[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0049] It should be noted that in this embodiment, the directions or positional relationships indicated by "upper", "lower", "front", "back", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0050] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0051] Next, a server cabinet provided by an embodiment of the present invention is described in detail. Figure 1A schematic diagram of the internal structure of a server cabinet with a cabinet door 11 in an open state provided in an embodiment of the present invention, the server cabinet includes a cabinet body 1, a storage component 2, an injection component 3 and a positioning component 4, the interior of the cabinet body 1 is divided into a plurality of storage spaces for storing servers, in some embodiments, the storage spaces can be arranged in sequence from top to bottom, and a storage component 2 is installed in the storage space, and correspondingly, the storage components 2 are also arranged in sequence from top to bottom; it should be noted that a plurality of storage components 2 can be distributed vertically in the cabinet body 1, or can be staggered in the vertical direction; in addition, for the same storage space, at least one storage component 2 can be installed, or multiple storage components 2 can be installed horizontally, and no excessive restrictions are made here.

[0052] The storage component 2 includes a heat sink 21, which can be a heat sink fin. The heat sink fin is made of copper with good thermal conductivity and can effectively dissipate heat. The heat sink 21 itself has multiple fins, and there is a certain gap between adjacent fins to ensure a good heat dissipation effect; at the same time, the upper part of the heat sink 21 can be used to place the server, and through contact heat transfer, the heat of the server can be transferred to the heat sink 21, and the heat sink 21 can achieve heat dissipation.

[0053] Generally speaking, the server itself also has a heat dissipation function, including installing a radiator, using a cooling fan, etc. The cooling fan generates wind flow by rotating blades to discharge hot air from the inside of the server. In this embodiment, the hot air discharged by the cooling fan of the server can act on the heat sink 21, and the heat sink 21 can be used to further dissipate heat; or the radiator of the server can be directly in contact with the heat sink 21, and the heat can be further discharged outward through the heat sink 21 in the form of contact heat transfer.

[0054] The jet assembly 3 includes a jet component 31 connected to a high pressure gas source, see Figure 1 and Figure 3 The jet component 31 is provided with a plurality of jet holes 34 for exhausting air toward the heat sink 21. The jet component 31 may be a box-shaped structure or a tubular structure. For example, the jet component 31 is box-shaped as a whole, and a plurality of jet holes 34 are provided on the box-shaped structure for exhausting air, while the tubular structure may be directly connected to a high-pressure air source to form a plurality of jet pipes with the jet holes 34, thereby realizing jetting. However, it is worth noting that, for the jet pipe, the end portion with the jet hole 34 should have a certain stability, thereby ensuring that the jet hole 34 has a stable jetting direction.

[0055] Furthermore, the jet component 31 is movably arranged on one side of the storage component 2, and can correspond to the position of the heat sink 21 during the movement, so that the high-pressure gas ejected by the jet component 31 acts on the heat sink 21; but considering that when the high-pressure jet acts on the heat sink 21, although it has a certain dust removal effect, it cannot completely remove the dust in the gaps on the heat sink 21, therefore, in order to further improve the cleaning effect of the high-pressure jet on the heat sink 21, the jet hole 34 can be directly sprayed to the gap between the heat sink 21 sheets to ensure that the high-pressure gas can directly act on the gap between adjacent sheets, thereby spraying out the dust accumulated in the gaps of the heat sink 21, thereby improving the cleaning efficiency.

[0056] In some embodiments, since the heat sink 21 has more sheets and there can be gaps between adjacent sheets, the spacing between adjacent jet holes 34 can be set to be the same as the spacing between adjacent sheets to ensure that the jet holes 34 can act in the gaps between multiple groups of adjacent sheets at the same time, thereby improving the overall cleaning efficiency of the heat sink 21.

[0057] In other words, each jet hole 34 may correspond to the gap of the heat sink 21 during the jetting process toward the heat sink 21. However, since the cross-section of the gap between adjacent sheets is generally rectangular, the jet hole 34 needs to be set as a rectangular opening. For details, please refer to Fig. 9 , so that the high pressure jet can fully act in the gaps between adjacent heat sinks 21. If the jet member 31 of the jet pipe structure is adopted, a rectangular jet hole 34 can be set in the jet pipe, or a jet nozzle with a rectangular opening can be added, which will not be described in detail here.

