When the coolant is heated, it evaporates in the evaporation space and absorbs a large amount of heat. The evaporated gas enters the condenser through the air supply pipe and is reliquefied.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The present invention provides a passive protection component on the inner side of the liquid-cooled shell. After the electronic device body is installed above the liquid-cooled seat, four groups of high thermal conductivity ceramic plates are respectively in contact with the outer ends of the electronic device body, and two groups of ceramic top frames are connected to protect the top of the electronic device. The passive protection layer composed of the high thermal conductivity ceramic plates and the ceramic top frames effectively isolates heat and prevents heat from accumulating inside the device, thereby reducing the risk of thermal runaway and the probability of thermal runaway. When facing thermal runaway, the passive protection layer can quickly and effectively control the thermal runaway of the battery cell and hinder heat diffusion, prevent the coolant from directly contacting the sensitive components of the electronic device body, avoid potential corrosion or damage, and ensure that the temperature distribution of various parts inside the electronic device is more uniform. The passive protection layer can effectively prevent the leakage of the coolant and improve the stability and reliability of the electronic device body. The design of immersion in flame-retardant coolant combined with the passive protection layer can better ensure the safe operation of the electronic device body under extreme conditions.

[0028] 2. The present invention provides a heat transfer uniformity component on the inner side of the liquid cooling shell. When the liquid cooling device is in use, the working heat of the electronic device body is quickly absorbed by the cooling liquid, the reflux water pump works to make the liquid flow and bring the heat into the cooling box, and when the temperature sensor detects that the heat conduction distribution inside the electronic device body is uneven, the heat transfer uniformity component works, the baffle blocks the low temperature side to change the flow path and flow rate of the coolant to achieve rapid cooling of the high thermal conductivity ceramic plate on the high temperature side by the coolant, the flow rate and flow path of the coolant are adjusted in real time to achieve uniform distribution of the coolant, and the coolant flow rate in the high heat load area of ​​the electronic device body is increased to achieve uniform distribution on the high thermal conductivity ceramic plate, thereby improving the heat dissipation performance and service life of the liquid cooling device.

[0029] 3. The present invention installs a condenser on the top of the external seat. When the temperature of the coolant is higher than a preset value, the reflux water pump stops running, and the coolant in the liquid-cooled shell continues to heat up. When the coolant is heated, it evaporates in the evaporation space and absorbs a large amount of heat. Compared with traditional air cooling or liquid cooling technology, evaporative cooling can take away the heat generated by the electronic device body more quickly, thereby achieving efficient heat dissipation effect. Evaporative cooling technology effectively prevents leakage of the liquid cooling layer. Since evaporative cooling can maintain a stable temperature inside the liquid-cooled shell, it helps to reduce electronic device body failures caused by overheating, improves the stability and reliability of the liquid cooling device, and is suitable for cooling and heat dissipation needs under various environmental conditions. The evaporated gas enters the condenser through the air supply pipe and is re-liquefied, thereby realizing the recycling of the coolant vapor.

[0030] 4. The present invention installs a cooling box on the outside of the liquid-cooled shell. When the coolant flows back into the cooling box, the water-based detergent and the preservative purify and preservative the coolant. The water-based detergent can effectively remove oil, dust and other organic pollutants in the coolant, improve the cleanliness and transparency of the coolant, and extend its service life. The preservative is added to prevent corrosion of water path components. The anticorrosive can form a protective film on the inner surface of the component to prevent direct contact between the coolant and metal and other materials. Adding the anticorrosive can prevent the coolant from causing corrosion and damage to the components inside the liquid cooling device, thereby ensuring the stable operation of the liquid cooling device and increasing the service life of the liquid cooling device.

[0045] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 , an embodiment provided by the present invention: a liquid cooling device with high safety and a cooling method thereof;

[0046] It includes a liquid cooling seat 1, a liquid cooling shell 2 and a high thermal conductivity ceramic plate 3. The liquid cooling shell 2 is installed on the top of the liquid cooling seat 1. The bottom of the liquid cooling seat 1 is symmetrically provided with a horizontal adjustment groove 9. A horizontal sinking groove 10 is provided on the inner wall of one side of the horizontal adjustment groove 9. A fixing plate 11 is installed on the inner side of the horizontal sinking groove 10. A threaded rod 12 is installed between the fixing plate 11 and the inner wall of the horizontal adjustment groove 9. A driving seat 14 is sleeved on the outer side of the threaded rod 12, and the outer end of the driving seat 14 slides on the inner side of the horizontal adjustment groove 9. A micro motor 13 is installed on the outer side of the fixing plate 11, and the output end of the micro motor 13 is connected to the input end of the threaded rod 12.

