EV CHARGING EQUIPMENT

Keep charging power thermally stable

Custom heat sinks and liquid cold plates for EV charger power modules, rectifiers and cabinet electronics—engineered around your real operating conditions.

From component losses to production-ready cooling.

Build the thermal margin your charging platform needs.

Discuss Your Charging Project

More power. Less room for heat

Sustained losses, warm inlet air and restricted airflow can overheat compact charger power modules. Derating or protective shutdowns can then reduce delivered charging power or interrupt a session.

Concentrated power losses

Rectifier and DC/DC switching stages concentrate heat at semiconductor interfaces. A local hot spot can set the limit for the entire power module.

Hotter inlet conditions

Solar exposure, recirculated air and warm equipment rooms shrink the temperature difference available for cooling.

Restricted air paths

Filters, dense fins and tight packaging raise resistance. Free-air fan ratings do not describe the airflow through an installed heat sink.

Repeated charging cycles

Load changes and thermal expansion stress contact interfaces, joints and seals over the equipment lifecycle.

Turn your operating constraints into a clear cooling brief.

Review Your Thermal Challenges

Follow the heat. Find the bottleneck

A lower component temperature starts with the complete path from the device interface to the surrounding air or coolant.

Engineering note

We compare the whole thermal path so that improving one interface does not hide a restriction elsewhere.

01 · Device interface

Match contact flatness, TIM thickness and clamping load to the power module.

02 · Heat spreading

Distribute local losses across the available base, fins or liquid-cooled surface.

03 · Heat rejection

Verify installed airflow or coolant flow together with the associated pressure drop.

04 · System boundary

Set limits for inlet temperature, fouling, service access and continuous duty.

Share the heat-source layout and the limits around it.

Map Your Heat Path

The right cooling route for every power stage

Select the structure around heat-source density, available space, flow conditions and the way your charging equipment is assembled.

Extruded Heat Sinks

For modular rectifiers and cabinet power electronics

CNC-finished mounting faces and defined fin channels support repeatable installation and cost-effective volume supply.

Skived Fin Heat Sinks

For compact, concentrated heat sources

Integral copper or aluminum fins add surface area where the available fan pressure can support the fin density.

Heat Pipe Assemblies

For offset hot spots and restricted mounting zones

Transfer heat to an accessible fin area, with orientation and working temperature verified.

Vacuum Brazed Cold Plates

For distributed power-module footprints

Internal fins and multiple flow paths support compact heat rejection with a defined flow and pressure-drop target.

Friction Stir Welded Cold Plates

For larger liquid-cooled power stages

Machined channels and a welded cover integrate the coolant path with mounting and port requirements.

Hybrid Cooling Assemblies

For liquid-cooled main stages with air-cooled auxiliary devices

Coordinate both paths in one mechanical package and define their separate operating limits.

Compare cooling routes against the same charger requirements.

Find Your Cooling Solution

Designed around where your chargers operate

The installation environment changes the cooling brief—even when the power electronics share the same platform.

Highway DC Fast Charging

Outdoor exposure, warm inlet air and repeated sessions call for controlled airflow, serviceable fin paths and validated temperature margin.

Fleet & Depot Charging

Long charging windows and grouped cabinets make sustained duty, coolant distribution and maintainable interfaces central to the design.

Urban & Workplace Charging

Compact housings place pressure on space and acoustic targets. Match conduction paths, air-cooled surfaces and electronics clearances early.

Make your installation environment part of the cooling decision.

Discuss Your Application

Choose with operating data, not a power label

Use the same heat load, source layout and temperature target to compare the practical trade-offs of air cooling and liquid cooling.

Decision input	Air cooling	Liquid cooling
Available temperature margin	Air cooling Ambient and inlet-air temperature define the available margin.	Liquid cooling Inlet-coolant temperature and the device interface define the available margin.
Flow delivery	Air cooling Check the installed fan operating point and airflow through the fin channels.	Liquid cooling Check the pump operating point, branch balance and cold-plate pressure drop.
Packaging	Air cooling Reserve fin volume, ducting and filter access.	Liquid cooling Reserve ports, hose bend radius, drainage and service clearances.
Reliability controls	Air cooling Manage dust loading, vibration and fin or joint integrity.	Liquid cooling Manage cleanliness, coolant compatibility, leak tightness and pressure cycling.
Best starting inputs	Air cooling Loss map, inlet temperature, fan curve and available envelope.	Liquid cooling Loss map, coolant specification, inlet temperature, flow and pressure limits.

Measurement basis: Base hot-spot thermal resistance = (base hot-spot temperature − inlet medium temperature) / effective heat load. Device junction and TIM temperature rises are evaluated separately.

Send the boundaries that determine your cooling architecture.

Compare Your Cooling Options

Small interface details. Lasting thermal performance

Flatness, mounting load and coolant compatibility connect a promising design to a stable assembled product.

A controlled contact face

Specify flatness, surface finish and post-treatment condition at the thermal interface.

Repeatable mounting

Select TIM compression, fastener torque and spring force around the device load limit.

A compatible wetted path

Review all wetted metals, coolant chemistry, seals and the operating temperature together.

Clean, serviceable flow

Define particle control, port orientation, venting and drainage before the drawing is frozen.

Resolve the interfaces before they become assembly issues.

Review Your Mechanical Interface

Prove the design before you scale it

A useful validation plan connects the agreed operating conditions to measurements, acceptance criteria and traceable production records.

Thermal performance

Record heat-source dimensions, losses, inlet conditions, installed flow, sensor positions and steady-state criteria. Compare the base hot spot to the agreed limit.

Flow & pressure drop

Measure pressure drop at the component boundary and verify flow distribution at the selected fan or pump operating point.

Leak & pressure integrity

For liquid-cooled parts, define proof pressure and leak acceptance by the approved design. Preserve individual test records with the component batch.

Dimensions & assembly

Check contact faces, port locations, threads, mounting alignment and the assembled TIM condition against the frozen drawing.

Deliverables: Thermal curves · Flow/pressure-drop data · FAI report · Material and test traceability

Define acceptance criteria your engineering and quality teams can share.

Plan Your Validation

From your first brief to a controlled production part

One project team connects thermal requirements, manufacturability, samples and the documents needed for repeat orders.

01 · Define

Share losses, heat-source layout, allowable temperature, envelope and annual demand.

Output: an agreed requirement list.

02 · Engineer

Compare structures and review material, interfaces and manufacturing constraints.
