The thermoelectric temperature difference semiconductor refrigerator strictly implements the SJ2856-88 standard and conforms to the quality system of GB/T19001-2000. The product AQL value is 1.5 through the Institute of Semiconductor Physics, Chinese Academy of Sciences (polar switching test, high temperature storage test, low temperature storage test, temperature impact test, impact test) Testing, fully meet ROSHCE product requirements
1. When you do not know the hot and cold surface of the refrigerator, you can use this method to connect the red wire to the positive pole of the power supply, the black wire to the negative pole, and the power can be tested instantaneously without heat dissipation, that is, touched by hand. The two end faces of the device will feel a side of the heat, a slightly cold side, the hot side is the hot side, and the cold side is the cold side. But the time can't exceed 5 seconds, otherwise the device will burn out due to the high temperature of the hot end.
2. Under normal conditions, the lead is usually expressed as a positive pole in red: it is usually indicated by black as a negative pole, which is the wiring method when the thermoelectric cooler is in operation. When heating is required, just change the polarity of the current. Switching power supply must be used for cooling work, and the ripple factor of the power supply should be less than 10
3. The method of identifying the thermocouple logarithm of the refrigerator and the limit voltage. The thermocouple logarithm refers to the number of P and N nodes. For example, the model of the refrigerator is TEC1-12706, then 127 is the thermocouple logarithm of the refrigerator, 06 is the allowable current value A, the limit voltage of the refrigerator = the number of thermocouple pairs × 0.12, for example: TEC1-12706 Limit voltage V=127×0.12=15.2V
4, all kinds of refrigerators, whether in use or in the test, the cooling and heat exchange should wait for the temperature of the hot and cold surface to return to room temperature (usually more than 15 minutes) or it will cause damage to the refrigerator
5. In order to extend the life of the thermoelectric cooler, the sealing treatment should be carried out around the cooling components. Our method is to use 704 silicone seal, the purpose of the seal is to completely isolate the thermocouple of the refrigerator from the outside air. Protects against moisture and moisture and extends the life of the refrigerator
6. When installing, first wipe the two sides of the cooling component clean and apply a thin layer of thermal grease on the hot and cold side of the refrigerator. The surface of the aluminum radiator or cold storage plate that is in contact with the refrigerator should be flat and cleaned, and evenly coated with thermal grease on the surface; the cold surface of the refrigerator must be stored during the installation process. The cold plate should be in good contact, and the hot surface should be in full contact with the surface of the aluminum heat sink. (If tightening with screws, the force of several screws should be uniform, do not excessive or uneven force. To achieve the best cooling effect, Insulation is applied between the cold storage plate and the aluminum radiator, and the thickness is generally 25-30mm.