[0058] In this embodiment, the gap of the heat sink 21 refers to the gap between adjacent sheets among the plurality of sheets constituting the heat sink 21 .

[0059] The positioning component 4 is connected to the jet component 31, and can drive the jet component 31 to correspond to the position of the heat sink 21 one by one, so that each heat sink 21 can be jet-cleaned. Specifically, the jet component 31, driven by the positioning component 4, can correspond to the heat sink 21 one by one according to the path set by the control unit. In this path, when the jet component 31 reaches the position corresponding to the heat sink 21, it should stay for a certain time to ensure that the high-pressure jet has enough time to clean the dust; or, the jet component 31, driven by the positioning component 4, can reach the corresponding position of any other heat sink 21 from the corresponding position of one heat sink 21 according to the position information recorded in the control unit, and can correspond to the position of each heat sink 21 without a specific movement path. In this case, a single or several heat sinks 21 can be quickly cleaned, and the jet component 31 can be prevented from staying at the heat sink 21 that does not need jet cleaning, thereby improving the overall cleaning efficiency.

[0060] When the jet component 31 moves along the setting path of the heat sink 21 in the cabinet 1 under the drive of the positioning component 4, the jet component 31 can correspond to each heat sink 21 on the movement path, and then perform high-pressure jets on the heat sink 21 on each storage component 2, which can achieve a more comprehensive cleaning effect. The above setting path expresses a distribution method, that is, when the heat sink 21 is distributed in a certain manner in the cabinet 1, such as vertical distribution, horizontal distribution or S-shaped distribution, the positioning component 4 can drive the jet component 31 to move according to the distribution method, that is, drive the jet component 31 to move vertically, horizontally or S-shaped, so that each heat sink 21 can be affected by the high-pressure jet.

[0061] For example, when the heat sinks 21 are distributed up and down at the same vertical position, the jet component 31 only needs to move from top to bottom to correspond to the heat sink 21 in each storage component 2; when the heat sink 21 is staggered in the vertical direction, that is, S-shaped, the jet component 31 needs to move horizontally while moving vertically to adapt to the staggered heat sink 21; and for placing multiple storage components 2 in the same storage space, the jet component 31 can be extended or moved to correspond to each heat sink 21 by increasing the length of the jet component 31 or moving the jet component 31 horizontally. It should be noted that the heat sink 21 on each storage component 2 has at least one side close to the jet component 31, and the side should be on the same side, so that the jet component 31 can correspond to the heat sink 21 on each storage component 2 by moving on one side.

[0062] In summary of the above embodiments, the present invention sprays the heat sink 21 with high-pressure gas sprayed by the jet component 3, thereby cleaning the dust on the heat sink 21; specifically, the jet component 3 includes a jet part 31, and a jet hole 34 is provided on the jet part 31. The jet part 31 can be movably arranged and can correspond to the position of the heat sink 21 during the movement, so that the jet hole 34 can spray into the gap between the heat sink 21 sheets to spray out the accumulated dust in the gap, and the heat sink components can be cleaned without opening the cabinet, thereby ensuring the heat dissipation effect of the heat sink components; at the same time, the jet part 31 is driven to move by the adjustment component 4, and according to the distribution position of the heat sink 21, the movement of the jet part 31 can be selectively controlled, so that the jet part 31 corresponds to the position of the heat sink 21 one by one, thereby ensuring the heat dissipation effect of all heat sinks 21 in the cabinet.

[0063] In some embodiments, please refer to Figure 1 A cabinet door 11 is provided on the opening side of the cabinet 1, a jet component 31 is movably provided on the cabinet door 11 and is located inside the cabinet 1, the storage space is located inside the cabinet 1, and the heat sink 21 in the storage component 2 can correspond to the jet component 31 on the opening side of the cabinet 1.

[0064] The jet assembly 3 also includes a high-pressure air pump 32 and a connecting hose 33, please refer to Figure 3 Since the jet component 31 is arranged on the cabinet door 11 and can move with the opening and closing of the cabinet door 11, the high-pressure air pump 32 can also be arranged on the cabinet door 11, so that the high-pressure air pump 32 and the jet component 31 can move synchronously with the opening and closing of the cabinet door 11, thereby reducing the complexity of the installation and connection of the two. Specifically, the high-pressure air pump 32 is connected to the jet component 31 through a plurality of connecting hoses 33, thereby providing a stable high-pressure air source for the jet component 31. Since the jet component 31 is movably arranged, the connecting hose 33 can be arranged in a spiral shape, thereby meeting the movement requirements of the jet component 31, ensuring that the length of the connecting hose 33 can meet the movement requirements of the jet component 31 during the movement of the jet component 31, thereby ensuring that the jet component 31 can be stably connected to the high-pressure air pump 32.

