Peltier elements vs. heat sink in cooling of high power LEDs

Enablers for Overcurrent Capability of Silicon-Carbide-Based Power Converters: An Overview

“…An example of such a material is bismuth telluride. Compared to several other ways of cooling, TEC involves no moving parts, which is advantageous from a reliability perspective, and so, TEC has been employed for waste-heat removal [136], LED cooling [137], and solar energy storage [138].…”

Peltier Cell Integration in Packaging Design for Minimizing Energy Consumption and Temperature Variation during Refrigerated Transport

“…In certain designs, it is possible to find "stacked" cells that converge their heat-dissipating sides with the absorbing side of another cell, thus increasing the cooling power in the first cell. Due to all the characteristics of Peltier cells, there are several applications for which they are useful: Badalan and Svasta [35] present the comparison between the operation of an LED with a Peltier cell and an LED using a normal heat sink; Halima et al [36] studied the effect of adding a Peltier cell to the heat It should be noted that Peltier cells are solid devices with no moving parts, and are completely silent, extremely reliable, small, lightweight, and maintenance-free, has a wide temperature range, and are environmentally friendly. However, if Peltier cells consume too much power and a failure occurs, this can destroy the cold side, because when negative temperatures are reached, condensation can occur, depending on the environment and the humidity of the air.…”

“…Designs 2023, 7, 88 3 of 35 Food preservation and transportation are closely related since long-distance food transportation calls for effective preservation techniques. As a result, improvements in transportation technology have been crucial in bringing food to places that are becoming more urbanized and crowded.…”

A Review on Generation of Electricity using Peltier Module

“…Different cooling methods that do not need an external power supply to extract heat from the heat sink were reviewed and experimented [15][16][17][18][19][20].We have this simple demonstration set-up. Since the industrial waste heat is in huge amount, we have used candles to demonstrate this heat as the source Heat is applied to one side of this thermoelectric device and causes electrons to flow through the completed circuit which results in enough power to energise the LED.…”
