Please refer to fig. 1 to fig. 3, which illustrate a specific embodiment of a heat exchange device of the present invention.
Please refer to fig. 1 to 8 for a heat exchange device according to an embodiment of the present invention.
As described with reference to fig. 1 to 8, the present embodiment provides a heat exchange device, including: an outer cylinder 10; the guide cylinder 20 is longitudinally suspended in the outer cylinder 10 and forms a preset distance with two transverse end surfaces of the outer cylinder 10, and a longitudinal axis 200 of the guide cylinder 20 is parallel to or overlapped with a longitudinal axis 100 of the outer cylinder 10. In the embodiment of fig. 1, the longitudinal axis 200 of the guide shell 20 overlaps the longitudinal axis 100 of the outer shell 10. When the longitudinal axis 200 of the guide cylinder 20 is parallel to and does not overlap with the longitudinal axis 100 of the outer cylinder 10, the guide cylinder 20 is disposed at a position offset from the central axis (i.e., the longitudinal axis 100) of the outer cylinder 10, which is not shown in the drawings. The outer cylinder 10 is provided with a refrigerant inlet 101 for conveying a heat exchange medium therein and a refrigerant outlet 102 for discharging the heat exchange medium; the heat exchange device further comprises a coil 30 surrounding the outer wall of the guide cylinder 20 and forming a preset interval with the outer side of the guide cylinder 20 and the inner side of the outer cylinder 10 (the coil 30 is generally spirally wound on the outer side wall of the guide cylinder 20), wherein the flowing medium inlet end 301 and the flowing medium outlet end 302 of the coil 30 respectively extend out from two transverse end surfaces of the outer cylinder 10.
The coolant import that the heat transfer device urceolus 10 of this embodiment was seted up carries heat transfer medium in to urceolus 10, because the effect of draft tube 20, make heat transfer medium flow through the region between the coil pipe that encircles the draft tube 20 outer wall and the draft tube 20 outside, and the region between coil pipe 30 and the urceolus 10 inboard, discharge through the coolant export that urceolus 10 was seted up, and heat transfer medium flows through and constitutes to predetermine spaced region between the coil pipe that encircles the draft tube 20 outer wall and the draft tube 20 outside, and when constituting to predetermine spaced region between coil pipe 30 and the urceolus 10 inboard, can effectively carry out the heat transfer to the medium that flows in the coil pipe 30, and the heat exchange efficiency is improved. Therefore, the problem that the heat exchange efficiency of the heat exchanger in the prior art is low is solved. The guide shell 20 is suspended in the outer cylinder 10 to form a predetermined distance from the two lateral end surfaces of the outer cylinder 10, so that the guide shell 20 can avoid the pipe holes 301 'and 302' provided on the two lateral end surfaces of the outer cylinder 10 and used for extending the flowing medium inlet end 301 and the flowing medium outlet end 302 of the coil 30 respectively.
