Description

Technical Field

[0001] The utility model relates to the technical field of radiators, in particular to a double-cavity thermosyphon radiator. Background Art

[0002] A heat sink is a device used to dissipate or transfer excess heat generated by a heat source. Its main function is to prevent heat from accumulating at the heat source and to prevent performance degradation or damage caused by overheating.

[0003] A thermosiphon radiator is a radiator that uses the thermosiphon effect to transfer heat. It includes an evaporator, a condenser and a return pipe. The evaporator and the condenser are connected by a return pipe, and the heat source is connected to the evaporator. When the heat emitted by the heat source is transferred to the evaporator, the coolant in the evaporator absorbs the heat and evaporates and expands to form an upward airflow. Under the action of the pressure difference between the evaporator and the condenser, the steam is transported to the condenser through the return pipe, so that the heat at the heat source is taken away. The steam is condensed and liquefied inside the condenser and flows back to the evaporator to achieve heat dissipation of the heat source.

[0004] Usually the condenser is set at a higher position than the evaporator. Due to the liquid level difference between the condenser and the evaporator, the steam density is low and the atmospheric pressure above is small, the steam can move upward naturally, and the condensed coolant returns to the evaporator under the action of its own gravity, realizing automatic circulation of the coolant. However, in order to form a liquid level difference between the condenser and the evaporator, more space is required to install the evaporator, condenser and reflux pipe, which is not conducive to being installed inside equipment with compact structure and small internal space. It is difficult to achieve the required pressure difference between the condenser and the evaporator, which may affect the circulation effect of the coolant and the heat dissipation effect of the heat source.

[0017] Beneficial effects of the utility model:

[0018] A dual-chamber thermal siphon radiator, comprising a heat sink, a first condensing component and a second condensing component, wherein a first heat sink and a second heat sink are provided inside the heat sink; the first condensing component comprises a first condenser, a first air pipe and a first liquid pipe, wherein two ends of the first air pipe are respectively connected to the top of the first heat sink and the input end of the first condenser, and two ends of the first liquid pipe are respectively connected to the bottom of the first heat sink and the output end of the first condenser; the second condensing component comprises a second condenser, a second air pipe and a second liquid pipe, wherein two ends of the second air pipe are respectively connected to the top of the second heat sink and the input end of the second condenser, and the second liquid pipe is respectively connected to the bottom of the second heat sink and the output end of the second condenser; the first heat sink and the second heat sink are arranged in sequence along a first direction, the first heat sink and the second heat sink are arranged independently of each other, and the first condensing component and the second condensing component are both arranged on the side of the heat sink away from the heat source.

[0031] See also Figure 1-Figure 3 The utility model provides a dual-cavity thermosyphon radiator, comprising a heat sink 1, a first condensing assembly 2 and a second condensing assembly 3, wherein a first heat sink 11 and a second heat sink 12 are provided inside the heat sink 1; the first condensing assembly 2 comprises a first condenser 21, a first air pipe 22 and a first liquid pipe 23, wherein two ends of the first air pipe 22 are respectively connected to the top of the first heat sink 11 and the input end of the first condenser 21, and two ends of the first liquid pipe 23 are respectively connected to the bottom of the first heat sink 11 and the output end of the first condenser 21; the second condensing assembly 3 comprises a second condenser 31, a second air pipe 32 and a second liquid pipe 33, wherein two ends of the second air pipe 32 are respectively connected to the top of the second heat sink 12 and the input end of the second condenser 31, and the second liquid pipe 33 is respectively connected to the bottom of the second heat sink 12 and the output end of the second condenser 31; the first heat sink 11 and the second heat sink 12 are arranged in sequence along a first direction X, the first heat sink 11 and the second heat sink 12 are arranged independently of each other, and the first condensing assembly 2 and the second condensing assembly 3 are both arranged on the side of the heat sink 1 away from the heat source.

[0032] Among them, the heat sink 1 is a rectangular plate structure, the first heat sink cavity 11 is arranged at the top of the heat sink 1, and the second heat sink cavity 12 is arranged at the bottom of the heat sink 1. The length direction of the first heat sink cavity 11 and the length direction of the second heat sink cavity 12 are both parallel to the length direction of the heat sink 1; the first condenser 21 and the second condenser 31 are both connected with a liquid injection pipe (not shown in the figure) for conveying coolant; the length direction of the first condenser 21 and the length direction of the second condenser 31 are parallel, the first condenser 21 and the second condenser 31 are arranged side by side on the side of the heat sink 1 away from the heat source, the first air pipe 22, the second air pipe 32, the first liquid pipe 23, and the second liquid pipe 33 are all aluminum pipes, the input end of the first liquid pipe 23 and the input end of the second liquid pipe 33 are both vertically arranged, and the input end of the first condenser 21 and the input end of the second condenser 31 of the same group are arranged on the same side, and the output end of the first condenser 21 and the output end of the second condenser 31 are arranged on the same side; the first direction X is a direction extending downward along the height direction of the heat sink 1.

