[0058] The present application embodiment provides an electrical device 100, see Figures 1 to 4The electrical device 100 includes a housing 10, a heat generating element 20, a diverter 30, a first airflow generator 40a, a box 50, a bellows 60, a second airflow generator 40b, a heating element 70, a heat sink 80, a third airflow generator 40c, a mounting plate 90a, a connecting plate 90b, and an adapter plate 90c.

The mounting plate 90a, the housing 50, the bellows 60 and the heating element 70 are all arranged in the first receiving chamber 101s. The second airflow generator 40b, the radiator 80 and the third airflow generator 40c are arranged in the second receiving chamber 103s. The heat generating element 20 is arranged in the housing 50. The first airflow generator 40a is arranged in the bellows 60. The housing 50 and the bellows 60 are connected. The diverter 30 is arranged in the bellows 60 and the second receiving chamber 103s. The blowing end of the first airflow generator 40a faces the diverter 30, the blowing end of the second airflow generator 40b faces the diverter 30, and the blowing end of the third airflow generator 40c faces the radiator 80. In addition, the mounting plate 90a is used for component installation, thereby expanding the function of the electrical device 100. The connecting plate 90b and the adapter plate 90c are both used for connecting the electrical device 100 with external devices. In the electrical device 100 provided in the embodiment of the present application, the heat generated by the heat generating part 20 is driven by the first airflow generator 40a to accelerate the circulation, and is internally circulated between the box body 50 and the bellows 60 through the diverter 30; in addition, the heat generated by the heat generating part 20 can also be diverted to the second receiving cavity 103s through the diverter 30, and then dissipated from the heat dissipation hole 10s after being cooled by the second airflow generator 40b, thereby achieving heat dissipation of the heat generating part 20.

In addition, the heat generated by the heating element 70 can be transferred to the radiator 80 in the second receiving cavity 103s, and then driven by the third airflow generator 40c to accelerate the circulation and dissipate from the heat dissipation hole 10s, thereby achieving the heat dissipation of the heating element 70 and improving the overall heat dissipation capacity and heat dissipation efficiency of the electrical device 100. In addition, since the heat generating element 20 is protected by the box 50, the heating element 70 and the radiator 80 are located in two different areas, the heat generating element 20 can not only dissipate heat but also prevent dust, and the heating element 70 can not only dissipate heat but also prevent dust.

The suction end of the second airflow generator 40b and the blowing end of the second airflow generator 40b are arranged opposite to each other, and the blowing end of the second airflow generator 40b is located at the other end of the second accommodating chamber 103s facing the diverter 30, and the second airflow generator 40b is connected to the first heat dissipation channel 30s.

[0076] It can be understood that the first airflow generator 40a is used to drive the heat generated by the heat generating element 20 to enter the first heat dissipation channel 30s, and further enter the box body 50 for circulation.

[0077] It can be understood that the suction end of the second airflow generator 40b is used to suck in a cooler airflow and drive it into the first heat dissipation channel 30s, thereby bringing the heat in the first heat dissipation channel 30s into the second receiving cavity 103s and then dissipating it from the heat dissipation hole 10s. Figure 3 In the airflow passage C1, the heat (i.e., airflow) generated by the heat generating part 20 entering the suction chamber 601 from the first through hole 501 is blocked and guided by the first guide surface 604, thereby quickly entering the suction end of the first airflow generator 40a, entering from the suction end of the first airflow generator 40a, and dissipating from the blowing end of the first airflow generator 40a. The airflow can enter the blowing chamber 603 through the first heat dissipation channel 30s, be guided by the second guide surface 605, and then quickly enter the box body 50 from the second through hole 502. After circulating in the box body 50, the heat generated by the heat generating part 20 in the box body 50 is brought into the suction chamber 601 of the bellows 60 through the first through hole 501 for internal circulation.

[0078] See also Figure 3 In the airflow passage C2, after the heat generated by the heat generating part 20 is driven by the first airflow generator 40a to accelerate circulation and dissipate from the blowing end of the first airflow generator 40a, the airflow can also enter the second receiving cavity 103s through the first heat dissipation channel 30s, and be blown out of the heat dissipation hole 10s of the shell 10 by the blowing end of the second airflow heat generator, so as to dissipate the heat generated by the heat generating part 20 to the outside of the shell 10 for external heat dissipation and cooling. Through the above-mentioned airflow passage C1 and airflow passage C2, the heat generated by the heat generating part 20 is circulated internally and dissipated externally to improve the cooling capacity and cooling efficiency of the heat generating part 20.