[0047] A passive protection component is arranged on the inner side of the liquid cooling housing 2, and the passive protection component includes a high thermal conductivity ceramic plate 3, a ceramic top frame 22 and a sealing gasket 23. The high thermal conductivity ceramic plate 3 is mounted on the top of the driving seat 14, the ceramic top frame 22 is mounted on the top of the high thermal conductivity ceramic plate 3, and the sealing gasket 23 is mounted on the opposite side of the ceramic top frame 22. An electronic device body 8 is mounted on the top of the liquid cooling seat 1, and the inner side of the high thermal conductivity ceramic plate 3 is in contact with the outer side of the electronic device body 8, and the ceramic top frame 22 is in contact with the top of the electronic device body 8;

[0048] The horizontal adjustment groove 9 provides a horizontal activity space for the driving seat 14. The gap between the high thermal conductivity ceramic plates 3 is adjusted according to the different specifications of the electronic device body 8. The fixing plate 11 provides an installation position for the micro motor 13 while ensuring its stability during operation. After the electronic device body 8 is installed on the liquid cooling seat 1, the micro motor 13 drives the threaded rod 12 to rotate. The driving seat 14 slides on the inner side of the horizontal adjustment groove 9 under the thread transmission of the threaded rod 12. The four groups of high thermal conductivity ceramic plates 3 are respectively in contact with the outer ends of the electronic device body 8 to achieve circumferential limit contact with the electronic device body 8. The two groups of ceramic top frames 22 are docked to protect the top thereof. The detachable sealing cover 4 is installed on the top of the liquid cooling shell 2, and the sealing gasket 23 realizes a good sealing docking of the ceramic top frame 22.

[0049] The passive protective layer formed by the high thermal conductivity ceramic plate 3 and the ceramic top frame 22 effectively isolates heat and prevents heat accumulation inside the device. When facing thermal runaway, the passive protective layer can quickly and effectively control the thermal runaway of the battery cell and hinder heat diffusion, preventing the coolant from directly contacting the sensitive components of the electronic device body 8, ensuring that the temperature distribution of various parts inside the electronic device is more uniform. The passive protective layer can effectively prevent coolant leakage. The design of immersion flame-retardant coolant combined with the passive protective layer can better ensure the safe operation of the electronic device body 8 under extreme conditions. Immersion cooling itself can provide excellent temperature uniformity performance, and the addition of a passive protective layer can further enhance this performance.

[0050] See also Figure 2 , Figure 4 , Figure 5 and Figure 6 , a liquid cooling device with high safety and a cooling method thereof;

[0051] It includes a temperature sensor 25, a flow path adjustment frame 5 and a baffle 29. A docking long groove 24 is opened on the outer side of a group of high thermal conductivity ceramic plates 3. The temperature sensor 25 is symmetrically installed on the inner wall of the liquid cooling shell 2. A heat transfer uniformity component is arranged on the inner side of the liquid cooling shell 2. The heat transfer uniformity component includes a flow path adjustment frame 5, a driving handle 28 and a baffle 29. The flow path adjustment frame 5 is symmetrically installed on the inner wall of the liquid cooling shell 2. The driving handle 28 is installed on the inner side of the flow path adjustment frame 5. The baffle 29 is installed at the telescopic end of the driving handle 28, and the baffle 29 slides on the inner wall of the flow path adjustment frame 5. A docking strip 30 is installed on the opposite side of the baffle 29, and the docking strip 30 matches the docking long groove 24.

[0052] The flow path adjustment frame 5 is symmetrically installed on the inner wall of the liquid cooling shell 2 and cooperates with the two groups of high thermal conductivity ceramic plates 3 symmetrically arranged in the front and rear. When the liquid cooling device is used normally, the coolant circulates, and the two groups of temperature sensors 25 respectively detect the temperature of the coolant flowing through the front and rear gaps between the electronic device body 8 and the liquid cooling shell 2. When the temperature sensor 25 detects that the heat conduction distribution inside the electronic device body 8 is uneven, that is, when the temperature value difference detected by the two groups of temperature sensors 25 is greater than the maximum value of the preset temperature value difference, the heat transfer uniformity component works, and the driving handle 28 works to push the baffle 29. The docking strip 30 is inserted into the inner side of the docking slot 24 to achieve a stable limit of the baffle 29, thereby ensuring the blocking stability of the baffle 29 on the coolant. The baffle 29 blocks the side with low temperature to change the flow path and flow rate of the coolant to achieve rapid cooling of the high thermal conductivity ceramic plate 3 on the side with high temperature by the coolant, and increase the coolant flow rate in the high heat load area of ​​the electronic device body 8 to achieve its uniform distribution on the high thermal conductivity ceramic plate 3.

