Description

Technical Field

[0001] This application relates to the field of phase change heat transfer technology, specifically to an evaporation module, a phase change heat transfer device, and electrical equipment. Background Technology

[0002] A phase change heat transfer device is a device that uses the phase change of a working fluid between a liquid and a gaseous state to efficiently transfer heat. It has a high thermal conductivity and can be well adapted to the heat dissipation requirements of high-power electrical equipment.

[0003] The phase change heat exchanger includes an evaporation module. The evaporation module comprises an evaporation shell, within which the working fluid is primarily liquid. In practical applications, the liquid working fluid within the evaporation module exchanges heat with the heat source components. The heat generated by the heat source components is transferred to the liquid working fluid, causing a phase change and absorbing the heat generated by the heat source components. Generally, the liquid working fluid within the evaporation module should cover the area in contact between the evaporation shell and the heat source components, or even cover the heat source components themselves. This allows for better cooling of the heat source components through evaporative cooling. However, in actual use, due to factors such as installation reliability and the installation environment (e.g., underwater environments), the phase change heat exchanger may inevitably tilt. This can alter the distribution of the liquid working fluid within the evaporation module, potentially resulting in the liquid working fluid failing to cover the area in contact with the heat source components, or failing to cover the heat source components at all. This, in turn, affects the heat dissipation effect of the heat source components.

[0004] Therefore, how to provide a solution to overcome or alleviate the above-mentioned defects remains a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] This application provides an evaporation module, a phase change heat exchange device, and an electrical device. The evaporation module has a liquid retention zone in its evaporation chamber. The liquid retention zone can intercept the liquid working fluid when the evaporation module is tilted, thereby improving the evaporation heat absorption performance of the evaporation module and enhancing the heat dissipation effect of the heat source component.

[0006] To solve the above-mentioned technical problems, this application provides an evaporation module for use in a phase change heat exchange device, the phase change heat exchange device further including a condensation module, the evaporation module and the condensation module being connected and arranged along a first direction; the evaporation module includes: an evaporation shell having an evaporation cavity, the evaporation shell including a first wall plate and a second wall plate disposed opposite to each other along the first direction, the first wall plate being located on the side of the second wall plate away from the condensation module along the first direction, the first wall plate being provided with a plurality of mating areas spaced apart along a second direction, the mating areas corresponding to heat source components, the second direction forming an angle with the first direction; a blocking structure including at least one blocking part disposed within the evaporation cavity, at least one of the first wall plate and the second wall plate being connected to the blocking part, the blocking part defining a liquid-retaining area within the evaporation cavity, the liquid-retaining area being used to contain liquid working fluid, the projection of the liquid-retaining area along the first direction onto the first wall plate covering at least one of the mating areas.

[0007] In some possible implementations, the liquid-retaining zone has two side boundary stops and one bottom boundary stop, the two side boundary stops being spaced apart along the second direction, and the bottom boundary stop being located below the liquid-retaining zone along a third direction. Either the first direction or the second direction forms an angle with the third direction. At least a portion of the side boundary stops and the bottom boundary stops is formed by the blocking portion. The liquid-retaining zone also has an inlet and outlet located on the side of the liquid-retaining zone away from the bottom boundary stop along the third direction. The liquid-retaining zone is connected to other areas within the evaporation chamber through the inlet and outlet.

[0008] In some possible implementations, at least a portion of the side boundary stop has a protrusion extending in the second direction at one end away from the bottom boundary stop, the protrusion being located on the side of the side boundary stop facing the liquid retention area.

[0009] In some possible implementations, the evaporation shell further includes a top wall plate and a bottom wall plate disposed opposite each other along the third direction, the bottom wall plate being connected to the blocking portion, the blocking portion having an extending length along the third direction; the number of liquid-retaining zones is multiple, and each liquid-retaining zone is arranged along a second direction; the bottom wall plate forms the bottom boundary stop of each liquid-retaining zone; the blocking portion is located between two adjacent liquid-retaining zones and forms the side boundary stop shared by two adjacent liquid-retaining zones.

[0010] In some possible implementations, the blocking portion includes a bottom plate and two side plates, the two side plates being spaced apart along the second direction, the bottom plate and the two side plates being connected, the bottom plate forming the bottom boundary stop of the liquid-retaining area, and the side plates forming the side boundary stops of the liquid-retaining area.

[0011] In some possible implementations, at least one of the bottom plate and the two side plates is provided with an opening.

[0012] In some possible implementations, the blocking portion includes a baffle plate and a heat dissipation portion. The heat dissipation portion includes at least three heat dissipation plates spaced apart along the second direction. A sub-channel extending along the third direction is formed between two adjacent heat dissipation plates. The baffle plate is located on the lower side of the heat dissipation portion along the third direction, and the baffle plate and the heat dissipation portion are spaced apart along the third direction. Either the first direction or the second direction forms an angle with the third direction. Two heat dissipation plates located at both ends along the second direction in the heat dissipation portion form the side boundary stop of the liquid retention area, and the baffle plate forms the bottom boundary stop of the liquid retention area.

[0013] In some possible implementations, the blocking structure defines a first liquid-retaining region and a second liquid-retaining region within the evaporation chamber, the first liquid-retaining region and the second liquid-retaining region being located at two ends of the evaporation chamber along the second direction, respectively; the first wall panel includes a first end region and a second end region, the first end region and the second end region being located at two ends of the first wall panel along the second direction, each of the first end region and the second end region being provided with at least one mating region, the projection of the first liquid-retaining region along the first direction onto the first wall panel being able to cover the mating region of the first end region, and the projection of the second liquid-retaining region along the first direction onto the first wall panel being able to cover the mating region of the second end region.

[0014] In some possible implementations, the first wall panel further includes a central region located between the first end region and the second end region, and the central region also has at least one of the mating regions.

[0015] In some possible implementations, both the first wall panel and the second wall panel are connected to the blocking portion; or, one of the first wall panel and the second wall panel is connected to the blocking portion, and the other of the first wall panel and the blocking portion has a predetermined gap along the first direction.

[0016] Secondly, this application also provides a phase change heat exchange device, including an evaporation module and a condensation module, wherein the evaporation module and the condensation module are connected, and the evaporation module is any of the evaporation modules involved in the first aspect or any of the implementations of the first aspect.