[0079] In some embodiments, see Figure 4 , the heat generating element 20 in the box body 50 is supported by a plurality of support columns 2, the plurality of support columns 2 are located in the box body 50, a receiving space 2s is formed between the plurality of support columns 2, and a part of the heat generating element 20 extends to the receiving space 2s. Through this arrangement, on the one hand, the arrangement form of the heat generating element 20 can be expanded, and on the other hand, the heat generating element 20 is supported by the plurality of support columns 2, forming a double-sided heat dissipation form of the heat generating element 20 along the supporting direction of the support columns 2, that is, the first direction D1 mentioned above. Then, the heat generated by the heat generating element 20 is driven by the first airflow generator 40a to accelerate the circulation and enter the box body 50 from the second through hole 502. After circulating in the box body 50, the heat generated by the heat generating element 20 in the box body 50 is brought into the suction chamber 601 of the bellows 60 through the first through hole 501, and the efficiency is high.

[0080] It is worth mentioning that please refer to Figure 3When the bellows 60 is recessed along the stacking direction of the first receiving chamber 101s toward the second receiving chamber 103s to form the suction chamber 601, the flow chamber 602, the blow-out chamber 603, the first guide surface 604, and the second guide surface 605, it is actually at the narrow neck of the flow chamber 602. Since the first airflow generator 40a is clamped in the flow chamber 602, one end of the diverter 30 is clamped in the flow chamber 602, that is, only the first airflow generator 40a clamped in the flow chamber 602 drives the heat generated by the heat-generating part 20 entering the suction chamber 601 to accelerate the flow and then dissipate it to the blow-out chamber 603. In addition, since the flow chamber 602 is the bellows 60 along the first receiving chamber 101s, the heat generated by the heat-generating part 20 entering the suction chamber 601 is driven to accelerate the flow and then dissipate it to the blow-out chamber 603. If a receiving chamber 101s is formed in the stacking direction of the second receiving chamber 103s, a trumpet-shaped inlet will inevitably be formed at the connection between the suction chamber 601 and the flow chamber 602, and a trumpet-shaped outlet will be formed at the connection between the blow-out chamber 603 and the flow chamber 602, thereby increasing the rate at which the heat generated by the heat generating element 20 flows from the suction chamber 601 into the flow chamber 602, and increasing the rate at which the airflow after passing through the first airflow generator 40a dissipates from the flow chamber 602 to the blow-out chamber 603, thereby accelerating the internal circulation of the heat generated by the heat generating element 20 between the box body 50 and the bellows 60, and increasing the rate and efficiency of the internal circulation of the heat generated by the heat generating element 20 between the box body 50 and the bellows 60.

[0081] In some embodiments, see Figure 6 The number of the first heat dissipation channels 30s of the diverter 30 is multiple, and the diverter 30 includes a plurality of first heat dissipation teeth 301 arranged at intervals, and the first heat dissipation channel 30s is formed between every two adjacent first heat dissipation teeth 301.

[0082] In some embodiments, see Figure 6 , the plurality of first heat dissipation teeth 301 are arranged at intervals along the third direction D3, and the plurality of first heat dissipation channels 30s formed between the plurality of first heat dissipation teeth 301 are arranged at intervals along the third direction D3. Figure 7 The heat generated by the heat generating element 20 can enter the blowing chamber 603 from the suction chamber 601 along the second direction D2 through the first heat dissipation channel 30s, and the heat generated by the heat generating element 20 can also enter the second receiving chamber 103s from one end of the first heat dissipation channel 30s located in the bellows 60 through the first heat dissipation channel 30s along the first direction D1, thereby realizing the above-mentioned internal circulation and external heat dissipation cooling cooling form.

