Heat radiation structure and veneer expansion heat radiation method

The invention discloses a heat radiation structure and a veneer expansion heat radiation method. The heat radiation structure comprises a subrack system and a backplane heat radiation device. The backplane heat radiation device is arranged on a backplane or in a gap between backplanes in the subrack system, is connected with a veneer heat radiator on a veneer through a heat conducting connector, and is used for expanding the convection heat radiation area of the veneer heat radiator. The heat radiation of the veneer is improved. 本发明公开了种散热结构和单板扩展散热方法。散热结构包括：子架系统；和背板散热设备，安装在子架系统中的背板上或者背板间的空隙中、并与单板上的单板散热器通过导热连接器相连接，用于扩展单板散热器的对流散热面积，以此实现改善单板的散热性。
