Two-Phase Heat Transfer Technologies
Two-Phase Heat Transfer Technologies are the cornerstone of Novark's product line. There are numerous applications of two-phase fluid flow technologies in a variety of industries. They are also are a key component of most thermal management solutions. These technologies feature much higher thermal conductivity than solid copper and near-uniform temperature gradients, essential for effective thermal management devices. Two-Phase Heat Transfer Technologies are differentiated across their numerous applications by the structure of their wick, the working fluid used, and their shape.
Ultra-Thin Heat Pipe
The ultra-thin heat pipe is formed either by flattening a thin-walled standard heat pipe with a wick structure in between. The wick structure is either a sintered copper powder section on one side of the heat pipe wall, or a copper wire mesh or fiber sintered in the center of ...
Finned Heat Sinks
Heat Sinks are the primary means of forced-convection heat dissipation in thermal management solutions, and are one of Novark's core products. Heat Sinks are differentiated by the method of manufacture of their fins, which define their cost and thermal performance.
Cold plates are the liquid-cooled heat dissipation method of choice, and are an important product in Novark's thermal solutions. Cold plates are defined by their method of manufacture, which defines their performance and application.
Vacuum-Brazed Cold Plate
Vacuum-brazed cold plates are created by machining two metal plates with interior channels and fin structures (often folded fins and skived fins), which are then carefully sealed together inside a vacuum chamber. A filler metal with a lower melting point is melted into the joi...
Novark Technologies pushes its design and manufacturing capabilities forward every year. The following technologies have been successfully prototyped at Novark Technologies, and Novark attempts new techniques and technologies on a consistent basis.
Pulsating Heat Pipe
Pulsating heat pipes are made from a long capillary tube which is bent multiple times, or from a rectangular plate with capillary channels manufactured in it. The bends are placed at the evaporator and condenser areas of the heat pipe. This type of heat pipe does not require a...
