Water-cooling radiator

Abstract

A water-cooling radiator with staggered-overlap heat-dissipation fins includes a main body, which is provided with a heat-dissipation fin assembly, a coolant tube, a water inlet and a water outlet. An end of the coolant tube is connected with the water inlet, and the other end of the coolant tube is connected with the water outlet. The heat-dissipation fin assembly is composed of two heat-dissipation fin groups connected in an inverse overlap manner, and the two heat-dissipation fin groups are the same in fin spacing.

What is claimed is: 
     
         1 . A water-cooling radiator, comprising:
 a main body;   wherein the main body is provided with a heat-dissipation fin assembly, a coolant tube, a water inlet and a water outlet; a first end of the coolant tube is connected to the water inlet, and a second end of the coolant tube is connected to the water outlet; the heat-dissipation fin assembly is composed of two heat-dissipation fin groups connected in an inverse overlapping manner; and the two heat-dissipation fin groups are the same in fin spacing.   
     
     
         2 . The water-cooling radiator of  claim 1 , wherein the two heat-dissipation fin groups are made of a nickel-plated aluminum alloy; each of the two heat-dissipation fin groups has a waveform structure; and crests of one of the two heat-dissipation fin groups are symmetrical with crests of the other of the two heat-dissipation fin groups one by one. 
     
     
         3 . The water-cooling radiator of  claim 1 , wherein a fin spacing of each of the two heat-dissipation fin groups is 3 mm. 
     
     
         4 . The water-cooling radiator of  claim 1 , wherein the main body is provided with an upper cover and a lower cover; a first water tank and a second water tank are provided between the upper cover and the lower cover; and the coolant tube is provided between the first water tank and the second water tank. 
     
     
         5 . The water-cooling radiator of  claim 4 , wherein the coolant tube is a hollow aluminum tube; and the coolant tube is communicated with the first water tank and the second water tank. 
     
     
         6 . The water-cooling radiator of  claim 4 , wherein an inner side of a middle of the first water tank is provided with a blocking plate; the first water tank is connected with the water inlet and the water outlet; and the water inlet is located at one side of the blocking plate, and the water outlet is located at the other side of the blocking plate. 
     
     
         7 . The water-cooling radiator of  claim 4 , wherein two sides of the coolant tube are each provided with the heat-dissipation fin assembly. 
     
     
         8 . The water-cooling radiator of  claim 4 , wherein the upper cover is provided with a water-filling plug.
