Description

Technical Field

[0001] This invention relates to the field of heat exchange control technology, specifically a cabinet-type heat exchange control device. Background Technology

[0002] Cabinet-type control heat exchangers are integrated heat exchange devices widely used in heating, air conditioning, and industrial processes to achieve heat transfer and temperature control.

[0003] Currently available cabinet-type heat exchangers, when used, carry away some metal rust and impurities as the cooling water passes through the heat exchanger's copper tubes and fins. These impurities need to be filtered before being removed from the heat exchanger to prevent them from affecting the heat exchange efficiency. However, after long-term use, the cooling water output from the heat exchanger still retains a certain temperature compared to room temperature water, which can cause the filter media in the filter to age over time. Therefore, a cabinet-type heat exchanger is needed to solve this problem. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a cabinet-type controlled heat exchange device, comprising a heat exchange device housing, a heat exchanger fixedly installed inside the heat exchange device housing, and a secondary side water pump fixedly installed on the heat exchanger. A secondary side filter is fixedly installed at the output end of the secondary side water pump, and the input end of the secondary side water pump is connected to the heat exchanger. An electric telescopic rod is fixedly installed on the outer wall of the secondary side filter, and a moving rod is fixedly connected to the output end of the electric telescopic rod. A first ball bearing is rotatably installed at one end of the moving rod. A corrugated pipe is fixedly connected to the inner wall of the secondary side filter. The corrugated pipe is configured as a telescopic flexible hose. A rotating frame is rotatably installed at one end of the corrugated pipe. A second annular groove is formed on the outer wall of the rotating frame, and the first ball bearing is slidably installed in the second annular groove. The inner wall of the rotating frame is connected to the inner wall of the corrugated pipe. A plurality of annularly arranged air outlets are formed on the rotating frame.

[0005] Preferably, the rotating frame is provided with a first annular groove, and the outer wall of the moving rod is fixedly connected to a first slider, which is slidably connected to the inner wall of the first annular groove.

[0006] Preferably, the inner wall of the secondary side filter is threaded with a filter housing, the inner wall of the filter housing is fixedly installed with a filter element, and the inner wall of the rotating frame is fixedly connected with a cleaning scraper for cleaning the outer wall of the filter housing, the cleaning scraper being configured as a hollow cylindrical shape.

[0007] Preferably, a second ball bearing is rotatably mounted on the outer wall of the rotating frame, and a spiral groove is formed on the inner wall of the secondary side filter, with the second ball bearing slidably mounted on the inner wall of the spiral groove.

[0008] Preferably, one end of the secondary side filter has a plurality of annularly distributed vent holes, which are in communication with the inner wall of the corrugated pipe.

[0009] Preferably, a fixed frame is fixedly installed at one end of the secondary side filter, the fixed frame is interconnected with the vent hole, and an air inlet pipe is fixedly connected to the outer wall of the fixed frame, the air inlet pipe is interconnected with the fixed frame.

[0010] Preferably, an installation base is fixedly installed on the inner wall of the heat exchanger housing, the heat exchanger is fixedly installed on the installation base, and a primary side water inlet pipe, a primary side water outlet pipe, a secondary side water inlet pipe and a secondary side water outlet pipe are fixedly installed on the heat exchanger. The primary side water inlet pipe, the primary side water outlet pipe, the secondary side water inlet pipe and the secondary side water outlet pipe are interconnected with the heat exchanger.

[0011] Preferably, a secondary side filter is fixedly installed on the secondary side outlet pipe, and a primary side filter is fixedly installed on the secondary side inlet pipe.

[0012] Preferably, a second water valve is fixedly installed on the secondary side outlet pipe, a first water valve is fixedly installed on the primary side filter, the secondary side water pump is fixedly installed on the secondary side outlet pipe, and a primary side water pump is fixedly installed on the secondary side inlet pipe.

[0013] Preferably, a cooling fan and a check valve are fixedly installed on the heat exchanger, and multiple check valves are provided.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, the rotation of the rotating frame causes the gas ejected from the air outlet to be in a circumferential rotational ejection state, changing from ejecting towards the filter housing in a single direction to ejecting upward in a rotating spiral, so that the cold air further acts on the outer wall of the filter housing for heat exchange, further increasing the heat dissipation effect on the filter housing and filter element.

[0015] 2. In this invention, when the rotating frame moves up and down to blow air and dissipate heat, the up and down movement of the rotating frame will move the cleaning scraper synchronously. The cleaning scraper will scrape up and down along the outer wall of the filter housing to prevent dust and impurities in the cold air from adhering to the surface of the filter housing and reducing the heat dissipation efficiency of the filter housing. Furthermore, when the rotating frame moves up and down while rotating, the rotating frame will move and rotate synchronously with the cleaning scraper. The rotation of the cleaning scraper can further clean the dust on the outer wall of the filter housing.

