[0028] Research revealed that the receiver is installed in a 3U chassis, which has standard dimensions of 13.33 cm (5.25 inches) high and 48.26 cm (19 inches) wide. Due to limited internal space, it is impossible to accommodate enough fans or high-volume fans. Therefore, the internal components of the receiver mainly rely on heat conduction. If the narrowband and broadband components are installed in the chassis, and they are irregularly installed directly in the chassis, there will be mutual interference during heat conduction due to the different heat generation of the two components, resulting in poor heat dissipation.

[0029] Based on the above research, this disclosure provides a sealed device and receiver for a receiver, which separates the narrowband portion and the wideband portion by a partition and adaptively sets the lower heat dissipation component and the upper heat dissipation component, thereby effectively improving the heat dissipation effect.

[0030] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] like Figures 1 to 4 As shown, at least one embodiment provides a sealed device comprising: a housing assembly 1, a partition 2, a lower heat dissipation assembly 3, and an upper heat dissipation assembly 4; wherein the partition 2 is located inside the housing assembly 1, the edge of the partition 2 is in contact with the housing assembly 1, the lower heat dissipation assembly 3 and the upper heat dissipation assembly 4 are respectively located on both sides of the partition 2 and connected to the partition 2; the lower heat dissipation assembly 3 and the upper heat dissipation assembly 4 dissipate heat from each component in the narrow band portion and each component in the wide band portion within the housing assembly 1, respectively, and conduct the heat from each component to the lower heat dissipation assembly 3 and the upper heat dissipation assembly 4, and conduct the heat to the external environment through the partition 2 and the housing assembly 1.

[0034] Specifically, thermal grease is applied to the surfaces of components with high power consumption and heat generation, allowing direct connection between the component surface and housing assembly 1 or indirect connection via partition 2, lower heat dissipation assembly 3, and upper heat dissipation assembly 4. This reduces the operating temperature of these components, preventing damage and aging, and extending their service life. Partition 2, lower heat dissipation assembly 3, and upper heat dissipation assembly 4 are reliably fixed to housing assembly 1 via guide rails and thermally conductive locking strips, using stainless steel screws, stainless steel flat washers, and stainless steel spring washers to ensure the equipment meets specified vibration and impact requirements.

[0035] In at least one embodiment, by setting a partition 2 inside the housing assembly 1 to separate the narrowband portion and the wideband portion of the receiver, and by adaptively setting the lower heat dissipation assembly 3 and the upper heat dissipation assembly 4 according to the different heat generation of the two, the heat dissipation effect can be effectively improved. At the same time, the narrowband portion with lower heat generation is set in the lower layer, and during the heat rise process, it is directly guided to the external environment through the partition 2 and the housing assembly 1, avoiding the problem of heat conduction interference. Furthermore, the partition 2, the lower heat dissipation assembly 3, and the upper heat dissipation assembly 4 can all increase the heat dissipation area, realizing rapid heat dissipation inside the chassis.

[0036] In at least one embodiment, please refer to Figure 1 , Figure 2The housing assembly 1 includes: a housing 11 and two first heat dissipation units 12; the upper cover plate 111 and the lower cover plate 112 of the housing 11 are each provided with a plurality of first heat dissipation grooves 113 to conduct heat; the two first heat dissipation units 12 are respectively connected to the two side plates 114 of the housing 11 to conduct heat.

[0037] Specifically, the enclosure 11 is made of rust-resistant aluminum, which not only meets the requirements of mechanical strength and weight, but also improves the heat dissipation effect.

[0038] Specifically, please refer to Figure 1 , Figure 2 By opening the first heat dissipation groove 113 in the upper cover plate 111 and the lower cover plate 112, the heat dissipation area can be increased and the heat dissipation effect can be improved.

[0039] Specifically, please refer to Figure 1 , Figure 2 By setting the first heat dissipation unit 12 on the side plate 114, the heat dissipation area can be increased and the heat dissipation effect can be improved.

[0040] In at least one embodiment, please refer to Figure 1 , Figure 2 The first heat dissipation unit 12 includes: a plurality of first heat dissipation fins 121; each of the first heat dissipation fins 121 is arranged sequentially on the corresponding side plate 114 to conduct heat.

[0041] Specifically, the function of the first heat sink 121 is to increase the heat dissipation area of ​​the side plate 114, which in turn helps to quickly guide the heat inside the enclosure 11 to the external environment.

[0042] In at least one embodiment, please refer to Figure 3 The lower heat dissipation assembly 3 includes: a first air blowing unit 31, a shielding cover 32, and a first back plate 33; the first air blowing unit 31, the shielding cover 32, and the first back plate 33 are connected to the partition 2, the first air blowing unit 31 is disposed facing the shielding cover 32, and the first back plate 33 is disposed perpendicular to the partition 2 and is attached to the housing assembly 1; the first air blowing unit 31 is configured to blow air onto the shielding cover 32 to dissipate heat from the components inside the shielding cover 32, so as to conduct heat to the partition 2 and the first back plate 33, and conduct it to the external environment through the housing assembly 1.

[0043] Specifically, the shielding cover 32 serves to conduct heat and provide electromagnetic shielding.

[0044] Specifically, the first blowing unit 31 can generate airflow in the lower layer to quickly remove the heat generated by the components inside the shield 32.

