The water in the eventemperature water path 700 flows to thetarget equipment 900 to cool the product. The water then flows from thetarget equipment 900 to the eventemperature water path 700 to form a water circulation. The water in the eventemperature water path 700 flows through theheat exchanger 500, thehot water path 800 and therefrigerant path 600 to reduce severe temperature change to the water, such that the temperature difference of the water from the eventemperature water path 700 to thetarget equipment 900 does not change too much. However, the conventional water cooling system cannot meet specific needs for cooling wafers. - The present invention intends to provide a water cooling system which provides water of constant temperature to target equipment.

FIG. 2 shows another embodiment of the water cooling system of the present invention, and -
FIG. 3 shows the conventional water cooling system. - Referring to
FIG. 1 , thewater cooling system 10 of the present invention comprises atemperature control device 1, afirst heat exchanger 2, afirst tank 3, afirst pump 4, asecond heat exchanger 5, asecond tank 6, and asecond pump 7. Thefirst heat exchanger 2 includes ahot water path 21, arefrigerant path 22 and an eventemperature water path 23. The two ends of thehot water path 21 are respectively connected to thetemperature control device 1, and the two ends of therefrigerant path 22 are respectively connected to thetemperature control device 1 as well. The eventemperature water path 23 includes an eventemperature water outlet 231 and an eventemperature water inlet 232. Thefirst pump 4 is connected between thefirst tank 3 and the eventemperature water inlet 232 so as to pump the water in thefirst tank 3. Thesecond heat exchanger 5 includes a watertemperature control path 51 and a constanttemperature water path 52. The watertemperature control path 51 includes afirst inlet 511 and afirst outlet 512. Thefirst inlet 511 is connected to the eventemperature water outlet 231, and thefirst outlet 512 is connected to thefirst tank 3. The constanttemperature water path 52 includes a constanttemperature water outlet 522 and a constanttemperature water inlet 521. Atarget equipment 200 is connected between the constanttemperature water outlet 522 and thesecond tank 6. Thesecond pump 7 is connected between thesecond tank 6 and the constanttemperature water inlet 521 so as to pump the water in thesecond tank 6. - When the
water cooling system 10 operates, thetemperature control device 1 controls the temperature of therefrigerant path 22 and the eventemperature water path 23 so that the water in the eventemperature water path 23 reaches a pre-set temperature via thefirst heat exchanger 2, thehot water path 21 and therefrigerant path 22. The water in the eventemperature water path 23 flows through the watertemperature control path 51 and enters into thefirst tank 3. Thefirst pump 4 pumps the water in thetank 3 to the eventemperature water path 23 to form a circulation. - The
second pump 7 pumps the water in thesecond tank 6 to the constanttemperature water path 52, and the water in the constanttemperature water path 52 flows through thesecond heat exchanger 5 to proceed heat exchange with the water in the watertemperature control path 51 so that the water from the constanttemperature water path 52 keeps the pre-set temperature and flows to thetarget equipment 200. The water in thetarget equipment 200 then flows back to thesecond tank 6. There aremultiple temperature sensors 8 installed to the eventemperature water outlet 231, thefirst outlet 512, the constanttemperature water outlet 522, a position of thetarget equipment 200 where water leaves from thetarget equipment 200, and thefirst tank 3. Thetemperature control device 1 judges the water temperature by thesemultiple temperature sensors 8 so as to control thehot water path 21 and therefrigerant path 22. Themultiple temperature sensors 8 send signals back to thetemperature control device 1 by way of wireless transmission or cable transmission. Thetemperature control device 1 can also include condensation unit, compressor, heater and hot pump to control thehot water path 21 and therefrigerant path 22. - The water temperature is stable by using the
