Working principle of heat pipe exchanger

Heat pipe exchanger is a high-efficiency heat exchange equipment that uses the principle of heat pipe to achieve heat transfer and exchange. In this article, we will introduce the working principle of heat pipe exchanger in detail.

Heat pipe exchanger is mainly composed of heat pipe, evaporator, condenser and working fluid. Heat pipe is a closed pipe filled with working fluid inside, which has good thermal conductivity. The evaporator and condenser are located at both ends of the heat pipe.

Heat pipe exchanger

When the hot fluid passes through the evaporator, the heat is transferred to the working fluid in the heat pipe. The working fluid evaporates into steam after being heated, and the steam moves to the condenser under the pressure difference in the heat pipe. In the condenser, the steam encounters the cold fluid and is cooled and condensed into liquid, and the released heat is absorbed by the cold fluid. The liquid returns to the evaporator under the action of gravity or capillary force to complete a cycle.

Through this cycle, heat is transferred from the hot fluid to the cold fluid, achieving heat exchange. The advantage of the heat pipe exchanger is its efficient heat transfer performance, which can achieve a large amount of heat transfer under a small temperature difference.

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.
