Description

Technical Field

[0001] The invention belongs to the technical field of module power supplies, in particular to an industrial module power supply with a wide voltage output. Background Art

[0002] Modular power refers to a power supply directly mounted on a printed circuit board. It plays a wide range of roles in circuits. It can provide power for digital or analog loads such as DSP, FPGA, and microprocessors, and save space on the circuit board to a large extent. With the rapid development of data services and the continuous promotion of distributed power supply systems in recent years, the growth rate of modular power has exceeded that of primary power. In addition, modular power has the advantages of isolation, strong anti-interference ability, self-protection function, and easy integration, and is widely used in most industries.

[0003] The operating temperature of the internal components of the wide voltage output industrial power module will directly affect the life of the power module. The lower the temperature of the components, the longer the service life of the power module. It is inevitable that there will be some loss during use. The heat dissipation conditions of the power module can be improved to reduce its temperature rise, thereby extending its service life. However, with the development of technology, the size of the power module is getting smaller and smaller, the power density is getting larger and larger, and the conversion efficiency is getting higher and higher, so the heat generated will also increase. Due to the reduction in size, the heat dissipation area of ​​the power module becomes more limited, resulting in a decrease in the heat dissipation effect. The increase in operating temperature will increase the power consumption of the power module, resulting in a significant reduction in service life. Moreover, the shell of the existing power module is relatively simple.

[0004] In view of this, in order to overcome the above technical problems, the present invention designs and develops a wide voltage output industrial module power supply to solve the above technical problems. Summary of the invention

[0005] The technical problem to be solved by the present invention is: the wide voltage output industrial module power supply provided by the present invention solves the problem that the operating temperature of the internal components of the wide voltage output industrial module power supply will directly affect the life of the module power supply. The lower the temperature of the components, the longer the service life of the module power supply. It is inevitable that there will be a certain loss during use. The heat dissipation conditions of the module power supply can be improved to reduce its temperature rise, thereby extending its service life. However, with the development of science and technology, the size of the module power supply is getting smaller and smaller, the power density is getting larger and larger, and the conversion efficiency is getting higher and higher, so the heat generated will also increase accordingly. Due to the reduction in size, the heat dissipation area of ​​the module power supply becomes more limited, resulting in a reduction in the heat dissipation effect. In turn, the increase in the operating temperature will aggravate the power consumption of the module power supply, resulting in a significant reduction in the service life.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] The embodiment of the present invention provides a wide voltage output industrial module power supply, which solves the problem that the operating temperature of the internal components of the wide voltage output industrial module power supply will directly affect the life of the module power supply. The lower the temperature of the components, the longer the service life of the module power supply. It is inevitable that there will be a certain loss during use. The heat dissipation conditions of the module power supply can be improved to reduce its temperature rise, thereby extending its service life. However, with the development of science and technology, the size of the module power supply is getting smaller and smaller, the power density is getting larger and larger, and the conversion efficiency is getting higher and higher, so the heat generated will also increase. Due to the reduction in size, the heat dissipation area of ​​the module power supply becomes more limited, resulting in a reduction in the heat dissipation effect. In turn, the increase in operating temperature will increase the power consumption of the module power supply, resulting in a significant reduction in the service life. In addition, the shell of the existing module power supply is relatively single. Technical problems.

[0043] The technical solution in the embodiment of the present invention is to solve the above-mentioned technical problems, and the overall idea is as follows: the existing power module 1 is installed in the shell assembly, and the shell assembly plays a role of stable support for the power module 1. The shell assembly is connected to a heat dissipation assembly, and the heat dissipation assembly can dissipate heat and cool the working power module 1 to avoid temperature rise and increase the power consumption of the power module 1, thereby greatly extending the service life of the module power supply.

[0044] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0045] The present invention provides an industrial module power supply with a wide voltage output, comprising a power module 1 and a mounting base 2, and further comprising:

[0046] A housing assembly, which is used to fix and install the power module 1 and plays a role of stable support. The housing assembly is respectively connected to the power module 1 and the mounting seat 2;

[0047] A heat dissipation component, which is used to dissipate heat and cool the power module 1 in the housing component;

[0048] The heat dissipation component is connected to the housing component.

