Characteristics of semiconductor refrigerant
In some thermal control processes that only involve low or medium heat transfer but require complex temperature control, the thermoelectric cooler can provide great help, and it is the only choice in some specific cases. Although no refrigeration method is universal and thermoelectric refrigerators cannot be used in all fields, thermoelectric refrigerators have many advantages over other refrigeration equipment. These include:
No moving parts: Thermoelectric refrigerators only use electric energy when working, and there are no moving parts. In this way, they basically do not need maintenance.
Small size and weight: The volume and weight of a thermoelectric refrigeration system is far less than the corresponding mechanical refrigeration system. In addition, for various strict application requirements, there are various standard or special sizes and layouts to choose from.
It can be cooled to below ambient temperature: The traditional radiator can only be used when the temperature is above the ambient temperature. Unlike the thermoelectric cooler, it has the ability to reduce the object temperature below the ambient temperature.
The same device can meet the requirements of temperature rising and cooling: The thermoelectric cooler can adjust the cooling or heating mode by adjusting the direction of the loaded DC current. Using this feature, it is not necessary to add another independent heating or cooling functional element in a given system.
Accurate temperature control: Since the thermoelectric cooler has a closed circuit temperature control cycle, it can accurately control the temperature within 0.1 ℃.
High reliability: The thermoelectric cooler has high reliability due to its solid base structure. Although it is related to the application conditions to some extent, the service life of typical thermoelectric coolers can generally reach more than 200000 hours.
Electronic mute: Different from the traditional mechanical refrigeration device, the thermoelectric cooler basically does not produce any electronic interference signal in the working process. It can be connected to the sensitive electronic sensor without interfering with its work. In addition, it will not produce any noise during operation.
