1. A dual liquid pump liquid cooling radiator, comprising a first liquid box, second liquid box, first radiator pipe set and a second radiator pipe set, wherein:
said first radiator pipe set and said second radiator pipe set are arranged side by side between said first liquid box and said second liquid box, said first radiator pipe set and said second radiator pipe set respectively comprising a plurality of flat pipes arranged at intervals up and down and a plurality of heat dissipation fins welded on upper and lower sides of each said flat pipe, said flat pipes each having a first end thereof respectively connected to said first liquid box and an opposing second end thereof respectively connected to said second liquid box;
said first liquid box comprises an air heat insulation space therein to divide the interior of said first liquid box into a first hot liquid chamber and a first cold liquid chamber where the space of said first hot liquid chamber is smaller than the space of said first cold liquid chamber, a liquid inlet hole connected to said first hot liquid chamber, a liquid outlet hole connected to said first cold liquid chamber, and a first liquid pump set therein for making a cooling liquid flow from said liquid inlet hole through said first hot liquid chamber, then flow into the flat pipes of said first radiator pipe set, and flow to said second liquid box through the flat pipes of said first radiator pipe set, so that the said cooling liquid flowing into said second liquid box flows to said first cold liquid chamber through the flat pipes of said second radiator pipe set and then flow out of said liquid outlet hole;
said second liquid box comprises a second liquid barrier therein to divide the interior of said second liquid box into a second hot liquid chamber and a second cold liquid chamber and a second liquid pump set therein for making the said cooling liquid in the flat pipes of said first radiator pipe set flow into said second hot liquid chamber and then flow into said second cold liquid chamber, and for making the said cooling liquid in said second cold liquid chamber flow into the flat pipes of said second radiator pipe set box and then flow to said first cold liquid chamber of said first liquid box.
