[0029] Liquid is discharged through the No. 1 port 5 and liquid is input through the No. 2 port 6, so that the cooling liquid always flows in the reverse direction, thereby improving the spiral heat dissipation effect.

[0030] Among them, a side port 9 is opened on the outer side of the inner tube core 2, and the side port 9 is connected to the discharge port of the No. 2 spiral flow channel 15. The No. 1 hole 8 and the No. 2 hole 13 are eccentrically arranged on the end face of the inner tube core, and the No. 1 hole 8 and the No. 2 hole 13 are centrally symmetrically distributed in space.

[0031] By eccentrically and centrally symmetrically distributing the No. 1 hole 8 and the No. 2 hole 13, it is ensured that when the partition plate 71 is at a designated position, the No. 1 hole 8 and the No. 2 hole 13 are separated on the left and right sides to avoid interference and realize the separation and flow of the two fluids.

[0032] The distribution assembly 7 includes a partition 71, a baffle 72, a connecting column 73, a gear 74 and a connecting tube 75.

[0033] On the one hand, the distribution component 7 realizes separated circulation when it is stationary to separate the No. 1 hole 8 and the No. 2 hole 13, and quickly realizes the conduction of the two sets of flow channels when rotating, so as to avoid repeated operation of the two flow channels respectively during descaling and drying, and stirs the solution in the inner cylinder core 2 when rotating, and releases the descaling agent when the control valve 78 is opened to achieve rapid mixing.

[0034] Among them, the power component 11 includes a motor 111, a rotating shaft 112, a gear 2 113, blades 114 and an air supply tube 115. The motor 111 is fixed to one end of the inner tube core 2 and drives the fixedly connected rotating shaft 112 to rotate. The gear 2 113 is fixedly sleeved on the rotating shaft 112 and meshed with the gear 1 74.

[0036] Among them, the impact assembly 10 includes an impact column 101, an impact ring 102 and a spring 103. One end of the impact column 101 is movably sleeved in the inner tube core 2 and extends to the inside of the inner tube core 2. The other end of the impact column 101 passes through the No. 2 spiral plate 4 and extends between the No. 1 spiral plate 3 and the No. 2 spiral plate 4. The impact ring 102 is fixedly sleeved on the outer surface of the impact column 101. The spring 103 is fixedly connected between the impact ring 102 and the inner tube core 2. The partition 71 rotates and intermittently pushes the impact assembly 10 to move. Both ends of the impact column 101 have arc edges.

[0037] The impact assembly 10 is used for impact vibration to improve the dirt separation effect. The outer end of the impact column 101 impacts the first spiral plate 3, the impact ring 102 is used to hit the second spiral plate 4, and the spring 103 is used for elastic reset.

[0038] Among them, the feeding assembly 12 includes a second motor 121 and a spiral feeding mechanism 122. The second motor 121 is fixedly installed on the outer end of the inner cylinder core 2 and is located on the side close to the connecting pipe 75. The second motor 121 drives the spiral feeding mechanism 122 to rotate. The discharge end of the spiral feeding mechanism 122 is fixed at one end of the inner cylinder core 2 and is connected to the connecting pipe 75.

[0039] The feeding assembly 12 is used for spirally inputting the descaling agent, and cooperates with the storage chamber 76 and the control valve 78 to allow the descaling agent to flow into the mixing chamber from the side of the selected partition 71.

