Technical Field

[0001] This application relates to the field of electronic equipment technology, and in particular to a cooling structure and electronic equipment. Background Technology

[0002] Currently, the internal structure of commonly used liquid-cooled cold plates (such as fins and cold plates) is prone to accumulating biofilm, deposits or other impurities during long-term operation. These deposits can block microchannels, reduce the flow rate of coolant inside the cold plate, weaken heat dissipation performance, and may eventually lead to heat dissipation failure, causing system failure of electronic equipment.

[0003] In related technologies, ultrasonic or chemical cleaning is performed by disassembling the cold plate. However, manual disassembly and cleaning are time-consuming and labor-intensive, require system shutdown, and increase maintenance costs. Moreover, chemical cleaning agents may corrode the cold plate material and cause environmental problems. Summary of the Invention

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0018] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0019] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0020] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0021] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0022] Currently, electronic devices such as servers or computers generate a lot of heat during operation, especially memory modules (DIMMs). Therefore, heat dissipation devices are needed to assist in heat dissipation.

[0023] The internal structure of commonly used liquid-cooled cold plates (such as fins and cooling plates) is prone to accumulating biofilm, deposits or other impurities during long-term operation. These deposits can block microchannels, reduce the flow rate of coolant inside the cold plate, weaken heat dissipation performance, and may eventually lead to heat dissipation failure and system failure of electronic equipment.

[0024] In related technologies, an external filter is installed in the cooling circuit inside the cold plate, and ultrasonic or chemical cleaning is performed by disassembling the cold plate. However, the external filter cannot prevent deposits from forming directly inside the cold plate. Manual disassembly and cleaning are time-consuming and labor-intensive, require system shutdown, and increase maintenance costs. Moreover, chemical cleaning agents may corrode the cold plate material and cause environmental problems.

[0025] This application provides a cooling structure, referring to... Figures 1 to 6 The cooling structure includes a body 1, a cooling component 2, a cleaning component 3, and a driving component 4. The body 1 has a receiving space; the cooling component 2 is disposed within the receiving space; the cleaning component 3 is movably disposed within the receiving space for cleaning the cooling component 2; the driving component 4 is disposed on the outside of the body 1, and the driving component 4 includes a first actuating part 41. The cleaning component 3 includes a second actuating part 31 adapted to the first actuating part 41. The first actuating part 41 acts on the second actuating part 31, which can drive the cleaning component 3 to move relative to the cooling component 2 to clean the cooling component 2.

[0026] The cooling structure provided in this application embodiment has both the cleaning component 3 and the cooling component 2 disposed within the accommodating space of the main body 1, so that the cleaning component 3 can directly act on the cooling component 2 within the accommodating space without the need for external tools.

[0027] Since the cleaning component 3 is movably disposed within the receiving space and the driving component 4 is disposed on the outside of the main body 1, the first actuating part 41 of the driving component 4 is adapted to the second actuating part 31 of the cleaning component 3. Therefore, when the driving component 4 is activated, the first actuating part 41 can act on the second actuating part 31 to drive the cleaning component 3 to move or rotate relative to the cooling component 2, so that the cleaning component 3 can perform cleaning along each part of the surface of the cooling component 2 and remove impurities attached to the cooling component 2.

[0028] Since the cleaning process is automatically executed by the drive component 4, the operator only needs to operate the drive component 4 and does not need to perform disassembly and assembly procedures, which can reduce the frequency of manual maintenance and downtime for cleaning, and reduce production interruption or energy loss caused by downtime maintenance.

[0029] In addition, since the cleaning component 3 does not require disassembling the entire structure to clean the cooling component 2, it is easy to clean, thereby reducing the accumulation of dirt on the cooling component 2, reducing overheating or performance degradation caused by dirt accumulation, and also reducing the corrosion damage to the cooling component 2 caused by accumulated dirt.

[0030] In this embodiment, the body 1 is a supporting component of the cooling structure, providing a mounting base for the drive component 4, the cooling component 2, and the cleaning component 3. The internal accommodating space of the body 1 is a closed cavity containing coolant.

