Hyper-G Overload Test: PHP Stability Under Extremes

For thermal management in high-vibration/acceleration scenarios (aerospace, automotive, etc.), anti-overload performance is critical. Our team’s hyper-gravity (Hyper-G) test on a custom Pulsating Heat Pipe (PHP) delivered impressive results.

Test Key Points

PHP mounted on a thermal insulation plate; its bottom connected to a calibrated heat source and high-precision thermocouples
Components integrated into a horizontal rotating platform to simulate Hyper-G; temperature data recorded

Core Results

At 500W input, the PHP surface temperature showed minimal fluctuation, with strong anti-overload capability
0-10G overload had a negligible impact on its thermal performance, suitable for extreme dynamic loads

This test confirms PHP as a top choice for critical thermal challenges. We look forward to discussing PHP optimization with thermal engineers, R&D professionals, and industry partners!

PHP Plate: The Ultimate Fix for IGBT Heat Sink Dilemmas

Next-Gen Data Center Liquid Cooling: Copper Cold Plates + Vapor Chambers

Aluminum vapor chamber

High-efficiency two-phase heat spreaders with lightweight aluminum construction. Designed for GPU, CPU, IGBT & power electronics and energy storage systems. Features: ultra-thin profile, high thermal conductivity, customizable size and shape.

Pulsating Heat Pipe (PHP)

Pulsating Heat Pipe (PHP, or Oscillating Heat Pipe) is advanced thermal management tech for high-power electronics, delivering high-efficiency, reliable heat sinks for aerospace, satellites, military equipment and VPX cooling chassis. Different from conventional heat pipes, PHP adopts a simple closed capillary loop charged with working fluid. Driven by fluid phase change, internal oscillation transfers heat rapidly with low flow resistance, requiring no pumps or moving components. Our optimized PHP heat sinks fit compact, mission-critical systems. Lightweight and miniaturized, they run stably and prolong device service life under extreme conditions such as microgravity and severe military environments. Core merits include outstanding heat conductivity, quick thermal response, robust environmental adaptability, low upkeep and broad operating temperature range.

Liquid Cooling Plate (LCP)

Liquid cold plates capture heat through the contact surface and remove heat via precision-engineered internal flow channels. Equipped with dedicated inlet and outlet ports, the liquid cold plate connects to external coolant pumps and cooling loop systems through tubing. The cooling liquid circulates continuously within the internal channel structure, rapidly and efficiently transferring heat away from heat sources.Our liquid cold plates are widely adopted for thermal management and heat dissipation in BESS energy storage systems, EV battery packs, high-power IGBT modules, industrial CPUs, GPUs and other high-power heat-generating equipment.

3DVC Cooler

The 3DVC cooler is developed based on conventional copper vapor chambers and copper heat pipes. It adopts an intercommunicated layout to form an integrated 3D vacuum cavity, with cooling fins welded between individual heat pipe units.
