Description

Technical Field

[0001] This utility model relates to the field of debugging tooling and instrument technology for radio products, specifically a multi-path controllable power supply. Background Technology

[0002] A multi-channel controllable power supply is a power supply device that can precisely control and adjust the voltage, current and other parameters of multiple output channels through a computer or other control equipment. It has multiple independent output channels and can provide power to multiple different loads at the same time. The output parameters (such as voltage and current) of each channel can be set and controlled independently, which greatly improves the flexibility and efficiency of use.

[0003] In this power supply, during PC testing, it is crucial to power the PC motherboard components with the correct sequence voltage using a multi-channel ATX power supply. In a multi-channel controlled power supply, different components generate varying amounts of heat due to their different working principles and functions. Some components generate a lot of heat, while others generate relatively little. The internal layout also leads to inconsistent arrangement of components with low and high heat generation. During use, the chaotic arrangement of different components causes heat to dissipate, and subsequent repairs become relatively difficult. Based on this, this application provides a multi-channel controlled power supply. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-path controllable power supply, which solves the problem that in existing multi-path controllable power supplies, different components have different working principles and functions, resulting in different heat generation, inconsistent component arrangement, and chaotic combination, leading to heat dissipation and increased difficulty in later maintenance.

[0005] This utility model relates to a multi-path controllable power supply, comprising:

[0006] The power supply body includes two symmetrically arranged support panels and side panels adapted to the support panels. One or more heat dissipation components are installed in the middle of the two side panels for heat dissipation of internal components.

[0007] A frame is provided between the two support panels, and the top and bottom of the frame are respectively snapped with the outer shell;

[0008] The left and right sides of the frame are snapped together with the side panels to form a closed area with the outer shell;

[0009] The inner side of the frame is provided with a support component, which includes two symmetrically arranged support plates and a spacer plate between the two support plates. The support plates are used for distributed mounting of electronic components.

[0010] The top and bottom of the partition plate maintain a fixed distance from one side of the support plate.

[0011] As a further improvement of this utility model, each of the two support panels has a slot on one side that is close to each other. The inner corner of the slot is adapted to the frame, and the inner side of the two slots is engaged with the outer shell at the corner.

[0012] As a further improvement of this utility model, an abutment support component is provided on one side of the frame, and one side of the abutment support component is fixed in contact with one side of the bearing component.

[0014] As a further improvement of this utility model, the partition plate includes a plate body, the middle of which is hollow and has a heat dissipation area. One or more protrusions are symmetrically arranged on the inner side of the heat dissipation area to increase the surface area of ​​the heat dissipation area.

[0015] As a further improvement of this utility model, one or more heat dissipation components are provided on one side of the side plate, and the heat dissipation components are located in the middle of the heat dissipation area of ​​the partition plate.

[0016] As a further improvement of this utility model, the two support panels are respectively provided with a back heat dissipation hole and a front heat dissipation hole to assist the power supply body in heat dissipation.

[0017] As a further improvement of this utility model, one of the support panels is provided with a power plug and a switch on both sides of the front heat dissipation hole, which are used to control the opening and closing of the power supply body.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This utility model solves the problem of inconsistent internal component arrangement and chaotic combination by setting a support component on the inner side of the frame. The two symmetrical support plates of the support component are used for distributed installation of electronic components, which enables different electronic components to be reasonably distributed according to heat generation, working characteristics, etc., which facilitates subsequent maintenance and management.

[0020] The slot of the support panel is engaged with the frame and the outer shell. The abutting support component on one side of the frame uses elastic elements and magnetic plates to abut and fix the load-bearing components, which enhances the stability of the overall power supply structure, effectively resists vibration and external impact, prevents internal components from loosening and shifting, and protects electronic components from damage.

[0021] One or more heat dissipation components are installed in the middle of the side panel. The middle of the partition plate is hollow and has a heat dissipation area.

It can dissipate the heat generated by the electronic components inside the power supply in a timely and effective manner, reduce the internal temperature, and avoid the impact of overheating on the performance and life of the components. The heat dissipation components are located in the middle of the heat dissipation area of ​​the partition plate, which can directly act on the heat concentration area, improve the heat dissipation efficiency, and especially better dissipate heat for electronic components with large heat generation.