[0049] The wide voltage output industrial module power supply of the present invention comprises an existing power module 1 and a mounting seat 2, wherein the mounting seat 2 is two mounting columns distributed front and back, and further comprises a housing component connected to both the power module 1 and the mounting seat 2, and the housing component is connected to a heat dissipation component;

[0050] Compared with the existing wide voltage output industrial module power supply, a fan is installed on the outside of the power module 1 to blow air to the power module 1 through forced air cooling. Although this can achieve heat dissipation and cooling of the working power module 1, the form of fan cooling is relatively simple, which is simply to blow air to the power module 1 through the fan, so the heat dissipation and cooling effect that can be achieved is not good;

[0051] First, the shell assembly of the present invention can provide a stable support for the power module 1, firmly install the power module 1 in the shell assembly, and enrich the packaging shell of the existing module power supply, so that the shell is no longer so simple. Then, the power module 1 is cooled and dissipated by the heat dissipation assembly connected to the shell assembly, so as to avoid the continuous heating of the power module 1 during operation, increase the power consumption of the internal components, and thus seriously shorten the service life of the module power supply. Therefore, the service life of the module power supply can be greatly extended by the heat dissipation assembly.

[0052] As a specific embodiment of the present invention, the housing assembly includes:

[0053] A bottom plate 3, which is circular and connected to the mounting seat 2;

[0054] A top plate 4, which is circular and located at the upper end of the bottom plate 3;

[0055] Support columns 5, the support columns 5 connecting the bottom plate 3 and the top plate 4;

[0056] The power module 1 is installed on the upper surface of the base plate 3 .

[0057] The shell assembly of the present invention includes a circular bottom plate 3 connected to a mounting seat 2, a support column 5 is fixedly connected to the upper surface of the bottom plate 3, a circular top plate 4 is fixedly connected to the upper end surface of the support column 5, and the top plate 4 corresponds to the position of the bottom plate 3, the support column 5 connects the top plate 4 and the bottom plate 3, and a space for installing the power module 1 is reserved on the upper surface of the bottom plate 3, so that the power module 1 can be installed on the bottom plate 3, which plays a role of stable support, and the gap formed in the middle of the top plate 4 and the bottom plate 3 arranged up and down provides sufficient heat dissipation space for the working power module 1, although the volume is reduced, the remaining heat dissipation area is sufficient, the side wall is all gaps except for the support column 5 which plays a supporting role, and there will be no problem of reduction of heat dissipation area due to volume reduction, ensuring that the power module 1 can contact the air, has the effect of natural cooling of the air, and plays the effect of preliminary cooling and heat dissipation of the power module 1, and at the same time, when the shell material remains unchanged, the volume of the cylindrical cavity is larger than that of the cubic cavity.

[0058] As a specific embodiment of the present invention, the heat dissipation component includes:

[0059] A heat dissipation motor 6, wherein the heat dissipation motor 6 is fixedly connected to the upper surface of the top plate 4;

[0060] The heat sink 7 is a circular wall 72 with a cross fan 71 fixedly connected in the middle, located between the top plate 4 and the bottom plate 3, and fixedly connected to the output shaft of the heat dissipation motor 6;

[0061] The annular wall 72 of the heat dissipation plate 7 has an extending wall 721 extending downward;

[0062] Heat dissipation holes 73, the heat dissipation holes 73 are evenly opened on the surface of the extension wall 721;

[0063] Heat dissipation openings 31, which are respectively provided on the surfaces of the bottom plate 3 and the top plate 4;

[0064] The heat dissipation plate 7 can rotate relative to the top plate 4 and the bottom plate 3;

[0065] The cross sector 71 is fixedly connected to the annular wall 72 .

