TECHNICAL FIELD
[0001] The present disclosure belongs to the technical field of heat dissipation devices, and particularly relates to a heat siphon heat dissipation device. BACKGROUND
[0002] In the heat siphon heat dissipation device in the related art, the working medium evaporated by the evaporator directly flows to the condenser through the steam pipe, and the working medium is condensed by the condenser and then flows back to the evaporator. Since the working medium flowing from the evaporator to the condenser is not an ideal completely vaporized working medium with a dryness of 100%, but a vapor-liquid mixed working medium, the so-called dryness refers to the proportion of the mass of the vapor state working medium in the mass of the vapor-liquid mixed working medium. In most cases, the dryness of the vapor-liquid mixed working medium when the working medium enters the condenser through the steam pipe is less than 50%, and the smaller the dryness, the lower the cooling efficiency of the condenser (because only the vapor state part has the heat release function of condensing and liquefying), and therefore, there is an urgent need to improve the existing heat siphon heat dissipation device to improve the cooling efficiency of the condenser and the heat dissipation efficiency of the heat siphon heat dissipation device.

[0062] Example implementations are now described with reference to the drawings; however, these descriptions are not intended to limit the scope of the application, but are intended to provide example examples, which, while possibly being the best modes of practicing the application at the time, were developed for purposes of illustration.
[0063] Additionally, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the application. One skilled in the relevant art will recognize, however, that the
[0064] The application is further described below with reference to the drawings and specific examples. It is to be understood that the specific examples described below are merely exemplary and that the application is not limited to the specific examples described below. In the following description, numerous specific details are provided to give a thorough understanding of the application. One skilled in the relevant art will recognize, however, that the application can be practiced without one or more of the specific details, or with other methods, components, materials, and so forth. In other instances, well-known methods, devices, and so forth are not shown or described in detail to avoid obscuring aspects of the application.
[0065] As Figure 1 shown in the prior art, the thermosyphon heat dissipation device mainly consists of an evaporator 1, a condenser 2, a steam pipe 3 and a liquid return pipe 41. The evaporator 1 is located at the lower part of the condenser 2, and is used to guide the working medium vaporized in the evaporator 1 into the condenser 2. In the thermosyphon heat dissipation device, the working medium directly guided by the evaporator 1 into the condenser 2 through the steam pipe 3 is in a vapor-liquid mixed state, and in most cases, the dryness of the vapor-liquid mixed state working medium is less than 50%. The smaller the dryness of the working medium entering the condenser 2, the lower the condensation efficiency of the condenser 2, and in turn, the poorer the overall heat dissipation effect of the thermosyphon heat dissipation device.
[0066] To solve the above technical problems, as Figure 2As shown, the present disclosure provides a thermosyphon heat dissipation device, which can include a condenser 2, an evaporator 1 and a gas-liquid separator.
[0067] The condenser 2 can include a condensing body part 21, and an inlet structure and an outlet structure in communication with the condensing body part 21. The condensing body part 21 is configured to condense the working medium vaporized in the evaporator 1, the inlet structure can be configured to guide the working medium vaporized in the evaporator 1 into the condensing body part 21, and the outlet structure can be configured to return the liquid working medium condensed by the condensing body part 21 to the evaporator 1.
[0068] The evaporator 1 can include an evaporating body part 11, and a liquid inlet 13 and a gas outlet 12 in communication with the evaporating body part 11. The gas outlet 12 is in communication with the inlet structure, and the liquid inlet 13 is in communication with the outlet structure. The liquid working medium in the evaporating body part 11 is vaporized, then enters the condensing body part 21 in sequence through the gas outlet 12 and the inlet structure, and is condensed by the condensing body part 21, then returns to the evaporating body part 11 in sequence through the outlet structure and the liquid inlet 13.
[0069] The gas-liquid separator can at least include a liquid collecting pipe 51, a first end of the liquid collecting pipe 51 can be in communication with the gas outlet 12 and the inlet structure, and a second end of the liquid collecting pipe 51 can be in communication with the liquid inlet 13. The liquid collecting pipe 51 can allow at least part of the liquid working medium in the working medium flowing out of the gas outlet 12 to return to the evaporating body part 11 through the liquid inlet 13, and the working medium not recovered by the liquid collecting pipe 51 flows into the condensing body part 21 through the inlet structure to achieve heat dissipation and condensation.
[0070] That is, the embodiment of the present disclosure sets the liquid collecting pipe 51 in communication with the inlet structure and the gas outlet 12, so that while the working medium vaporized in the evaporating body part 11 is transported to the condenser 2, at least part of the liquid working medium in the working medium obtained from the gas outlet 12 can also be recovered by the liquid collecting pipe 51, reducing the liquid working medium entering the condensing body part 21 through the inlet structure, improving the dryness of the working medium entering the condensing body part 21, and thus improving the cooling efficiency of the condenser 2 and the heat dissipation efficiency of the entire thermosyphon heat dissipation device.
