Description

Technical Field

[0001] This invention belongs to the field of water cooling technology, specifically relating to a water cooling system for a converter. Background Technology

[0002] A converter is an electrical device that changes the voltage, frequency, number of phases, and other electrical quantities or characteristics of a power supply system. In practical applications, some situations require converting AC power to DC power, which is the function of a rectifier circuit. In other situations, DC power needs to be converted to AC power; this reverse process, corresponding to rectification, is defined as an inverter circuit. Under certain conditions, a thyristor circuit can function as both a rectifier and an inverter circuit; such a device is called a converter. Existing converters are often installed in electrical boxes. Because converters are electrical devices, they generate a large amount of heat during operation due to the current heating effect, causing the internal temperature of the box to rise and affecting the operation of the electronic components inside.

[0003] To reduce the temperature inside the chassis, cooling devices are often installed inside the chassis. In order to improve the cooling effect, existing cooling devices often have multiple pipes arranged around the electrical components, which makes the space inside the chassis crowded, which is not conducive to electrical work. In addition, the crowded space makes it difficult for heat to dissipate, affecting heat dissipation. Summary of the Invention

[0004] The purpose of this invention is to provide a water-cooling system for a converter that is simple in structure and reasonably designed in order to solve the above problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A water-cooling system for a converter includes a housing, a converter housed within the housing, a cooling tank housed within the housing, a water pump, a water supply pipe, and a water-cooling pipe mounted on the cooling tank. The water supply pipe, water-cooling pipe, and cooling tank are interconnected and arranged around the circumference of the converter. The water pump injects coolant from the cooling tank into the water supply pipe, and the coolant in the water supply pipe enters the water-cooling pipe and finally enters the cooling tank. The water path is arranged around the circumference of the converter, and the water-cooling pipe consists of a water-passing section and an expansion section, which are arranged alternately.

[0007] As a further optimization of the present invention, both ends of the expansion section are sleeved on the water passage section, a water passage groove is provided in the middle of the water passage section, and a first clearance groove is also opened on the inner wall of the water passage section. A rotating member is provided in the water passage section, and a second rod is provided on the surface of the rotating member. The second rod is inserted into the second clearance groove.

[0008] As a further optimization of the present invention, the two ends of the water passage are eccentrically arranged. When the water flow impacts the rotating part through the water passage, the water flow impacts one side of the rotating part due to the eccentric arrangement of the water passage opening. At this time, the rotating part is subjected to force on one side and rotates under the impact of the water flow.

[0009] As a further optimization of the present invention, a second clearance groove is also provided on the inner wall of the water passage section. The second clearance groove is arranged at intervals along the circumference of the water passage section. A first rod is slidably provided in the second clearance groove and slides along the radial direction of the water passage section.

[0010] As a further optimization of the present invention, the surface of the expansion section is provided with a clearance through hole, and a through rod is provided in the clearance through hole, which is connected to the first rod.

[0011] As a further optimization of the present invention, the rotating component is composed of a central plate and a surrounding sleeve. The surface of the surrounding sleeve is provided with extrusion protrusions. Water flows out from the slot of the eccentrically arranged water channel and impacts the surface of the central plate. The central plate rotates under the impact of the water flow. The extrusion protrusions follow the rotation of the central plate and extrude pressure on the first rod. The first rod slides outward along the radial direction of the water passage section. The through rod moves with the first rod and expands the expansion section, thereby achieving the purpose of increasing the diameter of the expansion section.

[0012] As a further optimization of the present invention, the surrounding sleeve is spherical and has a hollow mesh structure.

[0013] As a further optimization of the present invention, the inner wall of the expansion section is also provided with a support groove, which is connected to the clearance through hole.

[0014] As a further optimization of the present invention, the support groove is provided with multiple sets of support members, each consisting of a first support rod and a second support rod. The first support rod and the second support rod are in contact with each other, and the first support rod and the second support rod are respectively connected to adjacent through rods.

[0015] As a further optimization of the present invention, a temperature sensor is also provided on the cooling box, which is used to monitor the temperature of the converter.

[0016] The beneficial effects of this invention are as follows: By setting up a support member, when the expansion section expands, the through rod moves under the action of the first rod, expanding the diameter of the expansion section. When the through rod moves, there is a relative displacement between it and the support member connected to it, so that the inner wall of the expansion section after expansion is always supported by the support member, further expanding the diameter of the expansion section and avoiding the situation where the expansion section shrinks due to atmospheric pressure after expansion.

[0017] This invention incorporates an expansion section. At normal temperatures, the water flow rate in the water pipe is relatively slow. When the water flow impacts the central plate, the central plate rotates and then returns to its original position under the action of a torsion spring. Thus, the expansion section forms a state of expansion and contraction, driving airflow and improving heat dissipation efficiency at normal temperatures. Attached Figure Description

[0026] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] Example 1

[0028] like Figures 1 to 7As shown, a water-cooling system for a converter includes a housing 6, a converter housed within the housing 6, and a cooling tank 1 housed within the housing 6. The cooling tank 1 is equipped with a water pump 2, a water supply pipe 3, and a water-cooling pipe 4. The water supply pipe 3 and the water-cooling pipe 4 are interconnected with the cooling tank 1 and arranged around the circumference of the converter. The water pump 2 injects coolant from the cooling tank 1 into the water supply pipe 3. The coolant in the water supply pipe 3 enters the water-cooling pipe 4 and finally enters the cooling tank 1, achieving water circulation. The water circulation is arranged around the circumference of the converter to achieve water-cooled heat dissipation treatment of the converter. The water-cooling pipe 4 consists of a water passage section 41 and an expansion section 42, which are arranged alternately. When the internal temperature of the housing 6 is too high, the expansion section 42 expands, increasing the water flow rate, improving the heat exchange effect of the converter, and enhancing the heat dissipation effect of the converter.

