Description

Technical Field

[0001] The present invention belongs to the technical field related to the housing or structural parts of electrical equipment, and specifically relates to improvements that facilitate cooling, ventilation or heating, and more particularly to a thyristor module with high heat dissipation performance and a working method thereof. Background Art

[0002] A thyristor array is a circuit structure formed by combining multiple thyristor devices in a certain way. In scenarios where ultra-high power loads need to be controlled, such as speed regulation of large industrial motors, high-voltage direct current transmission systems, and large power conversion devices, the current and voltage handling capabilities of a single thyristor are often difficult to meet the requirements. By combining multiple thyristors into an array, higher power handling capabilities can be achieved, and they can jointly bear large currents and high voltages, thereby effectively controlling high-power loads.

[0003] In the related art, liquid cooling is generally used to dissipate heat from thyristor modules; however, when controlling ultra-large power loads, the heat generated by a single thyristor chip can reach up to 125 degrees. During the liquid cooling process, the temperature of the water coolant rises, and the air originally dissolved in the water may form bubbles at the contact point between the water cooling head and the chip, thereby affecting the heat dissipation effect. Even some additives or corrosion inhibitors in the water cooling liquid may oxidize and decompose at high temperatures to form flocs that adhere to the contact point between the water cooling head and the chip.

[0004] Therefore, how to solve the technical problem that when liquid cooling is used, the position where the water cooling head contacts the chip will produce bubbles and flocs due to high temperature, which will affect the heat dissipation effect is urgently needed to be solved by technical personnel in this field.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, in the drawings, the thickness of the components may be exaggerated or reduced in order to effectively describe the technical content.

[0025] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0026] like Figure 1 , Figure 2 As shown, at least one embodiment provides a thyristor module with high heat dissipation performance, including: a thyristor array unit 1 and a plurality of water cooling head units 2, each water cooling head unit 2 dissipates heat for a corresponding thyristor device group 10 in the thyristor array unit 1.

[0027] like Figure 1 As shown, in some embodiments, the thyristor array unit 1 includes: a plurality of thyristor device groups 10, each thyristor device group 10 includes nine thyristor devices 11 arranged in a matrix, and the nine thyristor devices 11 form an axial ring 111, an inner ring 112 and an outer ring 113.

[0028] like Figure 2 As shown, in some embodiments, each thyristor device group 10 corresponds to a water cooling head unit 2, and the water cooling head unit 2 includes: an upper chamber 21, a lower chamber 22, a jet nozzle 23 and a trigger block group 24, and the outer surface of the lower chamber 22 is in contact with all the thyristor devices 11 in the thyristor device group 10 to dissipate heat.

[0029] Specifically, the jet nozzle 23 is rotatably arranged, with one end located in the upper chamber 21 and the other end located in the lower chamber 22 , so as to guide the cooling medium in the upper chamber 21 into the lower chamber 22 , thereby dissipating the heat of the thyristor device 11 .

[0030] In this embodiment, in order to clean the bubbles and flocs attached to the corresponding areas of each thyristor device 11 in the lower chamber 22, the jet nozzle 23 is set toward the area where the inner ring 112 is located, so that during the rotation of the jet nozzle 23, the sprayed cooling medium can impact the area corresponding to the inner ring 112 on the lower chamber 22; at the same time, during the rotation of the jet nozzle 23, the cross-sectional area of ​​the outlet of the jet nozzle 23 is changed by the pressurization of the trigger block group 24, thereby increasing the flow rate of the medium sprayed from the jet nozzle 23, so that the medium can clean the area corresponding to the outer ring 113 on the lower chamber 22.

[0031] like Figure 3As shown, in some embodiments, the inlet end 231 of the jet nozzle 23 is located in the upper chamber 21, and the first outlet end 232 of the jet nozzle 23 is located in the lower chamber 22. The cooling medium enters from the inlet end 231 and is ejected from the first outlet end 232. In order to make the jet nozzle 23 rotate, an impeller 233 is arranged at the inlet end 231, so that the impeller 233 rotates when being flushed by the medium in the water-cooling tube 3, thereby driving the first outlet end 232 to revolve.