[0071] In some embodiments, the gas-liquid separator can include a first pipe 61, a first end of the first pipe 61 can be in communication with the gas outlet 12, and a second end of the first pipe 61 can be in communication with the inlet structure. The first end of the liquid collecting pipe 51 can be located on the flow path between the gas outlet 12 and the inlet structure, and can be in communication with the first pipe 61. The working medium flowing from the evaporating body part 11 to the gas-liquid separator through the gas outlet 12 is subjected to gas-liquid separation under the action of gravity, at least part of the liquid working medium separated in the gas-liquid separator can be recovered to the evaporator 1 through the liquid collecting pipe 51, and at least part of the gaseous working medium separated in the gas-liquid separator can flow to the condensing body part 21 in sequence through the first pipe 61 and the inlet structure.
[0072] In some embodiments, the gas-liquid separator can simultaneously include the first pipe 61 and an adapter 52, the adapter 52 being hollow inside, the adapter 52 can include a first interface, a second interface and a liquid collection interface in communication with the inside thereof, the first interface being in communication with the gas outlet 12, the second interface being in communication with the inlet structure, the liquid collection interface being lower than the first interface and the second interface in the vertical direction Z, and the liquid collection interface being in communication with the first end of the liquid collection pipe 51. At this time, the first end of the first pipe 61 can be in communication with the second interface, and the second end of the first pipe 61 can be in communication with the inlet structure, that is, the adapter 52 can be in communication with the inlet structure through the first pipe 61.
[0073] For example, the liquid collection interface in the embodiment of the present disclosure can be arranged at the bottom of the adapter 52, so as to collect the separated liquid working medium in the working medium. In the embodiment of the present disclosure, the working medium in the adapter 52 separates the liquid working medium under the action of gravity, the liquid working medium drops to the bottom of the adapter 52, and then flows back to the evaporation main body part 11 through the liquid collection interface at the bottom of the adapter 52, the liquid collection pipe 51 and the liquid inlet 13.
[0074] Further, as shown in Figure 3 The gas-liquid separator can further include a first joint 53, a second joint 54 and a third joint 55.
[0075] Specifically, the first end of the first joint 53 can be in communication with the first interface, and the second end of the first joint 53 can be in communication with the gas outlet 12, so as to realize the connection and sealing between the adapter 52 and the gas outlet 12.
[0076] For example, the gas-liquid separator can further include a second pipe 62, the first end of the second pipe 62 can be in communication with the gas outlet 12, and the second end of the second pipe 62 can be in communication with the second end of the first joint 53. Wherein, the second end of the first joint 53 can be sleeved on part of the outer periphery of the second pipe 62, so as to realize the assembly and sealing between the second pipe 62 and the adapter 52.
[0077] In the embodiment of the present disclosure, the cross-sectional area inside the adapter 52 can be greater than or equal to the cross-sectional area inside the second pipe 62, so as to ensure that there is a large enough cross section inside the adapter 52 to realize the gas-liquid separation of the working medium, to ensure that the liquid working medium in the working medium effectively settles, and to reduce the carrying capacity of the vapor working medium to the liquid working medium.
[0078] The first end of the second joint 54 can be in communication with the second interface, and the second end of the second joint 54 can be in communication with the inlet structure.
[0079] For example, the second end of the second joint 54 can be sleeved on a part of the outer periphery of the first pipe 61, so as to facilitate the disassembly and sealing between the first pipe 61 and the adapter 52.
[0080] The first end of the third joint 55 can be in communication with the liquid receiving interface, and the second end of the third joint 55 can be in communication with the first end of the liquid receiving pipe 51.
[0081] For example, the second end of the third joint 55 can be sleeved on a part of the outer periphery of the liquid receiving pipe 51, so as to facilitate the disassembly and sealing between the liquid receiving pipe 51 and the adapter 52.
[0082] However, the gas-liquid separator can also not include the first joint 53, the second joint 54 and the third joint 55, at this time, the gas outlet 12 can be directly connected with the first interface on the adapter 52, the inlet structure can be directly connected with the second interface on the adapter 52, and the first end of the liquid receiving pipe 51 can be directly connected with the liquid receiving interface on the adapter 52, thereby reducing the manufacturing cost of the gas-liquid separator.
[0083] As shown in Figure 3 In some embodiments, the adapter 52 can include a main pipe 56, the main pipe 56 can extend in the horizontal direction X, the first interface, the second interface and the liquid receiving interface can be arranged on the main pipe 56, the first interface and the second interface can be arranged at a distance from each other, and the axis of the liquid receiving interface can extend in the vertical direction Z.