[0066] The heat dissipation assembly of the present invention includes a heat dissipation motor 6 fixedly connected to the upper surface of the top plate 4, and a heat dissipation plate 7 fixedly connected to the output shaft of the heat dissipation motor 6 is installed between the top plate 4 and the bottom plate 3. When the heat dissipation motor 6 works, the output shaft drives the heat dissipation plate 7 to rotate between the top plate 4 and the bottom plate 3. The heat dissipation plate 7 is formed by a cross fan blade 71 and a circular wall 72 fixedly connected, and an extension wall 721 of the circular wall 72 extends downward to the surface of the bottom plate 3, and the extension wall 721 can slide in the slide groove on the surface of the bottom plate 3. A heat dissipation hole 73 is opened on the extension wall 721 of the heat dissipation plate 7, and a plurality of heat dissipation ports 31 are opened on the surfaces of the bottom plate 3 and the top plate 4 and penetrate the surface. In this way, when the power source heat dissipation motor 6 is working, the output shaft rotates to drive the heat dissipation plate 7 to rotate between the top plate 4 and the bottom plate 3, and the cross fan blade 71 of the heat dissipation plate 7 rotates through the heat dissipation port 31 of the top plate 4 to dissipate the outside Air at normal temperature is sucked in and blown toward the power module 1 installed on the upper surface of the base plate 3 to cool it down, and then discharged through the heat dissipation port 31 of the base plate 3. Due to the rotation of the cross fan blades 71 together with the annular wall 72, air can enter from the side of the wide voltage output industrial module power supply, thereby achieving a cooling effect and accelerating the air flow rate inside the shell assembly. Part of the air enters the heat sink 7 through the heat dissipation holes 73 opened on the surface of the extended wall 721 of the heat sink 7, so that the annular wall 72 not only plays the role of a part of the shell, but also improves the heat dissipation effect, thereby achieving the cooling of the power module 1 together, avoiding continuous work that causes the temperature of the power module 1 to rise, thereby increasing the power consumption of internal devices, and seriously shortening the service life of the module power supply. The heat dissipation and cooling of the power module 1 by the heat dissipation assembly can greatly extend the service life of the module power supply.

[0067] As a specific implementation of the present invention, the heat dissipation motor 6 is covered with a protective shell 61 , the upper half of the outer surface of the protective shell 61 is provided with threads, and the center of the bottom plate 3 is provided with a threaded hole 32 .

[0068] The heat dissipation motor 6 of the present invention is covered with a protective shell 61 on the outside, and the protective shell 61 can protect the heat dissipation motor 6. The outer surface of the upper half of the protective shell 61 is provided with threads, and a threaded hole 32 is provided at the center of the bottom plate 3. In this way, the number of module power supplies can be adjusted according to the voltage value requirements of the module power supply. It is only necessary to install the threaded hole 32 of the upper module power supply bottom plate 3 on the protective shell 61 of the lower module power supply through a threaded connection. The operation is simple. Because only the upper half of the protective shell 61 has threads on the surface, a part of the heat dissipation space will be left between the bottom plate 3 of the upper module power supply and the top plate 4 of the lower module power supply. When the heat dissipation plate 7 of the heat dissipation assembly of the upper module power supply is working, the air can still be discharged through the heat dissipation port 31 of the bottom plate 3 to ensure the heat dissipation effect of the upper and lower module power supplies. Similarly, the number of module power supplies can be increased or decreased according to needs.

[0069] As a specific implementation of the present invention, the support column 5 is triangular in shape.

[0070] The support columns 5 of the present invention are all in the shape of a triangle. As is known to all, the triangle has the best firmness. As far as a module power supply is concerned, the support column 5 serves to connect and stabilize the top plate 4 and the bottom plate 3. For multiple module power supplies stacked together by threaded connections, the module power supply at the bottom needs to bear all the weight. Therefore, designing the support column 5 of the module power supply to be in a triangular shape is the most stable and can withstand greater pressure, thereby avoiding the problem that the support column 5 cannot hold up due to excessive weight.

[0071] As a specific embodiment of the present invention, the diameter of the heat dissipation hole 73 is small inside and large outside;

[0072] The diameter of the heat dissipation hole 73 of the present invention is small inside and large outside. The diameter of the heat dissipation hole 73 on the outer wall of the extension wall 721 is larger than that of the inner wall. The reduction of the diameter from the outside to the inside can accelerate the air flow rate. In addition to the air flow rate formed by the rotation speed of the heat dissipation plate 7 itself, the diameter design of the heat dissipation hole 73 further accelerates the air flow rate, so that the air intensity entering the shell assembly is greater, the heat dissipation effect on the power module 1 is improved, and the temperature rise of the internal components of the power module 1 is reduced, thereby greatly extending the service life of the module power supply.