[0083] It is worth mentioning that please refer to Figure 7In the embodiment of the present application, the housing 10 is separated into a first receiving chamber 101s and a second receiving chamber 103s by a partition 10m, and the various components are arranged in these two different areas, so that the heating element 70 in the first receiving chamber 101s and the heating element 20 in the box 50 can be waterproof and dustproof. In some embodiments, the diverter 30 is provided with a connector 3 extending in a direction parallel to the partition 10m, and the connector 3 is arranged around the diverter 30, and the connector 3 is sealed and connected to the partition 10m. Through this arrangement, at the mounting hole 102s on the partition 10m that connects the first receiving chamber 101s and the second receiving chamber 103s, due to the arrangement of the diverter 30 and the sealing connection of the connector 3 extending from the diverter 30 with the partition 10m, the sealing at the mounting hole 102s is achieved, thereby significantly improving the dustproof and waterproof functions of the heating element 20 and the heating element 70.

[0084] It is worth noting that the direction parallel to the partition 10m can be any direction parallel to the partition 10m, and the direction parallel to the partition 10m can be any direction perpendicular to the first direction D1, including the second direction D2 and the third direction D3. In some embodiments, the connector 3 can be sealed and connected to a side of the partition 10m and the first receiving chamber 101s through the seal 1, and the connector 3 can also be sealed and connected to a side of the partition 10m and the bellows 60 through the seal 1.

[0085] It is worth noting that in some embodiments, the above-mentioned box body 50, bellows 60, and second airflow generator 40b may not be provided, so that the heat generated by the heat generating part 20 can be achieved on the one hand through the first airflow generator 40a, the first heat dissipation channel 30s of the diverter 30 located at one end of the first receiving chamber 101s to achieve the goal of internal circulation and accelerating airflow circulation, and the heat generated by the heat generating part 20 can be achieved on the other hand through the first airflow generator 40a, the first heat dissipation channel 30s of the diverter 30 located at one end of the second receiving chamber 103s and the heat dissipation holes 10s provided on the shell 10 to achieve the goal of external heat dissipation and cooling.

[0086] For the above-mentioned heating element 70, heat sink 80, and third airflow generator 40c, please refer to Figure 4In some embodiments, the heating element 70 is also a functional module of the electrical device 100, which is used to realize the function of the electrical device 100. In other embodiments, the heating element 70 is an electrical component of the electrical device 100 to provide power to ensure the function of the heat generating element 20. The heating element 70 is easy to generate heat when working, and it needs to be cooled to ensure its working efficiency. However, since at least part of the heating element 70 is easily damaged by contamination by dust, impurities, etc., when using airflow generators such as blowers and fans to dissipate heat, the blowers, fans, etc. are easy to bring in dust, impurities, etc. to pollute the heating element 70 when working. Therefore, the dustproof function of the heating element 70 needs to be improved.

[0087] It is worth noting that the heating element 70 can be a functional module of the electrical device 100 or an electrical component of the electrical device 100; the heat generating element 20 can be a functional module of the electrical device 100 or an electrical component of the electrical device 100. That is, the heating element 70 and the heat generating element 20 are both two parts in the electrical device 100 that are prone to heat generation. In the embodiment of the present application, in order to clearly illustrate the heat dissipation effect of the diverter and the radiator on the parts that are prone to heat generation in different areas, the two terms heating element 70 and heat generating element 20 are used. The heating element 70 and the heat generating element 20 may be related or not related. The embodiment of the present application does not limit the specific forms of the heating element 70 and the heat generating element 20.

[0088] The third airflow generator 40c is used to generate airflow. In some embodiments, the third airflow generator 40c can be a blower or a fan. The radiator 80 is provided with a second heat dissipation channel 80s, the suction end of the third airflow generator 40c and the blowing end of the third airflow generator 40c are arranged opposite to each other, and the blowing end of the third airflow generator 40c faces the radiator 80 and is connected to the second heat dissipation channel 80s.

