Abstract

A heat exchanger for cooling a flow of media, comprising a plurality of pipes. The pipes are each received in a respective pipe base at the ends, and the pipes are received in a housing between the two pipe bases, the housing being connected to the pipe bases in a fluid-tight manner. A coolant channel is formed by a shaped region oriented outwards along an outer wall which delimits the housing. The coolant channel has an opening oriented in the direction of the inner volume of the housing, and the coolant channel is in fluidic communication with the inner volume of the housing via the opening. The opening is at least partly covered by a panel, and the panel is arranged on the housing outer wall surface oriented inwards, the outer wall having the coolant channel. A gap is formed between an edge, which delimits the opening, and the panel.

First claim

What is claimed is:

1. A heat exchanger for cooling a media flow, the heat exchanger comprising:
a plurality of tubes, at least a portion of the plurality of tubes being received at ends in a respective tube sheet, wherein the tubes between two tube sheets are received in a housing, which is connected to the tube sheets in a fluid-tight manner;
a coolant channel formed by an outwardly directed shaped region along an outer wall delimiting the housing, the coolant channel having an opening that is directed in a direction of an inner volume of the housing and via which the coolant channel is in fluid communication with the inner volume of the housing, wherein the opening is at least partially covered by a panel that is attached to an inwardly directed surface of the outer wall of the housing, which has the coolant channel; and
a gap formed between an edge delimiting the opening and the panel,
wherein an edge of the panel that extends in a direction of the main extension direction of the coolant channel tapers from a first end to a second end, such that a width of the gap between the edge of the panel and the edge of the coolant channel that delimits the opening, increases or decreases in the direction of the main extension direction of the coolant channel.

2. The heat exchanger according to claim 1 , wherein the coolant channel is disposed at a first end region of the housing, the first end region being closed off by one of the tube sheets.

3. The heat exchanger according to claim 1 , wherein the opening has a rectangular cross section, and wherein the gap is formed between the panel and the edge delimiting the opening and facing the first end region of the housing.

4. The heat exchanger according to claim 1 , wherein the panel is formed by a planar plate element.

5. The heat exchanger according to claim 1 , wherein the inwardly directed surface of the outer wall of the housing having the cooling channel has an at least partially circumferential depression at the edge delimiting the opening, wherein the panel is inserted into the at least partially circumferential depression.

6. The heat exchanger according to claim 1 , wherein the coolant channel is in fluid communication with a fluid connection disposed in the extension of the coolant channel, and wherein the fluid connection is formed as a fluid inlet or as a fluid outlet.

7. The heat exchanger according to claim 6 , wherein the fluid connection is in fluid communication with the coolant channel via a funnel-shaped area, and wherein a flowing of the coolant between the inner volume of the heat exchanger and the fluid connection occurs entirely via the coolant channel.

8. The heat exchanger according to claim 1 , wherein the coolant channel is completely covered by the panel in a direction of the main extension direction of the coolant channel.

9. The heat exchanger according to claim 1 , wherein the housing has two coolant channels, wherein one of the coolant channels is in fluid communication with a fluid outlet and the other coolant channel is in fluid communication with a fluid inlet, and wherein one or both coolant channels are at least partially covered by a panel.

10. The heat exchanger according to claim 1 , wherein the panel is attached directly to the inwardly directed surface of the outer wall of the housing.

11. The heat exchanger according to claim 1 , wherein the panel has broad sides and narrow sides and the two tube sheets each have openings that receive the tubes, and wherein the broad sides of the panel are oriented perpendicular to a respective surface of each of the two tube sheets having the openings.
