[0026] When the heat exchange type or air conditioning type outdoor cabinet heat dissipation system has been in operation for a long time, there is a probability of failure. Since the heat exchange type or air conditioning type outdoor cabinet is an enclosed cabinet, after the heat dissipation system fails, the temperature inside the cabinet will rise rapidly and exceed the normal operating temperature of the equipment inside the cabinet, and the equipment inside the cabinet will operate abnormally. To address this problem, existing outdoor cabinets usually have emergency ventilation devices. However, when the existing emergency ventilation devices are not in operation, external dust and corrosives are likely to enter the cabinet interior through their air ducts, affecting the normal operation of the enclosed cabinet.

[0027] Analysis shows that the main reason for the above problem is that the air ducts of the existing emergency ventilation devices cannot be closed when they are not in operation. It can be considered to set a wind valve structure in the air ducts of the emergency ventilation devices and make the wind valve structure controllable to open and close automatically, which can alleviate the above problem.

[0028] In view of this, the embodiments of this application propose a heat dissipation module and a cabinet, aiming to alleviate the problem that when the emergency ventilation device of an existing enclosed cabinet is not in operation for heat dissipation, external dust and corrosives are likely to enter the cabinet interior through its air ducts, affecting the normal operation of the enclosed cabinet.

[0029] Please refer to Figure 1 、 Figure 2 and Figure 4, in some embodiments of the present application, the heat dissipation module 100 is used for the cabinet 1000. The cabinet 1000 has a heat dissipation cavity. The heat dissipation module 100 includes a housing 1, a fan 2 and a valve structure 3. The housing 1 forms an air duct 11. The air duct 11 has a first end 111 and a second end 112. The first end 111 of the air duct 11 is used to communicate with the heat dissipation cavity, and the second end 112 of the air duct 11 is used to communicate with the outside; the fan 2 is arranged in the air duct 11; the valve structure 3 is arranged in the air duct 11. The valve structure 3 has an opening and closing part 31 that can be movably arranged to be able to open and close the air duct 11.

[0030] It should be noted that in this embodiment, the fan 2 and the valve structure 3 are both arranged in the air duct 11 of the housing 1. There are at least two cases of the relative positions of the valve structure 3 and the fan. In the first case, the valve structure 3 is arranged near the first end 111 of the air duct 11, and the fan is arranged near the second end 112 of the air duct 11. In the second case, the valve structure 3 is arranged near the second end 112 of the air duct 11, and the fan is arranged near the first end 111 of the air duct 11. However, in either case, the valve structure 3 and the fan do not affect each other functionally; the function of the fan is to be able to ventilate, and the direction of its ventilation can be from the first end 111 to the second end 112, or from the second end 112 to the first end 111. This embodiment does not limit this; since the first end 111 of the air duct 11 communicates with the heat dissipation cavity of the cabinet 1000, and the second end 112 of the air duct 11 communicates with the outside, therefore, when the ventilation direction of the fan is from the first end 111 to the second end 112, the main function of the heat dissipation module 100 is to exhaust and dissipate heat from the heat dissipation cavity. When the ventilation direction of the fan is from the second end 112 to the first end 111, the main function of the heat dissipation module 100 is to supply air and cool the heat dissipation cavity.

[0031] The structural form of the opening and closing part 31 of the valve structure 3 includes at least two cases: flipping opening and closing and sliding opening and closing. The structural form of flipping opening and closing is easy to understand. The sliding opening and closing structure is similar to the aperture structure of a camera lens (the ventilation control principle of sliding opening and closing is the same as the light inlet control principle of a camera lens aperture). This embodiment does not limit the structural form of the opening and closing part 31, as long as it can open and close the air duct 11 within its own moving stroke.

[0032] The types of the fan 2 in the embodiments of the present application include but are not limited to axial fans 2 and turbine fans 2; the heat dissipation module 100 in the embodiments of the present application can be applied to emergency heat dissipation scenarios and can also be applied to other heat dissipation scenarios.

