激光焊翅片管的选择和验收应注意的问题

将扇顶型翅片管应用于轻质散热器上,由敏铜合金制成,其弹性作用是为散热器与组件壳体的配合提供合力,这种结构在制造和使用上比较简洁,但是翅片功率较低,因而将扇顶型设备应用于毫瓦级晶体管上。肋翅片管能够按不同的形状进行设计,比如等截面矩形直肋、三角形直肋、梯形直肋和凹形抛物线直肋等结构形式。

The fan top finned tube is applied to the light radiator, which is made of copper sensitive alloy. Its elastic function is to provide a resultant force for the matching of the radiator and the module shell. This structure is simple in manufacturing and use, but the fin power is low. Therefore, the fan top device is applied to the milliwatt level transistor. Finned tubes can be designed according to different shapes, such as uniform rectangular straight ribs, triangular straight ribs, trapezoidal straight ribs and concave parabolic straight ribs.

No matter what type of laser welded finned tube is selected, its surface quality and internal

  

不论选用何种形式的激光焊翅片管,都要严厉查看其表面质量和里边质量。一般来说,对其表面质量的要求包含板条加工杰出,表面质量均匀,不允许有包覆层掉落和未包覆现象;包覆层应与芯体合金紧密结合,两者之间无空地或空隙,不允许出现多次弯曲后的裂纹现象。

quality should be strictly checked. Generally speaking, the requirements for its surface quality include outstanding lath processing, uniform surface quality, and no falling or uncoated coating; The cladding layer shall be closely combined with the core alloy, and there shall be no space or gap between them. Cracks after multiple bending are not allowed.