[0033] It should be noted that the heat source is closely arranged on the side of the heat sink 1 facing away from the first condensation component 2 and the second condensation component 3, and the heat generated by the heat source is transferred to the first heat dissipation cavity 11 and the second heat dissipation cavity 12 through the heat sink 1, so that the coolant in the first heat dissipation cavity 11 and the coolant in the second heat dissipation cavity 12 evaporate and expand to form an ascending steam airflow, and flow to the top of the first heat dissipation cavity 11 and the top of the second heat dissipation cavity 12 respectively, and flow to the first condenser 21 and the second condenser 31 through the first air pipe 22 and the second air pipe 32 respectively for condensation and liquefaction. The liquefied coolant flows from the output end of the first condenser 21 and the output end of the second condenser 31 to the input end of the first liquid pipe 23 and the input end of the second liquid pipe 33 respectively, and circulates to the first heat dissipation cavity 11 and the second heat dissipation cavity 12 through the first liquid pipe 23 and the second liquid pipe 33 respectively.

[0034] In this way, by providing the first heat dissipation chamber 11 and the second heat dissipation chamber 12, and making the first air pipe 22 communicate with the top of the first heat dissipation chamber 11, and the second air pipe 32 communicate with the top of the second heat dissipation chamber 12, the coolant can enter the first air pipe 22 and the second air pipe 32 respectively in an upward direction (that is, a direction opposite to the first direction X) after evaporation, and enter the first condenser 21 and the second condenser 31 respectively under the action of airflow, and the coolant output from the first condenser 21 and the second condenser 31 flows to the first heat dissipation chamber 11 and the second heat dissipation chamber 12 under the action of gravity. While making the overall structure more compact, it is able to maintain sufficient pressure difference between the first heat dissipation cavity 11 and the first condenser 21, and between the second heat dissipation cavity 12 and the second condenser 31, to avoid obstruction of the flow of coolant or cooling steam due to insufficient liquid level difference between the first heat dissipation cavity 11 and the first condenser 21, and between the second heat dissipation cavity 12 and the second condenser 31, so that the coolant and coolant steam can form a circulation flow and sufficiently cool the heat source, thereby improving the circulation effect of the coolant and the heat dissipation effect on the heat source, and facilitating installation inside equipment with a smaller internal space.

[0035] It is understandable that the heat sink 1 can be made of a material with good thermal conductivity (such as aluminum alloy), and the materials of the heat sink 1, the first air pipe 22, the second air pipe 32, the first liquid pipe 23, and the second liquid pipe 33 can be flexibly adjusted to achieve good thermal conductivity, and no further examples are given here.

[0036] See also Figure 1 In some embodiments, two first condensation components 2 are provided, and the two first condensation components 2 are symmetrically arranged on both sides of the axis of the heat sink 1 in the first direction X; two second condensation components 3 are provided, and the two second condensation components 3 are symmetrically arranged on both sides of the axis of the heat sink 1 in the first direction X.

[0037] In this embodiment, a first condensation component 2 includes a first condenser 21 and a first liquid pipe 23, the input ends of the two first condensers 21 are arranged opposite to each other, and the output ends are arranged opposite to each other. A second condensation component 3 includes a second condenser 31 and a second liquid pipe 33, and the input ends of the two second condensers 31 are arranged opposite to each other.

[0038] In this way, two groups of the first condensation component 2 and the second condensation component 3 are each provided, which can effectively utilize the space on the side of the heat sink 1 away from the heat source, increase the heat dissipation area, enhance the heat dissipation efficiency of the heat sink 1, and at the same time make the heat dissipation effect at different positions of the heat sink 1 more uniform, avoiding poor local heat dissipation effect.

[0039] See also Figure 3 and Figure 4 In some embodiments, the heat sink 1 is provided with a first liquid inlet hole 13, the first heat dissipation cavity 11 is extended with a liquid storage cavity 111 along the first direction X, and the first liquid pipe 23 is connected with the liquid storage cavity 111 through the first liquid inlet hole 13, so that the coolant output by the first condenser 21 enters the liquid storage cavity 111 through the first liquid pipe 23.

[0040] In this embodiment, two first liquid inlet holes 13 are arranged at both ends of the heat sink 1, the longitudinal section of the liquid storage cavity 111 is triangular, and the first liquid pipe 23 is connected with the bottom of the liquid storage cavity 111 through the first liquid inlet hole 13; a second liquid inlet hole 15 is also provided on the side of the heat sink 1 away from the heat source, and the second liquid pipe 33 is connected with the second heat dissipation cavity 12 through the second liquid inlet hole 15.

