How to improve heat dissipation of transient high voltage electronic equipment?

The heat dissipation of transient high voltage electronic equipment is analyzed. The more reliable natural heat dissipation method is adopted. Enhance heat dissipation by strengthening the heat conduction and sensible heat storage. Iron rod and ceramic are used to enhance heat conduction and heat storage.

Does sensible heat storage enhance heat dissipation characteristics of electronic devices?

Few researchers, however, have studied the enhancement effect of sensible heat storage on the heat dissipation characteristics of electronic devices. In this research, the issue of an efficient transient heat dissipation method for the aluminum-shelled high-power resistor is raised.

What is the power of thermal storage?

The power (or specific power) of thermal storage refers to the speed at which heat can be transferred to and from a thermal storage device, essentially related to the thermal-transfer process and dependent on a variety of heat-transport-related factors, including heat flux condition, system design, and material properties.

How does heat storage improve transient heat dissipation?

Internal heat conduction and sensible heat storage continue to be the primary method of enhancing transient heat dissipation. To better evaluate the heat storage performance of the resistor, the concept of heat storage efficiency is put forward.

What happens if a high power resistor is used in latent heat storage?

Since high power resistors work in more severe enviornment than other high-power electronic devices, if the latent heat storage method is used, it is likely to experience a solid–liquid-gas phase transition because of the device's high temperature. It may cause the internal air pressure to be too high.

Why is thermal management important for high-power electronic devices?

Efficient thermal management solutions are crucial to ensure the reliability, performance, and longevity of high-power electronic devices. This review paper explores various thermal management techniques, including passive and active cooling methods, advanced materials, and emerging technologies.