[0032] like Figure 4 As shown, in some embodiments, in order to clean the area corresponding to the inner ring 112 on the lower chamber 22, the inclination angle of the first outlet end 232 is set toward the area where the inner ring 112 is located; in order to clean the area corresponding to the outer ring 113 on the lower chamber 22, the end side wall of the first outlet end 232 is set as a rotatable lower pressure plate 234, and the hinged part of the lower pressure plate 234 is provided with a coil spring 235, so that when the first outlet end 232 revolves, the lower pressure plate 234 can be rotated by squeezing the trigger block group 24, thereby changing the injection speed of the first outlet end 232.

[0033] like Figure 5 As shown, in some embodiments, the trigger block group 24 includes: a plurality of trigger blocks 240 , and the trigger block 240 includes: a mounting chamber 241 , a lifting block 242 and a first return spring 243 .

[0034] Specifically, the lifting block 242 is slidably disposed in the installation chamber 241 , the first return spring 243 is located in the installation chamber 241 , and two ends thereof respectively abut against the installation chamber 241 and the lifting block 242 to make the lifting block 242 protrude from the installation chamber 241 .

[0035] In this embodiment, the stiffness of the first return spring 243 is greater than the stiffness of the coil spring 235, so that when the lifting block 242 presses the lower pressing plate 234, only the lower pressing plate 234 rotates, and the lifting block 242 does not rise or fall.

[0036] In some embodiments, the lifting blocks 242 in each trigger block 240 have the same length so as to clean the area corresponding to the outer ring 113 on the lower chamber 22 .

[0037] In this embodiment, by setting the lengths of the lifting blocks 242 to be the same, the rotation angles of the lower pressing plate 234 can be kept consistent, so that the medium can be sprayed at the same distance under the premise of the same flow rate.

[0038] like Figure 6As shown, in some embodiments, a valve plate 31 is provided in the water-cooling tube 3, one end of the valve plate 31 extends into the pressure chamber 32, and the other end is connected to the second return spring 33; the valve plate 31 is configured to adjust the extension length according to the air pressure in the pressure chamber 32, that is, the flow rate of the medium in the water-cooling tube 3 is adjusted by the extension length of the valve plate 31 to change the revolution speed of the first outlet port 232.

[0039] In this embodiment, the valve plate 31 is used to open and close the water cooling pipe 3 , and the flow rate of the medium is changed by changing the cross-sectional area in the water cooling pipe 3 , thereby adjusting the rotation speed of the impeller 233 .

[0040] like Figure 5 , Figure 6 As shown, in some embodiments, each installation chamber 241 is connected to the pressure chamber 32 through an air duct 244; a protrusion 236 is provided on the rotating side of the first outlet end 232; the protrusion 236 is configured to pressurize the installation chamber 241 by squeezing the lifting block 242 during the rotation of the first outlet end 232, that is, to increase the air pressure in the pressure chamber 32 to make the valve plate 31 retreat, thereby reducing the orbital speed of the first outlet end 232 by reducing the flow rate of the medium in the water-cooling tube 3.

[0041] In this embodiment, when the protrusion 236 squeezes the lifting block 242, the lifting block 242 retreats and squeezes the installation chamber 241. Since the installation chamber 241 is connected to the pressure chamber 32 through the air channel 244, the air pressure in the pressure chamber 32 increases, thereby pushing the valve plate 31 backward to increase the cross-sectional area in the water-cooling pipe 3. At this time, the flow rate of the medium will decrease, thereby reducing the rotation speed of the first outlet port 232.

[0042] In some embodiments, since the thyristor device 11 in the outer ring 113 is farther away from the first outlet end 232, the impact force received by the area where the outer ring 113 is located is smaller than that of the inner ring 112; therefore, the protrusion 236 is set on the rotating side of the first outlet end 232, so that the first outlet end 232 is decelerated in advance before it rotates to the thyristor device 11 in the outer ring 113, thereby increasing the cleaning time.

[0043] like Figure 3 As shown, in some embodiments, the jet nozzle 23 further includes: a second outlet end 237 located in the lower chamber 22; the second outlet end 237 cleans the area corresponding to the upper shaft ring 111 of the lower chamber 22.