[0053] See also Figure 1 , Figure 2 and Figure 7 , a liquid cooling device with high safety and a cooling method thereof;

[0054] It includes a cooling box 6, a reflux water pump 17 and a heat dissipation cooler 18. The cooling box 6 is installed on the outer side of the liquid cooling shell 2. A liquid supply port 20 is provided through the outer side of the liquid cooling shell 2, and the liquid supply port 20 is connected to the cooling box 6 through a pipeline. A reflux port 32 is provided through the outer side of the cooling box 6. A reflux water pump 17 is installed on the top of the liquid cooling seat 1.

[0055] The coolant enters through the liquid supply port 20 and is discharged from the liquid return port 21. When the liquid cooling device is in use, the working heat of the electronic device body 8 is quickly absorbed by the cooling liquid, and the reflux water pump 17 works to make the liquid flow and bring the heat to the cooling box 6. During the reflux of the coolant, the heat dissipation cooler 18 quickly cools the used coolant and transports it from the circulation pipe 19 through the reflux port 32 to the cooling box 6. After the coolant in the liquid-cooled shell 2 has been used for a long time, the control valve arranged on the front of the liquid-cooled shell 2 is opened to discharge the coolant for replacement. The coolant uses a synthetic fluorinated liquid.

[0056] See also Figure 1 , Figure 7 and Fig. 9 , a liquid cooling device with high safety and a cooling method thereof;

[0058] A liquid cooling processor 15 is installed on the front of the liquid cooling housing 2, and an alarm light 16 is installed on the front of the liquid cooling housing 2. The liquid cooling processor 15 consists of a cooling protection module and a signal receiving module. The cooling protection module is electrically connected to the micro motor 13, the heat transfer uniform component, the reflux water pump 17, the heat dissipation cooler 18, the cooling box 6 and the condenser 39. The signal receiving module is used to receive the output signals of the temperature sensor 25 and the liquid level sensor 26. The signal receiving module is electrically connected to the temperature difference comparison unit and the liquid level preset unit;

[0059] When the coolant flows back into the cooling box 6, the cooling pipe rack 35 cools the used coolant again. The water-based detergent and preservative are quantitatively added into the cooling box 6 through the water-based detergent storage tank 37 and the preservative storage tank 38 respectively. The water-based detergent and preservative are controlled by the automatic control valve to purify and treat the coolant. The water-based detergent can effectively remove oil, dust and other organic pollutants in the coolant, improve the cleanliness and transparency of the coolant, and the preservative is added to prevent the corrosion of water channel parts. The anticorrosive can form a protective film on the inner surface of the part to prevent the coolant from directly contacting with metal and other materials. Adding the anticorrosive can prevent the coolant from causing corrosion and damage to the parts inside the liquid cooling device. The mixed flow motor 33 drives the stirring rack 34 to rotate to fully mix the coolant, detergent and preservative in the cooling box 6. The purity detector 36 detects the concentration of the coolant. When the concentration is lower than the preset value, the coolant is replaced.

[0060] The liquid cooling processor 15 drives and controls the working status of the micro motor 13, the heat transfer uniformization component, the reflux water pump 17, the heat dissipation cooler 18, the cooling box 6 and the condenser 39 through the cooling protection module.

[0061] See also Figure 1 , Figure 4 and Figure 8 , a liquid cooling device with high safety and a cooling method thereof;

[0062] It includes a detachable sealing cover 4, an external seat 7 and a condenser 39. The external seat 7 is installed on the back of the liquid cooling shell 2, and the condenser 39 is installed on the top of the external seat 7. The output end of the condenser 39 is connected to the infusion tube 40. A drip port 31 is opened through the top of the cooling box 6, and the output end of the infusion tube 40 is connected to the drip port 31. An overpressure protection valve 41 is installed at the input end of the condenser 39, and the input end of the overpressure protection valve 41 is connected to the air supply pipe 42. The top of the liquid cooling shell 2 is installed with a detachable sealing cover 4, and a liquid level sensor 26 is installed on the inner wall of the liquid cooling shell 2. The top of the detachable sealing cover 4 is opened through the evaporation port 27, and the input end of the air supply pipe 42 is connected to the evaporation port 27.

