Description

Technical Field

[0001] The present invention relates to the technical field of aircraft thermal management, and in particular to a heat pipe heat dissipation system and method based on temperature-sensitive hydrogel. Background Art

[0002] Aircraft electronic equipment is a key component of the aircraft. During the operation of the aircraft, the heat power consumption generated by the electronic equipment needs to be centrally processed by the onboard environmental control system. However, since the electronic equipment is distributed in various locations of the aircraft, it is difficult for the centralized cooling system to meet its heat dissipation needs. In order to establish distributed independent micro heat dissipation equipment, the use of heat pipes as heat transfer elements is currently a common solution. Heat pipes are an efficient heat transfer element that transfers heat by using the phase change processes of evaporation, condensation and reflux of the working medium. When one end of the heat pipe is heated, the liquid in the wick evaporates rapidly, and the generated steam flows to the other end under a small pressure difference. At the condensation end, the steam releases heat and condenses into liquid, and then the liquid flows back to the evaporation end along the porous material through capillary action. By integrating heat pipes near various electronic equipment of the aircraft during design, the heat generated by these devices can be collected and dissipated instantly and efficiently.

[0003] Under the flight conditions of the aircraft, the heat pipe will suffer from insufficient capillary force in the microchannels due to vibration and overload, thus causing heat transfer failure. Existing technical solutions mostly use micro water pumps to establish circulating heat dissipation channels, but micro water pumps require the construction of additional pipelines and power equipment, which is not conducive to the lightweight and miniaturization of heat dissipation equipment.

[0053] Electronic equipment on aircraft is often scattered in various locations on the aircraft, and centralized cooling systems are difficult to meet their cooling needs. Therefore, using heat pipes to establish independently distributed micro cooling devices is a common solution. However, when the aircraft is in flight, the heat pipes will have insufficient capillary force in the microchannels due to oscillation and overload, resulting in the inability of the working medium to circulate effectively in the heat pipes, which in turn causes heat transfer failure. For this reason, the existing technology mostly uses micro water pumps to establish circulation channels, but micro water pumps require additional power equipment and pipelines, which is not conducive to the lightweight cooling equipment.

[0054] In this embodiment, a heat pipe heat dissipation system based on temperature-sensitive hydrogel is provided. Figure 1 and Figure 2As shown, the heat pipe cooling system may include a cold plate component 04, a heating component 05, a heat exchange component 01, a flow guide component 02, and a hydrogel component 03. The heat exchange component 01 may exchange heat with the heating component 05, so that the heating component 05 may be cooled by the heat exchange component 01.

[0055] The flow guide assembly 02 may include a first flow guide unit 21 and a second flow guide unit 22. The first flow guide unit 21 may include a first flow guide pipe 213 and a second flow guide pipe 214, one end of the first flow guide pipe 213 is connected to the outlet of the cold plate assembly 04, and the other end is connected to the inlet of the heat exchange assembly 01. One end of the second flow guide pipe 214 is connected to the outlet of the heat exchange assembly 01, and the other end is connected to the inlet of the cold plate assembly 04. Thus, the cooling medium can be circulated and dissipated from the heat exchange assembly 01 to the cold plate assembly 04 and then to the heat exchange assembly 01 through the first flow guide pipe 213 and the second flow guide pipe 214. The second flow guide unit 22 may include a third flow guide pipe 222 and a fourth flow guide pipe 223.

