【选型】热电冷却器TEC PCX系列应用于16孔通道基因扩增仪，最大功率可达82.4W

时间： 2023-04-13 来源：世强

技术问答

客户在研发一款16孔通道基因扩增仪，需要半导体制冷片（TEC），要求尺寸72*16mm，制冷量76W，电压20V左右，电流7A左右，温差70℃左右，TEC用来给反应孔板进行快速升温与降温，由于需要进行不同温度之间的多次循环，所以也需要高的循环寿命。

本文推荐Laird Thermal Systems专为冷热循环系统设计的TEC PCX系列的PCX7-156-F2-1672-TA-RT-W6，料号3387005513，这款TEC具有快速加热和冷却等特性，尺寸为72*16*3.3mm，在热端温度Th=27℃时，最大温差可达73.6℃，最大功率可达76.5W，最大电压为18.3V，最大电流7.2A；3387005513属于专门设计的长条形的TEC，最合适应用在16孔的基因扩增仪上面，并且具有符合要求的电压、制冷量等参数。

此外，Laird Thermal Systems的3387005513还具有以下特点：

1、在热端温度Th=50℃时，最大温差可达82.6℃，最大功率可达82.4W，最大电压为20.3V，能够快速加热和冷却，升降温速率可以大大提高；

2、专为循环应用而设计，温度循环次数30万+次，完全满足医疗PCR仪对寿命的要求；

3、最高工作温度为120℃，高温PCR仪升温最大温度95℃，满足使用要求。

这款TEC具有快速加热和冷却等特性，尺寸为72*16*3.3mm，属于专门设计的长条形的TEC，最合适应用在16孔的基因扩增仪上面。

【选型】专为冷热循环系统设计的TEC PCX系列用于PCR，在热面温度27℃下Qc达到215W

目前市面上96孔PCR普遍采用6片40*40mm尺寸的TEC，而大部分这种尺寸的TEC制冷功率Qc最高在150W以内，Laird Thermal Systems推出尺寸40*40mm的高性能TEC，远高于市面上的同类产品，用在PCR产品上具有显著优势。
