Description

Technical Field

[0001] This invention belongs to the field of dedicated safety facilities for floating nuclear power platforms, and specifically relates to an evaporation device and a heat exchange system. Background Technology

[0002] A high-efficiency heat exchange system is used to transfer heat from one place to another. A high-efficiency heat transfer device consists of a sealed metal pipe system filled with a working medium. Heat exchange transfer devices are typically divided into three parts: an evaporation section, a condensation section, and a liquid loop section. The evaporation section is located near the heat source. When the heat source heats the split heat pipe, the working medium is heated and evaporates into steam within the evaporator. The steam rises in the heat pipe, carrying away heat, and then enters the condenser. The condensation section is located where heat needs to be transferred. The external environment temperature of the condensation section is lower, and the steam cools and reverts to liquid within the condensation section. In this way, heat is released into the environment surrounding the condensation section. In the liquid loop section, the liquid medium spontaneously returns from the condenser to the evaporation section, forming a cycle. This cycle continuously transfers heat from the heat source to the point of need. Heat exchange systems are characterized by high efficiency, reliability, and energy saving. They can rapidly transfer heat between the heat source and the radiator, effectively solving problems of heat concentration and insufficient heat dissipation. Split heat pipes are widely used in electronic equipment heat dissipation, solar water heaters, air conditioning systems, and other fields.

[0003] The evaporation device used in the evaporation section of the heat exchange system includes a liquid storage chamber, an evaporation chamber, and a heat absorption tube. The liquid storage chamber is connected to the liquid outlet of the condenser, and the evaporation chamber is connected to the gas inlet of the condenser. The heat absorption tube draws the liquid medium from the liquid storage chamber into the heat absorption tube for evaporation through capillary force and pressure difference. However, traditional heat absorption tubes may not evaporate completely, resulting in the simultaneous presence of liquid medium and vapor in the heat absorption tube. The liquid will evaporate again after entering the evaporation chamber. If there is a large amount of liquid medium, it cannot be completely evaporated in the evaporation chamber and will instead accumulate in the evaporation chamber, causing blockage of the outlet of the heat absorption tube. This prevents the vapor from being discharged from the heat absorption tube, affecting the evaporation efficiency of the liquid medium. Moreover, existing evaporation devices also cause heat loss when transmitting vapor over long distances. Summary of the Invention

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0024] A high-efficiency heat exchange system is used to transfer heat from one place to another. A high-efficiency heat transfer device consists of a sealed metal pipe system filled with a working medium. Heat exchange transfer devices are typically divided into three parts: an evaporation section, a condensation section, and a liquid loop section. The evaporation section is located near the heat source. When the heat source heats the split heat pipe, the working medium is heated and evaporates into steam within the evaporator. The steam rises in the heat pipe, carrying away heat, and then enters the condenser. The condensation section is located where heat needs to be transferred. The external environment temperature of the condensation section is lower, and the steam cools and reverts to liquid within the condensation section. In this way, heat is released into the environment surrounding the condensation section. In the liquid loop section, the liquid medium spontaneously returns from the condenser to the evaporation section, forming a cycle. This cycle continuously transfers heat from the heat source to the point of need. Heat exchange systems are characterized by high efficiency, reliability, and energy saving. They can rapidly transfer heat between the heat source and the radiator, effectively solving problems of heat concentration and insufficient heat dissipation. Split heat pipes are widely used in electronic equipment heat dissipation, solar water heaters, air conditioning systems, and other fields.

[0025] The evaporation device used in the evaporation section of the heat exchange system includes a liquid storage chamber c, an evaporation chamber, and a heat absorption tube. The liquid storage chamber c is connected to the liquid outlet of the condenser, and the evaporation chamber is connected to the gas inlet of the condenser. The heat absorption tube draws the liquid medium from the liquid storage chamber c into the heat absorption tube for evaporation through capillary force and pressure difference. However, traditional heat absorption tubes may not evaporate completely, resulting in the simultaneous presence of liquid medium and vapor in the heat absorption tube. The liquid will evaporate again after entering the evaporation chamber. If there is a large amount of liquid medium, it cannot be completely evaporated in the evaporation chamber and will instead accumulate in the evaporation chamber, causing blockage of the outlet of the heat absorption tube. This prevents the vapor from being discharged from the heat absorption tube, affecting the evaporation efficiency of the liquid medium. Moreover, existing evaporation devices also cause heat loss when transmitting vapor over long distances.

[0026] This invention provides an evaporation device with high evaporation efficiency and minimal heat loss during long-distance steam transfer.