[0056] like Figure 3 As shown, the hydrogel assembly 03 includes a first storage unit 31 and a hydrogel unit 33. The hydrogel unit 33 is disposed in the first storage unit 31. The first storage unit 31 can exchange heat with the heat exchange assembly 01, so that the hydrogel unit 33 disposed in the first storage unit 31 can shrink and discharge the cooling medium when the temperature rises based on the temperature-sensitive characteristics. Figure 3 As shown, the first storage unit 31 can be connected to the cold plate assembly 04 through the third flow guide pipe 222; Figure 4 As shown, the first storage unit 31 can be connected to the heat exchange component 01 through the fourth flow conduit 223. Then, the excess cooling medium condensed near the cold plate component 04 can be absorbed by the hydrogel component 03 through the third flow conduit 222, and the cooling medium discharged by the hydrogel component 03 due to heat can flow into the heat exchange component 01 through the fourth flow conduit 223. Among them, the hydrogel unit 33 is composed of negative temperature sensitive hydrogel, and the volume can shrink as the temperature rises. Poly (N-isopropyl acrylamide) (PNIPAM), poly (N-n-propyl acrylamide) (PNNPAM), poly (N, N-diethyl acrylamide) (PDEAM), polypropylene glycol (PPO), polyethylene glycol, etc. can be used.

[0057] The heat pipe cooling system also includes a first state. The first state includes the hydrogel unit 33 discharging cooling medium, and the cooling medium flows into the heat exchange component 01 through the fourth guide pipe 223, which can replenish the cooling medium evaporated in the heat pipe, thereby avoiding the situation of insufficient capillary force and achieving smooth circulation and heat dissipation. In addition, the weight of the hydrogel unit 33 is light without the cooling medium, and there is no need to add additional power equipment or pipelines, which can achieve lightweight cooling system.

[0058] In this embodiment, if Figure 4 and Fig.10 As shown, the heat exchange assembly 01 may include a heat exchange plate 11, a first heat exchange tube 12, a second heat exchange tube 13, and a third heat exchange tube 14. The heat exchange plate 11 is attached to one side of the heat exchange assembly 05, and the heat exchange plate 11 can completely cover the heat exchange assembly 05 to maximize the heat exchange area with the heat exchange assembly 05 and improve the heat exchange efficiency. The first heat exchange tube 12, the second heat exchange tube 13, and the third heat exchange tube 14 can be arranged inside the heat exchange plate 11. One end of the first heat exchange tube 12 can be connected to the fourth guide tube 223, and the other end can be connected to the second heat exchange tube 13, so that the cooling medium cooled by the cold plate assembly 04 can flow into the first heat exchange tube 12 through the fourth guide tube 223, and then flow into the second heat exchange tube 13. The first heat exchange tube 12 penetrates the heat exchange plate 11 along the first direction, and the first heat exchange tube 12 is arranged in the heat exchange plate 11 at intervals along the second direction. The first direction is perpendicular to the second direction. The second heat exchange tube 13 extends in the heat exchange plate 11 along the second direction and is connected to the third heat exchange tube 14. The second heat exchange tube 13 can be arranged adjacent to the inlet end of the third heat exchange tube 14, which is also the inlet end of the heat exchange assembly 01.

[0059] The third heat exchange tube 14 can penetrate the heat exchange plate 11 along the first direction. The third heat exchange tube 14 is arranged adjacent to the side of the heat exchange plate 11 close to the heating component 05. A plurality of third heat exchange tubes 14 are arranged in the interval area between the two first heat exchange tubes 12 along the second direction, thereby increasing the heat exchange area with the heating component 05 and improving the heat exchange efficiency. The inlet end of the third heat exchange tube 14 is connected to the first flow guide tube 213, and the outlet end of the third heat exchange tube 14 is connected to the second flow guide tube 214. Therefore, the cooling circulation loop composed of the cold plate component 04, the first flow guide tube 213, the third heat exchange tube 14, and the second flow guide tube 214 can be called the first loop. When the temperature of the heating component 05 is too high and the cooling medium in the third heat exchange tube 14 evaporates too quickly, resulting in insufficient capillary force, the first storage unit 31 exchanges heat with the heat exchange component 01, and the hydrogel component 03 is heated and discharges the cooling medium. The cooling medium can flow into the fourth guide tube 223, the first heat exchange tube 12, the second heat exchange tube 13, and finally into the third heat exchange tube 14 to enter the first circuit and participate in the cooling cycle. Among them, the second heat exchange tube 13 is connected to the inlet end of the third heat exchange tube 14, so that the cooling medium can flow completely through the side of the heat exchange plate 11 that is attached to the heating component 05, that is, completely flow through the third heat exchange tube 14 that exchanges the most heat with the heating component 05, so that the cooling medium in the first circuit is fully replenished, avoiding partial evaporation of the cooling medium and the circuit with insufficient capillary force from being replenished. The cooling medium in the first heat exchange tube 12, the second heat exchange tube 13, and the third heat exchange tube 14 all exchange heat with the heating component 05.