[0065] The positioning assembly 4 includes a first driving member arranged on the cabinet door 11, and the action end of the first driving member is connected to the jet member 31, thereby driving the jet member 31 to move; the first driving member can be a motor, and the action end of the motor is provided with a screw rod, and the stable movement of the jet member 31 is achieved through the cooperation of the ball screw. When the jet member 31 is a plurality of jet pipes, the jet pipes can be fixed on a frame having a carrier function, and the jet member 31 can be driven to move by opening a thread on the frame to cooperate with the screw rod.

[0066] When the jet component 31 is a box-shaped structure, for example, the jet component 31 includes an air guide box, the air guide box can be made of PVC (polyvinyl chloride). Since the air guide box itself has a certain frame structure, its own frame can be used as a carrier to be threadedly connected with the screw rod, thereby realizing the cooperation of the ball screw. The jet hole 34 is opened on the air guide box, but since the shape of the air guide box is relatively fixed, when the high-pressure gas in the connecting hose 33 enters the air guide box, the gas flow direction is not necessarily directly toward the jet hole 34, which may cause the air guide box to weaken the pressure of the high-pressure jet. Therefore, a flow channel of a certain shape can be set on the air guide box, so that the high-pressure gas can smoothly pass through the flow channel to the jet hole 34 to ensure that the jet pressure of the high-pressure gas will not be weakened.

[0067] It is pointed out above that the jet element 31 can have vertical movement, so the first driving element should be a vertical driving motor 41 arranged on the cabinet door 11, please refer to Figure 1 and Fig.10 The action end of the vertical drive motor 41 is arranged vertically, and a vertical drive screw 42 arranged vertically is connected to the action end of the vertical drive motor 41, and the vertical drive screw 42 is threadedly connected to the air guide box, thereby driving the air guide box to move vertically. At the same time, in order to ensure the movement stability of the air guide box, two sets of vertical drive motors 41 and vertical drive screws 42 can be arranged on both sides of the cabinet door 11, and linear guide columns, linear guide rails and other structures can also be added to limit the movement of the air guide box.

[0068] It is also pointed out above that the jet component 31 can have vertical and lateral movement, so the first driving component also includes a lateral driving motor, which can drive the jet component 31 to move horizontally. Specifically, the air guide box includes a box body and a frame, the jet hole 34 is arranged on the box body, and the corresponding flow channel can also be arranged on the box body, and the box body is movably arranged on the frame, and the frame serves as a bearing carrier of the box body. The first driving screw can be threadedly connected with the frame to form a ball screw, thereby driving the box body to move vertically; at the same time, the lateral driving motor is arranged on the frame, and the action end of the lateral driving motor is connected with a lateral driving screw arranged horizontally, and the lateral driving screw is threadedly connected with the box body, thereby driving the box body to move horizontally, so that the vertical and lateral movement of the jet component 31 can be realized. Of course, the box body can also be arranged on the frame through structures such as linear guide columns and linear guide rails to improve the movement stability of the box body.

[0069] It should be pointed out that, considering that the high-pressure gas ejected from the jet hole 34 has a relatively fixed jet angle when jetting into the gap of the heat sink 21, some stubborn dust cannot be completely removed if a fixed angle jet is used; therefore, the present invention can also enable the jet hole 34 to be dislocated relative to the gap between adjacent sheets by means of the lateral movement of the jet element 31, thereby changing the action position of the jet hole 34 by the dislocation effect, and further changing the angle at which the high-pressure gas ejected from the jet hole 34 enters the gap between adjacent sheets; specifically, when the jet hole 34 is directly opposite to the gap between adjacent sheets, the jet direction of the high-pressure gas is parallel to the gap between adjacent sheets, and the positioning component 4 drives the jet element 31 to move lateraly by a preset distance, so that the jet hole 34 is dislocated from the gap between adjacent sheets. At this time, the high-pressure gas will interfere with the heat sink 21 itself, thereby changing the angle at which the high-pressure gas enters the gap between adjacent sheets through interference, and further allowing the high-pressure gas to enter the gap between adjacent sheets at different angles, effectively cleaning the dust in the gap of the heat sink 21. In addition, the jet component 31 can also realize reciprocating lateral movement driven by the lateral drive motor. Within the range of repeated lateral movement, the jet component 31 can repeatedly change the angle at which the high-pressure gas enters the gap between adjacent sheets, further improving the cleaning effect of the high-pressure jet on the heat sink 21.

