Description

Technical Field

[0001] The present invention relates to the technical field of plate heat exchangers, and specifically to an adaptive flow channel plate heat exchanger and its usage method. Background Art

[0002] A plate heat exchanger exchanges heat for water flow through plates. When the water flow rate is small, the contact area between the water flow and the plates becomes smaller, which easily causes a reduction in heat exchange efficiency. By varying the size of the flow channel space in the plates according to the water flow, the contact area between the water and the plates when the water flow rate is small can be increased.

[0003] The defects of existing plate heat exchangers are as follows: 1. The prior art KR101527894B1 discloses a plate heat exchanger, which does not have the function of adjusting the flow channels in the plates inside the plate heat exchanger according to the water flow rate. When the water flow rate is small, the water flow cannot fully contact and exchange heat with the flow channels of the plates, resulting in low heat exchange efficiency. Therefore, an adaptive flow channel plate heat exchanger that can adjust the space size of the flow channels inside the plates is needed to solve this problem.

[0004] 2. The prior art KR1020100126006A discloses a plate heat exchanger, which does not have a structure for cleaning impurities on the plates inside the plate heat exchanger. When impurities in the water adhere to the plates, it is easy to reduce the heat transfer efficiency between the water and the plates. Therefore, an adaptive flow channel plate heat exchanger that can clean the impurities adhering to the plates is needed to solve this problem.

[0005] 3. The prior art KR1020100117842A discloses a plate heat exchanger, which does not have a structure for adjusting the gap between the plates. When the water flow rate in the flow channels of the plates is small, the water flow cannot fill the space between adjacent plates, and the contact area between the water and the plates is small, resulting in low heat transfer efficiency. Therefore, an adaptive flow channel plate heat exchanger that can adjust the distance between the plates is needed to solve this problem.

[0006] 4. The prior art CN103703334B discloses a plate heat exchanger, which does not have a structure for conveniently replacing the plates. When the plates are damaged, the screws on the device need to be removed. When the number of screws is large, it is rather troublesome to disassemble and replace the plates. Therefore, an adaptive flow channel plate heat exchanger that can conveniently replace the plates is needed to solve this problem. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are: By setting the flow rate adjusting mechanism, the present invention can adaptively adjust the size of the flow space of the water flow. When the water flow rate in the flow channel groove is small, the spring squeezes the moving rod and the second frame body to the left, thereby reducing the size of the space in the flow channel groove, so that the water flow can fill the flow channel groove, increasing the contact area between the water flow and the inner wall of the flow channel groove to increase the heat exchange efficiency.

[0019] When the second frame body moves left and right, the first scraping rod and the second frame body clean the inner wall of the flow channel groove to prevent the heat exchange efficiency between the water flow and the heat exchange plate component from being reduced due to impurity coverage. At the same time, the second scraping rod cleans the inner wall of the second frame body to prevent the heat exchange efficiency between the water flow and the second frame body from becoming low due to impurity coverage.

[0020] When the water flow rate in the flow channel groove of the present invention is small, the hydraulic cylinder component can drive the rear end plate component to squeeze forward, thereby squeezing the rubber pad, reducing the space between the front and rear heat exchange plate components, further reducing the flow space of the water flow, and then increasing the contact area between the water flow and the heat exchange plate components, and increasing the heat exchange efficiency between the water flow and the heat exchange plate components.

[0033] The usage method of the self-adaptive flow channel plate heat exchanger is as follows: S1. When the water flow with a small flow rate enters the upper through hole 20 from the left upper pipe body 5 backward, the water flow then enters the flow channel groove 19 and then flows downward through the flow channel groove 19 into the lower through hole 20. S2. When the water flow rate in the flow channel groove 19 is small, the spring 27 squeezes the moving rod 22 and the second frame body 23 to the left, thereby reducing the space size in the flow channel groove 19, so that the water flow can fill the flow channel groove 19, increasing the contact area between the water flow and the inner wall of the flow channel groove 19 to increase the heat exchange efficiency. S3. When the water flow rate in the flow channel groove 19 is large, the water flow squeezes the moving rod 22 and the second frame body 23 to the right, thereby increasing the space size in the flow channel groove 19 and increasing the contact area between the water flow and the inner wall of the flow channel groove 19 to increase the heat exchange efficiency. S4. When the second frame body 23 moves left and right, the first scraping rod 24 and the second frame body 23 clean the inner wall of the flow channel groove 19 to prevent the heat exchange efficiency between the water flow and the heat exchange plate component 18 from decreasing due to impurity coverage. At the same time, the second scraping rod 25 cleans the inner wall of the second frame body 23 to prevent the heat exchange efficiency between the water flow and the second frame body 23 from becoming low due to impurity coverage. S5. By rotating the pressure rod 30 to move the pressure rod 30 away from the heat exchange plate component 18, it is convenient for people to replace the heat exchange plate component 18.

