Description

Technical Field

[0001] The utility model belongs to the technical field of switch cabinets, and particularly relates to an embedded heat dissipation device. Background Art

[0002] A switch cabinet is an electrical device, and its main function is to open, close, control, and protect electrical equipment during the processes of power generation, power transmission, power distribution, and power conversion in the power system. During the use of the switch cabinet, its internal mechanism continuously generates heat during operation. The heat dissipation effect inside the switch cabinet is poor, resulting in too high a temperature inside the switch cabinet. The internal mechanism components are prone to damage when operating in a high-temperature environment for a long time, reducing the service life. In the prior art, there has been a technology of setting a heat dissipation fan inside the switch cabinet. However, the circuit of this heat dissipation fan shares the same set of circuits with the switch cabinet, resulting in the need to cut off the power supply for the entire switch cabinet when the heat dissipation fan needs to be maintained, which does not meet the actual requirements.

[0040] Combined with Figures 1 to 6 As shown, the present utility model provides an embedded heat dissipation device, which includes: a housing 20, which is provided with an air inlet 211, an air outlet 212, and a receiving cavity 210, and the receiving cavity is communicated with the air inlet and the air outlet; a fan 30, which is arranged in the receiving cavity and corresponding to the air inlet, and the fan is provided with an independent circuit on-off switch; a cover plate 40, which is detachably arranged at the air inlet; and a ventilation area is provided on the cover plate.

[0041] Compared with the prior art, the present application innovatively designs an embedded heat dissipation device, which is installed in the switch cabinet 50 in an embedded manner, and uses the fan 30 to work to send air to the switch cabinet 50, driving the air flow in the switch cabinet 50 to realize heat dissipation and cooling of the internal mechanism components of the switch cabinet 50; moreover, the fan 30 is provided with an independent circuit on-off switch. During maintenance, by powering off the fan 30 and removing the cover plate 40, the fan 30 can be repaired and maintained, and there is no need to power off the switch cabinet 50 during the maintenance process, avoiding local power outage in the power consumption area.

[0042] Specifically, the embedded heat dissipation device of the present application is used in conjunction with the switchgear 50. An opening 110 is provided at the lower side of the front panel of the switchgear 50. The embedded heat dissipation device is installed and connected to the opening so that the fan 30 is embedded inside the switchgear 50. During operation, the fan 30 is powered on under the closing action of an independent circuit on-off switch. The air outside the switchgear 50 enters the accommodation cavity 210 from the ventilation area and forms an air flow under the action of the fan 30, which is blown into the switchgear 50 for heat dissipation treatment. During maintenance, the fan 30 is powered off under the opening action of the independent circuit on-off switch, and maintenance personnel can perform maintenance on the fan 30 by removing the cover plate 40.

[0043] It should be noted that in other embodiments, the embedded heat dissipation device can be used in conjunction with the existing switchgear 50, but the existing switchgear 50 needs to be correspondingly modified, such as cutting out the opening. The position of the opening can be set on other sides of the switchgear 50, and specifically depends on the distribution of the internal mechanism components in the switchgear 50, and it is necessary to ensure that there is enough space to accommodate the embedded heat dissipation device.

[0044] Furthermore, the embedded heat dissipation device is insulated from the switchgear to ensure that maintenance personnel are completely isolated from live parts and ensure the safety of maintenance personnel during maintenance. During maintenance, only the circuit on-off switch of the fan 30 needs to be disconnected to complete the maintenance and replacement of the fan 30 at any time.

[0045] In one embodiment, a first mounting hole 4111 is provided on the cover plate 40; a second mounting hole 201 is provided on the housing, and the second mounting hole corresponds to the first mounting hole; the cover plate is connected to the housing by bolts passing through the first mounting hole and the second mounting hole in sequence.

The cover plate 40 is installed on the front panel 10 by tightening the bolts, and the cover plate 40 is removed by loosening the bolts.

[0047] In one embodiment, a ventilation filter plate 410 is provided in the ventilation area to perform dust prevention treatment on the air entering the switchgear 50 and prevent dust and dirt from accumulating in the switchgear 50.

[0048] In one embodiment, a third mounting hole 202 is provided on the housing, and the third mounting hole corresponds to a fourth mounting hole 1111 of the switch cabinet; the switch cabinet is connected to the housing by bolts passing through the fourth mounting hole and the third mounting hole in sequence.

[0049] In one embodiment, the housing 20 includes a blower cover 213 and a blower cover mounting plate 214. An installation opening 215 is provided above the blower cover 213, and the installation opening 215 is connected to the blower cover mounting plate 214; specifically, after the front end of the lower side of the blower cover 213 is installed and connected to the rear side surface of the front side panel 10, the front end of the blower cover mounting plate 214 is then installed and connected to the rear side surface of the front side panel 10. During the manufacturing process of the embedded heat dissipation device in this embodiment, the installation of the blower 30 can be facilitated through the cooperation of the installation opening 215 and the opening 110.

[0050] Further, the blower cover mounting plate 214 is horizontally arranged relative to the front side panel 10; the blower cover 213 includes a bending member, and the bending member successively includes a first connecting plate 2131, a second connecting plate, and a third connecting plate from top to bottom.

[0051] In one embodiment, the embedded heat dissipation device further includes a mounting bracket 60. One end of the mounting bracket 60 is arranged on the blower cover 213, and the other end is installed and connected to the blower 30 to form a mounting connection position. The mounting bracket 60 is used to realize the assembly of the blower 30 and the blower cover 213. During maintenance, one end of the mounting bracket 60 can be directly detached from the blower cover 213 to realize the disassembly and replacement of the blower 30, avoiding detaching the entire embedded heat dissipation device from the switch cabinet 50.

[0052] In one embodiment, the mounting connection position is exposed in front of the embedded heat dissipation device by the air inlet; the mounting connection position is exposed above the embedded heat dissipation device by the installation opening 215, facilitating the installation operation of the blower 30 by workers.
