Description

Technical Field

[0001] The invention belongs to the field of safety facilities specially provided for floating nuclear power platforms, and in particular relates to an evaporation device and a heat exchange system. Background Art

[0002] An efficient heat transfer system is used to transfer heat from one place to another. An efficient heat transfer device consists of a sealed metal pipe system filled with a working medium. The heat transfer device is usually divided into three parts: the evaporation section, the condensation section, and the liquid ring 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 evaporated into steam in the evaporator. The steam rises in the heat pipe, takes away the heat, and then enters the condenser. The condensation section is located where heat needs to be transferred. The external ambient temperature of the condensation section is low, and the steam cools down inside the condensation section and returns to liquid. In this way, the heat is released to the surrounding environment of the condensation section. In the liquid ring section, the liquid medium will spontaneously return from the condenser to the evaporation section to form a cycle. This cycle process can continuously transfer heat from the heat source to where it is needed. The heat exchange system has the characteristics of high efficiency, reliability, and energy saving. It can quickly transfer heat between the heat source and the radiator, and can effectively solve the 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 end of the condenser, the evaporation chamber is connected to the air inlet end of the condenser, and the heat absorption tube uses capillary force and pressure difference to absorb the liquid medium from the liquid storage chamber into the heat absorption tube for evaporation. However, the traditional heat absorption tube may not be fully evaporated, resulting in the presence of liquid medium and steam in the heat absorption tube at the same time. The liquid will evaporate again after entering the evaporation chamber. If there is a lot of liquid medium, it cannot be completely evaporated in the evaporation chamber. Instead, it will remain in the evaporation chamber, resulting in blockage of the outlet of the heat absorption tube, thereby resulting in the steam in the heat absorption tube cannot be discharged, affecting the evaporation efficiency of the liquid medium. In addition, the existing evaporation device will also cause heat loss when transmitting steam over long distances. Summary of the invention

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] An efficient heat transfer system is used to transfer heat from one place to another. An efficient heat transfer device consists of a sealed metal pipe system filled with a working medium. The heat transfer device is usually divided into three parts: the evaporation section, the condensation section, and the liquid ring 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 evaporated into steam in the evaporator. The steam rises in the heat pipe, takes away the heat, and then enters the condenser. The condensation section is located where heat needs to be transferred. The external ambient temperature of the condensation section is low, and the steam cools down inside the condensation section and returns to liquid. In this way, the heat is released to the surrounding environment of the condensation section. In the liquid ring section, the liquid medium will spontaneously return from the condenser to the evaporation section to form a cycle. This cycle process can continuously transfer heat from the heat source to where it is needed. The heat exchange system has the characteristics of high efficiency, reliability, and energy saving. It can quickly transfer heat between the heat source and the radiator, and can effectively solve the 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 end of the condenser, the evaporation chamber is connected to the air inlet end of the condenser, and the heat absorption tube uses capillary force and pressure difference to absorb the liquid medium from the liquid storage chamber c into the heat absorption tube for evaporation. However, the traditional heat absorption tube may not be fully evaporated, resulting in the presence of liquid medium and steam in the heat absorption tube at the same time. The liquid will evaporate again after entering the evaporation chamber. If there is a lot of liquid medium, it cannot be completely evaporated in the evaporation chamber. Instead, it will remain in the evaporation chamber, resulting in blockage of the outlet of the heat absorption tube, thereby resulting in the steam in the heat absorption tube cannot be discharged, affecting the evaporation efficiency of the liquid medium. In addition, the existing evaporation device will also cause heat loss when transmitting steam over long distances.

[0026] The embodiment of the present invention provides an evaporation device with high evaporation efficiency and low heat loss in long-distance steam transmission.

