1、The semiconductor cooler is a solid-state refrigeration technology that combines semiconductor technology and electronic assembly technology. 2、High quality cold plate, large power, stable work and low noise. 3、The area of the guide block is larger and the cooling is good. 4、Water cooling head with fins, internal fin design, larger contact surface with water and more sufficient cooling. 5、Can be used for small space cooling, such as flat product cooling. It is also suitable for small space cooling, refrigeration equipment planning for research solution development. Features: The semiconductor cooler is a solid-state refrigeration technology that combines semiconductor technology and electronic assembly technology. High quality cold plate, large power, stable work and low noise. The area of the guide block is larger and the cooling is good. Water cooling head with fins, internal fin design, larger contact surface with water and more sufficient cooling. Can be used for small space cooling, such as flat product cooling. It is also suitable for small space cooling, refrigeration equipment planning for research solution development. Specification: Power supply voltage: 12V Refrigeration power: 120W Appearance size: 150 * 115 * 75mm / 5.9 * 4.5 * 3in Opening size: 123 * 80mm / 4.8 * 3.1in Suitable for pipe: inner diameter of 8mm or 7mm Package List: 1 x Semiconductor Cooler Note: The water circulation needs a time process. If you use the chiller for the first time, the cooling effect will gradually appear. You can also use the thermostat to control the chiller and set the temperature range according to your local environment temperature.
