Single-row fin width is 13.6mm, and same column copper pipe hole centre-to-centre spacing is 21mm, and the adjacent copper pipe hole centre distance of adjacent column is 17.2mm.
A kind of heat exchanger is equipped with the air-condition heat exchanger fin of technique scheme.
The present invention is optimized design and improvement for the needs of enhanced heat exchange to the fin pattern, proposes novel heat exchanger fin structural shape, in the hope of obtaining higher heat exchange efficiency.
Than existing air-condition heat exchanger corrugated fin and slitted fin commonly used, fin of the present invention can increase the contact area with air intake, and can destroy the boundary layer of air intake in fin surface formation, increase the disturbance of air intake, the speed and the collaborative degree of thermograde of air intake are strengthened, thereby improve heat exchange efficiency.Because parameters such as the position of each bridge type projection of fin and length are selected appropriate, the windage that air intake flows increases few, has therefore improved the heat exchange property of heat exchanger greatly, and then has improved Energy Efficiency Ratio.Our experiments show that heat exchange efficiency improves 6-11%.
The present invention has the following advantages and good effect: the heat exchanger with fin of the present invention can improve exchange capability of heat and complete machine Energy Efficiency Ratio, thereby the heat exchanger overall dimensions can correspondingly diminish, cost has decline by a relatively large margin, also because the arrangement position of suitable rising height of bridge sheet and long and short bridge sheet relation, make windage reduce greatly, and condensation water is dripped easily, take into account outdoor heat exchanger of air conditioner frosting problem simultaneously, make fin structure be more convenient for defrosting.