[0027] The present application provides an evaporation device, which includes: an evaporation body 1, which has a accommodating space inside, a first partition plate 11, which is arranged inside the evaporation body 1; a second partition plate 12, which is arranged inside the evaporation body 1 and is set at a preset distance from the first partition plate 11, and the first partition plate 11 and the second partition plate 12 divide the evaporation body 1 into an evaporation chamber a, a heat absorption chamber b and a liquid storage chamber c; a gas pipeline 2, which is connected to the evaporation chamber a; a liquid pipeline 3, which is provided with a plurality of liquid inlet pipelines 31, and a liquid inlet hole 311 is provided on the wall forming the liquid inlet pipeline 31; a heat absorption pipe assembly 4, which is arranged in the heat absorption chamber b, and the heat absorption pipe assembly 4 is respectively connected to the evaporation chamber a and the liquid storage chamber c; a hydraulic control mechanism 5, which includes a water absorption plate 51 and a plurality of blocking components, the water absorption plate 51 is arranged in the evaporation chamber a, one end of each blocking component is connected to the water absorption plate 51, and the other end of the blocking component can extend to the inside of the liquid inlet pipeline 31, and the number of blocking components is 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 pipe assembly 4. The two ends of the heat absorption pipe assembly 4 are respectively connected to the evaporation chamber a and the liquid storage chamber c. The liquid storage chamber c is also connected to the liquid pipeline 3. The evaporation chamber a is also connected to the gas pipeline 2. When the separate heat pipe is in use, the gas pipeline 2 is connected to the air inlet of the condensing device 6, and the liquid pipeline 3 is connected to the liquid outlet of the condensing device 6. In this way, the liquid medium evaporates and absorbs heat into steam under the action of the evaporation device. After entering the condensing device 6 along the gas pipeline 2, it releases heat and liquefies to recover into a liquid medium and then flows back to the liquid storage chamber c through the liquid pipeline 3. As the amount of liquid in the liquid storage chamber c increases, the liquid will be sucked into the heat absorption pipe assembly 4 and the evaporation chamber a for evaporation again. In the continuous circulation process, the heat of the evaporation device is transferred to the condensing device 6 to achieve the effect of heat exchange.

[0029] Furthermore, when the liquid medium in the evaporation chamber a does not have time to evaporate, the blocking component blocks the liquid inlet hole 311 of the liquid inlet pipe 31, thereby controlling the flow of the liquid inlet pipe 31 and reducing the liquid entering the liquid storage chamber c, thereby avoiding excessive accumulation of liquid medium in the evaporation chamber a and affecting the discharge of steam in the heat absorption pipe assembly 4, effectively improving the evaporation efficiency of the liquid medium, and the hydraulic control mechanism 5 uses the water absorption plate 51 to absorb the liquid medium that does not have time to evaporate, avoiding blocking the inlet of the heat absorption pipe assembly 4, and the water absorption plate 51 presses down the blocking element 52 due to its own weight after absorbing the liquid, thereby blocking part of the liquid inlet pipe 31, thereby achieving the effect of reducing the liquid inlet flow rate and improving the evaporation efficiency of the liquid medium.

[0030] Optionally, the hydraulic control mechanism 5 includes a water absorption plate 51, a blocking element 52 and a connecting rod 53, wherein the connecting rod 53 connects the blocking element 52 and the water absorption plate 51 respectively, and the blocking element 52 is a blocking block. The water absorption plate 51 is installed inside the evaporation chamber a, and the blocking block is installed inside the liquid inlet pipe 31 set in the liquid storage chamber c. The liquid inlet pipe 31 is connected to the liquid pipe 3, and the water absorption plate 51 and the blocking block are connected through the connecting rod 53. An isolation cylinder 13 is set between the evaporation chambers a, and the gap between the isolation cylinder 13 and the inner surface of the evaporation body 1 is set corresponding to the liquid inlet pipe 31. The gap between the isolation cylinder 13 and the inner surface of the evaporation body 1 is for the connecting rod 53 to pass through. The liquid inlet pipe 31 is provided with a liquid inlet hole 311, which is used to push the blocking block to block the liquid inlet hole 311 when the weight of the water absorption plate 51 increases after absorbing liquid. After the liquid in the water absorption plate 51 evaporates, its weight reduces the buoyancy of the liquid inlet pipe 31, pushing the blocking block away from the liquid inlet hole 311. As can be seen from the above, the evaporation device uses the heat absorption pipe assembly 4 to evaporate and absorb liquid. Although the entire evaporation device is immersed in the heat source, the heat absorption pipe assembly 4 cannot guarantee that the liquid medium is completely evaporated. Therefore, the liquid medium in the heat absorption pipe assembly 4 will also flow into the evaporation chamber a and evaporate again. If there is too much liquid accumulation, a large amount of liquid medium will continue to enter the liquid storage chamber c, which will easily cause the liquid medium to fill the evaporation chamber a, and also affect the steam from entering the gas pipeline 2, reducing the efficiency of steam generation. When the liquid is accumulated in the evaporation chamber a, the liquid flow rate of the liquid inlet pipe 31 to the liquid storage chamber c can be controlled to be reduced, thereby providing the evaporation chamber a and the heat absorption pipe assembly 4 with enough space for steam discharge, indirectly improving the evaporation efficiency.

