TEC12706
The semiconductor cooler gives us a new concept of heat dissipation, which further controls the temperature of the CPU. With the advent of summer and the rise of ambient temperature, overclockers want to further improve the cooling conditions of the CPU. In the case of a semiconductor cooler, the temperature of the two ends of the plate will produce a certain temperature difference. People use it. The condensing surface provides a low temperature environment for the CPU.
There are many uses for semiconductor refrigerators, which can be used to make portable refrigerating/insulation boxes, hot and cold water dispensers, and the like. Also used for heat dissipation of electronic devices. At present, the semiconductor material Z used in the refrigerator is mainly bismuth telluride, and the impurity is added to the N-type or P-type semiconductor temperature difference element after special treatment. Take the common TEC1-12605 as an example, its rated voltage is: 12v, rated current is 5A, Z large temperature difference can reach 60 degrees Celsius, the external size is 4 X 4 X 0.4Cm, weighs about 25 grams. Its work is characterized by one side of the cooling and one side of the heat.
After the DC power supply is turned on, the electrons start from the negative electrode (-), pass through the P-type semiconductor, absorb heat here, and go to the N-type semiconductor, and then release the heat. Each time an NP module passes, heat is sent from one side to another. On one side, a temperature difference is created, thereby forming a hot and cold end. Installation and use reference
The installation and use of the cooling plate is very simple. Before installation, Z should prepare a little thermal grease. Then, find a dry battery and connect it to the two leads of the refrigerator. You can feel that one end is obviously cool and the other end is hot. Remember the polarity of the lead and make sure. The cold and hot end of the chiller.
When it is officially installed, apply thermal grease on both ends of the refrigerator evenly. Insert a cooling sheet between the CPU and the heat sink. Please pay attention to the direction of the hot and cold surface, the cold surface is attached to the CPU, and the hot surface is strong ( The higher the power, the better.) The heat sink is in contact. Then the idea is fixed three. Be careful that the clip of the fan should not be too short, otherwise it will be difficult to fix.
After fixing, you can connect the cooling chip and the fan to the power supply (must pay attention to the polarity). If your chassis power is less than 230W, I advise you not to connect to the chassis power supply. Otherwise, the power may be insufficient. The computer is not working properly. It is recommended to use an external voltage of about 12V. At this voltage, the cooling capacity of the cooling sheet and the temperature difference between the hot and cold surfaces are suitable. Precautions 
1. Pay attention to the heat dissipation at the hot end.
The hot surface temperature of semiconductor refrigeration should not exceed 60 ° C, otherwise there is a possibility of damage. If the rated cooling voltage (12V), the general cooling fan can not provide enough cooling capacity for the cooling sheet, it is easy to cause overheating damage to the cooling sheet. At the same time, do not energize the refrigerator for a long time without a radiator. Otherwise, the inside of the refrigerator will be overheated and burned. 2. Condensation problems.
When the temperature of the surface of the semiconductor refrigerating chip ceramics is reduced to a certain extent, dew condensation is likely to occur, and whether "condensation" is related to temperature and humidity (the concept of so-called "dew point" in meteorology). The condensation in the computer case is not allowed. The safer method is to make the cold surface of the semiconductor refrigerator work at about 20 °C; it can be adjusted by adjusting the voltage of the cooling fin or the fan speed of the heat sink. Z's good protection measures are to install an anti-condensation, heat preservation, isolation ring, so that it can be separated from the air to avoid condensation! 3, computer power supply problems.
The power consumption of the cooling chip may be as high as 70W. Such a large load may undoubtedly cause problems in the poor quality of the computer power supply. Therefore, please confirm whether the chassis power supply is sufficient when using the player. If the cooling current cannot be reached, the current will be affected. The cooling effect, so the power supply is also the key to the cooling effect.
4. Pay attention to the heat dissipation of the chassis.
Obviously, while the cooling chip reduces the CPU temperature, the heat at the hot end is also quite large, which may cause the temperature inside the chassis to rise and affect the work of other components. Therefore, pay attention to the heat dissipation of the chassis. Add a cooling fan to the appropriate position in the chassis. References: The relevant information is as follows, please buyers carefully read the relevant information
A semiconductor refrigerator (TE), also called a thermoelectric cooler, is a heat pump. It has the advantage of not having mechanically operated components, and is used in applications where space is limited, reliability is high, and refrigerant is not contaminated. The semiconductor refrigerator has the following advantages and features in technical application: 1. It does not require any refrigerant, has a long service life and is easy to install. 2. The semiconductor refrigerator has two functions of cooling and heating.
