The domains of Mixed Reality (MR), Augmented Reality (AR), and Virtual Reality (VR) have witnessed rapid advancements in recent years. These technologies have found extensive applications across various sectors, including entertainment, education, healthcare, and industrial settings. As these markets continue to experience significant growth, the escalating demands for processing prowess and advanced graphics rendering capabilities have underscored the critical importance of efficient heat dissipation. This is particularly relevant as devices are pushed to perform optimally while adhering to lightweight design constraints. The amalgamation of these technologies has resulted in substantial heat generation during intensive computational tasks and intricate image processing, thereby accentuating the challenge of effective thermal management.

JONES Graphite Heat Dissipation Solution

In response to the thermal challenges presented by MR/VR/AR devices, where sustained chip heat and lightweight design demands converge, JONES’ 6-70 series synthetic graphite would be an ideal and efficacious solution. Engineered with remarkable thermal conductivity exceeding 1000W/m·K, it emerges as a compelling solution for heat dissipation in MR/AR/VR devices. Within these devices, JONES’ graphite products rapidly channels heat from chips to components like frames, ensuring uniform distribution and significantly boosting overall heat dissipation efficiency. This integration leverages JONES’ expertise, forging an innovative thermal management solution for these dynamic technologies.

JONES 6-70 series synthetic graphite products is derived from Polyimide film through high-temperature graphitization at over 2000 degrees Celsius. Its orderly atomic arrangement forms a lattice structure, enabling a surface thermal conductivity exceeding 1200W/m·K. This effectively eliminates local heat hotspots, swiftly distributing heat across the surface and enhancing heat transfer efficiency by expanding the dissipation area.

Conventional heat dissipators employ metals like aluminum and copper, with thermal conductivities around 100-400W/m·K. JONES’ synthetic graphite heat dissipation solution ingeniously blends synthetic graphite with traditional metal dissipators, introducing a pioneering breakthrough in the realm of thermal management.

The Combination Comprises 3 Primary Methods

1. Bonding the graphite surface to the heat dissipator using PSA(pressure-sensitive adhesive). This method is straightforward, cost-effective, but PSA might restrict heat dissipation efficiency.
2. Employing thermal grease to fill the gap between the graphite and the dissipator. This method offers operational convenience and low thermal resistance but introduces some impact on cleanliness.
3. Copper-plating the graphite surface and welding it onto the heat dissipator. Despite its complexity, this method achieves the lowest thermal resistance.

As the MR, AR, and VR markets continue to evolve, the critical role of heat dissipation materials in ensuring device performance, user experience, and device reliability is increasingly evident. The efficacy of heat dissipation design and material selection stands as an essential factor for the successful application of these cutting-edge technologies. With over two decades of experience in the heat dissipation field, JONES has been dedicated to continuous innovation in thermal management solutions and Functional Polymer Material technology. Currently, JONES’ synthetic graphite films and innovative integration solutions with traditional metal heat dissipators have been successfully implemented in the first-generation MR devices of JONES’ major clients.

Charging piles have experienced rapid growth as a vital component of the new infrastructure strategy, supporting the widespread adoption of new energy vehicles. As part of this digital and intelligent transformation, charging piles are evolving towards high-power charging, energy interconnection, and orderly charging. Like modern-day “gas stations” for electric vehicles, charging piles face the challenge of meeting the demands of fast charging, resulting in increased heat generation from electronic components. JONES offers a dependable solution for heat conduction, sealing, and potting to address these challenges.

Charging piles employ various heat dissipation methods, including natural heat dissipation, forced air cooling, liquid cooling, and air conditioning. AC charging piles, which consist of a main control board housing heat-generating components like the main control and communication modules, primarily rely on natural heat dissipation. JONES tackles this by minimizing thermal resistance between the main control board and the aluminum shell using Thermal Interface Material (TIM). JONES offers different TIM options, such as Thermal Pad, Thermal Gel, Thermal Grease, and Phase Change Material (PCM), all of which exhibit low thermal resistance and excellent insulation properties. Furthermore, JONES also offers conformal coating solutions for PCB protection, featuring functions such as moisture resistance, insulation, and leak prevention, as well as customized CIPG or FIPG housing sealing solutions designed to match customer processes.

JONES provides a comprehensive solution to address the critical issues of heat dissipation and sealing in charging piles. As the demand for high-power charging and energy interconnection continues to grow, JONES remains dedicated to delivering reliable, high-quality products and outstanding customer service, contributing to the advancement of the new energy vehicle infrastructure.

Charging Pile Heat Conduction & Sealing Scheme

The reliability of charging cables, serving as the interface between the power source and the electric vehicle’s battery system, is crucial. These cables endure repeated insertions, removals, and mechanical collisions during gun head connections. To ensure robust performance, some gun heads are filled with thermally conductive potting glue for terminal fixation and wire connections. JONES offers cost-effective, high-performance potting adhesives that fully encapsulate cables and wires within charging connectors, ensuring long-lasting durability and reliability for high-voltage components.

Charging Gun Potting

JONES takes pride in its independently researched and developed thermal interface materials, EMI materials, and adhesives. From initial development and design to supply chain management, production, and delivery, JONES maintains a customer-centric approach throughout the entire process. This commitment ensures product quality and exceptional after-sales technical support, granting customers peace of mind.

During 14th Oct., 2015 to 17th Oct., 2015, Korea Electronics Show 2015(KES) was held in Goyang, Korea. JONES attended KES and had a booth there for display during the show. The show was successful and JONES team did a great job at the show for presenting our products and making new friends.

This year was the 46th KES show since established in 1969. The location for KES this year was at KINTEX, just 30 minutes drive from city centre of Seoul.

Our booth was located at the opposite of Samsung electronics, and right next to GoPro.

Therefore, basically we were crowded all the time during the first two days of KES. If you are not careful enough about where you stand, you could have easily swallowed by the slowing moving crowd. There were less people during the last two days of KES, which is great for us to walk around the exhibition.

There were also many participants were highly interested by our booth. We had great times together learning from each other at our booth.

It is always nice to sit down and talk despite the noisy crowd when attending to a show or an expo, we can introduce our products and solutions to others, and meanwhile we have opportunity to learn from others.

Fortunately, we have met some old friends and it is glad to know they are doing great nowadays. Moreover, we have made some new friends in the business, too, and we are looking forward to work with them in future.

Good times are always seems to be short, this applied to Korea Electronics Show 2015 as well. Thanks to organizers at KES for such a great exhibition. Special thanks to marketing team and JONES Korean team for supporting. See you next year, KES!
