Description

Technical Field

[0001] The utility model belongs to the technical field of electrical cabinets, and in particular relates to a ventilation window structure of a multi-fan electrical cabinet. Background Art

[0002] The electrical cabinet has a large heat generation due to the complex electrical components inside it, so the electrical cabinet is equipped with a ventilation window with a fan for heat dissipation, and most electrical cabinets are currently equipped with a fan. However, the fan has a certain service life, and there is a risk of failure in the high-temperature environment of the electrical cabinet, and the time of failure is unpredictable. Therefore, once the fan in the electrical cabinet fails, the ventilation window will not play a role in ventilation and heat dissipation, and the temperature in the electrical cabinet will rise rapidly, causing the electrical cabinet to be in a high-temperature state, resulting in the failure of the electrical cabinet, bringing certain economic losses and safety risks. Utility Model Content

[0003] The utility model aims to overcome the deficiencies of the prior art and provide a ventilation window structure for a multi-fan electrical cabinet.

[0004] The utility model solves the technical problem through the following technical solutions:

[0005] A multi-fan electrical cabinet ventilation window structure, characterized in that it includes a ventilation window structure frame, the space within the ventilation window structure frame forms a closed air duct, a plurality of fans are installed in the ventilation window structure frame, an air inlet is provided on the ventilation window structure frame, the plurality of fans collectively correspond to the air inlet, a plurality of wind pressure sensors are provided in the ventilation window structure frame corresponding to the plurality of fans, the fans are connected to the wind pressure sensors, a plurality of air outlets are provided on the ventilation window structure frame corresponding to the plurality of fans, the plurality of fans are respectively connected to the air outlets, shutters are installed on the air outlets, and the plurality of fans are independently connected to an external controller.

[0006] Moreover, the shutter is a one-way non-return shutter.

[0007] Moreover, hanging rings are symmetrically installed on both sides of the upper side of the ventilation window structure frame.

[0008] The advantages and beneficial effects of the utility model are:

[0009] 1. The multi-fan electrical cabinet ventilation window structure of the utility model, after being installed in the electrical cabinet, the grouped electrical cabinet bodies will no longer cause the entire equipment to shut down due to the failure of any one fan. The simultaneous failure of multiple fans in the same electrical cabinet body is an extremely rare event. In addition, in the event of a failure of a fan, the failed fan can be replaced or maintained uniformly as planned, which greatly improves the continuity, stability and safety of each production line.

[0010] 2. The multi-fan electrical cabinet ventilation window structure of the utility model installs multiple fans in a closed air duct at the same time and uses independent controllers to control them. During normal operation, only one fan is started and a wind pressure sensor monitors the operating status of the fan in real time. When a fan fails and stops or the wind pressure is insufficient, the controller of the faulty fan is cut off to stop the fan; at the same time, other fans are started to ensure continuous heat dissipation of the electrical cabinet, and instant switching between the faulty fan and the normal fan is achieved to ensure normal heat dissipation operation of the electrical cabinet.

[0011] 3. In the multi-fan electrical cabinet ventilation window structure of the utility model, a one-way non-return shutter 1 is separately installed at the air outlet of each fan, so that the air duct of the fan is closed when not in operation, thereby improving the heat dissipation efficiency of the fan.
