Description

Technical Field

[0001] The invention belongs to the technical field of condensers and discloses a condenser and a system for a refrigerator. Background Art

[0002] A refrigerator is a device that converts a high-temperature fluid into a low-temperature fluid. The refrigerator mainly transfers the heat of one fluid to another fluid through the condenser inside it to achieve heat exchange. The condenser mainly converts the refrigerant with a higher temperature into the refrigerant with a lower temperature, and realizes heat recovery and utilization. However, in the actual use of the condenser, the temperature of the refrigerant generated by the refrigerator is not consistent due to the influence of the external environment, which makes the temperature of the refrigerant entering the condenser different. The refrigerant after heat exchange in the condenser needs to have a specified temperature. Therefore, it is necessary to control the operation mode of the condenser. For example, when the temperature of the refrigerant entering the condenser is high, it is necessary to increase the flow rate of the cooling water or reduce the temperature of the cooling water to ensure that the discharge refrigerant temperature is maintained at a constant value.

The upper side of the third rotating member 20 is fixedly connected with nine fixed rods 22 distributed in a ring. The upper end of the fixed rod 22 is provided with a scraper 23 that cooperates with the adjacent heat exchange tube 5. In the initial state, the angle between the inner scraper 23 and the adjacent heat exchange tube 5 is 60°, the angle between the middle scraper 23 and the adjacent heat exchange tube 5 is 36°, and the angle between the outer scraper 23 and the adjacent heat exchange tube 5 is 20°.

The right part of the upper side of the flow guide pipe 28 is located between the push plate 13 and the sealing disk 14. When the push plate 13 and the sealing disk 14 move upward or downward synchronously, the flow guide pipe 28 is always connected with the push plate 13 and the sealing disk 14.

[0032] The condenser is used to recover the heat in the high-temperature refrigerant. When the heat in the refrigerant needs to be recovered, the operator starts the control panel 101 through the remote control terminal. The control panel 101 introduces the refrigerant into the front water shell 4 through the second water inlet 401. The refrigerant passes through the heat exchange tube 5 and flows downward into the lower side of the shell 2, and continues to enter the rear water shell 3 and is discharged from the drain port 301. In the process of introducing the refrigerant into the front water shell 4, the control panel 101 introduces cooling water into the heat exchange cavity 202 through the first water inlet 201. The cooling water flows upward along the heat exchange cavity 202. In the process of the refrigerant contacting the heat exchange tube 5, the refrigerant passes through the heat exchange tube 5 and the heat exchange cavity 202. The cooling water in the cavity 202 undergoes heat exchange (the portion of the heat exchange tube 5 located on the lower side of the interception plate 7 participates in the heat exchange), the temperature of the refrigerant in the heat exchange tube 5 decreases, and the temperature of the cooling water in the heat exchange cavity 202 increases, thereby achieving the effect of waste heat recovery. The cooling water after the temperature has increased contacts with the lower surface of the interception plate 7 upward and is intercepted by it, and is finally discharged through the telescopic tube 8 and the water storage pipe 9. In the process of the cooling water flowing upward from the lower side of the heat exchange cavity 202, due to the obstruction of the guide plate 6, the flow path of the cooling water changes from vertically upward to bent upward, thereby increasing the degree of turbulence of the cooling water and improving the heat exchange efficiency. The flow rate sensor 402 in the second water inlet 401 always detects the flow rate of the refrigerant.

