Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation equipment, and in particular relates to an air-cooling heat dissipation device applied to a high-voltage motor. Background Art

[0002] High-voltage motors are typically cooled using an air-to-air shell-and-tube heat exchanger. The heat exchanger is typically mounted on top of the motor. The air in the high-voltage motor area communicates with the shell-side air of the shell-and-tube heat exchanger, forming a closed internal air circulation area. The tube-side air inside the shell-and-tube heat exchanger communicates with the outside atmosphere, forming an external air circulation area. However, the internal circulation channels of most current high-voltage motor air-to-air heat exchangers typically allow air to enter from the bottom and exit from the top of the heat exchanger after heat exchange. This prevents direct cooling of the high-voltage motor area, affecting the heat dissipation during operation. Utility Model Content