[0017] Thirdly, this application also provides an electrical device, including a housing, a heat source component, and a phase change heat exchange device. The housing includes a power chamber and a heat dissipation chamber. The heat source component is disposed in the power chamber. The phase change heat exchange device is the aforementioned phase change heat exchange device. The heat source component is disposed in the mating area. The condensation module is located in the heat dissipation chamber.

[0018] After reading and understanding the accompanying diagrams and detailed descriptions, the other aspects will become clear.

[0019] In this embodiment, the evaporation module of the phase change heat exchanger includes an evaporation shell and a blocking structure disposed within the evaporation shell. The blocking structure includes at least one blocking portion. At least one of the first wall plate and the second wall plate in the evaporation shell is connected to the blocking portion. The blocking portion can define at least one liquid-retaining zone within the evaporation chamber of the evaporation shell. The projection of the liquid-retaining zone along a first direction onto the first wall plate can cover at least one mating area. When the evaporation module is tilted, the liquid working fluid in the evaporation chamber will flow towards the relatively lower side of the evaporation chamber. However, due to the blocking portion and the liquid-retaining zone, some of the liquid working fluid will be intercepted in the liquid-retaining zone, instead of flowing entirely towards the relatively lower side of the evaporation chamber. This allows the mating area covered by the liquid-retaining zone along the first direction to still have a relatively large amount of liquid working fluid available for use, thereby improving the overall evaporation heat absorption performance of the evaporation module in the tilted position.

[0020] Furthermore, the setting of the blocking part can also increase the contact area between the inside of the evaporation module and the liquid working fluid, that is, it can increase the effective evaporation area inside the evaporation module, which is of relatively positive significance for improving the evaporation heat absorption performance of the evaporation module.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] In the description of the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0025] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, "linking" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0026] In the description of embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0027] Please refer to Figures 1-3 , Figure 1 This is a schematic diagram of the structure of an electrical device provided in an embodiment of this application. Figure 2 for Figure 1 Exploded view of electrical equipment in the middle. Figure 3 This is a structural diagram of the phase change heat exchanger mounted on the partition plate.

[0028] like Figures 1-3 As shown, this application embodiment provides an electrical device 100. The electrical device 100 can be a frequency converter, inverter, rectifier, energy storage converter, charging device, power supply device, or other devices that generate heat during operation and have heat dissipation requirements. Here, this application embodiment does not limit the type of electrical device 100.

[0029] Electrical equipment 100 includes a housing 1000 and a heat source component 2000. The housing 1000 forms the external body of the electrical equipment 100 and provides a mounting base for the heat source component 2000, etc. Figure 1 and Figure 2 The enclosure 1000 is equipped with a partition 1300, which divides the interior of the enclosure 1000 into a power chamber 1100 and a heat dissipation chamber 1200. The power chamber 1100 can be a sealed chamber, where the heat source components 2000 can be housed to achieve relatively better protection and reduce the intrusion of external dust, moisture, etc. The heat dissipation chamber 1200 is used to introduce external airflow to cool down the heat source components 2000 and other components within the power chamber 1100.

[0030] Here, the embodiments of this application do not limit the specific type of heat source component 2000. In practical applications, those skilled in the art can determine it based on the type of electrical equipment 100, etc. For example, the heat source component 2000 can be a power semiconductor device, such as an insulated-gate bipolar transistor (IGBT) or a metal-oxide-semiconductor field-effect transistor (MOSFET). Of course, the electrical components provided in the electrical equipment 100 are not limited to the aforementioned heat source component 2000; they can also include other devices, such as switching devices, capacitors, inductors, reactances, etc., which will not be described in detail here.

[0031] For ease of explanation, embodiments of this application also define a first direction X, a second direction Y, and a third direction Z. Any two of these three can form an angle, such as 90 degrees. The first direction X is the arrangement direction of the power chamber 1100 and the heat dissipation chamber 1200. When the partition 1300 is a flat plate, the first direction X can also be understood as the normal direction of the partition 1300.

[0032] The enclosure 1000 is also provided with an air inlet 1400 and an air outlet 1500, both of which are connected to the heat dissipation chamber 1200. External airflow can enter the heat dissipation chamber 1200 through the air inlet 1400 and can be discharged through the air outlet 1500. The shape, number, and location of the air inlet 1400 and the air outlet 1500 are not limited here; in practical applications, those skilled in the art can design them according to specific needs.

[0033] In some implementations, the electrical equipment 100 may also include an air supply component 4000, which may be a centrifugal fan, an axial fan, a mixed-flow fan, etc. The air supply component 4000 may be located inside or outside the heat dissipation chamber 1200. In short, the air supply component 4000 can provide a forced driving force for the flow of external airflow in the heat dissipation chamber 1200 to improve the heat exchange effect.

[0034] In specific installation, the air supply component 4000 can be set near the air inlet 1400 or near the air outlet 1500, and there is no limitation here.

[0035] It should be understood that the aforementioned air supply component 4000 is not a necessary component for the electrical equipment 100 provided in the embodiments of this application. In some other implementations of the embodiments of this application, the aforementioned air supply component 4000 may not be provided. In this case, the heat exchange chamber 1200 and the external environment may rely on natural convection for heat exchange.

[0036] In this embodiment of the application, the electrical equipment 100 further includes a phase change heat exchange device 3000.

[0037] Combination Figure 2 The phase change heat exchange device 3000 includes an evaporation module 3100 and a condensation module 3200. The evaporation module 3100 contains an evaporation chamber, and the condensation module 3200 contains a condensation chamber. The evaporation module 3100 and the condensation module 3200 are connected, and the evaporation chamber and the condensation chamber are interconnected. A heat exchange medium circulates within the evaporation chamber and the condensation chamber. This heat exchange medium is specifically a two-phase medium, such as a Freon-based, hydrocarbon-based, or inorganic compound-based medium capable of undergoing a two-phase change, thereby achieving heat absorption and transfer.