[0060] The heat pipe cooling system also includes a second state and a third state. The second state includes the cooling medium flowing through the cold plate assembly 04 and the third guide tube 222 to the first storage unit 31 in sequence, and the hydrogel unit 33 absorbs excess cooling medium. The third state includes a cooling circulation loop formed by the cooling medium flowing through the cold plate assembly 04, the first guide tube 213, the third heat exchange tube 14, and the second guide tube 214, that is, the first loop. The first state and the second state can exist simultaneously with the third state. On the basis of the first loop of the third state, the hydrogel assembly 03 can absorb excess cooling medium, or discharge cooling medium to supplement the first loop.

[0061] In this embodiment, if Figure 2 As shown, the first guide unit 21 further includes a first guide plate 211 and a second guide plate 212. The first guide plate 211 and the second guide plate 212 are arranged at intervals on both sides of the heat exchange plate 11 along the first direction. Figure 5 , Figure 6 , Fig. 9 As shown, the first flow guide tube 213 penetrates the first flow guide plate 211, and the second flow guide tube 214 penetrates the second flow guide plate 212. Multiple first flow guide tubes 213 are arranged in the first flow guide plate 211 at intervals, and the outlets of the multiple first flow guide tubes 213 are connected to the inlets of the multiple third heat exchange tubes 14 in a one-to-one correspondence. Multiple second flow guide tubes 214 are arranged in the second flow guide plate 212 at intervals, and the inlets of the multiple second flow guide tubes 214 are connected to the outlets of the multiple third heat exchange tubes 14 in a one-to-one correspondence. The circulation loop formed by the multiple first flow guide tubes 213, the multiple second flow guide tubes 214 and the multiple third heat exchange tubes 14 can ensure that the flow rate of the cooling medium meets the heat dissipation requirements.

[0062] In this embodiment, if Figure 3 , Figure 4 As shown, the first storage unit 31 includes a first hydrogel plate 311, a first hydrogel chamber 312, a first channel 313 and a second channel 314. The first hydrogel chamber 312 is connected to the first channel 313 and the second channel 314 respectively, and a plurality of first hydrogel chambers 312 are arranged in intervals between the first channel 313 and the second channel 314. The hydrogel unit 33 can be arranged in the first hydrogel chamber 312, such as Fig.13As shown, the first channel 313 and the second channel 314 can be connected to the upper end and the lower end of the first hydrogel chamber 312, respectively. The first hydrogel plate 311 is spaced or fitted with the side of the heat exchange plate 11 away from the heat generating assembly 05, and heat can be exchanged between the first hydrogel plate 311 and the heat exchange plate 11. The first channel 313 penetrates the first hydrogel plate 311 along the second direction, and the second channel 314 penetrates the first hydrogel plate 311 along the second direction. The first channel 313 is connected to the outlet of the third flow guide 222, and the second channel 314 is connected to the inlet of the fourth flow guide 223. The first channel 313 is arranged adjacent to the side of the first hydrogel plate 311 close to the cold plate assembly 04, and the excess cooling medium condensed in the cold plate assembly 04 can flow into the first hydrogel chamber 312 through the third flow guide 222 and the first channel 313 and be absorbed by the hydrogel unit 33. The second channel 314 is arranged adjacent to the first hydrogel plate 311 and close to the side of the heat exchange component 01. The hydrogel unit 33 in the first hydrogel chamber 312 can sense the temperature contraction of the heat exchange component 01, and the discharged cooling medium can flow into the heat exchange component 01 through the second channel 314 and the fourth flow guide pipe 223 more quickly and replenish the cooling medium in the third heat exchange tube 14. Multiple first channels 313 are arranged at intervals along the first direction, and multiple second channels 314 are arranged at intervals along the first direction, which can ensure that the compensation amount of the cooling medium meets the requirements of the cooling cycle.

