“…A lowercost solution is the use of heat pipe-embedded heat sinks (HPeH) that, when properly designed, perform similarly to heat sinks with flat heat pipes, which can effectively reduce the thermal resistance of diffusion while having the advantages of low cost and simple process. Song et al [20] embedded a heat pipe into the bottom plate of a traditional radiator, and the maximum temperature of a heat source was reduced by 15 • C compared to that of a conventional radiator. Wang et al [21] studied the cooling performance of a heat pipe embedded in the bottom of a radiator with different arrangement and its influence on the temperature distribution of a CPU.…”

Conventional straight fin (SF) radiators have difficulties meeting the cooling requirements of high-power electronic components. Therefore, based on the structure and technology of the detachable fin radiator, this paper proposes a kind of radiator embedded in the heat pipe base and uses the roll-bond flat heat pipe (RBFHP) to replace the traditional fin. The radiator has the advantages of modularity, easy manufacturing, low cost and good heat balance. In this study, the heat pipes (HPs)-RBFHPs radiator was tested in natural convection and forced convection to mimic the actual application scenario and compared with the conventional aluminum radiator. Heating power, angle, wind speed and other aspects were studied. The results showed that the cooling performance of the HPs-RBFHPs radiator was improved by 10.7% to 55% compared with that of the SF radiator under different working conditions. The minimum total thermal resistance in the horizontal state was only 0.37 °C/W. The temperature equalization of the base played a dominant role in the performance of the radiator at a large angle, and the fin group could be ineffective when the angle was greater than 60°. Under the most economical conditions with an inclination of 0° and a wind speed of 2 m/s, the input power was 340 W, the heat source temperature of the HPs-RBFHPs was only 64.2 °C, and the heat dissipation performance was 55.4% higher than that of SFs.

In this preliminary investigation, we analyzed the possibility using a stainless steel foam as a wick material in heat pipe. The heat pipe will be used as a passive cooling sytem in electronic devices. Stainless steel foam that used in the current investigation is a commercial foam that has been treated to be characterized using SEM and 3D optical microscope. Analytical models were also developed to calculate the capillary pressure and effective thermal conductivity of the stainless steel foam. The analytical model revealed that the optimum stainless steel foam to be used as wick material is found at the pore size, porosity and contact angle of 30 μm, 0.1 and 0°, respectively.

Summary In a low‐carbon economy, nuclear energy is considered a viable option to meet increased energy demands. Several countries have been developing sodium‐cooled fast reactors (SFRs), which have a highest potential for commercialization among Generation IV reactor systems. However, for SFR's safe operation, the gas entrainment (GE) issue in SFRs should be resolved first. Although many types of free‐surface stabilizers have been studied for preventing GE, any generalized types showing a stable operating performance have not been determined yet. In this study, as a new type of free‐surface stabilizer, we have tested a magnetohydrodynamic (MHD) stabilizer for the Korean‐conceptual SFR. A pair of torus‐type magnets was devised for the MHD stabilizer through parametric‐model studies. The magnetism well alleviated the sources of GE such as the rotating flow and central sink. As a result, a calm free surface was achieved with an 87% reduction in vortex core depth using 0.07 T magnetic field intensity.
