Abstract

A water cooling radiator includes a water pump assembly and a water drain assembly. The water pump assembly includes a base and a housing spliced with the base to form an accommodating cavity. A water inlet portion and a water outlet portion in the accommodating cavity are formed on the base. The water inlet portion includes a water inlet tank provided on the base, a water inlet pump arranged in the water inlet tank and connected with the base, and a water inlet nozzle connected to the base and communicated with the water inlet tank. The water inlet tank is communicated with the water drain assembly. The water outlet portion includes a water outlet tank provided on the base, a water outlet pump arranged in the water outlet tank and connected with the base, and a water outlet nozzle connected to the base and communicated with the water outlet tank.

Claims (10)

1. A water cooling radiator, comprising a water pump assembly and a water drain assembly connected to the water pump assembly, wherein the water pump assembly comprises a base and a housing spliced with the base to form an accommodating cavity, and a water inlet portion and a water outlet portion located in the accommodating cavity are formed on the base; the water inlet portion comprises a water inlet tank provided on the base, a water inlet pump arranged in the water inlet tank and connected with the base, and a water inlet nozzle connected to the base and communicated with the water inlet tank; the water inlet tank is communicated with the water drain assembly; the water outlet portion comprises a water outlet tank provided on the base, a water outlet pump arranged in the water outlet tank and connected with the base, and a water outlet nozzle connected to the base and communicated with the water outlet tank; and the water inlet tank and the water outlet tank are arranged in parallel, and the water inlet nozzle and the water outlet nozzle are arranged in parallel;

wherein the base is provided with a water inlet and a water outlet communicated with the water drain assembly, the water inlet is located in the water inlet tank, and the water outlet is located in the water outlet tank; and

wherein the base is further provided with a water outlet groove communicated with the water outlet nozzle, which is communicated with the water outlet tank and the water drain assembly, the base is provided with a water outlet deflector for closing an end of the water outlet groove communicated with the water drain assembly, the base is further provided with a water inlet groove communicated with the water inlet nozzle, which is communicated with the water inlet tank and the water drain assembly, and the base is provided with a water inlet deflector for closing an end of the water inlet groove communicated with the water drain assembly.

2. The water cooling radiator of claim 1 , wherein the water inlet pump comprises a water inlet rotor housing, a water inlet impeller rotatably connected with the water inlet rotor housing, and a water inlet stator arranged on the water inlet rotor housing away from the water inlet impeller, and the water inlet impeller comprises a water inlet rotating portion and a water inlet turbine portion that is located at a tank bottom of the water inlet tank; and the water outlet pump comprises a water outlet rotor housing, a water outlet impeller rotatably connected with the water outlet rotor housing, and a water outlet stator arranged on the water outlet rotor housing away from the water outlet impeller, and the water outlet impeller comprises a water outlet rotating portion and a water outlet turbine portion that is located at a tank bottom of the water outlet tank.

3. The water cooling radiator of claim 1 , wherein the water drain assembly comprises an upper water chamber having a water collection cavity and communicated with the base, a partition plate partitioning the water collection cavity into a water inlet cavity and a water outlet cavity is arranged in the upper water chamber, the water inlet cavity is communicated with the water inlet tank, and the water outlet cavity is communicated with the water outlet tank.