first heat exchanger 2 to proceed heat exchange to the water in thehot water path 21 and therefrigerant path 22. The water in the constanttemperature water path 52 flows through thesecond heat exchanger 5 to proceed heat exchange with the water in the watertemperature control path 51 so that the water from the constanttemperature water path 52 keeps the pre-set temperature and flows to thetarget equipment 200. That is to say, the water that flows to thetarget equipment 200 is proceeded by two times of heat exchange so that the temperature of the water to the target equipment is more stable than that of the conventional water cooling system. The water temperature proceeded by the conventional water cooling system can be controlled within a range of positive 0.1 to minus 0.1 degrees Celsius. The water temperature proceeded by thewater cooling system 10 of the present invention can be controlled within a range of positive 0.05 to minus 0.05 degrees Celsius. - As shown in
FIG. 2 , aswitch 9 is connected between the constanttemperature water inlet 521 and thesecond pump 7. Theswitch 9 checks water flowing through theswitch 9 and sends a signal to thetemperature control device 1 to confirm that thesecond pump 7 pumps water to the constanttemperature water path 52. By this way, the operation between thesecond pump 7 and the constanttemperature water path 52 can be monitored, for example, thesecond pump 7 fails to operate or the second pump is stocked. The communication between theswitch 9 and thetemperature control device 1 can be cabled or wireless. Arelease valve 100 is connected between thesecond pump 7 and thesecond tank 6 to form arelease path 101. When thesecond pump 7 pumps the water in thesecond tank 6 to the constanttemperature water path 52, a portion of the water pumped by thesecond pump 7 flows back to thesecond tank 6 by the settings or therelease valve 100 so as to control water pressure of the water from thesecond pump 7 to the constanttemperature water path 52. Another portion of the water pumped by thesecond pump 7 flows to theswitch 9. This is able to control the water pressure of the water that flows from thesecond pump 7 to the constanttemperature water path 52, and to control the water pressure of the water that flows from constanttemperature water path 52 to thetarget equipment 200. By this arrangement, thesecond heat exchanger 5 and thetarget equipment 200 are protected from being damaged by high pressure. - Besides, the
second heat exchanger 5 includes areservoir 53 which is filled with heat-conductive agent (not shown) and vacuumed. By this arrangement, the efficiency of thesecond heat exchanger 5 is improved. The heat-conductive agent can be refrigerant or water. - The
water cooling system 10 further comprises a three-way valve 110 and a check valve 20. The three-way valve 110 includes avalve inlet 111, a valvefirst outlet 112 and a valvesecond outlet 113. Thevalve inlet 111 is connected with the eventemperature water outlet 231. The valvefirst outlet 112 is connected with thefirst inlet 511 of the watertemperature control path 51. The valvesecond outlet 113 is connected with thefirst tank 3. Thecheck valve 120 includes anentrance 121 and anexit 122, wherein theentrance 121 is connected with thefirst outlet 512 of the watertemperature control path 51, and theexit 122 is connected with thefirst tank 3. The three-way valve 110 controls water volume from the eventemperature water outlet 231 to thefirst inlet 511 of the watertemperature control path 51 according to settings of thetemperature control device 1. Therefore, for a portion of the water that does not flow to thefirst inlet 511, the three-way valve 110 controls water volume from the valvesecond outlet 113 to thefirst tank 3 so that water cannot flows from theexit 122 to theentrance 121 of thecheck valve 120. The three-way valve 110 is able to control the water volume to the watertemperature control path 51 so that the temperature difference of the water to thetarget equipment 200 is further minimized. Thecheck valve 120 prevents the water from the valvesecond outlet 113 from flowing back tofirst outlet 512 of the watertemperature control path 51 to affect the water temperature to thetarget equipment 200. Thetemperature control device 1 controls the three-way valve 110 by the signals feedback from thetemperature sensors 8, for example, thetemperature sensor 8 of thefirst tank 3 sends signals of water temperature back to thetemperature control device 1. Thetemperature sensor 8 may be installed at thefirst outlet 512 of the watertemperature control path 51, and thetemperature sensor 8 is located between thefirst outlet 512 of the watertemperature control path 51 and theentrance 121 of thecheck valve 120. - While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
