A heat exchanger having a heat exchange surface comprising a plurality of tubes, a pair of tanks, an end plate, and a shroud disposed to cover the heat exchange surface, wherein, the shroud provides a first hook and a second hook at it's a vertical wall, and the end plate is held in place either between the first hook and the second hook, or between the second hook and the vertical wall. With the above structure, the fan shroud assembly can hold two types of heat exchangers having different thickness.