[0029] Both ends of the expansion section 42 are fitted onto the water passage section 41. A water passage groove 414 is provided in the middle of the water passage section 41. The two ends of the water passage groove 414 are eccentrically set. The inner wall of the water passage section 41 is also opened with a first clearance groove 411. A rotating component 43 is provided in the water passage section 41. A second rod 431 is provided on the surface of the rotating component 43. The second rod 431 is inserted into the first clearance groove 411. When the water flow impacts the rotating component 43 through the water passage groove 414, the water flow impacts one side of the rotating component 43 because the groove opening of the water passage groove 414 is eccentrically arranged. At this time, one side of the rotating component 43 is subjected to force and rotates under the impact of the water flow.

[0030] It should be noted that the second rod 431 is connected to the first clearance groove 411 by a torsion spring. When there is no water flow inside the water passage section 41, the second rod 431 is reset under the action of the torsion spring, which drives the rotating part 43 to return to its initial state.

[0031] The inner wall of the water passage section 41 is also provided with a second clearance groove 412. The second clearance groove 412 is arranged at intervals along the circumference of the water passage section 41. A first rod 413 is slidably provided in the second clearance groove 412. The first rod 413 slides along the radial direction of the water passage section 41.

[0032] It should be noted that the first rod 413 is connected to the water passage section 41 by a reset member, which is a spring in this embodiment.

[0033] The surface of the expansion section 42 is provided with a clearance through hole 421, and a through rod 422 is provided in the clearance through hole 421. The through rod 422 is connected to the first rod 413.

[0034] The rotating component 43 consists of a central plate 433 and a surrounding sleeve 434. The surrounding sleeve 434 is spherical and has a hollow mesh shape. The surface of the surrounding sleeve 434 is provided with extrusion protrusions 432. Water flows out from the slot of the eccentrically arranged water channel 414 and impacts the surface of the central plate 433. The central plate 433 rotates under the impact of the water flow. The extrusion protrusions 432 follow the rotation of the central plate 433 and extrude pressure on the first rod 413. The first rod 413 slides outward along the radial direction of the water passage section 41. The through rod 422 moves with the first rod 413 and expands the expansion section 42, thereby increasing the diameter of the expansion section 42. It should be noted that in the initial state, the plate surface of the central plate 433 is perpendicular to the central axis of the expansion section 42, and the hollow mesh spherical surrounding sleeve 434 can act as a filter screen to filter impurities in the water flow.

[0035] The inner wall of the expansion section 42 is also provided with a support groove, which is connected to the clearance through hole 421. Multiple sets of support members 423 are provided in the support groove. The support member 423 is composed of a first support rod and a second support rod. The first support rod and the second support rod are in contact with each other. The first support rod and the second support rod are respectively connected to the adjacent through rod 422. When the expansion section 42 expands, the through rod 422 moves under the action of the first rod 413, expanding the diameter of the expansion section 42. When the through rod 422 moves, there is a relative displacement between the support members 423 connected to it, so that the inner wall of the expansion section 42 after expansion is always supported by the support members 423, further expanding the diameter of the expansion section 42. This avoids the situation where the expansion section 42 shrinks due to atmospheric pressure after expansion, which would affect its heat dissipation efficiency.

[0036] The cooling box 1 is also equipped with a temperature sensor 5, which is used to monitor the temperature of the converter. When the temperature of the converter is too high, the temperature sensor 5 senses the high temperature signal and sends a signal to the water pump 2. The water pump 2 accelerates its operation and increases the flow rate of the water.

[0037] It should be noted that the water cooling system of this converter, during operation, first fills the cooling tank 1 with water. When the temperature is low, the cold water in the cooling tank 1 flows along the water pipe 3 under the action of the water pump 2, providing water cooling heat dissipation for the converter placed inside the chassis 6. When the temperature is too high, the temperature sensor 5 detects the high temperature signal and sends a signal to the water pump 2, causing the water pump 2 to accelerate and increase the water flow speed. The accelerated water flow passes through the water pipe 3, and the water flows sequentially through the water passage section 41 and the expansion joint. In the expansion section 42, when water flows through the water channel 414 on the water passage section 41 and impacts the rotating member 43, due to the eccentric arrangement of the channel opening 414, the water flow impacts one side of the rotating member 43. At this time, one side of the rotating member 43 is under force, and the middle plate 433 rotates under the impact of the water flow. The pressing protrusion 432 rotates with the middle plate 433, pressing the first rod 413. The first rod 413 slides outward along the radial direction of the water passage section 41, and the through rod 422 follows... As the first rod 413 moves, the expansion section 42 is opened, thereby increasing the diameter of the expansion section 42. When the expansion section 42 expands, the through rod 422 moves under the action of the first rod 413, expanding the diameter of the expansion section 42. When the through rod 422 moves, the relative displacement occurs between it and the support member 423 connected to it, so that the inner wall of the expanded section 42 is always supported by the support member 423, further increasing the diameter of the expansion section 42. This avoids the situation where the expansion section 42 shrinks due to atmospheric pressure after expansion, which would affect its heat dissipation efficiency. This achieves heat dissipation treatment for the inverter inside the housing 6. At normal temperature, the water flow rate in the water pipe 3 is relatively slow. When the water flow impacts the middle plate 433, the middle plate 433 rotates and then returns to its original position under the action of the torsion spring. Therefore, the expansion section 42 will form a state of expansion and contraction, driving air flow and improving the heat dissipation efficiency at normal temperature.

[0038] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
