ICCP Cabinet- A marine enclosure

Project Overview:

Design, develop, & prototype of Rugged, Corrosion resistant, IP (Ingress Protection) rated, EMI/EMC shielded ICCP Cabinet enclosure used as a marine enclosure power source module for the military ship.

 

WORKFLOW:

The requirement was to make an IP rated enclosure with military standard materials and packaging at low cost.

We Seamless Integrated with Customer’s Core R&D and electronics Team. They provided us with a reference enclosure module and gave details about the components which are to be kept inside that enclosure.

Study:

A detailed study on problems faced in ships such as oscillation, resonance, water spill, breakage, etc. was done.

CAD:

Based on the requirement and mechanical feasibility the 3D design of the enclosure was made and also the material was chosen for that Electro-Mechanical packaging

Prototype:

Sheet metal fabricated prototype was made and tested for standards.

Manufacturing Support:

We transfer the document of the design with the prototype to the client.

We gave potential support to compliance testing and certification and also helped in Manufacture/Tooling vendor coordination & parts qualification for the enclosure.

Tests:

Tests are performed before handing the design.

  • Vibration test

  • High-temperature test

  • Damp heat test

  • mould growth test

  • Drip proof test

  • Bump test

  • Shock/impact test

  • Inclination test

  • Ship motion test

  • EMI/EMC test

 

CHALLENGES:

  • Selection of right material which is rigour, rigid, Corrosion resistant and can withstand the salt water environment

  • Rearrangement of the components

  • Making the service easy

DESIGN SOLUTIONS:

  • The spring-loaded bumper was used on the base to bear oscillation.

  • The asymmetrical arrangement of the components inside the enclosure to reduce the vibration resonance effect on the machine.

  • The arrangement was done based on the frequency of servicing of each component and we also design a front door which can come out and rotate like a swing for easy servicing.

  • We use non-conductive material for doors.

  • A plastic material is used to mount all the electrical part

  • A fan was fixed in both left & right side of the enclosure

  • 1 more sheet metal layer designed on top for strength, IP rating and aesthetic of the product.
