Guangzhou Ascend: Leading Micro-heat Pipe Precision Filling with Intelligent Liquid Injection Technology
3 min read
As smartphones and laptops continue to evolve towards high performance and thin designs, heat cooling techniques has become a core bottleneck constraining device performance and user experience. With the high thermal conductivity efficiency and phase-change heat transfer characteristics, micro-heat pipes have emerged as a key solution in the field of electronic cooling. Guangzhou Ascend Precision Machinery Co., Ltd. has achieved technological breakthroughs in intelligent liquid injection pumps and vacuum filling valves, providing high-precision and high-efficiency filling equipment for micro-heat pipe manufacturing, and helping the industry reach higher standards.
Micro-heat Pipes: A Core Technological Innovation in Electronic Cooling
Micro-heat pipes achieve efficient heat transfer through the phase-change cycle (evaporation-condensation) of the working fluid inside. Their core advantages include:
Ultra-thin Design: thicknesses compressible to below 0.4mm, suitable for thin devices such as smartphones and tablets.
High Heat Flux Density Handling: effectively managing the instantaneous high thermal load from chips like CPU and GPU, preventing performance throttling or component failure due to high temperatures.
Flexibility Trend: flexible to fit curved or irregular structures in the future, meeting emerging demands such as AR/VR devices and foldable-screen phones.
Leading global electronics brands have widely adopted micro-heat pipe technology, and the precision of their manufacturing processes directly determines the thermal performance and product yield.
Core processes in micro-heat pipe manufacturing include working fluid filling and sealing control:
High Precision in Fluid Injection: The micro-level injection of working fluids (such as water or ammonia) must be controlled with a deviation of less than 0.3%, otherwise it may lead to dry-out or performance degradation of the heat pipe.
Stringent Vacuum Environment: During the filling process, it is essential to avoid bubble formation, or the capillary structure will be disrupted and the efficiency of working fluid circulation will be affected.
Production Efficiency and Consistency: Traditional multi-station conversion processes are complex and it is hard to meet the needs of large-scale production.
Guangzhou Ascend Solution: Intelligent Liquid Injection Pump + Vacuum Filling Valve
Targeting the pain spot of micro-heat pipe manufacturing, Guangzhou Ascend has launched the FSH-SK series intelligent liquid injection pump combined with the FSH-VLIV vacuum filling valve, optimizing the entire process from liquid injection to sealing:
1. Repeatable Precision of 0.3%: Ensuring high consistency in the quality of each micro-heat pipe.
2. Multi-Specification Compatibility: Supporting customized filling for irregular micro-heat pipes, covering mainstream applications such as smartphones and laptops.
3. Intelligent Control: applying integrated digital control system, supporting data traceability and dynamic adjustment of process parameters.
4. Technological breakthroughs in vacuum filling valves: Capable of injecting working fluid under high vacuum conditions of -95kPa, completely eliminating bubble interference and enhancing the infiltration efficiency of the heat pipe's capillary structure.
5. Sealing and Durability: Made of SUS316L valve body material, corrosion-resistant, long lifespan, suitable for harsh working conditions with working fluids such as ammonia and acetone.
6. CE/ATEX/UL Explosion-Proof Certification: Meeting compliance requirements in high-end markets such as the EU and North America, helping customers break through barriers to overseas expansion.
With the explosive growth of 5G, AI chips, and electric vehicles, the application scenarios of micro-heat pipes will further expand into data centers, energy storage systems, and other fields. Guangzhou Ascend will continue to focus on precision fluid control technology, using intelligent and highly compatible equipment to help customers seize technological high ground and jointly promote the innovation and upgrade of the electronic cooling industry.