[0073] As a specific embodiment of the present invention, the left and right sides of the lower surface of the bottom plate 3 are fixedly connected with hinge seats 33, the hinge seats 33 are rotatably connected with a fixed plate 8, and a limit plate 331 is provided at the upper end of the hinge seat 33.

[0074] The left and right side walls of the lower surface of the bottom plate 3 of the present invention are fixedly connected with an articulated seat 33, a fixed plate 8 is rotatably connected inside the articulated seat 33, and a limiting plate 331 is fixedly connected to the upper end of the articulated seat 33, the module power supply is installed on the mounting seat 2 through the fixing plate 8, which plays a stabilizing role, and the articulated seat 33 can enable the fixing plate 8 to rotate, and the limiting plate 331 is fixed on the upper end of the articulated seat 33, so that the fixing plate 8 can only rotate downward, and the fixing plate 8 is connected to the mounting seat 2 when necessary. If multiple module power supplies need to be superimposed, the fixing plate 8 of the upper module power supply can be rotated downward and retracted to avoid occupying the usable space series and causing unnecessary scratches.

[0075] As a specific implementation of the present invention, the positions of the fixing plate 8 and the hinge seat 33 are slightly higher than the lower surface of the bottom plate 3, and a rubber gasket 9 is fixedly connected to the lower wall of the fixing plate 8.

[0076] The installation position of the fixing plate 8 and the hinge seat 33 of the present invention is slightly higher than the lower surface of the base plate 3. A rubber gasket 9 is fixedly connected to the lower surface of the fixing plate 8. In some special occasions, the intensity of mechanical vibration is relatively large, which causes the module power supply to vibrate. If the fixing plate 8 is used directly for fixing, it is easy to cause the fixing plate 8 to break due to the strong vibration stress, resulting in the failure of the module power supply. Installing the rubber gasket 9 at the lower end of the original fixing plate 8 not only does not affect the fixing effect, but also plays a buffering role, which greatly alleviates the stress caused by the vibration, thereby greatly extending the service life of the module power supply.

[0077] As a specific embodiment of the present invention, the fixing plate 8 is divided into a No. 1 fixing plate 81 and a No. 2 fixing plate 82 which are distributed up and down. The No. 1 fixing plate 81 can slide relative to the No. 2 fixing plate 82. The top plate 4 is provided with a screw hole 811 at the position corresponding to the screw hole of the fixing plate 8.

[0078] The fixing plate 8 of the present invention is divided into a fixing plate No. 1 81 and a fixing plate No. 2 82 from top to bottom, and the fixing plate No. 1 81 can slide relative to the fixing plate No. 2 82 through the sliding groove of the side wall, and the top plate 4 is provided with a screw hole 811 at the position corresponding to the screw hole of the fixing plate 8. In this way, when multiple module power supplies are needed, the upper module power supplies are superimposed together through the screw hole 811 of the bottom plate 3 and the threaded connection of the protective shell 61 to play a fixing role. Due to mechanical vibration generated during use, the threaded hole 32 and the thread of the protective shell 61 will move, resulting in a poor fixing effect. The fixing plate 8 is rotated downward, and the fixing plate No. 1 81 is pulled out, and the threaded opening on the fixing plate 8 is aligned with the screw hole 811 on the side wall of the top plate 4, and fixed with bolts. This can improve the stability between the module power supplies, avoid the problem of poor fixing effect caused by mechanical vibration, and thus ensure the normal use of the module power supply.

