Abstract

A fluid guiding module includes a housing having a sensor chamber having first and second chamber ends. The fluid guiding module includes a first connection region for connecting to a second fluid guiding module. The first connection is located on a first outer side of the housing and has a first redirection channel having first and second redirection channel ends. A chamber inlet channel fluidly couples the first redirection channel end to the first chamber end of the sensor chamber. The first redirection channel is adapted to be fluidly coupled to a chamber outlet channel of the second fluid guiding module.

First claim

The invention claimed is:

1. A fluid guiding module, comprising
a housing having a sensor chamber in the housing which extends along a first axis and has a first chamber end and a second chamber end axially distanced from the first chamber end,
a first connection region for connecting to a second fluid guiding module, the first connection region being located on a first outer side of the housing and extending along a second axis and having a first redirection channel which extends along the second axis and has a first redirection channel end and a second redirection channel end axially distanced from the first redirection channel end along the first redirection channel,
a chamber inlet channel fluidly coupling the first redirection channel end to the first chamber end of the sensor chamber,
wherein the first redirection channel is adapted to be fluidly coupled to a chamber outlet channel of the second fluid guiding module,
a second connection region for connecting to a third fluid guiding module, the second connection region being located on a second outer side of the housing and extending along a third axis parallel to the second axis,
a chamber outlet channel fluidly coupling the second connection region to the first chamber end of the sensor chamber,
wherein the chamber outlet channel is adapted to be connected to a chamber inlet channel of the third fluid guiding module,
wherein the first redirection channel and/or a second redirection channel are each adapted to accommodate a sealing unit so that when the fluid guiding module is connected to the second fluid guiding module and/or the third fluid guiding module, the sealing unit is provided in each case to touch a fluid transiting between the fluid guiding module and the second fluid guiding module and/or between the fluid guiding module and the third fluid guiding module;
wherein the first redirection channel and/or the second redirection channel are formed from a circumferential side wall bounding the redirection channel and a bottom wall, wherein the bottom wall is configured as a planar surface and is adapted for receiving the sealing unit.

2. The fluid guiding module according to claim 1 , wherein the first connection region and the second connection region each project from the housing and are adapted to be surrounded by a connecting element, wherein the connecting element is configured to press together the first and second connection regions.

3. The fluid guiding module according to claim 1 , wherein the second connection region comprises the second redirection channel extending along the third axis and having the first redirection channel end and the second redirection channel end axially distanced from the first redirection channel end.

4. A fluid guiding system comprising,
first and second fluid guiding modules, including:
a housing having a sensor chamber in the housing which extends along a first axis and has a first chamber end and a second chamber end axially distanced from the first chamber end,
a first connection region for connecting to a second fluid guiding module, the first connection region being located on a first outer side of the housing and extending along a second axis and having a first redirection channel which extends along the second axis and has a first redirection channel end and a second redirection channel end axially distanced from the first redirection channel end along the first redirection channel,
a chamber inlet channel fluidly coupling the first redirection channel end to the first chamber end of the sensor chamber,
wherein the first redirection channel is adapted to be fluidly coupled to a chamber outlet channel of the second fluid guiding module,
a second connection region for connecting to a third fluid guiding module, the second connection region being located on a second outer side of the housing and extending along a third axis parallel to the second axis,
a chamber outlet channel fluidly coupling the second connection region to the first chamber end of the sensor chamber,
wherein the chamber outlet channel is adapted to be connected to a chamber inlet channel of the third fluid guiding module,
wherein the first redirection channel and/or the second redirection channel are each adapted to accommodate a sealing unit so that when the fluid guiding module is connected to the second fluid guiding module and/or the third fluid guiding module, the sealing unit is provided in each case to touch a fluid transiting between the fluid guiding module and the second fluid guiding module and/or between the fluid guiding module and the third fluid guiding module;
the sealing unit for sealing the first connection region of the first fluid guiding module to the of the second fluid guiding module,
a connecting element for connecting the first connection region of the first fluid guiding module to the second connection region,
wherein the first fluid guiding module and the second fluid guiding module are adapted to fluidly couple the chamber outlet channel of the second fluid guiding module to the chamber inlet channel of the first fluid guiding module by means of the first redirection channel of the first fluid guiding module,
wherein the connecting element is configured to press together the first and second connection regions;
wherein the first redirection channel and/or a second redirection channel are formed from a circumferential side wall bounding the redirection channel and a bottom wall, wherein the bottom wall is configured as a planar surface and is adapted for receiving the sealing unit.

5. The fluid guiding system according to claim 4 , wherein the sealing unit comprises a sealing element and a positioning element, wherein the sealing element and the positioning element are configured to be complementary and adapted for filling the first redirection channel or the second redirection channel in such a way that the sealing element is positioned by the positioning element in the first redirection channel or in the second redirection channel such that the sealing element is aligned with the chamber inlet channel or the chamber outlet channel.

6. The fluid guiding system according claim 4 , wherein the sealing unit comprises a first section having an opening and a second section, wherein the first section and the second section are arranged such that when the sealing unit is inserted into the first redirection channel or the second redirection channel, the opening is adapted to align with the chamber inlet channel or the chamber outlet channel.

7. The fluid guiding system according to claim 4 , wherein the sealing unit has a sealing lip and a redirection opening, wherein the sealing lip is designed such that the sealing lip extends from the first redirection channel end to the second redirection channel end when the sealing unit is arranged in the first redirection channel or in the second redirection channel.

8. The fluid guiding system according to claim 7 , wherein the sealing unit has a sealing rim extending around the redirection opening.

9. The fluid guiding system according to claim 4 , wherein the connecting element has a shape complementary to the connection regions.
