Feature:1. Can be used for small space refrigeration, semiconductor refrigeration learning theory, research plan and development of refrigeration equipment planning2. Thermoelectric refrigeration cooling system support stable work, low noise, no need for refrigerant3. Cooling effect depends on the size of the cooling space, ambient temperature, heat insulation performance, airtightness, etc.4. This cooler can be used as dualcore cooling, aircooling equipment, cooling equipment5. Cool down small spaces such as tablets, computers, experiment boards, pet beds, etc., learn the principle of semiconductor refrigeration, and the company develops cooling equipment researchSpecification:Item Type: Thermoelectric Refrigeration Cooling SystemMaterial: Plastic + aluminumMaximum Power: 140W (2 x 12705 chips)Maximum Current: 12AStable Current: 10AUses: Cooling down small spaces such as tablets, computers, experiment boards, pet beds, etc., learn the principle of semiconductor refrigeration, and the company develops cooling equipment researchPower Parameters:Power Supply Size: Approx. 200 x 100 x 40mm / 7.9 x 3.9 x 1.6inProduct Size(LxWxH): Approx. 9.5 x 12 x 20cm / 3.7 x 4.7 x 7.9in.Package List:1 x Power Cord1 x User Manual1 x Power1 x CoolerNote:1. Because the liquid refrigerant evaporates rapidly in the environment, when the refrigerant falls on the skin, it will absorb a large amount of heat from the skin and vaporize, causing local frostbite. So prevent refrigerant from splashing into eyes and skin.2. Do not contact with open flames, stay away from heat sources, and avoid strong vibrations.