[0041] In this way, the steam is liquefied after passing through the first condenser 21 and flows into the first liquid pipe 23. Since the input end of the first liquid pipe 23 is vertically arranged, the coolant flows into the liquid storage chamber 111 under the action of its own gravity, and gradually accumulates until it enters the first heat dissipation chamber 11. By setting up the cooling chamber, the distance between the output end of the first liquid pipe 23 and the input end of the first air pipe 22 can be increased, and a sufficient pressure difference can be maintained between the first condenser 21 and the first heat dissipation chamber 11, so as to improve the circulation effect of the coolant and the heat dissipation effect on the heat source.

[0042] See also Figure 1 In some embodiments, the first air pipe 22, the first condenser 21, and the first liquid pipe 23 are arranged in sequence along the first direction X, and the end of the first condenser 21 connected to the first liquid pipe 23 is inclined toward the first direction X (that is, the output end of the first condenser 21 is inclined downward); the second condenser 31, the second air pipe 32, and the second liquid pipe 33 are arranged in sequence along the first direction X, and the end of the second condenser 31 connected to the second liquid pipe 33 is inclined toward the first direction X (that is, the output end of the second condenser 31 is inclined downward).

[0043] In this embodiment, the first air pipe 22 is arranged on the top of the heat sink 1, and the first condenser 21 and the second condenser 31 are both arranged between the first air pipe 22 and the second air pipe 32, and the distance between the output end of the first liquid pipe 23 and the top surface of the heat sink 1 is smaller than the distance between the output end of the second liquid pipe 33 and the top surface of the heat sink 1 (that is, the output end of the first liquid pipe 23 is higher than the output end of the second liquid pipe 33); the output end of the second air pipe 32 is inclined in a direction away from the first direction X (that is, the output end of the second air pipe 32 is inclined upward).

[0044] In this way, the output ends of the first condenser 21 and the second condenser 31 are both tilted downward, so that the condensed coolant can automatically flow to the corresponding first liquid pipe 23 and second liquid pipe 33 under the action of gravity. The second air pipe 32 is tilted upward to guide the evaporated steam in the second heat dissipation cavity 12 into the second condenser 31, and the distance between the output end of the second air pipe 32 and the output end of the first liquid pipe 23 can be increased, so as to maintain a sufficient pressure difference between the second heat dissipation cavity 12 and the second condenser 31, thereby improving the circulation effect of the coolant. At the same time, it can make the structure more compact, reduce the floor space, and facilitate installation in equipment with smaller internal space.

[0045] See also Figure 2 and Figure 5 In some embodiments, a plurality of first air pipes 22 and a plurality of second air pipes 32 are provided, and the plurality of first air pipes 22 are connected to the first condenser 21 and the interior of the first heat dissipation cavity 11, and the plurality of second air pipes 32 are connected to the second condenser 31 and the interior of the second heat dissipation cavity 12. Further, the input ends of the plurality of first air pipes 22 are arranged along a direction perpendicular to the first direction X (that is, the input ends of the plurality of first air pipes 22 are arranged along the length direction of the heat dissipation plate 1); the output ends of the plurality of first air pipes 22 are arranged along a direction perpendicular to the side wall of the heat dissipation plate 1 away from the heat source (that is, the output ends of the plurality of first air pipes 22 are arranged along the thickness direction of the first condenser 21); the input ends of the plurality of second air pipes 32 are arranged along a direction perpendicular to the first direction X (that is, the input ends of the plurality of second air pipes 32 are arranged along the length direction of the heat dissipation plate 1), and the output ends of the plurality of second air pipes 32 are arranged along a direction perpendicular to the side wall of the heat dissipation plate 1 away from the heat source (that is, the output ends of the plurality of second air pipes 32 are arranged along the thickness direction of the second condenser 31).

[0046] In the present embodiment, three first air pipes 22 are provided in a first condensing component 2, and three second air pipes 32 are provided in a second condensing component 3. A first air outlet 14 is provided at a position corresponding to the first air pipe 22 on a side of the heat sink 1 facing away from the heat source, and the number of the first air outlets 14 is equal to the number of the first air pipes 22. A second air outlet 16 is provided at a position corresponding to the second air pipe 32 on a side of the heat sink 1 facing away from the heat source, and the length direction of the second air outlet 16 is parallel to the length direction of the heat sink 1, and the second air outlet 16 covers the input ends of all the second air pipes 32; the first air outlet 14 is connected to the first heat dissipation cavity 11, and the second air outlet 16 is connected to the second heat dissipation cavity 12.