[0036] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0037] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0038] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 In multi-process controllable power supplies, different components generate varying amounts of heat due to their different working principles and functions. Some components generate a lot of heat, while others generate relatively little. The internal arrangement of these components leads to inconsistent placement, resulting in a chaotic arrangement during use. This causes heat dissipation and makes subsequent maintenance relatively difficult. Therefore, this application provides a multi-process controllable power supply, comprising:

[0039] The power supply body 1 includes two symmetrically arranged support panels 11 and side plates 19 adapted to the support panels 11. One or more heat dissipation components 110 are installed in the middle of the two side plates 19 for heat dissipation of internal components.

[0040] A frame 16 is provided between the two support panels 11, and the top and bottom of the frame 16 are respectively snapped with the outer shell;

[0041] The left and right sides of the frame 16 are snapped together with the side panels 19 to form a closed area with the outer shell;

[0042] The inner side of the frame 16 is provided with a support component 2, which includes two symmetrically arranged support plates 21, and a spacer plate 22 is provided between the two support plates 21. The support plates 21 are used for distributed mounting of electronic components.

[0043] The top and bottom of the partition plate 22 are respectively kept at a fixed distance from one side of the support plate 21.

[0044] The power supply body 1 includes two symmetrically arranged support panels 11 and side panels 19 that fit with the support panels 11. The symmetrically arranged support panels 11 provide a stable foundation for the entire power supply structure, enabling the power supply to maintain balance and stability during installation and use. The two side panels 19 cooperate with the support panels 11 to jointly construct the external frame 16 of the power supply body 1.

[0045] One or more heat dissipation assemblies 110 are installed in the middle of the two side panels 19. The function of the heat dissipation assembly 110 is to dissipate heat from the internal components of the power supply. During operation of a multi-path controlled power supply, the internal electronic components generate heat. As mentioned in the background art, different electronic components generate varying amounts of heat due to differences in their operating principles and functions, with some components generating significantly more heat. If this heat cannot be dissipated in time, the internal temperature of the power supply will become excessively high, affecting the performance and lifespan of the electronic components, and may even cause malfunctions. Therefore, the installation of the heat dissipation assembly 110 is essential.

[0046] Taking the installation of a single heat dissipation component 110 as an example, the heat dissipation component 110 can be a cooling fan. When the power supply starts working, the cooling fan starts running, using airflow to carry away the heat inside the power supply, thereby reducing the temperature of the internal components. If the power supply generates a large amount of heat, or if higher heat dissipation efficiency is required, multiple heat dissipation components 110 can be installed, and multiple cooling fans can work simultaneously to enhance the heat dissipation effect.

[0047] A frame 16 is provided between the two support panels 11, which serves to connect the two support panels 11 and further support the entire power supply structure. The top and bottom of the frame 16 are respectively snapped with housings, making the installation and removal of the housings convenient. In actual production, workers can quickly snap the housings onto the frame 16 to form the external protective structure of the power supply; and during later maintenance, the housings can be easily removed for inspection and repair of the internal components.

[0048] The left and right sides of the frame 16 are snapped into the side plates 19. Through this snap-fit, the frame 16, the side plates 19, and the outer casing together form a closed area. This closed area can effectively protect the electronic components inside the power supply, preventing damage to the components from external factors such as dust and moisture. It also helps to maintain stable temperature and humidity inside the power supply.

[0049] A support assembly 2 is provided on the inner side of the frame 16. The support assembly 2 includes two symmetrically arranged support plates 21, with a spacer 22 between the two support plates 21. The main function of the support plates 21 is to distribute electronic components. As mentioned in the background art, existing multi-path controllable power supplies suffer from inconsistent internal component arrangement and chaotic combination, leading to heat dissipation and maintenance difficulties. However, the support plate 21 of this multi-path controllable power supply adopts a distributed installation method for electronic components, which allows different electronic components to be rationally distributed and installed on the support plate 21 according to factors such as the heat generation and operating characteristics of the electronic components.

[0050] For example, electronic components that generate a lot of heat can be installed at the edge of the support plate 21, which is more conducive to the heat dissipation component 110 dissipating heat from them; interconnected electronic components that need to work together can be installed in adjacent positions to facilitate the wiring connection and signal transmission between them.

