Technical Field

[0001] This application relates to the field of measurement and control equipment, and more particularly to a heat dissipation component and measurement and control equipment. Background Technology

[0002] Automatic measurement and control equipment refers to a system that connects various instruments and equipment (such as controllers, measuring instruments, and recording instruments) in a certain way to complete automatic measurement and control tasks. Automatic testing, in particular, changes the traditional manual measurement, recording, and processing methods, making the entire measurement process completely computer-controlled. It uses various instruments and equipment to automatically measure different measured objects, automatically process data, and automatically display and print the results. The main components of an automatic measurement and control system include: sensors, controllers, signal processing, transmission devices, and display devices. Automatic measurement and control equipment is widely used in the aviation, aerospace, railway, and automotive manufacturing industries, and represents a relatively mature technology. However, currently available automatic measurement and control equipment, while meeting salt spray resistance and electromagnetic compatibility requirements, cannot simultaneously provide both air cooling and liquid cooling for dual-mode heat dissipation. Summary of the Invention

[0003] The purpose of this application is to provide a heat dissipation component and measurement and control equipment that, while meeting the requirements of salt spray resistance and electromagnetic compatibility, also has dual-mode heat dissipation capabilities of air cooling and liquid cooling to adapt to the heat dissipation needs of different measurement environments.

[0004] Therefore, in a first aspect, embodiments of this application provide a heat dissipation assembly for a measurement and control device, the measurement and control device including a housing with a cavity, the cavity containing a heat-generating element, the heat dissipation assembly including:

[0005] A first heat dissipation component is disposed in the accommodating cavity. The first heat dissipation component includes a housing and a liquid cooling heat dissipation section. The housing has an accommodating space for placing the heat-generating component. The liquid cooling heat dissipation section is arranged on the side wall of the housing.

[0006] The second heat dissipation component includes a fan and a heat-conducting part. The heat-conducting part is in contact with the housing.

The air inlet is located near the heat-conducting part, and the air outlet is correspondingly disposed with the fan.

[0007] In one possible implementation, at least one sidewall of the housing has a plurality of slots arranged at intervals on its inner wall, the slots being used to restrict the movement of the heat-generating element, and the liquid cooling heat dissipation section is disposed on the sidewall with the slots arranged.

[0008] In one possible implementation, along the height direction of the housing, the shell has opposing first and second sidewalls.

[0009] Along the first direction, the inner walls of the first sidewall and the inner walls of the second sidewall are respectively provided with the plurality of slots arranged at intervals. The slots extend along the second direction, the first direction and the second direction intersect, the first direction and the height direction intersect, and the liquid cooling heat dissipation part is disposed on the first sidewall and the second sidewall.

[0010] In one possible implementation, the liquid cooling heat dissipation unit is a circulation pipeline disposed in the housing, the circulation pipeline having an inlet pipe and an outlet pipe, the inlet pipe and the outlet pipe passing through the housing and connecting to an external device.

[0011] The circulation pipeline includes a plurality of first pipeline segments arranged along the first direction on the first sidewall and the second sidewall. The first pipeline segments extend along the second direction, and adjacent first pipeline segments are connected by second pipeline segments to connect the pipeline segments located on the first sidewall and the second sidewall to form the circulation pipeline. The first pipeline segments located on the corresponding sidewalls are respectively provided for the slots.

[0012] In one possible implementation, the heating element includes a controller, and when the controller is disposed in the slot, at least the inner wall of the first conduit segment opposite to the controller is provided with a plurality of spaced protrusions.

[0013] In one possible implementation, the first sidewall and the second sidewall are respectively provided with recesses corresponding to the circulation pipeline. The first sidewall is provided with a first cover plate, and the second sidewall is provided with a second cover plate. The first cover plate and the second cover plate are respectively used to cover the corresponding recesses, so that the first sidewall and the first cover plate, and the second sidewall and the second cover plate together enclose and form a connected flow channel, which serves as the circulation pipeline.

[0014] In one possible implementation, the heat-conducting part is attached to the outer surface of the second sidewall, and the heat-conducting part is a heat sink.

[0015] The air inlet is located on the bottom plate of the housing, and the air outlet is located on the rear plate of the housing.

[0017] The air guide plate has an arc-shaped surface, which is used to guide the air from the second air duct to the air outlet.

