[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] A high-efficiency heat exchanger unit with a filtration mechanism, combined with Figure 1As shown, it includes a horizontal heat exchange cylinder 1, the interior of which is a hollow heat exchange chamber 2; a high-temperature medium inlet 3 and a low-temperature medium outlet 4 are arranged opposite to each other on the left and right sides of the heat exchange cylinder 1, and the high-temperature medium inlet 3 and the low-temperature medium outlet 4 are connected to the heat exchange chamber 2; a high-temperature medium outlet 6 and a low-temperature medium inlet 5 are arranged opposite to each other on the left and right sides of the top of the heat exchange cylinder 1.

[0019] The heat exchange chamber 2 is uniformly equipped with several horizontally arranged serpentine heat exchange tubes 7. The two ends of each serpentine heat exchange tube 7 are connected to the high-temperature medium outlet 6 and the low-temperature medium inlet 5 via a shaped transition tube 8, forming a complete heat exchange channel. The high-temperature medium outlet 6 and the high-temperature medium inlet 3 are located on the same side, and the low-temperature medium outlet 4 and the low-temperature medium inlet 5 are located on the same side, enabling convective heat exchange between the high-temperature and low-temperature media, thus improving heat exchange efficiency. Specifically, the serpentine heat exchange tubes 7 and the shaped transition tubes 8 are integrally formed, and their surfaces are etched with a raised dot matrix 81. The raised dot matrix 81 increases the specific surface area, disrupts the boundary layer of the medium flow, enhances turbulence, and further improves heat exchange efficiency.

[0020] A first filter mechanism 9 is sealed to the high-temperature medium inlet 3. The inlet of the first filter mechanism 9 is sealed to the high-temperature medium conveying pipeline 11. The first filter mechanism 9 is used to filter the high-temperature medium conveyed from the high-temperature medium conveying pipeline 11. Specifically, the first filter mechanism 9 includes a first housing 91. First flanges 92 are respectively provided at the inlet and outlet of the first housing 91. The first filter mechanism 9 is sealed to the high-temperature medium inlet 3 and the high-temperature medium conveying pipeline 11 through the first flanges 92. Inside the first housing 91, in the reverse direction of the medium flow, a silicon carbide perforated plate 96, a first coarse filter screen 93, a first adsorbent particle layer 94, and a first fine filter screen 95 are arranged sequentially. The silicon carbide perforated plate 96 prevents damage to the internal components of the first filter mechanism 9 from the thermal shock force of the hot fluid entering. The first coarse filter screen 93 intercepts larger particulate impurities. The first adsorbent particle layer 94 adsorbs small impurities and colloids in the medium. The first fine filter screen 95 further filters smaller particulate impurities. This combination of multiple filtration methods effectively purifies the medium and prevents impurities from entering the heat exchange chamber 2 and affecting the heat exchange effect. When it is necessary to replace the first filter mechanism 9 or to inspect and clean the first filter mechanism 9, the first filter mechanism 9 can be easily removed through the first flange 92.

[0021] A second filter mechanism 10 is sealed to the cryogenic medium inlet 5. The inlet of the second filter mechanism 10 is sealed to the cryogenic medium conveying pipeline 12. The second filter mechanism 10 is used to filter the cryogenic medium conveyed from the cryogenic medium conveying pipeline 12. Specifically, the second filter mechanism 10 includes a second housing 101. Second flanges 102 are respectively provided at the inlet and outlet of the second housing 101. The second filter mechanism 10 is sealed to the cryogenic medium inlet 5 and the cryogenic medium conveying pipeline 12 through the second flanges 102. Inside the second housing 101, in the reverse direction of the medium flow, a second coarse filter 103, a second adsorption particle layer 104, and a second fine filter 105 are arranged sequentially. The second coarse filter 103 is used to intercept larger particulate impurities; the second adsorption particle layer 104 can adsorb small impurities and colloids in the medium; and the second fine filter 105 is used to further filter smaller particulate impurities. The combination of multiple filtration methods can effectively purify the medium and prevent impurities from entering the serpentine heat exchange tube 7 and the irregularly shaped transition tube 8, thus affecting the heat exchange effect. When it is necessary to replace the second filter mechanism 10 or to inspect and clean the second filter mechanism 10, the second filter mechanism 10 can be easily removed through the second flange 102.

[0022] Pumps 13 are installed on the high-temperature medium conveying pipeline 11 and the low-temperature medium conveying pipeline 12 respectively. The controlled end of the pump 13 is connected to a PLC controller, and the PLC controller can realize the automatic adjustment of the medium flow rate.

[0023] Temperature sensors are installed on the high-temperature medium inlet 3, low-temperature medium outlet 4, low-temperature medium inlet 5, and high-temperature medium outlet 6 respectively. The output of the temperature sensors is connected to the input of the PLC controller to monitor the medium temperature in real time and ensure the heat exchange process is stable and efficient.

[0024] The working principle of this utility model is as follows:

[0025] (1) Media filtration process

[0026] The high-temperature medium enters the heat exchanger unit through the high-temperature medium inlet 3. First, it passes through the silicon carbide perforated plate 96 of the first filter mechanism 9; then, it passes through the first coarse filter 93 to intercept large particulate impurities; subsequently, it passes through the first adsorption particle layer 94 to adsorb small particles and harmful substances; finally, it passes through the first fine filter 95 to remove small particulate impurities, ensuring that the high-temperature medium entering the heat exchange chamber 2 is clean and free of impurities.

[0027] The low-temperature medium enters the heat exchanger unit through the low-temperature medium inlet 5, and passes through the second coarse filter 103, the second adsorption particle layer 104 and the second fine filter 105 of the second filtration mechanism 10 in sequence. After removing impurities, it enters the serpentine heat exchange tube 7 through the irregular transition tube 8.

[0028] (2) Heat exchange process

[0029] The filtered high-temperature and low-temperature media undergo convective heat exchange inside the insulation cylinder 1.

[0030] The high-temperature medium releases heat, while the low-temperature medium absorbs heat through the serpentine heat exchange tube 7 and the irregularly shaped transition tube 8, achieving efficient heat exchange.

[0031] The etched dot matrix 81 on the surface of the serpentine heat exchange tube 7 and the irregularly shaped transition tube 8 increases the specific surface area, disrupts the boundary layer of the medium flow, enhances the turbulence effect, and further improves the heat exchange efficiency.

[0032] (3) Media flow and control

[0033] High-temperature medium and low-temperature medium are sent into the heat exchanger unit through high-temperature medium conveying pipeline 11 and low-temperature medium conveying pipeline 12, respectively. The pump 13 installed on the pipeline is controlled by a PLC controller to realize the automatic adjustment of the medium flow rate.

[0034] Temperature sensors monitor the temperatures of high-temperature medium inlet 3, low-temperature medium outlet 4, low-temperature medium inlet 5, and high-temperature medium outlet 6 in real time, and feed the data back to the PLC controller to ensure a stable and efficient heat exchange process.

[0035] (4) The medium is discharged after heat exchange.

[0036] After heat exchange, the high-temperature medium is discharged through the high-temperature medium outlet 6, and the low-temperature medium is discharged through the low-temperature medium outlet 4, thus completing the entire heat exchange process.
