Abstract

A modulator assembly for a condenser. The modulator assembly has a tube having a first end and a second end. A first connector is brazed to the first end of the tube. A second connector is threadably secured at the second end of the tube.

First claim

What is claimed is:

1. A modulator assembly for a condenser, the modulator assembly comprising:
a tube having a first end and a second end, the tube defines an inlet opening proximate to the first end and an outlet opening proximate to the second end, with the tube connected to a tank of the condenser the inlet opening aligns with a tank inlet and the outlet opening aligns with a tank outlet;
a first connector brazed to the first end of the tube, the first connector is configured to direct refrigerant through the inlet opening and the tank inlet into the tank of the condenser; and
a second connector threadably secured at the second end of the tube, the second connector is configured to direct refrigerant out from within the tank and out of the modulator.

2. The modulator assembly of claim 1 , wherein the second connector is threadably coupled to threads at the second end of the tube.

3. The modulator assembly of claim 1 , further comprising a connector assembly at the second end of the tube, the connector assembly including a block brazed to the second end and the second connector threaded into cooperation with the block.

4. The modulator assembly of claim 3 , wherein the tube is extruded aluminum, the first connector includes aluminum, the second connector includes aluminum, and the block includes aluminum.

5. The modulator assembly of claim 3 , wherein the block includes internal threads and the second connector includes external threads configured to mate with the internal threads of the block.

6. The modulator assembly of claim 1 , wherein the first connector is an inlet connector, and the second connector is an outlet connector.

7. The modulator assembly of claim 1 , wherein the first connector is an outlet connector, and the second connector is an inlet connector.

8. The modulator assembly of claim 1 , wherein the tube includes a first tank mating portion proximate to the first end, the first tank mating portion including: a planar surface at an exterior of the tube surrounding the inlet opening; and legs on opposite sides of the planar surface, the legs are curved to match an outer radii of the tank such that the legs mate with the tank.

9. The modulator assembly of claim 1 , wherein the tube includes a second tank mating portion proximate to the second end, the second tank mating portion including: a planar surface at an exterior of the tube surrounding the outlet opening; and legs on opposite sides of the planar surface, the legs are curved to match an outer radii of the tank such that the legs mate with the tank.

10. The modulator assembly of claim 1 , wherein the tube is brazed to the tank at the inlet opening and at the outlet opening.

11. The modulator assembly of claim 1 , further comprising at least one mounting bracket brazed to the tube, and at least one mounting bracket brazed to a header tank at an end of the condenser opposite to the modulator.

12. A condenser assembly comprising:
a condenser including a core, a first tank at a first end of the core, and a second tank at a second end of the core;
a modulator assembly including a tube connected to the first tank such that an outlet opening defined by the tube is aligned with a tank inlet of the first tank, and an inlet opening defined by the tube is aligned with a tank outlet of the first tank;
an inlet connector brazed to a first end of the tube; and
an outlet connector assembly at a second end of the tube, the outlet connector assembly including a block brazed to the second end and a second connector threaded into cooperation with the block.

13. The condenser assembly of claim 12 , wherein the tube is brazed to the first tank at a first interface between the outlet opening and the tank inlet, and at a second interface between the inlet opening and the tank outlet.

14. The condenser assembly of claim 12 , wherein the tube is extruded aluminum, the inlet connector includes aluminum, the outlet connector includes aluminum, and the block includes aluminum.

15. The condenser assembly of claim 12 , wherein the tube includes a first tank mating portion proximate to the first end, the first tank mating portion including: a planar surface at an exterior of the tube surrounding the inlet opening; and legs on opposite sides of the planar surface, the legs are curved to match an outer radii of the tank such that the legs mate with the tank.

16. The condenser assembly of claim 12 , wherein the tube includes a second tank mating portion proximate to the second end, the second tank mating portion including: a planar surface at an exterior of the tube surrounding the outlet opening; and legs on opposite sides of the planar surface, the legs are curved to match an outer radii of the tank.

17. The condenser assembly of claim 12 , wherein the block includes internal threads and the second connector includes external threads configured to mate with the internal threads of the block to removably connect the second connector to the block and allow insertion of a desiccant within the tube.

18. The condenser assembly of claim 12 , further comprising at least one mounting bracket brazed to the tube, and at least one mounting bracket brazed to a header tank at an end of the condenser opposite to the modulator.
