[0019] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0020] Figure 1 A diagonal front view of a case of a nuclear magnetic resonance functional component is provided for the embodiments of the present application.

[0021] Figure 2 A diagonal front view of a case shell without installed modules is provided for the embodiments of the present application.

[0022] As shown in Figure 1 , Figure 2 , the present application provides a case 100 of a nuclear magnetic resonance functional component, the functional component can be a radio frequency amplifier or a gradient amplifier. The case 100 comprises: a shell 110, forming a containing space 111 with an open end 112; a separation component 120, arranged on the shell 110, dividing the containing space 111 into a plurality of sub-spaces 1111 in communication with the open end 112; and a plurality of functional modules 130, penetrating the open end 112 and corresponding to be plugged into the plurality of sub-spaces 1111.

[0023] In the embodiments provided by the present application, the functional modules penetrate the open end and correspond to be plugged into the plurality of sub-spaces, this plugging mode can realize quick replacement of each functional module at the maintenance site, solving the problem of the maintenance cycle of the client device. The separation component of the case divides the containing space into a plurality of sub-spaces, ensuring that each functional module can reduce the interference of other modules after being plugged in and running. This design makes each module can work independently, reducing the mutual influence.

[0024] As shown in Figure 1 , in an example, the plurality of sub-spaces 1111 comprises a first space 11111 and a second space 11112 stacked from bottom to top, and the plurality of functional modules 130 comprises a power module 131, a heat dissipation module 132 and a power module 133, the power module 131 and the heat dissipation module 132 are arranged in the first space 11111, and the power module 133 is arranged in the second space 11112.

[0025] Exemplarily, the power module 131 and the heat dissipation module 132 are plugged and arranged in the first space 11111, and the first space 11111 can belong to the containing space 111 close to the bottom of the case 100. The shell 110 and the separation component 120 not only provide physical protection, but also isolate each module, preventing electromagnetic interference and other potential interference factors from affecting the normal work of the functional module 130. The power module 131 and the heat dissipation module 132 can be integrated together.

[0026] By setting the power module 131 and the heat dissipation module 132 in the first space 11111, and the power module 133 in the second space 11112, the space utilization is optimized, making the internal layout of the device more reasonable, which helps heat dissipation and the overall performance of the device. By plugging multiple functional modules 130 in multiple sub-spaces 1111, modular design is achieved. Each module can be independently installed and removed, facilitating maintenance and replacement. In addition, modular design allows users to add or remove individual functional modules 130 as needed, providing great flexibility and scalability.

[0027] As shown in Figure 1 , Figure 2 In another embodiment, the partition component 120 includes a guide rail structure 121 arranged on the inner wall of the housing 110 and extending along the plugging direction of the functional module 130, and a support structure 122 mounted on the inner wall of the guide rail structure 121 and / or the housing 110.

[0028] Illustratively, the guide rail structure 121 provides accurate guidance and positioning functions for the modules, making the installation and replacement of the functional module 130 more convenient and fast, reducing the operation difficulty and time cost. In addition, the standardized guide rail design improves the compatibility between different functional modules 130, reduces the design difficulty of the internal structure of the case 100, makes the structure compact, and facilitates subsequent upgrading and maintenance. The support structure 122 is mainly used to fix and support the functional modules 130 in the case 100, especially to bear the functional modules 130 with large weight, such as the power module 133. The power module 133 is installed in the second space 11112 of the housing 110 through the support structure 122. The support structure 122 is mounted on the inner wall of the guide rail structure 121, and can also be mounted on the inner wall of the housing 110 and above the guide rail structure 121. The guide rail structure 121 and the support structure 122 cooperate with each other to enable the module to move smoothly along the predetermined path when being loaded or unloaded, reduce friction and damage during installation and removal, and improve the safety of the case. The support structure 122 can be generally in the shape of an I-beam and a U-beam, which is conducive to increasing the stability of connection with the guide rail structure 121.

[0029] In another example, the partition component 120 includes a first partition component 123 and a second partition component 124; the first partition component 123 is located between the first space 11111 and the second space 11112 (for separating the first space 11111 and the second space 11112), and the second partition component 124 is located in the second space 11112 (for further separating the second space 11112 into two sub-spaces); the power module 133 can also include a first power module and a second power module, and the first power module and the second power module are respectively plugged into the two sub-spaces of the second space 11112.