[0079] Working principle: The wide voltage output industrial module power supply of the present invention includes an existing power module 1 and a mounting base 2, the mounting base 2 is two mounting columns distributed front and back, and also includes a shell component connected to both the power module 1 and the mounting base 2, and the shell component is connected to a heat dissipation component; compared with the existing wide voltage output industrial module power supply, a fan is installed on the outside of the power module 1 to blow air to the power module 1 through forced air cooling. Although this can achieve heat dissipation and cooling of the working power module 1, the form of fan cooling is relatively simple, and it is simply to blow air to the power module 1 through the fan, so that the heat dissipation and cooling effect that can be achieved is not good; first, the shell component of the present invention can play a role of stable support for the power module 1, firmly install the power module 1 in the shell component, and can enrich the packaging shell of the existing module power supply, so that the shell is no longer so simple, and then the power module 1 is cooled and cooled by the heat dissipation component connected to the shell component, so as to avoid the continuous heating of the working power module 1, increase the power consumption of the internal components, and thus seriously shorten the service life of the module power supply, so the service life of the module power supply can be greatly extended by the heat dissipation component. The shell assembly of the present invention includes a circular bottom plate 3 connected to a mounting seat 2, a support column 5 is fixedly connected to the upper surface of the bottom plate 3, a circular top plate 4 is fixedly connected to the upper end surface of the support column 5, and the top plate 4 corresponds to the position of the bottom plate 3, the support column 5 connects the top plate 4 and the bottom plate 3, and a space for installing the power module 1 is reserved on the upper surface of the bottom plate 3, so that the power module 1 can be installed on the bottom plate 3, which plays a role of stable support, and the gap formed in the middle of the top plate 4 and the bottom plate 3 arranged up and down provides sufficient heat dissipation space for the working power module 1, although the volume is reduced, the remaining heat dissipation area is sufficient, the side wall is all gaps except for the support column 5 which plays a supporting role, and there will be no problem of reduction of heat dissipation area due to volume reduction, ensuring that the power module 1 can contact the air, has the effect of natural cooling of the air, and plays the effect of preliminary cooling and heat dissipation of the power module 1, and at the same time, when the shell material remains unchanged, the volume of the cylindrical cavity is larger than that of the cubic cavity.The heat dissipation assembly of the present invention includes a heat dissipation motor 6 fixedly connected to the upper surface of the top plate 4, and a heat dissipation plate 7 fixedly connected to the output shaft of the heat dissipation motor 6 is installed between the top plate 4 and the bottom plate 3. When the heat dissipation motor 6 works, the output shaft drives the heat dissipation plate 7 to rotate between the top plate 4 and the bottom plate 3. The heat dissipation plate 7 is formed by a cross fan blade 71 and a circular wall 72 fixedly connected, and an extension wall 721 of the circular wall 72 extends downward to the surface of the bottom plate 3, and the extension wall 721 can slide in the slide groove on the surface of the bottom plate 3. A heat dissipation hole 73 is opened on the extension wall 721 of the heat dissipation plate 7, and a plurality of heat dissipation ports 31 are opened on the surfaces of the bottom plate 3 and the top plate 4 and penetrate the surface. In this way, when the power source heat dissipation motor 6 is working, the output shaft rotates to drive the heat dissipation plate 7 to rotate between the top plate 4 and the bottom plate 3, and the cross fan blade 71 of the heat dissipation plate 7 rotates through the heat dissipation port 31 of the top plate 4 to dissipate the outside Air at normal temperature is sucked in and blown toward the power module 1 installed on the upper surface of the base plate 3 to cool it down, and then discharged through the heat dissipation port 31 of the base plate 3. Due to the rotation of the cross fan blades 71 together with the annular wall 72, air can enter from the side of the wide voltage output industrial module power supply, thereby achieving a cooling effect and accelerating the air flow rate inside the shell assembly. Part of the air enters the heat sink 7 through the heat dissipation holes 73 opened on the surface of the extended wall 721 of the heat sink 7, so that the annular wall 72 not only plays the role of a part of the shell, but also improves the heat dissipation effect, thereby achieving the cooling of the power module 1 together, avoiding continuous work that causes the temperature of the power module 1 to rise, thereby increasing the power consumption of internal devices, and seriously shortening the service life of the module power supply. The heat dissipation and cooling of the power module 1 by the heat dissipation assembly can greatly extend the service life of the module power supply. The heat dissipation motor 6 of the present invention is covered with a protective shell 61 on the outside, and the protective