[0033] The technical solution provided in the present application can controllably open and close the air duct 11 by setting an air valve structure 3 in the air duct 11, thereby preventing external dust and corrosive substances from entering the heat dissipation cavity of the cabinet 1000 through the air duct 11 and affecting the normal operation of the cabinet 1000 when the heat dissipation module 100 is not in operation for heat dissipation; not only that, the heat dissipation module 100 provided in the present application can also be retrofitted and installed on old cabinets. It only requires opening an air vent on the old cabinet body and connecting the shell 1 of the heat dissipation module 100 to the air vent and installing it on the old cabinet, so as to give the old cabinet the functions of heat dissipation ventilation and dustproof closure.

[0034] The specific structure of the opening and closing portion 31 has various forms. For example, in one case, the cross-sectional shape of the air duct 11 is rectangular, the opening and closing portion 31 is integrally arranged, and its cross-sectional shape is adapted to the air duct 11 to be also arranged to be rectangular. The opening and closing portion 31 is rotated along the central axis of the two opposite sides of the rectangle to control the opening and closing of the air duct 11. However, in this case, the rotation radius of the opening and closing portion 31 is large, and a large rotation space is required in the air duct 11, which is not conducive to the arrangement of other components, such as the fan 2 and the air valve structure 3. In view of this, please refer to Figure 2 and Figure 4 In some embodiments, the opening and closing portion 31 includes a plurality of rotatably arranged opening and closing leaves.

[0035] It needs to be explained that the opening and closing portion 31 in the present embodiment includes a plurality of rotatably arranged opening and closing leaves, and the rotation axes of the plurality of opening and closing leaves usually extend in the same direction, which includes a first direction of "being arranged at an angle to the central axis of the air duct 11", and the plurality of opening and closing leaves are usually arranged in a second direction of "being arranged at an angle to the central axis of the air duct 11", and the plurality of opening and closing leaves can reach the closing plane of the air valve structure 3 within their respective rotation strokes, thereby cooperating with each other to close the air duct 11. It can be understood that the opening and closing portion 31 is a flip opening and closing structure, and the present embodiment does not limit the power source of the plurality of opening and closing leaves, and the power source may be manual or mechanical.

[0036] According to the above technical scheme, the opening and closing portion 31 can realize the opening and closing control of the air duct 11 through the rotation of multiple opening and closing leaves; at the same time, compared with the method of controlling the opening and closing of the air duct 11 by the overall rotation of the opening and closing portion 31, in this scheme, the rotation radius of a single opening and closing leaf is smaller. When the multiple opening and closing leaves are in the open state, the space occupied by the opening and closing portion 31 in the extension direction of the central axis of the air duct 11 can be reduced. In view of this, the shell 1 of the heat dissipation module 100 can shorten the setting length of the air duct 11, so that the heat dissipation module 100 can be arranged more compactly as a whole, reducing the installation space occupied by the heat dissipation module 100 on the cabinet 1000.

[0037] For further information, please refer to Figure 2In some embodiments, the air valve structure 3 includes a driving portion 32 and a transmission mechanism 33. The transmission mechanism 33 is connected between the driving portion 32 and a plurality of opening and closing leaves to drive the plurality of opening and closing leaves to rotate.

[0038] It should be explained that the driving part 32 in the present solution is an automatic driving structure, which can replace manual work to complete the automatic driving opening and closing operation of the opening and closing part 31. The function of the transmission mechanism 33 is to synchronously transmit the power of the driving part 32 to multiple opening and closing pages, so as to synchronously drive the multiple opening and closing pages to rotate through the driving part 32. The transmission mechanism 33 can directly transmit the power of the driving part 32 to each opening and closing page, or indirectly transmit the power of the driving part 32 to each opening and closing page; the driving part 32 can be a driving cylinder, and the transmission mechanism 33 can be a connecting rod transmission mechanism 33. This embodiment does not limit the specific structural form of the driving part 32 and the transmission mechanism 33.

[0039] According to the above technical solution, under the power transmission of the transmission mechanism 33, the driving unit 32 can automatically and synchronously drive the multiple opening and closing leaves to rotate, thereby automatically and accurately controlling the multiple opening and closing leaves to open and close the air duct 11. Compared with the efficiency of manual driving, this solution has higher driving efficiency through the driving unit 32 and the transmission mechanism 33.

