Description:
- Semiconductor refrigerators have many uses, such as making portable refrigeration/insulation boxes, hot and cold water dispensers, etc. Also used for heat dissipation in electronic devices. At present, the semiconductor material used in refrigerators is mainly bismuth telluride, which is added with impurities and processed to form N-type or P-type semiconductor temperature difference elements.
- Product size: L x W x H = 58 x 60 x 92mm
Precaution:
- The hot end of the refrigeration plate should be well cooled by applying thermal conductive silicone grease. If the heat dissipation is not good, not only will the temperature not be too low, but it is also easy to burn out the refrigeration plate (if the refrigeration plate is directly powered on without heat dissipation, it will quickly burn out the refrigeration plate).
- The water circulation needs to be done well before connecting the refrigeration unit to work (refers to the video above for details).
- Cannot be used as an air conditioner, please understand the law of conservation of energy.
- For buyers who want cold water, this one is not suitable because such a small heat sink cannot dissipate too much heat.
Common problems with frost on the cold end:
1. The ambient temperature needs to be low, usually below 28 degrees Celsius when frosting occurs.
2. It is related to the power of your power supply. If you choose a 12706 cooling chip, it is recommended to use a 12V 6A or higher power supply (except for some power supplies with virtual labels).
3. The cooling space should not be too large, and the sealing should be good. A small insulation box is recommended.
4. The hot end of the cooling plate should have good heat dissipation, and the thermal conductive silicone grease should be evenly applied (on all four sides). The large fan should blow towards the cooling plate (do not use the air inlet to suction next to the cooling plate).
5. Do not turn on the cold end fan, as it allows for high air flow and the temperature at the cold end cannot be too low. This is why others do not send cold end fans. However, if the cold end fan is turned on in a sealed small space, the entire space will be cold!
