Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat dissipation of communication equipment, in particular to an air-cooled radiator with adjustable fin spacing. Background Art
[0002] With the rapid development of 5G communication technology, the integration and assembly density of communication equipment are constantly improving, resulting in a sharp increase in equipment power consumption and heat generation. Among all the components of communication equipment, the upper temperature limit of pump lasers and optical modules is relatively low, and the shell temperature is usually limited to 70℃ or 75℃. The space compression, pluggability requirements and low temperature specifications have brought huge challenges to the heat dissipation of communication equipment.
[0003] The fin heat sink is a commonly used heat dissipation structure in the communication industry. From the heat dissipation process of the fin heat sink, it is mainly divided into three steps: heat absorption, heat conduction, and heat dissipation. It uses thermal interface materials to absorb the heat of the heating element to the heat sink base, and then transfers the heat from the base to the heat dissipation fins through heat conduction. Finally, the heat is dissipated to the surrounding environmental fluid through the fins on the surface of the heat sink. The purpose of using a fin heat sink is to promote more efficient heat transfer between the heating element and the environment.
[0004] The fins in the existing fin heat sink are relatively thick, which easily causes the temperature boundary layers of the two fins to overlap and cross, resulting in a small heat dissipation area, affecting the heat transfer on the surface of the fin heat sink and reducing the heat exchange efficiency. It is usually only suitable for natural convection heat dissipation, which has low requirements for heat exchange efficiency. It cannot meet the requirements for forced convection heat dissipation, which has high requirements for heat exchange efficiency. Therefore, the existing fin heat sink is difficult to cope with different heat dissipation conditions.
[0005] In view of this, overcoming the defects of the prior art is an urgent problem to be solved in the field of this technology. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0037] Embodiment 1:
[0038] Embodiment 1 of the present invention provides an air-cooled heat sink with adjustable fin spacing, such as Figure 1 and Figure 2 As shown, it includes: a plurality of self-adjusting components 1, a heat dissipation base 2, an outer baffle 3 and a guide rod 4, wherein:
[0039] The two outer baffles 3 are arranged on both sides of the heat dissipation base 2, and the guide rod 4 is arranged between the two outer baffles 3; the self-adjusting component 1 includes two movable fins 11, and the two movable fins 11 are movably sleeved on the guide rod 4, and a first ventilation interval 12 is formed between the two movable fins 11. When the wind speed is less than or equal to the first preset threshold, the two movable fins 11 between adjacent self-adjusting components 1 are in contact with each other; Figure 3 and Figure 4 As shown, when the wind speed is greater than a first preset threshold, the two movable ribs 11 between adjacent self-adjusting components 1 are separated.
[0040] It should be noted that the air-cooled radiator with adjustable fin spacing is a heat dissipation structure, and the heat dissipation base 2 is located at the bottom of the entire heat dissipation structure. The heat of the heating element can be absorbed to the heat dissipation base 2 through the thermal conductive interface material, and then the heat is transferred from the heat dissipation base 2 to the self-adjusting component 1 through heat conduction, and then the heat is dissipated to the surrounding ambient fluid through the self-adjusting component 1.
[0041] In this embodiment, one end of the guide rod 4 is vertically connected to the inner surface of one of the outer baffles 3, and the other end of the guide rod 4 is vertically connected to the inner surface of the other outer baffle 3. The two guide rods 4 are parallel to each other, and multiple self-adjusting components 1 are sleeved on the two guide rods 4. The multiple self-adjusting components 1 are arranged side by side, that is, multiple active ribs 11 are sleeved on the guide rods 4 side by side. When the wind speed is less than or equal to the first preset threshold, the two active ribs 11 between two adjacent self-adjusting components 1 fit together. It should be noted that if Figure 1 and Figure 2 As shown, “two movable ribs 11 between two adjacent self-adjusting components 1” does not mean that two additional movable ribs 11 are provided between the two adjacent self-adjusting components 1, but means that the two inner movable ribs 11 of the two adjacent self-adjusting components 1 fit together.
[0042] A first ventilation gap 12 is formed between two movable fins 11 in the same self-adjusting component 1 as a heat dissipation duct. In this embodiment, a plurality of guide rods 4 can be arranged between the two outer baffles 3, and a plurality of self-adjusting components 1 can be arranged on every two guide rods 4. Figure 1 For example, Figure 1 Six guide rods 4 are arranged in the middle, and nine self-adjusting components 1 are arranged side by side on every two guide rods 4. In this embodiment, the first preset threshold value is set by a person skilled in the art. In this embodiment, the material used for the heat dissipation base 2, the movable ribs 11 and the outer baffle 3 can be aluminum alloy or magnesium alloy. In this embodiment, at least two guide holes are arranged on the movable ribs 11, and the two guide holes are respectively movably sleeved on the two guide rods 4.
