Housing module of a fluid treatment module and fluid treatment module

A housing module of a fluid treatment module of a fluid system, the housing module comprising:

• a fluid housing comprising:
• a housing part having:
• a receiving chamber configured to accommodate at least one fluid treatment component for treating the fluid;
• and
• an installation opening at as first axial end of the housing part and opening into the receiving chamber, the installation opening configured to for installation of the at least one fluid treatment component into the receiving chamber;
• and
• the installation opening and receiving chamber defining an installation axis extending through the installation opening and receiving chamber;
• wherein the fluid housing further comprises:
• a housing closure part arranged on and closing the installation opening of the housing part;
• at least one housing connecting section connecting the housing part with the housing closure part to close the installation opening;
• at least one inlet for a fluid to be treated;
• and
• at least one outlet for treated fluid;
• a support structure externally positioned on the housing part and including:
• a connecting shell extending circumferentially at least partially about an exterior of the housing part, the connecting shell including:
• a first fastening region at a first circumferential end of the connecting shell;
• a second fastening region at an opposite second circumferential end of the connecting shell;
• wherein the fastening regions each comprise a plurality of through holes;
• a back shell extending circumferentially at least partially about an exterior of the housing part, the back shell including:
• a reinforcement region extending circumferentially at least partially about an exterior of the housing part;
• a third fastening region at a first circumferential end of the back shell;
• a fourth fastening region at an opposite second circumferential end of the back shell;
• wherein the third and fourth fastening regions reach comprise a plurality of through holes;
• wherein the third and fourth fastening regions are arranged axially below and radially outwardly from the reinforcing region;
• wherein the support structure forms a sleeve part surrounding the housing part;
• wherein, when the support structure is mounted to the housing part, the through holes of the fastening regions of the connecting shell are aligned with respective through holes of the fastening regions of the back shell to receive a fastening member therethrough;
• wherein the housing part and the housing closure part are connected directly to each other by a direct connection;
• wherein the fastening regions are configured for attachment of the housing module on at least one corresponding holding component of the fluid system;
• wherein the connecting shell and the back shell form a sleeve part surrounding the housing part;
• wherein the fastening regions project radially outward away from the housing part.