[0070] It should be pointed out that the first driving member can also use a hydraulic cylinder, a pneumatic cylinder, an electric cylinder or other power cylinder to drive the jet member 31, and no further restrictions are made here, and all fall within the protection scope of the present invention.

[0071] In some embodiments, the cabinet door 11 further includes a door frame rotatably connected to the cabinet body 1, and a filter core plate 12 is provided on the door frame. Figure 1 and Figure 2The filter core plate 12 can be used as a door plate of the cabinet door 11. The filter core plate 12 can be made of HEPA (high efficiency air filter) high efficiency filtering material, which can effectively filter dust particles in the air and extend the service life of the server.

[0072] In addition, please refer to Figure 4 A plurality of exhaust fans 13 are provided on the back side of the cabinet 1. The exhaust fans 13 can correspond to the positions of the storage components 2 respectively, and can quickly discharge the heat generated by the server when it is working, thereby improving the heat dissipation effect. At the same time, after the jet part 31 is started, the dust will be blown into the storage component 2, and the dust in the storage component 2 can also be quickly discharged through the exhaust fans 13.

[0073] The storage assembly 2 includes a storage frame 22, a slide 23, a push-out mechanism 26 and a locking mechanism 27. Figure 5 The storage frame 22 is provided with at least an opening in the same direction as the opening side of the cabinet 1, so that the server can be taken and placed through the opening. In order to allow the heat to be quickly discharged through the storage assembly 2, an opening can also be provided on the rear side of the storage frame 22, so that the heat and dust can be discharged through the rear opening of the storage frame 22. The storage frame 22 is a rectangular frame structure as a whole, which can effectively bear the weight. The slide 23 is installed on the bottom side of the storage frame 22, and can be correspondingly set to a rectangular plate structure, made of aluminum alloy, light in weight and easy to slide; the heat sink 21 is provided on the slide 23, and the server is placed in the space between the heat sink 21 and the top of the storage frame 22.

[0074] The ejection mechanism 26 is arranged on the bottom side of the storage frame 22, specifically between the slide 23 and the bottom plate of the storage frame 22. The ejection mechanism 26 includes a second driving member, and the action end of the second driving member is connected to the slide 23, thereby driving the slide 23 in and out of the storage frame 22. When replacing or upgrading the server, the maintenance operation can be completed without disassembling the cabinet, thereby reducing maintenance costs.

[0075] The locking mechanism 27 is arranged on the top side of the storage frame 22, and includes a third driving member. The action end of the third driving member is provided with a clamping plate 271. The clamping plates 271 are arranged on both sides of the server. Driven by the third driving member, the clamping plates 271 can be clamped on the side walls on both sides of the server, so that the server can be stably placed on the heat sink 21. Of course, the setting method of the locking mechanism 27 includes but is not limited to the form of the clamping plate 271, and components such as fastening bolts and limit pins can also be used to achieve the locking and positioning of the server to ensure a relatively stable locking effect. They will not be described in detail here, and all fall within the protection scope of this application.

[0076] To ensure the stable sliding effect of the slide 23, a supporting slide rail 24 is provided on the bottom side of the storage frame 22. The slide 23 is slidably connected to the storage frame 22 through the supporting slide rail 24. There are at least two groups of supporting slide rails 24, which can be correspondingly arranged on both sides of the slide 23. The supporting slide rails 24 can be made of stainless steel, which can effectively bear weight and reduce friction.

[0077] Please refer to Figure 8 The second driving member is a second driving motor 261. The action end of the second driving motor 261 is provided with a second driving screw 262. The outer periphery of the second driving screw 262 is provided with a second screw sleeve 263 that matches with it to form a ball screw structure. The second screw sleeve 263 can be supported by copper material, which can effectively reduce friction. The second screw sleeve 263 is fixedly connected to the slide 23. Specifically, the second screw sleeve 263 is a square block structure. The top tube wall of the square block is fixedly connected to the bottom tail end of the slide 23. The forward and reverse rotation of the second driving motor 261 drives the slide 23 to slide forward and backward, which is convenient for driving the server to be exported or imported into the storage frame 22.