[0031] In some embodiments, the body 1 may be sealed to connect multiple pipes, which may be used to connect components that provide coolant or components that recover coolant, etc.

[0032] In this embodiment, the body 1 can be designed as a square or cylindrical structure with a hollow interior forming a receiving space. The body 1 can be formed by stamping a metal sheet, or it can be integrally formed from plastic or cast aluminum.

[0033] In this embodiment, the cooling component 2 is a heat exchange element that is fixed or installed in a housing space. It can exchange heat with an external heat source by introducing a liquid or gaseous cooling medium inside it. During operation, dust, oil, flocculent matter, or other impurities may accumulate on the cooling component 2.

[0034] For example, the cooling component 2 can be a finned heat exchanger, a water-cooled radiator, a heat pipe cooling module, or the cold end of a semiconductor refrigeration chip.

[0035] In this embodiment, the cleaning component 3 can move, rotate, swing, or reciprocate within the accommodating space. The main body 1 can be equipped with guide structures such as guide rails, grooves, or rotating shafts to restrict the movement of the cleaning component 3. The cleaning component 3 can be a brush, nozzle, or scraper to perform cleaning actions such as sweeping, blowing, or scraping.

[0036] For example, the cleaning component 3 can be designed as a brush plate with bristles, with both ends engaged in the slide rails on the inner wall of the body 1, and can slide up and down along the slide rails to clean the cooling component 2; the cleaning component 3 can also be designed as a rotatable disc brush, which is mounted on the bracket of the receiving space through the central rotating shaft, and rotates to clean the cleaning component 3.

[0037] In this embodiment, the drive component 4 is mounted on the outer surface of the body 1 or on an external independent bracket. The drive component 4 can be a motor, such as a stepper motor, a brushless DC motor or a geared motor, and is fixed to the outer wall or top flange of the body 1 by screws. The output shaft of the motor passes through the sealing hole on the wall of the body 1 and extends into the receiving space to drive the cleaning component 3 to move.

[0038] In some embodiments, the driving component 4 and the cleaning component 3 are each provided with mutually cooperating action structures (first action part 41 and second action part 31), and the first action part 41 and the second action part 31 are adapted in shape, size, tooth shape or magnetic pole.

[0039] In some embodiments, the first actuating part 41 may be a drive gear, eccentric cam, lead screw nut, permanent magnet or shift fork on the output shaft of the drive motor; the second actuating part 31 may be a rack, driven groove, threaded sleeve, ferromagnetic block or pin on the cleaning component 3.

[0040] For example, a drive gear (first action part 41) is installed at the output shaft end of the drive component 4, and a linear rack (second action part 31) is fixed at the upper end of the cleaning component 3. The gear meshes with the rack to convert the rotational motion into the linear reciprocating motion of the cleaning component 3.

[0041] In some possible embodiments of this application, reference is made to Figure 2 The driving component 4 is detachably disposed on the body 1, so that the driving component 4 has a first position and a second position. In the first position, the driving component 4 can drive the cleaning component 3 to move along the first direction X1. In the second position, the driving component 4 can drive the cleaning component 3 to move along the second direction X2. The first direction X1 and the second direction X2 are opposite.

[0042] In this embodiment, the connection between the drive component 4 and the body 1 is a detachable connection, meaning that the drive component 4 can be removed from the body 1 without damaging the structure of the body 1 or the drive component 4. This detachable connection allows the drive component 4 to be reinstalled in different positions on the body 1 or installed in different orientations.

[0043] Thus, the installation position or direction of the drive component 4 on the body 1 can be manually or automatically reassembled according to actual needs, thereby changing the output direction of the drive component 4 and giving the drive component 4 a first position and a second position.

[0044] For example, the drive component 4 (such as a motor assembly) can be fixed to the outer wall of the body 1 by means of screws or clips.

[0045] In this embodiment, the cleaning component 3 can be one, two or more. By adjusting the position of the driving component 4, the driving component 4 can be connected to different cleaning components 3 to drive the different cleaning components 3 to move.

