And heat exchanger heat-exchanging tube of the present invention adopts two kinds of caliber heat exchanger tubes of size, when the present invention makees condenser, for efficient low-resistance condenser, forward part is large footpath heat exchanger tube, and the forward part of windage and traditional condenser is suitable, but rear section is path heat exchanger tube, with respect to large-diameter pipes such as traditional condenser employings, the circulation area of its air increases, and the effective heat exchange area of fin increases, when having reduced the windage of heat exchanger, also strengthened heat transfer effect.
When the present invention makees evaporimeter, for efficient low-resistance evaporimeter, forward part is path heat exchanger tube, with respect to large-diameter pipes such as conventional evaporator employings, the circulation area of its air increases, and the effective heat exchange area of fin increases, when having reduced the windage of heat exchanger, also strengthened heat transfer effect.And Shi great footpath, rear section heat exchanger tube, the forward part of its windage and traditional condenser is suitable.
Therefore, the present invention, no matter do evaporimeter or condenser, not only can reduce air drag, reduces the power consumption of blower fan, has also promoted heat transfer effect, has promoted heat exchange efficiency, thereby has promoted the efficiency of complete machine.
3, reduce costs aspect: due to large-diameter pipes such as traditional heat exchangers employings, the consumptive material of heat exchanger tube is many, and cost is high, and the present invention has adopted the preparation method of part pipe with small pipe diameter, has reduced the consumptive material of heat exchanger tube, has reduced cost.
In sum, it is large that the present invention has effectively solved traditional heat exchangers resistance of the prior art, heat transfer effect is poor, heat exchanger consumptive material is many, the low-cost high-technology of efficiency is not enough, it adopts the heat exchanger tube combination of innovation, the preparation method of structure optimization and innovation, make a kind of high-efficient low resistant heat exchanger, reduced the resistance of heat exchanger, promoted heat transfer effect, also reduced the consumptive material of heat exchanger simultaneously, there is the expensive advantage such as low of efficiency, this high-efficient low resistant heat exchanger is compared with traditional heat exchangers, heat transfer effect is better, air drag is lower, when saving heat exchanger materials, promote the Energy Efficiency Ratio of air conditioner, the policy that meets national energy-saving and emission-reduction, there is higher economic and social benefit, be worth promoting.