[0043] In this embodiment, the movable sleeve connection may be that the movable rib 11 can slide relative to the guide rod 4 while being sleeved with the guide rod 4. Figure 3 As shown, Figure 3 The solid arrow in the middle indicates the air inlet direction. Figure 3 The solid arrow on the movable rib 11 is the sliding direction of the movable rib 11 .
[0044] Figure 1 and Figure 2 The fin thickness of the air-cooled radiator with adjustable fin spacing is relatively thick (equivalent to two thinner active fins 11 fitted together to form a thicker fin), and the width of the ventilation interval is greater than or equal to the fin height to cope with natural convection cooling, which is a condition with low wind speed. Figure 3 and Figure 4 As shown, in this embodiment, the movable rib 11 can be movably sleeved on the guide rod 4, and a windward inclined surface is also provided on the end surface of the movable rib 11 facing the wind direction. When the wind speed is greater than the first preset threshold value (i.e., the forced convection condition), the larger wind speed can drive the movable rib 11 to slide on the guide rod 4, and separate the two movable ribs 11 that were originally in contact with each other, so that a gap is generated between two adjacent self-adjusting components 1, so that the thickness of the rib becomes thinner, and the heat dissipation area is increased, thereby improving the heat dissipation efficiency to cope with the forced convection.
[0045] In this embodiment, in order to ensure that the movable fins 11 can slide in the corresponding direction under the influence of wind, Figure 3 As shown, the end surface of the movable rib 11 is provided with a first windward inclined surface 111, the inclination direction of the first windward inclined surface 111 is toward the outside of the self-adjusting component 1, and the first windward inclined surfaces 111 of the two movable ribs 11 in the self-adjusting component 1 are arranged opposite to each other. When the first windward inclined surface 111 of the movable rib 11 is subjected to the force of wind, the wind will exert a vertical component force on the first windward inclined surface 111, thereby exerting a component force in the direction of the guide rod 4 on the entire movable rib 11. Since the inclination direction of the first windward inclined surface 111 is toward the self-adjusting component 1, the direction of the force exerted by the wind on the movable rib 11 is from outside to inside, toward the inside of the self-adjusting component 1.
[0046] like Figure 1 and Figure 2 As shown, when the wind speed is less than or equal to the first preset threshold, two adjacent self-adjusting components 1 fit together, and wind passes through the first ventilation interval 12 .
[0047] At this time, the two movable ribs 11 between the self-adjusting components 1 are in close contact with each other and have a relatively thick thickness.
[0048] like Figure 3 and Figure 4As shown, when the wind speed is greater than the first preset threshold, the two movable ribs 11 of the self-adjusting component 1 slide toward each other, the first ventilation interval 12 is reduced, and the second ventilation interval 5 is between two adjacent self-adjusting components 1, and the wind passes through the reduced first ventilation interval 12 and the second ventilation interval 5.
[0049] like Figure 1 and Figure 2 As shown, in this embodiment, when the heat dissipation requirement is low, the wind speed is less than or equal to the first preset threshold value, at this time, the two movable ribs 11 between the two adjacent self-adjusting components 1 are in contact with each other, the overall heat dissipation area is relatively small, and the self-adjusting component 1 does not need to be changed; Figure 3 and Figure 4 As shown, when the heat dissipation requirement increases, the wind speed is greater than the first preset threshold, and the two movable ribs 11 of the self-adjusting component 1 slide along the guide rod 4 in opposite directions, so that the two movable ribs 11 between the self-adjusting component 1 are separated, and the two surfaces of the two movable ribs 11 that were originally fitted together are exposed to the outside, thereby increasing the overall heat dissipation area, and the thickness becomes thinner, thereby improving the heat dissipation efficiency.
[0050] The component force exerted by the wind on the movable fin 11 along the direction of the guide rod 4 will cause the movable fin 11 to continue to slide, causing the two movable fins 11 in the same self-adjusting component 1 to fit together, resulting in the disappearance of the first ventilation interval 12. In order to solve this problem, different roughness or abutment platforms can be set on the guide rod 4 between the two movable fins 11 in the same self-adjusting component 1, or this embodiment also involves the following designs:
[0051] like Figure 4 As shown, in order to avoid the aforementioned problem, a spring 13 can also be provided on the guide rod 4 between the two movable fins 11 in the same self-adjusting component 1, thereby preventing the two movable fins 11 in the same self-adjusting component 1 from directly contacting each other. In addition, another purpose of providing the spring 13 is to ensure that the first ventilation interval 12 between the two movable fins 11 in the same self-adjusting component 1 is automatically restored when the wind speed is low.
[0052] Specifically, Figure 4 As shown, the self-adjusting component 1 further includes a spring 13 ; the spring 13 is disposed between two movable ribs 11 of the self-adjusting component 1 and sleeved on the guide rod 4 .
