The following detailed description of implementations of the present application is provided in conjunction with specific embodiments.
As shown in fig. 1-2, the embodiment of the present application provides a cooling device 3, which includes a heat dissipation metal plate 33 having a heat dissipation cavity 334, an air inlet fan 31 connected to the heat dissipation metal plate 33, and an air outlet fan 32 connected to the heat dissipation metal plate 33; the heat dissipation metal plate 33 is provided with an air inlet 3311 and an air outlet 3321 which are communicated with the heat dissipation cavity 334; the air inlet fan 31 is hermetically connected to the heat dissipation metal plate 33 at the air inlet 3311, and the air outlet fan 32 is hermetically connected to the heat dissipation metal plate 33 at the air outlet 3321.
In the embodiment of the present application, please refer to fig. 3-6 synchronously, the heat dissipation metal plate 33 of the cooling device 3 may be installed in the accommodating cavity 11 of the sealed vehicle body 1 of the outdoor inspection vehicle, and the air inlet fan 31 and the air outlet fan 32 are communicated with the outside of the accommodating cavity 11; the heat dissipation metal plate 33 is in heat conduction contact with a heat source, and the heat source can be specifically a component with the largest heat productivity such as a motor module 2 in an outdoor inspection vehicle; the heat dissipation and cooling process of the cooling device 3 is as follows: the air intake fan 31 introduces external normal temperature air into the heat dissipation cavity 334 of the heat dissipation metal plate 33 through the air intake 3311, and moves a distance in the heat dissipation cavity 334 and then leaves the heat dissipation metal plate 33 from the air outlet 3321; because the heat dissipation metal plate 33 is in heat conduction contact with the motor module 2, when the air moves in the heat dissipation cavity 334 of the heat dissipation metal plate 33, the heat transferred to the heat dissipation metal plate 33 by the motor module 2 can be taken away, and further the heat dissipation of the motor module 2 is realized; because the heat dissipation metal plate 33 is located in the accommodating cavity 11 of the sealed vehicle body 1, heat generated by other heat generating components in the accommodating cavity 11 can be transferred to the heat dissipation metal plate 33 through the air inside the accommodating cavity 11, thereby realizing heat dissipation of other components in the accommodating cavity 11.
Because the air inlet fan 31 is hermetically connected with the heat dissipation metal plate 33 at the air inlet 3311 and the air outlet fan 32 is hermetically connected with the heat dissipation metal plate 33 at the air outlet 3321, the heat dissipation channel formed by the air inlet 3311, the heat dissipation cavity 334 and the air outlet 3321 is an independent system; when the cooling device 3 is installed on mechanical equipment such as an outdoor inspection vehicle (hereinafter, the outdoor inspection vehicle is taken as an example for explanation), the heat dissipation metal plate 33 is in contact with a heat source of the outdoor inspection vehicle, but the heat dissipation air duct of the cooling device 3 is isolated from the inside of the outdoor inspection vehicle, so that dust and water mist cannot be brought into the outdoor inspection vehicle when the cooling device 3 is used, a dust screen and waterproof asbestos do not need to be used in combination and cover the air inlet fan 31 and the air outlet fan 32, the limitation of air speed flowing is avoided, the heat exchange speed is ensured, and the heat dissipation and cooling effects of the mechanical equipment with higher waterproof and dustproof requirements are further ensured.
Further, referring to fig. 3, as another embodiment of the cooling device 3 provided in the present application, at least one first air guiding plate 34 is disposed in the heat dissipation cavity 334; the first air guiding plate 34 is provided with a first air guiding groove 341. The first air guiding groove 341 on the first air guiding plate 34 enables the air in the heat dissipation cavity 334 to move along a preset direction and area, that is, the air is concentrated at the first air guiding groove 341 and moves along the length direction of the first air guiding groove 341, so that the first air guiding groove 341 can be corresponding to the maximum heat source motor module 2 of the outdoor inspection vehicle during use, and therefore the air in the heat dissipation cavity 334 is concentrated at the motor module 2 and the heat generated by the motor module 2 is dispersed by the metal plate 33.
