat insulation space, said air heat insulation space dividing the interior of said first liquid collection box into a cold liquid chamber and a hot liquid chamber;
- said cold liquid chamber comprising a cold liquid inlet for a working liquid to flow from said cold liquid chamber to said liquid cooling head, said hot liquid chamber comprising a hot liquid inlet for said working liquid to flow back from said liquid cooling head to said hot liquid chamber, said air heat insulation space being composed of a hot liquid partition and a cold liquid partition arranged inside said first liquid collection box and separated by a distance, said hot liquid partition and said cold liquid partition being welded on the inner wall of said first liquid collection box, and being located between said first radiator pipe and said second radiator pipe, so that said air heat insulation space is formed between said hot liquid partition and said cold liquid partition;
- and
- said liquid cooling head is combined on the outside of said first liquid collection box, and said liquid pump is set in said second liquid collection box to drive said working liquid in said internal circulation type liquid cooling radiator to pass through said liquid cooling head for heat absorption and heat dissipation,
- wherein said first liquid collection box comprises a first box body and a first box cover, said first box body comprising a first end and an opposing second end, the first end of said first box body being a tapered closed end, the second end of said first box body being an open end, said first box cover covering the open end of said first box body, said first box cover being provided with a plurality of first flat through holes corresponding to said first radiator pipes and said second radiator pipes;
- said liquid cooling head is fixed on the outside of said tapered closed end of said first box body of said first liquid collection box;
- said hot liquid partition and said cold liquid partition are in close contact with three inner walls of said first box body and an inner wall of said first box cover.
