Usage of Thermoelectric Cooler

Example of milk cooler: Recently, all-you-can-drink booths in various restaurants are increasing, so beverage dispensers or coffee machine are installed. This kind of coffee machine takes advantage of a thermoelectric-module-based milk cooler. It can store and refrigerate 2 to 4 packs of 1 liter milk packs and its compact, clean, safe concept are greatly valued.

Control board cooler: Thermoelectric coolers are applied in the cooling control board or communication cabinet for networks in factories. In the board, focus on cooling a spot where the parts are especially heat-sensitive or a whole cabinet, they are used in many kinds of applications. Moreover, this kind of system is very vulnerable to water, so it can also supply cool air to control the temperature to decrease condensation and combined with a drain as a solution.

Temperature control for LD: LD is the main component of optic electronic devices. Among them, LD with long emission wavelength from 1.3~1.55µm, higher capability ones will need to be cooled or controlled at constant temperature. Thermoelectric coolers are applied widely to cool this sort of limited space device.

Compact refrigerator: Because of the advantages of no vibration and noise, plus its small cooling structure, thermoelectric coolers have been applied in industrial refrigerators for hospital or hotel’s guest room since 10 years ago. These days, due to the fact that production has cost decreased and reliability has advanced, it started to be used in some consumer products gradually.

Spectral photometer: Spectral photometer: Protein material or enzyme reactions etc. are affected easily by temperature, and absorbance will change significantly as well. Using thermoelectric coolers to precisely control the temperature of samples, and because temperature-responsive is good, correct and rapid measurement and evaluation become possible.

Temperature control for silicone wafers: In the beginning process of semi-conductor chip production, a sequence of processing silicone wafer is requiring to have +/-0.1C precise temperature control. By switching cool/heat or controlling voltage/current, it is quite easy and precise to fulfill the temperature control using a thermoelectric cooler, plus the merit that the system can be compact, so it is used widely.

Compact thermostatic chamber: It is required to control the temperature around room temperature to bodily temperature when culturing organisms. Thermoelectric cooler is the most appropriate to precisely control the temperature around room temperature, which is difficult for cooling machines and heater, etc. Moreover, in this kind of experiment, most situations need to have cool/heat cycled environment, so that due to this polarity switch, the cool/heat reversible thermoelectric cooler is quite popular.
