Tomorrow's Kitchen 3548360Cool Plate

Product Information

These cold plates are generally used for high-performance designs that require low thermal resistance, and superior leak-free reliability. They enable designers the greatest flexibility in specifying such criteria as thermal resistance, thermal flow, pressure drop, fluid path, size, shape, material hardness, surface geometry, and the ability to mount components on both sides of the plate. The internal features can be created by machining flow guides and fins from the base metal or by introducing high-performance corrugated aluminium-fin.

Z T = ( α 2 σ T ) / κ {\displaystyle \mathbb {Z} \mathrm {T} =(\alpha The next step beyond an open-air environment is to use a controlled atmosphere under normal or close-to-normal atmospheric pressure. In this type of environment, a high degree of control over the overall process can be achieved and open-air issues of oxidation, scaling and carbon buildup can be virtually eliminated.

Key mechanical property predictions, including yield strength, ultimate tensile strength, elongation, and hardness Each bank includes an independently driven edge masking system on each side of the cooling machine, preventing overcooling which may lead to the poor flatness of the plate following the cooling process. Head and Tail Masking The extremities of the product may become overcooled due to additional water flowing across the top surface or from the rolling process itself. During the head and tail (H/T) masking, the water flow reduces by a predefined level and distance along the material to compensate for this additional cooling. Feedforward Control Abrasion-resistant steel requires temperature control and flatness to achieve the correct microstructure. Cooling conditions can vary during rolling and result in nonuniform temperature profiles of the plate. Despite these challenges, the inline cooling technologies from Primetals Technologies demonstrated the successful application of direct quenching and temperature control to produce ideal and targeted surface microstructures directly after rolling, translating to the necessary hardness and toughness for demanding steel grades. This is a two piece construction. The liquid flow path is CNC machined into the base. This flow-path can be complex and can even incorporate fins to enhance the heat transfer surface.

These cold plates have the advantage that there are no thermal boundaries and the aluminium plate has had no thermal stress during the manufacturing process so flatness is easier to achieve. FSW Friction stir welded (Liquid cold plate) Industry-wide, the use of inline plate cooling technologies has proven to be essential to producing high-strength steel grades. Recently, producers have focused on decreasing their environmental impact and lowering operational costs by reducing post-processing requirements and carefully monitoring and managing water consumption. To this end, the specialists and experts at Primetals Technologies developed the MULPIC system, a comprehensive system for inline plate cooling providing unparalleled control over the plate cooling process. What is inline plate cooling? Crossbow” and “canoe” are common flatness defects for plates. By independently setting the flow from each top and bottom header, individual flow control valves can help limit these defects. Selecting the flow ratio can compensate for differences in the water-to-material heat transfer coefficients for the top and bottom surfaces. Edge Masking Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current. Such an instrument is also called a Peltier device, Peltier heat pump, solid state refrigerator, or thermoelectric cooler ( TEC) and occasionally a thermoelectric battery. It can be used either for heating or for cooling, [1] although in practice the main application is cooling. It can also be used as a temperature controller that either heats or cools. While the MULPIC system consists of a cooling machine featuring precision valve control and an advanced automation system, a process model, or “digital twin,” allows for the integration of historical data, real-time information, and model adaption to impact the efficiency of continuous operation.Dependent on the required thermal performance and the cooling fluid to be used the tube can be copper or stainless steel and can be a simple mechanical (dry) press fit, press fit with a thermal epoxy boundary to eliminate micro voids or soldered in place for maximum thermal performance. Gun Drilled (Liquid cold plate) Brazing in a high vacuum environment provides the most process control and produces the cleanest parts, free of any oxidation or scaling. It is the preferred brazing environment for brazing aerospace components, hardening medical devices and other applications that require the absolute highest part quality. Liquid cold plate solutions are currently deployed in: Renewable Energy Systems, Traction Systems, Medical Equipment, IGBT and Power Semi-Conductor Systems, Lasers, Data Centres, Industrial Power Applications, Defence Systems, Avionics, Fuel Cells, Battery Cooling and many more High Power and High Heat Flux Applications.

Image of Cold Plate with the upper layer made transparent. This shows the flow path, in this case designed to perform like a Bubble Plate Each top header contains three chambers, with the flow controlled by a crown valve. The water flow density is uniform across the width of the fully open valves. As the valves are closed, the water flow to the end chambers lessens, and a water crown forms. One should note that crown control increases in importance as the plate width increases. Top/Bottom Flow Ratio By recalculating the required flow at every meter along the plate length, feedforward control compensates for variations in the incoming product temperature. Availability and Maintenance Improvements Flatness and yield are two key performance indicators that contribute significantly to the overall efficiency of the production of steel plates. Rectifying flatness defects requires post-processing, such as cold leveling, so the ability to control and optimize flatness during cooling is an essential feature of the technology. Improving yield from a plate means that less steel is needed to produce the equivalent final product, saving energy and emissions. During cooling, the final temperature uniformity, which influences mechanical property distribution in longitudinal and transverse directions, significantly impacts yield. The MULPIC system includes several actuators specifically designed to improve both the flatness and the yield and to control cooling with precision: Cooling flatness control actuators Crown Control

Brazed (Liquid cold plate)

The "hot" side is attached to a heat sink so that it remains at ambient temperature, while the cool side goes below room temperature. In special applications, multiple coolers can be cascaded or staged together for lower temperature, but overall efficiency (COP) drops significantly. The maximum COP of any refrigeration cycle is ultimately limited by the difference between the desired (cold side) and ambient (hot side) temperature (the temperature of the heat sink). The higher the temperature difference (delta), the lower the maximum theoretical COP. A gun-drilled cold plate is manufactured by drilling a series of holes through the length of an aluminium plate to form multiple flow paths. When applying plate cooling technology, the benefits for steel producers are abundant, including improved cost efficiency, reduced environmental impact, increased product versatility—i.e., from structural grades to abrasion-resistant steel—, leaner manufacturing, and enhanced quality and productivity. However, previous accelerated cooling technologies were without recent developments in automation and digitalization, which now take each of these improvements one step further. Primetals Technologies has combined its competencies in mechatronics, automation, and digitalization solutions to create the MULPIC system for inline cooling.
