Pulling the hand-pull plate to operate the clamping column can quickly install and disassemble the mounting bracket.

[0015] 2. In the anti-scaling plate-fin heat exchanger, the liquid enters the interior of the head through the flow pipe fixed on one side of the head. When the liquid enters the interior of the head, it is filtered through the filter plate three, the filter plate two and the filter plate one in sequence to filter out the impurities in the liquid. The rubber pads connected to the two sides of the filter plate two can increase the sealing performance to prevent the liquid from leaking from both sides and being unable to be filtered. After the liquid passes through the three filter plates, it can prevent the impurities in the liquid from remaining in the heat exchanger to form dirt. The liquid is filtered by the filter plate one, the filter plate two and the filter plate three to remove the impurities, thereby achieving the effect of preventing scaling inside the heat exchanger.

[0022] The utility model embodiment provides an anti-scaling plate-fin heat exchanger.

[0023] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 A scale-proof plate-fin heat exchanger comprises a heat exchanger body 1, both sides of the heat exchanger body 1 are fixedly connected with a head 2, the front and rear ends of the head 2 are provided with movable grooves 3, the inside of the movable groove 3 is slidably connected with a connecting plate 4, one side of the connecting plate 4 is fixedly connected with a connecting rod 5, the connecting rod 5 is slidably connected to the inside of the head 2, the outside of the connecting rod 5 is sleeved with a spring 6, one end of the spring 6 is fixedly connected to one side of the connecting plate 4, the other end of the spring 6 is fixedly connected to the inner wall of one side of the movable groove 3, one end of the connecting rod 5 is fixedly connected with a hand-pull plate 7, and the other side of the connecting plate 4 is fixedly connected with a plurality of clamping columns 8, a placement groove 9 is provided on the head 2, the inner wall of the placement groove 9 is slidably connected with a mounting bracket 10, a plurality of clamping grooves 11 are provided on both sides of the mounting bracket 10, and the outside of the clamping column 8 is slidably connected to the inside of the clamping groove 11.

[0024] Working principle: when it is necessary to disassemble the filter plate 1 13, the filter plate 2 14 and the filter plate 3 15 for cleaning, firstly, it is necessary to pull the hand-pull plate 7 outwards. When the hand-pull plate 7 is pulled outwards, the connecting rod 5 fixedly connected to one side of the hand-pull plate 7 is driven to move outwards. When the hand-pull plate 7 drives the connecting rod 5 to move outwards, the connecting plate 4 fixedly connected to one end of the connecting rod 5 moves with the movement of the connecting rod 5. One end of the spring 6 sleeved on the outside of the connecting rod 5 is fixedly connected to the inner wall of one side of the movable groove 3. When the connecting rod 5 drives the connecting plate 4 to move outwards, the connecting plate 4 squeezes the spring 6. The spring 6 is compressed by the squeezing force.

[0025] When the connecting rod 5 drives the connecting plate 4 to move outward, the spring 6 fixedly connected to one side of the connecting plate 4 moves outward along with the movement of the connecting plate 4. The spring 6 leaves the inside of the card slot 11 along with the movement of the connecting plate 4. When the connecting plate 4 leaves the inside of the card slot 11, the handle 12 is pulled upward. When the handle 12 moves upward, the mounting bracket 10 fixedly connected to the handle 12 moves upward along with the movement of the handle 12.

[0026] When the mounting bracket 10 is completely out of the placement slot 9, release the hand-pull plate 7. At this time, the pressure applied to the spring 6 disappears. Because the spring 6 is elastic, the spring 6 will rebound when the squeezing force disappears. When the spring 6 rebounds, it pushes the connecting plate 4 toward the middle. When the connecting plate 4 moves toward the middle, it drives the column 8 fixedly connected to one side of the connecting plate 4 to reset. At the same time, when the connecting plate 4 moves toward the middle, it drives the connecting rod 5 fixedly connected to the other side of the connecting plate 4 to move toward the middle. When the connecting rod 5 moves toward the middle, it drives the hand-pull plate 7 fixedly connected to one side of the connecting rod 5 to reset.

