The cooling mechanism of the electronics is very important because it determines the performance and life of these electronics. If appropriate cooling methods are not considered, the devices may heat up and not perform as they should.
Different cooling methods are used to ensure that these devices work efficiently and even last longer. Liquid cold plates are quite popular, and many electronic manufacturers have chosen the vortex liquid cold plate for their devices.
If you look forward to knowing more about vortex liquid cold plates, you are at the right place and you get an insight into every detail of them. So, let's read below.
The first question that might hit your mind could be what a vortex liquid cold plate is. So, well, a vortex liquid cold plate carries out the job of dissipating heat away from the components of electronic devices.
The vortex liquid plate is a metal plate that has channels like the usual liquid cold plate. However, the channels of this liquid cold plate are designed to create a whirlpool in the liquid, which improves the transfer of heat required between the liquid and the plate.
There are multiple other cooling methods too, but vortex liquid cold plates offer many advantages compared to those. It is an efficient cooling technique and offers better transfer of heat. Moreover, it doesn't clog and can be easily integrated into electronic devices.
The vortex cold plates were developed for power electronics, and after that, they have been evolving and, with massive advances, are now used for multiple applications. Electric vehicles and renewable energy systems depend highly on these systems for cooling.
In a vortex liquid cold plate, the liquid coolant moves through the channels, and the design of these channels is such that it creates swirls of fluid. These swirls enhance heat transfer between the liquid coolant and the components that need to be cooled down.
The important components of this cold plate comprise fins, vortex generators, inlet, and outlet ports and channels. The cooling process starts with the coolant entering the inlet port and then spreading through the channels, creating swirls. The fins present on the cold plate improve the heat transfer due to a larger surface area.
In the vortex cold plates, turbulence is created with the help of vortex generators, and it helps in efficient cooling. The movement of liquid through channels promotes heat transfer through vortices.
There are many advantages of using vortex liquid cold plates, and these may comprise a better rate of heat transfer, precise control of temperature, and improved performance. Moreover, the design of the vortex liquid cold plates is so simple that it is extremely cost-effective to adjust within the existing designs of the devices or placing them in the new ones.
Vortex cold plates are of different types having different designs and features followed by varied applications. These types, along with their applications, are discussed below:
One of the simplest and most commonly opted types of vortex liquid cold plate is a straight/-through one with straight channels and a vortex generator on one end of the liquid plate. The coolant in this type of plate enters from one end and leaves from the other, creating a vortex after passing through the vortex generator. These liquid cold plates are suitable applications having lower heat flux densities.
In this kind of vortex cold plate, the channels are connected, creating a serpentine flow path. This cold plate design improves the designs by having an increased contact time between the components and coolant, which also results in improved cooling efficiency. Serpentine design is suitable for applications that have high heat influx densities.
In the crossflow vortex liquid cold plates, the flow path is perpendicular to the electronic components, offering a high level of cooling. It is also suitable for applications with high heat influx densities like serpentine.
As the name suggests, this kind of vortex cold plate has many pins or fins on the surface of the cold plate. The pins create turbulence in the coolant, and heat transfer with better cooling efficiency occurs. It is suitable for cooling in components where space is limited.
When vortex cold plates are designed, some factors need to be taken into consideration, and these may include the following:
● Flow rate is one of the primary considerations because it determines the ability of the cold plate to transfer heat. Hence higher flow rates are always better for the vortex liquid cold plates.
● Pressure drop must also be considered because it is the resistance to flow, and if the pressure drops get higher, the heat transfer rate is also high.
● The size and number of fins also have an impact on the cold plate and its ability to transfer heat. When the fin density is higher, the surface area also increases; hence heat transfer improves.
● The shape of the vortex cold plate also determines the performance of cold plates; if the plate is thin, the thermal resistance lowers.
● The properties of coolant, like its density and viscosity, also impact the performance and hence needs to be considered.
● While designing the cold plate, the conditions in which it will be operating should be taken into account because, according to the conditions, the features of the cold plates are designed so that it may handle them in the longer run.
The maintenance and cleaning of vortex liquid cold plates is also a matter to consider, the power must first be disconnected, and the liquid should be drained. Now, if any accumulated dirt should be removed and using a soft brush, the fins need to be cleaned.
You can use a mild cleaner to wipe the cold plate and rinse it with distilled water. You can now fill in the liquid and reconnect it to the power. Keep an eye on the leakage, if any, and keep monitoring its performance from time to time.