[0047] In this way, the input ends of the multiple first air pipes 22 and the input ends of the multiple second air pipes 32 are all arranged in a direction perpendicular to the first direction X, which can make the steam at the top of the first heat dissipation cavity 11 and the steam at the top of the second heat dissipation cavity 12 evenly enter the first air pipes 22 and the second air pipes 32; the output ends of the multiple first air pipes 22 are arranged along the width direction of the first condenser 21, and the output ends of the multiple second air pipes 32 are arranged along the width direction of the second condenser 31, which can make the steam evenly enter the first condenser 21 and the second condenser 31, thereby improving the circulation effect of the coolant and the heat dissipation effect of the heat source.

[0048] It is understandable that the number of the first air pipes 22 and the number of the second air pipes 32 can be flexibly adjusted, and a plurality of first liquid pipes 23 and second liquid pipes 33 can also be provided, which will not be elaborated here.

[0049] See also Figure 1 and Figure 4 In some embodiments, the heat sink 1 is provided with a second air outlet 16 connected to the second heat dissipation cavity 12, and the second condensing assembly 3 further includes a connecting pipe 34, and a confluence cavity (not shown in the figure) is provided inside the connecting pipe 34, and the confluence cavity is connected to the second air outlet 16, and the input ends of all the second air pipes 32 are connected to the connecting pipe 34, so that the input ends of all the second air pipes 32 are connected to the second heat dissipation cavity 12 through the confluence cavity.

[0050] In this embodiment, the length direction of the confluence chamber is parallel to the length direction of the heat sink 1, and the second air pipe 32 is connected to the side of the connecting pipe 34 away from the heat sink 1, so that the steam in the second heat dissipation chamber 12 is first discharged to the confluence chamber through the second air outlet 16, and then enters the second air pipe 32 through the confluence chamber.

[0051] In this way, the steam can be buffered in the confluence cavity and evenly discharged into the second air pipe 32, so that the circulation of the coolant and the coolant steam is more stable, and the circulation effect of the coolant and the heat dissipation effect on the heat source are improved.

[0052] It can be understood that the heat sink 1 can also have second air outlet holes 16 corresponding to the number of second air pipes 32, and one second air outlet hole 16 is connected to one second air pipe 32. In this embodiment, the number of second air outlet holes 16 is set to be one, and its purpose is to buffer the steam in the confluence cavity and discharge it evenly into the second air pipe 32, so that the coolant vapor can flow smoothly and be condensed by the second condenser 31.

[0053] See also Figure 3 In some embodiments, the dual-chamber thermosyphon heat sink further includes a flow guide assembly 4, which includes a first flow guide block 41 and a second flow guide block 42. The first flow guide block 41 is disposed inside the first heat dissipation cavity 11, and the second flow guide block 42 is disposed inside the second heat dissipation cavity 12. Further, the first flow guide block 41 cooperates with the first heat dissipation cavity 11 to form a wavy first air guide channel 112, and the second flow guide block 42 cooperates with the second heat dissipation cavity 12 to form a wavy second air guide channel 121.

[0054] In this way, when the coolant in the first heat dissipation cavity 11 and the coolant in the second heat dissipation cavity 12 are heated and evaporated, the steam can be guided by the first guide block 41 and the second guide block 42, and the wavy first air guide channel 112 and the second air guide channel 121 can extend the flow path of the steam, so that the coolant can be fully evaporated, and the steam enters the first air pipe 22 and the second air pipe 32 respectively evenly and stably, thereby improving the circulation effect of the coolant and evenly dissipating the heat from various parts of the heat source.

[0055] It is understandable that the shapes of the first guide block 41 and the second guide block 42 can be flexibly adjusted according to actual needs, and the shapes of the first air guide channel 112 and the second air guide channel 121 can be the same or different, and are not limited to wavy shapes, but can also be zigzag shapes, straight lines, etc., which are not listed in detail here.

[0056] See also Figure 3 In some embodiments, the dual-chamber thermosyphon radiator further includes a partition rib 5, which is disposed inside the heat dissipation plate 1 and is used to separate the first heat dissipation cavity 11 from the second heat dissipation cavity 12. The width of the partition rib 5 ranges from 3 mm to 4 mm, and for example, the width of the partition rib 5 can be 3 mm, 3.5 mm, or 4 mm.

[0057] In this way, the partition ribs 5 can separate the first heat dissipation cavity 11 from the second heat dissipation cavity 12, thereby preventing the first heat dissipation cavity 11 and the second heat dissipation cavity 12 from interfering with each other and thus affecting the normal circulation of the coolant.

[0058] It is understandable that the width of the partition rib 5 can be flexibly adjusted according to the thickness of the heat dissipation plate 1 so as to achieve the disconnection between the first heat dissipation cavity 11 and the second heat dissipation cavity 12 , and no further examples are given here.