Figure 8 As shown, the third guide tube 222 penetrates the third guide plate 221, and the fourth guide tube 223 penetrates the third guide plate 221. A plurality of third guide tubes 222 and a plurality of fourth guide tubes 223 are alternately arranged in the third guide plate 221. Figure 3 As shown, the outlets of the plurality of third flow guide pipes 222 are connected to the inlets of the plurality of first channels 313 in a one-to-one correspondence. Figure 4As shown, the inlets of the plurality of fourth flow guide tubes 223 are connected one by one with the outlets of the plurality of second channels 314. Thus, the third flow guide tubes 222 and the fourth flow guide tubes 223 are present on both sides of the heat exchange plate 11, i.e., both sides of the hydrogel assembly 03, and the cooling medium in the hydrogel units 33 distributed on both sides can be compensated to the heat exchange assembly 01 through the second channels 314 and the fourth flow guide tubes 223 at a faster speed, while the excess cooling medium in the cold plate assembly 04 can also flow into the hydrogel unit 33 through the third flow guide tubes 222 and the first channels 313 at a faster speed, thereby improving the circulation efficiency of the cooling medium in the heat dissipation system.

[0065] In this embodiment, if Figure 3 As shown, the projection of the first hydrogel plate 311 on the heat exchange plate 11 completely covers the heat exchange plate 11 , so that the first hydrogel plate 311 can better sense the temperature of the heat exchange plate 11 and switch to the corresponding first state or second state.

[0066] like Fig.11 As shown, the hydrogel unit 33 may include a first hydrogel 331, a second hydrogel 332, and a third hydrogel 333. The first hydrogel 331, the second hydrogel 332, and the third hydrogel 333 may be sequentially arranged in the first direction and distributed in the first hydrogel chamber 312. The direction in which the first hydrogel 331, the second hydrogel 332, and the third hydrogel 333 are sequentially arranged may be the same direction in which the cooling medium flows along the third heat exchange tube 14. There may be multiple first hydrogels 331, second hydrogels 332, and third hydrogels 333.

[0067] A>B>C. Wherein, A is the reaction temperature of the first hydrogel 331, B is the reaction temperature of the second hydrogel 332, and C is the reaction temperature of the third hydrogel 333. The second heat exchange tube 13 is close to the inlet end of the third heat exchange tube 14, and the distances between the first hydrogel 331, the second hydrogel 332 and the third hydrogel 333 and the second heat exchange tube 13 gradually increase, so the cooling medium discharged from the third hydrogel 333 takes a longer time to flow into the third heat exchange tube 14. In order to avoid the cooling medium discharged from the third hydrogel 333 failing to be replenished to the third heat exchange tube 14 in time after the cooling medium of the first hydrogel 331 is exhausted, the reaction temperature of the third hydrogel 333 is set to be relatively low, so that the cooling medium can be discharged before the first hydrogel 331, so as to give priority to the use of the hydrogel component 03 which is farther away, and the reaction temperatures of the first hydrogel 331 and the second hydrogel 332 which are closer and can be replenished quickly are set to be higher, so as to quickly replenish the cooling medium for the third heat exchange tube 14 when the third hydrogel 333 is insufficient in water.

[0068] In this embodiment, if Figure 3 and Figure 4As shown, the hydrogel assembly 03 also includes a second storage unit 32. The second storage unit 32 may include a second hydrogel plate 321, a second hydrogel chamber 322, a third channel 323, and a fourth channel 324. The second hydrogel chamber 322 is communicated with the third channel 323 and the fourth channel 324, respectively, and a plurality of second hydrogel chambers 322 are arranged at intervals in the interval area between the third channel 323 and the fourth channel 324. The hydrogel unit 33 may be arranged in the second hydrogel chamber 322, and the third channel 323 and the fourth channel 324 may be communicated with the upper end and the lower end of the second hydrogel chamber 322, respectively. One side of the second hydrogel plate 321 is closely attached to the side of the first hydrogel plate 311 close to the cold plate assembly 04, and the second hydrogel plate 321 may exchange heat with the first hydrogel plate 311.