[0038] The evaporation module 3100 can be installed on the partition 1300. Specific installation methods include welding, screw connection, etc., which are not limited here. After installation, the evaporation module 3100 can be located on the side of the partition 1300 facing the power chamber 1100, or it can be located on the side of the partition 1300 facing the heat dissipation chamber 1200. That is, the evaporation module 3100 can be located in either the power chamber 1100 or the heat dissipation chamber 1200, which is not limited here. In short, as long as the evaporation module 3100 can exchange heat with the power chamber 1100, it is acceptable. The condensation module 3200 can be located on the side of the partition 1300 facing the heat dissipation chamber 1200, so as to perform condensation heat exchange using the external airflow introduced into the heat dissipation chamber 1200.

[0039] The number of heat source components 2000 can be one or more, and there is no limitation on this. The heat source component 2000 can be installed in the evaporation module 3100 so as to exchange heat with the heat exchange medium in the evaporation module 3100, thereby achieving cooling of the heat source component 2000.

[0040] Please refer to Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of a phase change heat exchange device. Figure 5 This is a cross-sectional view of the phase change heat exchanger perpendicular to the second direction.

[0041] In some implementations, such as Figure 4 As shown, in the phase change heat exchanger 3000, the evaporation module 3100 and the condensation module 3200 are arranged along the first direction X.

[0042] The evaporation module 3100 may include an evaporation shell 3110, and an evaporation chamber 3111 may be formed inside the evaporation shell 3110. The heat exchange medium in the evaporation chamber 3111 is mainly a liquid medium. Figure 5 The evaporator shell 3110 includes a first wall panel 3112, a second wall panel 3113, a top wall panel 3114, a bottom wall panel 3115, and two side wall panels 3117. The first wall panel 3112 and the second wall panel 3113 are arranged opposite each other along a first direction X, with the first wall panel 3112 located on the side of the second wall panel 3113 facing away from the condenser module 3200 along the first direction X. The two side wall panels 3117 are arranged opposite each other along a second direction Y. The top wall panel 3114 and the bottom wall panel 3115 are arranged opposite each other along a third direction Z. In actual installation, the top wall panel 3114 is located above the bottom wall panel 3115 along the direction of gravity. The first wall panel 3112, the second wall panel 3113, the top wall panel 3114, the bottom wall panel 3115, and the two side wall panels 3117 together define the evaporator chamber 3111.

[0043] The first wall panel 3112 is provided with a plurality of mating regions 3112A arranged at intervals along the second direction Y, and the mating regions 3112A correspond to the heat source components 2000. The above correspondence can be one-to-one, that is, one mating region 3112A corresponds to one heat source component 2000, and correspondingly, multiple mating regions 3112A can each correspond to multiple heat source components 2000. Alternatively, the above correspondence can also be many-to-one, that is, multiple mating regions 3112A can also correspond to multiple different heating parts of a heat source component 2000.

[0044] In some implementations, the mating region 3112A can be a solid plate segment on the first wall panel 3112, and the heat source component 2000 can be disposed on the side of the mating region 3112A facing away from the evaporation chamber 3111. In this case, the heat exchange path between the heat source component 2000 and the liquid working fluid in the evaporation chamber 3111 is: heat source component 2000 → first wall panel 3112 → liquid working fluid.

[0045] The heat source component 2000 can be in direct contact with the first wall panel 3112.

[0046] Alternatively, a thermal interface material (TIM) such as thermally conductive silicone grease can be applied between the heat source component 2000 and the first wall panel 3112. In this case, the heat source component 2000 and the first wall panel 3112 are in indirect contact. The thermal interface material can fill the gap between the heat source component 2000 and the first wall panel 3112, reducing the contact thermal resistance between them and improving the heat exchange efficiency.

[0047] In some implementations, the mating region 3112A can be a through hole on the first wall panel 3112, and the heat source component 2000 can be at least partially embedded in the through hole, allowing it to directly contact the liquid working fluid in the evaporation chamber 3111. In this case, the heat exchange path between the heat source component 2000 and the liquid working fluid in the evaporation chamber 3111 is: heat source component 2000 → liquid working fluid, and the heat transfer efficiency from the heat source component 2000 to the liquid working fluid is relatively high.

[0048] The condenser module 3200 may include multiple condenser units 3210.

[0049] In some implementation methods, combined Figure 4 and Figure 5Each condenser unit 3210 can be arranged at intervals along the second direction Y, and each condenser unit 3210 has a condensation cavity 3211. The condensation cavity of the condensation module 3200 can include each condensation cavity 3211. The second wall plate 3113 is provided with a connecting hole 3113A, and the condenser unit 3210 can be sealed and installed on the second wall plate 3113, so that the condensation cavity 3211 can be connected to the evaporation cavity 3111 through the connecting hole 3113A. In this implementation, the heat exchange medium can be directly circulated between the condensation cavity 3211 and the evaporation cavity 3111.

[0050] When the phase change heat exchanger 3000 is in operation, the heat generated by the heat source component 2000 is transferred to the liquid working fluid in the evaporation chamber 3111 via the first wall plate 3112 (or directly). After absorbing heat, the liquid working fluid undergoes a phase change and forms a gaseous working fluid. The gaseous working fluid enters the condensation chamber 3211 of the condenser unit 3210 through the connecting hole 3113A. The gaseous working fluid exchanges heat with the air in the condensation module 3200 and the heat dissipation chamber 1200, and can condense into a liquid working fluid in the condensation module 3200. The liquid working fluid can then flow back to the evaporation module 3100. Thus, the heat exchange working fluid can circulate between the evaporation module 3100 and the condensation module 3200, and can continuously transfer the heat generated by the heat source component 2000 to the heat dissipation chamber 1200 through the phase change between the liquid and gaseous working fluids, and finally be discharged through the external airflow introduced into the heat dissipation chamber 1200.

[0051] In addition, in some other implementations of the embodiments of this application, the condensation module 3200 may also include at least one of an exhaust pipe and a return pipe, both of which are used to connect to the evaporation module 3100. The exhaust pipe is used to lead the gaseous working fluid out of the evaporation module 3100, while the return pipe is used to guide the liquid working fluid generated by condensation into the evaporation module 3100.

