The influence of pulsation phenomenon of Pulsating Heat Pipe

In the work of Pulsating Heat Pipe, the pulsation oscillation phenomenon of liquid is inevitable. This is because the thermal expansion and cooling contraction of the liquid in the Pulsating Heat Pipe are intermittent, and the cycle of these expansion and contraction will also change due to the influence of external environmental conditions.

Pulsating Heat Pipe

The pulsation phenomenon of Pulsating Heat Pipe is mainly manifested as the fluctuation of physical quantities such as pressure, temperature, and flow. The amplitude and period of these fluctuations are different, some are periodic, and some are random. These pulsation phenomena have a great influence on the heat transfer performance and working efficiency of Pulsating Heat Pipe.

The pulsation phenomenon in Pulsating Heat Pipe will cause eddies and oscillations inside the liquid, which will bring some adverse effects, thereby reducing the heat transfer performance of the heat pipe. On the one hand, the pulsation phenomenon may cause local overheating or overcooling areas in the liquid, which will affect the uniformity and efficiency of heat transfer and reduce the performance of the entire system; on the other hand, the instability of liquid flow will also cause the turbulence of the liquid in the heat pipe to increase, thereby increasing the pressure drop and operating resistance of the system, further affecting the heat transfer performance.

Working principle of Pulsating Heat Pipe

Loop Thermosyphon Application Industry

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.