[0031] The hydraulic control mechanism 5 mainly achieves the operation of reducing the amount of liquid entering by blocking the liquid inlet hole 311 with a blocking block, and the blocking block forms a linkage mechanism with the water absorption plate 51 through a connecting rod 53. At the beginning, the blocking block is above the liquid inlet hole 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 to reduce the liquid medium in the evaporation chamber a. After the water absorption plate 51 absorbs the liquid, its weight increases, and the blocking block will be pressed down by the connecting rod 53 to generate displacement. The blocking block moves to the position of the liquid inlet hole 311 to block the liquid inlet hole 311. At this time, no liquid flows out of the liquid inlet pipe 31, so that 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 achieving the effect of improving the evaporation efficiency.

[0032] The above introduction of how the hydraulic control mechanism 5 improves the evaporation efficiency only introduces one working state. In order to ensure the automatic operation of the hydraulic control mechanism 5, the hydraulic control mechanism 5 needs to be designed as follows: the bottom end of the liquid inlet pipe 31 is connected to the liquid pipe 3, the connecting rod 53 is connected to the blocking block, the liquid inlet hole 311 is opened on the side wall of the liquid inlet pipe 31, the blocking block is piston-connected to the inner wall of the liquid inlet pipe 31, and the liquid inlet hole 311 is within the moving range of the blocking block. The blocking block and the liquid inlet pipe 31 are piston-type. When the weight of the water absorption plate 51 is greater than the thrust of the liquid out of the liquid inlet pipe 31, the blocking block moves downward to block the liquid inlet hole 311, cutting off the replenishment of the liquid medium. After the liquid medium is fully evaporated, the weight reduction of the water absorption plate 51 is less than the thrust of the liquid out of the liquid inlet hole 311, and the blocking 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 intermittent and non-stop hydraulic control mechanism 5 can provide the evaporation space of the liquid medium to the maximum extent, thereby improving the evaporation efficiency. The multi-way valve 15 is provided with at least three and at least two liquid inlet pipes 31, and a blocking block is installed in the liquid inlet pipe 31. Each liquid inlet pipe 31 is connected to the first connecting pipe 14 through the multi-way valve 15, and the first connecting pipe 14 is connected to the liquid pipe 3 through the second flange 19. In order to ensure that the water absorption plate 51 can move up and down stably, at least two connecting rods 53 are required to balance, and in order to ensure that the thrust of the liquid inlet is less than the weight of the water absorption plate 51 after absorbing water, it is necessary to retain at least one liquid inlet pipe 31 without a blocking block installed, so that when other liquid inlet pipes cannot discharge liquid, the thrust of the liquid will not completely act on the blocking block, and the liquid inlet pipe 31 can continue to inlet liquid, reducing the thrust of the liquid inlet, and the number of liquid inlet pipes 31 that can flow into the liquid storage chamber c into the liquid medium is reduced, which can still reduce the replenishment of the liquid medium, and does not affect the liquid control mechanism 5 to improve the evaporation efficiency.

[0033] In some optional embodiments, the water absorption plate 51 is provided with a plurality of first through holes, the first partition plate 11 is provided with a plurality of second through holes, the second partition plate 12 is provided with a plurality of third through holes, the first through holes, the second through holes and the third through holes are provided one by one, and the heat absorption tube assembly 4 passes through the first through holes, the second through holes and the third through holes.

