本发明涉及一种DC/DC电源系统组装结构，包括DC/DC电源模组、系统板及散热元件。DC/DC电源模组包括印刷电路板以及至少一第一散热片。印刷电路板一面具有至少一发热元器件以及至少一用于电气连接的接线端子；第一散热片覆盖发热元器件而露出接线端子。系统板对应于DC/DC电源模组的位置设有开孔。散热元件通过开孔与DC/DC电源模组接触，对DC/DC电源模组进行散热。本发明的DC/DC电源系统组装结构中，散热元件穿过开孔与DC/DC电源模组接触，散热器与系统板之间的距离可通过改变导热块的高度进行调整，结构紧凑，所需要的安装空间小，安装也简单、灵活。;The disclosure relates to a DC/DC power system assembly including a DC/DC power module, a system board and a heat-dissipation unit. The DC/DC power module includes a PCB and at least a first heat-dissipation plate. One side of the PCB has at least a heat-generation component and at least a lead used for electric connecting. The heat-generation component is covered by the first heat-dissipation plate and the lead is exposed. An opening is disposed on the system board and corresponding to the DC/DC power module. The heat-dissipation unit is contacted with the DC/DC power module through the opening for auxiliary heat-dissipation of the DC/DC power module. In the present invention, the heat-dissipation unit is contacted with the DC/DC power module through the opening, and the distance between a heat sink and the system board can be adjusted through adjusting the height of the thermal conductive member, so that the structure of the DC/DC power system assembly of the present invention is compact, the required space of installation is minimized, and the installation is simplified to be flexible. |
