Mechanically pumped Loop
To integrate a TCS into a CubeSat, it needs to be low-cost, physically small, low in power consumption and both modular and flexible. As a robust solution for this, Royal NLR developed a new thermal concept, the mini mechanically pumped loop (MPL). It transports the heat dissipated at hot spots to thermal radiators where the heat is radiated away into space. The heart of the system is the multi-parallel micro-pump (MPMP), which provides a low-mass MPL solution with high reliability due to multiple pumps in parallel for generating the flow. This design avoids the single point of failure of one pump in the loop. The individual micro-pumps are piezo-driven displacement pumps with passive micro-valves. The flat design allows similar performance both on the ground and in micro-g operations in space.