[0018] In one possible implementation, the housing has an opening to connect the accommodating cavity and the accommodating space to form a sealed space, the opening facing the rear plate, and the air guide plate is used to separate the heat dissipation air duct from the sealed space.

[0020] According to the heat dissipation assembly and measurement and control equipment provided in the embodiments of this application, based on the housing, a separate shell is set inside the housing's accommodating cavity. Heat-generating components used for measurement and control are housed within the shell, allowing the heat-generating components to be placed in a sealed space to meet electromagnetic compatibility requirements. Simultaneously, a first heat dissipation component arranged around the periphery of the shell enables water cooling of the heat-generating components within the sealed space. Furthermore, the heat dissipation airflow formed by the enclosure between the shell and the housing enables air cooling of the heat transferred from the heat-generating components to the shell. Through separate and combined water and air cooling, multiple heat-generating components can achieve optimal heat dissipation under different operating conditions. Moreover, it meets the environmental requirements for salt spray resistance during measurement and control, ensuring good heat dissipation performance while ensuring that the internally housed heat-generating components are enclosed within the accommodating space, thus improving measurement and control performance.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] Figure 1 The diagram shows a structural schematic of a measurement and control device provided in an embodiment of this application, wherein the arrow points in the direction of the height of the housing. Figure 2 This is a schematic diagram of the structure of a measurement and control device in the open state according to an embodiment of this application. Figure 3 An exploded view of a measurement and control device provided in an embodiment of this application is shown. Figure 4 This is a cross-sectional view of a measurement and control device provided in an embodiment of this application.

[0035] See Figures 1 to 4 This application provides a heat dissipation component for use in measurement and control equipment. Measurement and control equipment refers to equipment that connects various instruments and devices (such as controllers, measuring instruments, recording instruments, etc.) in a certain way to complete automatic measurement and control tasks. The measurement and control equipment includes a housing 1 with a cavity 17, within which a heat-generating component 4 is provided. The heat-generating component 4 (for example, it can be an integrated chip that generates heat, such as a sensor, controller, or signal processor in the measurement and control equipment) can be set according to the specific functions implemented by the measurement and control equipment; no specific limitation is made here. It is understood that the heat dissipation component can also be set in other equipment with high heat dissipation requirements; no specific limitation is made here. The following detailed description uses the application of the heat dissipation component in measurement and control equipment as an example.

[0036] The heat dissipation assembly includes a first heat sink 3 and a second heat sink 2. The first heat sink 3 is disposed in the accommodating cavity 17 and includes a housing 32 and a liquid cooling heat dissipation section 33. The housing 32 has an accommodating space 31 for placing the heat-generating component 4. The liquid cooling heat dissipation section 33 is arranged on the side wall of the housing 32. The second heat sink 2 includes a fan 23 and a heat-conducting section 21. The heat-conducting section 21 is in contact with the housing 32. The housing 32, the heat-conducting section 21, and the enclosure 1 enclose a heat dissipation duct 19. The heat dissipation duct 19 has an air inlet 121 and an air outlet 131 disposed in the enclosure 1. The air inlet 121 is located near the heat-conducting section 21, and the air outlet 131 is correspondingly provided with the fan 23. Based on the enclosure 1, a separate shell 32 is installed inside the accommodating cavity 17 of the enclosure 1. A heat-generating element 4 for measurement and control is installed inside the shell 32. This allows the heat-generating element 4 to be housed in a sealed space to meet electromagnetic compatibility requirements. Liquid cooling heat dissipation units 33 arranged around the periphery of the shell 32 provide water cooling for the heat-generating element 4 within the sealed space. Simultaneously, the heat dissipation airflow 19 formed between the shell 32 and the enclosure 1 provides air cooling for the heat transferred from the heat-generating element 4 to the shell 32. By combining water cooling and air cooling individually and in combination, optimal heat dissipation is ensured when the heat-generating element 4 is combined under different heat dissipation conditions. Furthermore, it meets the environmental requirements for salt spray resistance during measurement and control, ensuring good heat dissipation performance while ensuring that the heat-generating element 4 is enclosed within the accommodating space 31, thus improving measurement and control performance.

