Inner Grooved Copper Tube (IGT) Cold Plate improve 30% cooling performance
Due to the increase in internal surface area of inner grooved copper tubes, the thermal conductivity is improved by 20 to 30% compared to bare tubes.
There are several main specifications for tube diameters, including 12.7mm, 9.52mm, 7.94mm, 7mm, 6.35mm, and 5mm, among which 9.52mm and 7mm are the most commonly used.
The IGT Cold plates are widely used in:
* Electric power transmission
High voltage direct current transmission(HVDC)、HVDC Flexible、IGBT、SVG、etc.
* New Energy
Power Converters、Wind power generation、Wind Turbines、Solar Inverters, etc.
*Transportation

Vapor Chamber
Vapor chambers offer superior thermal spreading performance over traditional solid metal heat spreaders by taking advantage of two-phase liquid/vapor transport. Their lower weight and height over traditional solutions couples with their high thermal conductivity to give extremely low thermal resistance in-plane as well as through the thickness of the vapor chamber. Vapor Chambers are best suited for components with high heat densities (larger TDP in small chip sizes) which need to spread their heat to a larger area heat exchanger to achieve safe operating temperatures, thereby providing extended life and reliability for components and applied products
Vapor Chambers are designed to provide critical thermal solutions in the most limited spaces. One of the advantages of vapor chambers is that they can be used as heat flux transformer, cooling a high heat flux from an electronic chip or laser diode, and transforming it to a lower heat flux that can be removed by natural or forced convection.
Heat Pipe Heat Sink
1.Design and Modeling of Heat Pipe Assemblies
Thermal Analysis of Heat Pipe Heat Sink
Three-dimensional simulation is extremely valuable in the design of Heat Pipe Heat Sink. Because of the complex thermodynamic process (evaporation and condensation) within a heat pipe, direct simulation of physical process is difficult and time-consuming. For most engineering designs, a simple workaround is to model the heat pipe as a super conductor with a high effective thermal conductivity. The longer the heat pipe is, the higher the effective thermal conductivity should be. The assumed effective thermal conductivity shall be corrected after prototypes are made and thermal measurements are performed.
2.Assembly of Heat Pipes and Fins
Fins can be assembled onto heat pipes in two methods. One is to solder fins to heat pipes, the other is to use interference fit (also called press fit or friction fit), in which the fins have holes that are slightly smaller than the diameter of the heat pipe. By pressing the fins onto the heat pipes with pressure, the heat pipe and the fins are tightly assembled. When temperature arises in working conditions, thermal expansion of the fins and heat pipes will make the assembly even more secure.
3.Heat Pipe Heat Sinks
Heat pipes offer extremely high thermal conductivity in their longitudinal directions. Depending on the lengths and manufacturing factors, the effective thermal conductivity of heat pipes can be 10 to 1000 times of the thermal conductivity of pure copper. When coupled with highly conductive fins or spreaders, heat pipes become a powerful tool that can quickly dissipate large quantities of heat to the environment or a location where additional cooling systems can be installed.