[0034] Specifically, the heat absorption tube 41 partially extends into the evaporation chamber a to divide the heat absorption tube 41 into a through section and a heat absorption section. The through section is located inside the evaporation chamber a, and the heat absorption section is located between the evaporation chamber a and the liquid storage chamber c. The heat absorption tube 41 partially extends into the evaporation chamber a to avoid the pipe mouth of the heat absorption tube 41 being too low, which may cause the pipe mouth to be easily blocked by the liquid medium and affect the steam discharge efficiency. A plurality of sliding through holes are arranged on the water absorption plate 51, and the through section of the heat absorption tube 41 penetrates the sliding through holes, and the heat absorption tube 41 is slidably connected to the sliding through holes. The water absorption plate 51 moves on the through section more smoothly up and down, and the top of the evaporation chamber a is an inverted funnel-shaped structure. A second connecting pipe 16 is arranged on the top of the evaporation chamber a, and the second connecting pipe 16 is connected to the gas pipeline 2 through the first flange 17. The inverted funnel-shaped structure is to enable the steam to smoothly enter the gas pipeline 2 along the inclined surface of the top of the evaporation chamber a when it is vertically upward.

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

[0036] In some optional embodiments, the evaporation body 1 includes an isolation tube 13 located in the area of ​​the evaporation chamber a, and there is a gap between the isolation tube 13 and the evaporation body 1, and the connecting rod 53 is arranged in the gap.

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

[0038] In some optional embodiments, the evaporation body 1 also 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, the multi-way valve 15 is respectively connected to multiple liquid inlet pipes 31, and the other end of the first connecting pipe 14 is connected to the liquid pipe 3.

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

[0040] In some optional embodiments, the evaporation body 1 also 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 the second connecting pipe 16 is connected to the gas pipeline 2 through a first flange 17; it also includes an inner sleeve 18, which is arranged inside the second connecting pipe 16 and the gas pipeline 2, and there is an insulating gap between the inner sleeve 18 and the second connecting pipe 16 and the gas pipeline 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 pipeline 2 through the first flange 17. The inner sleeve 18 is arranged inside the second connecting pipe 16 and the gas pipeline 2. There is an insulating gap between the inner sleeve 18 and the second connecting pipe 16 and the gas pipeline 2 respectively, which can effectively play a role in heat preservation and is suitable for long-distance steam transmission. Moreover, the insulating gap is also connected to the evaporation chamber a, so that the steam not only enters the inner sleeve 18, but also enters the insulating gap. However, the end of the insulating gap is a closed end, and the end is the end far away from the evaporation chamber a. Therefore, during the long-distance transmission process, the steam in the insulating 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 to produce liquefaction, and the liquid medium flows into the condenser.

[0042] The present application also provides a heat exchange system, which includes: an evaporation device, a condensation device 6, a gas pipeline 2 and a liquid pipeline 3, the evaporation device and the condensation device 6 are connected through the gas pipeline 2, the evaporation device and the condensation device 6 are connected through the liquid pipeline 3, and the evaporation device is any of the evaporation devices 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 pipe assembly 4. The two ends of the heat absorption pipe assembly 4 are respectively connected to the evaporation chamber a and the liquid storage chamber c. The liquid storage chamber c is also connected to the liquid pipeline 3. The evaporation chamber a is also connected to the gas pipeline 2. When the separate heat pipe is in use, the gas pipeline 2 is connected to the air inlet of the condensing device 6, and the liquid pipeline 3 is connected to the liquid outlet of the condensing device 6. In this way, the liquid medium evaporates and absorbs heat into steam under the action of the evaporation device. After entering the condensing device 6 along the gas pipeline 2, it releases heat and liquefies to recover into a liquid medium and then flows back to the liquid storage chamber c through the liquid pipeline 3. As the amount of liquid in the liquid storage chamber c increases, the liquid will be sucked into the heat absorption pipe assembly 4 and the evaporation chamber a for evaporation again. In the continuous circulation process, the heat of the evaporation device is transferred to the condensing device 6 to achieve the effect of heat exchange.

[0044] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
