Inverter Cooling
for Your Loss Map, Module Layout & Installed Conditions

Define your inverter cooling component around the actual heat losses, module layout and available airflow or coolant. Review the shared baseplate, mounting datums, contact stack and delivered manufacturing scope before approving the sample.

Start with Your Loss Map and Installed Interfaces

Define the heat-source layout, contact plane, installation and sample evidence together.

  • Map losses and selected module instructions
  • Define installed airflow or coolant conditions
  • Review contact, mounting and coolant or airflow
  • Agree component and platform acceptance separately
  • Confirm the sample and acceptance evidence
Illustrative loss map and operating cycle concept, not documentary company or customer photography

Loss map and operating cycle

Share the loss distribution across your power devices and other heat sources, switching conditions, duty cycle and temperature limits. Define the validation owner and the installed operating cases, including sustained load and relevant transients.

Illustrative module layout and mounting concept, not documentary company or customer photography

Module layout and mounting

Your inverter cooling mounting interface should identify exact module part numbers, contact footprints, TIM, electrical isolation responsibility and fasteners. Define inverter cold plate mounting holes, datums, adjacent keep-outs and service access on the controlled drawing.

Illustrative air or coolant boundary concept, not documentary company or customer photography

Air or coolant boundary

For an air-cooled part, specify available airflow and the enclosure. For a liquid-cooled part, state fluid, inlet temperature, flow and allowed inverter cooling plate pressure drop at named measurement points. Mark which fittings, seals and brackets are supplied.

Illustrative quote and sample evidence concept, not documentary company or customer photography

Quote and sample evidence

When selecting an inverter cold plate manufacturer, compare the supplied part boundary and evidence against your drawing. Your custom inverter cold plate quote should identify material, manufacturing route, final surface state, quantities and dimensional, leak and separate performance checks.

Choose Your Inverter Cooling Route from the Loss Map

HEAT MAP & INTERFACES↓COMPONENTS & CONNECTIONS↓SAMPLE & AGREED CHECKS↓APPROVED FINISHED PART

For inverter liquid cooling, share the heat-source locations, dissipated losses, fluid, inlet temperature and flow allowance. An inverter heat sink prototype needs the installed airflow, enclosure clearances and fin direction. Keep inverter cooling thermal resistance tied to named temperature nodes and the specified configuration; output power alone does not define the cooling requirement.

  • Define the supplied parts, material and connection boundary.
  • Review your critical interfaces in their final production state.
  • Agree sample evidence before repeat-order release.

3 Views of Your Inverter Cooling Decision

Compare the loss allocation, installed boundary and approval evidence. The chart is a chosen arithmetic example, not a product rating or measured inverter test.

1 · Allocate the chosen losses

Module position A120 W
Module position B180 W
Module position C300 W

Chosen example: 120 + 180 + 300 = 600 W across three module locations. Their shares are 20%, 30% and 50%. These chosen losses are not an inverter output rating, typical efficiency or LK MFG capability. Replace them with your controlled loss map and relevant operating cases.

2 · Define the installed boundary

MODULE FOOTPRINTS + SHARED CONTACT PLANE↓AIRFLOW OR COOLANT + INLET CONDITIONS↓ENCLOSURE + CONNECTIONS + SERVICE ACCESS

Review obstruction, recirculation or flow routing in the actual installation. A bench setup does not automatically reproduce the converter enclosure or hydraulic circuit.

3 · Approve separate evidence

DIMENSIONS + JOINING + CLEANLINESS↓DEFINED LEAK / PRESSURE BOUNDARY↓THERMAL + HYDRAULIC + ELECTRICAL OWNERS

Agree the configuration, loss map, sensors, mounting, interface materials and operating cases. A dimensional report or leak record does not establish installed module temperatures.

Review Your Surface and Cleanliness Requirements

Separate your thermal contact faces, sealing interfaces and wetted passages. Confirm the specified final condition with the mating assembly.

Answers Before You Specify

What inverter data is needed for a custom cooling plate quote?

Provide the controlled plate and assembly drawings, exact module part numbers and mounting instructions, heat-source loss map, temperature limits, operating cycle, contact stack, installed air or coolant conditions, quantities and required sample evidence. Identify the supplied manufacturing boundary.

When should an inverter cooling plate move from prototype to production?

Release the accepted drawing revision after reviewing sample dimensions, mounting fit, material, joining and the specified records. Complete separately agreed thermal, hydraulic and electrical validation for the installed configuration. A visually acceptable sample alone is not production approval.

Does inverter cooling require the same design for IGBT and SiC modules?

No universal shared design can be assumed. Review each selected package, loss map, switching conditions, mounting instructions and interface stack. A change of semiconductor technology may also change the module layout and installed cooling boundary; revalidate the affected interfaces.

Which acceptance tests are needed for an inverter cold plate sample?

Agree material identity, final contact geometry, mounting and port dimensions, fit, cleanliness and any specified leak or pressure checks. Define hydraulic, thermal and electrical validation separately, with operating inputs, sensor locations and approval responsibilities.

Can the inverter output rating be used as the heat load?

Use the relevant dissipated losses and heat-source distribution. Electrical output is not the same quantity as heat entering the cooling component. Share the operating cases and calculation or measurement basis, including the relevant duty cycle and switching conditions.

Will adding external fins or a fan guarantee lower module temperatures?

No. The complete heat path, contact stack, enclosure and installed flow determine the result. Review the approved equipment configuration and validate the actual module temperatures; an exterior surface temperature or photograph does not establish junction conditions.
