Thermal Management & Heat Sinks

Cold plates, heat pipe & vapor chamber modules, CDU units — from heat sinks to complete system thermal solutions.

1. Technical Introduction

Sevinol's thermal management line covers both liquid cooling and air cooling, delivering complete thermal components from cold plates and heat sink modules to CDU coolant distribution units for high power-density applications, from prototype validation to volume manufacturing.

Core products: liquid cold plates (embedded copper tube, vacuum brazing, friction stir welding FSW, electron-beam diffusion bonding), heat pipe and vapor chamber (VC) modules (standard heat pipe, composite heat pipe, VC, 3DVC, roll-bond plate, base phase-change), CDU coolant distribution units (rack / drawer / integrated) and quick couplings and tubing. Widely used in IDC data centers, semiconductor equipment, medical CT, EV and power electronics.