[0046] In this embodiment, the first pose and the second pose refer to two different assembly states, which differ distinguishably in installation position and installation angle. For example, the first pose is to install the drive component 4 onto the first side of the body 1, and the second pose is to install the drive component 4 onto the second side of the body 1 opposite to the first side. Alternatively, the first pose is to install the drive component 4 onto the body 1 at a first angle, and the second pose is to install the drive component 4 onto the body 1 at a second angle.

[0047] In this embodiment, when the driving component 4 is assembled onto the body 1 in its first position, the driving force it outputs, through the cooperation of the first actuating part 41 and the second actuating part 31, causes the cleaning component 3 to move along the first direction X1 within the receiving space. This first direction X1 is directly related to the power output direction of the driving component 4 in its first position. When the driving component 4 is adjusted from its first position to its second position and reassembled onto the body 1, its power output direction or mode of action changes, thereby causing the movement direction of the cleaning component 3 to change accordingly to the second direction X2. The second direction X2 is different from the first direction X1.

[0048] It is understandable that in the first position and the second position, the driving component 4 can drive the cleaning component 3 to move along the first direction X1 and the second direction X2, respectively. Therefore, when it is necessary to change the cleaning movement direction, it is only necessary to remove the driving component 4 from the body 1 and reinstall it in another position to change the force direction of its first action part 41 on the second action part 31, without having to replace different driving components 4 or change the internal structure of the cleaning component 3.

[0049] Since the first direction X1 and the second direction X2 are opposite, the driving component 4 can drive the cleaning component 3 to move in opposite directions in two positions. This allows the cleaning component 3 to clean the cooling component 2 from both the forward and reverse paths, which can optimize problems such as dirt accumulation, squeezing or secondary adhesion that occur during unidirectional cleaning.

[0050] In some possible embodiments of this application, the first functional part 41 includes a first magnetic element 411, the second functional part 31 includes a second magnetic element 412, the magnetic poles of the first magnetic element 411 and the magnetic poles of the second magnetic element 412 are the same or opposite, and the first magnetic element 411 and the second magnetic element 412 are arranged opposite to each other.

[0051] In this embodiment, a first magnetic element 411 is provided in the first functional part 41. The first magnetic element 411 can generate a magnetic field and serve as the active end for power transmission. The first magnetic element 411 can be a permanent magnet, such as a neodymium magnet or a ferrite magnet; the first magnetic element 411 can also be an electromagnet, which can generate magnetism after being energized.

[0052] In this embodiment, a second magnetic element 412 is provided in the second functional part 31. The second magnetic element 412 can generate a magnetic field and serve as the passive end for power transmission. The second magnetic element 412 can be a permanent magnet, such as a neodymium magnet or a ferrite magnet; the second magnetic element 412 can also be an electromagnet, which can generate magnetism after being energized.

[0053] It is understandable that when the magnetic poles of the first magnetic element 411 and the second magnetic element 412 are the same, both the first magnetic element 411 and the second magnetic element 412 are either S poles or both are N poles. The two identical magnetic poles will generate a repulsive force, that is, the first magnetic element 411 can push the second magnetic element 412 away. When the magnetic poles of the first magnetic element 411 and the second magnetic element 412 are opposite, one of the first magnetic element 411 and the second magnetic element 412 is an S pole and the other is an N pole. The S pole and the N pole will generate an attractive force, that is, the first magnetic element 411 can attract the second magnetic element 412 closer.

[0054] In this embodiment, the first magnetic element 411 and the second magnetic element 412 are separated by the body 1 and are arranged opposite each other in space. Thus, the first direction X1 and the second direction X2 are parallel to the arrangement direction of the first magnetic element 411 and the second magnetic element 412.

[0055] For example, the first magnetic element 411 and the second magnetic element 412 are arranged along the first direction X1. The first magnetic element 411 can be an electromagnet and the second magnetic element 412 can be a permanent magnet. By changing the direction of the current flowing into the electromagnet, the direction of the magnetic pole of the electromagnet is changed. In this way, the permanent magnet can be driven to reciprocate along the first direction X1 in the body 1 to move closer to and away from the electromagnet, so as to realize the function of cleaning and cooling component 2.

