AI Technical Summary
Traditional heat dissipation structures are increasingly unable to meet the demands of high heat flux densities, leading to excessively high temperatures in power secondary relay protection testing equipment, which affects equipment performance, stability, and service life.
A heat dissipation structure for a power secondary relay protection test device is designed. The structure adopts a dual-channel heat dissipation structure, including first and second heat dissipation channel covers and guide plates. The guide plates are equipped with heat dissipation fins, which, together with a cooling fan, form a dual-channel heat dissipation structure to increase the heat dissipation area and efficiency.
It improves heat dissipation efficiency, reduces the probability of equipment failure due to overheating, and extends the service life of the equipment.
