[0038] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0040] In the present invention, unless otherwise specified, directional words such as "up" and "down" are usually used in reference to the directions shown in the drawings, or in reference to the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "left" and "right" are usually used in reference to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0041] In order to improve the influence of heat generated by the transformer in an open state in the prior art on peripheral equipment and further enhance the heat dissipation capacity of the transformer and the integrated machine, the present application provides a heat dissipation guide mechanism and a cabinet having the same.

[0042] In one embodiment, if Figures 1 to 6As shown, the heat dissipation and air guiding mechanism is used to dissipate heat for the electrical device 10, and the heat dissipation and air guiding mechanism includes a first enclosure structure 20 and a second enclosure structure 30. The first enclosure structure 20 has a first accommodating cavity 22, and the first accommodating cavity 22 has a first opening 21, and the first accommodating cavity 22 is used to install the electrical device 10. The second enclosure structure 30 is located above the first enclosure structure 20 and has a air guiding cavity 31, and the first accommodating cavity 22 is connected to the air guiding cavity 31 through the first opening 21.

[0043] By applying the technical solution of this embodiment, the above-mentioned position setting of the second enclosure structure 30 can play the role of a "chimney", and the heat flow generated by the electrical device 10 (such as a transformer) is guided by the diversion function of the chimney. After the electrical device 10 (such as a transformer) is installed in the first accommodating cavity 22, the heat dissipated from its surface is dissipated through the first accommodating cavity 22, the first opening 21 and the diversion cavity 31 in sequence, and the heat is prevented from diffusing to the surroundings and affecting the normal operation of other equipment, thereby realizing the heat dissipation function of the heat dissipation diversion mechanism, so as to improve the influence of the heat generated by the transformer in an open state on the surrounding equipment in the prior art, and further improve the heat dissipation capacity of the transformer and the integrated machine.

[0044] In this embodiment, the above-mentioned arrangement of the second enclosure structure 30 can form a chimney effect, which plays a guiding role in the heat dissipation of the transformer and is beneficial to the heat dissipation of the transformer.

[0045] In this embodiment, the height of the second enclosure structure 30 can be set according to usage requirements to increase the heat conduction length and prevent the heat outlet from being too close to other equipment and thus being sucked into the equipment.

[0046] like Figure 2 , Figure 5 as well as Figure 6 As shown, the first enclosure structure 20 also has a second accommodating cavity 23, which is independently arranged from the first accommodating cavity 22. In this way, the second accommodating cavity 23 is used to accommodate other equipment. Since the first accommodating cavity 22 and the second accommodating cavity 23 are independently arranged, the speed of heat diffusion through the cavity walls of the first accommodating cavity 22 and the second accommodating cavity 23 is slowed down, thereby preventing other equipment placed in the second accommodating cavity 23 from being affected by the heat, thereby ensuring the normal operation of the equipment.

[0047] Optionally, there is one second accommodating cavity 23; or, there are at least two second accommodating cavities 23, and at least two second accommodating cavities 23 are arranged around the first accommodating cavity 22. In this way, the above arrangement makes the number of second accommodating cavities 23 more flexible to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff. At the same time, multiple second accommodating cavities can accommodate multiple peripheral devices to improve the integration level of the integrated all-in-one machine.

[0048] In this embodiment, there are two second accommodating cavities 23, and the two second accommodating cavities 23 are respectively located on both sides of the first accommodating cavity 22, so that the structure of the first enclosure structure 20 is simpler and easier to process and realize.

[0049] It should be noted that the number of the second accommodating chambers 23 is not limited thereto, and can be selected according to working conditions and usage requirements. Optionally, the number of the second accommodating chambers 23 is three, four, five, or more.

[0050] Optionally, the height of the first accommodating cavity 22 is greater than or equal to the height of the electrical device 10 .

[0051] In this embodiment, the height of the first accommodating cavity 22 is greater than the height of the electrical device 10. Thus, the height setting of the first accommodating cavity 22 ensures that the first enclosure structure 20 can enclose the electrical device 10 on all sides to prevent heat from diffusing from all sides and ensure that all heat is discharged from the guide cavity 31.

[0052] In other embodiments not shown in the drawings, the height of the first accommodating cavity is equal to the height of the electrical device.

