[0030] In the embodiment of the present disclosure, as shown in Figure 5 the outer wall of the flow guide column 9 and the inner wall of the inner cylinder 7 are provided with an annular cavity, and the flow guide plate 10 is an annular plate and is located in the annular cavity outside the flow guide column 9, the first medium entering the cavity inside the inner cylinder 7 will continue to flow upwards in the annular cavity outside the flow guide column 9, in this process, the first medium can only flow upwards through the staggered openings on the flow guide plate 10, so it can uniformly contact with the inner wall of the inner cylinder 7 and the flow guide plate 10, and when the second medium flows downwards, it will also affect the temperature of the inner cylinder 7 and the flow guide plate 10, so the first medium can continue to exchange heat when flowing upwards in the inner cylinder 7.
[0031] In the embodiment of the present disclosure, as shown in Figures 2-4As shown, the part of the first medium inlet pipe 3 located in the internal cavity of the heat exchange tank body 1 is a spiral pipe, and the spiral pipe is located in the spiral channel separated by the turbulence vane 8. In use, the first medium can be introduced into the heat exchanger through the first medium inlet pipe 3, and at this time, the first medium will flow towards the circular hole at the bottom of the inner cylinder 7 through the spiral pipe part of the first medium inlet pipe 3, and at the same time, the second medium is introduced into the cavity between the inner wall of the heat exchange tank body 1 and the outer wall of the inner cylinder 7 through the second medium inlet pipe 5, and then the second medium will flow downward in the channel separated by the turbulence vane 8. In this process, the second medium will be in contact with the spiral pipe part of the first medium inlet pipe 3, so as to exchange heat with the first medium in the spiral pipe of the first medium inlet pipe 3.
[0032] In the embodiment of the present disclosure, as shown in Figure 5 As shown, one side of the guide plate 10 is provided with an opening penetrating up and down, and the openings on the adjacent guide plates 10 up and down are staggered left and right. When the first medium flows upward in the inner cylinder 7, it can only flow upward through the staggered openings on the guide plate 10, so it can uniformly contact the inner wall of the inner cylinder 7 and the guide plate 10.
[0033] In the embodiment of the present disclosure, as shown in Figure 2 , Figure 3 and Figure 5 As shown, the top and bottom of the inner cylinder 7 are each provided with a circular hole, the bottom end of the first medium inlet pipe 3 is connected to the circular hole at the bottom of the inner cylinder 7, and the bottom end of the first medium outlet pipe 4 is connected to the circular hole at the top of the inner cylinder 7. In use, the first medium can be introduced into the heat exchanger through the first medium inlet pipe 3, and at this time, the first medium will flow towards the circular hole at the bottom of the inner cylinder 7 through the spiral pipe part of the first medium inlet pipe 3. Finally, the first medium that has completed heat exchange will flow outwards through the first medium outlet pipe 4.
[0034] In the embodiment of the present disclosure, as shown in Figure 2 , Figure 3 and Figure 6 As shown, the inner side of the turbulence vane 8 is tightly attached to the outer wall of the inner cylinder 7, and the outer side of the turbulence vane 8 is tightly attached to the inner wall of the heat exchange tank body 1. The inner side and the outer side of the turbulence vane 8 are each provided with a flange structure. After the flange structure is added to the turbulence vane 8, the outer flange of the turbulence vane 8 can be tightly attached to the inner wall of the heat exchange tank body 1 during assembly, so that the medium flows from top to bottom according to the flow channel of the turbulence vane 8, and the expected energy efficiency will not be affected by the damage to the outer side of the turbulence vane 8.
[0035] In the embodiment two, on the basis of the embodiment one, as shown in Figures 1 to 6As shown, the inner cylinder 7 is a copper shell, and the guide plates 10 are also copper plates. When the first medium flows upward in the inner cylinder 7, it can only flow upward through the staggered openings of the guide plates 10, and thus can uniformly contact the inner wall of the inner cylinder 7 and the guide plates 10. When the second medium flows downward, it also affects the temperature of the inner cylinder 7 and the guide plates 10. Therefore, the first medium can continue to exchange heat when flowing upward in the inner cylinder 7. The copper structure is more conducive to improving the heat exchange effect.
[0036] The working principle of the embodiment is as follows: when installed, the heat exchange tank body 1 can be supported and fixed on the ground through the base 2. Then, the conveying pipeline of the first medium needing heat exchange is connected with the first medium inlet pipe 3 and the first medium outlet pipe 4, and the conveying pipeline of the second medium needing heat exchange is connected with the second medium inlet pipe 5 and the second medium outlet pipe 6. When used, the first medium can be introduced into the heat exchanger through the first medium inlet pipe 3. At this time, the first medium flows toward the circular hole at the bottom of the inner cylinder 7 through the spiral pipe part of the first medium inlet pipe 3. Then, the second medium is introduced into the cavity between the inner wall of the heat exchange tank body 1 and the outer wall of the inner cylinder 7 through the second medium inlet pipe 5. Then, the second medium flows downward in the channel separated by the turbulence piece 8. In this process, the second medium contacts the spiral pipe part of the first medium inlet pipe 3, so that the heat exchange between the first medium in the spiral pipe of the first medium inlet pipe 3 and the second medium can be realized. The first medium introduced into the internal cavity of the inner cylinder 7 continues to flow upward in the annular cavity outside the guide column 9. In this process, the first medium can only flow upward through the staggered openings of the guide plates 10, and thus can uniformly contact the inner wall of the inner cylinder 7 and the guide plates 10. When the second medium flows downward, it also affects the temperature of the inner cylinder 7 and the guide plates 10. Therefore, the first medium can continue to exchange heat when flowing upward in the inner cylinder 7. Finally, the first medium after heat exchange flows outward through the first medium outlet pipe 4, and the second medium after heat exchange flows outward through the second medium outlet pipe 6.
