Abstract
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.
Claims15
A heat exchange device for a vehicle comprising:
- a heat exchanger;
- a fan generating an airflow passing through the heat exchanger;
- a motor connected to an axis of the fan;
- and
- a shroud attached to the heat exchanger, the shroud including:
- a vertical wall defining a longitudinal direction that is substantially perpendicular to said air flow direction;
- a first hook extending from the vertical wall towards the heat exchanger, the first hook including a first plate portion defining a first gap between the first plate portion and the vertical wall;
- a second hook extending from the vertical wall towards the heat exchanger, the second hook including a second plate portion defining a second gap between the second plate portion and the vertical wall, the second gap is less than the first gap;
- a first protrusion of the second hook protrudes toward the heat exchanger and is elastically bendable;
- and
- a second protrusion protrudes from the vertical wall toward the heat exchanger and is elastically bendable;
- wherein the first hook and the second hook are longitudinally offset from each other;
- wherein:
- the first hook and the second hook hold the heat exchanger in the first gap by elastically clamping an end plate of the heat exchanger between the first plate portion and the first protrusion when the heat exchanger has a first thickness;
- and
- the second hook and the second protrusion hold the heat exchanger in the second gap by elastically clamping the end plate of the heat exchanger between the second plate portion and the second protrusion when the heat exchanger has a second thickness that is greater than the first thickness.
A shroud for attaching a fan to a heat exchanger for a vehicle, the shroud comprising:
- a vertical wall defining a longitudinal direction that is substantially perpendicular to an air flow direction;
- a first hook extending from the vertical wall towards the heat exchanger, the first hook including a first plate portion defining a first gap between the first plate portion and the vertical wall;
- a second hook extending from the vertical wall towards the heat exchanger, the second hook including a second plate portion defining a second gap, which is less than the first gap, between the second plate portion and the vertical wall;
- a first protrusion of the second hook protrudes toward the heat exchanger from the second hook, the first protrusion is elastically bendable;
- and
- a second protrusion protrudes from the vertical wall toward the heat exchanger and is elastically bendable;
- wherein the first hook and the second hook are longitudinally offset from each other;
- wherein:
- the first hook and the second hook hold the heat exchanger in the first gap by elastically clamping an end plate of the heat exchanger between the first plate portion and the first protrusion when the heat exchanger has a first thickness;
- and
- the second hook and the second protrusion hold the heat exchanger in the second gap by elastically clamping the end plate of the heat exchanger between the second plate portion and the second protrusion when the heat exchanger has a second thickness that is greater than the first thickness.
