Product Description

Stamping Brazed Aluminum Cold Plate for High-Power EV Battery Pack Cooling System

1. Product Introduction

We are a professional battery pack heat exchanger manufacturer specializing in stamping + vacuum brazing technology for liquid cooling cold plates.

Our company designs, manufactures, and distributes heat exchangers for battery packs carrying cylindrical cells, prismatic cells, or pouches. For this product line, we focus on stamped and vacuum brazed aluminum cold plates, which combine the cost-efficiency of stamping with the superior joint strength and leak-tightness of vacuum brazing.

We have full solutions for cooling battery cells, including snake tubes for cylindrical cells (18650, 21700), water cooling plates for prismatic cells, and plate channels for pouches. Our stamping-brazed cold plates are particularly suited for high-volume production of prismatic and pouch cell battery modules.

We hope to utilize our expertise to establish long-term cooperation with you, as battery thermal management is critical in EV operations. Here are a few things we are good at:

Tooling development — We do it in-house, ensuring prompt and accurate initial testing for stamped parts.
Customized shapes — We can produce cold plates in various stamped geometries to fit different battery pack layouts.
Design assistance — Our experienced engineering team provides professional advice on feasibility and optimization of new designs.
One-stop service — We supply not only heat exchangers but also related insulation materials and silicone pads, offering integrated thermal management solutions.

No.	Alloy	Si	Fe	Cu	Mn	Mg	Cr	Zn	V	Ti
1	1050	≤0.25	≤0.40	≤0.05	≤0.05	≤0.05	---	≤0.05	≤0.05	≤0.03
2	1100	≤0.95 (Si+Fe)		0.05–0.20	≤0.05	---	---	≤0.10	---	---
3	3102	≤0.40	≤0.70	≤0.10	0.05–0.40	---	---	≤0.30	---	≤0.10

Both 3003 and 3102 alloys offer excellent corrosion resistance, making them widely used for heat exchange applications. For vacuum brazing, 3003 alloy with a brazing clad layer is the preferred choice due to its optimal flow characteristics during the brazing process.

7. FAQ

Q: Are you a trading company or a manufacturer?

A: We are a manufacturer with over 10 years of experience in stamping, brazing, and thermal management solutions.

Q: What is the advantage of vacuum brazing over other joining methods?

A: Vacuum brazing produces clean, strong, and leak-free joints without flux residue. It is ideal for high-reliability applications like EV battery cooling.

Q: What are your payment terms?

A: Normally, we require 30% T/T in advance, with the balance paid before shipment.

Q: How long does it take for samples and mass production?

A: New mold development and free samples (within 5 kg) typically take 15–20 days. After sample approval, mass production is completed within 25–30 days.

Q: Do you offer OEM/ODM services?

A: Absolutely! We provide full OEM and ODM services, including custom stamping dies and brazing specifications.

Q: Can I get a sample for testing?

A: Of course! We would be happy to provide samples for your quality evaluation.

Q: Is it possible to place a small trial order?

A: Yes, we accept sample orders and also offer design support as needed.
