Abstract
A heat exchanger for a motor vehicle may include a tube block and a flange. The tube block may multiple first medium channels and multiple second medium channels. The first and the second medium channels may extend from an inlet of the tube block to an outlet of the tube block. A medium to be cooled may flow through the first medium channels. A cooling medium may flow through the second medium channels. The flange may be configured to receive the tube block about the outlet in a fluid-tight manner. The flange may be plate-like and may have a surrounding bolting region that may be formed about the tube block.
Claims17
A heat exchanger for a motor vehicle, comprising:
- a tube block including multiple first medium channels and multiple second medium channels,
- the first medium channels extend from an inlet of the tube block to an outlet of the tube block, and a medium to be cooled flows through the first medium channels and a cooling medium flows through the second medium channels;
- and
- a flange configured to receive the tube block about the outlet in a fluid-tight manner,
- the flange is plate-like and has a surrounding bolting region that is formed about the tube block, and the flange extends transversely to a flow direction of the medium to be cooled;
- wherein the flange is formed in two layers in the bolting region including a first material layer and a second material layer;
- in the bolting region, multiple beads for stiffening the bolting region are formed;
- and
- within the beads, openings for applying a fluxing agent between the first and second material layers are formed in the first material layer or in the second material layer.
A heat exchanger for a motor vehicle, comprising:
- a tube block including multiple first medium channels and multiple second medium channels, the first medium channels extend from an inlet of the tube block to an outlet of the tube block, and a medium to be cooled flows through the first medium channels and a cooling medium flows through the second medium channels;
- and
- a flange configured to receive the tube block about the outlet in a fluid-tight manner, the flange is plate-like and has a surrounding bolting region that is formed about the tube block, and the flange extends transversely to a flow direction of the medium to be cooled;
- wherein the flange is formed in two layers in the bolting region, a first material layer is formed from a material of the flange and a second material layer by a folding of the first material layer;
- and
- the first material layer and the second material layer are soldered to one another.
A heat exchanger for a motor vehicle, comprising:
- a tube block having an inlet fluidly connected to an outlet;
- one or more first medium channels extending from the inlet to the outlet;
- one or more second medium channels extending from a second inlet to a second outlet;
- and
- a flange configured to receive at least a portion of the tube block, the flange including a bolting region and disposed proximate the outlet
- wherein the flange is formed in two layers in the bolting region, a first material layer is formed from a material of the flange and a second material layer by a folding of the first material layer;
- and
- the first material layer and the second material layer are soldered to one another.
