Detail product description:
A dry cell test, test the cooling quality available section
Operation method is: one hand hold the two sides of the refrigeration piece, another hand refrigeration piece of wire in on the poles of the battery (the red lines on the anode, the black line on the cathode), if you can feel a cold is a slight fever, then cooling is good, can work normally.
2, refrigerating working state is fever, while cooling in refrigeration piece of work must be to hot surface good heat dissipation, it is strictly prohibited under the condition of no heat to refrigeration electricity more than 2 seconds, cause overheating burn out buyer beware.Freezing cold heat exchange of electricity must be hot and cold when the two sides to return to room temperature (generally need more than 5 minutes) before being, otherwise easy to cause the cooling circuit damage and the bursting of the ceramic panel.
Three, refrigeration used in refrigeration, the red line to connect power anode, the black line to connect power, negative power requires the use of switch power supply ripple coefficient is less than 10%.General welding has lead to the surface of the ceramic panel hot surface.If the red line to connect power negative, positive black line, the refrigeration piece of hot and cold face.
Four, cooling hot surface not installed a cooling device, do not put through power supply;Poor can lead to high temperature surface cooling heat over cooling hot limit temperature below 100 degrees, and cause cooling overheating burn out.For cooling area is the use of hot and cold surface temperature difference of refrigeration, heat surface temperature is lower, so the grim temperature is lower and the cooling effect is better.
Five, the refrigeration piece is made up of two ceramic panel and semiconductor materials with low melting point solder, strength is not high, belongs to brittle material, the consumer must please take put down gently, do not knock against, can't fall from the sky, to avoid the damage caused by the ceramic panel burst.
Six, cooling types of naming rules is consists of six parts.For example TEC1-12706
The first part: in TE thermoelectric refrigeration components, is the abbreviation of English Thermo - Electric;
Said the second part: the cooling structure category, commonly used ceramic type cooling piece (thermoelectric element cross-sectional area was greater than 1) expressed in C, small ceramic type thermoelectric refrigeration components also known as the miniature electric refrigeration components (thermoelectric element cross-sectional area was 1) or less use S, still have a kind of metal structured with M;
The third part: freezing slice layer (series), with an Arabic Numbers said the cooling chip layer ranged from 1 to 6 layers, layer number, the more the greater the difference in temperature.
The fourth part: refrigeration galvanic couple of logarithmic (P, N nodes number), expressed with three digits, such as 127 pairs.
The fifth part: refrigeration piece of current value, the maximum allowable temperature difference expressed with two digits, such as 6 indicates that the 6 a current, the current is in the best cooling load voltage limit state the limits of current, when raise the temperature of cooling components to cause a decline in current value.
The sixth part: said cooling the surface state, in not more than two letters in English.Not said, without metallization layer single metallic layer with a T, said double-sided metallized layer with a TT said.
Seven, in practical applications, the 127 series (i.e., galvanic logarithm for 127 pairs) of cooling load voltage of 12 v.TEC1-12706, for example, limit voltage of electric double logarithmic 0.12 or 127 * 0.12 * 15.4 V material, normal working voltage is about 78% of the limit of voltage is 15.4 * 78% = 12 V and the working current of the under normal working voltage is about 78% of the maximum allowable current value is 4.7 A, 6 * 78% material low voltage change, current is lower, the higher the cooling radiator piece of hot surface temperature, the current is low;Freezing slice of the maximum refrigerating power = electric double logarithmic * maximum allowable current value * 0.07 = 127 * 6 * 0.07 53 w material;Cooling in the practical application of temperature difference and utilization rate is about 60% ~ 70% of the theoretical value, the power of cooling heat is cooling pills and refrigerating effect of the refrigeration, the sum so freezing slice heat utilization rate of more than 100%.
