Heat pipe heat dissipation system for electrical cabinet

Abstract

This utility model relates to the field of thermal management facilities for electrical cabinets, specifically to a heat pipe cooling system for an electrical cabinet. The system includes a cabinet body, which is a hollow, closed shell containing electrical components; a partition inside the cabinet body dividing the interior into independent electrical cavity and heat dissipation cavity; and an evaporator section located within the electrical cavity, including an ambient evaporator and at least one heat source evaporator. The ambient evaporator absorbs ambient heat from the electrical cavity, while the heat source evaporator is attached to and distributed with the electrical components within the electrical cavity. Based on the thermosiphon effect and a modular heat exchange structure, the system separates and arranges the condenser and evaporator. This addresses the heat dissipation needs of electrical cabinets with multiple heat sources and high-density components, solving problems such as low efficiency, poor adaptability, and high maintenance costs associated with traditional heat dissipation solutions. It improves heat dissipation efficiency and effectively controls the temperature inside the electrical cabinet within the appropriate operating range for the electrical components.
