The specific working process of the invention is as follows:
when the heat exchanger works, a first heat exchange medium enters the rectangular cavity inside the bottom plate of the rectangular groove body 1 from the first medium inlet pipe 6, then enters the inside of the first wound hollow plate 2, enters the free end of the second wound hollow plate 5 through the free end of the first wound hollow plate 2, then enters the inside of the rectangular cavity again through the fixed end of the second wound hollow plate 5, so that the first heat transfer medium flows from the rectangular groove body 1 at the bottom layer to the rectangular groove body 1 at the top layer through the path of the rectangular cavity, the first wound hollow plate 2, the second wound hollow plate 5 and the rectangular cavity, and finally flows out from the first medium outlet pipe 9 on the rectangular groove body 1 at the top layer, meanwhile, the second heat exchange medium enters the inside of the rectangular groove body 1 at the top layer from the second medium inlet pipe 3, and then enters the inside of the rectangular groove body 1 at the next layer through the liquid inlet channel 10 at the tail end, and finally discharged from a second medium discharge pipe 12 on the rectangular tank body 1 at the bottom layer, thereby realizing the heat exchange between the two media; when a first heat exchange medium enters the first medium inlet pipe, the first wound hollow plate 2 and the second wound hollow plate 5 are enabled to be in a state of tending to be flattened by the medium entering the first wound hollow plate 2 and the second wound hollow plate 5, and when the flow of the first heat exchange medium entering the first medium inlet pipe 6 is controlled by the flow control device and the first heat exchange medium is enabled to be in a state of alternating large flow and small flow, at the moment, the first wound hollow plate 2 and the second wound hollow plate 5 are enabled to be in a state of alternating expansion and winding under the action of large flow impact and small flow rebound force of the first heat exchange medium, at the moment, the first wound hollow plate 2 and the second wound hollow plate 5 can swing back and forth in the rectangular body 1 to be in full contact with the second heat exchange medium at different positions, so that the heat exchange efficiency is better, and because the maximum diameters of the first winding hollow plate 2 and the second winding hollow plate 5 are not equal, the swing amplitudes of the first winding hollow plate 2 and the second winding hollow plate 5 are also different, thereby forming turbulent flow in the second heat transfer medium inside the rectangular tank body 1, enabling the second heat transfer medium at different positions inside the rectangular tank body 1 to have the opportunity of contacting with the first winding hollow plate 2 and the second winding hollow plate 5, further enabling the heat exchange efficiency of the first heat transfer medium inside the first winding hollow plate 2 and the second winding hollow plate 5 and the second heat transfer medium inside the rectangular tank body 1 to be higher, avoiding the second heat transfer medium far away from the first winding hollow plate 2 and the second winding hollow plate 5 from being incapable of contacting with the first winding hollow plate 2 and the second winding hollow plate 5, and enabling the energy of the second heat transfer medium to be fully utilized, energy waste is avoided; meanwhile, the first winding hollow pipe 2 and the second winding hollow pipe 5 increase the heat exchange path of the first heat exchange medium in the rectangular groove body 1, so that the contact time of the first winding hollow plate 2 and the second winding hollow plate 5 with the second heat exchange medium is prolonged, the heat exchange time is prolonged, the heat exchange is more sufficient, and the energy consumption is further reduced.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