[0056] Since the first magnetic element 411 is located on the drive component 4, i.e., the outside of the body 1, and the second magnetic element 412 is located on the cleaning component 3, i.e., inside the body 1, the driving force can be transmitted from the outside of the body 1 through the magnetic field to the interior of the receiving space, thus eliminating the need to create through holes in the wall of the body 1 for the drive shaft or connecting rod to pass through. Therefore, the sealing problem caused by drilling can be optimized, and the leakage of condensate or refrigerant gas in the receiving space can be reduced.

[0057] In some possible embodiments of this application, the driving component 4 includes two first actuating parts 41, one of which includes a first magnetic element 411, and the other includes a second magnetic element 412 with the opposite magnetic pole to the first magnetic element 411; the cleaning component 3 includes two second actuating parts 31, one of which includes a third magnetic element 311, and the other includes a fourth magnetic element 312 with the opposite magnetic pole to the third magnetic element 311; in a first position, the first magnetic element 411 is disposed corresponding to the third magnetic element 311 and their magnetic poles are opposite, and the second magnetic element 412 is disposed corresponding to the fourth magnetic element 312 and their magnetic poles are opposite; in a second position, the first magnetic element 411 is disposed corresponding to the fourth magnetic element 312 and their magnetic poles are the same, and the second magnetic element 412 is disposed corresponding to the third magnetic element 311 and their magnetic poles are the same.

[0058] For example, refer to Figure 3 and Figure 4 , Figure 3 The diagram shows a structure where the first magnetic element 411 and the third magnetic element 311 are correspondingly arranged in the first direction X1, and the second magnetic element 412 and the fourth magnetic element 312 are correspondingly arranged in the first direction X1. At this time, the driving member 4 is in the first position, and the magnetic poles of the first magnetic element 411 and the third magnetic element 311 are opposite, i.e., the first magnetic element 411 is the S pole and the third magnetic element 311 is the N pole. The magnetic poles of the second magnetic element 412 are opposite to those of the fourth magnetic element 312, i.e., the second magnetic element 412 is the N pole and the fourth magnetic element 312 is the S pole. With this structure, the driving member 4 can drive the cleaning member 3 to move away from the second magnetic element 412 along the first direction X1, i.e., the cleaning member 3 moves towards the cooling member 2 and contacts the cooling member 2 to clean the cooling member 2 along the first direction X1.

[0059] Based on this, the operator can disassemble the drive component 4 and rotate it 180 degrees to install it onto the main body 1. At this time, as... Figure 4 As shown, the first magnetic element 411 corresponds to the fourth magnetic element 312, and the second magnetic element 412 corresponds to the third magnetic element 311. The first magnetic element 411 and the fourth magnetic element 312 have the same magnetic poles, i.e., the first magnetic element 411 is the S pole and the fourth magnetic element 312 is the S pole. The second magnetic element 412 and the third magnetic element 311 have the same magnetic poles, i.e., the second magnetic element 412 is the N pole and the third magnetic element 311 is the N pole. With this structure, the driving component 4 can drive the cleaning component 3 to move along the second direction X2 towards the second magnetic element 412. That is, after moving relative to the cooling component 2 along the second direction X2, the cleaning component 3 moves towards the side closer to the second magnetic element 412, thus cleaning the cooling component 2 along the second direction X2.

[0060] Therefore, by rotating the drive component 4, the movement direction of the cleaning component 3 can be adjusted, so that the cleaning component 3 can reciprocate relative to the cooling component 2 within the body 1 along the first direction X1 and the second direction X2, thereby improving the cleaning effect.

[0061] In some possible embodiments of this application, the first magnetic element 411 and the second magnetic element 412 are distributed along a direction perpendicular to the first direction X1 and the second direction X2, and the third magnetic element 311 and the fourth magnetic element 312 are distributed along a direction perpendicular to the first direction X1 and the second direction X2.

[0062] In this embodiment of the application, the driving component 4 can be an integral structure, or the driving component 4 can be a structure formed by connecting the first action part 41 and the second action part 31.

