Thermoelectric self-cooling was firstly conceived to increase, without electricity consumption, the cooling power of passive cooling systems. This paper studies the combination of heat pipe exchangers and thermoelectric self-cooling, and demonstrates its applicability to the cooling of power electronics.Experimental tests indicate that source-to-ambient thermal resistance reduces by around 30% when...
The green hydrogen is meant to be the next generation heat carrier. It is the storage solution of the renewable energies that lack of manageability. In this work, the feasibility of substituting the conventional purity phase of a 50 kW alkaline water electrolyser for a thermoelectric refrigerator (TER) is studied. The TER reduces the temperature of the hydrogen flow to the dew temperature where the...
The heat dissipation systems which have liquids as heat carriers outperform conventional dissipation systems at TEGs (thermoelectric generators). However, new elements need to be introduced such as pumps, secondary heat exchangers and piping.A predictive computational model of a dissipation system involving refrigerant liquids has been implemented. The accuracy of the model is 93% for all its outputs:...
Kefir is considered to be probiotic, beneficially affecting the host through its effects in the intestinal tract. Despite numerous studies that have examined the actions of probiotics on the host organism, few have analyzed the effects on intestinal enzymes. The aim of this present study is to report data on the effects of kefir on enzymes and proteins present in the intestine. In this study, female...