[0016] 3. In this invention, after the fixed frame is filled, the cold air enters the corrugated pipe through multiple annularly distributed vent holes, and is then transported upward through the corrugated pipe to the inner wall of the rotating frame. Finally, it is sprayed out inward through the annularly distributed vent holes on the inner wall of the rotating frame, thereby cooling the outer wall of the filter housing facing the vent holes.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: This example helps to solve the problem that the cooling water output after cooling by the heat exchanger still has a certain temperature compared to room temperature water, which can easily cause the filter media in the filter to age over time. Please refer to [link / reference]. Figure 1 - Figure 9 A cabinet-type controlled heat exchange device includes a heat exchange device housing 1, a heat exchanger 3 fixedly installed inside the heat exchange device housing 1, and a secondary side water pump 5 fixedly installed on the heat exchanger 3. A secondary side filter 6 is fixedly installed at the output end of the secondary side water pump 5, and the input end of the secondary side water pump 5 is connected to the heat exchanger 3. An electric telescopic rod 17 is fixedly installed on the outer wall of the secondary side filter 6. A moving rod 18 is fixedly connected to the output end of the electric telescopic rod 17. A first ball bearing 19 is rotatably installed at one end of the moving rod 18. A corrugated pipe 27 is fixedly connected to the inner wall of the secondary side filter 6. The corrugated pipe 27 is configured as a telescopic flexible hose. A rotating frame 21 is rotatably installed at one end of the corrugated pipe 27. A second annular groove 24 is opened on the outer wall of the rotating frame 21. The first ball bearing 19 is slidably installed in the second annular groove 24. The inner wall of the rotating frame 21 is connected to the inner wall of the corrugated pipe 27. A plurality of annularly arranged air outlets 33 are opened on the rotating frame 21. The rotating frame 21 has a first annular groove 22, and the outer wall of the moving rod 18 is fixedly connected to a first slider 20, which is slidably connected to the inner wall of the first annular groove 22.

[0021] The inner wall of the secondary filter 6 is threaded with a filter housing 31, and the inner wall of the filter housing 31 is fixedly installed with a filter element 32. The inner wall of the rotating frame 21 is fixedly connected with a cleaning scraper 23 for cleaning the outer wall of the filter housing 31. The cleaning scraper 23 is set as a hollow cylinder.

[0022] The secondary side filter 6 has multiple annularly distributed vent holes 28 at one end, and the vent holes 28 are connected to the inner wall of the bellows 27.

[0023] A fixed frame 29 is fixedly installed at one end of the secondary side filter 6. The fixed frame 29 is connected to the vent 28. An air inlet pipe 30 is fixedly connected to the outer wall of the fixed frame 29. The air inlet pipe 30 is connected to the fixed frame 29.

[0024] A mounting base 2 is fixedly installed on the inner wall of the heat exchanger housing 1. The heat exchanger 3 is fixedly installed on the mounting base 2. A primary side water inlet pipe 9, a primary side water outlet pipe 10, a secondary side water inlet pipe 13, and a secondary side water outlet pipe 7 are fixedly installed on the heat exchanger 3. The primary side water inlet pipe 9, the primary side water outlet pipe 10, the secondary side water inlet pipe 13, and the secondary side water outlet pipe 7 are interconnected with the heat exchanger 3. The primary side and the secondary side are physically completely isolated. They transfer heat through the heat dissipation copper pipes or heat dissipation copper plates of the heat exchanger 3. The media themselves do not mix. The secondary side pipeline: the water is pumped into the heat exchanger 3 through the secondary side water pump 5, leaving the heat to the heat dissipation copper pipes and heat dissipation copper plates of the heat exchanger 3. Then the temperature drops and the water is sent to the primary side filter 8 for filtration and then flows back to the heat-generating components of the chassis for direct heat exchange.

[0025] Primary side piping: Carrying externally connected low-temperature water, it is pumped into the other side of heat exchanger 3 by primary side water pump 4, where heat exchange absorbs the heat in the secondary side piping.

[0026] Both the primary and secondary side pipelines can be controlled to maintain their on / off states by controlling the opening and closing of the primary side water pump 4, the secondary side water pump 5, the second water valve 12, and the first water valve 11. After the water has been heated by the heat exchanger 3, it is drawn by the secondary side water pump 5 and pumped into the secondary side filter 6. The heated water entering the secondary side filter 6 is then transported into the filter element 32 to filter impurities. The filtered water is then transported away through the secondary side outlet pipe 7.

[0027] A secondary side filter 6 is fixedly installed on the secondary side outlet pipe 7, and a primary side filter 8 is fixedly installed on the secondary side inlet pipe 13.