[0063] In this embodiment of the application, in order to better transmit the magnetic force of the first magnetic element 411 and the second magnetic element 412 into the housing 12, the driving component 4 can be a plate-shaped structure and adapted to the shape of the outer wall of the housing 12.

[0064] For example, the body 1 has a rectangular structure, and the driving component 4 is a plate-shaped driving plate. The driving plate can be covered on the outer wall of the body 1 so that the driving plate is in close contact with the outer wall of the body 1. In this case, the arrangement direction between the driving plate and the housing 12 can be understood as the thickness direction of the driving plate or the thickness direction of the housing 12, which is parallel to the first direction X1 and the second direction X2.

[0065] Based on this, the direction perpendicular to the first direction X1 and the second direction X2 can be the extension direction of the drive plate and the upper wall of the housing 12, that is, the first magnet and the second magnet are arranged along the extension direction of the drive plate, and the specific arrangement is not limited.

[0066] For example, the direction perpendicular to the first direction X1 and the second direction X2 can be referred to as the third direction Y. A virtual central axis N is formed along the third direction Y through the center of the drive plate. The first magnetic element 411 and the second magnetic element 412 can be symmetrically arranged with respect to the virtual central axis N.

[0067] Thus, when the drive plate is rotated 180 degrees, the first magnetic element 411 and the fourth magnetic element 312 can be set accordingly, and the second magnetic element 412 and the third magnetic element 311 can be set accordingly, which facilitates the adjustment of the drive component 4.

[0068] In some possible embodiments of this application, the body 1 includes a housing 12 for forming a receiving space; a cleaning component 3 is movably disposed on the housing 12; in a cleaning state, a driving component 4 can drive the cleaning component 3 to move in a direction close to or away from the cooling component 2; in a non-cleaning state, the driving component 4 can restrict the movement of the cleaning component 3 relative to the housing 12, and the cleaning component 3 is located between the cooling component 2 and the housing 12.

[0069] In some embodiments, the drive component 4 can lock the cleaning component 3 using a self-locking motor, an electromagnetic brake, or a mechanical locking structure. Alternatively, a limiting structure, such as a protrusion or a slot, can be provided inside the housing 12, and correspondingly, a structure adapted to the protrusion or slot is provided on the cleaning component 3. In the non-cleaning state, the drive component 4 drives the cleaning component 3 to move to engage with the protrusion or slot, thereby limiting the position of the cleaning component 3 relative to the housing 12, thus reducing the movement of the cleaning component 3 within the housing 12 and reducing the interference of the cleaning component 3 with the cooling component 2 inside the housing 12.

[0070] Understandably, in the non-clean state, i.e., when the cooling structure is functioning normally and used to cool electronic components, there is no need for the cleaning component 3 to clean the cooling component 2. Therefore, the drive component 4 confines the cleaning component 3 within the housing 12, reducing the blockage of the cooling channels within the cooling component 2 by the movement of the cleaning component 3 and minimizing the impact on the cooling function. The clean state refers to the situation where the cooling component 2 requires cleaning.

[0071] For example, refer to Figure 1 , Figure 2 and Figure 6 The cooling component 2 includes a base plate 21, and multiple heat dissipation fins 22 of the cooling component 2 are disposed on the base plate 21. The housing 12 is sealed to the base plate 21 and the housing is enclosed to form an accommodating space. The multiple heat dissipation fins 22 are located in the accommodating space. There is a gap between the side of the multiple heat dissipation fins 22 away from the base plate 21 and the inner wall of the housing 12. In the non-cleaning state, the cleaning component 3 is located in the gap and does not interfere with the multiple heat dissipation fins 22, so as to reduce the obstruction of the cooling circuit formed between the multiple heat dissipation fins 22 and reduce the impact on the cooling function.

[0072] The cooling structure provided in this application embodiment can restrict the movement of the cleaning component 3 relative to the housing 12 when it is not being cleaned. The cleaning component 3 is located between the cooling component 2 and the housing 12. Therefore, when cleaning is not required, the driving component 4 can lock the cleaning component 3 so that it will not be accidentally displaced due to gravity, vibration or airflow impact. This will not interfere with the normal operation of the cooling component 2, nor will it cause abnormal noise or damage due to accidental movement that could impact the housing 12 or the cooling component 2.

