[0025] As shown in the figure, a new type of high-efficiency tank heat exchanger includes a tank body 1. An inner cylinder 2 is installed at the middle position inside the tank body 1. A plurality of annular and sequentially sleeved medium guide plates 4 are installed in the cavity formed between the inner cylinder 2 and the tank body 1. Adjacent two medium guide plates 4 respectively form gaps with the top wall and the bottom wall of the tank body 1 in a staggered manner. That is, among two adjacent medium guide plates 4, the lower end of one medium guide plate 4 forms a gap with the bottom wall of the tank body 1, and the upper end of the other medium guide plate 4 forms a gap with the top wall of the tank body 1. The purpose is to enable the medium to fill the corresponding annular cavity each time, thereby facilitating the medium to stay in the tank body 1 for a longer time and improving the heat exchange efficiency.

[0026] Specifically, inside the tank body 1, a gap is formed between the outermost medium guide plate 4 and the bottom wall of the tank body 1, and a gap is formed between the innermost medium guide plate 4 and the top wall of the tank body 1. In this example, the purpose of such a setting is that a medium inlet pipe 6 is installed above the outside of the tank body 1, and the medium inlet pipe 6 communicates with the cavity formed between the tank body 1 and the outermost medium guide plate 4; a medium outlet pipe 5 is installed at the central position of the inner cylinder 2, the lower end of the medium outlet pipe 5 extends to the bottom position of the tank body 1, and the upper end of the medium outlet pipe 5 passes through the top wall of the tank body 1 and extends to the outside of the tank body 1. In this example, the number of medium guide plates 4 is two. As Figure 4 shown, after the medium enters the inside of the tank body 1 from the medium inlet pipe 6, it sequentially flows to the central position along the arrow direction shown in the figure, so that the medium stays in the tank body 1 for a longer time.

[0027] Specifically, a through hole 8 is opened at the lower end of the outer wall of the inner tube 2, and the medium between the inner tube 2 and the innermost medium guide plate 4 can enter the inner tube 2 through the through hole 8, so that the medium finally enters the inner tube 2 after flowing to the center position of the tank body 1, and then is discharged from the medium outlet pipe 5, forming a medium circulation process.

[0028] Specifically, it also includes a plurality of liquid coils 3 arranged inside the tank body 1. The medium guide plate 4 divides the inside of the tank body 1 into a plurality of different annular cavities. The plurality of liquid coils 3 are respectively distributed in different annular cavities, that is, the liquid coils 3 are in a spiral structure inside the tank body 1, which is mainly used for the liquid to stay in the tank body 1 for a long time, thereby generating efficient heat exchange with the medium.

[0029] Specifically, a liquid inlet pipe 10 is installed at the lower part of the outside of the tank body 1, and a liquid outlet pipe 9 is installed at the upper part of the outside of the tank body 1. The liquid inlet pipe 10 and the liquid outlet pipe 9 are respectively connected to the liquid coil 3 located inside the tank body 1, wherein the number of the liquid outlet pipe 9, the liquid inlet pipe 10, and the liquid coil 3 are eight, and the eight pipes can have a better heat exchange effect.

[0030] Specifically, a foot 7 is installed at the bottom of the tank body 1 .

[0031] Specifically, the tank body 1, the inner tube 2 and the medium guide plate 4 are coaxially arranged.

[0032] When this new type of high-efficiency tank heat exchanger is in use, the medium is fluorine, and the medium enters the tank body 1 from the medium inlet pipe 6. Since a plurality of cut-off guide plates are provided in the tank body 1, the medium needs to flow layer by layer in the tank body 1 to the middle position of the tank body 1, and finally flows out from the medium outlet pipe 5; at the same time, the liquid enters the liquid coil 3 in the tank body 1 from the liquid inlet pipe 10. During the flow, the liquid has sufficient heat exchange with the medium in the tank body 1, and finally is discharged from the liquid outlet pipe 9. Due to the structural design of the medium guide plate 4 in the tank body 1, the medium can stay in the tank body 1 for a longer time, and can have sufficient heat exchange with the liquid, thereby improving the overall heat exchange efficiency of the heat exchanger.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