[0078] A second slide groove is also provided on the inner bottom surface of the storage frame 22. The second slide groove is arranged in the same direction as the axial direction of the second driving screw 262. The second screw sleeve 263 is slidably arranged in the second slide groove. Specifically, the bottom tube wall and the side tube wall of the second screw sleeve 263 are limitedly abutted against the second slide groove, thereby limiting the second slide groove to move only along the axial direction of the second driving screw 262, avoiding the tendency of rotation, so as to improve the smoothness of the sliding process of the slide 23.

[0079] Please refer to Figure 7 The third driving member is a dual-axis reduction motor 272. The action ends of the dual-axis reduction motor 272 are provided with third driving screws 273. The outer periphery of the third driving screw 273 is sleeved with a third screw sleeve 274 that matches with it to form a ball screw structure. The clamping plate 271 is fixedly connected to the third screw sleeve 274, so that under the drive of the dual-axis reduction motor 272, the clamping plates 271 on both sides move toward or away from each other to clamp or release the server.

[0080] Similarly, a third slide groove 253 is also opened on the inner top surface of the storage frame 22. The third slide groove 253 and the third driving screw 273 are axially arranged in the same direction. The third screw sleeve 274 is slidably arranged in the third slide groove 253, and the outer wall of the third screw sleeve 274 is limitedly abutted against the third slide groove 253 to limit the third slide groove 253 to move only along the axial direction of the third driving screw 273. For details, please refer to the setting method and principle of the second screw sleeve 263 and the second slide groove.

[0081] Please refer to Figure 6 and Figure 7A top platform 25 is provided on the top surface of the storage frame 22. The top platform 25 is a rectangular plate-shaped structure server disposed in the space between the heat sink 21 and the top platform 25. The corresponding locking mechanism 27 can be provided on the top platform 25. A temperature sensor 252 for monitoring the working temperature of the server is provided on the side of the top platform 25 facing the server. A status display screen 251 is provided on the side of the top platform 25 facing the opening of the storage frame 22. The status display screen 251 is connected to the temperature sensor 252 by signal. The status display screen 251 can display the working status and temperature information of the server in real time, which is convenient for remote monitoring.

[0082] After the server has been used for a period of time, dust will gradually accumulate on the heat sink 21, resulting in reduced heat dissipation function of the heat sink 21. The present invention can set a fixed use time so that the jet component 31 can regularly clean the heat sink 21; specifically, when the preset time is reached, the jet component 3 is first started to spray high-pressure gas from the jet hole 34. At this time, the cabinet 1 is in a closed state, and the jet component 3 sprays the heat sink 21 at the initial position. After the preset jet time, the jet component 3 moves to the position of the next heat sink 21 under the drive of the positioning component 4, and sprays the heat sink 21 after reaching the specified position; repeat the above steps until the jet component 3 automatically resets to the initial position after the jet cleaning of each heat sink 21 is completed.

[0083] As to how to make the jet assembly 3 accurately reach the position corresponding to each heat sink 21, in some embodiments, the position control of the jet assembly 3 can be achieved by controlling the number of rotations of the motor or controlling the extension length of the power cylinder. Specifically, the first driving member is introduced by taking the motor as an example, that is, the horizontal driving motor and the vertical driving motor 41 can adopt a servo motor or a stepping motor, which has high control accuracy. The first driving member is controlled to rotate by the control unit, and according to the specific setting position of each heat sink 21, the horizontal and vertical displacements of the jet assembly 3 when it reaches another heat sink 21 from one heat sink 21 are calculated, and according to the pitch in the ball screw structure, the number of rotations of the screw rod when the ball reaches the above displacement is calculated, and the number of rotations of the screw rod is actually the number of rotations of the first driving member, and the number of rotations is written into the control unit in the form of a control program, so as to realize the automatic control of the jet member 31, and then realize that the jet member 31 can accurately reach the position of each heat sink 21.

