Wherein, the parallel way of the first snakelike flat tube 4 of snakelike flat tube 3 and second can be institute in Fig. 1-Fig. 2, Figure 11
The side for the connected mode, the now length direction of the first snakelike flat tube 4 of snakelike flat tube 3 and second laterally in parallel shown
It is connected.Certainly, the parallel way of the first snakelike flat tube 4 of snakelike flat tube 3 and second can also be longitudinal direction connection in parallel
Mode, now the first snakelike flat tube 3 be connected with the side of the width of the second snakelike flat tube 4.
Such as micro-channel heat exchanger of coiled heat exchanger 100 according to embodiments of the present invention, by making the first snakelike flat tube
3 and second snakelike flat tube 4 be arranged in parallel, compared with traditional coiled heat exchanger 100, flow reduction half, from
And flow resistance is significantly reduced, improve the performance of coiled heat exchanger 100.
According to some embodiments of the present invention, as shown in Figures 2 and 3, the first header 1 is open provided with first, the
Two headers 2 are open provided with second, and the first end of the first end of the first snakelike flat tube 3 and the second snakelike flat tube 4 is simultaneously
Row is inserted into the first opening, i.e., the first end of the first end of the first snakelike flat tube 3 and the second snakelike flat tube 4 and socket
Enter into the same opening of the first header 1, the of the second end of the first snakelike flat tube 3 and the second snakelike flat tube 4
Two ends are inserted into the second opening side by side, i.e., the second end of the second end of the first snakelike flat tube 3 and the second snakelike flat tube 4
In the same opening for being inserted into the second header 2 side by side.For example, in assembling, can be by the first snakelike flat tube 3
First end and the second snakelike flat tube 4 first end connection (such as weld) after be soldered to the of the first header 1 again
In one opening, and the second end of the first snakelike flat tube 3 and the second end of the second snakelike flat tube 4 connection (for example welding)
It is soldered to again afterwards in the second opening of the second header 2.

Description, rather than indicate or imply that the device or element of meaning must have specific orientation, with specific azimuth configuration
And operation, therefore be not considered as limiting the invention.
According to some embodiments of the present invention, the cross section of the first end of the first snakelike flat tube 3 and the second snakelike flat tube 4
First end cross section it is equal in magnitude and be rectangle, the cross section at the second end of the first snakelike flat tube 3 and the second snake
The cross section at the second end of shape flat tube 4 is equal in magnitude and is rectangle.For example, as shown in fig. 7, the first snakelike flat tube 3
First end and the second end in every one end length and the second snakelike flat tube 4 corresponding end equal length, and first
The width of the corresponding end of the width of every one end in the first end and the second end of snakelike flat tube 3 and the second snakelike flat tube 4
It is equal, during assembling, after the first end of the first snakelike flat tube 3 and the first end of the second snakelike flat tube 4 can be welded again
Welded with the first header 1, after the upper second end welding of the second end of the first snakelike flat tube 3 and the second snakelike flat tube 4
Welded again with the first header 1.Thus, due to the length direction of the first snakelike flat tube 4 of snakelike flat tube 3 and second
The junction at two ends is perfectly aligned and in the same plane, so that in the absence of the risk of weldering leakage.Now the first snakelike flat tube 3