[0027] This application provides an evaporation device, comprising: an evaporation body 1 with an internal accommodating space; a first partition plate 11 disposed inside the evaporation body 1; a second partition plate 12 disposed inside the evaporation body 1 at a preset distance from the first partition plate 11, the first partition plate 11 and the second partition plate 12 dividing the evaporation body 1 into an evaporation chamber a, a heat absorption chamber b, and a liquid storage chamber c; a gas pipe 2 connected to the evaporation chamber a; a liquid pipe 3 with multiple liquid inlet pipes 31, the walls of which are provided with liquid inlet holes 311; a heat absorption tube assembly 4 disposed in the heat absorption chamber b, the heat absorption tube assembly 4 being connected to the evaporation chamber a and the liquid storage chamber c respectively; and a liquid control mechanism 5 including a water absorption plate 51 and multiple sealing components, the water absorption plate 51 being disposed in the evaporation chamber a, one end of each sealing component being connected to the water absorption plate 51, and the other end of each sealing component being able to extend into the interior of the liquid inlet pipe 31, the number of sealing components being at least one less than the number of liquid inlets.

[0028] Specifically, the evaporation device includes an evaporation chamber a, a heat absorption chamber b, a liquid storage chamber c, and a heat absorption tube assembly 4. The two ends of the heat absorption tube assembly 4 are connected to the evaporation chamber a and the liquid storage chamber c, respectively. The liquid storage chamber c is also connected to a liquid pipe 3, and the evaporation chamber a is also connected to a gas pipe 2. When the split heat pipe is used, the gas pipe 2 is connected to the gas inlet of the condensing device 6, and the liquid pipe 3 is connected to the liquid outlet of the condensing device 6. In this way, the liquid medium evaporates and absorbs heat to become steam under the action of the evaporation device. After entering the condensing device 6 through the gas pipe 2, it releases heat and liquefies back into the liquid medium and then flows back to the liquid storage chamber c through the liquid pipe 3. As the liquid volume in the liquid storage chamber c increases, the liquid will be drawn into the heat absorption tube assembly 4 and the evaporation chamber a for evaporation again. In the continuous cycle, the heat of the evaporation device is transferred to the condensing device 6, realizing the effect of heat exchange.

[0029] Furthermore, when the liquid medium in the evaporation chamber a cannot evaporate in time, the sealing component blocks the liquid inlet hole 311 of the liquid inlet pipe 31, thereby controlling the flow rate of the liquid inlet pipe 31 and reducing the amount of liquid entering the liquid storage chamber c. This prevents the liquid medium from accumulating too much in the evaporation chamber a and affecting the steam discharge in the heat absorption tube assembly 4, effectively improving the evaporation efficiency of the liquid medium. In addition, the liquid control mechanism 5 uses the water absorption plate 51 to absorb the liquid medium that cannot evaporate in time, preventing the blockage of the inlet of the heat absorption tube assembly 4. The water absorption plate 51, due to its own weight after absorbing liquid, presses down on the sealing element 52, blocking part of the liquid inlet pipe 31, thereby reducing the liquid flow rate and improving the evaporation efficiency of the liquid medium.

[0030] Optionally, the liquid control mechanism 5 includes a water-absorbing plate 51, a sealing element 52, and a connecting rod 53. The connecting rod 53 connects the sealing element 52 and the water-absorbing plate 51, respectively. The sealing element 52 is a sealing block. The water-absorbing plate 51 is installed inside the evaporation chamber a, and the sealing block is installed inside the liquid inlet pipe 31 located in the liquid storage chamber c. The liquid inlet pipe 31 is connected to the liquid pipe 3. The water-absorbing plate 51 and the sealing block are connected by the connecting rod 53. An isolation cylinder 13 is provided between the evaporation chambers a. The gap between the isolation cylinder 13 and the inner surface of the evaporation body 1 corresponds to the liquid inlet pipe 31. The gap between the isolation cylinder 13 and the inner surface of the evaporation body 1 allows the connecting rod 53 to pass through. The liquid inlet pipe 31 has a liquid inlet hole 311, which is used to push the sealing block to seal the liquid inlet hole 311 after the water-absorbing plate 51 absorbs liquid, increasing its weight. After the liquid evaporates in the absorbent plate 51, its weight reduces the buoyancy of the inlet pipe 31, pushing the sealing block away from the inlet hole 311. As mentioned above, the evaporation device uses the heat-absorbing tube assembly 4 for evaporation and liquid absorption. Although the entire evaporation device is immersed in the heat source, the heat-absorbing tube assembly 4 cannot guarantee complete evaporation of the liquid medium. Therefore, the liquid medium in the heat-absorbing tube assembly 4 will also flow into the evaporation chamber a for further evaporation. If there is too much liquid accumulation, a large amount of liquid medium will continue to enter the storage chamber c, which can easily cause the liquid medium to fill the evaporation chamber a, affecting the entry of steam into the gas pipe 2 and reducing the efficiency of steam generation. However, by using the liquid control mechanism 5, when liquid accumulates in the evaporation chamber a, the flow rate of liquid flowing from the inlet pipe 31 to the storage chamber c can be controlled and reduced, thereby providing sufficient space for steam discharge in the evaporation chamber a and the heat-absorbing tube assembly 4, indirectly improving the evaporation efficiency.