[0069] The third channel 323 penetrates the second hydrogel plate 321 along the second direction, and the fourth channel 324 penetrates the second hydrogel plate 321 along the second direction. The third channel 323 is connected to the outlet of the third flow guide tube 222, and the fourth channel 324 is connected to the inlet of the fourth flow guide tube 223. The third channel 323 is arranged adjacent to the side of the second hydrogel plate 321 close to the cold plate assembly 04, and the excess cooling medium condensed in the cold plate assembly 04 can flow into the second hydrogel cavity 322 through the third flow guide tube 222 and the third channel 323 and be absorbed by the hydrogel unit 33. The fourth channel 324 is arranged adjacent to the side of the second hydrogel plate 321 close to the heat exchange assembly 01, and the hydrogel unit 33 in the second hydrogel cavity 322 can sense the temperature of the first storage unit 31 and shrink, and the discharged cooling medium can flow into the heat exchange assembly 01 through the fourth channel 324 and the fourth flow guide tube 223 and replenish the cooling medium in the third heat exchange tube 14. The plurality of third channels 323 are arranged at intervals along the first direction, and the plurality of fourth channels 324 are arranged at intervals along the first direction, which can further ensure that the compensation amount of the cooling medium meets the requirements of the cooling cycle.

[0070] The first state also includes the cooling medium flowing into the fourth guide pipe 223 through the fourth channel 324 ; the second state also includes the cooling medium flowing into each second hydrocondensation chamber 322 through the third channel 323 .

[0071] In another embodiment, the hydrogel assembly 03 may further include a third storage unit, which may include a third hydrogel plate, a third hydrogel chamber, a fifth channel, and a sixth channel. One side of the third hydrogel plate may be closely fitted with the side of the second hydrogel plate 321 close to the cold plate assembly 04. The fifth channel may be connected to the outlet of the third flow guide 222 so that the hydrogel unit 33 in the third hydrogel chamber absorbs excess cooling medium, and the sixth channel may be connected to the inlet of the fourth flow guide 223 so that the hydrogel unit 33 in the third hydrogel chamber senses temperature and discharges cooling medium to replenish the third heat exchange tube 14. It can be inferred that the hydrogel assembly 03 may further include a fourth storage unit, a fifth storage unit, etc., so as to ensure that the cooling medium in the third heat exchange tube 14 is sufficient.

[0072] In this embodiment, the hydrogel unit 33 may further include a fourth hydrogel, a fifth hydrogel, and a sixth hydrogel. The fourth hydrogel, the fifth hydrogel, and the sixth hydrogel may be sequentially arranged in the first direction and distributed in the second hydrogel chamber 322. The direction in which the fourth hydrogel, the fifth hydrogel, and the sixth hydrogel are sequentially arranged may be the same direction in which the cooling medium flows along the third heat exchange tube 14. There may be multiple fourth hydrogels, fifth hydrogels, and sixth hydrogels.

[0073] E>F>G; E<A, F<B, G<C. Wherein, E is the reaction temperature of the fourth hydrogel, F is the reaction temperature of the fifth hydrogel, and G is the reaction temperature of the sixth hydrogel.

[0074] The second heat exchange tube 13 is close to the inlet end of the third heat exchange tube 14, and the distances between the fourth hydrogel, the fifth hydrogel and the sixth hydrogel and the second heat exchange tube 13 gradually increase, so the cooling medium discharged from the sixth hydrogel takes a longer time to flow into the third heat exchange tube 14. In order to avoid the cooling medium discharged from the sixth hydrogel failing to be replenished to the third heat exchange tube 14 in time after the cooling medium of the fourth hydrogel is discharged, the reaction temperature of the sixth hydrogel is set to be relatively low, so that the cooling medium can be discharged before the fourth hydrogel, and the hydrogel component 03 with a longer distance is preferentially used, while the reaction temperatures of the fourth hydrogel and the fifth hydrogel, which are closer and can be replenished quickly, are set to be higher, so that the cooling medium can be quickly replenished to the third heat exchange tube 14 when the sixth hydrogel is insufficient in water.

