DOUBLE-SIDED COOLING APPARATUS FOR POWER MODULE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17946962 titled 'DOUBLE-SIDED COOLING APPARATUS FOR POWER MODULE

Simplified Explanation

The abstract describes a double-sided cooling apparatus for a power module. It consists of a first cooling module that is in contact with one side of the power module and allows cooling fluid to flow through it, and a second cooling module that is in contact with the opposite side of the power module and includes a tube for the cooling fluid to flow through.

  • The first cooling module includes a manifold cover with cooling channels formed by guide walls and a fin plate with fins.
  • The cooling channels in the first cooling module have a blocker that causes the cooling fluid to flow in a mixed form of lateral flow and vertical flow.

Potential applications of this technology:

  • Cooling power modules in electronic devices such as computers, servers, and electric vehicles.
  • Cooling high-power electronic components in industrial machinery and equipment.

Problems solved by this technology:

  • Efficient cooling of power modules to prevent overheating and improve performance and reliability.
  • Uniform distribution of cooling fluid across the power module surface.

Benefits of this technology:

  • Enhanced cooling efficiency due to the mixed flow of cooling fluid.
  • Compact design allows for effective cooling in limited space.
  • Improved thermal management prolongs the lifespan of power modules.
  • Increased performance and reliability of electronic devices.


Original Abstract Submitted

A double-sided cooling apparatus for a power module, includes a first cooling module provided to be in contact with a first side of the power module to which a switching device is mounted, and allowing cooling fluid to flow therein; and a second cooling module provided to be in contact with a second side of the power module provided opposite to the first side, and including a tube allowing the cooling fluid to flow in the tube, wherein the first cooling module includes a manifold cover including a plurality of cooling channels formed by a plurality of guide walls extending in a first direction, and a fin plate including a plurality of fins extending in a second direction intersecting the first direction, and the cooling channel includes a blocker formed in a predetermined portion of the cooling channel so that the cooling fluid in the first cooling module flows in a mixed form of lateral flow and vertical flow of the cooling fluid.
