2With respect to linkage section flat tube P
12Reverse second angle.The scope of first angle and second angle can for roughly 45 to 135 the degree.According to technological requirement, the scope of first angle and second angle also can for roughly 0 to 180 the degree.
Next, can crooked linkage section flat tube P
12, make linkage section flat tube P
12Or linkage section flat tube P
12Pars intermedia be divided into roughly arc.As selection, can and make first section flat tube P after the step of the flat tube that predetermined length is provided
1With respect to linkage section flat tube P
12Reverse first angle and make second section flat tube P
2With respect to linkage section flat tube P
12Reverse before the step of second angle crooked linkage section flat tube P
12, make linkage section flat tube P
12Or linkage section flat tube P
12Pars intermedia be divided into roughly arc.Can pass through crooked linkage section flat tube P
12, make first section flat tube P
1With second section flat tube P
2Between angle be roughly 0 to 90 the degree.As shown in Figure 5, by linkage section flat tube P with respect to the roughly camber of flat tube assembly P
12T in the clockwise direction
1Reverse first section flat tube P
1And form the first wreath piece J
1, and with respect to linkage section flat tube P
12T in the clockwise direction
2Reverse second section flat tube P
2And form the second wreath piece J
2, thus, form flat tube assembly P.According to the dogleg section at the top of flat tube assembly P of the present invention by an arc flat pipe carry out twice clockwise distortion form.
In the heat exchanger that flat tube assembly P constitutes according to an embodiment of the invention, air along the direction shown in the arrow A from first section flat tube P
1With second section flat tube P
2Between the space that forms outside this space, blow.In addition, air also can be from first section flat tube P
1With second section flat tube P
2The top by first section flat tube P
1With second section flat tube P
2Between this space, lateral in the space that forms blow, promptly air is along blowing in the opposite direction with the side shown in the arrow A.In addition, air also can blow with any other suitable manner well known in the art.As shown in Figure 4, dotted arrow RL is illustrated in first section flat tube P
1In be in the flow direction of the cold-producing medium of leeward side, and solid arrow RW is illustrated in first section flat tube P
1In be in the flow direction of the cold-producing medium of windward side.
As shown in Figure 4, by the flat tube distortion mode at change heat exchanger top, two heat exchanger windward sides and leeward side are alternately about making.The cold-producing medium that dotted arrow RL represents is a leeward side at the left side heat exchanger, just becomes windward side to the right side heat exchanger; The cold-producing medium that solid arrow RW represents is a windward side at the left side heat exchanger, just becomes leeward side to the right side heat exchanger.Like this can balanced cold-producing medium and the heat transfer temperature difference of air, can improve the heat exchange efficiency of heat exchanger.
When heat exchanger according to the present invention when the evaporimeter, the temperature curve of air and cold-producing medium as shown in Figure 6, wherein dotted line is illustrated in first section flat tube P
1In be in the cold-producing medium of leeward side from header H
1Flow to header H
2Variations in temperature, and solid line is illustrated in first section flat tube P
1In be in the cold-producing medium of windward side from header H
1Flow to header H
2Variations in temperature, as can be seen from the figure, first section flat tube P
1' in be in the cold-producing medium of leeward side and at first section flat tube P
1' in be in windward side cold-producing medium along with from header H
1Flow to header H
2The temperature difference reduces gradually.That is, because left side heat exchanger leeward side cold-producing medium transfers windward side to the right side, left side heat exchanger windward side transfers leeward side to the right side, can balanced cold-producing medium in the temperature field of heat exchanger, assurance exports the identical degree of superheat, has improved the heat transfer efficiency of heat exchanger.
Evaporimeter can be used as according to this heat exchanger of the present invention, also condenser can be used as.The air intake mode of heat exchanger shown in Figure 5 is last air-out, and heat exchanger of the present invention is equally applicable to down the air-out mode of air-out and horizontal air-out.