The heat is dissipated in a mode that the heat dissipation air is concentrated in the main heating source, so that the heat dissipation effect is improved; meanwhile, as the heat of the main heating source (the motor module 2 is taken as an example below) is taken away in time, the rapid temperature rise of other parts of the mechanical equipment due to the influence of the heat generated by the main heating source is avoided. For example, when mechanical equipment such as an outdoor inspection vehicle is provided with the sealed vehicle body 1 in order to ensure sufficient waterproof and dustproof performance, the heat of the motor module 2 is taken away in time, and the rise of the temperature inside the sealed vehicle body 1 can be effectively avoided.
Further, referring to fig. 3, as another embodiment of the cooling device 3 provided in the present application, the first air guiding plate 34 is further provided with a second air guiding groove 342; the width of the second air guiding groove 342 is greater than that of the first air guiding groove 341. The width of the first air guiding groove 341 is the smallest, so that the speed of air flowing through the first air guiding groove 341 is the fastest, the speed of air flow exchange at the area is accelerated, and the heat dissipation efficiency of the motor module 2 is ensured. The main heating source in the outdoor inspection vehicle is the motor module 2, and can also be other parts which generate heat more seriously, other parts which generate heat more seriously and the second air guide groove 342 can be arranged, the airflow velocity at the second air guide groove 342 is slightly smaller than that at the first air guide groove 341, so that the airflow exchange speed is slightly smaller, but the heat dissipation and cooling effects can also be ensured for the parts which generate heat less than the motor module 2. The arrangement of the first air guide groove 341 and the second air guide groove 342 reasonably distributes the heat dissipation airflow according to the requirement, so that the heat generated by the cooled parts at all places can be discharged in time, and the temperature at all places can be well controlled. The need for total airflow is reduced relative to providing the same heat dissipating airflow throughout. Since the width of the first air guiding groove 341 is the smallest, the number of the first air guiding grooves 341 per unit area is the largest, that is, the number of the inner side walls of the first air guiding groove 341 is plural, thereby increasing the heat dissipation area.
Further, referring to fig. 3, as another embodiment of the cooling device 3 provided in the present application, a third air guiding groove 343 is further formed on the first air guiding plate 34; the width of the third wind guide groove 343 is greater than that of the first wind guide groove 341; the second wind-guiding groove 342 and the third wind-guiding groove 343 are respectively located at two opposite sides of the first wind-guiding groove 341. The width of the first air guiding groove 341 is the smallest, so that the speed of air flowing through the first air guiding groove 341 is the fastest, the speed of air flow exchange at the area is accelerated, and the heat dissipation efficiency of the motor module 2 is ensured. The main heating source in the outdoor inspection vehicle is the motor module 2, and can also be other parts which generate heat more seriously, the other parts which generate heat more seriously correspond to the second air guide groove 342 or the third air guide groove 343, and the airflow velocity at the positions of the second air guide groove 342 and the third air guide groove 343 is slightly smaller than that at the position of the first air guide groove 341, so that the airflow exchange speed is slightly smaller, but the heat dissipation and cooling effect can also be ensured for the parts which generate heat less than the motor module 2. The arrangement of the first air guide groove 341, the second air guide groove 342 and the third air guide groove 343 reasonably distributes the heat dissipation airflow according to the requirement, so that the heat generated by the cooled parts at all places can be timely discharged, and the temperature at all places can be well controlled. The need for total airflow is reduced relative to providing the same heat dissipating airflow throughout. Since the width of the first air guiding groove 341 is the smallest, the number of the first air guiding grooves 341 per unit area is the largest, that is, the number of the inner side walls of the first air guiding groove 341 is plural, thereby increasing the heat dissipation area. The motor module 2 is used as a maximum heating source to transfer heat to peripheral components thereof in a heat radiation mode, so that the second air guide groove 342 and the third air guide groove 343 are respectively positioned at two opposite sides of the first air guide groove 341, heat generated by heat radiation of the motor module 2 can be taken away in time, and the temperature rise of the peripheral components of the motor module 2 is avoided being too fast.