[0053] In this embodiment, the orthographic projection of the first opening 21 on the flow guiding cavity 31 is inside the flow guiding cavity 31. In this way, the above arrangement ensures that the heat discharged through the first opening 21 can be discharged from the flow guiding cavity 31 in a timely manner, and prevents the heat from accumulating at the connection point between the first opening 21 and the flow guiding cavity 31 and affecting the heat dissipation efficiency of the heat dissipation and flow guiding mechanism.

[0054] It should be noted that the orthographic projection of the first opening 21 on the guide cavity 31 in the guide cavity 31 here includes an implementation manner in which the orthographic projection of the first opening 21 on the guide cavity 31 is on the cavity wall of the guide cavity 31 .

[0055] like Figure 1 , Figure 2 as well as Figure 6 As shown, the first enclosure structure 20 also has a second opening 24, at least part of which is arranged opposite to and communicates with the vent of the electrical device 10; the second opening 24 is located below the first opening 21. In this way, during the operation of the electrical device 10, air in the environment can enter the vent of the electrical device 10 through the second opening 24 to ensure that the electrical device 10 can operate normally. At the same time, the second opening 24 located below the first opening 21 can prevent the hot air flow discharged from the first opening 21 from entering the electrical device 10 through the second opening 24.

[0056] like Figure 4 and Figure 5As shown, the heat dissipation and air guiding mechanism further includes a shielding structure 40. The shielding structure 40 can be movably arranged at least at a portion of the second opening 24 to shield or avoid the portion of the second opening 24. In this way, when the second opening 24 is needed to let in air, the shielding structure 40 is controlled to avoid the second opening 24 to ensure that the gas in the environment can enter the vent of the electrical device 10 through the second opening 24. When the electrical device 10 is in a shutdown state, the shielding structure 40 can be controlled to block the second opening 24, thereby preventing impurities from entering the heat dissipation and air guiding mechanism, thereby playing a dust-proof role.

[0057] In this embodiment, the shielding structure 40 shields all the second openings 24 and is in a fully shielding state to prevent heat flow from entering the air inlet of the device placed in the second accommodating cavity 23 .

[0058] Optionally, the first enclosure structure 20 and the second enclosure structure 30 are detachably connected or integrally formed. In this embodiment, the first enclosure structure 20 and the second enclosure structure 30 are detachably connected, and the heat dissipation and air flow guiding mechanism has a transportation state in which the first enclosure structure 20 and the second enclosure structure 30 are connected by a hinge, and a use state in which the first enclosure structure 20 and the second enclosure structure 30 are connected by a fastener. In this way, when the heat dissipation and air flow guiding mechanism needs to be transported and transferred, the first enclosure structure 20 and the second enclosure structure 30 are connected by a hinge to be in the transportation state; when it is transported to the destination and needs to be used, the first enclosure structure 20 and the second enclosure structure 30 are connected by a fastener to be in the use state.

[0059] Specifically, the heat dissipation and air guiding mechanism has two states, namely a transportation state and a use state, so as to transport it.

[0060] Optionally, the fasteners are bolts and nuts.

[0061] like Figure 2 as well as Figure 6 As shown, the first enclosure structure 20 includes an enclosure plate and a partition plate 29. The enclosure plate includes a first plate body 25, a second plate body 26, a third plate body 27 and a fourth plate body 28 connected end to end. The first plate body 25, the second plate body 26, the third plate body 27 and the fourth plate body 28 surround and form an enclosure plate cavity. The partition plate 29 is arranged in the enclosure plate cavity to separate the enclosure plate cavity into a first accommodating cavity 22 and a second accommodating cavity 23. Among them, the second opening 24 is arranged on the enclosure plate. In this way, the above arrangement makes the structure of the first enclosure structure 20 simpler, easier to process and realize, and reduces the processing cost and difficulty of the first enclosure structure 20.

[0062] Optionally, there is one second opening 24; or, there are multiple second openings 24, and the multiple second openings 24 are arranged at intervals along at least one direction of the first direction h, the second direction w, and the third direction L. In this way, the above arrangement makes the number selection and arrangement of the second openings 24 more flexible to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff. At the same time, multiple second openings 24 can increase the air intake of the electrical device 10 to meet the air intake requirements of the electrical device 10.

[0063] In this embodiment, there are two groups of second openings 24, and the two groups of second openings 24 are arranged at intervals along the second direction w.