[0084] The liquid receiving interface can be located between the first interface and the second interface, but is not limited thereto, the liquid receiving interface can also be located on the side away from the second interface of the first interface, or the liquid receiving interface can also be located on the side away from the first interface of the second interface, which can be determined according to actual conditions.
[0085] In the embodiments of the present disclosure, the opposite ends of the main pipe 56 in the extension direction can be sealed ends, at this time, the axes of the first joint 53 and the second joint 54 deviate from the axis of the main pipe 56, so that the working medium entering the main pipe 56 from the gas outlet 12 can rotate and flow inside the main pipe 56, and the centrifugal force generated by the rotation of the working medium can be more conducive to the gas-liquid separation of the working medium.
[0086] For example, the opposite ends of the main pipe 56 in the extension direction can be sealed by end covers 71.
[0087] Further, the axes of the first joint 53 and the second joint 54 in the embodiments of the present disclosure can deviate upward from the axis of the main pipe 56 along the vertical direction Z.
[0088] For example, the first interface and the second interface can be arranged at the top of the main pipe 56, and in this case, the first interface and the second interface can be arranged at the highest position of the main pipe 56 in the vertical direction Z, and the axes of the first joint 53 and the second joint 54 can extend along the vertical direction Z, so as to facilitate the gaseous working medium to enter the inlet structure through the second interface.
[0089] In addition, the first interface and the second interface can also be arranged at opposite ends of the main pipe 56 in the extension direction, that is, the first interface and the second interface are arranged on the side wall of the main pipe 56 and are located at opposite ends of the main pipe 56 in the extension direction, so as to lengthen the flow path inside the main pipe 56, lengthen the gas-liquid separation time of the working medium in the main pipe 56, and thus reduce the liquid working medium entering the inlet structure and improve the cooling efficiency of the condenser 2.
[0090] It should be noted that, in addition to arranging the first interface and the second interface on the main pipe 56, the first interface and the second interface can also be arranged on opposite sides of the main pipe 56 in the extension direction of the main pipe 56. Specifically, the end cover 71 in Figure 3 may be removed to arrange the first interface and the second interface on the side of the end cover 71 in Figure 3 . In this case, the first interface can be arranged towards the second interface.
[0091] In some embodiments, the extension direction of the main pipe 56 can form a specific angle with the horizontal direction X, and the specific angle is greater than 0 and less than 180°, so that the flow path inside the main pipe 56 can be arranged obliquely relative to the horizontal direction X, and thus the gas-liquid separation of the working medium inside the main pipe 56 under the action of gravity can be facilitated, so as to improve the dryness of the working medium entering the condenser 2.
[0092] The top end of the main pipe 56 is a sealed end, and the bottom end of the main pipe 56 forms a liquid collecting interface. Along the extension direction of the main pipe 56, the second interface can be located on the side away from the liquid collecting interface of the first interface, so as to lengthen the distance between the outlet end and the inlet end, lengthen the gas-liquid separation time of the working medium in the adapter 52, reduce the liquid working medium entering the inlet structure through the outlet end, improve the dryness of the working medium entering the condensing main body 21, improve the cooling efficiency of the condenser 2, and thus improve the overall heat dissipation efficiency of the thermosyphon heat dissipation device.
[0093] For example, as shown in Figure 4 , the main pipe 56 can extend along the vertical direction Z, so that the working medium entering the inside of the adapter 52 can be subjected to gas-liquid separation under the action of gravity. The top end of the main pipe 56 can be sealed by the end cover 71.
[0094] In the embodiment of the present disclosure, the first interface and the second interface can be arranged in the upper middle part of the adapter 52 in the vertical direction Z to extend the distance between the liquid outlet and the first interface and the second interface, thereby improving the problem of the gaseous working medium directly flowing back to the evaporation main body 11 through the liquid outlet, and thus improving the heat dissipation effect of the thermal siphon heat dissipation device.
[0095] In the embodiment of the present disclosure, the outlet end and the inlet end can be set at opposite ends of the side periphery of the adapter 52 in the horizontal direction X, but is not limited to this. The inlet end and the outlet end can also be set on the same side of the side periphery of the adapter 52 in the horizontal direction X, and can be set specifically according to actual conditions.
[0096] like Figure 5 and Figure 6 As shown, in some embodiments, the adapter 52 may include a first adapter tube 521 , a first connecting portion 522 , and a second adapter tube 523 .
[0097] The first transfer tube 521 may extend along the horizontal direction X. The first and second interfaces may be provided at opposite ends of the first transfer tube 521 in the extension direction and communicate with the interior of the first transfer tube. In other words, the first and second interfaces may be provided on the side periphery of the first transfer tube 521 and located at opposite ends of the first transfer tube 521 in the extension direction.