[0040] Among them, regarding the way in which the driving part 32 directly drives the multiple opening and closing pages to rotate through the transmission mechanism 33, for example, the driving part includes a driving belt, the transmission mechanism 33 includes a plurality of pulleys, the plurality of pulleys are connected to the ends of the plurality of opening and closing pages one by one, the driving belt is wound around the plurality of pulleys, and the plurality of pulleys can rotate synchronously under the drive of the driving belt.

[0041] For details, please continue to see Figure 2 In some embodiments, the transmission mechanism 33 includes a plurality of transmission gears 331, which are connected to the ends of the plurality of hinges one by one, and two adjacent transmission gears 331 are meshed; the driving unit 32 includes a driving motor, which is drivingly connected to one of the transmission gears 331.

[0042] It needs to be explained that in the present embodiment, multiple transmission gears 331 are respectively connected to the ends of the opening and hinge pages, which can be specifically understood as being arranged at the ends of the rotating shafts of the opening and hinge pages, and two adjacent transmission gears 331 are meshingly arranged, so the rotation of one of the transmission gears 331 can also drive all the transmission gears 331 to rotate, and the synchronous driving of multiple opening and hinge pages can be achieved by connecting the drive motor to one of the transmission gears 331. The specific drive connection method can be to directly connect the output shaft of the drive motor to the connecting hole of one of the transmission gears 331, or other indirect drive methods can be used to connect the transmission gears 331.

[0043] According to the above technical solution, the method of synchronous transmission through the meshing of multiple transmission gears 331 is more suitable for the scenario of opening and closing in cooperation with multiple hinge leaves. In principle, the diameter of the transmission gear 331 is equivalent to the width of the hinge leaf. Therefore, the transmission mechanism 33 composed of multiple meshing transmission gears 331 only occupies less installation space at the end of the hinge leaf, ensuring that the maximum air duct 11 space can be released after multiple hinge leaves are opened; moreover, since the rotation of adjacent two hinge leaves is controlled by the meshing transmission gears 331, the rotation directions of adjacent two hinge leaves are opposite, which prevents adjacent two hinge leaves from rubbing and wearing due to opposite-direction movements during the opening or closing process.

[0044] When the ventilation direction of the fan is from the second end 112 towards the first end 111, the function of the heat dissipation module 100 is to send air into the heat dissipation cavity of the cabinet 1000 for cooling. During this process, the air with dust and impurities from the outside will enter the heat dissipation cavity, and usually, there are some heating electrical components in the heat dissipation cavity. The dust and impurities are likely to adhere to the surface of the heating electrical components, which will affect the heat dissipation of the heating electrical components on the one hand and may cause short circuits of the heating electrical components on the other hand. In view of this, please refer to Figure 2 and Figure 4 , in some embodiments, a dust-proof structure 4 is further provided in the air duct 11.

[0045] It should be noted that the dust-proof structure 4 in this solution is arranged in the air duct 11, and its main function is to intercept dust impurities and corrosive pollutants in the passing air flow. The specific structure of the dust-proof structure 4 in this application embodiment is not limited, as long as it has the function of dust removal and filtration.

[0046] According to the above technical solution, by arranging the dust-proof structure 4 in the air duct 11, the dust impurities introduced into the suction air duct 11 can be intercepted and filtered, so as to ensure that the air flow introduced into the heat dissipation cavity of the cabinet 1000 remains clean, which is beneficial to maintaining the stable working state of the heating electrical components in the heat dissipation cavity and can also prevent the air duct 11 from being blocked.

[0047] Please continue to refer to Figure 4 , in some embodiments, the fan 2 is at least used to drive the air flow to enter from the second end 112 of the air duct 11 and output from the first end 111 of the air duct 11; the air valve structure 3 is located on the side of the dust-proof structure 4 close to the second end 112 of the air duct 11, and / or, the fan 2 is located on the side of the dust-proof structure 4 close to the first end 111 of the air duct 11.