[0045] Specifically, the first back plate 33 serves to strengthen the connection between the partition 2 and the box 11.

[0046] Specifically, the first backplate 33 also facilitates wiring between the upper and lower layers.

[0047] Specifically, the first backplate 33 can also increase the contact area between the partition 2 and the housing 11, thereby improving the heat dissipation effect.

[0048] Specifically, the narrow band is installed inside the shielding cover 32. The narrow band has relatively low power consumption and low heat generation. It is stacked to occupy one layer and heat is transferred through the connection between the shielding cover 32 and the partition 2 and the box 11.

[0049] In at least one embodiment, please refer to Figure 3 The first air blowing unit 31 includes: a fan base 311, a first fan 312 and a plurality of second heat sinks 313; the fan base 311 is connected to the partition 2, the first fan 312 is mounted on the fan base 311 and the first fan 312 is positioned facing the shield 32, and each of the second heat sinks 313 is arranged sequentially on the fan base 311.

[0050] Specifically, the first fan 312 generates airflow towards the shield 32, while the narrow band portion inside the shield 32 generates relatively little heat. During the upward process, the heat is directly conducted to the external environment by the shield 32, the partition 2, and the housing assembly 1, thereby avoiding the problem of heat interference in the narrow band and the wide band.

[0051] Specifically, providing a second heat sink 313 on the fan mount 311 can reduce the impact of additional heat generated by the first fan 312.

[0052] In at least one embodiment, please refer to Figure 3 The shielding cover 32 is provided with a plurality of second heat dissipation slots 321, and the first back plate 33 is provided with a plurality of heat dissipation holes 331. By increasing the heat dissipation area, the heat dissipation effect is improved.

[0053] In at least one embodiment, please refer to Figure 4 The upper heat dissipation assembly 4 includes: a second air blowing unit 41, a plurality of first heat dissipation fins 42 and a second back plate 43; the second air blowing unit 41 and the second back plate 43 are connected to the partition 2, and each of the first heat dissipation fins 42 is mounted on the partition 2 so that each component is located between the corresponding first heat dissipation fin 42 and the partition 2, and the second air blowing unit 41 is arranged facing each of the first heat dissipation fins 42; the second back plate 43 is arranged perpendicular to the partition 2 and is attached to the housing assembly 1; the second air blowing unit 41 is configured to blow air onto each of the first heat dissipation fins 42 to dissipate heat from each component between the first heat dissipation fin 42 and the partition 2, so as to conduct heat to the partition 2 and the second back plate 43, and conduct it to the external environment through the housing assembly 1.

[0054] Specifically, the wide section is located on the upper layer, and a second air blowing unit 41 is installed on its side to accelerate the air circulation on its surface and transfer heat to the housing assembly 1. At the same time, the wide section is in close contact with the partition 2 to conduct heat dissipation and reduce the temperature of the wide section.

[0055] Specifically, the narrowband portion and the wideband portion are separated by the partition 2, which reduces heat interference between the two and also reduces electromagnetic interference.

[0056] Specifically, the placement of the first heat dissipation fin 42 can also improve the electromagnetic shielding effect. In at least one embodiment, please refer to Figure 4 The second air blowing unit 41 includes: a plurality of second fans 411; each second fan 411 is connected to the partition 2, and each second fan 411 is respectively arranged facing the corresponding first heat dissipation fin 42.

[0057] Specifically, to avoid excessive heat concentration, the wide section is installed on the upper layer to facilitate the upward circulation of heat. The first heat dissipation fin 42 with a reasonable depth is used, and a second fan 411 is installed on its side. The continuous blowing of the second fan 411 can accelerate the air circulation on its surface, transfer heat to the housing assembly 1, and accelerate the reduction of the temperature of the first heat dissipation fin 42.

[0058] In at least one embodiment, please refer to Figure 4 Several second heat dissipation fins 431 are arranged sequentially on the second back plate 43 to increase the heat dissipation area and improve the heat dissipation effect.

[0059] In at least one embodiment, please refer to Figure 4 The upper heat dissipation component 4 further includes: a heat-conducting layer 44 and a plurality of heat-conducting pipes 45; the heat-conducting layer 44 is located between the first heat dissipation fin 42 and the partition plate 2 and is in contact with the corresponding component, and the heat-conducting layer 44 is connected to the corresponding second heat dissipation fin 431 through the corresponding heat-conducting pipes 45.

[0060] Meanwhile, to ensure the normal operation of the broadband section, the heat-conducting layer 44 is made of brass, and with the brass heat-conducting key heat pipe, heat can be quickly transferred to the second back plate 43.

[0061] In summary, this utility model effectively improves heat dissipation by separating the narrowband and wideband portions of the receiver within the housing assembly using a partition. Furthermore, it adapts the lower and upper heat dissipation components to the different heat generation levels of the two portions, thereby avoiding heat conduction interference. Additionally, placing the narrowband portion, which generates less heat, in the lower layer allows the heat to be directly guided to the external environment through the partition and housing assembly during its rise, preventing heat conduction interference. Moreover, the partition, lower heat dissipation component, and upper heat dissipation component all increase the heat dissipation area, enabling rapid heat dissipation within the chassis.

[0062] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0063] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0064] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0065] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0066] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
