Brahmans trailers [1] conducted simulations of heat transfer tubes within the panel heating method by Finite Element. To find the temperature distribution at various positions. A replica of the heat pipe panel size. 80x282.5x350 mm. The group of inner tubes arranged in a horizontal overlap diameter 10 mm, the model boundary conditions. The temperature at the inlet is equal to 20 degrees, 25 degrees, 30 degrees and 35 degrees respectively, the model determines the temperature on the surface of the panel casing provides constant heat at 50 degrees, 60 degrees, 70 degrees. 80 degrees respectively insulated by the wall. (No heat loss), the results showed that temperatures will increase the value, respectively, and the rates are rising steadily. And over time, the temperature of the interior of the model is constant. After that, no matter how much more time will be added. However, the temperature at different locations. Internal models are unchanged
Ma Jun Kun et al [4] conducted heat to flow through channels parallel with triangular fins. To optimize heat transfer in a parallel flow channels with triangular fins. The heat transfer constant (constant heat flux), this project considering the ratio of the height of the fins to distance heating (e / D) is equal to 0.125, 0.187 and 0.25 Deployment fins are placed. directly opposite each other Pitt and is still equal to 20 mm in 2.1 images
from the experiment. The increase of the ratio of height triangle fin spacing on a sheet of parallel channels (e / D) is equal to 0.125, 0.187 and 0.25 can optimize 1.58, 2.28 and 2.32 at the plate fin in line. The fins placed opposite each other can optimize 1.62, 2.25 and 2.28 respectively hypothesis that. The heat even more. The pressure drop occurs, they have increased as well,
the currency fell et al [5] The experiment of heat transfer in laminar flow through channels parallel with fins placed V-shaped with heat. Static (Constant Heat Flux) education will be considered. The ratio of fin height to distance plates (e / D) and formatting fins affecting coefficient. Heat transfer (Nusselt Number) and coefficient of friction (Friction factor) The scope of the study, the number Ray Arnold (Reynold Number) range between 500-3000 proportion height fin the distance plate channel. Parallel heat (e / D) is equal to 0.20, 0.25, 0.33, organize and fins placed opposite each other. Pitts and Mike constant equal to 40 mm by 2.2 images
from the experiment. The V-shaped arrangement of rectangular fins to transfer heat more than the placement of the cross fin (transverse rib) an increase in the ratio of fin height to distance plate. Parallel channels (e / D) can be optimized to increase heat transfer. But the pressure drop that occurs, there will be increased as well,
and the density [6] conducted a study of heat transfer in a tubular heat exchanger to increase. But the pressure drop occurred. There is increasing as well,
and the density [6] conducted a study of heat transfer in a circular pipe installation kit creates turbulence and swirling flow. Heat from the implant cone ring creates turbulence and swirling flow. Heat from the implant cone ring created a stir with twisted sheet flow generated by the rotation of the tubular heat stabilizers. In experiments cone ring implant length tube with a diameter of the hole entrance and exit is 46 mm (D) in the experimental implant sheets twisted length pipe made from sheet steel 1 mm and lead. The twist at the second pitch is y = (p / w) = 3.75 and 7.5 respectively in the air flow and test the Ray Reynolds number (Re) 6000 -26 000 of which were from there. The air inside the pipe caused a stir and flow spiral makes up the skin and delay the flow in the pipe longer, so the heat in the form of numbers Nasser Celt (Nu) increase compared to the pipe. is about two to four times as high as the friction. The results showed that the implant cone ring with narrow twisting term sheet twists at y = 3.75 to the maximum number Nasser Celt and more twisted-term average of y = 7.5. 12%
of research in the past focused mostly equipped with fins (Ribs) ways to enhance the heat transfer of heat exchangers. But what followed was the friction that occurs. This is what should happen to a minimum due to the power consumption of power. The cost of installing the system and more. To get the flow rate of fluid required by the nature of such work
, this project is focused on the heat exchanger plate grooving internal heat exchanger to reduce the friction of the fins as air. Plate heat exchangers (Plate Heat Exchanger) but still has the ability to heat well. EDUCATION Experimental between aluminum sheet and aluminum tumbled another term.
