Product Description

Aluminum Micro-channel Liquid Cooling Snake Tube for 4695 Cylindrical Cells

1. Product Introduction

This product is specifically engineered for the thermal management of large-format 4695 cylindrical cells (46mm diameter, 95mm height). Compared to conventional liquid cooling plates or potting compounds, our micro-channel snake tube offers the following core advantages:

Perfect Fit & Superior Heat Transfer: The unique serpentine structure tightly wraps around the 4695 cell surface, maximizing contact area. The micro-channel design greatly enhances heat exchange efficiency per unit volume, achieving a 30%–50% increase in heat transfer coefficient compared to standard tubing.
Lightweight & Space-Saving: Thin-wall aluminum micro-channel technology ensures high strength while significantly reducing weight. The compact design fits seamlessly into battery module gaps without taking up extra space, helping to improve overall battery pack energy density.
Uniform Temperature Control: Precision flow channel design and CFD simulation ensure even coolant distribution across every cell, keeping the temperature difference within the entire module to ±2°C, effectively extending cycle life.

Backed by our advanced manufacturing capabilities, we offer a full turnkey service from concept design and thermal simulation to precision welding and surface finishing.

2. Applications

This product is ideal for high-performance battery systems in:

Premium Electric Vehicles (EVs) – especially models demanding fast charging and stringent thermal safety.
Large-scale Energy Storage Systems (ESS) – for commercial and grid-level projects requiring long-term stability and reliability.
High-power Power Tools & Drones – for scenarios with extreme discharge rates and critical cooling needs.

3. Recommended Material Chemical Composition

Given the larger size and higher heat generation of 4695 cells, we recommend the following aluminum alloys known for excellent thermal conductivity and corrosion resistance:

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
4	3003	≤0.15	≤0.15	≤0.01	0.90–1.10	≤0.03	≤0.03	≤0.05	≤0.05	≤0.05

Both 3003 and 3102 alloys offer superior corrosion resistance, making them ideal for long-life heat exchange applications.