[0075] In addition, the distance between the second hydrogel chamber 322 and the heat exchange component 01 is greater than the distance between the first hydrogel chamber 312 and the heat exchange component 01. Therefore, the temperature in the second hydrogel chamber 322 is lower. The reaction temperature of the hydrogel unit 33 in the second hydrogel chamber 322 can be set lower than that of the hydrogel unit 33 in the first hydrogel chamber 312. The second hydrogel 332, which is farther away from the third heat exchange tube 14, is preferentially used. At the same time, it also avoids the hydrogel unit 33 in the second hydrogel chamber 322 from being unable to reach the reaction temperature for a long time, so that the hydrogel unit 33 in the second hydrogel chamber 322 can replenish the cooling medium for the cooling circulation loop more quickly.

[0076] In this embodiment, if Fig.12 As shown, the first hydrogel 331 can be divided into a first glue part 3311, a second glue part 3312, and a third glue part 3313 in sequence along the second direction. A1>A2, A1=A3. Wherein, A1 is the reaction temperature of the first glue part 3311, A2 is the reaction temperature of the second glue part 3312, and A3 is the reaction temperature of the third glue part 3313. In the cooling medium flowing into the third heat exchange tube 14 through the fourth flow guide 223, the cooling medium temperature in the third heat exchange tube 14 located on both sides close to the fourth flow guide 223 is low, and the cooling medium temperature in the third heat exchange tube 14 located in the middle is high. In order to ensure that parts with different temperatures can have sufficient cooling medium, the reaction temperature of the first hydrogel 331, i.e., the first glue part 3311 and the third glue part 3313, close to both ends of the fourth flow guide 223 can be high, and the reaction temperature A2 of the third glue part 3313 in the middle can be low, so that the cooling medium is discharged in time for replenishment.

[0077] The second hydrogel 332 is divided into a fourth gel part 3321, a fifth gel part 3322, and a sixth gel part 3323 along the second direction. B1>B2, B1=B3; A1>B1, A2>B2. Among them, B1 is the reaction temperature of the fourth gel part 3321, B2 is the reaction temperature of the fifth gel part 3322, and B3 is the reaction temperature of the sixth gel part 3323. In order to ensure that parts with different temperatures can have sufficient cooling medium, the reaction temperature of the second hydrogel 332 near the two ends of the fourth guide tube 223, i.e., the fourth gel part 3321 and the sixth gel part 3323, can be higher, and the reaction temperature B2 of the fifth gel part 3322 in the middle can be lower, so that the cooling medium can be discharged in time for replenishment.

[0078] The third hydrogel 333 is divided into a seventh gel part 3331, an eighth gel part 3332, and a ninth gel part 3333 in the second direction. C1>C2, C1=C3; B1≥C1, B2≥C2. Among them, C1 is the reaction temperature of the seventh gel part 3331, C2 is the reaction temperature of the eighth gel part 3332, and C3 is the reaction temperature of the ninth gel part 3333. In order to ensure that parts with different temperatures can have sufficient cooling medium, the reaction temperature of the third hydrogel 333, i.e., the seventh gel part 3331 and the ninth gel part 3333, near the two ends of the fourth guide tube 223 can be higher, and the reaction temperature C2 of the eighth gel part 3332 in the middle can be lower, so that the cooling medium can be discharged in time for replenishment.

[0079] In another embodiment, the fourth hydrogel can be divided into a tenth gel part, an eleventh gel part, and a twelfth gel part in sequence along the second direction. E1>E2, E1=E3. Wherein, E1 is the reaction temperature of the tenth gel part, E2 is the reaction temperature of the eleventh gel part, and E3 is the reaction temperature of the twelfth gel part.

