Vecow WCS: water cooling solutions for GPU computing systems

GPU computing systems increasingly adopted in the industrial field

In recent years we have witnessed in the industrial field an increased usage of GPUs for tasks that go beyond graphics, such as parallel computing or inference in systems exploiting AI algorithms.

Often, systems developed to host one or more GPUs absorb a large amount of electricity which is transformed into heat, that must be dissipated into the environment by means of a suitably sized thermal solution, to guarantee optimal operating temperatures and operational stability.

How to handle heat, the biggest enemy of hardware

In the industrial field, depending on the type of application, the choice of the thermal solution falls into one of these three types, each characterized by advantages and disadvantages.

Vecow’s solution

For the GPC-1000 and RCX-1500 systems, where can be installed up to two full-size GPUs with 300W TDP, Vecow offers a liquid thermal solution as an alternative to the traditional active air coling. Both open loop and closed loop solutions can be configured.

Open-loop solutions have the same mechanical dimensions as the respective air-cooled solutions and use coolant provided by an external system to cool down CPU and GPU. In this configuration, the hardware of the PC is isolated from external contaminants and maintenance level is similar to the one required by a passive convection thermal design.

Closed-loop solutions have a larger footprint than air solutions. They embed in a single case, but in a separated section from the electronical boards, all the hardware for liquid recirculation and cooling. This kind of solution, although less performing than the open-loop one, allows to extend system’s operating range up to 20% and to reduce the operative temperature by 10%, when compared to the respective air-cooled counterpart.