[0073] In some possible embodiments of this application, the body 1 includes a threaded connection portion 11, the drive component 4 includes a connection hole 42, and a fastener can pass through the connection hole 42 and be threadedly connected to the threaded connection portion 11 to thread the drive component 4 onto the body 1; the body 1 includes a plurality of threaded connection portions 11, the drive component 4 includes a plurality of connection holes 42, the plurality of threaded connection portions 11 correspond one-to-one with the plurality of connection holes 42, and the plurality of threaded connection portions 11 are distributed along a direction perpendicular to the first direction X1.

[0074] In this embodiment, the fastener can be a screw or threaded rod with external threads on its outer circumference. The connecting hole 42 of the drive component 4 can also be provided with internal threads to achieve a stable connection with the fastener.

[0075] For example, refer to Figure 2The main body 1 includes a protruding threaded connection portion 11. The inner diameter of the connection hole 42 of the drive component 4 is larger than the outer diameter of the threaded connection portion 11, that is, the threaded connection portion 11 can extend into the connection hole 42 and cooperate with the inner wall of the connection hole 42. One end of the fastener is connected to the internal thread of the threaded connection portion 11, so that the fixing part of the other end of the fastener abuts against the area on the drive component 4 where the connection hole 42 is formed, thereby realizing the connection of the drive component 4 to the main body 1.

[0076] In this embodiment of the application, the threaded connection portion 11 on the body 1 may include multiple portions. For example, there may be four threaded connection portions 11 on the body 1, with the four threaded connection portions 11 respectively disposed at the four corners of the upper surface of the body 1, and the drive component 4 having corresponding connection holes 42.

[0077] The cooling structure provided in this application embodiment allows fasteners to pass through the connecting holes 42 of the drive component 4 and the threaded connecting parts 11 on the body 1, achieving a detachable connection between the drive component 4 and the body 1. The mechanism is simple and easy to disassemble due to the cooperation of the fasteners and threaded holes. Since the body 1 includes multiple threaded connecting parts 11 and the drive component 4 includes multiple connecting holes 42, and the multiple threaded connecting parts 11 correspond one-to-one with the multiple connecting holes 42, the drive component 4 needs to be fixed simultaneously by multiple sets of fasteners. This makes the installation posture of the drive component 4 more stable and accurate, and also makes the cooperation between the first working part 41 and the second working part 31 more stable.

[0078] In some possible embodiments of this application, the cooling component 2 includes a plurality of heat dissipation fins 22, and a cooling circuit is provided between adjacent heat dissipation fins 22. The cleaning component 3 includes a plurality of cleaning parts 32, which are disposed corresponding to the cooling circuit. The cleaning parts 32 are adapted to the outer contour of the heat dissipation fins 22. The cleaning parts 32 can extend into the cooling circuit and remove deposits on the heat dissipation fins 22.

[0079] Based on this, a cleaning component is provided in alignment with the heat dissipation fins 22 on the cooling component 2 for the cleaning section 32. The cleaning component can be nylon bristles, rubber scrapers, non-woven cloth wiping blocks, or high-pressure air jets. For example, the cleaning component is configured as a scraper structure, which can extend into the gap between adjacent heat dissipation fins 22 along the first direction X1 and the second direction X2. The scraper can contact the adjacent heat dissipation fins 22 and scrape off the deposits attached to the heat dissipation fins 22.

[0080] In some embodiments, the cleaning element of the cleaning part 32 can be made of a flexible material that can be deformed and extended between the heat dissipation fins 22. For example, the cleaning element can be a flexible brush bristle that is inserted into the gap between the heat dissipation fins 22 of the cooling component 2 to scrape off the dust and lint trapped between the fins.

[0081] In some embodiments, the cleaning section 32 of the cleaning component 3 can be adjusted according to the structure of the heat dissipation component, and this application does not limit this. For example, the cleaning section 32 can be a mesh brush structure, a comb-like structure, or a grid-like structure, etc.

