Heat exchanger and method of connecting
View Patent ↗The invention provides a heat exchanger, such as a charge air cooler, having a connecting plate, which is arranged in a housing into which the charge air flows. Charge air flows through ducts, which are assigned to the charge air and are provided with fins. The housing includes an assembly opening into which the heat exchanger can be inserted and is to be fastened by its connecting plate, with the body of the heat exchanger likewise being fastened in the interior of the housing. The charge air cooler has end chambers for a coolant. The end chambers are connected to coolant ducts. A strip is formed in the interior of the housing between two end chambers. The strip extends over a substantial part of the length of the end chambers.
1. A heat exchanger comprising:
a heat exchanger body including two end chambers located at a first longitudinal end of the heat exchanger body for receiving a coolant and coolant ducts having fins, the end chambers being connected to the ducts;
a housing defining an interior through which charge air flows and including an opening for receiving the heat exchanger body;
a connecting plate secured to the housing; and
a strip positioned in the interior of the housing between the end chambers and extending over at least a portion of a length of the end chambers, preventing charge air from traveling around the end chambers, and causing substantially all of the charge air to travel across at least one of the ducts and the fins.
2. The heat exchanger of claim 1 , wherein the strip is a first strip, and wherein a second strip is positioned between two other end chambers located at a second longitudinal end of the heat exchanger body.
3. The heat exchanger of claim 2 , wherein the first strip extends from a wall of the housing and the second strip extends from an opposite wall of the housing.
4. The heat exchanger of claim 1 , wherein the strip extends in the insertion direction of the heat exchanger body with respect to the housing.
5. The heat exchanger of claim 1 , wherein the strip extends into a free space between the end chambers and cooperates with the heat exchanger body to form a region closed to charge air flow such that the strip substantially prevents the charge air flow from entering and flowing through the region of the heat exchanger body.
6. The heat exchanger of claim 1 , wherein the strip has a conical cross-sectional shape.
7. The heat exchanger of claim 1 , wherein the heat exchanger is a charge air cooler.
8. The heat exchanger of claim 1 , wherein the strip protrudes from a wall of the housing.