[0030] For example, the first power module and the second power module can be stacked in the second direction Y. The stacked power modules can improve the power output to meet the high power requirements of the nuclear magnetic resonance functional components. The stacked design can also save space and improve heat dissipation efficiency. The control module 134 is responsible for the coordination and control of the overall system. The control module 134 can be set in the second space 11112 near the top of the chassis 100 for easy maintenance and upgrades.

[0031] In this embodiment of the invention, the chassis adopts a front-mounted modular stacking installation method, which ensures that each functional module does not affect or interfere with each other. This front-mounted modular stacking installation method enables rapid on-site replacement of functional modules. It effectively solves the equipment maintenance cycle problem for clients, greatly reduces equipment downtime, and improves equipment availability. Simultaneously, through the aforementioned overall modular design, including the rational layout of functional modules, it achieves both product performance stability, ensuring that the MRI functional components accurately output the required radio frequency power and maintain stable radio frequency signals under various complex operating conditions; and operational reliability, reducing equipment failures caused by factors such as water leakage, poor heat dissipation, or electromagnetic interference, thereby extending the equipment's service life.

[0032] Figure 3 This is a rear view of the chassis of a nuclear magnetic resonance functional component provided for an embodiment of the present invention.

[0033] Figure 4 A rearward view of the power module provided in an embodiment of this utility model.

[0034] like Figure 1 , Figure 3 As shown, in another example, the multiple functional modules 130 also include a control module 134. The control module 134 is disposed in the second space 11112 and located on the side of the power module 133 away from the power supply module 131. The inner wall of the housing 110 corresponding to the second space 11112 of the housing 110 includes a mounting hole 114. The control module includes a mounting post 1341, and the control module 134 is snapped into the mounting hole 114 through the mounting post 1341.

[0035] Exemplarily, the power module 131, the heat dissipation module 132, the power module 133 and the control module 134 can be plugged along the first direction X, and the power module 131, the heat dissipation module 132, the power module 133 and the control module 134 can be stacked in the plurality of accommodating spaces 111 along the second direction Y, and the second direction Y can be perpendicular or close to perpendicular to the first direction X. Moreover, the control module 134 is generally light in weight, and can be mounted on the power module 133 through the mounting column 1341 and the mounting hole 114, without being borne by the partition component 120, so that the structure of the case 100 is simplified and the overall weight is reduced.

[0036] In another example, the distance between the control module 134 and the power module 133 is greater than a distance threshold. For example, the power module 133 includes a first power module and a second power module, and the distance between the control module 134 and the power module 133 being greater than the distance threshold includes that the distance between the second power module and the first power module is less than the distance between the control module 134 and the first power module, in other words, the second power module is above the first power module, the control module 134 is above the second power module, and the second power module is closer to the control module 134. The distance threshold is set to prevent the power module 133 from interfering with the control module 134.

[0037] As shown in Figure 4 There is a shielding shell 153 outside the power module 133, which can protect the power module 133 and shield the signals generated by the power module 133.

[0038] The embodiment of the utility model adopts the above design, so that the space utilization in the case is more compact and efficient. Moreover, the power module will generate strong electromagnetic radiation when working, and the distance between the control module and the power module is greater than the distance threshold, which helps to reduce the electromagnetic interference of the control module by the power module and ensure the stability of the signal processing and control function of the control module.

[0039] As shown in Figure 1 In another embodiment of the utility model, the shell 110 further includes a window 113 communicating with the accommodating space 111, the window 113 is opposite to the opening 112, and the case 100 further includes a limiting structure 150 arranged on the shell 110 and located at the position of the window 113, for limiting the plurality of functional modules 130.

