Increasing Temperature

This paper specifically addresses the effect of the sintering temperature curve in manufacturing nickel powder capillary structure (wick) for a loop heat pipe (LHP) with flat evaporator. The sintering temperature curve is composed of three regions: a region of increasing temperature, a region of constant temperature, and a region of decreasing temperature. The most important region is the increasing temperature region, as the rate of temperature increase directly affects the performance of the wick.When the slope of the region of increasing temperature is 0.8 (equivalent to 8 OC/min), the structure of the manufactured wick is complete, with the best heat transfer performance result. Experimental resultsshowed that the optimal heat transfer performance is 160W, the minimal total thermal resistance is approximately 0.43OC/W, and the heat flux is 17W/cm2; the optimal wick manufactured has an effective pore radius of 5.2 μm, a permeability of 5.9×10-13m2, and a porosity of 64%.

Working Medium

The principle of the proposed device is to use part of the waste heat, which otherwise leaves through the chimney unused into the air, to preheat the combustion air. reducing chimney losses and preheating the combustion air will increase the efficiency of the heat source. the device is actually a gravity loop heat pipe with an evaporating part located behind the furnace and a condensing part in the combustion air supply duct. Heat transfer is realized by means of phase transformation of the working medium in the proposed device.