[0098] Among them, the axis of the first joint 53 and the second joint 54 can deviate from the axis of the first transfer tube 521, so that the working medium entering the adapter 52 from the gas outlet 12 can rotate and flow inside the first transfer tube 521, and the centrifugal force generated by the rotating flow of the working medium can be more conducive to the gas-liquid separation of the working medium.
[0099] Furthermore, in the embodiment of the present disclosure, the axes of the first joint 53 and the second joint 54 may deviate upwardly from the axis of the first transfer tube 521 along the vertical direction Z.
[0100] For example, the first interface and the second interface can be opened at the top of the first transfer tube 521. In this case, the first interface and the second interface can be set at the highest point of the first transfer tube 521 in the vertical direction Z, and the axes of the first joint 53 and the second joint 54 can extend along the vertical direction Z to facilitate the vapor working medium to enter the inlet structure through the second interface.
[0101] The second transfer tube 523 can extend in the horizontal direction and be arranged in the vertical direction with the first transfer tube 521. The second transfer tube 523 is lower than the first transfer tube 521. The liquid collection interface is provided on the second transfer tube 523 and is connected to the interior of the second transfer tube 523. The axis of the liquid collection interface extends in the vertical direction Z.
[0102] For example, the liquid collecting interface can be arranged at the bottom of the second adapter pipe 523 to facilitate the collection of the separated liquid working medium.
[0103] The opposite ends of the first adapter pipe 521 and the second adapter pipe 523 in the respective extension directions thereof can be sealed ends.
[0104] For example, the opposite ends of the first adapter pipe 521 in the extension direction thereof can be sealed by end caps 71, and the opposite ends of the second adapter pipe 523 in the extension direction thereof can be sealed by end caps 71.
[0105] The axial direction of the first adapter pipe 521 can be parallel to the axial direction of the second adapter pipe 523.
[0106] The first connecting portion 522 is arranged between the first adapter pipe 521 and the second adapter pipe 523, and the first connecting portion 522 is provided with a plurality of through holes arranged in the horizontal direction X at intervals, which can be specifically referred to as shown in Figure 6 The through holes can communicate the first adapter pipe 521 and the second adapter pipe 523.
[0107] In the embodiment of the present disclosure, the first connecting portion 522 can extend along the axial direction of the first adapter pipe 521, and the top surface shape of the first connecting portion 522 can be adapted to the bottom surface shape of the first adapter pipe 521, and the bottom surface shape of the first connecting portion 522 can be adapted to the top surface shape of the second adapter pipe 523.
[0108] For example, when the first adapter pipe 521 and the second adapter pipe 523 are both in the shape of a cylinder, the top surface and the bottom surface of the first connecting portion 522 can be in the shape of an adapted circular arc surface, so as to facilitate the sealed connection of the first connecting portion 522 with the first adapter pipe 521 and the second adapter pipe 523.
[0109] In the embodiment of the present disclosure, the first adapter pipe 521 can obtain working medium from the gas outlet 12 through the first interface, the working medium in the first adapter pipe 521 is subjected to gas-liquid separation, the separated liquid working medium can drip to the bottom of the first adapter pipe 521 under the action of gravity, and flow into the second adapter pipe 523 through the through holes on the first connecting portion 522, the liquid working medium in the second adapter pipe 523 can flow back into the evaporation main body portion 11 through the liquid collecting interface, the liquid collecting pipe 51 and the liquid inlet 13, and the remaining working medium in the first adapter pipe 521 can be transported into the condenser 2 through the second interface.
[0110] It is to be explained that the aperture size of the via on the first connecting portion 522 in the embodiment of the present disclosure can be determined according to actual conditions, so as to effectively allow the liquid working medium in the first adapter pipe 521 to sink into the second adapter pipe 523, while effectively improving the problem that the liquid working medium is entrained by the airflow into the condenser 2. That is, the embodiment of the present disclosure can set up controlled intercommunication by adjusting the size and number of the via, so as to improve the vapor-liquid separation effect of the working medium in the adapter 52.
[0111] In some embodiments, the cross-sectional area inside the adapter 52 can be not less than the cross-sectional area inside the first pipeline 61, so as to prolong the residence time of the working medium inside the adapter 52 and enhance the vapor-liquid separation effect of the working medium. However, the cross-sectional area inside the first pipeline 61 can also be greater than the cross-sectional area inside the adapter 52, which can be set according to actual conditions.
[0112] In some embodiments, a baffle 72 can be arranged inside the adapter 52, and the cross-sectional area of the baffle 72 is less than the cross-sectional area inside the adapter 52. When the working medium flows inside the adapter 52, the residence time of the working medium inside the adapter 52 can be prolonged by the baffle 72, so as to prolong the vapor-liquid separation time of the working medium inside the adapter 52, improve the dryness of the working medium entering the condenser 2, and then improve the overall heat dissipation effect of the thermosyphon heat dissipation device.
