Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to a smart energy-saving regional heat balance heat exchange device. Background Technology

[0002] A heat exchanger is an energy-saving device that enables heat transfer between two or more fluids at different temperatures. It transfers heat from a higher-temperature fluid to a lower-temperature fluid, allowing the fluid temperature to reach the specified parameters of the process to meet the requirements of the process conditions. It is also one of the main devices for improving energy efficiency.

[0003] A search of Chinese patent publication number CN214792701U reveals a heat exchange device.

[0004] The above technical solution includes a first heat exchange unit, a second heat exchange unit, and a third plate located between them. The first heat exchange unit has a first heat exchange channel and a second heat exchange channel. The first heat exchange channel is for refrigerant flow, and its flow area is smaller than that of the second heat exchange channel. The second heat exchange unit has a third heat exchange channel and a fourth heat exchange channel. The first heat exchange channel and the third heat exchange channel are directly or indirectly connected. The refrigerant flowing through the third heat exchange channel expands and then flows through the fourth heat exchange channel. The heat exchange device of this application integrates the first heat exchange unit and the second heat exchange unit to reduce the piping of the heat exchange device. Furthermore, the refrigerant flows through the first heat exchange channel with a smaller flow area, increasing the refrigerant flow rate, while the heat exchange fluid flows through the second heat exchange channel with a larger flow area, reducing the pressure drop of the heat exchange fluid, thereby meeting the pressure drop requirements of different heat exchange fluids in the first and second heat exchange channels.

[0005] However, while the above-mentioned solution can achieve the full heat exchange requirement, it cannot meet the temporary need for rapid heat exchange. Only after the heat exchange is completed step by step can a heat source or cold source flow out. During heat exchange, dust or scale is easily generated on the heat exchange tubes, which affects the heat exchange efficiency and causes heat energy waste.

[0006] Therefore, we propose a smart, energy-saving regional heat balance heat exchange device. Utility Model Content

[0024] The invention will now be further described with reference to the accompanying drawings and specific embodiments:

[0025] Example 1

[0026] Please see Figures 1 to 2 Embodiment 1 describes a housing 10, which serves as a heat source container. A heat source inlet 11 connects to the top of the housing 10, allowing the heat source to enter. A second heat source outlet 14 connects to the bottom of the housing 10, allowing the heat source to exit. An isolation plate 22 is installed inside the housing 10, dividing it into an upper heat exchange chamber 23 and a lower heat exchange chamber 24. The structures within the upper and lower heat exchange chambers 23 and 24 are symmetrical. The second heat source outlet 14 connects to the lower heat exchange chamber 24. The upper heat exchange chamber 23 connects to a first heat source outlet 12 located on the side of the housing 10, through which the heat source exits during rapid heat exchange. A first electric valve 13 is installed on the first heat source outlet 12, which remains normally closed during heat exchange. A second refrigerant inlet 17 is located on the other side of the housing 10, through which refrigerant enters. The second refrigerant inlet 17 connects to a first refrigerant pipe 20 located inside the housing 10, through which the first refrigerant pipe 20 exchanges heat with the heat source. The other end of the refrigerant pipe 20 is provided with a first refrigerant outlet 16. The first refrigerant pipe 20 is located in the upper heat exchange chamber 23, and the lower heat exchange chamber 24 is provided with a second refrigerant pipe 21. The second refrigerant pipe 21 also exchanges heat with the heat source. One end of the second refrigerant pipe 21 is connected to a second refrigerant inlet 17, and the other end of the second refrigerant pipe 21 is connected to a second refrigerant outlet 18. The second refrigerant inlet 17 and the second refrigerant outlet 18 are used for complete heat exchange. The upper heat exchange chamber 23 and the lower heat exchange chamber 24 are connected by a connecting pipe. A solenoid valve 26 is provided on the connecting pipe. The solenoid valve 26 controls the connection between the upper heat exchange chamber 23 and the lower heat exchange chamber 24 and also controls rapid heat exchange. Both ends of the first refrigerant pipe 20 and the second refrigerant pipe 21 are provided with second electric valves 19. The first refrigerant pipe 20 and the second refrigerant pipe 21 are fixed by S-shaped distributed turbulence plates 28. The second electric valves 19 are used to cooperate with heat exchange, and the turbulence plates 28 ensure sufficient contact of the heat medium.

[0027] In this embodiment, a heat source is injected from the heat source inlet 11 and enters the housing 10. Under the control of the turbulence plate 28, the heat source flows in an S-shape into the connecting pipe and then into the lower heat exchange chamber 24. The refrigerant in the lower heat exchange chamber 24 absorbs heat and cools the heat source on the side of the first refrigerant pipe 20 near the connecting pipe. Then, the heat source in the lower heat exchange chamber 24 flows out from the second heat source outlet 14 after passing through the S-shaped flow direction. When the refrigerant needs to be heated quickly, the solenoid valve 26 is closed and the first electric valve 13 is opened, and the heat source flows out from the first heat source outlet 12.

[0028] Example 2

[0029] Please see Figure 1 and Figure 3 Embodiment 2 describes a casing 10 with an insulation cover 27 installed on the side near the first heat source outlet 12. The insulation cover 27 reduces heat loss. A cleaning component 30 extending into the casing 10 is installed inside the insulation cover 27. Two cleaning components 30 are symmetrically distributed along the partition plate 22, respectively cleaning the upper heat exchange chamber 23 and the lower heat exchange chamber 24. Each cleaning component 30 includes a slide rail 35, with a slider 39 slidably connected within the slide rail 35. The slider 39 slides within the slide rail 35, and a cleaning rack 36 is fixedly connected to the upper end of the slider 39. The cleaning rack 36 is sleeved around the first refrigerant pipe 20. A cleaning brush 38 is provided to clean the outer surfaces of the first refrigerant pipe 20 and the second refrigerant pipe 21. A vibrator 37 is fixedly connected to one side of the cleaning rack 36. The vibrator 37 strengthens the contact strength. A lead screw 34 is rotatably connected inside the slide rail 35. The lead screw 34 is threadedly connected to the slider 39. One end of the lead screw 34 is fixedly connected to the transmission rod 33 extending out of the housing 10. The transmission rod 33 is fixedly connected to the output end of the motor 31. The motor 31 drives the cleaning rack 36 to move. A sealing gasket 32 ​​is also provided on the transmission rod 33 to rotate and seal with the housing 10. The sealing gasket 32 ​​is provided to prevent leakage.

[0030] In this embodiment, the motor 31 is started, which drives the transmission rod 33 to rotate. The rotation of the transmission rod 33 drives the lead screw 34 to rotate. The rotation of the lead screw 34 drives the slider 39 to slide in the slide rail 35. The sliding band of the slide rail 35 cleans one end of the first refrigerant pipe 20. The vibrator 37 is started, which drives the cleaning brush 38 to rotate. The cleaning brush 38 contacts the first refrigerant pipe 20 and sweeps off the scale and dust.
