Further, the immersed phase-change liquid cooling device further comprises a pressure detection mechanism (not shown in the figure) and an alarm mechanism (not shown in the figure), wherein the pressure detection mechanism is used for detecting the pressure in the cooling liquid cavity 101, and the alarm mechanism is used for sending an alarm signal when the pressure in the cooling liquid cavity 101 exceeds a preset value. Because the coolant liquid in the liquid freezer 100 can take place the phase transition, therefore the pressure in coolant liquid chamber 101 is changing constantly, if not timely pressure release when the pressure in coolant liquid chamber 101 is too big, whole submergence formula phase transition liquid cooling device has very big safety risk, through setting up pressure detection mechanism and alarm mechanism, can send alarm signal when the pressure in coolant liquid chamber 101 exceeds the default to inform the user in time to carry out the pressure release.
Optionally, the pressure detection mechanism is a pressure sensor. The alarm mechanism can be a mechanism which can send out an alarm signal, such as an alarm lamp, a buzzer or a vibrator.
Further, the first pump body 500 and the second pump body 510 can be selectively opened and closed according to the pressure in the cooling liquid cavity 101, so that the first liquid supplementing assembly and the second liquid supplementing assembly can operate simultaneously, and the purpose of automatic pressure relief is achieved. That is to say, when the pressure in the cooling liquid cavity 101 exceeds a preset value, the control mechanism of the immersion type phase-change liquid cooling device can control the first pump 500 and the second pump 510 to be opened simultaneously, so that the cooling vapor in the cooling liquid cavity 101 is shunted to enter the first fluid infusion tank 300 and the second fluid infusion tank 310 to be liquefied respectively, and the purpose of pressure relief is achieved. When the pressure in the cooling liquid cavity 101 is reduced to a value below a safety value, the control mechanism can control to open only the first pump body 500 or the second pump body 510, so that the liquid replenishing assembly comprising the opened pump body works independently, and the purpose of reducing energy consumption is achieved.
It should be noted that, in this embodiment, the control mechanism may be a centralized or distributed controller, for example, the controller may be a single-chip microcomputer or may be composed of a plurality of distributed single-chip microcomputers, and a control program may be run in the single-chip microcomputers to control the first pump body 500, the second pump body 510, the on-off valve, the pressure detection mechanism, and the alarm mechanism to implement the functions thereof.
The working process of the immersion type phase-change liquid cooling device is described by taking only the first liquid supplementing assembly as an example:
the cooling liquid in the liquid cooling cabinet 100 first absorbs the sensible heat of the to-be-cooled member 200 and starts to rise in temperature, after the temperature of the cooling liquid rises to the phase transition temperature, the cooling liquid is gasified to form cooling steam, and then the phase transition process continues to absorb latent heat, so that the to-be-cooled member 200 is rapidly cooled. The cooling steam after completing the phase change rises and enters the first fluid infusion cavity 301 through the first steam pipeline 600, and under the action of the first fan 702, the cooling steam contacts the first cooling coil 701 and exchanges heat with the first cooling coil 701, and the cooling steam after completing the heat exchange is liquefied to form cooling fluid. The liquefied cooling liquid can flow into the liquid refrigerator 100 again through the first liquid supplementing pipeline 400 under the driving of the fluorine pump, so that the cooling liquid in the liquid refrigerator 100 can be supplemented, and the circulation is completed.
The working process of the immersed phase-change liquid cooling device is described by taking only the second liquid supplementing assembly as an example:
the cooling liquid in the liquid cooling cabinet 100 first absorbs the sensible heat of the to-be-cooled member 200 and starts to rise in temperature, after the temperature of the cooling liquid rises to the phase transition temperature, the cooling liquid is gasified to form cooling steam, and then the phase transition process continues to absorb latent heat, so that the to-be-cooled member 200 is rapidly cooled. The cooling steam after the phase change rises and enters the second fluid infusion cavity 311 through the second steam pipeline 610, and under the action of the second fan 712, the cooling steam contacts the second cooling coil 711 and exchanges heat with the second cooling coil 711, and the cooling steam after the heat exchange is liquefied to form cooling fluid. The liquefied cooling liquid can flow into the liquid refrigerator 100 again through the second liquid supplementing pipeline 410 under the driving of the fluorine pump, so as to supplement the cooling liquid in the liquid refrigerator 100, and thus the cycle is completed.
The working process of the immersed phase-change liquid cooling device is described by taking the first liquid supplementing assembly and the second liquid supplementing assembly as an example for starting simultaneously:
the cooling liquid in the liquid cooling cabinet 100 firstly absorbs the sensible heat of the to-be-cooled member 200 and starts to rise in temperature, and after the temperature of the to-be-cooled liquid rises to the phase change temperature, the cooling liquid is gasified to form cooling steam, and then, the phase change process continues to start to absorb latent heat, so that the to-be-cooled member 200 is rapidly cooled. And the cooling steam after the phase change rises and is divided, wherein part of the cooling steam enters the first fluid infusion cavity 301 through the first steam pipeline 600, and the rest of the cooling steam enters the second fluid infusion cavity 311 through the second steam pipeline 610. The cooling steam entering the first fluid replenishing cavity 301 is in contact with the first cooling coil 701 under the action of the first fan 702 and exchanges heat with the first cooling coil 701; and the cooling steam entering the second fluid infusion chamber 311 is in contact with the second cooling coil 711 under the action of the second fan 712 and exchanges heat with the second cooling coil 711. And liquefying the cooled steam after the heat exchange to form cooling liquid. The liquefied coolant can flow into the liquid refrigerator 100 again through the first liquid supplementing pipeline 400 and the second liquid supplementing pipeline 410 under the driving of the corresponding fluorine pumps, so that the supplement of the coolant in the liquid refrigerator 100 is realized, and the circulation is completed.