[0037] Optionally, the housing 1 and shell 32 can be designed with different shapes and sizes according to requirements, and the accommodating cavity 17 and accommodating space 31 formed therein can also be set with corresponding shapes, which are not specifically limited here. In the embodiments of this application, both the housing 1 and shell 32 are hexahedral square structures, which will not be emphasized separately thereafter.

[0038] The enclosure 1 includes a bottom plate 12 and a top plate 11, a front plate 14 and a rear plate 13, and a left plate 15 and a right plate 16. Except for the front plate 14, the other plates can be fixedly connected. The front plate 14 can move relative to each other to form the enclosure 1, so that when the front plate 14 is opened, the corresponding heat dissipation components, heat-generating components 4, etc. can be easily placed in and electrically connected. When the front plate 14 is closed, a closed accommodating cavity 17 is formed.

[0039] Optionally, the front panel 14 is rotatably connected to the housing 1 via a pivot assembly 142 to facilitate opening or closing. The features and connection relationships of the pivot assembly 142 and the specific components corresponding to the opening and closing operations are not described in detail here.

[0040] In addition, the front panel 14 may also be equipped with a handle 141 for opening and closing, a lock-on screw, etc., which will not be described in detail here. Furthermore, the front panel 14 may also be equipped with an interface device 143 such as a USB port for electrical connection with the internal heating element 4.

[0041] Optionally, when the plates are connected to form the housing 1, a sealing groove is provided on the circumferential edge of each plate to accommodate the sealing ring, so that the formed housing 1 has a better sealing effect. The sealing ring adopts a double-peak shielding strip 18, and the enclosed cavity 17 is a sealed space used to shield the heat-generating component 4, so as to meet the electromagnetic compatibility requirements and prevent salt spray. The specific sealing mating structure is not described in detail here.

[0042] It should be emphasized that the casing 1 is made of high-strength hard aluminum welded together.

[0043] In an alternative embodiment, see Figure 5 At least one side wall of the housing 32 has a plurality of slots 311 arranged at intervals on its inner wall. The slots 311 are used to restrict the movement of the heat-generating element 4, and the liquid cooling heat dissipation unit 33 is disposed on the side wall with the slots 311. When the heat-generating element 4 is placed in the accommodating space 31, in order to ensure the stability of the heat-generating element 4 within it and to avoid damage to the heat-generating element 4 due to shaking caused by force, the heat-generating element 4 can be detachably connected to the slots 311. The liquid cooling heat dissipation unit 33 is disposed on the side wall with the slots 311 to ensure a better water cooling heat dissipation effect and achieve better heat dissipation for the heat-generating element 4.

[0044] It is understandable that the size of the multiple slots 311 and the spacing between adjacent slots 311 are set according to the specific size and dimensions of the heating element 4 being fixed, and no specific limitation is made here. Alternatively, the size of the slots 311 can be set uniformly, and the heating element 4 can be provided with protrusions that mate with the slots 311, so that when the heating element 4 is inserted into the corresponding slot 311, it only needs to be mated with the protrusions. Alternatively, a locking or sliding mechanism can also be used, which will not be described in detail here.

[0045] Optionally, the slots 311 can be provided on the inner wall of only one side wall of the housing 32, or on the inner walls of two opposite side walls of the housing 32, or three, four, etc. It can also be understood that the heat-generating element 4 is in direct contact with one or more side walls of the housing 32, and no specific limitation is made here. The first heat sink 3 of this application will be described in detail below with the example of providing slots 311 on two opposite side walls.

[0046] See Figures 5 to 7The plane formed by the first direction X and the second direction Y is a horizontal plane. The box 1 is placed horizontally on the horizontal plane. The first direction X and the second direction Y are perpendicular. The height direction H of the box 1 is perpendicular to the first direction X. This will not be emphasized separately later.

[0047] Along the height direction H of the housing 1, the shell 32 has opposing first sidewalls 321 and second sidewalls 322. The first sidewall 321 faces the top plate 11 of the housing 1, and the second sidewall 322 faces the bottom plate 12 of the housing 1. Along the first direction X, the inner walls of the first sidewall 321 and the second sidewall 322 are respectively provided with a plurality of slots 311 arranged at intervals. The slots 311 extend along the second direction Y. The first direction X and the second direction Y intersect. The first direction X intersects with the height direction H. The liquid cooling heat dissipation part 33 is disposed on the first sidewall 321 and the second sidewall 322. For the shell 32, the temperature rise near the slots 311 that directly contact and cooperate with the heat-generating element 4 is significantly higher than other locations. Therefore, placing the liquid cooling heat dissipation part 33 on the first sidewall 321 and the second sidewall 322, where the temperature rise is significant, can better perform water cooling heat dissipation and improve the heat dissipation effect.

