Working principle of Pulsating Heat Pipe

Pulsating Heat Pipe is a new type of high-efficiency heat transfer device.

Its working principle is mainly based on the flow and heat transfer characteristics of gas and liquid. Pulsating Heat Pipe is usually composed of one or more curved capillaries, which are filled with working fluid.

When working, one end of the heat pipe is heated, and the liquid evaporates at this end to form steam bubbles. Due to the rapid expansion of the volume of the steam, a pressure difference is generated, which drives the steam and liquid mixture to flow to the other end. During the flow process, the steam gradually cools and condenses into liquid, releasing heat, and the liquid is heated at the other end and evaporates again, and so on.

Pulsating Heat Pipe

This pulsating flow allows heat to be quickly transferred from the hot end to the cold end. At the same time, the irregular movement and interaction of the gas-liquid mixture in the heat pipe enhances the heat transfer efficiency.

Pulsating Heat Pipe has many advantages, such as simple structure, low cost, excellent heat transfer performance, etc. It can achieve efficient heat transfer in a small space and adapt to various complex working environments.

In practical applications, Pulsating Heat Pipe is widely used in electronic equipment heat dissipation, aerospace, energy and other fields. It can effectively solve some high heat flux density heat transfer problems that are difficult to solve with traditional heat transfer methods.

The influence of pulsation phenomenon of Pulsating Heat Pipe

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.