[0031] The liquid control mechanism 5 mainly reduces the amount of liquid entering by blocking the liquid inlet 311 with a sealing block. The sealing block is linked to the water absorption plate 51 by the connecting rod 53. Initially, the sealing block is above the liquid inlet 311, and the water absorption plate 51 is located inside the evaporation chamber a. The water absorption plate 51 has the characteristic of absorbing liquid. When there is unevaporated liquid medium in the evaporation chamber a, it will be absorbed by the water absorption plate 51, reducing the amount of liquid medium in the evaporation chamber a. After absorbing liquid, the weight of the water absorption plate 51 increases, which will cause the sealing block to move down through the connecting rod 53. The sealing block moves to the position of the liquid inlet 311 and blocks the liquid inlet 311. At this time, no liquid flows out of the liquid inlet pipe 31. In this way, the liquid medium in the liquid storage chamber c cannot be replenished, and the evaporation chamber a can evaporate the liquid medium in the water absorption plate 51 and the heat absorption tube 41, thereby improving the evaporation efficiency.

[0032] The above describes how the liquid control mechanism 5 improves evaporation efficiency, but only one working state is described. To ensure the automated operation of the liquid control mechanism 5, the following design is required: The bottom end of the liquid inlet pipe 31 is connected to the liquid pipe 3, the connecting rod 53 is connected to the sealing block, the liquid inlet hole 311 is opened on the side wall of the liquid inlet pipe 31, the sealing block is piston-type connected to the inner wall of the liquid inlet pipe 31, and the liquid inlet hole 311 is within the movement range of the sealing block. The connection between the sealing block and the liquid inlet pipe 31 is piston-type. When the weight of the suction plate 51 is greater than the thrust of the liquid outlet of the liquid inlet pipe 31, the sealing block moves down to block the liquid inlet hole 311, cutting off the replenishment of the liquid medium. After the liquid medium has fully evaporated, the weight of the suction plate 51 is reduced to less than the thrust of the liquid outlet of the liquid inlet hole 311, and the sealing block is pushed upward by the liquid to expose the liquid inlet hole 311. At this time, the liquid storage chamber c continues to replenish the liquid medium. In this way, the intermittently operating liquid control mechanism 5 can maximize the evaporation space of the liquid medium, thereby improving the evaporation efficiency. The multi-way valve 15 has at least three, and at least two, inlet pipes 31. A sealing block is installed inside each inlet pipe 31. Each inlet pipe 31 is connected to a first connecting pipe 14 via the multi-way valve 15. The first connecting pipe 14 is connected to the liquid pipe 3 via a second flange 19. To ensure the suction plate 51 can move stably up and down, at least two connecting rods 53 are needed for balance. To ensure the thrust of the liquid inlet is less than the weight of the suction plate 51 after water absorption, at least one inlet pipe 31 without a sealing block must be retained. This way, when other inlet pipes cannot discharge liquid, the liquid thrust will not fully act on the sealing block, allowing the inlet pipe 31 to continuously supply liquid, reducing the thrust. Furthermore, the number of inlet pipes 31 into which liquid medium can flow into the storage chamber c is reduced, still minimizing the need for liquid medium replenishment and not affecting the improved evaporation efficiency of the liquid control mechanism 5.

[0033] In some optional embodiments, the water-absorbing plate 51 is provided with a plurality of first through holes 511, the first partition plate 11 is provided with a plurality of second through holes, and the second partition plate 12 is provided with a plurality of third through holes. The first through holes 511, the second through holes and the third through holes are provided in a one-to-one correspondence, and the heat-absorbing tube assembly 4 passes through the first through holes 511, the second through holes and the third through holes.

