Thermoelectric Cooler Module - Peltier Cooler Module - Peltier Module Water Cooler | Description: Note for use in refrigeration:
1. The red wire is connected to the power wire is connected to the anode, cathode, and without cooling conditions, the instantaneous power of the test, which touch the two end of the refrigerator, you will feel a fever, a little have a fever cold, heat, cold cold. But time can not exceed 5 seconds, otherwise the end temperature is too high, extremely easy to cause the device to burn out.
2. Under normal conditions, the lead with red is usually expressed as the positive pole: usually with black as the negative, this is the work of the thermoelectric cooler wiring method. When the current polarity is changed, the polarity of the current can be changed. Refrigeration work must adopt the switching power supply, power supply ripple coefficient should be less than 10%.
3. The number of the thermocouple and the limit voltage of the thermocouple identification method, the number of pairs of thermocouple P, N node. For example: cooler model for TEC1-12706, 127 for cooler thermocouple logarithm, 06 allowable current value: A, the threshold voltage is logarithmic thermocouple cooler * 0.12, for example: limit voltage V TECI-12706 = 127 x 0.12 = 15.4 (V). The normal operating voltage is 78% of the limit voltage, such as the working voltage of 15.4*0.78=12.01V is TEC1-12706.
4. All kinds of cooler in use or in the test, the cooling and heating temperature of and cold exchange should be returned to the room temperature (usually more than 15 minutes). It is easy to cause damage of refrigerator.
5. In order to prolong the life of the thermoelectric cooler, sealing the deal with refrigeration components around. We have two kinds of methods, one is the use of 704 silicone seal; the other is a mining epoxy resin seal, seal is

Product review & video

Hi, guys welcome to electrical projects channel. Today I’ll show a really cool device… I mean it is so cool that it can make ice. It is a thermoelectric cooler, also known as Peltier device. If you connect this device to a 12V DC power source, one side of this device becomes very hot and another side becomes very cold. Since one side of this device becomes very hot I’ll need to use a heat sink. Without a heat sink, one side of this device becomes too hot to touch in a couple of seconds, so good cooling is important here. In order to make heat transfer even better, I’ll use some thermal paste. So, let’s apply some thermal paste. Now let’s press on it, and we’re almost ready to make ice. For an even better heat sink cooling I’ll put it in the water. Now let’s connect a 12 Volts power supply. Now, let’s connect the second wire and cooling starts. Now it is cooling… Let’s put some water dro