[0048] In an optional embodiment, the liquid cooling heat dissipation unit 33 is a circulation pipeline disposed on the housing 32. The circulation pipeline has an inlet pipe 34 and an outlet pipe 35, which pass through the housing 1 and connect to an external device. The circulation pipeline is respectively arranged on the first side wall 321 and the second side wall 322, and the pipelines located in the two side walls are connected as one unit. In order to increase the effective heat dissipation area, the circulation pipeline is arranged in an S-shape on the corresponding side walls. As for the inlet pipe 34 and the outlet pipe 35, it is sufficient to ensure that they pass through the housing 1 and connect to the external cooling device. Preferably, the inlet pipe 34 and the outlet pipe 35 pass through the rear plate 13 of the housing 1 side by side to avoid affecting the arrangement of other internal components.

[0049] Specifically, the circulation pipeline includes multiple first pipeline segments 36 arranged along the first direction X on the first sidewall 321 and the second sidewall 322. The first pipeline segments 36 extend along the second direction Y. Adjacent first pipeline segments 36 are connected through second pipeline segments 37 to connect the pipeline segments located on the first sidewall 321 and the second sidewall 322 to form a circulation pipeline. The first pipeline segments 36 located on the corresponding sidewalls are respectively provided with slots 311.

[0050] Optionally, the circulation pipeline also includes a third pipeline section 39, which is parallel to the height direction H and corresponds to the left plate 15 or right plate 16 of the housing 1, for connecting the pipeline sections of the first side wall 321 and the second side wall 322. The circulation pipeline also includes an auxiliary pipeline section 38, which is respectively disposed at the edge of the first side wall 321 and the second side wall 322, and is approximately perpendicular to the first pipeline section 36, for connecting the third pipeline section 39 to the first pipeline section 36 of the corresponding first side wall 321 or second side wall 322. The inlet pipe 34 and the outlet pipe 35 extend to the side wall corresponding to the right plate 16 of the housing 1 and protrude from the housing 32, which will not be described in detail here.

[0051] It is understood that the shape and size of each pipe section can be the same or different, and no specific limitation is made here. The shape and size of the set circulation pipes can be adapted according to actual needs. Furthermore, the density of the pipes arranged on the first sidewall 321 and the second sidewall 322 is adjustable to adjust the effective heat dissipation area, but the specific density and how to adjust it can be limited according to actual needs, and will not be described in detail here.

[0052] In an optional embodiment, the heating element 4 includes a controller. When the controller is disposed in the slot 311, at least the inner sidewall of the first pipe section 36 opposite to the controller is provided with a plurality of spaced protrusions 361.

[0053] Optional, see Figure 8 For the heat-generating component 4, when the heat-generating component 4 is a circuit board such as a controller, in order to avoid damage, the heat dissipation assembly may also include a cooling conductor 5. The cooling conductor 5 includes a housing 52. When the circuit board is placed on the housing 52, multiple pressure blocks 54 provided between the edge of the circuit board and the housing 52 are used to press the circuit board firmly onto the housing 52, and the circuit board is then restricted on it by the locking strip 53.

[0054] Optionally, guide rails 51 are provided on opposite sides of the outer casing 52 for connecting with the slot 311. To avoid interference between the guide rails 51 and the edge pressure blocks 54, a groove 55 can be provided on the outer casing 52 corresponding to the guide rails 51. The pressure blocks 54 are configured in a Z-shape to fit into the groove 55, ensuring that part of the pressure blocks 54 is located within the groove 55 and does not protrude from the guide rails 51. This ensures that the fit between the guide rails 51 and the slot 311 does not affect the clamping effect on the circuit board. It is important to emphasize that the cooling component 5, while ensuring the stability of the heating element 4 in the measurement and control equipment, allows for contact and engagement with the housing 32 through the outer casing 52, transferring the heat generated by the heating element 4 to the housing 32. Other feasible fits can be used for the specific structure of the cooling component 5, and no specific limitations are made here.

