Thermal Management for Industrial Power Supplies

Custom heat sinks and liquid cold plates that turn power losses into a controlled thermal path—from your first prototype to repeatable production.

For power supply OEMs, thermal engineers and sourcing teams. Air cooling / Two-phase cooling / Liquid cooling

Bring your power, space and operating conditions into one cooling brief.

Discuss Your Cooling Project

When Heat Becomes a Limit on Power

A power supply can meet its electrical targets and still lose its thermal margin once it is installed in the cabinet.

Hot cabinet air

A higher inlet temperature leaves less headroom for semiconductor losses.

The result: earlier derating at the operating point that matters.

Concentrated losses

MOSFETs, rectifiers and magnetics place heat in different areas of a compact assembly.

The result: local hot spots that an average temperature can hide.

Restricted airflow

Filters, guards and dense fins move the fan away from its free-air rating.

The result: more noise or less cooling than the bench setup predicted.

Assembly variation

Surface flatness, TIM thickness and clamping force change the thermal interface.

The result: good prototypes that become inconsistent production units.

Identify the constraint before adding more metal or a larger fan.

Review Your Thermal Constraints

Match the Cooling Path to Your Power Supply

Start with the installation environment, heat-source layout and service conditions—not an isolated wattage rating.

Enclosed AC/DC supplies

Limited cabinet space and warm inlet air make fin orientation and enclosure coupling critical.

Find Your Cooling Route

A Cooling Route for Every Thermal Constraint

Compare manufacturing routes against the same heat load, installation space and operating conditions.

One-piece aluminum heat sink with continuous parallel extruded fins and external base mounting holes
For repeatable profiles and distributed component cooling.

Extruded & Board-Level Heat Sinks

6063 aluminum profiles, machined interfaces and mounting features support practical cost control.

Solid copper skived heat sink with dense straight integral fins and open airflow channels
For concentrated heat in a compact forced-air path.

Skived Fin Heat Sinks

Integral copper or aluminum fins reduce an additional fin-to-base joint; spacing is matched to available fan pressure.

Four straight sealed copper heat pipes connecting a copper contact block to aligned aluminum plate fins
For offset hot spots or a larger spreading area.

Heat Pipe & Vapor Chamber Assemblies

Move heat toward the usable fin area while validating orientation, contact load and component clearance.

Closed flat machined aluminum liquid cold plate with two side ports and external corner mounting holes
For high losses with a constrained air-side budget.

Liquid Cold Plates

Tube-in-plate, microchannel, vacuum-brazed and friction-stir-welded routes are selected around the flow circuit and mounting plane.

Compare two viable routes before committing the mechanical envelope.

Compare Cooling Options

Design Around the Installed Operating Point

Define the loss budget and the available temperature rise, then size the thermal path against the conditions inside your equipment.

01 · Define the losses

Share output power, efficiency across the load range, and the location and footprint of each heat source.

02 · Define the boundary

Set the allowable base temperature, worst-case inlet temperature, installed airflow or coolant flow, and the available pressure budget.

03 · Close the interfaces

Confirm contact flatness, TIM thickness, electrical isolation, fixing force and access for assembly.

A practical thermal budget

Output power
2.0 kW
Efficiency
95%
Maximum base temperature
75 °C
Inlet air
45 °C
Internal Heat Dissipation: Loss = 2,000 × (1 / 0.95 − 1) = 105.3 W
Allowable Thermal Resistance: Rθ = (75 − 45) / 105.3
Required Thermal Resistance Target
≤ 0.285 K/W

This steady-state example assumes all 105.3 W enters one heat sink. Allocate losses to the actual cooling paths, validate installed airflow, and check junction and interface temperature rises separately.

Liquid Cooling Without Interface Surprises

A cold plate has to fit the complete circuit: the heat source, coolant, pump, connections and the way it is assembled.

A defined industrial cold plate test specification

  • 0.3 MPa rated working pressure
  • 0.6 MPa hydraulic proof · 10 minutes
  • Final gas leak check after draining and drying

Coolant & materials

Confirm wetted materials, inhibitor package and temperature range together to manage corrosion and long-term compatibility.

Flow & pressure drop

Evaluate base temperature and pressure drop at the same operating point, with the selected coolant—not a water curve alone.

Cleanliness & sealing

Specify internal cleanliness, filtration, port standards, hydraulic proof and final gas leak checks for the approved design.

Mounting & insulation

Control the contact plane, screw loads and TIM; evaluate electrical isolation as part of the power module assembly.

Align the plate and the cooling circuit before the first prototype.
