21700 EV Cylindrical Battery Aluminium Micro Channel Serpentine Cooling Tube
Description
21700 EV Cylindrical Battery Aluminium Micro Channel Serpentine Cooling Tube is actually made of Micro-channel Extruded Aluminium Tubes,we also call it multiport aluminum snake tubes or aluminum micro channel serpentine cooling cold pipes, which are unique tubes developed with highly refined manufacturing quality.
According to customers' different requirements of the tube design, we all can be customized the size tube and can be controlled strictly by our precise toolings. We are having very rich experience in the tooling making and calibration. With our extrusion production line improved,we are now able to produce the tube with more than 100mm width and the flat surface.

Advanteage
We are a professional battery pack heat exchanger manufacturer. Our company designs, makes and distributes heat exchangers for battery packs, which carrying cylindrical cells, prismatic cells or pouches.
We have full solutions about cooling the battery cells, for example snake tubes for cylindrical cells (18650,21700); water cooling plate for prismatic cells, and plate channel for pouches.
We do hope to utilize our expertise to have chance to establish long-term cooperation with you , as battery thermal management is very critical in an operation of EV. Here are a few things we are good at:
1. Tooling development — we do it in house, so we can make initial testing prompt and accurate.
2. Making all kinds of heat exchangers — we can do customized shape, to make the parts fit into different packs.
3. Assistance in parts design — we have experienced engineer team, they can provide professional suggestions regarding feasibility of carrying out new designs.
