Three product families covering every high-heat-flux stage — from a single IGBT module to a complete liquid-cooling loop. Tell us the thermal load, the envelope and the flow rate; we will propose the structure and the manufacturing route.
Embedded tube, friction stir welded (FSW), vacuum brazed and die-cast liquid cold plates for IGBT modules, EV battery packs, ADAS domains, AI server CPU / GPU, and laser or IC test equipment.
Skived fin, extruded, cold forged, stacked fin, HP bonded and composite heat sinks for power supplies, inverters and telecom equipment. Skiving lines run fin pitch down to 0.08 mm with fin length up to 600 mm.
Heat pipe assemblies, vapor chambers (VC) and HP bonded heat sinks on 75 heat-pipe production lines — in mass production for game consoles, laptops, telecom and compact high-power devices.

Founded in Dongguan in 2009, Winshare Thermal has grown from a 3C thermal-kit workshop into a 800-employee liquid-cooling manufacturer serving automotive, green-energy, semiconductor and AI infrastructure customers worldwide. Meeting our customers' needs is our highest development principle — supported by 200+ engineers in our dedicated new-technology research centre.
From the first drawing to the last shipment, the capability stays in-house — which is why we can hold tolerance, lead time and cost at the same time.
Liquid cooling in production since 2020, with 15 years of accumulated water-cooling technology behind the process window.
A dedicated new-technology research centre: 8+ thermal design, 10+ mechanical design, 20+ process and 38+ project engineers.
Send a drawing or a concept and our engineers return a cooling-structure proposal with manufacturing feedback — typically within 24–48 hours.
A standalone sample team and dedicated prototype line keep first articles moving — samples in 7–15 days after drawing confirmation.
Helium leak detector, thermal-resistance tester, flow-resistance bench, ultrasonic scanner, X-ray, CMM and salt-spray chambers — all on site.
IATF 16949 and ISO 9001 systems, RoHS compliance, 100% leak testing on liquid-cooling kits and full traceability per batch.
AI servers, EVs, energy storage, semiconductor equipment and many more — the fields listed here are only part of what we cool. Wherever high heat flux appears, our engineering team can build the cooling solution for it.
Our largest business — CPU / GPU cold plates, manifolds and complete liquid-cooling kits for AI servers and HPC, engineered for 800 W per die and mass-produced in 100K-class cleanrooms.
Battery cold plates and ADAS cooling modules — 250,000 vehicles on the road.
Cooling pallets and cold plates for battery racks and PCS cabinets.
Power heat sinks and inverter cooling — over 65% share in Sungrow solar stations.
Cold plates for IC test handlers and chip packaging equipment.
IGBT and power-module cold plates, plus consumer-electronics heat sinks.
Precision air and liquid cooling for imaging, laser and diagnostic devices.
Cold-plate performance is decided long before assembly. This is the process chain that runs inside our own workshops.
300 CNC machining centres cut the plate, the channel groove and the sealing face to drawing tolerance.
18 skiving machines form fin pitch down to 0.08 mm, with fin length up to 600 mm for high-density air cooling.
8 FSW centres close aluminium bodies without filler metal — no porosity, no filler wire, no flux residue.
Vacuum brazing up to 2400 × 800 × 800 mm, plus 8-zone copper and 10-zone aluminium brazing lines.
Filler-free laser welding for stainless manifolds and bellows, then washing, passivation, vacuum baking and 100K-class cleanroom assembly.
Every liquid-cooling kit is leak-tested and performance-checked against the agreed acceptance criteria before packing.
Thirteen checkpoints between machining and shipment — not a final spot check.
Take a walk through our 60,000 m² manufacturing centre in Qingxi, Dongguan — CNC machining, skiving, FSW, brazing, die casting and heat-pipe lines under one roof, backed by a dedicated quality centre for helium leak, flow, thermal, X-ray and ultrasonic testing. A second plant is under construction in Chonburi, Thailand for overseas programmes.
No black box. You always know which step your project is in and who is working on it.
Share 2D/3D files, thermal load, flow rate, pressure budget and the available envelope. A rough sketch is enough to start.
Our engineers propose the cooling structure, material, process route and tooling, and flag manufacturing risks — usually within 24–48 hours.
First articles in 7–15 days, then measured in our own lab: thermal resistance, pressure drop, flow rate and leak tightness.
APQP-controlled mass production with PPAP documentation, 100% leak testing, cleanroom packing and shipping from Dongguan or Thailand.
Selected programmes in which our cold plates and heat sinks are already running in volume production — the numbers come from our own project records.
Cold plate assemblies developed for successive generations of flagship GPU super chips, plus an AI server GPU water-cooling plate programme.
Liquid-cooling modules for advanced driver-assistance systems, validated through 20 system reliability checks and in volume production.
Power heat sinks and cooling pallets for photovoltaic and storage systems, delivered into solar power stations worldwide.
Samples and prototypes start from a single piece — we run a dedicated sample team so first articles do not queue behind production. Mass production typically begins at 100–500 pieces depending on the process (skiving, FSW, vacuum brazing), and we will tell you the economic break-even point before you commit.
Send your 2D/3D drawing or even a concept sketch with the thermal load, flow rate and available envelope. Quotations are normally returned within 24 hours and the design proposal within 24–48 hours. After drawing confirmation, samples are typically delivered in 7–15 days.
Embedded copper tube, friction stir welding (FSW), vacuum brazing, copper and aluminium brazing, laser welding, high-frequency welding, diffusion bonding, die casting, stamping, skiving and micro-fin machining. Choosing between them is a cost-versus-performance decision we will make with you.
Every liquid-cooling kit passes a 100% helium leak test, with air leak and pressure-holding tests where the specification requires them. We also run flow-resistance, pulse-flow and thermal-resistance tests, ultrasonic scanning, X-ray inspection and cleanliness checks, then assemble and pack in a 100K-class cleanroom.
Yes. We are IATF 16949 certified and work to an APQP development flow with PPAP documentation. Battery cold plates are in mass production for major Chinese EV makers; ADAS cooling modules are running in more than 250,000 vehicles; and our cold plate assemblies serve flagship GPU super chips and AI server water-cooling platforms.
Our head factory is in Qingxi, Dongguan, Guangdong, China, with 60,000 m² of manufacturing area, and a second plant is under construction in Chonburi, Thailand to support overseas programmes. We ship to North America, Europe, Japan, Korea and Southeast Asia, and we are happy to work through your forwarder or ours.
Send us your drawing, thermal load and target cost. Within one working day you will have a cooling-structure proposal, a process route and an indicative price — no obligation, no sales script.