[0113] For example, the embodiment of the present disclosure can arrange the baffle 72 in the main pipe 56 or the first adapter pipe 521, wherein the cross-sectional area of the baffle 72 in the main pipe 56 is less than the cross-sectional area inside the main pipe 56, and the cross-sectional area of the baffle 72 in the first adapter pipe 521 is less than the cross-sectional area inside the first adapter pipe 521.
[0114] As shown in Figure 8 , the baffle 72 in the embodiment of the present disclosure can be a baffle plate. The baffle plate can be semicircular and connected with part of the inner wall of the adapter 52, so as to achieve flow resistance to the working medium. When the working medium contacts the baffle plate, the liquid medium can be attached to the baffle plate, so as to achieve separation from the vapor working medium. The separated liquid working medium can flow to the liquid collecting interface under the action of gravity and be recycled to the evaporation main body 11 through the liquid collecting pipe 51.
[0115] However, the baffle 72 can also be a porous plate (as shown in Figure 9 ) or a filter filler such as a wire mesh, so as to strengthen the flow resistance of the working medium inside the adapter 52 and enhance the vapor-liquid separation effect of the working medium.
[0116] As shown in Figure 2 and Figure 5As shown, in some embodiments, the inlet structure can include a first header pipe 22, which is arranged at one side of the condensing main body 21 and communicates with the interior of the condensing main body 21, and at least one gas inlet port is arranged on the first header pipe 22 and communicates with the interior of the first header pipe 22, and the gas inlet port communicates with the second end of the first pipe 61, so that the working medium in the first pipe 61 can be delivered into the condensing main body 21.
[0117] In some embodiments, the gas-liquid separator can include the first pipe 61, and the inlet structure can include the first header pipe 22. The first end of the first pipe 61 communicates with the gas outlet 12, and the second end of the first pipe 61 communicates with the inlet structure. At this time, the first header pipe 22 can also be provided with a liquid collecting port which communicates with the interior of the first header pipe 22, and the liquid collecting port is arranged at the bottom of the first header pipe 22 and communicates with the first end of the liquid collecting pipe 51.
[0118] For a more detailed description of the above-mentioned technical solutions, please refer to the following specific embodiments. Figure 10 As shown, in the embodiments of the present disclosure, the liquid collecting port is arranged on the flow path between the condensing main body 21 and the first pipe 61. The working medium is gas-liquid separated in the first header pipe 22, the separated liquid working medium flows to the liquid collecting port, and then flows back to the evaporating main body 11 through the liquid collecting pipe 51. The remaining working medium can flow into the condensing main body 21 through the inlet structure, and then be cooled and condensed by the condensing main body 21.
[0119] Further, the inlet structure can also include a fourth joint 24 and a fifth joint 25. The first end of the fourth joint 24 can communicate with the gas inlet port, and the second end of the fourth joint 24 can communicate with the gas outlet 12. The first end of the fifth joint 25 can communicate with the liquid collecting port, and the second end of the fifth joint 25 can communicate with the first end of the liquid collecting pipe 51.
[0120] Specifically, the second end of the fourth joint 24 can be sleeved on the outer periphery of the second end of the first pipe 61, so as to facilitate the assembly and sealing between the first pipe 61 and the first header pipe 22. The fifth joint 25 can be sleeved on the outer periphery of the first end of the liquid collecting pipe 51, so as to facilitate the assembly and sealing between the liquid collecting pipe 51 and the first header pipe 22.
[0121] In this way, the axis of the fourth joint 24 can deviate from the axis of the first header pipe 22, so that the working medium entering the first header pipe 22 from the gas outlet 12 can flow in the first header pipe 22. The centrifugal force generated by the rotational flow of the working medium can be more conducive to the gas-liquid separation of the working medium.
[0122] In the embodiment of the present disclosure, the cross-sectional area inside the first collecting pipe 22 can be greater than or equal to the cross-sectional area inside the first pipe 61, so as to ensure that the cross-sectional area inside the first collecting pipe 22 is large enough to achieve gas-liquid separation of the working fluid, ensure the effective sedimentation of the liquid working fluid in the working fluid, and reduce the carrying capacity of the vapor working fluid for the liquid working fluid.
[0123] like Figure 11 As shown, in some embodiments, a deflector 72 can be provided inside the first manifold 22, and the cross-sectional area of the deflector 72 is smaller than the cross-sectional area inside the first manifold 22. Therefore, when the working medium flows inside the first manifold 22, the residence time of the working medium inside the first manifold 22 can be extended by the deflector 72, so as to extend the gas-liquid separation time of the working medium inside the first manifold 22, improve the dryness of the working medium entering the condenser 2, and then improve the overall heat dissipation effect of the thermal siphon heat dissipation device.