[0028] A second water valve 12 is fixedly installed on the secondary side outlet pipe 7, a first water valve 11 is fixedly installed on the primary side filter 8, a secondary side water pump 5 is fixedly installed on the secondary side outlet pipe 7, and a primary side water pump 4 is fixedly installed on the secondary side inlet pipe 13.

[0029] A cooling fan 14 and a check valve 34 are fixedly installed on the heat exchanger 3. Multiple check valves 34 are provided.

[0030] In this embodiment: when using this cabinet-type heat exchange control device, the primary and secondary sides are physically completely isolated. They transfer heat through the heat dissipation copper pipes or plates of the heat exchanger 3, and the media themselves do not mix. Secondary side piping: The water is pumped into the heat exchanger 3 by the secondary side pump 5, leaving the heat to the heat dissipation copper pipes and plates of the heat exchanger 3. Then the temperature drops and the water is sent to the primary side filter 8 for filtration and then flows back to the heat-generating components of the chassis for direct heat exchange.

[0031] Primary side piping: Carrying externally connected low-temperature water, it is pumped into the other side of heat exchanger 3 by primary side water pump 4, where heat exchange absorbs the heat in the secondary side piping.

[0032] The on / off state of the pipelines on both the primary and secondary sides can be controlled by opening and closing the primary water pump 4, the secondary water pump 5, the second water valve 12, and the first water valve 11.

[0033] After the water has been heated by the heat exchanger 3, it is drawn by the secondary side water pump 5 and pumped into the secondary side filter 6. Impurities are filtered out in the filter element 32, and the filtered water is transported away through the secondary side outlet pipe 7.

[0034] During the filtration process of the secondary side filter 6, the high-pressure cold air pipe is connected to the air inlet pipe 30. The cold air sprayed from the air inlet pipe 30 enters the fixed frame 29. When the fixed frame 29 is full, the cold air enters the corrugated pipe 27 through multiple annularly distributed vent holes 28, and is then transported upward to the inner wall of the rotating frame 21 through the corrugated pipe 27. Finally, it is sprayed out centripetally through the annularly distributed air outlet holes 33 on the inner wall of the rotating frame 21, cooling the outer wall of the filter housing 31 towards which the air outlet holes 33 are facing.

[0035] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1-9 The outer wall of the rotating frame 21 is rotatably mounted with a second ball bearing 25, and the inner wall of the secondary side filter 6 is provided with a spiral groove 26, and the second ball bearing 25 is slidably mounted on the inner wall of the spiral groove 26.

[0036] In this embodiment: In order to enhance the cooling effect on the filter housing 31 and the filter element 32, the electric telescopic rod 17 can also be activated. After the electric telescopic rod 17 is activated, it moves the moving rod 18 at the output end upward. When the moving rod 18 moves upward, it moves the first slider 20 upward synchronously. Since the first slider 20 is located on the inner wall of the first annular groove 22, when the first slider 20 moves upward, it moves the rotating frame 21 upward as a whole. During the upward movement, the rotating frame 21 moves the second ball 25 along the inner wall of the spiral groove 26. Since the spiral groove 26 is set as a spiral groove, when the second ball 25 slides along the inner wall of the spiral groove 26, it causes the second ball 25 to rotate along the rotating frame 21 as a whole under force, so that the rotating frame 21 moves upward and rotates at the same time. When the rotating frame 21 rotates, it will rotate along the end of the bellows 27, but will not rotate the bellows 27 synchronously. The rotation of the rotating frame 21 causes the gas ejected from the air outlet 33 to be ejected in a circular rotation state, changing from being ejected in a single direction toward the filter housing 31 to being ejected in a rotating spiral upward, so that the cold air can further act on the outer wall of the filter housing 31 for heat exchange, further increasing the heat dissipation effect on the filter housing 31 and the filter element 32.

[0037] The second annular groove 24 is designed so that when the rotating frame 21 rotates, the moving rod 18 and the first ball 19 will slide along the inner wall of the second annular groove 24, thus avoiding jamming.

[0038] The corrugated pipe 27 is set as a retractable flexible hose. When the rotating frame 21 moves up and down, the corrugated pipe 27 can adapt to the expansion and contraction. The corrugated pipe 27 confines the cold air in a small space, which can ensure that the air pressure of the cold air is still relatively large when the cold air is transported over a long distance.

[0039] When the rotating frame 21 moves up and down to blow air and dissipate heat, the up and down movement of the rotating frame 21 will cause the cleaning scraper 23 to move synchronously. The cleaning scraper 23 will scrape up and down along the outer wall of the filter housing 31 to prevent dust and impurities in the cold air from adhering to the surface of the filter housing 31 and causing the heat dissipation efficiency of the filter housing 31 to decrease. Furthermore, as the rotating frame 21 moves up and down while rotating, the rotating frame 21 will move and rotate simultaneously with the cleaning scraper 23. The rotation of the cleaning scraper 23 can further clean the dust on the outer wall of the filter housing 31.
