1. Field of the Invention

This invention relates to a miniaturized ice water cooling circulatory system, particularly to one able to be in stalled in a computer mainframe for lowering temperature and dissipating heat for the heating elements therein.

2. Description of the Prior Art

Referring to FIG. 1, a conventional ice water cooling circulatory system able to be used to lower temperature for the heating elements of the motherboard in a computer mainframe, such as CPU, RAM, power crystal, etc., is provided with a box 1 disposed therein with a water tank 2 having one end connected with a refrigerant input tube 3 and a refrigerant output tube 4 and another end connected with an ice-water output tube 5 and a cold-water input tube 6 respectively having the other end extended into the computer mainframe and connected with each other to be combined with the heating elements for carrying out heat dissipation for the heating elements. A water pump 7 is connected with the water tank 2 for pumping and conveying the ice water formed by the refrigerant input tube 3 into the ice-water output tube 5 to be conveyed to the interior of the computer mainframe for lowering the temperature of the heating elements on the motherboard, and then the ice water is conveyed back into the water tank 2 through the cold-water input tube 6. The refrigerant output tube 4 connected with the water tank 2 has the other end connected with a compressor 8 for compressing the refrigerant circulated, and then the compressed refrigerant is condensed by a condenser 9 and then conveyed into the water tank 2 to be circulated anew, thus achieving effect of cooling circulation. However, the water tank 2, the water pump 7 and the compressor 8 are large in size; therefore, the conventional ice water cooling circulatory system has to be installed outside a computer mainframe, thus taking too much space and spoiling integrity as well as external beauty.

This invention is advised to offer a miniaturized ice water cooling circulatory system provided with an ice water tank having a drowned water pump disposed in the interior, able to diminish the volume of the cooling circulatory system and convenient to be optionally installed in a computer mainframe to carry out heat dissipation for the heating elements in a computer mainframe. The drowned water pump has one side bored with a water intake and a water outlet and its outer circumference surrounded with at least one refrigerant conveying tube. The ice water tank has one end provided with a refrigerant input terminal and a refrigerant output terminal, and the refrigerant conveying tube has one end connected with the refrigerant input terminal and the other end connected with the refrigerant output terminal. Further, the ice water tank has another end connected with an ice-water output tube connected with water outlet, and a cold-water input tube, and the ice-water output tube and the cold-water input tube respectively have the other end connected to the heating elements of a computer mainframe. Refrigerant after sucking heat is conveyed to a compressor through the refrigerant output tube to be compressed and then conveyed to a condenser to exhaust heat and be condensed. Afterward, the condensed refrigerant is conveyed to a refrigerant controller for lowering the pressure of the refrigerant and then conveyed to the interior of the ice water tank for sucking heat therein, thus attaining effect of cooling circulation.

A first preferred embodiment of a miniaturized ice water cooling circulatory system able to be installed in a computer mainframe in the present invention, as shown in FIG. 2, mainly includes an ice water tank 10, a heat collector 20, a compressor 30, a condenser 40, a dry filter 50 and a refrigerant controller 60 combined together.

The ice water tank 10 is provided with normal temperature water and a drowned water pump 11 in the interior and has its front side bored with a water intake 111 and a water outlet 112 positioned above and communicating with the water intake 111. The drowned water pump 11 has its outer circumference disposed with a refrigerant conveying tube 13 formed into several loops surrounding the outer circumference of the drowned water pump 11. The ice water tank 10 has one end provided with a refrigerant input terminal 12 and a refrigerant output terminal 13, and the refrigerant conveying tube 113 has one end inserted in the refrigerant input terminal 12 and the other end inserted in the refrigerant output terminal 13. Further, the ice water tank 10 has its upper end connected with an external ice-water output tube 14 and a cold-water input tube 15, and the ice-water output tube 14 is extended into the ice water tank 10 to connect with the water outlet 112 and has its outer end connected with the outer end of the cold-water input tube 15.

The heat-collector 20 is a metallic board with a proper thickness to be combined with the heating members inside a computer mainframe, which need dissipating heat and lowering temperature. The heat collector 20 is formed with an input terminal 21 connected with one end of the ice-water output tube 14, and an output terminal 22 connected with one end of the cold-water input tube 15, letting the ice-water output tube 14 and the cold-water input tube 15 connected in the heat collector 20. Cold water produced after the heating elements suck heat will be conveyed back to the interior of the ice water tank 10 through the cold-water input tube 15.