[0124] For example, the deflector 72 in the embodiment of the present disclosure may be a filter filler such as a deflector plate, a porous plate, or a wire mesh, so as to enhance the flow resistance of the working medium inside the first collecting pipe 22 and improve the vapor-liquid separation effect of the working medium.
[0125] like Figure 12 As shown, in some embodiments, the first header 22 may include a first header 221 , a second connection portion 222 , and a second header 223 .
[0126] The first collecting portion 221 can extend along the horizontal direction X. The first collecting portion 221 is arranged on one side of the condensation main portion 21 and is connected to the interior of the condensation main portion 21. The air inlet interface is arranged on the first collecting portion 221 and is connected to the interior of the first collecting portion 221.
[0127] The first manifold 221 may be tubular in shape. The axis of the fourth joint 24 may deviate from the axis of the first manifold 221, so that the working medium entering the first manifold 22 from the gas outlet 12 can rotate and flow within the first manifold 221. The centrifugal force generated by the rotating flow of the working medium can further facilitate gas-liquid separation of the working medium.
[0128] The second collecting section 223 can extend in the horizontal direction, and the second collecting section 223 and the first collecting section are arranged in the vertical direction, and the second collecting section 223 is lower than the first collecting section 221. The liquid collecting interface is provided on the second collecting section 223 and is connected to the interior of the second collecting section 223. The axis of the liquid collecting interface extends in the vertical direction.
[0129] For example, the second collecting portion 223 may be in a tubular shape.
[0130] The liquid collecting interface may be provided at the bottom of the second manifold 223 to collect the liquid working medium separated from the working medium.
[0131] The opposite ends of the first and second collecting portions 221 and 223 in their respective extension directions can be sealed ends.
[0132] For example, the opposite ends of the first collecting portion 221 in its extension direction can be sealed by the end cap 71, and the opposite ends of the second collecting portion 223 in its extension direction can be sealed by the end cap 71.
[0133] The axial direction of the first collecting portion 221 can be parallel to the axial direction of the second collecting portion 223.
[0134] The second connecting portion 222 is arranged between the first and second collecting portions 221 and 223, and a plurality of through holes are arranged on the second connecting portion 222 in a horizontal direction, and the through holes can communicate the first and second collecting portions 221 and 223.
[0135] In the embodiment of the present disclosure, the second connecting portion 222 can extend along the axial direction of the first collecting portion 221, and the top surface shape of the second connecting portion 222 can be adapted to the bottom surface shape of the first collecting portion 221, and the bottom surface shape of the second connecting portion 222 can be adapted to the top surface shape of the second collecting portion 223.
[0136] For example, when the first and second collecting portions 221 and 223 are both in the shape of a cylindrical body, the top and bottom surfaces of the second connecting portion 222 can be in the shape of an adapted circular arc surface, so as to realize the sealed connection of the second connecting portion 222 with the first and second collecting portions 221 and 223.
[0137] It should be noted that the size of the through holes on the second connecting portion 222 in the embodiment of the present disclosure can be determined according to actual conditions, so as to effectively sink the liquid working medium in the first collecting portion 221 into the second collecting portion 223, while effectively improving the problem of the liquid working medium being entrained by the airflow into the condenser 2. That is, the embodiment of the present disclosure can adjust the size and number of the through holes to realize controlled intercommunication, so as to improve the vapor-liquid separation effect of the working medium in the first collecting tube 22.
[0138] In some embodiments, the extension direction of the first collecting tube 22 can form a specific angle with the horizontal direction X, and the value of the specific angle is greater than 0 and less than 180°, so that the flow path inside the first collecting tube 22 can be arranged obliquely relative to the horizontal direction X, thereby facilitating the vapor-liquid separation of the working medium inside the first collecting tube 22 under the action of gravity, so as to improve the dryness of the working medium entering the condenser 2.
[0139] The top end of the first collecting tube 22 is a sealed end, and the bottom end of the first collecting tube 22 forms a liquid collecting interface, and in the vertical direction Z, the gas inlet interface is higher than the liquid collecting interface.
[0140] For example, as shown in Figure 13 The first manifold 22 can extend along the vertical direction Z, so that the working medium entering the inside of the first manifold 22 can be separated into gas and liquid under the action of gravity. The top end of the first manifold 22 can be sealed by the end cover 71.
[0141] The gas inlet can be arranged at the bottom of the first manifold 22, but is not limited thereto, and can also be arranged at the top or any other position of the first manifold 22, which can be determined according to actual conditions.
[0142] In some embodiments, the liquid inlet 13 and the gas outlet 12 can be arranged at opposite ends of the evaporation main body 11, and the gas outlet 12 is higher than the liquid inlet 13 in the vertical direction Z.