[0089] It can be understood that the third airflow generator 40c is used to drive the airflow in the radiator 80 to flow along the second heat dissipation channel 80s and to dissipate from the heat dissipation hole 10s, thereby improving the heat dissipation efficiency of the radiator 80 to the heating element 70. In the embodiment of the present application, the heating element 70 is located in the first receiving cavity 101s and is arranged between the box body 50 and the partition 10m, and the radiator 80 and the third airflow generator 40c are located in the second receiving cavity 103s, that is, the heating element 70 and the third airflow generator 40c are arranged in two different areas, please refer to Figure 4 The heat transfer path C3 and Figure 8In the airflow passage C4, on the one hand, the heat generated by the heating element 70 can be transferred to the radiator 80 of the second receiving chamber 103s through the partition 10m, and then blown away by the third airflow generator 40c and dissipated from the radiator 80 of the shell 10, thereby realizing external heat dissipation and cooling of the heating element 70; on the other hand, since the heating element 70 and the third airflow generator 40c are arranged in two different areas, the dust, impurities, etc. brought in by the third airflow generator 40c during operation are located in the second receiving chamber 103s, and there is no pollution to the heating element 70 located in the first receiving chamber 101s, so the heating element 70 is not easily damaged and has a long service life.

[0090] In some embodiments, see Figure 8 The number of the second heat dissipation channels 80s of the radiator 80 is multiple, and the radiator 80 includes multiple second heat dissipation teeth 801 arranged at intervals, and a second heat dissipation channel 80s is formed between every two adjacent second heat dissipation teeth 801.

[0091] In some embodiments, the plurality of second heat dissipation teeth 801 are arranged at intervals along the third direction D3, and the plurality of second heat dissipation channels 80s formed between the plurality of second heat dissipation teeth 801 are arranged at intervals along the third direction D3. Figure 4 The heat transfer path C3 and Figure 8 In the air flow passage C4, the heat generated by the heating element 70 is transferred to the radiator 80 through the partition 10m along the first direction D1, enters the second heat dissipation channel 80s, and is then blown out by the third air flow generator 40c, thereby cooling the heating element 70.

[0092] For heat dissipation of the heat generating element 20 and the heat generating element 70, in some embodiments, please refer to Figure 8 , the first heat dissipation channel 30s of the diverter 30 and the second heat dissipation channel 80s of the radiator 80 are arranged in parallel; the direction of the blowing end of the second airflow generator 40b is the same as the direction of the blowing end of the third airflow generator 40c. With this arrangement, the airflow of the diverter 30 and the airflow of the radiator 80 in the second receiving chamber 103s are in the same flow direction, so no resistance is formed between them and the impurities between them do not interact with each other, so that the heat dissipation effect of the diverter 30 and the radiator 80 is good, and the dust prevention effect on the heat generating element 20 and the heating element 70 is good.

[0093] In addition, since the embodiment of the present application realizes internal circulation and external heat dissipation and cooling of the heat generated by the heat-generating component 20 through the diverter 30, and the heat generated by the heating component 70 is externally dissipated and cooled through the radiator 80, that is, the two different heating modules are separately cooled through two different heat dissipation methods, and their respective heat dissipation efficiency is high.

[0094] Please also refer to Figure 3 , Figure 4 and Figure 8 In the embodiment of the present application, the heat generated by the heat-generating component 20 is internally circulated and externally dissipated and cooled through the diverter 30. When the external circulation and cooling are performed, the other end of the diverter 30 is located in the second receiving chamber 103s of the shell 10. The embodiment of the present application also realizes external heat dissipation and cooling of the heating component 70 through the radiator 80. The radiator 80 is also arranged in the second receiving chamber 103s of the shell 10, that is, the heat-generating component 20 and the heating component 70 share the second receiving chamber 103s of the shell 10 when dissipating heat, so that the internal space of the electrical device 100 can be fully utilized, and the overall external size of the electrical device 100 is small.

[0095] In addition, in some embodiments, see Figure 4 The heat generating element 20 is arranged in the box body 50, the box body 50 is fixed to the bellows 60, the bellows 60 is fixed to the partition 10m, and the heating element 70 is arranged on the partition 10m. There is a first gap 50g1 between the box body 50 and the heating element 70. After the heat generated by the heat generating element 20 is transferred from the box body 50 to the first accommodating cavity 101s, since the heat generating element 20 and the heating element 70 in the box body 50 are arranged at a distance, the heat generated by the heat generating element 20 has little effect on the heating element 70.

[0096] For mounting plate 90a above, see Figure 4 The mounting plate 90a is connected to the upper cover 101 of the housing 10, and the mounting plate 90a is received in the first receiving cavity 101s. The mounting plate 90a is used for component installation. By providing the mounting plate 90a, it is convenient to install the housing 10 with external devices or other components of the electrical device 100.

