absorber plate การใช้

• Heat is transferred from the absorber plates of the collector in the fluid by conduction.
• They consist of an absorber plate which air passes across or through as it scrubs heat from the absorber.
• One way around this is to simply use the same material for both the piping and the absorber plate.
• Based on absorber plate area, most evacuated tube systems are more efficient per square meter than equivalent flat plate systems.
• Heat and infrared radiation ( IR ) are produced when short wave radiation light hits the absorber plate, which is then trapped inside the collector.
• Evacuated tube collectors have a lower absorber plate area to gross area ratio ( typically 60 80 % of gross area ) compared to flat plates.
• Prasad and Saini [ 1988 ] conducted experiments by varying the relative roughness pitch in the absorber plate and observed that the flow pattern downstream the ribs was a function of the relative roughness pitch.
• Copper is used both in receivers and primary circuits ( pipes and heat exchangers for water tanks ) . but there may be similar problems with the heat transfer between the absorber plate and the pipes as well.
• Where " C 0 " is the collimation factor ( what fraction of the explosion plasma debris will actually hit the impulse absorber plate when a pulse unit explodes ), " V e " is the nuclear pulse unit plasma debris velocity, and " g n " is the standard acceleration of gravity ( 9.81 m / s 2; this factor is not necessary if " I sp " is measured in N穝 / kg or m / s ).
