Conventional refrigeration chip(TEC),Also called thermoelectric refrigeration module or thermoelectric refrigeration chip,Usually by many pairsp¡¢nType a semiconductor electric couple arm is composed of series or parallel connection.When a low voltage DC is connected,Heat will be transferred from one end of the refrigeration device to the other,Cause one side of the device to cool down(cold noodles),Temperature rise on the other side(Hot surface).When the current direction changes,Will transfer heat in the opposite direction.thereforeTECIt can be used in special occasions requiring refrigeration or heating.
Manufactured by segrec200The remaining refrigeration chips of different models,Large chip temperature difference,High refrigeration efficiency,High precision,Low power consumption,Long service life,High cost performance,Fast delivery,Good after sales service.

Installation method of refrigeration slice:
1.The working state of the cooling sheet is that one side is cooling and the other side is heating,Good heat dissipation must be provided to the hot surface when the refrigeration blade is working,It is strictly forbidden to power on the refrigeration blade for more than2second,Cause overheating and burn out the buyer is responsible.The power on of the cooling and heat exchange of the refrigeration sheet must be restored to room temperature on both sides of the cooling and heat exchange(General needs5Minutes or more)Before,Otherwise, it is easy to cause damage to the circuit of the refrigeration sheet and rupture of the ceramic panel.
2.When the refrigeration plate is used for refrigeration,The red line is connected to the positive pole of the power supply,Black wire connected to negative pole of power supply,Power supply requires ripple coefficient less than10%Switching power supply for.Generally, the ceramic panel with wires is the hot surface.If the red wire is connected to the negative pole of the power supply,The black wire is connected to the positive pole of the power supply,Then the cooling and heating surfaces of the refrigeration sheet are adjusted.
3.When the radiator is not installed on the hot surface of the cooling sheet,Do not turn on the power supply;Poor heat dissipation on the hot surface will cause the temperature to exceed the limit temperature of the hot surface of the cooling fin100degree,And cause overheating and burnout of the refrigeration plate.Because the refrigeration sheet uses the temperature difference between the cold and hot surfaces for refrigeration,So the lower the hot surface temperature,Then the cold surface temperature is lower,Better cooling effect.
4.The refrigeration sheet is composed of two ceramic panels and semiconductor materials through low melting point solder,The strength is not high,Fragile material,Please handle with care,Do not bump,And you can`t fall from a high altitude,Avoid damage caused by ceramic panel cracking.