[0033] Since the temperature of the refrigerant entering the front water shell 4 is different, and some condensers need to discharge refrigerant of a specified temperature, too high or too low temperature will affect the operation of the condenser. Therefore, it is necessary to ensure that the temperature of the refrigerant discharged from the condenser is constant. The specific operation is as follows: in the process of the refrigerant entering the front water shell 4, the temperature of the refrigerant is transmitted to the heat-expanded liquid on the lower side of the insulation shell 11 through the heat-conducting rod 12. When the temperature in the front water shell 4 is too high, the volume of the heat-expanded liquid on the lower side of the insulation shell 11 increases, and the heat-expanded liquid on the lower side of the insulation shell 11 squeezes the sealing plate 14 to move upward. The sealing plate 14 squeezes the push plate 13 to move upward through the hydraulic oil on its upper side, and the content of the hydraulic oil between the push plate 13 and the sealing plate 14 does not change (because the fixed rod 22 on the left side contacts the inclined surface of the limit block 25, the limit block 25 cannot move to the right, the connecting plate 27 and the sliding rod 24 cannot move to the right, and the space between the push plate 13 and the sealing plate 11 in the insulation shell 11 The hydraulic oil between the plates 14 cannot enter the sealing shell 26 through the guide pipe 28. Therefore, in the process of the sealing plate 14 moving upward, the hydraulic oil content between the push plate 13 and the sealing plate 14 remains unchanged, and the distance between the push plate 13 and the sealing plate 14 remains unchanged). The push plate 13 moves upward so that the gas thereon is discharged through the through hole on the upper side of the insulation shell 11. The push plate 13 drives the intercepting plate 7 to move upward through the J-shaped rod 10, and the telescopic tube 8 is compressed. The upward movement of the intercepting plate 7 increases the area of ​​the heat exchange tube 5 participating in the heat exchange (specifically, the volume occupied by the cooling water in the heat exchange chamber 202 increases, and the cooling water stays in the heat exchange chamber 202 for a longer time), thereby improving the heat exchange efficiency between the waste liquid and the cooling water, and reducing the temperature of the discharged waste liquid. Similarly, when the temperature of the refrigerant in the water shell 4 before entering is low, the intercepting plate 7 moves downward so that the area of ​​the heat exchange tube 5 participating in the heat exchange is reduced, so that the temperature of the discharged waste liquid increases, and finally ensures that the temperature of the discharged refrigerant is at a constant value.

[0034] Some refrigerants contain easily adhered substances, which will adhere to the inner wall of the heat exchange tube 5. The adhesion of impurities will reduce the heat exchange area of ​​the inner wall of the heat exchange tube 5, thereby affecting the heat exchange efficiency of the heat exchange tube 5. If the impurities accumulate too much, it will also affect the flow rate of the refrigerant and make it difficult to clean it later. Therefore, it is necessary to regularly clean the impurities on the inner wall of the heat exchange tube 5. The specific operation is as follows: the control panel 101 starts the electric push rod 15, and the telescopic rod of the electric push rod 15 drives the first rotating member 16 to move upward, and the first rotating member 16 drives the two first limiting rods 17 to move upward, and the first limiting rod 17 slides upward along the adjacent first guide groove 203. The first limiting rod 17 is limited by the adjacent first guide groove 203 and rotates clockwise, and the two first limiting rods 17 drive the first rotating member 16 to rotate clockwise. The three fixed rods 22 and the scraper 23 thereon are driven to rotate clockwise. When the first rotating member 16 rotates 60° clockwise, the first limiting rod 17 enters the vertical portion of the adjacent first guide groove 203. The scraper 23 located above the first rotating member 16 is aligned with the three heat exchange tubes 5 on the inner side. During the upward movement of the first rotating member 16, the first rotating member 16 drives the second rotating member 18 to move upward. The second rotating member 18 drives the two second limiting rods 19 to move upward. The second limiting rods 19 slide upward along the adjacent second guide groove 204. The second limiting rods 19 are limited by the adjacent second guide groove 204 to rotate clockwise. The two second limiting rods 19 drive the second rotating member 18 to rotate clockwise. The second rotating member 18 drives the second limiting rods 19 to rotate clockwise. The five fixing rods 22 and the scraper 23 on the second rotating member 18 rotate clockwise. When the second rotating member 18 rotates 36° clockwise, the second limiting rod 19 enters the vertical portion of the adjacent second guide groove 204. The scraper 23 located above the second rotating member 18 is aligned with the five heat exchange tubes 5 on the middle side. During the upward movement of the second rotating member 18, the second rotating member 18 drives the third rotating member 20 to move upward. The third rotating member 20 drives the two third limiting rods 21 to move upward. The third limiting rod 21 slides upward along the adjacent third guide groove 205. The third limiting rod 21 is limited by the adjacent third guide groove 205 to rotate clockwise. The two third limiting rods 21 drive the third rotating member 20 to rotate clockwise. The third rotating member 20 drives the third limiting rods 21 on it. The nine fixed rods 22 and the scraper 23 rotate clockwise. When the third rotating member 20 rotates 20° clockwise, the third limiting rod 21 enters the vertical portion of the adjacent third guide groove 205. The scraper 23 located above the third rotating member 20 is aligned with the nine outer heat exchange tubes 5. At this time, all the scrapers 23 are aligned with the adjacent heat exchange tubes 5. As the telescopic rod of the electric push rod 15 continues to move upward, the scraper 23 contacts the inner wall of the adjacent heat exchange tube 5 and scrapes off the impurities adhered to the inner wall of the heat exchange tube 5. The inclined surface of the scraper ring of the scraper 23 guides the scraped impurities to the middle, avoiding the scraped impurities from contacting and adhering to the inner wall of the heat exchange tube 5 again, thereby improving the scraping efficiency of the impurities and avoiding the adhesion of the impurities affecting the heat exchange efficiency of the heat exchange tube 5.When the scraper 23 is located on the upper side of the inner wall of the adjacent heat exchange tube 5, the control panel 101 starts the telescopic rod of the electric push rod 15 to move downward, and all the scrapers 23 move downward. When the first limit rod 17 enters the inclined portion from the vertical portion of the adjacent first guide groove 203, the first limit rod 17 drives the three fixed rods 22 and the scraper 23 thereon to rotate counterclockwise through the first rotating member 16, and the three scrapers 23 on the inside and the three heat exchange tubes 5 on the inside are mutually misaligned. Similarly, the five scrapers 23 in the middle and the five heat exchange tubes 5 in the middle are mutually misaligned, and the nine scrapers 23 on the outside and the nine heat exchange tubes 5 on the outside are mutually misaligned. Finally, all the scrapers 23 are misaligned with the adjacent heat exchange tubes 5 to avoid the scrapers 23 being located in the positive direction of the adjacent heat exchange tube 5 and affecting the downward transportation of the refrigerant therein. When the electric push rod 15 is reset, the control panel 101 stops the electric push rod 15.