[0082] For example, refer to Figure 4 and Figure 5 The cleaning section 32 is a rectangular plate structure adapted to the structure of the housing 12. The cleaning section 32 includes a plurality of grid-shaped cleaning sections 32. The cleaning section 32 is a hole that passes through the plate structure along the first direction X1. The shape of the cleaning section 32 is adapted to the heat dissipation fins 22. When the cleaning component 3 moves along the first direction X1, the heat dissipation fins 22 can extend into the cleaning section 32. The outer wall of the cleaning section 32 scrapes off the deposits on the heat dissipation fins 22. When the cleaning section 32 moves along the second direction X2, it carries the deposits away to the cooling medium in the body 1.

[0083] In some possible embodiments of this application, the cooling structure further includes a bypass filter, the cooling circuit in which the cooling component 2 is located is connected to the bypass filter, and when the cleaning component 3 is removed from the cooling component 2, the deposits removed from the cooling component 2 flow to the bypass filter with the coolant.

[0084] In this embodiment, the bypass filter is connected to the internal accommodating space of the main body 1, and a sealing element is provided at the connection between the bypass filter and the main body 1 to ensure the airtightness of the internal accommodating space of the main body 1.

[0085] In this embodiment of the application, the structure of the bypass filter is not limited. The bypass filter may have a filter structure inside, such as a filter screen, filter element or sintered body, which can be used to physically intercept and remove suspended impurities in the coolant.

[0086] The cooling structure provided in this application embodiment includes a bypass filter. When the cleaning component 3 scrapes off the deposits on the cooling component 2, the deposits can flow with the coolant. The bypass filter can filter the deposits in the coolant, allowing the coolant to be reused and reducing blockage or secondary pollution caused by the deposits flowing with the coolant.

[0087] On the other hand, embodiments of this application provide an electronic device, which includes electronic components and a cooling structure. The cooling structure is used to cool the electronic components. The cooling structure includes a body 1, a cooling component 2, a cleaning component 3, and a driving component 4. The body 1 has a receiving space. The cooling component 2 is disposed within the receiving space. The cleaning component 3 is disposed within the receiving space and is used to clean the cooling component 2. The driving component 4 is disposed on the outside of the body 1. The driving component 4 includes a first actuating part 41. The cleaning component 3 includes a second actuating part 31 adapted to the first actuating part 41. The first actuating part 41 acts on the second actuating part 31 and can drive the cleaning component 3 to move relative to the cooling component 2 to clean the cooling component 2.

[0088] In this embodiment, the electronic device can be a computer, server, or high-performance computer, etc. The electronic components can be memory modules (DIMMs), central processing units (CPUs), graphics processing units (GPUs), or other heat-generating chips.

[0089] The electronic device provided in this application embodiment has a cooling structure that can contact the electronic components. When the electronic components are working, they can generate heat, and the cooling structure can remove the heat. Both the cleaning component 3 and the cooling component 2 are disposed within the receiving space of the main body 1, so that the cleaning component 3 can act directly on the cooling component 2 within the receiving space without the need for external tools.

[0090] Since the cleaning component 3 is movably disposed within the receiving space and the driving component 4 is disposed on the outside of the main body 1, the first actuating part 41 of the driving component 4 is adapted to the second actuating part 31 of the cleaning component 3. Therefore, when the driving component 4 is activated, the first actuating part 41 can act on the second actuating part 31 to drive the cleaning component 3 to move or rotate relative to the cooling component 2, so that the cleaning component 3 can clean along each part of the surface of the cooling component 2 and remove impurities attached to the cooling component 2.

[0091] Since the cleaning process is automatically executed by the drive component 4, the operator only needs to operate the drive component 4 and does not need to perform disassembly and assembly procedures, which can reduce the frequency of manual maintenance and downtime for cleaning, and reduce production interruption or energy loss caused by downtime maintenance.

[0092] In addition, since the cleaning component 3 does not require disassembling the entire structure to clean the cooling component 2, it is easy to clean, thereby reducing the accumulation of dirt on the cooling component 2, reducing overheating or performance degradation caused by dirt accumulation, and also reducing the corrosion damage to the cooling component 2 caused by accumulated dirt.

[0093] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
