Abstract

A receiver having a receiver housing that has a fluid-receiving chamber, a fluid inlet, and a fluid outlet. A drier is provided in the fluid-receiving chamber. The receiver is has an inlet channel protrudes into the fluid-receiving chamber, which inlet channel has a channel outlet in the fluid-receiving chamber and conducts fluid into the fluid-receiving chamber from the fluid inlet as a channel inlet, the inlet channel being shaped in such a way that the fluid flowing out of the channel outlet flows out in a lateral direction. A condenser having the receiver is also provided.

First claim

What is claimed is:

1. A receiver comprising:
a receiver housing with a fluid-receiving chamber having a fluid inlet and a fluid outlet;
a drying granulate arranged in the fluid-receiving chamber; and
an inlet channel extending into the fluid-receiving chamber from the fluid inlet, the inlet channel having a channel outlet in the fluid-receiving chamber that feeds fluid from the fluid inlet into the fluid-receiving chamber, the channel outlet of the inlet channel being curved in a direction away from a central axis of the receiver, such that the fluid flowing out of the channel outlet flows in a lateral direction at a distance from the central axis of the receiver and initially flows in the lateral direction away from the central axis of the receiver,
wherein the fluid inlet and the fluid outlet each include an opening provided in a base wall of the receiver housing,
wherein the receiver housing includes a top wall that opposes the base wall and side walls that connect between the top wall and the base wall, and wherein the drying granulate is arranged at an upper end of the receiver, such that a portion of the drying granulate directly contacts an inner surface of the top wall of the receiver housing, and
wherein an outer surface of the top wall forms an exterior surface of the receiver housing.

2. The receiver according to claim 1 , wherein above the channel outlet there is an unobstructed volume which comprises at least 50% of a gross volume of the receiver in this section and which extends over a height of at least 50% of the total internal height of the receiver.

3. The receiver according to claim 1 , wherein a receiver volume has a constant cross-sectional area.

4. The receiver according to claim 1 , wherein a cross section of the receiver has a round shape.

5. The receiver according to claim 1 , wherein the channel outlet is a pipe bend.

6. The receiver according to claim 1 , wherein the channel outlet is an obliquely cut pipe end in which a long protruding pipe wall side is folded towards a short pipe wall side.

7. The receiver according to claim 6 , wherein the obliquely cut pipe end is provided at a distal end of the channel outlet.

8. The receiver according to claim 1 , wherein the channel outlet is a pipe socket with an attached or inserted adapter piece made of plastic.

9. The receiver according to claim 1 , wherein the drying granulate is arranged between the top wall and a fluid-permeable retaining disc.

10. The receiver according to claim 9 , wherein the retaining disc is a perforated plastic or sheet-metal disc.

11. The receiver according to claim 1 , wherein a fluid deflector that deflects a flow of fluid from the fluid-receiving chamber to the fluid outlet is coupled with the inlet channel.

12. The receiver according to claim 11 , wherein the fluid deflector is a solid, non-perforated wall that is oriented perpendicular to the longitudinal direction of the inlet channel.

13. The receiver according to claim 12 , wherein a gap for flow-through of the fluid from the fluid-receiving chamber to the fluid outlet is provided between an outer peripheral edge of the fluid deflector and an inner side wall of the receiver housing, such that the fluid flows from the fluid-receiving chamber into the gap, then from the gap into a filter and then from the filter into the fluid outlet.

14. The receiver according to claim 11 , wherein a filter is arranged between the fluid deflector and the fluid outlet.

15. The receiver according to claim 11 , wherein the fluid deflector is a solid, non-perforated wall.

16. A receiver comprising:
a receiver housing with a fluid-receiving chamber having a fluid inlet and a fluid outlet;
a drying granulate arranged in the fluid-receiving chamber; and
an inlet channel extending into the fluid-receiving chamber from the fluid inlet, the inlet channel having a channel outlet in the fluid-receiving chamber that feeds fluid from the fluid inlet into the fluid-receiving chamber, the channel outlet of the inlet channel being curved in a direction away from a central axis of the receiver, such that the fluid flowing out of the channel outlet flows in a lateral direction at a distance from the central axis of the receiver and initially flows in the lateral direction away from the central axis of the receiver,
wherein the fluid inlet and the fluid outlet each include an opening provided in a base wall of the receiver housing,

wherein the receiver housing includes a top wall that opposes the base wall and side walls that connect between the top wall and the base wall, and wherein the drying granulate is arranged at an upper end of the receiver, such that a portion of the drying granulate directly contacts an inner surface of the top wall of the receiver housing,
wherein a fluid deflector that deflects a flow of fluid from the fluid-receiving chamber to the fluid outlet is coupled with the inlet channel,
wherein a filter is arranged between the fluid deflector and the fluid outlet, and
wherein the filter covers the fluid outlet with a first filter side surface and is covered by the fluid deflector on a second filter side surface that opposes the first filter side surface.

17. A condenser for a refrigerant circuit of a motor vehicle, comprising:
a block having a first fluid channel and a second fluid channel, a refrigerant adapted to flow through the first fluid channel and a coolant adapted to flow through the second fluid channel, the first fluid channel being divided into a condensation zone for condensing the refrigerant and into a sub-cooling zone for sub-cooling the liquid refrigerant; and
a receiver arranged in a fluid stream between the condensation zone and the sub-cooling zone or after the sub-cooling zone,
wherein the receiver comprises:
a receiver housing with a fluid-receiving chamber having a fluid inlet and a fluid outlet;
a drying granulate arranged in the fluid-receiving chamber; and
an inlet channel extending into the fluid-receiving chamber from the fluid inlet, the inlet channel having a channel outlet in the fluid-receiving chamber that feeds fluid from the fluid inlet into the fluid-receiving chamber, the channel outlet of the inlet channel being curved in a direction away from a central axis of the receiver, such that the fluid flowing out of the channel outlet flows in a lateral direction at a distance from the central axis of the receiver and initially flows in the lateral direction away from the central axis of the receiver,
wherein the fluid inlet and the fluid outlet each include an opening provided in a base wall of the receiver housing,
wherein the receiver housing includes a top wall that opposes the base wall and side walls that connect between the top wall and the base wall, and wherein the drying granulate is arranged at an upper end of the receiver, such that a portion of the drying granulate directly contacts an inner surface of the top wall of the receiver housing, and
wherein an outer surface of the top wall forms an exterior surface of the receiver housing.
