[0036] Embodiment:
[0037] This embodiment provides a heat dissipation component for a switch cabinet to solve the technical problem that the heat dissipation opening in the existing switch cabinet is prone to water ingress. The heat dissipation component for the switch cabinet includes a housing 1, a first part 2, a heat dissipation fan 3 and a second part 4, where:
[0038] The housing 1 has a heat dissipation opening 11 arranged along the first direction. The heat dissipation opening 11 can be located at the top end of the housing 1 or on the side wall of the housing 1. In this way, through the arrangement of the heat dissipation opening 11, the gas inside and outside the housing 1 is exchanged, thereby achieving the purpose of heat dissipation.
[0039] The first part 2 is installed on the housing 1 and is located at the heat dissipation opening 11. The first part 2 is communicated with the heat dissipation opening 11. Optionally, the first part 2 is a first ventilation duct, and the first ventilation duct is arranged along a first direction, that is, the first ventilation duct is coaxially arranged with the heat dissipation opening 11.
[0040] The cooling fan 3 is installed in the first part 2. The cooling fan 3 is coaxially arranged with the first ventilation duct. By arranging the cooling fan 3, the flow of gas is accelerated, thereby improving the heat dissipation efficiency.
[0041] One end of the second part 4 is rotatably installed at the other end of the first part 2 and is communicated with the first part 2. And there is an included angle α between the first part 2 and the second part 4. Optionally, the second part 4 is a second ventilation duct, that is, there is an included angle α between the axis of the first ventilation duct and the axis of the second ventilation duct. In this way, there is an included angle between the plane where the heat dissipation opening 11 is located and the plane where the end of the second ventilation duct away from the first ventilation duct is located. And the rotatably installed second part 4 facilitates adjusting the orientation of the second ventilation duct, further reducing the probability of rainwater entering the housing 1.
[0042] With the above structure, when using the heat dissipation component for the switch cabinet provided by the present utility model, through the setting of the heat dissipation opening 11, the gas inside and outside the housing 1 is exchanged to achieve the purpose of heat dissipation. At the same time, through the setting of the cooling fan 3, the speed of air flow is accelerated, further improving the heat dissipation efficiency. And through the setting of the included angle α between the first part 2 and the second part 4, the plane where the heat dissipation opening 11 is located and the plane where the end of the second part 4 away from the first part 2 is located are intersecting. When it rains outdoors, if the heat dissipation opening 11 is located at the top of the housing 1, the second part 4 is rotated by rotating the second part 4 so that the orientation of the end of the second part 4 away from the first part 2 is opposite to the direction of raindrop fall, thereby reducing the probability of rainwater entering the housing 1; if the heat dissipation opening 11 is located on the side of the housing 1, the second part 4 is rotated so that the end of the second part 4 away from the first part 2 is arranged downward, thereby reducing the probability of rainwater entering the housing 1. Therefore, through the setting of the included angle α between the first part 2 and the second part 4, the heat dissipation component for the switch cabinet provided by the present utility model reduces the probability of rainwater entering the switch cabinet through the heat dissipation opening 11, thereby reducing the probability of the equipment being affected.
[0043] An optional implementation manner of this embodiment is as follows: It further includes a connecting piece 5. One end is detachably installed on the housing 1 and is located at the heat dissipation opening 11. One end of the first part 2 is rotatably installed at the other end of the connecting piece 5. In this way, through the detachably installed connecting piece 5, it is convenient to install the first part 2 and the second part 4 on the housing 1 or disassemble them from the housing 1, thereby facilitating the replacement of damaged parts therein.
[0044] Optionally, the connecting member 5 is mounted on the housing 1 by bolts. The connecting member 5 mounted by bolts is more convenient for disassembly and assembly and has high replaceability.
[0045] An alternative implementation of this embodiment is as follows: It further includes a plurality of spring balls 6. A plurality of mounting grooves are formed on the outer side wall of the connecting member 5. The plurality of mounting grooves are uniformly arranged along the circumferential direction of the connecting member 5. One ends of the plurality of spring balls 6 are respectively mounted in the plurality of mounting grooves. An arc-shaped groove 21 is formed on the inner side wall of the first part 2. The other end of any one of the plurality of spring balls 6 extends out of the corresponding mounting groove and abuts in the arc-shaped groove 21. Through the cooperation of the spring ball 6 and the arc-shaped groove 21, when any one of the spring balls 6 abuts in the arc-shaped groove 21, the remaining spring balls 6 are all in a compressed state and abut against the inner side wall of the first part 2. When it is necessary to change the orientation of the second part 4, first rotate the first part 2 so that the spring ball 6 abutting in the arc-shaped groove 21 is compressed until the other end of the spring ball 6 disengages from the arc-shaped groove 21. Continue to rotate the first part 2 until the arc-shaped groove 21 rotates to the next spring ball 6. At this time, the corresponding spring ball 6 returns and abuts in the arc-shaped groove 21, thereby fixing the first part 2 and reducing the probability that the second part 4 is blown by the wind and thus changes the orientation of the second part 4. For example, if the other end of the second part 4 is not adjusted to the required orientation, continue to rotate the first part 2 until it is done.
[0046] Optionally, it further includes an annular protrusion 22 provided on the inner side wall of the first part 2. An annular groove 52 adapted to the annular protrusion 22 is formed on the outer side wall of the connecting member 5. The annular protrusion 22 is inserted into the annular groove 52. In this way, through the cooperation of the annular protrusion 22 and the annular groove 52, it is avoided that the first part 2 is disengaged from the connecting member 5 when the first part 2 is rotated.
[0047] An alternative implementation of this embodiment is as follows: The number of the arc-shaped grooves 21 is multiple, and the multiple arc-shaped grooves 21 are uniformly arranged along the circumferential direction of the first part 2. In this way, through the arrangement of the multiple arc-shaped grooves 21, it is more convenient to adjust the orientation of the second part 4.
[0048] Optionally, the multiple arc-shaped grooves 21 are arranged in one-to-one correspondence with the multiple mounting grooves. In this way, when the first part 2 and the connecting member 5 are relatively fixed, each spring ball 6 is in an extended state, avoiding the spring ball 6 from being in a compressed state all the time and causing the spring ball 6 to fail.
[0049] Optionally, a connecting sliding groove 23 is provided between adjacent two arc-shaped grooves 21. In this way, it is avoided that the first part 2 is disengaged from the connecting member 5 when the first part 2 is rotated.
[0050] An alternative implementation of this embodiment is as follows: The range of the included angle α is: 90° ≤ α ≤ 120°. If the angle is too large, the component will fail; if the angle is too small, air flow will be difficult.
[0051] An alternative implementation of this embodiment is as follows: It further includes a filter screen 7 installed in the second part 4. By providing the filter screen 7, the probability of dust in the air entering the housing 1 is reduced.
[0052] The specific implementation manners described above further elaborate on the purpose, technical solutions, and beneficial effects of the present utility model. It should be understood that the above are only specific implementation manners of the present utility model and are not used to limit the protection scope of the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