[0055] It is understandable that the multiple protrusions 361 can be distributed in a diamond pattern on the inner wall of the first pipe section 36 to improve the heat exchange effect. The specific arrangement, density, and shape of the multiple protrusions 361 can be adapted according to the requirements and are not specifically limited here.

[0056] Optionally, when the heat-generating component 4 is another electronic component with high heat dissipation requirements, a protrusion 361 can also be provided for the first conduit section 36 corresponding to the electronic component. No specific limitation is made here.

[0057] The circulation pipeline can be a pipeline directly arranged on the outer surface of the first side wall 321 and the second side wall 322, or it can be a structure inside the first side wall 321 and the second side wall 322. No specific limitation is made here.

[0058] In an optional embodiment, when the circulation pipe is located inside the sidewall, the first sidewall 321 and the second sidewall 322 are respectively provided with recesses 332 corresponding to the circulation pipe. The first sidewall 321 is provided with a first cover plate 331, and the second sidewall 322 is provided with a second cover plate 333. The first cover plate 331 and the second cover plate 333 are respectively used to cover the corresponding recesses 332, so that the first sidewall 321 and the first cover plate 331, the second sidewall 322 and the second cover plate 333 together enclose and form a connected flow channel, which serves as the circulation pipe. By using the recesses 332 provided on the sidewall to form a sealed connection with the corresponding cover plates to form a circulation pipe, the cold water in the circulation pipe can directly contact the shell 32 and is closer to the heating element 4, resulting in a better heat exchange effect.

[0059] Understandably, a sealing ring is provided at the position where the edge of the recess 332 mates with the cover plate to form a sealed circulation channel to prevent internal liquid leakage. As for the depth of the recess 332, it can be adjusted adaptively according to the actual situation. The greater the depth of the recess 332, the thinner the side wall thickness between it and the corresponding slot 311, which is more conducive to heat dissipation of the heat-generating component 4. No specific limitation is made here.

[0060] In an optional embodiment, to facilitate the processing of the housing 32 and the circulation pipeline, the housing 32 and the pipes forming the circulation pipeline, such as the recess 332, the inlet pipe 34, and the outlet pipe 35, are manufactured using processes such as wire cutting, CNC machining, and polishing. Furthermore, one or more reinforcing ribs 312 are provided inside the housing 32 to reduce deformation during processing. Optionally, the flow channels corresponding to the inlet pipe 34 and the outlet pipe 35 can also be formed by splicing multiple pipe segments, similar to the flow channels in the sidewall, so that they can be machined onto the housing 32 using CNC machining, reducing processing difficulty.

[0061] In an alternative embodiment, see Figure 4 and Figure 9 In the second heat sink 2, the heat-conducting part 21 is attached to the outer surface of the second side wall 322. The heat-conducting part 21 is a heat sink. The air inlet 121 is located on the bottom plate 12 of the housing 1, and the air outlet 131 is located on the rear plate 13 of the housing 1. Through the heat-conducting part 21, the heat from the heat-generating component 4 to the housing 32 is transferred to the heat-conducting part 21 through contact with the surface of the housing 32. Then, using the sealed space formed by the heat dissipation duct 19, the heat is conducted away from the heat dissipation duct 19 by air cooling, thereby achieving the purpose of air cooling.

[0062] Optionally, the heat-conducting part 21 can also be attached to other side walls of the housing 32, as long as the heat-conducting part 21 can be located in the heat dissipation channel 19 to conduct the heat of the housing 32 to the heat dissipation channel 19. No specific limitation is made here.

[0063] It is understandable that the heat-conducting part 21 may be composed of multiple spaced blades. While the blades are in contact with the surface of the housing 32, the shape formed by the blades facilitates the air entering from the air inlet 121 to carry the heat of the heat-conducting part 21 and discharge it from the air outlet 131. The specific structure of the heat-conducting part 21 is not specifically limited here.

