Bonded fins heat sinks

Hereby we'd like to introduce our bonded fins heat sinks. 

1.Bonded fin heat sinks are an assembly of a grooved base with individual fins bonded into the grooves. The fins are inserted into the base grooves and are joined by epoxying, brazing, or soldering.





2.Bonded & Brazed Fin Heat Sink Product Details:
(1).Materials:
Aluminum
Copper
Stainless Steel
Inconel

(2).General Design Guidelines:
Fin thickness typically ranges from .010” to .080” (other thicknesses as needed)
Brazed, soldered or thermal epoxy bonded depending on thermal resistance required
Fins can easily be non-uniform geometry, especially length, with no post machining

3.We provide one-stop thermal-management solutions, from R & D, thermal simulation to manufacturing, products include Bonded Fin Heat Sink, Skived Heat Sink, Pin Fin Heat Sink, Extrusion heat sink, Heat Pipe Heat Sink, Water cooled heat sink, Liquid Cold Plate www.jacarlosworld.com

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

Rail Traction System、Hybrid /Electric Vehicle (HEV/EV), Auxillary Vehicle Systems

* Others

 Industrial frequency conversion、Industrial Motor Controls、Medical Device、Laser Equipments.

(2).Maximum heat dissipation under forced convection (with high airflow)
(3).No interface joint (or thermal resistance) between the fins and base
(4).High aspect ratio (up to 50)
(5).Easy and inexpensive to prototype
(6).Low  tooling costs
(7).Short lead time
(8).Can have embedded heat pipes to further boost performance
(9).Anti-oxidation surface treatment helps extend serving time

Vapor Chamber

A vapor chamber is essentially a flat heat pipe that can spread heat evenly in two dimensions. It consists of a hollow copper shell that has an internal wick structure to transport the fluid to the heat source and a vapor area for the transport of the vapor away from the heat source. The entire chamber is operated under vacuum so that the operation fluid (water) vaporizes at room temperature. This is how the vapor chamber very efficiently transports heat evenly across the surface of the condenser, allowing all the fins to work as hard as the ones that are over the center of the heat source. The vapor chamber performance will increase over that of a metallic heat sink the larger the base area and the smaller in the heat input. 



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.