[0084] For example, the jet component 31 corresponds to the position of a heat sink 21 at the initial position. If it needs to move 5cm in the horizontal direction and 10cm in the vertical direction to reach the next heat sink 21, the vertical drive screw 42 and the air guide box form a ball screw with a diameter of 20mm, and the screw pitch is 5mm. Then, for each rotation of the vertical drive motor 41, the air guide box will move 5mm vertically. If it needs to move 10cm vertically, the vertical drive motor 41 needs to rotate 20 times; similarly, if the ball screw pitch formed by the horizontal drive screw and the box body is also 5mm, it needs to rotate 10 times to move 5cm in the horizontal direction. Of course, the above values ​​are all examples, including but not limited to the parameters given above. The number of rotations of the motor can be selectively set according to the actual displacement and the pitch of the ball screw to achieve the purpose of accurately controlling the moving position of the jet component 31.

[0085] When the first driving member is a power cylinder such as a hydraulic cylinder or a pneumatic cylinder, its extension length can be controlled by controlling the flow of fluid entering the interior or a limit switch can be added to control the displacement of the jet member 31; when the first driving member is an electric cylinder, an electric cylinder with programmable control can be used to achieve high-precision control of the extension length, thereby controlling the displacement of the jet member 31.

[0086] In some embodiments, the temperature of each server can also be monitored in real time through the temperature sensor 252. By observing the temperature of the server, it is determined whether the heat sink 21 needs to be cleaned. When the server temperature exceeds the preset temperature, the reason for this phenomenon may be that the heat sink 21 is too much dust. At this time, according to the information displayed on the status display screen 251, the jet component 31 is controlled to reach the heat sink 21 corresponding to the specified server, and the heat sink 21 is jet-cleaned until the server temperature returns to a safe working temperature. If the server still exceeds the preset temperature after the jet component 31 continues to jet for a certain period of time, the server can be shut down for maintenance, or the frequency of server use can be reduced to eliminate safety hazards.

[0087] In addition, a camera device can be arranged inside the cabinet 1. The camera device can be arranged on the jet element 31 and move synchronously with it, or the camera device can be arranged on the storage frame 22 or the cabinet door 11, and it is ensured that the camera device can record the real-time image of each heat sink 21; the dust image on the heat sink 21 is obtained by the camera device, and the amount of dust is judged according to the dust image, wherein the camera device should try to record the real-time image in the gap of the heat sink 21, so as to judge the amount of dust. The camera device can also be connected to the control unit signal, and the control unit is connected to the position adjustment component 4 signal, so according to the amount of dust on the heat sink 21, the position adjustment component 4 can control the jet element 31 to stay longer in the place with more dust, and vice versa, if the amount of dust on the heat sink 21 is less, the position adjustment component 4 can selectively control the jet element 31 not to stay in the corresponding position or stay for a shorter time.

[0088] And after the jet cleaning of the jet part 31 is completed, the cleaning status of the heat sink 21 after the jet cleaning can be monitored in real time through the camera device, that is, whether the heat sink 21 is cleaned in place after the jet cleaning. If it is cleaned in place, the positioning component 4 is controlled to drive the jet part 31 to move to the next workstation; if it is not cleaned in place, the cleaning is continued until it is completely cleaned in place.

[0089] Secondly, if the camera device and the jet component 31 act synchronously under the adjustment of the positioning component 4, it is not necessary for the camera device and the jet component 31 to work at the same time, that is, the need for jet cleaning and the need for photography can be relatively independent. When it is necessary to observe the dust accumulation, the jet component 31 and the camera device can be controlled by the positioning component 4 to reach the specified position, the camera device observes the dust accumulation, and the jet component 31 can be selectively turned on after observing the dust accumulation. And because the jet component 31 can reach the position of any heat sink 21, the camera device can also reach the position of any heat sink 21 accordingly, so as to observe the dust accumulation on each heat sink 21 according to the needs.

[0090] Taking into account that the heat sink 21 itself has a certain length and the observation range of the camera device is limited, the use of a single camera device may not necessarily be able to fully observe the dust accumulation on the entire heat sink 21. Therefore, a ball screw structure similar to a transverse drive motor and a transverse drive screw may be separately provided on the jet component 31, so that the camera device can move laterally or in the length direction of the heat sink 21, and then observe the gap between any two adjacent sheets in the heat sink 21, so that the staff can make a more accurate judgment on the dust accumulation of the heat sink 21.

[0091] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