[0051] The top and bottom of the spacer 22 maintain a fixed distance from one side of the support plate 21. This fixed distance serves several purposes. Firstly, it provides space for the installation of electronic components, preventing them from crowding each other and ensuring proper installation and operation. Secondly, the channel formed by the fixed distance facilitates airflow, further promoting heat dissipation and improving heat dissipation efficiency.

[0052] In summary, the above structural design effectively solves the problems mentioned in the background technology, such as chaotic internal component arrangement, heat dissipation, and difficulty in later maintenance, thereby improving the performance and reliability of the power supply.

[0053] Please see Figure 2 , Figure 3 , Figure 4 as well as Figure 5 Each of the two support panels 11 has a slot 15 on one side that is close to each other. The inner corner of the slot 15 is adapted to the frame 16, and the inner side of the two slots 15 is located at the corner and is engaged with the outer shell.

[0054] A contact support component 18 is provided on one side of the frame 16, and one side of the contact support component 18 is fixed in contact with one side of the load-bearing component 2.

[0055] In the multi-path controlled power supply, slots 15 are provided on the sides of the two support panels 11 that are close to each other. The opening of these slots 15 is deliberate, and the size and shape of their inner corners are adapted to the frame 16. When assembling the power supply, the frame 16 can be accurately inserted into the corners of the inner walls of the slots 15. Like two fitting parts, the frame 16 can be firmly installed between the support panels 11, providing a supporting foundation for the entire power supply structure.

[0056] Meanwhile, the inner sides of the two slots 15, located at the corners, also engage with the outer casing. Through this engagement with the inner corners of the slots 15, the outer casing is tightly integrated with the support panel 11 and the frame 16. This engagement method not only ensures the stability of the casing installation but also makes the overall structure of the power supply more compact. In practical applications, when the power supply is subjected to vibration or external impact, the fit and engagement between the slots 15, the frame 16, and the outer casing effectively prevents loosening or displacement, thereby protecting the internal electronic components of the power supply from damage.

[0057] For example, when installing the frame 16 into the slot 15 of the support panel 11, the worker only needs to slowly push the frame 16 along the inner wall of the slot 15 until the frame 16 is completely fitted with the corner of the inner wall of the slot 15. Then, align the outer shell with the snap-fit ​​position located at the corner on the inner side of the slot 15 and press it down slightly to achieve a secure installation of the outer shell.

[0058] A contact support assembly 18 is provided on one side of the frame 16. The contact support assembly 18 serves to hold the carrier assembly 2 in place. The carrier assembly 2 includes two symmetrically arranged carrier plates 21 and a spacer 22 between them, for distributed mounting of electronic components. However, simply installing the frame 16 and the carrier assembly 2 may not guarantee the stability of the carrier assembly 2 inside the power supply. Especially during power supply operation, some vibration may occur, which can easily cause the carrier assembly 2 to shake, thereby affecting the normal operation of the electronic components.

[0059] One side of the abutting support component 18 is fixed against one side of the carrier component 2, which is equivalent to adding an extra support point to the carrier component 2. It can effectively restrict the movement of the carrier component 2 and keep it in a stable position inside the power supply. When the power supply is subjected to external vibration or impact, the abutting support component 18 can disperse these external forces and reduce the impact on the carrier component 2 and electronic components.

[0060] For example, the abutment support component 18 can be a flexible support structure. During installation, the abutment support component 18 is installed on one side of the frame 16, and then its position is adjusted so that it is in close contact with one side of the load-bearing component 2. When the load-bearing component 2 is subjected to vibration and tends to move, the abutment support component 18 will undergo elastic deformation, using elastic force to counteract the impact of vibration, thereby ensuring the stability of the load-bearing component 2.

[0061] In summary, the design of the slot 15 in the support panel 11 and the setting of the abutment support component 18 further enhance the structural stability of the multi-path controllable power supply, solve the problem of abnormal operation of electronic components that may be caused by internal structural instability, and improve the reliability and service life of the power supply.