Further, please refer to another embodiment of the cooling device 3 provided in the present application, an inner sidewall of the third air guiding groove 343 is provided with a notch 3431. When the number of the motor modules 2 of the outdoor inspection vehicle is multiple, for example, two, the number of the first air deflectors 34 is two, one first air deflector 34 corresponds to one motor module 2, and the two first air deflectors 34 are both located in the heat dissipation metal plate 33, so that when the first air deflector 34 dissipates heat of the first motor module 2, in order to ensure that the second motor module 2 can also dissipate heat by lower-temperature air, the notch 3431 at the third air guide groove 343 at the first air deflector 34 can allow the lower-temperature air to leave the first air deflector 34 and reach the next first air deflector 34, enter the next first air guide groove 341, the second air guide groove 342, and the third air guide groove 343, and dissipate heat of the next motor module 2.
Further, referring to fig. 1 and 4, as another embodiment of the cooling device 3 provided by the present application, the heat dissipation metal plate 33 includes a first heat dissipation portion 331 connected to the air intake fan 31, a second heat dissipation portion 332 connected to the air outlet fan 32, and a heat dissipation connecting portion 333 connected between the first heat dissipation portion 331 and the second heat dissipation portion 332. Air enters the first heat dissipation part 331 through the air inlet 3311, flows through a certain heat dissipation stroke, enters the second heat dissipation part 332 through the heat dissipation connecting part 333, and then flows through a certain heat dissipation stroke in the second heat dissipation part 332 for heat dissipation; the coverage of a large area is realized in the minimum area, and the heat dissipation efficiency is improved.
Further, referring to fig. 1 and fig. 4, as another embodiment of the cooling device 3 provided in the present application, the first heat sink portion 331 and the second heat sink portion 332 are disposed opposite to each other and spaced apart from each other; one end of the first heat dissipation part 331, which is far away from the air inlet fan 31, is connected to the heat dissipation connecting part 333, and one end of the second heat dissipation part 332, which is far away from the air outlet fan 32, is connected to the heat dissipation connecting part 333. The first heat sink member 331 and the second heat sink member 332 are disposed to face each other at an interval, and may be disposed on the same horizontal plane or may be stacked at an interval in the same vertical direction.
Further, referring to fig. 1 and fig. 2, as another embodiment of the cooling device 3 provided in the present application, the number of the first wind deflectors 34 is two, wherein one of the first wind deflectors 34 is located at the first heat sink portion 331, and the other first wind deflector 34 is located at the second heat sink portion 332. When the number of the maximum heating sources such as the motor modules 2 is two, the two motor modules 2 correspond to the two first air deflectors 34 respectively, so that the air in the heat dissipation metal plate 33 is concentrated at the two first air deflectors 34 to dissipate the heat of the motor modules 2.
Further, referring to fig. 2, as another embodiment of the cooling device 3 provided in the present application, the first wind guiding groove 341 is an arc groove; the two first air deflectors 34 are arranged oppositely, and the central angle of the arc groove is 90 degrees. Because the first heat dissipation parts 331 and the second heat dissipation parts 332 are arranged opposite to each other at intervals, the first air guide grooves 341 on the two first air guide plates 34 can be positioned on the same circumference after being spliced, and the central angle of the circular arc groove (the first air guide groove 341) is 90 degrees, and the way of arranging the two first air guide plates 34 opposite to each other can ensure that the air flow with a high flow velocity at one first air guide groove 341 can smoothly reach the other first air guide groove 341, thereby avoiding the influence on the smoothness of the air flow in the heat dissipation cavity 334 due to the multiple changes of the air flow velocity.
Further, referring to fig. 3, as another embodiment of the cooling device 3 provided in the present application, a third air guiding groove 343 is further formed on the first air guiding plate 34; the width of the third wind guide groove 343 is greater than that of the first wind guide groove 341; the inner sidewall of the third wind guiding groove 343 has a notch 3431. When the number of the motor modules 2 of the outdoor inspection vehicle is multiple, for example, two, the number of the first air deflectors 34 is two, one first air deflector 34 corresponds to one motor module 2, and the two first air deflectors 34 are both located in the heat dissipation metal plate 33, so that when the first air deflector 34 dissipates heat of the first motor module 2, in order to ensure that the second motor module 2 can also dissipate heat by lower-temperature air, the notch 3431 at the third air guide groove 343 at the first air deflector 34 can allow the lower-temperature air to leave the first air deflector 34 and reach the next first air deflector 34, enter the next first air guide groove 341, the second air guide groove 342, and the third air guide groove 343, and dissipate heat of the next motor module 2.
