Each manufacturing technique has advantages depending on the liquid cold plate design, the manufacturing volume required, the choice of cooling liquid, pressure drop requirements and the financial budget of the customer. Typical Applications for Liquid cold plates

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. The impact of accelerated cooling on plate production is immediately visible regarding reduced manufacturing time. For example, direct quenched (DQ) or abrasion-resistant steel plates require specific processing that traditionally utilizes reheating, quenching, and tempering to reach the necessary hardness, toughness, work-hardening, and ductility required. Producers of high-strength steel focus on these characteristics because abrasion-resistant steel is essential in mining, lifting, and excavation industries. Inline cooling technology is a viable solution for steel producers to achieve greater efficiency by applying direct quenching that bypasses the reheating step. Unlike previous cooling technologies, MULPIC has adapted accelerated cooling technologies to include the latest automation and digitalization technologies to realize analog improvements in plate cooling. This solution allows producers of high-strength steel to see immediate improvements in quality and yield while reducing their environmental impact. Additionally, the MULPIC system provides flexibility regarding cooling options, from direct quenching to accelerated cooling, making the cooling process more efficient. MULPIC’s Digital Twin also offers the opportunity to use real-world data in an offline testing format to ensure seamless execution of trial runs and assistance with strategy, product design, development times, and the costs typically associated with such practices. With a combined mechatronic and digital solution, MULPIC offers the opportunity for steel producers to lessen their environmental impact while improving production. Possibly the simplest form of cold plate where a joint free tube is embedded into a copper or aluminium carrier. Previously, hot-rolled plates cooled to room temperature before low-temperature rolling and processing—standard practice for high-strength low alloy steel grades (HSLA). Examples of processing included normalizing and annealing or quenching and temper processing. Before inline plate cooling, steel producers used these steps to tailor the air-cooled plate microstructure for final applications, for example, abrasion-resistant plates. However, with the application of inline cooling, steel producers can achieve target microstructures with temperature control for accelerated cooling and direct quenching. A schematic diagram illustrating post-rolling options with and without inline cooling technology reveals the impact of inline cooling on manufacturing time. Moreover, inline cooling offers various cooling strategies following rolling for different steel grades. Direct Impact of inline Cooling

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 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. Vaccuum brazing As the steel industry focuses on its environmental impact and producers search for ways of simultaneously improving efficiency and product quality, digitalization and process optimization are the keys to a sustainable future for steel. An analog and digital solution from Primetals Technologies focused on inline plate cooling, MULPIC, provides steel producers with a means of cooling plates in an eco-friendlier and more efficient manner, all the while reducing production costs. 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.

For the inlet and outlet fluid path, holes are drilled perpendicular to the main fluid path and then partially plugged to create a continuous coolant path. 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 MaskingBrazing 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. 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 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.