[0052] In practical applications, to ensure that the heat source component 2000 achieves good phase change heat transfer at each mating region 3112A, the liquid working fluid in the evaporation chamber 3111 should cover each mating region 3112A as much as possible. This allows the heat source component 2000 to effectively transfer heat to the liquid working fluid at each mating region 3112A, promoting boiling and evaporation of the liquid working fluid, thus better cooling the heat source component 2000. Therefore, during normal use, the evaporation chamber 3111 is filled with a relatively sufficient amount of liquid working fluid, ensuring that the liquid level in the evaporation chamber 3111 is higher than that in each mating region 3112A.

[0053] Please refer to Figure 6 and Figure 7 , Figure 6This is a diagram showing the internal structure of the evaporation module of a phase change heat exchanger in the related technology when it is not tilted. Figure 7 This is a diagram showing the internal structure of the evaporation module in a phase change heat exchanger when it is tilted. It should be noted that... Figure 6 and Figure 7 The reference numerals in the accompanying drawings have been augmented with the symbol “′” to indicate that the corresponding structure belongs to a solution in the related art, and is not a structure of the embodiment of this application.

[0054] In related technologies, such as Figure 6 As shown, when the evaporation module 3100′ is in the predetermined installation posture, the third direction Z can be basically parallel to the direction of gravity. At this time, the liquid working fluid in the evaporation chamber 3111′ can be distributed in the lower part of the evaporation chamber 3111′ under the action of gravity, and can cover each mating area 3112A′.

[0055] However, as Figure 7 As shown, when the evaporation module 3100′ is tilted relative to the predetermined installation posture, the third direction Z and the direction of gravity will form an angle. At this time, the liquid working medium in the evaporation chamber 3111′ can accumulate in the relatively lower part of the second direction Y under the action of gravity, resulting in a relatively less liquid working medium in the relatively higher part of the second direction Y. For example, refer to Figure 7 The orientation and positional relationship within the evaporation module 3100′ are such that when the left side is tilted downward and the right side is tilted upward, the liquid working fluid will accumulate on the left side of the evaporation chamber 3111′. This will result in the mating area 3112A′ located on the right side not receiving sufficient liquid working fluid coverage, which will affect the evaporation heat absorption performance of the evaporation module 3100′. Consequently, it may cause overheating of some heat source components inside the electrical equipment, seriously affecting the normal use of the electrical equipment.

[0056] The tilting of the evaporator module 3100' can be caused by a variety of reasons. For example, misalignment of the mounting surface of the electrical equipment, insufficient installation precision, or vibration during use can all cause the evaporator module 3100' to deviate from its intended installation posture. Furthermore, in aquatic environments, such as at sea, the electrical equipment itself may experience periodic oscillations due to wave surges, causing the evaporator module 3100' to tilt periodically, making it difficult to maintain its intended installation posture.

[0057] To address this, this application provides a novel evaporation module 3100. By setting a blocking structure within the evaporation chamber 3111 of the evaporation module 3100, the blocking structure can form a liquid-retaining zone within the evaporation chamber, thereby intercepting and retaining the liquid working fluid. This restricts the overall flow of the liquid working fluid along the second direction Y under gravity, ensuring that different mating areas 3112A are well covered by the liquid working fluid. This improves the evaporation heat absorption performance of the evaporation module 3100, reducing the possibility of overheating problems in the internal heat source components of electrical equipment and helping to ensure the normal operation of the electrical equipment.

[0058] Please refer to Figures 8-11 , Figure 8 This is a diagram showing the internal structure of the first evaporation module provided in this application embodiment when it is not tilted. Figure 9 for Figure 8 A cross-sectional view of the evaporation module perpendicular to the second direction. Figure 10 for Figure 8 Internal structure diagram of the evaporation module when tilted. Figure 11 for Figure 10 Internal structural diagram of a modified design of the evaporation module.

[0059] In the embodiments of this application, such as Figure 8 and Figure 9 As shown, the blocking structure 3120 includes at least one blocking portion 3121, which can be connected to the first wall panel 3112 and the second wall panel 3113. In specific manufacturing, the blocking portion 3121 can be manufactured separately and then connected to the first wall panel 3112 and the second wall panel 3113 by welding or other means; or, at least one of the first wall panel 3112 and the second wall panel 3113 can be the blocking portion 3121 connected by integral molding.

[0060] The blocking part 3121 can define a liquid-retaining region 3111A within the evaporation chamber 3111. There can be one liquid-retaining region 3111A. Alternatively, there can be multiple liquid-retaining regions 3111A, in which case each liquid-retaining region 3111A can be arranged along the second direction Y. The liquid-retaining region 3111A is used to contain the liquid working fluid.

[0061] The projection of the liquid-retaining area 3111A onto the first wall panel 3112 along the first direction X covers at least one mating area 3112A. Here, "covering" means that when viewed along the first direction X, the projected outline of the liquid-retaining area 3111A is completely consistent with the projected outline of the mating area 3112A, or the projected outline of the liquid-retaining area 3111A is larger than the projected outline of the mating area 3112A, so that the liquid-retaining area 3111A can completely cover the mating area 3112A.

[0062] In the implementation shown in the diagram, such as Figure 8 and Figure 10 As shown, a liquid-retaining area 3111A can cover a mating area 3112A. In addition, in some other implementations of this application, a liquid-retaining area 3111A can also simultaneously cover multiple mating areas 3112A adjacently disposed along the second direction Y.

[0063] like Figure 8 As shown, when the evaporation module 3100 is not tilted, it can be in a predetermined installation posture, with the third direction Z basically parallel to the direction of gravity. The liquid working fluid can cover each mating area 3112A to ensure the evaporation heat absorption performance of the evaporation module 3100.

[0064] like Figure 10 As shown, when the evaporation module 3100 tilts relative to the predetermined installation posture along the second direction Y, the direction of gravity and the third direction Z will form an angle, and the liquid working fluid in the evaporation chamber 3111 will flow to the relatively lower side of the evaporation chamber 3111. However, due to the setting of the blocking part 3121 and the liquid retention area 3111A, part of the liquid working fluid will be intercepted in the liquid retention area 3111A, instead of all flowing to the relatively lower side of the evaporation chamber 3111. This allows the mating area 3112A, whose projection along the first direction X is covered by the liquid retention area 3111A, to still receive a relatively large amount of liquid working fluid for use, thereby improving the overall evaporation heat absorption performance of the evaporation module 3100 in the tilted posture.