[0040] Embodiment 1: When in use, the fluid to be cooled is input along the No. 2 port 6 corresponding to the No. 2 spiral flow channel 15, and the hot fluid is input along the No. 1 hole 8 on the inner cylinder core 2. The hot fluid is blocked by the partition 71 in the inner cylinder core 2 and input upward into the No. 1 spiral flow channel 14 surrounded by the No. 1 spiral plate 3 and the No. 2 spiral plate 4, and flows in a spiral and is discharged toward the No. 1 port 5. The cold fluid enters the inner cylinder core 2 along the No. 2 spiral flow channel 15 and the side port 9 and is distributed on the other side of the partition 71. The cold fluid after absorbing heat passes through the No. 2 spiral flow channel 15 and the side port 9. When cleaning is needed, the No. 2 hole 13 is closed, and the cleaning liquid is input into the inner cylinder core 2 through the No. 1 hole 8, the motor 111 is started and the gear 1 74 is rotated through the gear 2 113, driving the connection column 73 to select, and the distribution component 7 is rotated, the partition 71 rotates in the inner cylinder core 2, and the feeding component 12 is started at the same time, so that the spiral feeding mechanism 122 delivers the descaling agent to the storage chamber 76 inside the partition 71, and the control valve 78 is kept open so that the descaling agent is removed. The scale remover is mixed into the inner cylinder core 2. As the partition 71 rotates, the input cleaning water and scale remover are stirred and mixed and respectively input into the No. 1 spiral flow channel 14 and the No. 2 spiral flow channel 15, and the accumulated dirt is melted. The gradually filled flushing water carries the melted dirt and is gradually discharged through the No. 1 port 5 and the No. 2 port 6 to complete the scale removal and cleaning. In the process of the partition 71 rotating and stirring in the inner cylinder core 2, the partition 71 uses the arc edge on the side to push the impact column 101 to move, and compresses the spring 103, and the impact column 101 is compressed. When the impact column 101 moves, it collides with the No. 1 spiral plate 3 and the impact ring 102 moves synchronously and hits the No. 2 spiral plate 4, so that the No. 1 spiral plate 3 and the No. 2 spiral plate 4 are both vibrated, and the dirt attached to the No. 1 spiral plate 3 and the No. 2 spiral plate 4 is further detached. As the partition 71 moves away, the spring 103 elastically resets and drives the impact column 101 to reset, reciprocatingly rotating and vibrating reciprocatingly. When the impact column 101 is in motion, a sealing ring (not shown in the figure) is provided between the No. 2 spiral plate 4 and the inner cylinder core 2 to avoid leakage.

[0041] First, through the rotatable distribution component 7, when the heat exchange between the cold and hot fluids is carried out, the partition 71 is kept stably positioned to realize the separation and circulation of the cold and hot fluids and complete the spiral heat exchange. When it is necessary to clean the dirt, the cleaning water is input through the No. 1 hole 8 by closing the No. 2 hole 13. During the input of the cleaning water, the cleaning water is respectively input into the No. 1 spiral flow channel 14 and the No. 2 spiral flow channel 15 by cooperating with the rotating partition 71, and the descaling agent is input into the partition 71 by using the feeding component 12, and the descaling agent is released during the rotation process. It is placed in the inner cylinder core 2, and coordinated with the rotation of the partition 71, the descaling agent is fully stirred and then quickly input into the No. 1 spiral flow channel 14 and the No. 2 spiral flow channel 15, so as to completely dissolve and clean the dirt inside the No. 1 spiral flow channel 14 and the No. 2 spiral flow channel 15. In fact, the two groups of flow channels are dissolved and cleaned synchronously, and the descaling agent released by cleaning is automatically mixed. For the spiral plate heat exchanger with double flow channels, fast and effective internal descaling treatment is achieved, and the fully dispersed descaling agent is used to dissolve the dirt clearly, and the actual descaling efficiency is high and the effect is good.

[0042] In addition, by utilizing the rotating partition 71, when realizing the mixed input of the flushing liquid and the descaling agent in the two-way flow channel, the rotating partition 71 is cooperated to intermittently push and impact the movably installed impact component 10, and during the impact process, the elasticity of the spring 103 is utilized, and the impact column 101 and the impact ring 102 that move quickly and reset are cooperated to synchronously impact and vibrate the first spiral plate 3 and the second spiral plate 4, thereby cooperating with the vibration effect to improve the separation effect of the attached dirt, and further improve the descaling effect.

