用于功率模块的散热器
摘要：
本发明提出了一种功率模块的散热器，功率模块具有基板，散热器包括散热器主体，在散热器主体上设置有容纳槽；与容纳槽连通的冷却剂入口；与容纳槽连通的冷却剂出口，其中，散热器主体具有接触面，接触面构造为能与功率模块的基板密封式接触以在容纳槽处形成散热腔。该散热器使得冷却介质能与功率模块直接接触，从而提高了散热效率。
摘要（英）：

The invention provides a radiator used for a power module. The power module has a substrate; the radiator comprises a radiator main body, a coolant inlet and a coolant outlet, wherein an accommodating groove is formed in the radiator main body; the coolant inlet is connected with the accommodating groove; the coolant outlet is connected with the accommodating groove, wherein the radiator main body has a contact surface; and the contact surface is configured to be in sealing type contact with the substrate of the power module so as to form a heat dissipation cavity in the accommodating groove. By virtue of the radiator, the cooling medium can be in direct contact with the power module, so that heat dissipation efficiency is improved.
