Acrolab has been engineering cooling solutions for over 70 years.  Our team evaluates your current challenges to bring you the best engineered cooling solution possible.  Based on our extensive history and knowledge base, multiple proprietary technologies can be utilized to develop the most optimized solution for your application.  Our range of applications span temperature ranges from cryogenic (-150°C) to super heated (800°C).

Some of our application solutions include:

Heat sinks, cooling plates, Isobar heat pipes, vapour chambers, fluid cooling systems, air cooling systems, cooling platens, cooling blocks, cabinet cooling, tool and mould cooling, parts cooling and support services that include engineering, prototyping and thermal simulations.

Isobar® Technology Achieves Uniform Cooling for Plastic Injection Molds

In the plastic injection manufacturing process our Isobars® can effectively enhance the capabilities of heat transfer from the tool surface to the cooling media, resulting in a much more cost-effective and efficient process.

Not only does this allow for a more optimal design of the cooling system, it also reduces hot spots and minimizes scrap caused by warping or under-fill.

The mold’s thermal properties are dependent on the quality of the tool steel used and can significantly affect the heat transfer of the molten plastic as it is injected into the mold.  Acrolab’s cooling systems are proven to be extremely effective at reducing cooling times both locally and generally. The thermal conductivity of tooling steel used for most injection molding applications is limited due to its inherent physical attributes, however, an engineered Isobar heat transfer system can significantly improve the thermal performance of plastic injection molds

Isobar® Mold Cooling Solutions Include Custom Built Baffle Isobars

Accelerated cooling is a result of the addition of baffles to our standard Isobars®.  The ability for Acrolab to provide custom built baffle Isobars to replace your standard baffles designed into your cooling circuit will noticeably increase the overall cooling rate in the plastic injection process.  The enhanced performance of baffle Isobars is related to the same rapid, two-phase heat exchange provided by standard built Iosbars and requires no additional work on behalf of your design team, just add them to your bill of materials.

Isobar® Heat Transfer Technology and Conformal Cooling Solutions

As is the case in many tool, die and mold applications, complex geometries are difficult to address with respect to sufficient cooling channels and channel access to inserts and slides inside the mold.  The channel cross section is again circular, which can result in problems where the distance of the edges of cooling channel to the mold surface is not consistent, resulting in uneven cooling.

By considering Acrolab’s conformal cooling products and Isobar technology into custom additive manufactured tools, inserts and slides, moldmakers and processors can now achieve the next level of cooling performance.  Benefits presented by additive manufacturing technologies, and more specifically the enhanced performance of conformal cooling made possible by Acrolab’s innovative technologies, can be implemented with your team to create the optimal design for your next project.

Isobar® Heat Sink: The Alternative for Cooling Electronics

The Isobar® Heat Sink works using natural convection by taking advantage of the Isobar® Heat Pipe’s ability to transfer and dissipate heat efficiently and effectively. It offers low thermal resistance and high power capability – a superior benefit for modern electronics operating at or over the 100-watt level.

The Isobar® Heat Sink consists of three basic parts:

  1. Heat input plate, which is fastened to the electronic;
  2. Isobar® Heat Pipe(s), which transfers the heat from the heat input plate to the fin stack; and
  3. Fin stack, a group of fins that dissipate the heat into the air.

Isobar® Heat Sink Benefits

• Ability to transport heat at a high rate over considerable distance with extremely small temperature drops

• Constructional simplicity

• Exceptional design flexibility

• Requires no external power (passive two-phase heat transfer)

• Makes efficient use of space

Isobar® Cooling Modules

Acrolab’s high efficiency Isobar® Cooling Modules are capable of dissipating up to a 120 watt load with a 12°C temperature drop. Isobars carry heat to the cooling fin stack, where it is dissipated to the surrounding air by forced convection. Cooling modules offer low thermal resistance and high power capability. Isobars manufactured by Acrolab are typically copper, copper wick or sintered wick and water charged design that operate in any orientation.

Analysis of the Performance of a Cooling Chamber for Pre-Preg Manufacturing

  • Challenge: To analyze the performance of the cooling chamber for one of our customer’s pre-preg manufacturing machines and to provide recommendation on how to improve it.
  • Application: Carbon Fiber Pre-Preg Manufacturing.

Acrolab analyzed the performance of the cooling chamber inside a pre-preg manufacturing machine and provided modifications to the design to improve it. A detailed report summarizing the findings and recommendations to the machine build was proposed and sent to the client. This solution solved their cooling problem on their new prototype pre-preg machine.

Development of Cooling Tunnel

  • Challenge: To develop an industrial part washer system, with an engineered solution focused on the cooling tunnel design that would ensure that the automotive engine parts were sufficiently cooled prior to the next process.
  • Application: Automotive Metal Engine Part Production.

The objective of this case was to develop an engineered solution for the cooling chamber as part of a complete industrial part washer system. Acrolab engaged one of our technology partners to assist with the project and we completed a detailed heat transfer analysis on the cooling system.

Our Vapour Chamber Technology Achieves Rapid Uniform Tool Face Heating or Cooling in Composite Processing Tools & Dies

Acrolab’s vapour chamber technology utilizes the principle of a two-phase, evacuated heat exchanger. An evacuated and sealed void within the die under the mold is machined so that the void extends to a constant wall section below the mold face. Working fluid is then introduced into this void. This innovative application of using a two-phase, evacuated heat exchanger concept causes the vapour to transfer the latent heat within the void uniformly to the tool working face.

The Introduction of a Cooling Coil Achieves Uniform Rapid Cooling of the Mold

Acrolab’s unique cooling systems for material processing applications enhances the thermal performance of your molding platform. Accelerated cooling is achieved by integrating one or more technologies that typically complement your existing systems and equipment. As an example, for one of our standard manufacturing applications we offer a hybrid solution; fluid is pumped through an embedded  coil inside a chamber, removing the heat and causing the mold working face to cool rapidly.