[0035] In the above process, since the fixing rod 22 and the scraper 23 are respectively inserted into the adjacent heat exchange tubes 5, this causes the cross-sectional area of ​​the heat exchange tube 5 to decrease. When the refrigerant flow rate is equal, the smaller the cross-sectional area of ​​the pipeline, the greater the refrigerant flow rate, and a too fast flow rate will cause the refrigerant to be discharged from the lower side of the heat exchange tube 5 before the heat exchange is completed, causing the temperature of the refrigerant to increase. Therefore, it is necessary to improve the heat exchange efficiency of the heat exchange tube 5 before the fixing rod 22 and the scraper 23 are inserted into the adjacent heat exchange tube 5. The specific operation is as follows: before the fixing rod 22 on the left is inserted into the adjacent heat exchange tube 5, it is necessary to rotate clockwise. The fixing rod 22 on the left rotates clockwise to squeeze the arc surface of the limit block 25. After the limit block 25 is squeezed, it drives the connecting plate 27 to move to the left through the sliding rod 24, and the external gas enters the connecting plate through the through hole on the upper right side of the sealing shell 26. The right side of 27 balances the pressure on the right side of the connecting plate 27 in the sealing shell 26, the elastic member on the right side of the connecting plate 27 is stretched, and the connecting plate 27 moves to the left to squeeze the hydraulic oil in the sealing shell 26 into the space between the push plate 13 and the sealing plate 14 in the insulation shell 11 through the guide tube 28. Since the position of the sealing plate 14 is only controlled by the heated and expanded liquid on its lower side, the sealing plate 14 does not move upward or downward, and the hydraulic oil added between the push plate 13 and the sealing plate 14 pushes the push plate 13 to move upward, and the push plate 13 drives the intercepting plate 7 to move upward through the J-shaped rod 10, thereby increasing the heat exchange area of ​​the heat exchange tube 5. By moving the intercepting plate 7 upward, the heat exchange area of ​​the heat exchange tube 5 is increased to compensate for the reduced heat exchange efficiency of the heat exchange tube 5 caused by the insertion of the fixing rod 22 and the scraper 23 into the heat exchange tube 5, thereby ensuring that the temperature of the refrigerant discharged from the lower side of the heat exchange tube 5 is at a constant value.

[0036] During the process of the left fixed rod 22 rotating counterclockwise to reset, the elastic part on the right side of the connecting plate 27 resets and drives the connecting plate 27 to move to the right. The connecting plate 27 drives the limit block 25 to move to the right and reset through the sliding rod 24. The connecting plate 27 moves to the right to draw the hydraulic oil between the push plate 13 and the sealing plate 14 into the sealing shell 26 through the guide pipe 28. The push plate 13 drives the intercepting plate 7 to move downward and reset through the J-shaped rod 10, and the hydraulic oil between the push plate 13 and the sealing plate 14 returns to the initial amount.