[0064] In an optional embodiment, the second heat sink 2 further includes an air guide plate 22, and the heat dissipation air duct 19 includes an intersecting and connected first air duct 191 and second air duct 192. The first air duct 191 is located in the space formed by the bottom plate 12 and the second side wall 322, and the second air duct 192 is located in the space formed by the air guide plate 22 and the rear plate 13. The air guide plate 22 has an arc-shaped surface 221, which is used to guide the air from the second air duct 192 to the air outlet 131. In this embodiment, the bottom plate 12, rear plate 13, second side wall 322 of the shell 32, and air guide plate 22 of the housing 1 are enclosed by baffles to form a sealed space, thereby forming a heat dissipation duct 19. In this heat dissipation duct 19, since the air inlet 121 is located on the bottom plate 12 and the air outlet 131 is located on the rear plate 13, the heat dissipation duct 19 needs to be composed of a first air duct 191 and a second air duct 192 with an angle. The airflow direction of the first air duct 191 is parallel to the second side wall 322, and the airflow direction of the second air duct 192 is perpendicular to the height direction H of the housing 1. Based on this, the air inlet 121 is positioned opposite the radiator so that the incoming air can flow directly to the radiator. After heat exchange, the carried hot air flows from the first air duct 191 to the second air duct 192 to ensure a better heat exchange effect. As for the air outlet 131, since it is located on the rear plate 13, the axis of the air outlet 131 is perpendicular to the airflow direction of the second air duct 192. In order to increase the rate at which the heat-carrying air flows out of the air outlet 131, the surface of the air guide plate 22 relative to the bottom plate 12 of the housing 1 is set as an arc-shaped surface 221. The edge of the arc-shaped surface 221 connected to the rear plate 13 is close to the air outlet 131 along the height direction H of the housing 1 to increase the airflow speed.

[0065] Based on this, since the air guide plate 22 added to the housing 1 replaces part of the housing 32 to divide the inside of the measurement and control equipment into two separate independent spaces, the side wall of the housing 32 facing the rear plate 13 can be set as an opening 313 so that the accommodating space 31 and part of the accommodating cavity 17 can be connected and combined to form a sealed space. The air guide plate 22 separates the heat dissipation air duct 19 and the sealed space, increasing the space for accommodating the heat-generating component 4 and the accessories connected to the heat-generating component 4, and achieving a reasonable layout.

[0066] Optionally, the side of the housing 32 opposite to the opening 313 is a back plate 323. The back plate 323 is detachably connected to the housing 32 by screws. The back plate 323 is provided with a connection module 323a, which is used to connect with the heating element 4 to achieve communication, power supply and other requirements. Its specific cooperation structure will not be described in detail here.

[0067] In an optional embodiment, for the rear panel 13 of the enclosure 1, in order to form a heat dissipation duct 19 and arrange the fan 23, the rear panel 13 is detachably connected to a connector 132. The connector 132 is connected to the corresponding connector 132 of the heat-generating element 4 in the housing 32 via a cable. When the air guide plate 22 is connected to the rear panel 13, it needs to avoid the connector 132, and a double-peak shielding strip 18 is provided between the two for shielding and sealing.

[0068] Optionally, in the formed heat dissipation duct 19, there can be one or more air outlets 131 corresponding to the opening on the rear panel 13. In this embodiment, two outlets are set as an example. The corresponding air guide plate 22 is a B-type integrated structure design to avoid the connector 132. The fan 23 is set behind the fan panel 231. At the two air outlets 131 respectively connected to the rear panel 13, two sets of fans 23 are formed that communicate with the heat dissipation duct 19. The fans 23 make the air circulating in the heat dissipation duct 19, thereby realizing air cooling.

[0069] Understandably, when assembling the enclosure 1, shell 32, air guide plate 22, etc., to form two independent enclosed spaces, double-peak shielding strips 18 are installed at the surrounding connection points for sealing and shielding. While achieving dual heat dissipation through water cooling and air cooling, two independent spaces are isolated. The internal sealed space houses the heat-generating component 4, which is resistant to salt spray. Furthermore, the independent enclosed space ensures electromagnetic compatibility for the internal heat-generating component 4 during operation, guaranteeing good measurement and control performance. The external sealed space forms a heat dissipation duct 19 for air cooling, enabling operation in salt spray environments and ensuring good heat dissipation performance of the measurement and control equipment.

[0070] This application also provides a measurement and control device, see [link to relevant documentation]. Figure 1 and Figure 2 The enclosure 1 has a receiving cavity 17 and a heat dissipation component as described above, which will not be repeated here.