[0027] When the mounting bracket 10 leaves the interior of the placement slot 9, the filter plates 1 13, 14 and 15 are pushed so that the filter plates 1 13, 14 and 15 can slide out from one side of the mounting bracket 10, thereby cleaning the filter plates 13, 14 and 15.

[0028] After the filter plate 1 13 , the filter plate 2 14 and the filter plate 3 15 are cleaned, the positioning column 17 is aligned with the positioning groove 18 . The positioning column 17 corresponds to the positioning groove 18 . After the positioning column 17 is aligned with the positioning groove 18 , the filter plate 1 13 , the filter plate 2 14 or the filter plate 3 15 is pushed. The positioning column 17 can be pushed into the inside of the positioning groove 18 , thereby driving the filter plate 1 13 , the filter plate 2 14 and the filter plate 3 15 to enter the inside of the mounting bracket 10 .

[0029] When filter plate 1 13, filter plate 2 14 and filter plate 3 15 are all inserted into the interior of the mounting bracket 10, the mounting bracket 10 is inserted into the placement groove 9. At this time, the hand-pull plate 7 is pulled outward. When the hand-pull plate 7 moves outward, it drives the connecting rod 5 fixedly connected to the hand-pull plate 7 to move outward. When the connecting rod 5 moves outward, the connecting plate 4 fixedly connected to one end of the connecting rod 5 moves outward with the movement of the connecting rod 5. At this time, the spring 6 mounted on the outside of the connecting rod 5 is squeezed with the movement of the connecting plate 4, and the spring 6 is compressed when subjected to the squeezing force.

[0030] When the connecting plate 4 moves outward, the card column 8 fixedly connected to one side of the connecting plate 4 moves outward with the movement of the connecting plate 4. When the card column 8 completely leaves the placement groove 9, the mounting bracket 10 can be completely inserted into the placement groove 9. When the mounting bracket 10 completely enters the placement groove 9, the hand-pull plate 7 is released. After the hand-pull plate 7 is released, the force applied to the spring 6 will disappear. At this time, the spring 6 rebounds and pushes the connecting plate 4 toward the middle. When the connecting plate 4 moves toward the middle, the card column 8 fixedly connected to one side of the connecting plate 4 will move with the movement of the connecting plate 4. When the connecting plate 4 moves toward the middle, the card column 8 will be inserted into the card groove 11 provided on the mounting bracket 10. The card column 8 corresponds to the card groove 11. After the card column 8 is inserted into the card groove 11, the mounting bracket 10 can be fixed.

[0031] Please refer again Figure 1 , Figure 2 , Figure 3 and Figure 4A handle 12 is fixedly connected to the top of the mounting bracket 10, a filter plate 13 is slidably connected to the inside of the mounting bracket 10, a filter plate 2 14 is slidably connected to the inside of the mounting bracket 10, a filter plate 3 15 is slidably connected to the inside of the mounting bracket 10, rubber pads 16 are fixedly connected to both sides of the filter plate 2 14, positioning columns 17 are fixedly connected to the top and bottom of the filter plates 13, 14 and 15, a plurality of positioning grooves 18 are opened inside the mounting bracket 10, a flow pipe 19 is fixedly connected to one side of the head 2, and the positioning column 17 is slidably connected to the inner wall of the positioning groove 18.

[0032] Working principle: The liquid enters the interior of the head 2 through the flow pipe 19 fixed on one side of the head 2. When the liquid enters the interior of the head 2, it is filtered through the filter plate 3 15, the filter plate 2 14 and the filter plate 1 13 in sequence to filter out the impurities in the liquid. The rubber pads 16 connected to the two sides of the filter plate 2 14 can increase the sealing performance to prevent the liquid from leaking from both sides and being unable to be filtered. After the liquid passes through the three filter plates, it can prevent the impurities in the liquid from remaining in the heat exchanger to form dirt.