[0065] Furthermore, the connection between the blocking portion 3121 and the first wall plate 3112 and the second wall plate 3113 helps to improve the structural strength of the evaporation shell 3110, reducing the risk of deformation such as bulging or collapse of the surface of the evaporation shell 3110. In addition, the setting of the blocking portion 3121 can also increase the contact area between the interior of the evaporation module 3100 and the liquid working fluid, that is, it can increase the effective evaporation area inside the evaporation module 3100, which is also of relatively positive significance for improving the evaporation heat absorption performance of the evaporation module 3100.

[0066] Here, the embodiments of this application do not limit the number of liquid-retaining areas 3111A. In practical applications, those skilled in the art can set the number according to specific needs. For example, each mating region 3112A can be provided with a corresponding liquid-retaining area 3111A. Such a solution can be found in [reference needed]. Figure 8 and Figure 10When tilting occurs, each liquid-holding zone 3111A can intercept a portion of the liquid working fluid to supply the corresponding mating zone 3112A for boiling evaporation. Alternatively, a liquid-holding zone 3111A can be set up specifically for mating zones 3112A that are prone to liquid shortage during tilting, while other mating zones 3112A can be exempted from liquid-holding zones 3111A. This simplifies the internal structure of the evaporation module 3100, and this implementation will be explained in detail later.

[0067] In other implementations of this application, only one of the first wall plate 3112 and the second wall plate 3113 may be connected to the blocking part 3121 to achieve installation and fixation of the blocking part 3121. This also increases the area of ​​the internal solid structure of the evaporation chamber 3111, increasing the contact area with the liquid working fluid, thereby increasing the effective evaporation area of ​​the evaporation module 3100 and improving its evaporation heat absorption performance. As for the other of the first wall plate 3112 and the second wall plate 3113, it may have a preset gap with the blocking part 3121 along the first direction X. The specific size of this preset gap is not limited here; in practical applications, those skilled in the art can select it according to specific needs, as long as it meets the requirements of use. It should be noted that the preset gap should not be too large, as an excessively large gap will affect the interception effect of the liquid-retaining zone 3111A on the liquid working fluid.

[0068] In some implementation methods, combined Figure 8 and Figure 10 The liquid-retaining area 3111A can be generally U-shaped, having two side boundary stops 3111A3 and a bottom boundary stop 3111A4, at least a portion of the side boundary stops 3111A3 and the bottom boundary stop 3111A4 being formed by a blocking portion 3121.

[0069] Specifically, the side boundary stops 3111A3 can be spaced apart along the second direction Y to define the two boundaries of the liquid-retaining zone 3111A along the second direction Y; the bottom boundary stop 3111A4 can be located below the liquid-retaining zone 3111A along the third direction Z to define the bottom boundary of the liquid-retaining zone 3111A along the third direction Z. Both the side boundary stops 3111A3 and the bottom boundary stops 3111A4 can block the liquid working fluid, thereby intercepting the liquid working fluid when the evaporation module 3100 tilts.

[0070] The liquid retention area 3111A also has an inlet / outlet 3111A5, which is located on the side of the liquid retention area 3111A away from the bottom boundary stop 3111A4 along the third direction Z. The liquid retention area 3111A is connected to other areas within the evaporation chamber 3111 through the inlet / outlet 3111A5. In this way, when the evaporation module 3100 swings back from the tilted position to the predetermined installation position, the liquid working fluid in other areas can flow into the liquid retention area 3111A through the inlet / outlet 3111A5 to quickly replenish the liquid in the liquid retention area 3111A.

[0071] In some implementations, such as Figures 8-10 As shown, the blocking part 3121 can extend approximately along the third direction Z and connect with the bottom wall plate 3115, which can form the bottom boundary stop 3111A4 of each liquid retention area 3111A.

[0072] In this implementation, in a cross section perpendicular to the first direction X, the blocking part 3121 itself cannot independently form a liquid-retaining zone 3111A. The main function of the blocking part 3121 is to separate and define at least two liquid-retaining zones 3111A within the evaporation chamber 3111. The blocking part 3121 is located between two adjacent liquid-retaining zones 3111A and can form a side boundary stop 3111A3 shared by the two adjacent liquid-retaining zones 3111A, which is used to prevent the bottoms of the two adjacent liquid-retaining zones 3111A from connecting, thereby enhancing the interception capacity of each liquid-retaining zone 3111A for the liquid working fluid.

[0073] There may be one or more blocking parts 3121, which is not limited here.

[0074] by Figure 8 and Figure 10Taking the scheme in the example, the number of blocking parts 3121 can be two, and the two blocking parts 3121 are arranged at intervals along the second direction Y to separate three liquid retention zones 3111A within the evaporation chamber 3111. In a cross section perpendicular to the first direction X, the leftmost liquid retention zone 3111A is formed by a left side wall plate 3117, a bottom wall plate 3115, and a blocking part 3121. For this liquid retention zone 3111A, the left side wall plate 3117 and the blocking part 3121 can respectively form two side boundary stops 3111A3, and the bottom wall plate 3115 can form a bottom boundary stop 3111A4; the middle liquid retention zone 3111A is formed by two blocking parts 3121 and the bottom wall plate 3115. In case of A, the two blocking parts 3121 can respectively form two side boundary stops 3111A3, and the bottom wall plate 3115 can form a bottom boundary stop 3111A4; the rightmost liquid-retaining area 3111A is formed by the right side wall plate 3117, the bottom wall plate 3115 and a blocking part 3121. For this liquid-retaining area 3111A, the right side wall plate 3117 and the blocking part 3121 can respectively form two side boundary stops 3111A3, and the bottom wall plate 3115 can form a bottom boundary stop 3111A4.

