Abstract

An intercooler may include an air outlet tank, at least one condensate collector for collecting at least one of condensate, which is separated in the intercooler, and moisture, and a drying agent arranged in the at least one condensate collector. The at least one condensate collector may be arranged in a region of the intercooler accessible to a charge air flow. The drying agent may be able to at least one of absorb, store and discharge at least one of the condensate and moisture to the charge air flow.

First claim

The invention claimed is:

1. An intercooler comprising:
an air outlet tank;
at least one condensate collector for collecting at least one of condensate, which is separated in the intercooler, and moisture;
a drying agent arranged in the at least one condensate collector; and
at least one of:
at least one coolant duct running through the drying agent, and through which hot coolant flows for regenerating the drying agent; and
a bypass pipe leading to the condensate collector and through which warm charge air is able to be blown into the drying agent;

wherein the at least one condensate collector is arranged in a region of the intercooler accessible to a charge air flow; and
wherein the drying agent is able to at least one of absorb, store and discharge at least one of the condensate and the moisture to the charge air flow.

2. An intercooler according to claim 1 , wherein the at least one condensate collector is attached to at least one of the air outlet tank and an air inlet tank.

3. An intercooler according to claim 2 , wherein
the at least one condensate collector is at least one of welded, brazed, adhesively bonded, screwed, or clipped to at least one of the air outlet tank and
the air inlet tank.

4. An intercooler according to claim 1 , wherein
the at least one condensate collector forms an integral constituent part of one of the air outlet tank or
an air inlet tank.

5. An intercooler according to claim 1 , wherein the at least one condensate collector is arranged in such a way that a charge air flow at least one of sweeps over the at least one condensate collector and flows through the at least one condensate collector at least partially.

6. An intercooler according to claim 2 , further comprising at least one clip element arranged on at least one of the air inlet tank and the air outlet tank, the at least one clip element configured to clip the at least one condensate collector to at least one of the air inlet tank and the air outlet tank.

7. An intercooler according to claim 1 , wherein the drying agent has at least one of a molecular sieve and a granulate with at least one of bentonite and silica gel.

8. An intercooler according to claim 1 , wherein at least one of:
the air outlet tank is configured as a nozzle; and
an air inlet tank is configured as a diffuser.

9. An intercooler according to claim 1 , wherein at least one of the air outlet tank and the at least one condensate collector is configured as one of a metallic cast part or a plastic injection-moulded part.

10. An intercooler according to claim 1 , further comprising:
an electric heating device for regenerating the drying agent.

11. An internal combustion engine comprising an intercooler having:
an air outlet tank;
an air inlet tank;
at least one condensate collector for collecting at least one of condensate, which is separated in the intercooler, and moisture, the at least one condensate collector being attached to at least one of the air outlet tank and an air inlet tank;
a drying agent arranged in the at least one condensate collector; and
at least one clip element arranged on at least one of the air inlet tank and the air outlet tank, the at least one clip element configured to clip the at least one condensate collector to at least one of the air inlet tank and the air outlet tank;
wherein the at least one condensate collector is arranged in a region of the intercooler accessible to a charge air flow; and
wherein the drying agent is able to at least one of absorb, store and discharge at least one of the condensate and the moisture to the charge air flow.

12. A method for regenerating a drying agent in an intercooler, comprising at least one of:
conducting hot coolant through at least one coolant duct running through the drying agent; and
conducting warm charge air through a bypass pipe to at least one condensate collector of the intercooler and blowing the warm charge air into the drying agent.

13. An intercooler according to 3 , further comprising at least one clip element arranged on at least one of the air inlet tank and the air outlet tank, the at least one clip element configured to clip the at least one condensate collector to at least one of the air inlet tank and the air outlet tank.

14. An intercooler according to claim 3 , wherein the drying agent has at least one of a molecular sieve and a granulate with at least one of bentonite and silica gel.

15. An intercooler according to claim to 3 , wherein at least one of:
the air outlet tank is configured as a nozzle; and
the air inlet tank is configured as a diffuser.

16. An intercooler according to claim 3 , wherein at least one of the air outlet tank and the at least one condensate collector is configured as one of a metallic cast part or a plastic injection-moulded part.

17. An intercooler according to claim 3 , further comprising:
an electric heating device for regenerating the drying agent.

18. An intercooler according to 4 , further comprising at least one clip element arranged on at least one of the air inlet tank and the air outlet tank, the at least one clip element configured to clip the at least one condensate collector to at least one of the air inlet tank and the air outlet tank.

19. An intercooler according to claim to 4 , wherein at least one of:
the air outlet tank is configured as a nozzle; and
the air inlet tank is configured as a diffuser.

20. An intercooler according to claim 4 , further comprising:
an electric heating device for regenerating the drying agent.