[0143] For example, when the evaporation main body 11 extends along the vertical direction Z, the gas outlet 12 can be arranged at the top of the evaporation main body 11, and the liquid inlet 13 can be arranged at the bottom of the evaporation main body 11, so that the vaporized working medium can be separated from the liquid working medium and leave the evaporation main body 11 through the gas outlet 12.
[0144] In some embodiments, the thermosyphon heat dissipation device can include a liquid return pipe 41, the opposite ends of the liquid return pipe 41 are respectively connected to the outlet structure and the liquid inlet 13, and the working medium condensed by the condensation main body 21 flows to the outlet structure and returns to the evaporation main body 11 through the liquid return pipe 41 and the liquid inlet 13, so as to ensure the continuous operation of the thermosyphon heat dissipation device.
[0145] In the embodiment of the present disclosure, the second end of the liquid collecting pipe 51 can be connected to and communicated with the outlet structure of the condenser 2, which can be referred to as shown in Figure 14
[0146] It should be noted that in actual work, the evaporation device 1 and the condenser 2 in the thermosyphon heat dissipation device usually need to be physically spaced in space by sheet metal structure or the like. In the embodiment of the present disclosure, the second end of the liquid collecting pipe 51 is connected to and communicated with the outlet structure of the condenser 2, which can reduce the design and implementation difficulty of the physical spacing between the evaporation device 1 and the condenser 2.
[0147] At the same time, by connecting the second end of the liquid receiving tube 51 to the outlet structure of the condenser 2 and communicating with the outlet structure, while allowing the liquid working medium in the liquid receiving tube 51 to flow back to the evaporation main body 11 through the outlet structure and the liquid inlet 13, the liquid receiving tube 51 can also be moved away from the evaporation main body 11, thereby improving the situation where the heat from the evaporation main body 11 is transferred to the condenser 2 through the liquid receiving tube 51 due to the close distance between the liquid receiving tube 51 and the evaporation main body 11, thereby improving the heat dissipation efficiency of the condenser 2. However, the second end of the liquid receiving tube 51 in the embodiment of the present disclosure can also be directly connected to the liquid inlet 13, and the specific connection can be determined according to actual conditions.
[0148] In some embodiments, the outlet structure may include a second manifold 23 , the interior of which is in communication with the condensation main body 21 , so as to collect the liquid working medium condensed by the condensation main body 21 .
[0149] In the embodiment of the present disclosure, the second end of the liquid collecting pipe 51 can be connected to the second collecting pipe 23 and communicate with the second collecting pipe 23.
[0150] For example, the second end of the liquid collecting tube 51 can be connected to the end of the second manifold 23 near the liquid collecting interface. However, the second end of the liquid collecting tube 51 can also be connected to any other position besides the end of the second manifold 23 near the liquid collecting interface, and the specific location can be determined according to actual conditions.
[0151] When the second collecting pipe 23 extends along the vertical direction Z, the top end of the second collecting pipe 23 can be a sealed end, the bottom end of the second collecting pipe 23 can be connected to the first end of the return liquid pipe 41, and the second end of the return liquid pipe 41 can be connected to the liquid inlet 13, so that the liquid working medium condensed in the condensation main body 21 can be collected through the second collecting pipe 23, and then flow back to the evaporation main body 11 through the return liquid pipe 41 and the liquid inlet 13 in sequence.
[0152] In some embodiments, the condenser 2 may be an integrally brazed parallel flow heat exchanger.
[0153] Specifically, if Figure 15 As shown, the condenser main body 21 in the condenser 2 may include multiple condenser tubes 211 and a heat sink 212. The multiple condenser tubes 211 may be arranged in parallel and spaced apart. Each condenser tube 211 may have at least one through-hole condensation channel for circulating the working medium. The opposite ends of the condenser tubes 211 are respectively connected to an inlet structure and an outlet structure. The condenser main body 21 receives the working medium from the inlet structure through the condenser tubes 211 and condenses it. The condensed working medium may then exit the condenser tubes 211 through the outlet structure.
[0154] In the embodiment of the present disclosure, the condenser 211 can be partially embedded in the first manifold 22. For details, please refer toFigure 11 As shown, the cross-sectional area of the portion of the condensing pipe 211 embedded in the first collecting pipe 22 can be less than the cross-sectional area of the first collecting pipe 22, so that the condensing pipe 211 is in communication with the first collecting pipe 22, and the first collecting pipe 22 is used to collect the working medium, so that the working medium can flow uniformly and stably into the plurality of condensing pipes 211.
[0155] In addition, when the liquid return port is arranged on the first collecting pipe 22, the portion of the condensing pipe 211 embedded in the first collecting pipe 22 can also be used as the baffle 72 in the first collecting pipe 22, which can strengthen the gas-liquid separation of the working medium in the first collecting pipe 22, and can also simplify the preparation difficulty of the condenser 2 as a whole.