[0044] At least one embodiment also provides a working method of a thyristor module with high heat dissipation performance, which includes: flushing the impeller 233 with the medium in the water-cooling tube 3 to rotate the jet nozzle 23; through the rotation of the jet nozzle 23, the first outlet end 232 cooperates with the trigger block group 24 to clean the area corresponding to each thyristor device 11 on the lower chamber 22.

[0045] In some embodiments, the method of cleaning the area corresponding to each thyristor device 11 on the lower chamber 22 by rotating the jet nozzle 23 so that the first outlet end 232 includes: cleaning the area corresponding to the inner ring 112 on the lower chamber 22 through the first outlet end 232 in an unpressurized state; changing the injection speed of the first outlet end 232 through the extrusion of the trigger block group 24, so that the first outlet end 232 cleans the area corresponding to the outer ring 113 on the lower chamber 22.

[0046] For the specific structure and implementation process of the thyristor module with high heat dissipation performance, please refer to the relevant discussion in the above embodiments, which will not be repeated here.

[0047] In summary, the thyristor module with high heat dissipation performance and its working method change the injection speed of the jet nozzle 23 through the trigger block group 24, so that the jet nozzle 23 can clean the bubbles and flocs in the area corresponding to the inner ring 112 and the outer ring 113 in the lower chamber 22, thereby improving the heat dissipation effect; at the same time, in order to make the outer ring 113 have a cleaning effect close to that of the inner ring 112, the trigger block group 24 is used to reduce the rotation of the jet nozzle 23 when it is facing the thyristor device 11 of the outer ring 113, thereby increasing the cleaning time.

[0048] Herein, when it is mentioned that a first component is located on a second component, this may mean that the first component may be directly formed on the second component, or a third component may be interposed between the first component and the second component.

[0049] In this article, when an element or layer is referred to as being "located on," "engaged to," "connected to," "attached to," or "coupled to" another element or layer, it may be directly located on, engaged, connected, attached to, or coupled to another element or layer, or there may be intermediate elements or layers.

Other words used to describe the relationship between elements should be interpreted in a similar manner (e.g., "between" versus "directly between," "adjacent" versus "directly adjacent," etc.). As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0050] Herein, example embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as "at least one of..." modify the entire list of elements when following a list of elements, rather than modifying individual elements in the list. For example, the expression "at least one of a, b, and c" should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0051] The terms used herein are only used to describe specific exemplary configurations and are not intended to be limited. As used herein, the singular articles "one", "an" and "the" may also be intended to include plural forms, unless it is clearly indicated above that this is not the case. The terms "comprise", "include" and "have" are inclusive, and therefore specify the presence of features, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components and / or combinations thereof. The method steps, processes and operations described herein should not be interpreted as necessarily requiring them to be performed in the specific order discussed or shown, unless specifically identified as an execution order.

[0052] As used herein, the phrases "in one embodiment," "according to one embodiment," "in some embodiments," and the like generally refer to the fact that the particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of the present disclosure. Therefore, a particular feature, structure, or characteristic may be included in more than one embodiment of the present disclosure, so that these phrases do not necessarily refer to the same embodiment. As used herein, the terms "example," "exemplary," and the like are used to "serve as an example, instance, or illustration." Any implementation, aspect, or design described herein as "example" or "exemplary" is not necessarily to be construed as preferred or superior to other implementations, aspects, or designs. On the contrary, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

In addition, terms such as "first", "second" and other numerical terms do not imply an order or sequence when used in this document unless explicitly indicated above. Therefore, without departing from the teachings of the example embodiments, the first element, component, region, layer or section discussed above may be referred to as a second element, component, region, layer or section.

[0055] Spatially relative terms, such as "inside", "outside", "below", "below", "down", "above", "on", etc., may be used herein to facilitate description of the relationship of one element or feature to another element or feature as illustrated in the figure. In addition to the orientation depicted in the figure, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is turned over, the elements described as "below" or "below" other elements or features will be oriented to be "above" other elements or features. Therefore, the example term "below" can cover the orientation above and below. The device can be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0056] In the above discussion, unless otherwise stated, the terms "about," "approximately," "substantially," etc., when used to describe a numerical value, mean a variation of + / - 10% of the value.
