Embodiment Construction
[0046] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those skilled in the art. In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.
[0047] In equipment protection applications, some electromechanical equipment has special requirements for use. For example, box type substation. The use environment of the box-type substation is outdoors, and there are certain requirements for the protection level. For example, if the dustproof level is required to be level 5, it means that the intrusion of dust cannot be prevented within this level, but the amount of dust infiltrated will not affect the normal operation of the equipment. The waterproof level is required to be level 4, that is, to prevent th...

The application discloses a ventilation and heat dissipation device and electromechanical equipment, belonging to the technical field of equipment protection. The device includes: a main frame for connecting with the equipment to be ventilated and heat-dissipated, and a ventilation and heat-dissipating assembly located inside the main frame; the ventilation and heat-dissipating assembly includes: a waterproof unit, an external ventilation unit and an internal ventilation unit; the waterproof unit is located between the external ventilation unit and the internal ventilation unit. Between the ventilation units, the external ventilation unit and the internal ventilation unit are misplaced; the bottom of the waterproof unit has drainage holes. In this application, the waterproof unit located in the main frame prevents external rainwater from entering the ventilation equipment to be radiated, the outside air enters the main frame through the external ventilation unit, and the heat generated during the operation of the ventilation and heat dissipation equipment enters the main frame through the internal ventilation unit inside for heat exchange. It ensures the normal heat dissipation of the equipment during operation, and prevents rainwater from entering the equipment under different usage environments, meeting the protection level requirements of electromechanical equipment under different usage environments.
Description
technical field [0001] The present application relates to the technical field of equipment protection, in particular to a ventilation and heat dissipation device and electromechanical equipment. Background technique [0002] During the operation of electromechanical equipment such as machinery, electrical appliances, and automation, the motor and other components inside the electromechanical equipment will generate a lot of heat. After solar radiation, the temperature inside the electromechanical equipment will also rise. Therefore, it is necessary to dissipate heat and ventilate the electromechanical equipment during its operation. [0003] The related technology provides a ventilation and heat dissipation device, including: a main frame, an external air inlet, an internal air inlet and a baffle. The internal air inlet is located at the upper part of the main frame, the baffle is located in the main frame and connected with the inner wall of the main frame, and the externa...