[0040] Exemplarily, the functional module 130 can be correspondingly plugged into the plurality of subspaces 1111 along the opening 112 in the direction of the window 113. Taking the plugging process of the power module 133 as an example, the power module 133 can be plugged along the opening 112 in the direction of the window 113 under the guidance and support provided by the guide rail structure 121 and the support structure 122. During the plugging process of the power module 133, the limiting structure 150 arranged at the position of the window 113 can limit the power module 133. When the power module 133 is inserted into the predetermined position, the limiting structure 150 can prevent the power module 133 from continuing to move backward, so as to accurately determine the final installation position of the power module 133 in the cabinet 100 and realize the self-locking function, thereby improving the efficiency of module installation, disassembly and maintenance. In addition, during the plugging process of the functional module 130, the spring of the screw component can be used to realize the functions of adjusting the module position and self-locking.

[0041] As shown in Figure 1 , in another embodiment, the cabinet 100 further comprises a panel structure 140 arranged at the position of the opening 112 of the shell 110 and used for fixing the plurality of functional modules 130.

[0042] Exemplarily, the panel structure 140 is arranged at the position of the opening 112 and is used for tightly fixing the functional module 130 from the opening 112, so as to effectively ensure the installation position and fixing strength between the modules.

[0043] As shown in Figure 1 , Figure 3 , and Figure 4 , the heat dissipation module 132 comprises a water cooling system 1321 arranged at the side of the power module 133 away from the power module 133. The water cooling system 1321 comprises a water distributor 13211 and a pipeline 13212 in communication with the water distributor 13211. The pipeline 13212 is arranged on the side of the shell 110 opposite to the opening 112 and is in communication with the water inlet pipe and the water outlet pipe of the power module 133.

[0044] Exemplarily, in order to effectively avoid the influence on the functional module 130 when the water cooling system 1321 leaks, the water cooling system 1321 can be inserted and arranged in the first space 11111, and the water distributor 13211 can be inserted and arranged in the first space 1111 at a position close to the bottom surface of the cabinet in the second direction Y. The water distributor 13211 can include a total water inlet and a total water outlet, a plurality of water outlet branch openings in communication with the total water inlet, and a plurality of water return branch openings in communication with the total water outlet. The pipeline 13212 can include a plurality of water inlet branch pipes and a plurality of water return branch pipes, the plurality of water inlet branch pipes are in communication with the plurality of water outlet branch openings in correspondence, and the plurality of water return branch pipes are in communication with the plurality of water return branch openings in correspondence.

Of course, the plurality of water inlet branch pipes and the plurality of water return branch pipes can also be in communication with other functional modules requiring cooling. The water cooling plate 220 can be arranged in the power module, and the power components of the power module can be arranged on the water cooling plate 220. The water inlet pipe and the water outlet pipe are in communication with the water cooling plate 220. The water distributor can be a plate, for example, obtained by processing a metal plate.

[0045] In the embodiment of the utility model, by integrating the water distributor of the water cooling system and the power module in the first space of the cabinet, not only can the power module and the power module be effectively cooled, so that the temperature of the power module and the power module is relatively stable, and the service life and use performance thereof are improved. Moreover, the utilization efficiency of the accommodation space of the cabinet can be improved. The above-mentioned integrated design makes the water cooling system and other functional modules form an organic whole, so that the running state of the water cooling system and the temperature of the functional module can be centrally monitored and controlled through unified management, and the efficiency of maintenance and management is improved.

[0046] As shown in Figure 1 , Figure 3 indicated, in another example, the panel structure 140 is provided with an air inlet a in communication with the accommodation space 111, and the shell 110 is provided with an air outlet b opposite the opening 112.

By arranging the air inlet a and the air outlet b of the air cooling system opposite the power module 131, the heat dissipation efficiency of the air cooling system on the power module 131 can be improved, and the utilization rate of the space can be optimized.

[0048] Exemplarily, asFigure 3 、 Figure 4 As shown in FIGS. 12 and 13, for other functional modules 130 that need to dissipate heat and are not connected with the pipeline 13212, the utility model also adopts an embedded water-cooled plate design scheme, for example, the water-cooled plate 220 can be arranged at the window 113 of the case 100 and is arranged to be closely attached to the power module 133, and other components of the power module 133 can be arranged on the water-cooled plate 220 to dissipate heat from the other components by heat conduction.

[0049] Therefore, in the embodiments of the utility model, while following the modularization, convenient maintenance, high performance and multi-levelization of the case design structure, the water cooling system can be designed and integrated in the single module.