[0062] Please see Figure 5 , Figure 6 Figure 7 The abutment support component 18 includes a mounting frame 181, an elastic element 183 is provided on the inner side of the mounting frame 181, and a magnetic suction plate 182 is installed on one side of the elastic element 183. The magnetic suction plate 182 magnetically abuts against the two support plates 21 and the spacer plate 22 that make up the support component 2.

[0063] The partition plate 22 includes a plate body 223, which is hollow in the middle and has a heat dissipation area 221. One or more protrusions 222 are symmetrically arranged on the inner side of the heat dissipation area 221 to increase the surface area of ​​the heat dissipation area 221.

[0064] The anti-collision support assembly 18 serves to secure the load-bearing assembly 2 by resisting its movement. The anti-collision support assembly 18 includes a mounting frame 181, which provides basic mounting and support. It is positioned on one side of the frame 16, providing space and a fixed location for the elastic element 183 and the magnetic plate 182.

[0065] An elastic element 183 is provided on the inner side of the mounting frame 181. The elastic element 183 has the characteristic of elastic deformation, such as a spring, or is composed of two magnets with the same magnetic poles. It can deform and compress when subjected to external force, and return to its original shape after the force is removed. This elastic characteristic allows the elastic element 183 to adaptively adjust according to the position and state of the supporting component 2. For example, when the supporting component 2 undergoes a small displacement due to vibration or other reasons during power supply operation, the elastic element 183 can absorb and buffer this displacement through its own elastic deformation, preventing the supporting component 2 from affecting the normal operation of electronic components due to excessive displacement.

[0066] A magnetic suction plate 182 is installed on one side of the elastic element 183. The magnetic suction plate 182 is magnetic and magnetically abuts against the two support plates 21 and the spacer plate 22 that make up the support assembly 2. This magnetic abutment not only provides a certain fixing force to stably fix the support assembly 2 in a suitable position, but also has a certain degree of flexibility. When it is necessary to disassemble, repair or adjust the support assembly 2, it is only necessary to overcome the magnetic force between the magnetic suction plate 182 and the support plates 21 and the spacer plate 22 to easily separate them. Moreover, the magnetic abutment can also reduce the wear and damage that may be caused by rigid contact to a certain extent, and extend the service life of the support assembly 2 and the abutment support assembly 18.

[0067] For example, during power supply assembly, the mounting frame 181 is first fixed to one side of the frame 16, then the elastic element 183 is installed inside the mounting frame 181, and then the magnetic plate 182 is installed on one side of the elastic element 183. Finally, the bearing assembly 2 is placed in a suitable position, and the magnetic plate 182 will automatically adhere to the bearing plate 21 and the spacer 22, completing the fixation of the bearing assembly 2 by the contact support assembly 18.

[0068] The partition plate 22 also has a unique design and function in the supporting assembly 2. The partition plate 22 includes a plate body 223, which is hollow in the middle and has a heat dissipation area 221. This hollow design and the opening of the heat dissipation area 221 provide a channel for air circulation. When the power supply is working, the internal electronic components generate heat, and air can flow through the heat dissipation area 221 inside the supporting assembly 2 to carry away the heat, thereby achieving the purpose of heat dissipation.

[0069] One or more raised strips 222 are symmetrically arranged on the inner side of the heat dissipation area 221. The raised strips 222 are designed to increase the surface area of ​​the heat dissipation area 221. According to the principle of heat transfer, the larger the heat dissipation area of ​​an object, the higher the heat dissipation efficiency. The presence of the raised strips 222 significantly increases the surface area of ​​the heat dissipation area 221, enabling more effective heat exchange with the air and improving the heat dissipation effect.

[0070] For example, when heat inside the power supply is transferred to the heat dissipation area 221 of the partition plate 22 through the air, the protrusions 222 can increase the contact area between the air and the heat dissipation area 221, allowing more heat to be quickly dissipated into the air. If the heat dissipation requirement is large, multiple protrusions 222 can be set in the heat dissipation area 221 to further improve the heat dissipation efficiency. Moreover, the symmetrical arrangement of the protrusions 222 helps to ensure uniform airflow within the heat dissipation area 221 and avoids uneven local heat dissipation.