[0063] The external seat 7 supports the condenser 39. When the temperature of the coolant is higher than the preset value, the reflux water pump 17 stops running, and the coolant in the liquid-cooled housing 2 continues to heat up. When the coolant is heated, it will evaporate in the evaporation space and absorb a large amount of heat to become gas. The evaporated gas enters the condenser 39 from the air supply pipe 42 through the evaporation port 27 and is re-liquefied, thereby realizing the recycling of the coolant vapor. The evaporative cooling technology effectively prevents the leakage of the liquid cooling layer. Since the evaporative cooling can keep the temperature inside the liquid-cooled housing 2 stable, it helps to reduce the failure of the electronic equipment body 8 caused by overheating. The overpressure protection valve 41 detects the steam pressure and automatically regulates it. The coolant cooled and liquefied by the condenser 39 falls from the infusion pipe 40 through the drip port 31 into the cooling box 6 for corresponding treatment. The liquid level sensor 26 detects the amount of coolant in the liquid-cooled housing 2. When the amount of coolant is lower than the preset value during the evaporative cooling process, the reflux water pump 17 works again to perform ordinary liquid cooling on the electronic equipment body 8 to prevent the electronic equipment body 8 from being immersed in the coolant due to insufficient coolant.

[0064] The cooling method of the liquid cooling device comprises the following steps:

[0065] Step S1, after the electronic device body 8 is installed on the liquid cooling seat 1, the micro motor 13 is operated to drive the threaded rod 12 to rotate, and the driving seat 14 slides inside the horizontal adjustment groove 9 under the thread transmission of the threaded rod 12, and the four groups of high thermal conductivity ceramic plates 3 are respectively in contact with the outer ends of the electronic device body 8;

[0066] Step S2, when the liquid cooling device is used, the working heat of the electronic device body 8 is quickly absorbed by the cooling liquid, the reflux water pump 17 works to make the liquid flow and bring the heat into the cooling box 6, when the temperature sensor 25 detects that the heat conduction distribution inside the electronic device body 8 is uneven, the heat transfer uniformity component works, and the baffle 29 blocks the side with low temperature to change the flow path and flow rate of the coolant to achieve the coolant to quickly cool the high thermal conductivity ceramic plate 3 on the side with high temperature;

[0067] Step S3, when the coolant flows back into the cooling box 6, the heat dissipation cooler 18 and the cooling pipe rack 35 cool the used coolant again, and the water-based detergent and preservative are used to purify and treat the coolant.

[0068] In step S1, the following steps are also included:

[0069] Step S11, two sets of ceramic top frames 22 are butted together to protect the tops thereof, and a detachable sealing cover 4 is installed on the top of the liquid cooling housing 2;

[0070] In step S2, the following steps are also included:

[0071] Step S21, when the coolant temperature is higher than the preset value, the reflux water pump 17 stops running, and the coolant in the liquid-cooled housing 2 continues to heat up. When the coolant is heated, it evaporates in the evaporation space and absorbs a large amount of heat. The evaporated gas enters the condenser 39 through the air supply pipe 42 and is reliquefied.

[0072] Working principle: When using the device, first install the electronic device body 8 above the liquid cooling seat 1, then the micro motor 13 runs to drive the threaded rod 12 to rotate, and the driving seat 14 slides inside the horizontal adjustment groove 9 under the thread transmission of the threaded rod 12, and the four groups of high thermal conductivity ceramic plates 3 are respectively in contact with the outer ends of the electronic device body 8, and the two groups of ceramic top frames 22 are connected to realize the protection of the top, and the detachable sealing cover 4 is installed on the top of the liquid cooling shell 2;

[0073] When the liquid cooling device is in use, the working heat of the electronic device body 8 is quickly absorbed by the cooling liquid, and the reflux water pump 17 works to make the liquid flow and bring the heat into the cooling box 6. When the temperature sensor 25 detects that the heat conduction distribution inside the electronic device body 8 is uneven, the heat transfer uniform component works, and the baffle plate 29 blocks the low-temperature side to change the flow path and flow rate of the coolant to achieve the coolant to quickly cool the high thermal conductivity ceramic plate 3 on the high-temperature side. When the coolant temperature is higher than the preset value, the reflux water pump 17 stops running, and the coolant in the liquid cooling housing 2 continues to heat up. When the coolant is heated, it evaporates in the evaporation space and absorbs a large amount of heat. The evaporated gas enters the condenser 39 through the air supply pipe 42 and re-liquefies.

[0074] When the coolant flows back into the cooling box 6, the heat dissipation cooler 18 and the cooling pipe rack 35 cool the used coolant again, and the water-based detergent and preservative purify and treat the coolant.