[0097] In some embodiments, the mounting plate 90a and the side of the box body 50 facing away from the partition 10m have a second gap 50g2. Through the second gap 50g2, the second gap 50g2 can be used to accommodate a part of the component installed on the mounting plate 90a, so that on the one hand, it can adapt to the size requirements of the component installed on the mounting plate 90a. On the other hand, the heat generated by the heat generating part 20 in the box body 50 is not easy to affect the components installed on the mounting plate 90a. On the other hand, when installing the equipment from the outside of the shell 10, for example, by tightening screws or riveting rivets, the distance between the screws, rivets and the box body 50 is long, which is not easy to puncture the box body 50, and is not easy to further damage the heat generating part 20 in the box body 50.

[0098] For the above-mentioned housing 10 and connecting plate 90b, please refer to Fig. 9The side of the lower cover 103 of the shell 10 facing away from the partition 10m is recessed toward the partition 10m to form a receiving groove 10p, and the connecting plate 90b is arranged in the receiving groove 10p. The connecting plate 90b is used to connect the shell 10 with external equipment. For example, a certain installation thickness can be provided through the connecting plate 90b, thereby facilitating the installation of external equipment, such as a tripod 01 and the shell 10.

[0099] For the above-mentioned housing 10 and adapter plate 90c, please refer to Fig.10 The adapter plate 90c is used to connect the housing 10 with external equipment, for example, the housing 10 with the crossbeam frame 02 of the automobile roof.

[0100] In some embodiments, an elastic member 90d is disposed on the adapter plate 90c, and the elastic member 90d is detachably connected to the lower cover 103, thereby facilitating the connection between the adapter plate 90c and the housing 10.

[0101] In some embodiments, the elastic member 90d includes a first connecting block 90d1, a second connecting block 90d2, a first elastic sheet 90d3 and a second elastic sheet 90d4. The first connecting block 90d1 and the second connecting block 90d2 are spaced apart from each other. The first elastic sheet 90d3 and the second elastic sheet 90d4 are relatively arranged at the two ends of the first connecting block 90d1 and the second connecting block 90d2. One end of the first elastic sheet 90d3 is connected to the first connecting block 90d1, and the other end of the first elastic sheet 90d3 is connected to the second connecting block 90d2. One end of the second elastic sheet 90d4 is connected to the first connecting block 90d1, and the other end of the second elastic sheet 90d4 is connected to the second connecting block 90d2. The first connecting block 90d1 is connected to the adapter plate 90c, and the second connecting block 90d2 is detachably connected to the shell 10. Through the elastic member 90d, after the electrical device 100 is connected to an external device, even if the external device vibrates, its force toward the electrical device 100 is buffered by the first elastic piece 90d3 and the second elastic piece 90d4 of the elastic member 90d, and the electrical device 100 is not easily damaged.

[0102] In some embodiments, there are multiple elastic members 90d, and the multiple elastic members 90d are distributed on the adapter plate 90c.

[0103] In some embodiments, the adapter plate 90c includes a main body 90c1, a first inclined portion 90c2, a second inclined portion 90c3, a first connecting portion 90c4 and a second connecting portion 90c5, the elastic member 90d is arranged on the main body 90c1, one end of the first inclined portion 90c2 is connected to one end of the main body 90c1, the other end of the first inclined portion 90c2 is connected to the first connecting portion 90c4, the first connecting portion 90c4 is used to connect one end of the crossbeam frame 02 of the automobile roof, one end of the second inclined portion 90c3 is connected to the other end of the main body 90c1, the other end of the second inclined portion 90c3 is connected to the second connecting portion 90c5, and the second connecting portion 90c5 is used to connect the other end of the crossbeam frame 02 of the automobile roof. With this arrangement, the first inclined portion 90c2, the main body 90c1 and the second inclined portion 90c3 are partially hollow. Therefore, even if the car vibrates, the force acting toward the electrical device 100 is buffered by the main body 90c1, the first inclined portion 90c2 and the second inclined portion 90c3, and the electrical device 100 is not easily damaged.

[0104] It is worth noting that, in some embodiments, the cross beam frame 02 of the automobile roof is arranged in pairs, the first connecting parts 90c4 are arranged in pairs, and the second connecting parts 90c5 are arranged in pairs. The first connecting part 90c4 is used to connect one end of the cross beam frame 02 of the automobile roof, and the second connecting part 90c5 is used to connect the other end of the cross beam frame 02 of the automobile roof.