[0075] Reference Figure 10 The orientation and positional relationship in the evaporation module 3100, such as Figure 10 When the evaporation module 3100 tilts to the left, the liquid working fluid in the evaporation chamber 3111 will spontaneously flow to the left. However, the liquid retention zone 3111A on the far right can intercept the flow of liquid working fluid, ensuring that it still contains a certain amount of liquid working fluid. This allows the relatively higher rightmost mating region 3112A to also obtain relatively good evaporation heat transfer conditions. Similarly, when the evaporation module 3100 tilts to the right, the liquid working fluid in the evaporation chamber 3111 will spontaneously flow to the right. However, the liquid retention zone 3111A on the far left can intercept the flow of liquid working fluid, ensuring that it still contains a certain amount of liquid working fluid. This allows the relatively higher leftmost mating region 3112A to also obtain relatively good evaporation heat transfer conditions.

[0076] In some implementations, at least a portion of the side boundary stop 3111A3 is provided with a protrusion 3121A extending in a second direction at one end away from the bottom boundary stop 3111A4, and the protrusion 3121A is located on the side of the side boundary stop 3111A3 facing the liquid retention area 3111A.

[0077] The protrusion 3121A increases the path that the liquid working fluid needs to take to cross the side boundary stop 3111A3 when tilting occurs, thereby enhancing the blocking effect of the side boundary stop 3111A3 and the interception and liquid retention capacity of the liquid retention area 3111A. This allows the liquid level of the liquid working fluid in the liquid retention area 3111A to be raised, so as to better cover the mating area 3112A, thereby enabling reliable heat exchange between the mating area 3112A and the heat source component 2000.

[0078] In addition, when the evaporation module 3100 swings back from its tilted position to the predetermined installation position, the aforementioned protrusion 3121A can reduce the inertial overflow of the liquid working fluid in the liquid retention area 3111A, which was originally in a lower position under the tilted position, thereby reducing the risk of liquid shortage inside the liquid retention area 3111A.

[0079] It is evident that, whether tilting or swinging occurs, the aforementioned protrusion 3121A allows more liquid working fluid to be trapped within the corresponding liquid retention zone 3111A, thereby significantly improving the liquid retention capacity of the liquid retention zone 3111A and enabling a relatively high liquid level within the liquid retention zone 3111A.

[0080] Here, the specific shape of the protrusion 3121A is not limited in this embodiment. In practical applications, those skilled in the art can choose according to specific needs, as long as it meets the requirements of use. For example, if a cross-section is made along the first direction X perpendicular to the protrusion 3121A, the shape of the resulting cross-section can be a triangle, rectangle, trapezoid, semicircle, or other shapes, etc.

[0081] In one exemplary solution, such as Figure 11 As shown, in the aforementioned technical solution where the blocking part 3121 is located between two adjacent liquid retention areas 3111A and the blocking part 3121 forms a side boundary stop 3111A3 shared by the two adjacent liquid retention areas 3111A, the protrusion 3121A can be provided at one end of the blocking part 3121 away from the bottom wall plate 3115.

[0082] In this design, for the rightmost liquid-retaining zone 3111A, without the protrusion, the liquid level can reach position S′. However, with the protrusion 3121A, the liquid level can rise to position S, significantly increasing its height. For the leftmost liquid-retaining zone 3111A, a large amount of liquid working fluid accumulates inside when tilted. If the evaporation module swings back, a large amount of liquid working fluid in the leftmost liquid-retaining zone may overflow due to inertia. By providing the protrusion 3121A, this inertial overflow can be mitigated, ensuring that a relatively large amount of liquid working fluid remains in the leftmost liquid-retaining zone 3111A even during a swing.

[0083] In some implementations, such as Figure 8 As shown, the end of the blocking part 3121 away from the bottom wall plate 3115 and the top wall plate 3114 may have a flow gap 3116. The flow gap 3116 allows the upper space of the adjacent liquid retention area 3111A to remain connected, thereby achieving the technical objective of connecting the liquid retention area 3111A to other areas in the evaporation chamber 3111 through the inlet and outlet 3111A5.

[0084] With this configuration, the gaseous working fluid produced by the evaporation of the liquid working fluid in one liquid-holding zone 3111A can not only flow in the space above that liquid-holding zone 3111A, but also flow to the space above other liquid-holding zones 3111A. This allows for a more uniform distribution of the gaseous working fluid within the evaporation chamber 3111, facilitating its distribution to each condensation chamber 3211 and significantly reducing the problem of insufficient gaseous working fluid distribution in individual condensation units 3210. In other words, it improves the uniformity of gaseous working fluid distribution within each condensation unit 3210.

[0085] Furthermore, when the evaporation module 3100 rotates from an inclined position to a predetermined installation position, the aforementioned flow gap 3116 facilitates the rapid return and replenishment of liquid working fluid to each liquid retention zone 3111A. Specifically, as... Figure 8 As shown, in the predetermined installation posture, the liquid level of the working fluid must be higher than the upper surface of the blocking part 3121; as Figure 10 As shown, in the tilted posture, despite the obstruction of the blocking part 3121 and the interception and liquid retention of the liquid retention area 3111A, the amount of liquid working fluid in the liquid retention area 3111A at a relatively high position (e.g., the rightmost liquid retention area 3111A) is still relatively small, while the amount of liquid working fluid at the location of the liquid retention area 3111A at a relatively low position (e.g., the leftmost liquid retention area 3111A) is still relatively large; in the evaporation module 3100 from Figure 10 The tilted attitude shown Figure 8 When the predetermined installation posture is swung back, due to the presence of the flow gap 3116, the liquid working fluid that originally accumulated on the left side of the evaporation chamber 3111 can be quickly returned to the liquid retention area 3111A in other locations for replenishment.

[0086] Here, the embodiments of this application do not limit the dimensions of the blocking part 3121 and the flow gap 3116 along the third direction Z. In practical applications, those skilled in the art can select them according to specific needs, as long as the requirements of use are met. It should be understood that the larger the dimension of the blocking part 3121 along the third direction Z, the stronger the interception capacity of the formed liquid retention area 3111A; the larger the dimension of the flow gap 3116 along the third direction Z, the stronger the flow capacity of the gaseous working fluid above each liquid retention area 3111A, and the stronger the liquid return and replenishment capacity of the evaporation module 3100 when switching from the tilted posture to the predetermined installation posture.