[0048] It should be noted that since "the fan 2 is at least used to drive the air flow to enter from the second end 112 of the air duct 11 and output from the first end 111 of the air duct 11", therefore, the heat dissipation module 100 in this solution at least has the function of sending air into the heat dissipation cavity to cool it down; the above technical solution includes two parallel technical features, namely, "the air valve structure 3 is located on the side of the dust-proof structure 4 close to the second end 112 of the air duct 11" and "the fan 2 is located on the side of the dust-proof structure 4 close to the first end 111", and either one can be set, or both can be set simultaneously.

[0049] According to the above technical solution, the heat dissipation module 100 at least has the function of sending air into the heat dissipation cavity to cool it down. When the air valve structure 3 is arranged on the side of the dust-proof structure 4 close to the second end 112 of the air duct 11, when the air valve structure 3 is closed, it can cut off the air contact between the dust-proof structure 4 and the outside world, prevent the dust and impurities in the outside air from continuously polluting the dust-proof structure 4 when the heat dissipation module 100 is not working, and can extend the effective service life of the dust-proof structure 4; moreover, since the fan 2 is located on the side of the dust-proof structure 4 close to the first end 111, the air flow entering the air duct 11 reaches the fan 2 only after being filtered and cleaned by the dust-proof structure 4, which alleviates the situation of dust accumulation on the fan 2.

[0050] It can be understood that if the fan 2 can only ventilate unidirectionally, then a single heat dissipation module 100 only has a single exhaust or air supply function. When installing the heat dissipation module 100 on the cabinet 1000, it is necessary to ensure the installation directions of the first end 111 and the second end 112 of the air duct 11. When the installation direction is incorrect, it is also necessary to disassemble and reinstall the entire heat dissipation module 100, which will undoubtedly increase the installation difficulty of the heat dissipation module 100. In view of this, in some embodiments, the fan 2 is set as a fan 2 with bidirectional air output.

[0051] It should be noted that for the fan 2 with bidirectional air output, the switching of its air output direction can be realized electronically, and this embodiment will not elaborate on this.

[0052] According to the above technical solution, by setting the fan 2 as a fan 2 with bidirectional air output, its air output direction can be changed electronically. Based on this, when installing the heat dissipation module 100, there is no need to consider the reverse direction of the air duct 11 in its housing 1. Both the first end 111 and the second end 112 can be connected to the heat dissipation cavity, and only the air output direction of the fan 2 with bidirectional air output needs to be set after the installation is completed.

[0053] Combined with some embodiments, a dust-proof structure 4 is provided in the air duct 11. After a long period of filtering and dust removal, a large amount of dust and impurities will accumulate on the dust-proof structure 4, which may block the air duct 11. At this time, it needs to be cleaned manually, which undoubtedly increases the manual workload. In view of this, in some embodiments, the fan 2 is set as a fan 2 with bidirectional air output.

[0054] According to the above technical solution, the blower 2 is set as a blower 2 with bidirectional air outlet, and its air outlet direction can be changed electronically. Based on this, after a large amount of dust and impurities accumulate and are filtered by the dust-proof structure 4, by controlling the blower 2 to change the air outlet direction, the dust and impurities on the dust-proof structure 4 can be blown out to a certain extent, thereby achieving the purpose of cleaning the dust-proof structure 4 and reducing the frequency of manual cleaning.

[0055] In some embodiments, the dust-proof structure 4 is detachably connected to the housing 1.

[0056] It should be noted that there are many ways of detachable connection, such as snap connection, threaded connection or limit connection (limited in the ventilation direction of the air duct 11 and movable in the radial direction of the air duct 11). The detachable connection method in this embodiment is not limited.

[0057] According to the above technical solution, the dust-proof structure 4 is set to be detachably connected to the housing 1. After the dust-proof structure 4 is saturated with dust absorption, it can be detached from the air duct 11 for cleaning or replacement, preventing the air duct 11 from being blocked and ensuring the ventilation volume.

[0058] Furthermore, in some embodiments, an installation socket communicating with the air duct 11 is formed on the side wall of the air duct 11; the dust-proof structure 4 is inserted into the installation socket.