[0034] In S2, the following steps are also included: S21. At the same time, the hydraulic cylinder component 9 drives the rear end plate component 32 to squeeze forward, thereby squeezing the rubber pad 31, reducing the space size between the front and rear heat exchange plate components 18, further reducing the flow space of the water flow, and then increasing the contact area between the water flow and the heat exchange plate component 18, increasing the heat exchange efficiency between the water flow and the heat exchange plate component 18.

[0035] Working principle: Before using the adaptive flow channel plate heat exchanger, it should be checked whether there are any problems affecting its use. When the water flow with a small flow rate enters the upper through hole 20 from the left upper tube body 5 backward, the water flow then enters the inside of the flow channel groove 19 and then flows downward through the flow channel groove 19 into the lower through hole 20. When the water flow rate in the flow channel groove 19 is small, the spring 27 squeezes the moving rod 22 and the second frame 23 to the left, thereby reducing the space size in the flow channel groove 19, so that the water flow can fill the flow channel groove 19, increasing the contact area between the water flow and the inner wall of the flow channel groove 19 to increase the heat exchange efficiency. At the same time, the hydraulic cylinder component 9 drives the rear end plate component 32 to squeeze forward, thereby squeezing the rubber pad 31, reducing the space size between the front and rear heat exchange plate components 18, further reducing the flow space of the water flow, and then increasing the contact area between the water flow and the heat exchange plate components 18, increasing the heat exchange efficiency between the water flow and the heat exchange plate components 18. When the water flow rate in the flow channel groove 19 is large, the water flow squeezes the moving rod 22 and the second frame 23 to the right, thereby increasing the space size in the flow channel groove 19, increasing the contact area between the water flow and the inner wall of the flow channel groove 19 to increase the heat exchange efficiency. When the second frame 23 moves left and right, the first scraping rod 24 and the second frame 23 clean the inner wall of the flow channel groove 19 to prevent the heat exchange efficiency between the water flow and the heat exchange plate components 18 from being reduced due to impurity coverage. At the same time, the second scraping rod 25 cleans the inner wall of the second frame 23 to prevent the heat exchange efficiency between the water flow and the second frame 23 from becoming low. By rotating the pressure rod 30 to move the pressure rod 30 away from the heat exchange plate component 18, it is convenient for people to replace the heat exchange plate component 18.

9. The usage method of an adaptive flow channel plate heat exchanger according to any one of claims 1-8, characterized in that: The usage method of the adaptive flow channel plate heat exchanger is as follows: S1. When the water flow with a small flow rate enters the upper through hole one (20) from the left upper pipe body (5) backward, the water flow then enters the inside of the flow channel groove (19), and then flows downward through the flow channel groove (19) into the lower through hole one (20). S2. When the water flow rate in the flow channel groove (19) is small, the spring (27) squeezes the moving rod (22) and the frame two (23) to the left, thereby reducing the size of the space in the flow channel groove (19), so that the water flow can fill the flow channel groove (19), increasing the contact area between the water flow and the inner wall of the flow channel groove (19) to increase the heat exchange efficiency. S3. When the water flow rate in the flow channel groove (19) is large, the water flow squeezes the moving rod (22) and the frame two (23) to the right, thereby increasing the size of the space in the flow channel groove (19), increasing the contact area between the water flow and the inner wall of the flow channel groove (19) to increase the heat exchange efficiency. S4. When the frame two (23) moves left and right, the scraping rod one (24) and the frame two (23) clean the inner wall of the flow channel groove (19), avoiding the reduction of the heat exchange efficiency between the water flow and the heat exchange plate component (18) caused by impurity coverage. At the same time, the scraping rod two (25) cleans the inner wall of the frame two (23), avoiding the reduction of the heat exchange efficiency between the water flow and the frame two (23) caused by impurity coverage. S5. By rotating the pressing rod (30) to move the pressing rod (30) away from the heat exchange plate component (18), it is convenient for people to replace the heat exchange plate component (18).

10. The usage method of an adaptive flow channel plate heat exchanger according to claim 9, characterized in that: In the said S2, the following steps are further included: S21. At the same time, the hydraulic cylinder component (9) drives the rear end plate component (32) to be extruded forward, thereby extruding the rubber pad (31), reducing the size of the space between the front and rear heat exchange plate components (18), further reducing the flow space of the water flow, thereby increasing the contact area between the water flow and the heat exchange plate component (18), and increasing the heat exchange efficiency between the water flow and the heat exchange plate component (18).