[0087] It should be understood that in some other implementations of the embodiments of this application, the blocking part 3121 may also be connected to the top wall plate 3114 to better improve the mechanical strength of the evaporation shell 3110. In this implementation, the liquid-retaining areas 3111A on both sides of the blocking part 3121 can be completely isolated within the evaporation chamber 3111. Alternatively, if it is required that the liquid-retaining areas 3111A on both sides of the blocking part 3121 remain in a connected state within the evaporation chamber 3111, this can be achieved by providing an opening at the end of the blocking part 3121 near the top wall plate 3114. The shape and number of the openings are not limited.

[0088] Please refer to Figure 12 and Figure 13 , Figure 12 This is a diagram showing the internal structure of the second type of evaporation module provided in this application embodiment when it is tilted. Figure 13 for Figure 12 Internal structural diagram of a modified design of the evaporation module.

[0089] In some implementations, such as Figure 12 As shown, the blocking part 3121 includes a bottom plate 3121B and two side plates 3121C.

[0090] Two side plates 3121C are spaced apart along the second direction Y. A bottom plate 3121B is connected to the two side plates 3121C and is located at the lower end of the two side plates 3121C along the direction of gravity. The blocking part 3121 is formed as a groove-shaped structure open to one side. In a cross-section perpendicular to the first direction X, the blocking part 3121 is approximately U-shaped. The bottom plate 3121B and the two side plates 3121C together enclose the liquid retention area 3111A. In this implementation, the bottom plate 3121B can form a bottom boundary stop 3111A4 of the liquid retention area 3111A to prevent the liquid working medium from flowing downwards out of the liquid retention area 3111A along the direction of gravity. The two side plates 3121C can form side boundary stops 3111A3 of the liquid retention area 3111A to prevent the liquid working medium from flowing out of the liquid retention area 3111A along the second direction Y.

[0091] In a cross section perpendicular to the first direction X, the liquid retention area 3111A is formed by the barrier portion 3121 itself, without the participation of the bottom wall plate 3115 and the side wall plate 3117. The liquid retention area 3111A is only formed in the area near the mating area 3112A. There is still a large external space outside the barrier portion 3121 in the evaporation chamber 3111 where the liquid working fluid can flow.

[0092] With this configuration, when the evaporation module 3100 tilts or swings back, the liquid working fluid can still flow back and forth in the external space. This enhances the flow mixing and heat exchange between different areas of the liquid working fluid in the evaporation chamber 3111. It allows the relatively low-temperature liquid working fluid to flow to the area where the heat source component 2000 with higher heat generation is located, and allows the liquid working fluid that has absorbed more heat in that area to migrate to other areas. This reduces the temperature difference between different areas of the liquid working fluid, which is of relatively positive significance for suppressing local heat accumulation, improving the temperature uniformity of the evaporation module 3100, and reducing dry burning.

[0093] In this implementation, the number of blocking parts 3121 can be the same as the number of liquid-retaining areas 3111A. Both can be set to one or more, and no limitation is made here.

[0094] In some implementations, such as Figure 13 As shown, at least one of the bottom plate 3121B and the two side plates 3121C may be provided with an opening 3121D. That is, the opening 3121D may be provided only in the side plate 3121C, or only in the bottom plate 3121B, or both the bottom plate 3121B and the side plates 3121C may have openings 3121D. The opening 3121D can connect the liquid-retaining area 3111A and the external space.

[0095] With this approach, when the liquid working fluid in the liquid storage zone 3111A decreases due to continuous evaporation, the liquid working fluid in the external space can enter the liquid storage zone 3111A through the opening 3121D to replenish the liquid in the liquid storage zone 3111A. This can largely prevent the liquid storage zone 3111A from running dry due to lack of liquid, which is beneficial to improving the evaporation heat absorption performance of the evaporation module 3100.

[0096] Here, the embodiments of this application do not limit the number and flow area of ​​the openings 3121D. In practical applications, those skilled in the art can select according to specific needs, as long as the requirements of use are met. For example, the flow area of ​​the opening 3121D should not be too large, so as to prevent the liquid working medium in the liquid retention area 3111A from flowing out completely in a short time during the process of swinging from a lower position to a higher position. For usage scenarios with periodic swinging, such as in aquatic environments, the swinging period can be calculated, and then the flow area of ​​the openings 3121D can be adjusted according to the swinging period, the number of openings 3121D, and other relevant parameters.

[0097] In an implementation with multiple blocking portions 3121, all blocking portions 3121 may be provided with the aforementioned opening 3121D, or only some blocking portions 3121 may be provided with the aforementioned opening 3121D. For example, see... Figure 13 For the three blocking parts 3121 in the attached figure, openings 3121D can be provided only in the blocking parts 3121 located on both sides.

[0098] Please refer to Figure 14 and Figure 15 , Figure 14 This is a diagram showing the internal structure of the third evaporation module provided in this application embodiment when it is tilted. Figure 15 for Figure 14 A magnified view of the middle blocking section.

[0099] In some implementations, such as Figure 14 and Figure 15 As shown, the blocking part 3121 includes a baffle plate 3121E and a heat dissipation part 3121F.

[0100] The heat dissipation unit 3121F includes at least three heat dissipation plates 3121F1 spaced apart along the second direction Y. Each heat dissipation plate 3121F1 is connected to the first wall plate 3112 and the second wall plate 3113. The heat generated by the heat source component 2000 is transferred to the heat dissipation unit 3121F via the first wall plate 3112, and can then exchange heat with the liquid working fluid through the multiple heat dissipation plates 3121F1. Compared to the casement area of ​​the first wall plate 3112 contacting the liquid working fluid only, the multiple heat dissipation plates 3121F1 can increase the contact area with the liquid working fluid, thereby increasing the effective evaporation area inside the evaporation module 3100 and improving the evaporation heat absorption performance of the evaporation module 3100.

[0101] A sub-channel 3121F2 is formed between two adjacent heat sinks 3121F1. Multiple sub-channels 3121F2 are arranged along the second direction Y and extend along the third direction Z. In practical applications, the number of heat sinks 3121F1 will be relatively large and the heat sinks 3121F1 will be arranged relatively densely. Therefore, the size of each sub-channel 3121F2 along the second direction Y is relatively small.