[0105] In the embodiment of the present application, the heat generated by the heat generating element 20 is internally circulated and externally dissipated and cooled by the diverter 30, and the heat generated by the heat generating element 70 is externally dissipated and cooled by the radiator 80, that is, two different heat dissipation methods are used to dissipate heat for two different heat generating modules separately, and each of them has a strong heat dissipation capacity and high heat dissipation efficiency. In addition, since the two heat dissipation methods share the second receiving cavity 103s of the housing 10 to dissipate heat from the heat dissipation holes 10s of the housing 10, the internal space of the electrical device 100 can be fully utilized, and the overall outer dimensions of the electrical device 100 are small. In addition, in the present application, the heat generating element 20 and the heating element 70 are distributed in the first receiving cavity 101s of the shell 10, and the heat generating element 20 and the heating element 70 are waterproof and dustproof through the first receiving cavity 101s, and are connected to the outside of the shell 10 through the second receiving cavity 103s and the heat dissipation hole 10s, thereby improving the heat dissipation effect. After the dust and impurities outside the shell 10 enter the second receiving cavity 103s, their influence on the heat generating element 20 and the heating element 70 can be reduced, thereby reducing the risk of damage to the heat generating element 20 and the heating element 70 due to pollution, and improving the service life of the heat generating element 20 and the heating element 70. In addition, in the embodiment of the present application, the electrical device 100 integrates the heat generating component 20 and the heating component 70 as functional modules, and also adopts two different methods to dissipate heat for the heat generating component 20 and the heating component 70 respectively. The two do not affect each other, and their respective heat dissipation efficiency is high. The heat generating component 20 and the heating component 70 have high working efficiency and long service life; while dissipating heat, the present application arranges each component in different areas, thereby achieving waterproof and dustproof of the heat generating component 20 and the heating component 70 and improving their service life; the present application realizes multiple functions through the reasonable layout of each component, ensures the efficient and long-term operation of the electrical device 100, and the equipment structure is compact and highly integrated.

For the specific structure and function of the electrical device 100, please refer to the above embodiment, which will not be repeated here.

[0107] The heat generating part 20 in the electrical device 100 includes a navigation induction module, which is used to lure a drone or control the navigation of the drone. For example, when a drone is used for some illegal activities, the drone can be lured or controlled by sending navigation information to the drone to ensure the safety of a certain space area.

[0108] The heating element 70 in the electrical device 100 provides power for the operation of the navigation induction device 200 . In some embodiments, the heating element 70 includes a power board and a power amplifier.

In some embodiments, the other of the two radio frequency lines 42 is used to send navigation information to the drone in the target area, such as a false GPS (Global Positioning System) signal, a GLONASS (Global Navigation Satellite System) signal, or a signal of other navigation satellite systems.

[0111] In some embodiments, see Fig.12 A connecting rod 10q is connected to the outer side of the housing 10, and one end of the connecting rod 10q away from the housing 10 is screwed to the body 41 of the antenna 4. One end of the RF line 42 is screwed to the body 41, and the other end of the RF line 42 is screwed to the housing 10.

[0112] In some embodiments, one end of the connecting rod 10q away from the housing 10 is sealed to the body 41 through a seal 1. One end of the RF line 42 is sealed to the body 41 through a seal 1, and the other end of the RF line 42 is sealed to the housing 10 through a seal 1, thereby achieving waterproofing of the device.

[0113] The two radio frequency line lightning arresters 7 are both arranged in the first receiving cavity 101s. When the electrical device 100 includes a mounting plate 90a, the two radio frequency line lightning arresters 7 are mounted on the mounting plate 90a, and the two radio frequency line lightning arresters 7 are respectively connected to the two radio frequency lines 42. If lightning enters the electrical device 100 through the antenna 4, it will be cut off by the two radio frequency lines 42, preventing the various components in the navigation guidance device 200 including the heat generating component 20 and the heating component 70 from being destroyed by lightning.

[0114] The grounding wire 8 is connected to the housing 10. If the housing 10 is struck by lightning, the lightning current will be conducted to the ground through the grounding wire 8, thereby protecting the navigation guidance device 200 from lightning.
