Description

Technical Field

[0001] The invention belongs to the field of cooling devices for electrical cabinets, and in particular relates to an automatic control type cooling structure for electrical cabinets. Background Art

[0002] The switch cabinet is a large-scale electrical equipment with a large number of electronic components inside. These electronic components generate a lot of heat when working, causing the temperature inside the switch cabinet to rise and the gas to expand rapidly, which can easily cause damage to the electronic components. Therefore, timely heat dissipation is required. At present, air flow is generally introduced and exported through the air inlet and exhaust pipes, so that the heat inside the electrical cabinet is continuously discharged. In order to prevent dust from entering the electrical cabinet, a filter is generally set on the air inlet pipe to filter external dust. However, after a period of use, a large amount of dust particles will be attached to the filter, which will block the air flow when passing through the filter. This will cause blockage in the air flow, making the air flow inside the electrical cabinet not smooth, and the heat discharge inside the electrical cabinet not smooth, which can easily cause excessive heat to damage the internal electronic components. For this reason, the filter needs to be cleaned manually on a regular basis, which is inconvenient and will cause untimely heat dissipation if forgotten. Summary of the Invention