[0059] It needs to be explained that the function of the installation socket is to provide a place for the dust-proof structure 4 to be inserted. Its specific shape is adapted to the shape of the dust-proof structure 4. After the dust-proof structure 4 is installed in the installation socket, the dust-proof structure 4 and the housing 1 can also be connected by means of threaded connection as an auxiliary.

[0060] According to the above technical solution, through the setting of the installation socket, the dust-proof structure 4 can extend into the air duct 11 of the housing 1 through the installation socket to filter the air flow in the air duct 11. Since the installation socket is opened on the side wall of the air duct 11, the installation socket also has a limiting effect on the dust-proof structure 4 in the ventilation direction, and can stably maintain the position of the dust-proof structure 4 during ventilation; when the dust-proof structure 4 needs to be cleaned and replaced, only the dust-proof structure 4 needs to be pulled out from the side wall of the housing 1 and a clean dust-proof structure 4 is inserted. This installation and disassembly method is simple and efficient.

[0061] It should be noted that the blower 2 generally belongs to a standard component and can be directly purchased according to the design requirements. However, the blower 2 in this heat dissipation module 100 also needs to be installed on the housing 1 and is located in the air duct 11. Therefore, the structure of the blower 2 needs to be improved to increase its connection basis with the housing 1. However, it is conceivable that directly connecting the blower 2 and the housing 1 in the air duct 11 is usually difficult. Therefore, please refer to Figures 2 to 4, in some embodiments, the heat dissipation module 100 further includes a mounting panel 5. The mounting panel 5 is detachably mounted on the housing 1 and is provided at the first end 111 of the air duct 11 for covering. The mounting panel 5 is provided with air passing holes 51 corresponding to the air duct 11; the fan 2 is mounted on the side of the mounting panel 5 facing the air duct 11.

[0062] It should be noted that the mounting panel 5 in this solution serves as the connection foundation between the fan 2 and the housing 1. It is not difficult to understand that the mounting position of the fan 2 on the mounting panel 5 corresponds to its air passing holes 51; there are at least two cases for the way the mounting panel 5 covers the first end 111 of the air duct 11. First, a limiting step is formed at the opening of the first end 111 of the air duct 11, and the mounting panel 5 is erected on the limiting step to cover the first end 111. Second, the mounting panel 5 is directly covered on the housing 1 at the position corresponding to the first end 111 of the air duct 11. In either case, since the fan 2 is mounted on the inner side of the mounting panel 5, the fan 2 can be kept in the air duct 11.

[0063] According to the above technical solution, the fan 2 is transferred to the housing 1 through the mounting panel 5 without making structural changes to the fan 2. And since the mounting panel 5 covers the first end 111 of the air duct 11, the mounting panel 5 can be conveniently installed from the outside of the air duct 11, reducing the installation difficulty of the fan 2; moreover, due to the setting of the air passing holes 51 on the mounting panel 5, the ventilation volume of the air duct 11 can also be ensured.

[0064] Further, please refer to Figure 3 , in some embodiments, the heat dissipation module 100 further includes a control board 6. The control board 6 is provided in the housing 1 and is electrically connected to the fan 2 and the air valve structure 3. A power interface 61 and a signal interface 62 are provided on the control board 6; the control board 6 is mounted on the mounting panel 5.

[0065] It should be noted that the power interface 61 of the control board 6 is used to connect to an external power source or the power supply line of the cabinet 1000 to supply electrical energy to the fan 2 and the air valve structure 3, while the function of the signal interface 62 is to feedback start signals and stop signals to the control board 6, so as to drive the control board 6 to perform corresponding action controls on the air valve structure 3 and the fan 2. The sources of the start signals and stop signals can usually be temperature sensors provided in the heat dissipation cavity of the cabinet 1000 or can also be manually input.

[0066] According to the above technical solution, by arranging the control board 6 on the housing 1, it can directly transfer power supply for the fan 2 and the air valve structure 3, and can also control the fan 2 and the air valve structure 3 to perform corresponding start-stop actions after receiving a control signal. This enables the heat dissipation module 100 to be modularly and integrally installed in the cabinet 1000, and it only needs to connect the power supply and the signal line to enter the working state. On the one hand, it is beneficial to the installation of the heat dissipation module 100, and on the other hand, it can improve the old cabinet 1000 based on the heat dissipation module 100 to extend the service life of the old cabinet 1000.