[0156] In the embodiment of the present disclosure, the condensing pipe 211 can be partially embedded in the second collecting pipe 23, and the cross-sectional area of the portion of the condensing pipe 211 embedded in the second collecting pipe 23 can be less than the cross-sectional area of the second collecting pipe 23, so that the condensing pipe 211 is in communication with the second collecting pipe 23, and the second collecting pipe 23 is used to collect the working medium.
[0157] The heat dissipation member 212 is arranged between the adjacent two condensing pipes 211, and the heat dissipation member 212 can include a plurality of heat dissipation plates arranged along the extension direction of the condensing pipe 211, and the opposite ends of the heat dissipation plates are respectively in abutment with the adjacent two condensing pipes 211. By arranging the heat dissipation member 212 between the adjacent two condensing pipes 211, the heat dissipation area of the condensing main body part 21 can be increased, and the heat dissipation efficiency of the condensing main body part 21 can be improved.
[0158] In some embodiments, the evaporation main body part 11 can be a flat plate-shaped cavity, which can be specifically referred to as Figure 2 and Figure 14 As shown, the power device needing heat dissipation can be attached and installed on the plate surface of the evaporation main body part 11 to transfer heat to the evaporation main body part 11 and achieve heat dissipation.
[0159] When the thermosyphon heat dissipation device works, the liquid working medium in the evaporation main body part 11 absorbs heat from the heat source and vaporizes, the gas-liquid mixed working medium enters the gas-liquid separator and is separated into liquid and gas under the action of gravity, the separated liquid working medium can flow back to the evaporation main body part 11 through the liquid collecting pipe 51, and the remaining working medium can flow into the condensing main body part 21 through the inlet structure, and then flow back to the evaporation main body part 11 through the outlet structure and the liquid return port, so as to realize the heat dissipation function repeatedly.
[0160] But not limited to this, the evaporation main body part 11 in the embodiment of the present disclosure can also be a parallel flow heat exchanger integrally brazed.
[0161] Specifically, as shown in Figure 16 and Figure 17As shown, the evaporation main body 11 can include multiple flow tubes 111 and a heat sink 112. The multiple flow tubes 111 can be arranged in parallel and spaced apart. Each flow tube 111 is provided with at least one through-hole evaporation channel for the flow of the working medium. The opposite ends of the flow tube 111 are connected to the liquid inlet 13 and the gas outlet 12, respectively, so that the evaporated working medium can be transported to the gas-liquid separator through the gas outlet 12, and the liquid working medium can be recovered through the liquid inlet 13.
[0162] The heat absorbing member 112 is arranged between two adjacent flow tubes 111. The heat absorbing member 112 may include a plurality of heat dissipation plates arranged along the extension direction of the flow tube 111. The opposite ends of the heat dissipation plates are respectively in contact with the two adjacent flow tubes 111. In the embodiment of the present disclosure, by arranging the heat absorbing member 112 between the two adjacent flow tubes 111, the heat absorption area of the evaporation main body 11 can be increased, which can help improve the heat absorption capacity of the evaporation main body 11.
[0163] It should be noted that the evaporator 1 in the embodiment of the present disclosure can be used to absorb air heat source to achieve control of air temperature.
[0164] In some embodiments, the thermosiphon heat dissipation device may further include a liquid filling tube 42 , which may be connected to the interior of the thermosiphon heat dissipation device at any convenient location. The thermosiphon heat dissipation device may be evacuated and a working fluid may be injected through the liquid filling tube 42 .
[0165] For example, one end of the liquid filling tube 42 may be connected to the second manifold 23 .
[0166] like Figure 18 As shown, in some embodiments, the thermal siphon heat dissipation device may include an evaporator 1, multiple condensers 2 and multiple gas-liquid separators, the gas-liquid separators correspond one-to-one to the condensers 2, and the condensers 2 can obtain the working fluid from the evaporator 1 through the corresponding gas-liquid separators.
[0167] Among them, multiple air outlets 12 and liquid inlets 13 can be set on the evaporation main body 11, and the air outlets 12 and air inlets can correspond one-to-one to the gas-liquid separators, so that the gas-liquid separator can obtain the vaporized working medium from the corresponding air outlet 12, and return the liquid working medium condensed by the condenser 2 to the evaporation main body 11 through the corresponding liquid inlet 13, so as to improve the efficiency of gas outlet of the vapor working medium and the efficiency of liquid return of the liquid working medium.
[0168] However, the present invention is not limited thereto. In the embodiment of the present disclosure, an air outlet 12 and a liquid inlet 13 may be provided on the evaporation main body 11. In this case, a plurality of gas-liquid separators may be connected to one air outlet 12 at the same time, and the outlet structures on a plurality of condensers 2 may be connected to one liquid inlet 13 at the same time, thereby simplifying the preparation process of the evaporation main body 11.
