Buyers notice:

1 refrigeration slice is divided into cold, hot two sides. Refrigeration pieces are generally printed ascoldThe blank surface isheatNoodles

2 refrigeration chip is generally loaded DC12V voltage (DC)!

3 in the test of the refrigeration chip, there is no case of the radiator installed. Electricity can not exceed two seconds, otherwise it will burn. Responsible buyers themselves!

A simple test method of cooling plate

The operation method is: on the one hand pinch on both sides of the refrigerating sheet, on the other hand wire cooling pad on the two poles of the battery on the (According to the anode, the red black on cathode), if can feel a cold side heat, the cooling plate is good, can work normally.

The use of cooling pad

1 cooling plate working state is a cooling side heating, cooling plate in work must give the hot surface of good heat dissipation, no heat is strictly prohibited in the condition of electricity to the cooling plate more than 2 seconds, causing overheating burn buyers conceit. Through the electric refrigerating plate heat exchange when the hot and cold sides must be restored to room temperature (usually more than 5 minutes) can be broken, otherwise easy to cause line damage and the ceramic panel cooling plate.

2 cooling plate is used as cooling, the red to the black power anode, the cathode of a power supply, switching power supply requires the use of ripple coefficient is less than 10%. The ceramic panel which is generally welded with a wire is a hot surface. If the red line of the cathode of a power supply, the black wire to the positive power supply, is the hot and cold face adjustable cooling plate.

Not installed 3 radiator cooling plate heat surface, do not connect the power supply; bad heat surface heat will lead to high temperature than the hot surface of the cooling plate limit temperature of 100 degrees, resulting in overheating burn out cooling plate. Because the cooling plate is cooled by cold and hot surface temperature, so the heat surface temperature is lower, the surface temperature is lower, the cooling effect is better.

The 4 is composed of two cooling plate ceramic panel and semiconductor material with low melting point solder combination, the intensity is not high, belongs to brittle materials, the user must ask gently, do not bump, but not fell from a height, to avoid the damage caused by the rupture of ceramic panel.

Understanding cooling plate

The naming rules of cooling plate type is composed of six parts. For example TEC1-12706

The first part: TE thermoelectric module, is the abbreviation of Thermo-Electric English;

The second part: structure category cooling plate, ceramic type cooling plate commonly used(The temperature difference electric component section area is larger than1mm²) by C, a small ceramic type thermoelectric module (also known as micro electric refrigeration componentsThermoelectric element is less than or equal to the cross-sectional area1mm²S said, there is a metal structure with M said;

The third part: refrigeration sheet layers (Series), represented by a digital Arabia refrigeration piece from 1 layers to 6 layers ranging from more layers, the greater difference in temperature.

The fourth part: logarithmic cooling plate galvanic (number of P and N nodes), represented by the three Arabia figures, as of 127.

The fifth part: cooling plate allowed maximum temperature value of the current, represented by the two Arabia numbers, such as 06 6A current, the current limiting current in the load voltage limit is the best cooling condition, the temperature rises when the refrigeration component will lead to decline in value of current.

The sixth part: the outer surface of the cooling plate, with no more than two bits English letters. Non metallization layer does not mean that one side of the metallization layer with T, the two sides of the metallization layer with TT.

The practical application of the cooling plate

In practical application, the 127 series (i.e. the number of 127 pairs of galvanic) voltage of the cooling plate general loading is 12V. For example: TEC1-12706, *0.12 logarithmic limit voltage for 127*0.12 = 15.4V thermocouple, normal working voltage is about 78% 15.4*78%=12V limit voltage, working current under normal operating voltage is about 78% of the maximum allowable current value is 6*78% = 4.7A, the voltage is low, current with low heat radiator cooling plate surface the higher the temperature, the current is low; the refrigerating sheet maximum cooling power = maximum allowable current value of galvanic log * *0.07=127*6*0.07 = 53W; cooling plate in the practical application of the temperature difference and the utilization rate of about 60% to 70% of the theoretical value, the heat cooling plate is the cooling plate power and cooling pad cooling capacity and so, if the heating cooling plate utilization rate of over 100%.
