Product Information

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 This technology is ideal for prototypes and small production runs as no tooling investment is required. 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. 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?

Multiple internal and external features can be incorporated into the two Die Cast tools. After casting the two halves can be bonded together by welding or by the use of an epoxy. Brazed (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. 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) 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. Key mechanical property predictions, including yield strength, ultimate tensile strength, elongation, and hardness

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 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 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.

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) 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. Direct quenched (DQ) or abrasion-resistant steel plates on a cooling bed Near-surface optical micrograph taken from a test sample of direct quenched (DQ) or abrasion-resistant steel plate Introducing MULPIC 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 By recalculating the required flow at every meter along the plate length, feedforward control compensates for variations in the incoming product temperature.