[0067] In a specific embodiment, the heat dissipation module 100 includes a housing 1, a fan 2, a dust-proof structure 4 and an air valve structure 3. The housing 1 forms an air duct 11, and the air duct 11 has a first end 111 and a second end 112. The first end 111 of the air duct 11 is used to communicate with the heat dissipation cavity, and the second end 112 of the air duct 11 is used to communicate with the outside; the fan 2, the dust-proof structure 4 and the air valve structure 3 are all arranged in the air duct 11. In the direction where the air duct 11 extends from the second end 112 to the first end 111, the air valve structure 3, the dust-proof structure 4 and the fan 2 are arranged in sequence; wherein, the air valve structure 3 has a movable opening and closing part 31 to be able to open and close the air duct 11; the dust-proof structure 4 can be removed from the housing 1 through an installation socket formed on the housing 1; the fan 2 is set as a fan 2 with bidirectional air output.

[0068] Please refer to Figure 1 , this application embodiment also proposes a cabinet 1000, which includes a cabinet 1000 body and a heat dissipation module 100. The specific structure of the heat dissipation module 100 refers to the above embodiment. Since this cabinet 1000 adopts all the technical solutions of the above all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated one by one here. Among them, the cabinet 1000 body has a heat dissipation cavity, and the housing 1 of the heat dissipation module 100 forms an air duct 11, and the first end 111 of the air duct 11 communicates with the heat dissipation cavity.

[0069] In some embodiments, the cabinet 1000 includes but is not limited to an enclosed outdoor cabinet, and can also be other cabinets 1000 that require emergency heat dissipation functions, and even can be any non-enclosed cabinet 1000 that requires heat dissipation.

[0070] Further, please refer to Figure 1 , in some embodiments, a plurality of heat dissipation modules 100 are provided. The air outlet direction of the air duct 11 of one heat dissipation module 100 is from the first end 111 to the second end 112 of the air duct 11, and the air outlet direction of another heat dissipation module 100 is from the second end 112 to the first end 111 of the air duct 11.

[0071] It needs to be explained that, according to the above scheme, the heat dissipation modules 100 are arranged in plurality, and the number is at least two or more. The air outlet direction of one of the heat dissipation modules 100 is from the first end 111 of the air duct 11 to the second end 112. It can be understood that the function of the heat dissipation module 100 is to exhaust air from the heat dissipation cavity. The air outlet direction of another heat dissipation module 100 is from the second end 112 of the air duct 11 to the first end 111. It can be understood that the function of the heat dissipation module 100 is to ventilate the heat dissipation cavity. As for whether there are other heat dissipation modules 100 or whether other heat dissipation modules 100 are ventilating or exhausting, this embodiment does not limit this.

[0072] According to the above technical solution, cooling air is introduced into the heat dissipation cavity of the cabinet 1000 through a heat dissipation module 100, and hot air is discharged from the heat dissipation cavity of the cabinet 1000 by another heat dissipation module 100, thereby forming a gas reflux, thereby continuously taking away the heat generated by the heat-generating electrical components in the heat dissipation cavity, thereby improving the heat dissipation efficiency of the cabinet 1000.

[0073] In some embodiments, a temperature sensor is provided in the heat dissipation cavity, and the heat dissipation module 100 also includes a control board 6, which is electrically connected to the fan 2, the air valve structure 3, and the temperature sensor to control the operation of the fan 2 and / or the air valve structure 3 according to the temperature parameters detected by the temperature sensor.

