THERMAL MANAGEMENT PRODUCT AND SERVICES

Thermal Management Consulting

CoolJag has a staff of thermal engineers who are decidedly competent in both CFD (Computational Fluid Dynamics) and heat transfer analysis. They are fluent in many commercial CAD platforms and have the capability to create or modify computational code as required.

Whether it’s a simple heat sink extrusion or a high-capacity complex-channel cold plate, our engineers can develop a solution that meets or exceeds your thermal performance requirements.

Product Testing

Testing is an essential part of developing any quality product. It helps engineers, designers & manufactures create products that reliably meet or exceed technical & performance requirements, as well as quality & safety standards.

The end result are high quality performance products that last.

One objective of the test design & its execution is to anticipate the worst-case scenarios in which the product will be used and simulate those conditions. Under those conditions, it is meeting or exceeding performance requirements that proves the product is ready for market.

In addition to CoolJag's extensive experience and knowledge base that is put to task during the product testing process, we utilize many specialized tools as well. These include:

1. Thermal performance measuring & monitoring equipment
2. High accuracy thermal reference loading
3. Thermal cyclers
2. Wind tunnel
3. Load cells
4. Flow metering & monitoring
5. Leak tester ( Gas: N2)
6. TEC test equipment
7. Environmental temperature & humidity controls

Manufacturing

CoolJag is truly a turnkey product manufacturing company. We have just about every tool & process in house that could be required to build any product within our field of expertise.

Castings, Extrusions, CNC Machining (including 5-Axis milling), Stamping, Skiving, Friction Stir, Brazing, Heat Treating, Plating, Testing and Inspection.

There's not much that we cannot make!

Prototyping

A prototype, as it applies to CoolJag products, is an early version of a part or assembly built to test a concept or process and to act as a thing to be replicated or learned from.
Typically, we develop prototypes within a few different frameworks:

• Proof of concept
• Working Prototype
• Functional Prototype

Depending on the development goals, a prototype framework is chosen & a plan is assembled to decide on everything from materials, included features (if different from intended final design), test methodology, etc.
A prototype can be as simple as a 3D printed part that will eventually be machined or cast.
A prototype can be as complexed as using advanced materials and processes to create what is expected might be the final product if all testing goes well.
At CoolJag, we are experts in all facets of the prototype process and can help to most efficiently and effectively bring a concept to production reality.

Engineering & Analysis

When designing a thermal control system, there are myriad aspects to consider & challenges to overcome:

• Heat generation rate
• Heat transfer rate
• Heat dissipation rate
• System heat reject
• Temperature differentials
• Materials
• Fluids
• Gases
• Volume rates
• Flow rates
• Contact Surfaces
• Space constraints
• Environment
• And the list goes on…

To pull together all the relevant information, asses it, analyze it and develop the best solution requires requisite skills, experience and excellent tools. In all cases, there are tradeoffs to consider and multiple approaches to a solution. CoolJag navigates these complexities in order to arrive at the solution that most effectively achieves the thermal performance objectives.

CoolJag leads the industry in experience, skilled engineers & technicians, and utilizes the latest CAD design and CFD software available.

Thermal/Mechanical Advantages of a cold plate solution

When convection cooling isn’t capable of removing the heat load necessary to keep electronics safe, single phase liquid cooling can provide the high capacity performance required to get the job done. Liquid-cooled cold plates are the next level for high heat flux or high power electronics cooling applications.

Heat from the device(s) is transferred to a single-phase liquid coolant circulating through internal channels of a cold plate and subsequently rejected downstream to a radiator or chiller.

  • Fluid Stability
  • Temperature Uniformity
  • Weight / Size
  • Maximum Temperature
  • Pressure drop
  • Liquid flow path
  • Flow balancing
  • Material compatibility
 
DESIGN AND ANALYSIS

When designing a cold plate there are several challenges to overcome in order to create an optimal design. In many cases there are trade-offs between design options. CoolJag has significant experience in mitigating these challenges while meeting thermal perfomance objectives.

COLD PLATE DESIGN

There are a multitude of types, and infinite shapes & patterns to the flow channels possible inside a liquid cold plate. These are achieved through a multitude of processes and combination of processes such as:

Milling, Skiving, Embedded Tubes, Wire EDM, Gun Drilling, Welding, Friction Stir, & Bonding.

The infinite patterns can vary from simple single pass parallel channels to complex, interwoven serpentines; from high density fin arrays to micro-channels.

Each design will have its strengths, weaknesses and tradeoffs. From shear thermal performance and capacity to cost and manufacturability, there are many factors to consider.

This is what CoolJag excels at.
