Title:
VENTILATION AND HEAT DISSIPATION APPARATUS, AND ELECTROMECHANICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/200230
Kind Code:
A1
Abstract:
The present application relates to the technical field of device protection. Disclosed are a ventilation and heat dissipation apparatus, and an electromechanical device. The apparatus comprises: a main frame connected to a device to be subjected to ventilation and heat dissipation, and a ventilation and heat dissipation module located at the internal portion of the main frame; the ventilation and heat dissipation module comprises 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 which are arranged in a staggering mode; the bottom of the waterproof unit is provided with a drain hole. According to the present application, the waterproof unit located in the main frame is employed to block rainwater outside from entering the internal portion of the device to be subjected to ventilation and heat dissipation, the external air enters the main frame through the external ventilation unit, and heat generated in the running process of the device to be subjected to ventilation and heat dissipation enters the main frame through the internal ventilation unit for heat exchange. The normal heat dissipation of a device in a running process is ensured, and rainwater is prevented from entering the device under different use environments so as to meet the protection grade requirements of an electromechanical device under different use environments.
