Description

Technical Field

[0001] This utility model relates to the field of air-water cooling equipment, and in particular to an air-water cooling device. Background Technology

[0002] High-voltage frequency converters are widely used in industrial production fields such as power, chemical, coal mining, metallurgy, petrochemical, cement, and steel. Although their operating efficiency is as high as 96% to 98%, the equipment power usually reaches the megawatt level, and a large amount of heat is still generated during normal operation. To ensure stable operation of the equipment, this heat must be dissipated in a timely and effective manner.

[0003] High-voltage frequency converter air-water cooling equipment (hereinafter referred to as "air-water cooling equipment") is a highly efficient and reliable heat dissipation solution. Its core working principle is: hot air generated by the frequency converter is guided to an air-water heat exchanger through internal air ducts, where cooling water removes the heat. Finally, the cooled air is returned to the frequency converter or exhausted outdoors. The heat dissipation principle is as follows: Figure 10 As shown.

[0004] However, this cooling method has a critical problem: due to the large temperature difference on the surface of the air-water heat exchanger, a large amount of condensate will be generated. If this condensate accumulates at the bottom of the equipment, it will not only cause corrosion of internal components, but more seriously, it may cause short circuits in electrical components, creating a safety hazard.

[0008] Furthermore, the water collection tank includes a water collection tank shell, and the interior of the water collection tank shell is provided with a liquid level sensor mounting beam and several supporting crossbeams. The supporting crossbeams are connected to the air-water heat exchanger through fixed bending plates. A limiting bending plate is also provided inside the right side of the water collection tank shell.

[0009] Furthermore, the automatic condensate drainage system includes a liquid level sensor, which is connected to the liquid level sensor mounting beam via a liquid level sensor fixing nut.

Detailed Implementation

[0029] like Figure 1-9 As shown, an air-water cooling device includes a housing 1, a water collection tank 4 inside the housing 1, an air-water heat exchanger 2 above the water collection tank 4, an inlet 201 and an outlet 202 connected to the left side of the air-water heat exchanger 2, the inlet 201 being located above the outlet 202, an automatic condensate drainage system on the water collection tank 4, a fan 8 installed on the top of the housing 1, and a control cabinet 7 installed inside the housing 1.

[0030] The water collection tank 4 includes a water collection tank shell 401. Inside the water collection tank shell 401, a liquid level sensor mounting beam 402 and several supporting crossbeams 403 are welded. The liquid level sensor mounting beam 402 is configured as an inverted C-shape. Both ends of the liquid level sensor mounting beam 402 are welded to the water collection tank shell 401 to enhance structural strength and support the air-water heat exchanger. The liquid level sensor 3 is fixed by a nut through the first mounting hole 40201 on the liquid level sensor mounting beam 402. The supporting crossbeams 403 are configured as inverted C-shapes. In addition to having the same support function as the liquid level sensor mounting beam 402, the supporting crossbeams 403 are also connected to the air-water heat exchanger 2 through a fixed bending plate 10. The height of the liquid level sensor mounting beam 402 and the supporting crossbeam 403 is lower than the height of the water collection tank housing 401, ensuring that condensate will not overflow along the crossbeam. Their special shape also allows condensate to flow freely within the tank. A limiting bend plate 404 is welded to the inside of the right side of the water collection tank housing 401. The supporting crossbeam 403 has a second mounting hole 40301 for connecting to the fixing bend plate 10. The upper surface of the limiting bend plate 404 is lower than the upper edge of the water collection tank housing 401 to prevent condensate from flowing out. Its main function is to provide a limit when installing the air-to-water heat exchanger 2. The edge of the water collection tank housing 401 is provided with fixing lugs for connecting to the air-to-water heat exchanger 2. The entire structural design ensures effective collection and discharge of condensate while maintaining the stability of the water collection tank structure.

[0031] The automatic condensate drainage system includes a liquid level sensor 3, which is connected to the liquid level sensor mounting beam 402 by a liquid level sensor fixing nut 9. A water collection tank drain pipe 405 is welded to the lower right side wall of the water collection tank housing 401 for draining condensate. An electric ball valve 5 is installed between the water collection tank drain pipe 405 and the air-cooled equipment drain pipe 6.

[0032] The automatic condensate drainage system of the air-cooled water-cooled equipment achieves automatic drainage through the linkage control of the liquid level sensor 3 and the electric ball valve 5. When condensate continuously accumulates in the water collection tank 4 and reaches the high water level set by the liquid level sensor 3, the normally open contact inside the liquid level sensor 3 closes and changes to a normally closed state. This signal change activates the contactor control circuit in the control cabinet 7, energizes the contactor coil, and then connects the power supply to the electric ball valve 5, causing it to open and the condensate to drain. As the water level drops to the preset low water level, the contactor of the liquid level sensor 3 returns to the normally open state, the contactor control circuit disconnects, the contactor coil is de-energized and disconnects, and the electric ball valve 5 automatically closes due to power failure. At this time, the water collection tank 4 returns to a sealed state and stops draining.

[0033] This invention utilizes an innovative condensate collection and automatic drainage system to effectively manage the condensate from air-cooled water-cooled equipment. Employing automatic water level detection technology, the system proactively controls the drainage process based on changes in the water level in the collection tank, completely eliminating safety hazards such as equipment corrosion and electrical short circuits caused by condensate accumulation in traditional equipment. This solution not only significantly improves the safety and reliability of equipment operation but also effectively extends the equipment's service life by preventing moisture retention and corrosion, providing a reliable guarantee for the stable operation of industrial equipment.