shell 61 can protect the heat dissipation motor 6. The outer surface of the upper half of the protective shell 61 is provided with threads, and a threaded hole 32 is provided at the center of the bottom plate 3. In this way, the number of module power supplies can be adjusted according to the voltage value requirements of the module power supply. It is only necessary to install the threaded hole 32 of the upper module power supply bottom plate 3 on the protective shell 61 of the lower module power supply through a threaded connection. The operation is simple. Because only the upper half of the protective shell 61 has threads on the surface, a part of the heat dissipation space will be left between the bottom plate 3 of the upper module power supply and the top plate 4 of the lower module power supply. When the heat dissipation plate 7 of the heat dissipation assembly of the upper module power supply is working, the air can still be discharged through the heat dissipation port 31 of the bottom plate 3 to ensure the heat dissipation effect of the upper and lower module power supplies. Similarly, the number of module power supplies can be increased or decreased according to needs.The support columns 5 of the present invention are all triangular in shape. As is known to all, the triangle has the best firmness. As far as a module power supply is concerned, the support column 5 serves to connect and stabilize the top plate 4 and the bottom plate 3. For multiple module power supplies stacked together by threaded connection, the module power supply at the bottom needs to bear all the weight. Therefore, it is most stable to design the support column 5 of the module power supply to be triangular in shape, which can withstand greater pressure and avoid the problem that the support column 5 cannot support due to the weight being too heavy. The caliber of the heat dissipation hole 73 of the present invention is small inside and large outside. The caliber of the heat dissipation hole 73 on the outer wall of the extension wall 721 is larger than that of the inner wall. The air flow rate can be accelerated by reducing the caliber from outside to inside. In addition to the air flow rate formed by the rotation speed of the heat dissipation plate 7, the caliber design of the heat dissipation hole 73 further accelerates the air flow rate, so that the air strength entering the housing assembly is greater, the heat dissipation effect on the power module 1 is improved, and the temperature rise of the internal components of the power module 1 is reduced, thereby greatly extending the service life of the module power supply. The left and right side walls of the lower surface of the bottom plate 3 of the present invention are fixedly connected with an articulated seat 33, a fixed plate 8 is rotatably connected inside the articulated seat 33, and a limiting plate 331 is fixedly connected to the upper end of the articulated seat 33, the module power supply is installed on the mounting seat 2 through the fixing plate 8, which plays a stabilizing role, and the articulated seat 33 can enable the fixing plate 8 to rotate, and the limiting plate 331 is fixed on the upper end of the articulated seat 33, so that the fixing plate 8 can only rotate downward, and the fixing plate 8 is connected to the mounting seat 2 when necessary. If multiple module power supplies need to be superimposed, the fixing plate 8 of the upper module power supply can be rotated downward and retracted to avoid occupying the usable space series and causing unnecessary scratches. The installation position of the fixing plate 8 and the hinge seat 33 of the present invention is slightly higher than the lower surface of the base plate 3. A rubber gasket 9 is fixedly connected to the lower surface of the fixing plate 8. In some special occasions, the intensity of mechanical vibration is relatively large, which causes the module power supply to vibrate. If the fixing plate 8 is used directly for fixing, it is easy to cause the fixing plate 8 to break due to the strong vibration stress, resulting in the failure of the module power supply. Installing the rubber gasket 9 at the lower end of the original fixing plate 8 not only does not affect the fixing effect, but also plays a buffering role, which greatly alleviates the stress caused by the vibration, thereby greatly extending the service life of the module power supply.The fixing plate 8 of the present invention is divided into a fixing plate No. 1 81 and a fixing plate No. 2 82 from top to bottom, and the fixing plate No. 1 81 can slide relative to the fixing plate No. 2 82 through the sliding groove of the side wall, and the top plate 4 is provided with a screw hole 811 at the position corresponding to the screw hole of the fixing plate 8. In this way, when multiple module power supplies are needed, the upper module power supplies are superimposed together through the screw hole 811 of the bottom plate 3 and the threaded connection of the protective shell 61 to play a fixing role. Due to mechanical vibration generated during use, the threaded hole 32 and the thread of the protective shell 61 will move, resulting in a poor fixing effect. The fixing plate 8 is rotated downward, and the fixing plate No. 1 81 is pulled out, and the threaded opening on the fixing plate 8 is aligned with the screw hole 811 on the side wall of the top plate 4, and fixed with bolts. This can improve the stability between the module power supplies, avoid the problem of poor fixing effect caused by mechanical vibration, and thus ensure the normal use of the module power supply.
