【应用】厚度仅0.076mm的导热材料Tgard K52-2应用于车载OBC，热阻低至0.22℃·in²/W@50Psi

技术问答

车载OBC（车载充电机）包含电源部分和控制主板部分，是应用于新能源汽车动力电池充电的电能转换装置。其在使用时会涉及大功率充放电过程，这将导致内部电子元器件发热严重，如果不能有效给高发热量的MOS等部位降温，势必会损伤产品使用性能和寿命。在此，推荐使用LAIRD 导热材料 Tgard K52-2填充于MOS与散热器之间，可有效缓解工作过程中的散热问题。

对于MOS部位的散热，很多厂家会采用高导热陶瓷片+硅脂的方案，但是使用过程中会发现工艺性并不好。一是陶瓷受压比较容易碎裂，二是硅脂涂抹不均匀、影响传热性能。也有厂家选用导热绝缘片作为传热介质，同样的，如果想保证导热绝缘片与MOS及散热器良好接触，也需要在导热绝缘片的双面涂抹硅脂，增加操作流程，也会面临上述同样的问题。而Laird Tgard K52-2应用于车载OBC中解决MOS散热问题，具有如下优势：

1、热阻低至0.22 ℃·in²/W@50Psi，在单位时间内可传递更多的热量。

2、厚度薄，只有0.076mm，降低了热量传递路径，有利于快速导热。

3、特殊的产品结构，中间一层PI基材，双面涂覆相变导热层。PI层可提供优异的电绝缘性能，击穿电压高达7.8KV；当MOS温度超过52℃，相变导热层的物理状态将有原来的固态变为粘流态，可以更好的浸润MOS与散热器的表面，接触更充分，可进一步降低接触热阻。

4、耐温范围-60℃~150℃，可满足正常工作温度要求，长期使用可靠性好。

5、TO-220, TO-247, TO-3P, TO-3PL及TO-264等多种标准封装尺寸可供选择，其他规格亦可接受定制。

6、符合ROHS环保要求，满足安规认证。

7、在使用工艺方面，优于陶瓷/绝缘片+硅脂的方案，操作更简便。

综上所示，Laird Tgard K52-2非常适合应用于车载OBC中MOS部位的导热散热。

MOS Switch Tube Selection and Principle Application

When the input voltage UI changes from high to low and the MOS tube changes from the on-off state to the cut-off state, the power UDD charges the stray capacitance CL via RD, charging time constant 1=RDCL, so the output voltage UO must pass a certain delay to change from the low level to the high level.
