Abstract

A tube-pin assembly for a heat exchanger of a vehicle includes a housing having an inlet into which exhaust gas flows; a plurality of tubes arranged inside the housing to provide a passage through which the exhaust gas flows; and cooling pins provided between the tubes to provide a coolant passage through which coolant flows, where a foamed metal made of a porous material is provided inside at least one of the tubes.

First claim

What is claimed is:

1. A tube-pin assembly for a heat exchanger of a vehicle, comprising:
a housing having an inlet into which exhaust gas flows;
a plurality of tubes arranged inside the housing to provide a passage through which the exhaust gas flows; and
cooling pins provided between the tubes to provide a coolant passage through which coolant flows,
wherein a foamed metal made of a porous material is provided inside at least one of the plurality of tubes, and
wherein the plurality of tubes comprises:
a first tube having the foamed metal provided therein; and
a second tube comprising a tube region contacting the coolant and a cooling pin region of a bent structure provided in the tube region.

2. The tube-pin assembly of claim 1 , wherein the tube region and the cooling pin region are integrally formed with each other.

3. The tube-pin assembly of claim 1 , wherein a partition for dividing the inlet into a first inlet and a second inlet is provided therein.

4. The tube-pin assembly of claim 3 , wherein the first inlet and the second inlet are defined to have different opening areas from each other.

5. The tube-pin assembly of claim 3 ,
wherein the first inlet flows the exhaust gas toward the first tube; and
wherein the second inlet flows the exhaust gas toward the second tube.

6. The tube-pin assembly of claim 5 , wherein the first inlet is defined by an opening area greater than the second inlet.

7. The tube-pin assembly of claim 5 ,
wherein the front end of the inlet is provided with a bypass valve for determining a flow passage of the exhaust gas,
wherein a temperature sensor for measuring a temperature of the exhaust gas is provided at the front end of the tube-pin assembly, and
wherein the bypass valve is controlled by a controller according to the temperature of the exhaust gas.

8. The tube-pin assembly of claim 7 , wherein the bypass valve is controlled by the controller so that the exhaust gas flows toward the second inlet when the temperature of the exhaust gas is lower than a predetermined temperature.

9. The tube-pin assembly of claim 7 , wherein the bypass valve is completely opened by the controller when the temperature of the exhaust gas is higher than a predetermined temperature so that the exhaust gas flows in proportion to the opening area of each of the first inlet and the second inlet.

10. The tube-pin assembly of claim 7 , wherein the bypass valve is controlled by the controller so that the exhaust gas flows toward the first inlet when the temperature id the exhaust gas is higher than a predetermined temperature.
