The contactless thermal resistance heat transfer element of W shape corrugated finned pipe of the present invention's design, heat exchanger heat transfer element than the existing split-type structural being connected by expand tube or welding manner with aluminium fin by copper pipe, aluminum pipe or micro-channel tubes is compared with heat transfer component of sharp-peak round-valley type corrugated fin-pipe, has the following advantages:
(1) heat transfer property is significantly improved.The radiating fin of the contactless thermal resistance heat transfer element of this W shape corrugated finned pipe and heat-transfer pipe adopt monolithic construction, one machine-shaping, eliminated thermal contact resistance, radiating fin is W shape ripple simultaneously, when air skims over radiating fin, flow resistance is less, and air agitation is more violent, the performance of heat transfer element is not fully exerted, thereby heat transfer property strengthens, with existing by copper pipe, the heat exchanger heat transfer element of the split-type structural that aluminum pipe or micro-channel tubes are connected by expand tube or welding manner with aluminium fin is compared, the contactless thermal resistance heat transfer element of this W shape corrugated finned pipe Coefficient K can improve 10-40%.
(2) between W shape radiating fin and heat transfer flat tube, be the angle of inclination of α (0 ° of < α <90 °), simultaneously curved, under the identical condition of heat transfer element height, compare with heat transfer component of sharp-peak round-valley type corrugated fin-pipe, it is about 2% that the area of dissipation of radiating fin increases, and the heat-transfer capability of the contactless thermal resistance heat transfer element of W shape corrugated finned pipe is further enhanced.
(3) because heat transfer property is greatly improved, transmitting under the condition of identical heat, compare with present widely used split type heat exchanger heat transfer element, the volume and weight of the contactless thermal resistance heat transfer element of this W shape corrugated finned pipe can reduce 15-39%, save lot of materials, reduce production costs.
(4) ripple radiating fin and heat-transfer pipe are integrated, without welding, also without pickling industry, free from environmental pollution again when having simplified manufacturing process; The fillet ripplet simultaneously caving on W shape ripple crest and trough is equivalent to reinforcing rib structure, and the vibration resistance of heat transfer element is strengthened, and can because vibration is violent, not cause radiating fin and heat-transfer pipe to produce and depart from.
Concrete structure of the present invention is provided by accompanying drawing 1,2,3.