[0074] It should be noted that the temperature sensor is arranged in the heat dissipation cavity, which can measure the overall temperature parameters in the heat dissipation cavity and feed back the overall temperature signal to the control board 6, and then the control board 6 decides whether to control the fan 2 and the air valve structure 3 to work. Generally speaking, a temperature threshold is set for the heat dissipation cavity of the cabinet 1000. When the overall temperature measured by the temperature sensor exceeds the temperature threshold, the fan 2 and the air valve structure 3 need to be controlled to work. When the overall temperature is lower than the temperature threshold again, the fan 2 and the air valve structure 3 can be controlled to stop working; please refer to Figure 4 The control board 6 is usually provided with a fan interface 63 corresponding to the fan 2 and a wind valve interface 64 corresponding to the wind valve structure 3, and the fan 2, the wind valve structure 3 and the control board 6 are connected through the fan interface 63 and the wind valve interface 64; generally speaking, the control board 6 can also control the fan 2 to rotate at a corresponding speed according to different temperature parameters fed back by the temperature sensor, so as to accurately regulate the temperature in the heat dissipation chamber.

[0075] In some embodiments, the cabinet 1000 body is provided with a communication module, and the heat dissipation module 100 also includes a control board 6, which is electrically connected to the fan 2, the air valve structure 3, and the communication module to control the operation of the fan 2 and / or the air valve structure 3 according to the control instructions received by the communication module.

[0076] It should be noted that the communication module can at least obtain the specific temperatures of the electrical components in the heat dissipation cavity. Different electrical components usually have their own temperature thresholds. When the communication module obtains that the specific temperatures of some of the electrical components exceed their own temperature thresholds, the communication module can feedback a control instruction to the control board 6, thereby controlling the fan 2 and the air valve structure 3 to work. Moreover, the communication module can also receive a control instruction input manually and feedback the control instruction to the control board 6, thereby actively controlling the fan 2 and the air valve structure 3 to work under the interference of the human.

[0077] It should be noted that for the above two parallel technical solutions, namely "a temperature sensor is arranged in the heat dissipation cavity, and the heat dissipation module 100 further includes a control board 6. The control board 6 is electrically connected to the fan 2, the air valve structure 3, and the temperature sensor to control the fan 2 and / or the air valve structure 3 to work according to the temperature parameters detected by the temperature sensor" and "a communication module is arranged on the cabinet 1000 body, and the heat dissipation module 100 further includes a control board 6. The control board 6 is electrically connected to the fan 2, the air valve structure 3, and the communication module to control the fan 2 and / or the air valve structure 3 to work according to the control instruction received by the communication module", either one can be set, or both can be set simultaneously. Obviously, the effect of setting both simultaneously is better.

[0078] According to the above technical solution, through the setting of the temperature sensor, the overall temperature in the heat dissipation cavity of the cabinet 1000 can be directly and real-time fed back to the heat dissipation plate of the heat dissipation module 100, so that the fan 2 and the air valve structure 3 can be controlled by the control board 6 to work spontaneously, and the heat dissipation cavity can be cooled in time to prevent the aging and damage of the electrical components in the cabinet 1000 due to untimely heat dissipation. Through the setting of the communication module, the specific temperatures of the electrical components in the heat dissipation cavity can be obtained in real time, and when the specific temperature exceeds the temperature threshold of the electrical component, a control instruction is fed back to the control board 6, or the externally input control instruction is directly fed back to the control board 6, so that the fan 2 and the air valve structure 3 are controlled by the control board 6 to work, and the heat dissipation cavity is cooled in time. The temperature sensor and the communication module work together to make up for the limitations of representing the overall temperature and the specific temperature of the electrical components in the heat dissipation cavity, so as to correctly and efficiently realize the heat dissipation of the cabinet 1000.

[0079] The basic control logic of the heat dissipation module in this embodiment is as follows:

[0080] When the temperature parameter fed back by the temperature sensor to the control board 6 is greater than the temperature threshold, or when the communication module inputs a control instruction to the control board, the control board 6 generates a start signal and controls the air valve structure 3 and the fan 2 to start;

[0081] When the temperature parameter fed back by the temperature sensor to the control board 5 is less than the temperature threshold, and when the communication module stops inputting a control instruction to the control board 5, the control board 5 generates a stop signal and controls the air valve structure 3 and the fan 2 to start;

[0082] If the air valve structure 3 or the fan 2 is not turned on within the preset time after the control board 6 generates a start signal, an alarm signal is uploaded.

[0083] The above are only exemplary embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structural transformation made under the technical concept of the present application by using the content of the specification and drawings of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
