1. A liquid cooler, comprising a liquid cooling head arranged on a processor, a liquid cooling radiator separated from said liquid cooling head for heat dissipation, and two liquid delivery pipes connected between said liquid cooling head and said liquid cooling radiator, wherein:
said liquid cooling radiator comprises a liquid pump box, a heat dissipation pipe set and a liquid return box, said liquid pump box comprising a box body and a box cover made of metal, said box body being integrally formed with a bottom wall, a front side wall, a rear side wall, a left side wall, a right side wall, an opening and two vertical rows of pipe jacks located on said right side wall of said box body, said heat dissipation pipe set comprising two rows of vertically arranged flat pipes and a plurality of heat dissipation fins welded on upper and lower planes of said flat pipes, each said flat pipe having one end thereof inserted and welded to one respective said pipe jack of said box body, and an opposite end thereof inserted and welded to said liquid return box;
said box body comprises an air barrier space set therein, said air barrier space having one end thereof adjacent to an inner surface of said front side wall of said box body, and an opposite end thereof bent and adjacent to an inner surface of said right side wall of said box body and located between said two rows of pipe jacks, said air barrier space dividing an inside of said box body into a hot liquid inlet chamber and a cold liquid outlet chamber, a space of said hot liquid inlet chamber being smaller than a space of said cold liquid outlet chamber, said hot liquid inlet chamber being connected to one said row of pipe jacks, and said cold liquid outlet chamber being connected to the other said row of pipe jacks, said hot liquid inlet chamber and said cold liquid outlet chamber being isolated from said air barrier space, said front side wall of said box body being provided with a liquid inlet pipe connected to said hot liquid inlet chamber and a liquid outlet pipe connected to said cold liquid outlet chamber;
said air barrier space comprises a hot liquid bending partition and a cold liquid bending partition arranged apart, said hot liquid bending partition and said cold liquid bending partition having respective one ends thereof respectively welded to an inner surface of said front side wall of said box body, respective opposite ends thereof respectively welded to an inner surface of said right side wall of said box body and between said two rows of pipe jacks and respective bottom ends thereof respectively welded to an inner surface of said bottom wall of said box body, so that said air barrier space is formed between said hot liquid bending partition and said cold liquid bending partition; and
said box cover covers the opening of said box body to seal said air barrier space, said hot liquid inlet chamber and said cold liquid outlet chamber, said box cover being in close contact with an upper end of said hot liquid bending partition and an upper end of said cold liquid bending partition.
