In some embodiments of the present utility model, the first cavity 201 is a closed cavity, which forms a closed flow channel in the cabinet 10, and the combination of the airflow driving member 22 and the first heat sink 2011 may be used to dissipate heat from the electronic device 30 in the first cavity 201. While the second chamber 202 may be provided in an open form, for example, a space outside the first chamber 201 in the cabinet 10 is provided as the second chamber 202, and at this time, since the second chamber 202 is an open space, the installation and maintenance of the electronic device 30 in the second chamber 202 can be facilitated. In addition, a door 18 may be installed on the cabinet 10, and the cabinet 10 may be opened and closed by the door 18. Specifically, in some embodiments, the door 18 may be used to open and close the second cavity 202, when the door 18 is opened, the second cavity 202 is opened, so that the installation and enclosure of the electronic device 30 in the second cavity 202 can be facilitated, and the operation state of the variable frequency cabinet 100 can be checked by the electronic device 30 in the second cavity 202, at this time, the first cavity 201 is in a closed state, so that the space in the second cavity 202 is not affected, the second cavity 202 can be maintained in an environment with low humidity and less dust, and the heat dissipation effect, the operation stability and the like of the second cavity 202 are relatively high; when the door 18 is closed, the second cavity 202 is closed, and a relatively closed environment is formed in the second cavity 202, so that the temperature of each place in the second cavity 202 can be relatively uniform under the action of natural convection or other modes, and heat dissipation of the electronic device 30 in the second cavity 202 can be realized to a certain extent.

In addition, in the present utility model, the second cavity 202 may not be provided with an air flow driving structure such as a fan, so that the electronic device 30 in the second cavity 202 will operate under the noise of the intersection, so that the noise of the frequency conversion cabinet 100 is effectively reduced, and the introduction of external high humidity air, dust-containing air flow, etc. into the second cavity 202 can be avoided, so as to prolong the service life of the electronic device 30 in the second cavity 202; of course, an air flow driving structure such as a fan may be disposed in the second cavity 202, so that sufficient heat exchange of the electronic device 30 in the second cavity 202 may be achieved, the temperature environment of the electronic device 30 in the second cavity 202 may be maintained, and the operation stability and service life of the electronic device 30 in the second cavity 202 may be improved.

The first cavity 201 in the present utility model may be configured as a linear, curved, or folded heat dissipation channel, and the heat dissipation device may take heat away by using the first heat sink 2011 under the driving action of the airflow driving member 22, for example, the heat dissipation airflow may flow in from one end of the first cavity 201 and flow out from the second end of the first cavity 201, which may adversely affect the surrounding environment, and may cause dust-containing airflow in the external environment to enter the first cavity 201 to affect the operation environment in the first cavity 201.

In addition, in the present utility model, the first heat sink 2011 is provided to remove heat in the first cavity 201, and when the heat dissipation airflow in the first cavity 201 circulates, the first heat sink 2011 can be used to remove heat of the electronic device 30 in the second cavity 202. Therefore, in order to reduce the influence on the surrounding environment during the heat dissipation process, the first cavity 201 may be configured as an annular cavity, and the air flow in the first cavity 201 is adapted to circulate to dissipate heat under the driving action of the air flow driving member 22. Through the circulation of the air flow, the temperature in the first cavity 201 can be effectively reduced, the heat dissipation of the electronic device 30 in the first cavity 201 is realized, a better temperature environment is provided for the operation of the electronic device 30 in the first cavity 201, meanwhile, the influence of the heat in the first cavity 201 on the surrounding environment can be reduced, particularly, the influence of the heat in the first cavity 201 on the electronic device 30 in the second cavity 202 can be reduced, and the stability of the whole frequency conversion cabinet 100 is improved. In addition, the first heat sink 2011 also has a condensation function, so that the humidity in the first cavity 201 can be adjusted by using the first heat sink 2011, and the humidity environment of the electronic device 30 in the first cavity 201 can be optimized.

The first chamber 201 of the present utility model may be provided as a circular ring-shaped, elliptical ring-shaped, polygonal ring-shaped or other irregularly shaped annular chamber, and the first chamber 201 of one embodiment of the present utility model will be described with reference to the accompanying drawings.

In some embodiments, at least one of wireless communication module 42 and control board 40 is disposed within first cavity 201 and laminated to a side wall of first cavity 201; or at least one of wireless communication module 42 and control board 40 is disposed within second cavity 202 and laminated to a side wall of second cavity 202.

In this manner, heat dissipation from either the first cavity 201 or the second cavity 202 to the wireless communication module 42 or the control board 40 may be achieved.

Specifically, when at least one of the wireless communication module 42 and the control board 40 is disposed in the first cavity 201 and is stacked on the side wall of the first cavity 201, the first radiator 2011 disposed in the first cavity 201 may provide cooling capacity, and when the heat in the first cavity 201 is reduced by air cooling, the first radiator 2011 may take away the heat in the air and radiate the air flow in time, so that the air flow better radiates heat with at least one of the wireless communication module 42 and the control board 40 in the first cavity 201, and the air cooling effect in the first cavity 201 is effectively improved. The heat exchange between the first radiator 2011 and at least one of the wireless communication module 42 and the control board 40 in the first cavity 201 is realized by air flow, and the temperature in the first cavity 201 is reduced by air cooling. Airflow driver 22 may be configured to drive airflow within first cavity 201 to form a heat sink airflow that may be configured to flow through wireless communication module 42 and control board 40 within first cavity 201 and first heat sink 2011. When the air flow flows through the first radiator 2011, heat in the air flow can be exchanged to the first radiator 2011 to reduce the temperature of the air flow, and cold of the first radiator 2011 can be absorbed for radiating the first cavity 201; when the air flows through the wireless communication module 42 and the control board 40 in the first cavity 201, the cold energy in the air flow can be exchanged to the wireless communication module 42 and the control board 40 in the first cavity 201, and the heat in the first cavity 201 is taken away, so that the heat dissipation of the wireless communication module 42 and the control board 40 is realized. That is, heat in the first chamber 201 is sent to the first heat sink 2011, so that heat dissipation to the wireless communication module 42 and the control board 40 is achieved.

When at least one of wireless communication module 42 and control board 40 is disposed within second cavity 202 and laminated to a side wall of second cavity 202, the heat dissipation pattern of wireless communication module 42 and control board 40 within second cavity 202 may be different from the heat dissipation pattern within first cavity 201. For example, a second heat sink 2021 may be provided corresponding to the second cavity 202, and the second heat sink 2021 may be provided to dissipate heat inside the second cavity 202 by heat conduction. Thereby effecting heat dissipation from wireless communication module 42 and control board 40. By heat conduction, the heat dissipation efficiency and effect can be improved, and rapid heat dissipation to the wireless communication module 42 and the control board 40 having a high operating temperature can be achieved.