[0043] Embodiment 2: After the heat exchanger is used up, the distribution assembly 7 is kept rotating. As the power assembly 11 drives the distribution assembly 7 to rotate, the internal blades 114 are driven to rotate in the air supply tube 115 and generate air volume. When the No. 2 hole 13 is closed, the air volume is input into the No. 1 hole 8. As the partition 71 rotates, the input air volume is distributed to the No. 1 spiral flow channel 14 and the No. 2 spiral flow channel 15. The air volume is input and output, completing the blowing and drying, and completing the dehumidification.

[0044] First, by utilizing the rotation of the distribution component 7 again, as the power component 11 drives the distribution component 7 to rotate, it also drives the internal blades 114 to rotate in the air supply tube 115 and generate air volume. When the No. 2 hole 13 is closed, the air volume is input into the No. 1 hole 8 through the pipeline. The rotation of the distribution component 7 is utilized again to guide the input airflow to the No. 1 spiral flow channel 14 and the No. 2 spiral flow channel 15 respectively, thereby completing the internal airflow purge and realizing the startup purge and drying after the fluid heat exchange is shut down, avoiding the corrosion of the metal spiral plate by the residual liquid in the heat exchanger, and improving the static protection effect.

[0045] The working principle and use process of the present invention are as follows: when in use, the fluid to be cooled is input along the No. 2 port 6 corresponding to the No. 2 spiral flow channel 15, and the hot fluid is input along the No. 1 hole 8 on the inner cylinder core 2. The hot fluid is blocked by the partition 71 in the inner cylinder core 2 and input upward into the No. 1 spiral flow channel 14 surrounded by the No. 1 spiral plate 3 and the No. 2 spiral plate 4, and flows in a spiral and is discharged toward the No. 1 port 5. The cold fluid enters the inner cylinder core 2 along the No. 2 spiral flow channel 15 and the side port 9 and is distributed on the other side of the partition 71. The cold fluid after absorbing heat is discharged through the No. 2 hole 13 to complete the spiral heat exchange. When cleaning is required, the No. 2 hole 13 is closed. The cleaning liquid is input into the inner cylinder core 2 through the No. 1 hole 8, the motor 111 is started and the gear 1 74 is rotated through the gear 2 113, driving the connection column 73 to select, and the distribution component 7 is rotated, the partition 71 rotates in the inner cylinder core 2, and the feeding component 12 is started at the same time, so that the spiral feeding mechanism 122 conveys the descaling agent to the storage chamber 76 inside the partition 71, and the control valve 78 is kept open, so that the descaling agent is mixed into the inner cylinder core 2. As the partition 71 rotates, the input cleaning water and descaling agent are stirred and mixed and respectively input into the No. 1 spiral flow channel 14 and the No. 2 spiral flow channel 15, and the accumulated attached water is dissolved. The dirt is gradually discharged from the first and second ports 5 and 6 by the flushing water that gradually fills up, carrying the dissolved dirt, to complete the descaling and cleaning. In the process of the partition 71 rotating and stirring in the inner cylinder core 2, the partition 71 uses the arc edge on the side to push the impact column 101 to move and compress the spring 103. When the impact column 101 moves, it collides with the first spiral plate 3 and the impact ring 102 moves synchronously and hits the second spiral plate 4, so that the first and second spiral plates 3 and 4 vibrate, and further the dirt attached to the first and second spiral plates 3 and 4 are detached. As the partition 71 moves away, the spring 103 elastically resets and drives the impact column 1 01 resets, reciprocates and vibrates reciprocatingly, and when the impact column 101 is in action, a sealing ring (not shown in the figure) is provided between the No. 2 spiral plate 4 and the inner tube core 2 to avoid leakage; when the heat exchanger is used up, the distribution component 7 is kept rotating, and as the power component 11 drives the distribution component 7 to rotate, the internal blades 114 are driven to rotate in the air supply tube 115 and generate air volume. When the No. 2 hole 13 is closed, the air volume is input into the No. 1 hole 8, and as the partition plate 71 rotates, the input air volume is distributed to the No. 1 spiral flow channel 14 and the No. 2 spiral flow channel 15, and the air volume is input and output to complete the blowing and drying, and complete the dehumidification.
