solar flat plate Collector With Aluminum Absorber

タイトルまたは説明

Collector efficiency : *8%, a1=5.5%, a2=0.*1; Coating efficiency : absorption *5%, emission *0%; Standard coating thickness : 0.7mm Origin : China Compress structure: Yes In order to fit the request of different market, wedesigned a particular structure of aluminum fin/copper tube structure for choice. Our structure has the following advantages: <1> The aluminum fin is made by one fin but not two. Thus avoid the stress on the copper from mechanical compress. <2> The structure is good to avoid any possible electrolytic corrosion between aluminium/copper ( if ultrasonic welding between two material, the this problem will happen) <3> This structure is stronger between aluminum/ copper connection <4> Better at heat absorption, since : thicker aluminum fin there is wrinkle on aluminum fin there is more contact surface between the aluminum/copper