[0102] The baffle 3121E is located on one side of the heat dissipation unit 3121F along the third direction Z, and is spaced apart from the heat dissipation unit 3121F along the third direction Z. The heat dissipation plate 3121F1 and the baffle 3121E located at both ends of the heat dissipation unit 3121F along the second direction Y define the liquid retention area 3111A. The liquid retention area 3111A can be roughly referred to as Figure 15 The area circled by the double-dotted line includes all the aforementioned sub-channels 3121F2. Figure 15 In the indicated orientation and positional relationship, the heat dissipation plates 3121F1 located at both ends along the second direction Y in the heat dissipation section 3121F form side boundary stop members 3111A3 of the liquid retention area 3111A, and the baffle plate 3121E is located on the lower side of the heat dissipation section 3121F along the direction of gravity, forming the bottom boundary stop member 3111A4 of the liquid retention area 3111A. The baffle plate 3121E can block the liquid working fluid flowing out from the lower end of the sub-channel 3121F2, making it difficult for the liquid working fluid entering the multiple sub-channels 3121F2 to leave the heat dissipation section 3121F directly along the direction of gravity, thereby intercepting the liquid working fluid when the evaporation module 3100 tilts. At the same time, a gap is maintained between the baffle plate 3121E and the heat dissipation section 3121F, which can prevent the lower end of the sub-channel 3121F2 from being completely closed. In this way, after the liquid working fluid in the sub-channel 3121F2 evaporates to produce gaseous working fluid, the gaseous working fluid can be discharged more smoothly from the upper end of the sub-channel 3121F2, thereby reducing the occurrence of airlock.

[0103] In this implementation, the heat dissipation section 3121F not only participates in forming the liquid retention area 3111A for containing the liquid working fluid, but also serves as an extension structure for the first wall plate 3112 to transfer heat to the liquid working fluid. The multiple heat dissipation plates 3121F1 can increase the effective heat exchange area near the mating area 3112A, so that the heat received by the first wall plate 3112 can be transferred to the liquid working fluid through the multiple heat dissipation plates 3121F1, thereby allowing more liquid working fluid to participate in heat exchange, reducing the situation where heat is concentrated in a local location in the mating area 3112A, and more effectively improving the evaporative heat exchange performance.

[0104] Here, the embodiments of this application do not limit the spacing between two adjacent heat sinks 3121F1 along the second direction Y, or the spacing between the heat sink 3121F1 and the baffle 3121E along the third direction Z. In practical applications, those skilled in the art can make the selection according to specific needs, as long as it can meet the requirements of use.

[0105] It should be understood that the above description of the specific structural form of the blocking part 3121 is merely an exemplary illustration made in conjunction with the accompanying drawings of the embodiments of this application. This should not be construed as limiting the scope of the evaporation module 3100 provided in the embodiments of this application. Under the condition of satisfying the function, the blocking part 3121 can also be configured in other structural forms. For example, the blocking part 3121 can be V-shaped. Another example is that the blocking part 3121 can be annular, and the aforementioned opening 3121D can be provided in the blocking part 3121. Yet another example is that the blocking part 3121 can also be L-shaped. In this case, the blocking part 3121 can be connected to a side wall plate 3117 to cooperate with the side wall plate 3117 to form a liquid-retaining area 3111A.

[0106] Please refer to Figure 16 , Figure 16 This is a simplified diagram of the distribution structure of the blocking part on the first wall panel.

[0107] In some implementations, not all mating areas 3112A may be provided with a corresponding liquid-retaining area 3111A formed by the blocking part 3121.

[0108] Specifically, such as Figure 16 As shown, the first wall panel 3112 can be divided along the second direction Y into a first end region 3112B, a second end region 3112C, and a middle region 3112D. The first end region 3112B and the second end region 3112C are located at the two ends of the first wall panel 3112 along the second direction Y, respectively, and the middle region 3112D is located between the first end region 3112B and the second end region 3112C. At least one mating region 3112A can be provided in each of the first end region 3112B, the second end region 3112C, and the middle region 3112D.

[0109] When the evaporation module 3100 is tilted, the mating region 3112A located in the first end region 3112B and the second end region 3112C is most prone to liquid shortage, while the mating region 3112A located in the middle region 3112D is less likely to experience liquid shortage.

[0110] Thus, a first liquid-retaining region 3111A1 and a second liquid-retaining region 3111A2 can be provided in the evaporation chamber 3111. The first liquid-retaining region 3111A1 and the second liquid-retaining region 3111A2 are respectively located at the two ends of the evaporation chamber 3111 along the second direction Y. The projection of the first liquid-retaining region 3111A1 along the first direction X on the first wall plate 3112 covers the mating region 3112A in the first end region 3112B, and the projection of the second liquid-retaining region 3111A2 along the first direction X on the first wall plate 3112 covers the mating region 3112A in the second end region 3112C.

[0111] When the evaporation module 3100 is tilted, causing the first end region 3112B to be in a relatively low position, the second liquid-retaining region 3111A2 can intercept the liquid working fluid, thereby better meeting the heat exchange requirements of the mating region 3112A of the second end region 3112C. When the evaporation module 3100 is tilted, causing the second end region 3112C to be in a relatively low position, the first liquid-retaining region 3111A1 can intercept the liquid working fluid, thereby better meeting the heat exchange requirements of the mating region 3112A of the first end region 3112B.

[0112] As for the central region 3112D, it can omit the blocking part 3121, thus reducing the number of blocking parts 3121, simplifying the internal structure of the evaporation module 3100, and lowering the manufacturing difficulty. Of course, if necessary, the central region 3112D can also be provided with one or more liquid-retaining zones 3111A.

[0113] The above implementations show various forms of blocking parts 3121. For an evaporation module 3100, the blocking parts 3121 provided inside it can be completely identical or different. This application embodiment does not limit this.

[0114] Furthermore, the improvement of this application embodiment focuses on the evaporation module 3100. Therefore, the aforementioned implementation methods mainly limit the relevant structure of the evaporation module 3100, while the condensation module 3200 is not basically limited. In practical applications, the evaporation module 3100 involved in this application embodiment can be used in conjunction with any form of condensation module 3200 in related technologies.

[0115] The above are merely optional embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
