[0019] See also Figure 1 In an embodiment of the utility model, a cold plate server heat dissipation system device includes an outdoor cold source machine 1, an indoor intermediate heat exchange unit 2, a cold plate server terminal 3, a first refrigerant pipeline 107 and a third refrigerant pipeline 206, the cold plate server terminal 3 includes a plurality of server liquid cold plates 301 for dissipating heat to the server, the cold plate server terminal 3 and the indoor intermediate heat exchange unit 2 are connected through the third refrigerant pipeline 206 to circulate heat to the server liquid cold plate 301, and the indoor intermediate heat exchange unit 2 and the outdoor cold source machine 1 are connected through the first refrigerant pipeline 107 to circulate heat to the indoor intermediate heat exchange unit 2.
[0020] The indoor intermediate heat exchange unit 2 includes a plate heat exchanger 203 and a fin coil heat exchanger 202. The third refrigerant pipeline 206 connects the server liquid cooling plate 301 and the plate heat exchanger 203 as a refrigerant circulation pipeline, so that the refrigerant circulates between the server liquid cooling plate 301 and the plate heat exchanger 203. A second filter 207 is installed on the third refrigerant pipeline 206 at the input end of the plate heat exchanger 203, and a second liquid cooling pump 205 is installed on the third refrigerant pipeline 206 between the second filter 207 and the plate heat exchanger 203. A second electric three-way valve 204 is installed on the third refrigerant pipeline 206 at the output end of the plate heat exchanger 203.
[0021] The fin coil heat exchanger 202 is provided with a second fan 201 for heat dissipation, and the input and output ends of the fin coil heat exchanger 202 are both installed with a fourth refrigerant pipeline 208. The fourth refrigerant pipeline 208 at the output end of the fin coil heat exchanger 202 is installed on the third refrigerant pipeline 206 at the input end of the second filter 207, and the fourth refrigerant pipeline 208 at the input end of the fin coil heat exchanger 202 is connected to the second electric three-way valve 204.
[0022] The outdoor cold source machine 1 includes a condensing cooling coil assembly 102 and a heat exchanger 106. The condensing cooling coil assembly 102 is provided with a first fan 101 for heat dissipation. The first refrigerant pipeline 107 connects the condensing cooling coil assembly 102 and the plate heat exchanger 203 as a refrigerant circulation pipeline, so that the refrigerant circulates between the condensing cooling coil assembly 102 and the plate heat exchanger 203. A first filter 110 is installed on the first refrigerant pipeline 107 at the output end of the plate heat exchanger 203, a first liquid cooling pump 109 is installed on the first refrigerant pipeline 107 on the output side of the first filter 110, and a first electric three-way valve 108 is installed on the first refrigerant pipeline 107 on the output side of the first liquid cooling pump 109.
[0023] The output end and output end of the heat exchanger 106 are both installed with a second refrigerant pipeline 111. The second refrigerant pipeline 111 at the input end of the heat exchanger 106 is connected to the first electric three-way valve 108, and the second refrigerant pipeline 111 at the output end of the heat exchanger 106 is connected to the first refrigerant pipeline 107 at the input end of the plate heat exchanger 203.
[0024] A refrigerant pipeline 103 is arranged between the heat exchanger 106 and the condensing cooling coil assembly 102. The refrigerant pipeline 103 connects the heat exchanger 106 and the condensing cooling coil assembly 102 to form a refrigerant circulation pipeline. The refrigerant circulates in the condensing cooling coil assembly 102, the refrigerant pipeline 103 and the heat exchanger 106. A compressor 104 is installed on the refrigerant pipeline 103 at the output end of the heat exchanger 106, and an expansion valve 105 is installed on the refrigerant pipeline 103 at the input end of the heat exchanger 106.
[0025] In the outdoor high temperature environment, the automatic program issues a command to switch the first refrigerant to the heat exchanger 106 through the first electric three-way valve 108 for heat exchange. At the same time, the compressor 104 is turned on, and the compression refrigeration cycle starts to work. The refrigerant exchanges heat with the first refrigerant in the heat exchanger 106. The cooled first refrigerant exchanges heat with the plate heat exchanger 203 through the second refrigerant pipeline 111 and the first refrigerant pipeline 107. The first refrigerant that absorbs heat is transported to the heat exchanger 106 through the first liquid cooling pump 109 for heat exchange. At this point, the heat exchange of the first refrigerant heat dissipation cycle is completed, and then the next heat exchange cycle is entered.
[0026] After the second refrigerant is cooled in the plate heat exchanger 203, a portion of the second refrigerant absorbs the heat generated by the server operation in the server liquid cooling plate 301 connected to the third refrigerant pipeline 206, and is then transported to the plate heat exchanger 203 by the second liquid cooling pump 205 for heat exchange. A portion of the second refrigerant cools the air that has absorbed the remaining heat through the server through the fin coil heat exchanger 202. The cooled air is transported to the air inlet of the cold plate server terminal 3 through the second fan 201 for the next heat exchange process. After absorbing the heat, this portion of the second refrigerant passes through the fourth refrigerant pipeline 208 and merges with the second refrigerant from the server liquid cooling plate 301 and returns to the plate heat exchanger 203 for heat exchange. At this point, the heat exchange is completed by the heat dissipation cycle of the second refrigerant.
[0027] In the outdoor low temperature environment, the automatic program issues an instruction to switch the first refrigerant through the first electric three-way valve 108 to the condensing cooling coil assembly 102 for heat exchange. At the same time, the compressor 104 stops running, and the compression refrigeration cycle stops running. The first refrigerant exchanges heat with the outdoor low temperature air through the condensing cooling coil assembly 102. The cooled first refrigerant exchanges heat with the plate heat exchanger 203 through the first refrigerant pipeline 107. The first refrigerant after absorbing heat is transported to the condensing cooling coil assembly 102 through the first liquid cooling pump 109 for heat exchange. At this point, the heat exchange of the first refrigerant heat dissipation cycle is completed, and then enters the next heat exchange cycle. The second refrigerant can be heat exchanged according to the heat dissipation cycle in the outdoor high temperature environment.
[0028] Two or more indoor intermediate heat exchange units 2 can be connected in parallel through the first refrigerant pipeline 107, and the indoor intermediate heat exchange unit 2 can be connected to one or more cold plate server terminals 3 to supply the second refrigerant cooling capacity thereto. The first refrigerant is preferably an alcohol aqueous solution, and the second refrigerant is preferably a non-conductive electronic coolant, so as to avoid any impact on the server when a pipeline component leaks.
[0029] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