[0071] In summary, the design of the anti-support component 18 and the spacer plate 22 further optimizes the structure and heat dissipation performance of the multi-path controllable power supply, solves the problems related to internal component arrangement and heat dissipation mentioned in the background art, and improves the stability and reliability of the power supply.

[0072] Please see Figure 5 , Figure 6 , Figure 7 as well as Figure 8 One or more heat dissipation components 110 are provided on one side of the side plate 19, and the heat dissipation components 110 are located in the middle of the heat dissipation area 221 of the partition plate 22.

[0073] The two support panels 11 are respectively provided with a rear heat dissipation hole 17 and a front heat dissipation hole 13 in the middle part, which are used to assist the power supply body 1 in heat dissipation.

[0074] One of the support panels 11 is located on both sides of the front heat dissipation hole 13, and a power plug 12 and a switch 14 are respectively provided to control the opening and closing of the power supply body 1.

[0075] One or more heat dissipation components 110 are provided on one side of the side plate 19, and these heat dissipation components 110 are located in the middle of the heat dissipation area 221 of the partition plate 22. This design is for more efficient heat dissipation of the power supply's internal components. Since the internal electronic components generate heat when the power supply is operating, the heat dissipation area 221 in the middle of the partition plate 22 is a key location for airflow and heat concentration. Placing the heat dissipation components 110 here allows them to directly act on the area where heat is concentrated, accelerating airflow and more effectively removing heat.

[0076] When the power supply starts working, the internal electronic components generate heat, and the hot air naturally rises and accumulates in the heat dissipation area 221 of the partition plate 22. At this time, the heat dissipation components 110 start operating, such as the cooling fan, accelerating the airflow. Air is drawn out from the heat dissipation area 221, while cool air from the outside enters the power supply from other gaps or ventilation holes, forming a good air circulation, thereby reducing the internal temperature of the power supply. If the power supply has a large power and generates a lot of heat, multiple heat dissipation components 110 can be installed on the side plate 19, and multiple heat dissipation components 110 can work simultaneously to enhance the heat dissipation effect.

[0077] The two support panels 11 are respectively provided with a rear heat dissipation hole 17 and a front heat dissipation hole 13 in the middle part, which are used to assist in the heat dissipation of the power supply body 1. The rear heat dissipation hole 17 and the front heat dissipation hole 13 work together to further improve the air circulation system inside the power supply.

[0078] When the heat dissipation assembly 110 is operating, air enters the power supply through the front heat dissipation vent 13, absorbs heat as it passes over the internal electronic components, and then the hot air is exhausted through the rear heat dissipation vent 17. This airflow process continuously removes heat from the power supply, maintaining a stable internal temperature. Furthermore, the placement of the heat dissipation vents in the center of the support panel 11 facilitates even airflow within the power supply, preventing localized overheating. For example, during prolonged high-load operation, the rear heat dissipation vent 17 and the front heat dissipation vent 13 ensure sufficient airflow, preventing heat accumulation from affecting the performance and lifespan of the electronic components.

[0079] One of the support panels 11 has a power plug 12 and a switch 14 respectively located on both sides of the front heat dissipation hole 13. The function of the power plug 12 is to provide power input to the power supply body 1. When the power plug 12 is plugged into a suitable power socket, the power supply body 1 can obtain the required power and start working.

[0080] Example 2, as Figure 7 As shown, in this embodiment, the spacer 22 can be a flat plate structure made of semiconductor material. The outlet section that runs through the middle is the heat generation area. Together with the heat dissipation assembly 110 of the side plate 19, it can dissipate heat in time. At the same time, the end near the two support plates 21 is the cooling area. By controlling the appropriate temperature, the air drawn by the heat dissipation assembly 110 is allowed to pass through the cooling area during the cooling process, thereby reducing its temperature. At this time, the temperature of electronic components in the area of ​​the support plate 21 can be reduced, thereby improving the service life of the power supply.

[0081] Furthermore, during use, the spacer 22 can be attached to the two support plates 21. At this time, the cooling areas on both sides are in direct contact with the support plates 21, which can better improve the heat dissipation capacity. In order to further improve the heat conduction capacity, a heat-conducting medium, such as phase change silicone grease, can be added to the attached area to transfer heat as quickly as possible.

[0082] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