[0053] like Figure 5As shown, when the wind speed is less than or equal to the first preset threshold, the two adjacent self-adjusting components 1 are fitted together, the width of the first ventilation gap 12 is the first preset length, and the spring 13 is compressed to the first preset length; the elastic restoring force of the spring 13 at the first preset length is equal to the component force applied to the movable rib 11 in the direction of the guide rod 4 by the wind speed of the first preset threshold.
[0054] like Figure 5 As shown, in this embodiment, when the heat dissipation requirement is low and the wind speed is less than or equal to the first preset threshold, the spring 13 is not fully compressed. At this time, the width of the first ventilation gap 12 is the first preset length. The elastic restoring force generated by the spring 13 of the first preset length needs to ensure that when the wind is not strong enough, the width of the first ventilation gap 12 will not decrease, the entire heat dissipation structure will not change, and the heat dissipation area does not need to be increased.
[0055] like Figure 4 As shown, when the wind speed is greater than the first preset threshold and less than or equal to the second preset threshold, the two movable ribs 11 of the self-adjusting component 1 slide toward each other, the first ventilation interval 12 is reduced, and the second ventilation interval 5 is between two adjacent self-adjusting components 1, and the wind passes through the reduced first ventilation interval 12 and the second ventilation interval 5.
[0056] like Figure 4 As shown, in this embodiment, when the heat dissipation requirement is high, if the wind speed is greater than the first preset threshold and less than or equal to the second preset threshold, the component force applied by the wind speed to the active rib 11 in the direction of the guide rod 4 is greater than the elastic restoring force of the spring 13 under the first preset length, so the two active ribs 11 in the same self-adjusting component 1 slide toward each other, and the spring 13 is continuously compressed until the elastic restoring force of the spring 13 is equal to the component force applied by the current wind speed to the active rib 11 in the direction of the guide rod 4, at which time the forces on both sides of the active rib 11 are balanced and the sliding stops. During the sliding process, the two active ribs 11 in the self-adjusting component 1 are separated from the active ribs 11 in other self-adjusting components 1, and the thickness is reduced. At the same time, the first ventilation interval 12 is reduced, the second ventilation interval 5 is increased, and the heat dissipation surface area and wind resistance are increased.
[0057] When the wind speed is greater than a second preset threshold, the width of the first ventilation gap 12 is a second preset length, and the spring 13 is compressed to the second preset length; when the length of the spring 13 is the second preset length, the spring 13 is maximally compressed.
[0058] In this embodiment, when the heat dissipation requirement is high, if the wind speed is greater than the second preset threshold value, the component force applied by the wind speed to the movable rib 11 in the direction of the guide rod 4 is already greater than the elastic restoring force of the spring 13 in the fully compressed state. At this time, the spring 13 has been compressed to the limit and will not be further compressed. Therefore, the two movable ribs 11 in the same self-adjusting component 1 will stop sliding toward each other. At this time, the rib thickness on both sides of the ventilation interval, the first ventilation interval 12 and the second ventilation interval 5 no longer change, and the heat dissipation surface area and wind resistance no longer change.
[0059] In this embodiment, the first preset threshold value and the second preset threshold value are set by those skilled in the art according to the elastic coefficient of the spring 13 and the model of the spring 13; the first preset length and the second preset length are set by those skilled in the art according to the model of the spring 13 and the elastic coefficient of the spring 13.
[0060] In this embodiment, the elastic coefficient of the spring 13 may be 0.1 N / mm-2.5 N / mm.
[0061] like Figure 6 As shown, at least four guide rods 4 are arranged between the outer baffles 3, and at least two guide rods 4 form a group. A limiting platform 21 is arranged between each group of guide rods 4, and the movable ribs 11 on each group of guide rods 4 slide between two adjacent limiting platforms 21 or between the limiting platform 21 and the edge of the heat dissipation base 2.
[0062] In this embodiment, the width between two adjacent limit platforms 21 or the width between the limit platform 21 and the edge of the heat dissipation base 2 is greater than or equal to the length of the movable rib 11. In this embodiment, the roughness of the surface of the heat dissipation base 2 between two adjacent limit platforms 21 or between the limit platform 21 and the edge of the heat dissipation base 2 may be Ra1.6.
[0063] In this embodiment, for the two self-adjusting components 1 closest to the two outer baffles 3, one of the movable ribs 11 of the two self-adjusting components 1 is also in contact with the outer baffle 3. Therefore, when the heat dissipation requirement is high, the outer baffle 3 can also be separated from the movable rib 11 to further increase the heat dissipation area. This embodiment also involves the following design:
[0064] like Figure 6 As shown, second windward inclined surfaces 31 are provided on both end surfaces of the outer baffle plate 3 , and the inclination direction of the second windward inclined surfaces 31 is toward the inner side of the outer baffle plate 3 .
[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