[0080] The fifth hydrogel can be divided into a thirteenth gel part, a fourteenth gel part, and a fifteenth gel part in sequence along the second direction. F1>F2, F1=F3; E1>F1, E2>F2. Wherein, F1 is the reaction temperature of the thirteenth gel part, F2 is the reaction temperature of the fourteenth gel part, and F3 is the reaction temperature of the fifteenth gel part.

[0081] The sixth hydrogel is divided into the sixteenth gel part, the seventeenth gel part, and the eighteenth gel part in sequence along the second direction. G1>G2, G1=G3; F1≥G1, F2≥G2. Wherein, G1 is the reaction temperature of the sixteenth gel part, G2 is the reaction temperature of the seventeenth gel part, and G3 is the reaction temperature of the eighteenth gel part.

[0082] In this embodiment, the heat exchange assembly 01 may also include a fourth heat exchange tube. The fourth heat exchange tube extends in the heat exchange plate 11 along the second direction. One end of the fourth heat exchange tube can be connected to the first heat exchange tube 12, and the other end can be connected to the third heat exchange tube 14, so that the cooling medium discharged from the hydrogel unit 33 can flow into the third heat exchange tube 14 through the fourth guide tube 223, the first heat exchange tube 12, and the fourth heat exchange tube, and enter the cooling cycle. The fourth heat exchange tube can be arranged in the middle area of ​​the heat exchange plate 11 along the first direction, so that the cooling medium can be quickly replenished to the part with a temperature higher than the inlet of the third heat exchange tube 14 to avoid heat transfer failure.

[0083] In another embodiment, a plurality of fourth heat exchange tubes may be provided, and the plurality of fourth heat exchange tubes may correspond one to one with the plurality of fourth flow guide tubes 223, so that the hydrogel components 03 in each area can more flexibly sense the temperature transmitted by the heat exchange component 01, and thus accurately and quickly replenish the cooling medium for the third heat exchange tube 14.

[0084] In this embodiment, a heat pipe heat dissipation method based on a temperature-sensitive hydrogel is provided. The heat pipe heat dissipation method includes steps S10 to S40. Each step is described in detail as follows:

[0085] Step S10, based on the heat exchange between the heating component 05 and the heat exchange component 01, the temperature of the heating component 05 is obtained.

[0086] Step S20, based on the temperature of the heating component 05 being within the first temperature range, the heat pipe cooling system operates in the first state. The first state includes the hydrogel unit 33 discharging the cooling medium, and the cooling medium flows into the heat exchange component 01 through the fourth flow guide tube 223. At this time, the temperature of the heating component 05 is relatively high, the cooling medium in the heat pipe evaporates more, the capillary force is insufficient, and the cooling efficiency is extremely low. The heat pipe cooling system operates at high power, the hydrogel unit 33 discharges the cooling medium and flows through the fourth flow guide tube 223 to replenish the heat exchange component 01, so that the cooling cycle can operate normally.

[0087] Step S30, based on the temperature of the heating component 05 being in the second temperature range, the heat pipe cooling system operates in the second state. The second state includes the cooling medium flowing through the cold plate component 04 and the third flow conduit 222 to the first storage unit 31 in sequence, and the hydrogel unit 33 absorbs the cooling medium. At this time, the cooling medium in the heat pipe condenses more in the cold plate component 04, and the excess cooling medium flows through the third flow conduit 222 and is absorbed by the hydrogel unit 33.

[0088] Step S40, based on the temperature of the heating component 05 being within the third temperature range, the heat pipe cooling system operates in the third state. The third state includes a circulation loop formed by the cooling medium flowing through the cold plate component 04, the first guide tube 213, the heat exchange component 01, and the second guide tube 214. At this time, the temperature of the heating component 05 is moderate, the hydrogel unit 33 maintains a stable state, and the cooling medium circulates stably in the cooling loop in the third state, which is sufficient to achieve heat dissipation of the heating component 05.

[0089] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present disclosure, and in actual applications, various changes may be made thereto in form and detail without departing from the scope of the present disclosure.