[0037] Embodiment 2: Based on embodiment 1, Figure 5 and Fig.10 As shown, it also includes a gathering mechanism, which is arranged on the left side of the rear water shell 3. The gathering mechanism is used to collect impurities in the rear water shell 3. The gathering mechanism includes an interception net 302. The interception net 302 is fixedly connected to the rear water shell 3 and is slidably connected to the telescopic rod of the electric push rod 15. In the process of the refrigerant passing through the rear water shell 3, the impurities carried in the refrigerant are intercepted by the interception net 302. The rear water shell 3 is fixedly connected to the guide shell 29. The upper part of the right side of the guide shell 29 is provided with a feed port 2901 connected to the rear water shell 3, and the lower part of the left side of the guide shell 29 is provided with a discharge port 2902. The guide shell 29 is provided with a separation component, and the separation component is used to separate the impurities and refrigerant in the guide shell 29.

[0038] like Fig.10 As shown, the separation component includes an extrusion plate 30, which is slidably connected to the right side of the guide shell 29. A through hole is provided on the upper side of the extrusion plate 30, and a screen and a one-way valve are provided in the through hole of the extrusion plate 30. The screen of the through hole of the extrusion plate 30 is located on the left side of the one-way valve. The refrigerant in the guide shell 29 will only flow to the right through the one-way valve of the through hole of the extrusion plate 30, and cannot flow to the left through the one-way valve of the through hole of the extrusion plate 30. The right side of the feed port 2901 and the interception net 302 are both higher than the left side, which are used to introduce impurities in the rear water shell 3 into the guide shell 29. A pull rod is fixedly connected to the left side of the extrusion plate 30 31. A limit plate 32 cooperating with the discharge port 2902 is slidably connected on the left side of the guide shell 29. In the initial state, the limit plate 32 is located on the right side of the discharge port 2902 to prevent impurities in the guide shell 29 from being discharged through the discharge port 2902. The limit plate 32 cooperates with the extrusion plate 30. The extrusion plate 30 moves to the left to extrude the impurities between the extrusion plate 30 and the limit plate 32. The limit plate 32 is slidably connected to the pull rod 31. A spring 33 is fixed between the limit plate 32 and the guide shell 29. The limit plate 32 is fixedly connected with a sleeve 34 slidably connected with the pull rod 31. The sleeve 34 is located on the outside of the pull rod 31.

[0039] In the process of the refrigerant passing through the rear water shell 3, the impurities carried in the refrigerant are intercepted by the interception net 302 and guided to enter the guide shell 29 through the feed port 2901. The impurities are located between the extrusion disk 30 and the limit disk 32. In the initial state, the limit disk 32 is located on the right side of the discharge port 2902 to prevent the impurities in the guide shell 29 from being discharged through the discharge port 2902. When the impurities in the guide shell 29 need to be cleaned, the operator pulls the pull rod 31 to the left, and the pull rod 31 drives the extrusion disk 30 to move to the left. Due to the elastic force of the spring 33, the limit disk 32 does not move to the left. In the process of the extrusion disk 30 moving to the left, the refrigerant between the extrusion disk 30 and the limit disk 32 enters the right side of the extrusion disk 30 through the through hole of the extrusion disk 30. Due to the interception effect of the screen in the through hole of the extrusion disk 30, the impurities between the extrusion disk 30 and the limit disk 32 cannot pass through the through hole of the extrusion disk 30, and the one-way transmission effect of the one-way valve in the through hole of the extrusion disk 30 makes the extrusion disk The refrigerant on the right side of the squeeze plate 30 cannot pass through the through hole of the squeeze plate 30 to flow to the left. Finally, only impurities exist between the squeeze plate 30 and the limit plate 32. As the squeeze plate 30 continues to move to the left, the squeeze plate 30 moves to the left through the impurities, and the spring 33 is compressed. When the impurities are located directly above the discharge port 2902, the impurities are discharged downward through the discharge port 2902. Then the operator pulls the sleeve 34 to the left, and the sleeve 34 drives the limit plate 32 to move to the left, and the impurities mixed between the limit plate 32 and the squeeze plate 30 fall downward. When the impurities between the limit plate 32 and the squeeze plate 30 are all discharged, the operator pushes the pull rod 31 to the right to reset, and the pull rod 31 drives the squeeze plate 30 to move to the right, and the refrigerant on the right side of the squeeze plate 30 returns to the rear water shell 3 through the feed port 2901. In summary, by intercepting impurities in the rear water shell 3, the cleanliness of the refrigerant in the rear water shell 3 is ensured, and at the same time, the intercepted impurities are cleaned regularly to achieve a continuous impurity removal process.