[0034] Specifically, the heat-absorbing tube 41 extends partially into the evaporation chamber a, dividing it into a through section and a heat-absorbing section. The through section is located inside the evaporation chamber a, while the heat-absorbing section is located between the evaporation chamber a and the liquid storage chamber c. The partial extension of the heat-absorbing tube 41 into the evaporation chamber a prevents the tube opening from being too low, which could easily lead to blockage by the liquid medium and affect steam discharge efficiency. Several sliding through holes are provided on the water-absorbing plate 51, and the through section of the heat-absorbing tube 41 passes through these sliding through holes, slidably connecting the heat-absorbing tube 41 to the sliding through holes. The water-absorbing plate 51 moves on the through section, providing greater stability. The top of the evaporation chamber a has an inverted funnel-shaped structure. A second connecting pipe 16 is provided at the top of the evaporation chamber a, connecting to the gas pipe 2 via a first flange 17. The inverted funnel-shaped structure ensures that when steam rises vertically, it can smoothly enter the gas pipe 2 along the inclined surface of the top of the evaporation chamber a.

[0035] In some optional embodiments, the heat absorber assembly 4 is provided with a plurality of heat absorber tubes 41, each heat absorber tube 41 passing through a corresponding first through hole 511, a second through hole and a third through hole.

[0036] In some alternative embodiments, the evaporator body 1 includes an isolation cylinder 13 located in the region of the evaporation chamber a, with a gap between the isolation cylinder 13 and the evaporator body 1, and a connecting rod 53 disposed in the gap.

[0037] In some optional embodiments, the gap between the isolation cylinder 13 and the evaporation body 1 is configured to correspond to the liquid inlet pipe 31.

[0038] In some optional embodiments, the evaporator body 1 further includes a first connecting pipe 14 and a multi-way valve 15. One end of the first connecting pipe 14 is connected to the multi-way valve 15, and the multi-way valve 15 is connected to a plurality of liquid inlet pipes 31 respectively. The other end of the first connecting pipe 14 is connected to the liquid pipe 3.

[0039] In some alternative embodiments, the inner surface of the top of the evaporation body 1 forming the evaporation chamber a is funnel-shaped.

[0040] In some optional embodiments, the evaporator body 1 further includes a second connecting pipe 16, one end of which is connected to the top of the evaporation chamber a, and the other end of which is connected to the gas pipe 2 via a first flange 17; it also includes an inner sleeve 18, which is disposed inside the second connecting pipe 16 and the gas pipe 2, and has a heat insulation gap between the inner sleeve 18 and the second connecting pipe 16 and the gas pipe 2 respectively.

[0041] Specifically, one end of the second connecting pipe 16 is connected to the top of the evaporation chamber a, and the other end of the second connecting pipe 16 is connected to the gas pipe 2 through the first flange 17. The inner sleeve 18 is set inside the second connecting pipe 16 and the gas pipe 2. The inner sleeve 18 has heat insulation gaps between the second connecting pipe 16 and the gas pipe 2 respectively, which can effectively play a heat preservation role and is suitable for long-distance steam transmission. Moreover, the heat insulation gap is also connected to the evaporation chamber a, so that steam not only enters the inner sleeve 18, but also enters the heat insulation gap. However, the end of the heat insulation gap is a closed end, which is the end away from the evaporation chamber a. Therefore, during long-distance transmission, the steam in the heat insulation gap will play a role in continuously maintaining the high temperature of the inner sleeve 18. The closed end is to prevent the steam from losing too much heat at the end and liquefying, and the liquid medium flowing into the condenser.

[0042] This application also provides a heat exchange system, which includes: an evaporator, a condenser 6, a gas pipeline 2, and a liquid pipeline 3. The evaporator and the condenser 6 are connected by the gas pipeline 2, and the evaporator and the condenser 6 are connected by the liquid pipeline 3. The evaporator is any of the evaporators mentioned above.

[0043] Specifically, the evaporation device includes an evaporation chamber a, a heat absorption chamber b, a liquid storage chamber c, and a heat absorption tube assembly 4. The two ends of the heat absorption tube assembly 4 are connected to the evaporation chamber a and the liquid storage chamber c, respectively. The liquid storage chamber c is also connected to a liquid pipe 3, and the evaporation chamber a is also connected to a gas pipe 2. When the split heat pipe is used, the gas pipe 2 is connected to the gas inlet of the condensing device 6, and the liquid pipe 3 is connected to the liquid outlet of the condensing device 6. In this way, the liquid medium evaporates and absorbs heat to become steam under the action of the evaporation device. After entering the condensing device 6 through the gas pipe 2, it releases heat and liquefies back into the liquid medium and then flows back to the liquid storage chamber c through the liquid pipe 3. As the liquid volume in the liquid storage chamber c increases, the liquid will be drawn into the heat absorption tube assembly 4 and the evaporation chamber a for evaporation again. In the continuous cycle, the heat of the evaporation device is transferred to the condensing device 6, realizing the effect of heat exchange.

[0044] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
