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. There is also a second cooling module that is in contact with the opposite side of the power module and includes a tube for the flow of cooling fluid.

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

Potential applications of this technology:

• Power electronics modules in electric vehicles
• Data centers and server racks
• Industrial machinery and equipment

Problems solved by this technology:

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

Benefits of this technology:

• Enhanced cooling efficiency due to the mixed flow of cooling fluid
• Compact design with double-sided cooling
• Improved reliability and lifespan of power modules

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.
