Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0057] The core of the utility model is to provide a single crystal power supply module.

The module is small in size, light in weight, and has a reasonable layout.

[0058] Please refer to Figure 1 A single crystal power module includes a box 1, an output component 2, a water cooling component 3, a high-frequency transformer 4, an output inductor 5, an input component 6, a Hall 7, a support capacitor 8, an output rectifier diode 9, an inverter module group 10 and a DC blocking capacitor 11.

[0059] Specifically, a water cooling component 3 is provided inside the box body 1, and an output component 2 fixed to the water cooling component 3 is provided at one end of the box body 1, so that the output component 2 can be effectively cooled. The high-frequency transformer 4 is fixed to one side of the water cooling component 3 and a cooling liquid channel is provided in the cavity of the high-frequency transformer 4, so that the heat generated during its operation can be transferred to the outside of the module through the cooling liquid channel and the cooling water inside the water cooling component 3, thereby reducing the temperature rise in the module and avoiding shortening its service life due to excessive temperature rise. The output inductor 5 is connected in series with the end of the high-frequency transformer 4 and fixed to the water cooling component 3, so that the heat generated during its operation can be transferred to the outside of the module through the high-frequency transformer 4 and the cooling water inside the water cooling component 3. The input component 6 is provided on the other side of the water cooling component 3, and the heat generated during the operation of the input component 6 can be transferred to the outside of the module through the water cooling component 3. The capacitor 7 is arranged on the output component 2 to detect the size of the output current. The support capacitor 8 is fixed on the water cooling component 3 to absorb the low-voltage ripple in the electrical circuit. The heat generated by the support capacitor 8 during operation can be taken away by the water cooling component 3. The output rectifier diode 9 is arranged on one side of the high-frequency transformer 4, which is convenient for outputting the heat of the rectifier diode 9, shortening the connection path between the output rectifier diode 9 and the high-frequency transformer 4, reducing the output circuit connection impedance and the peak burr voltage, which is beneficial to reducing the output circuit voltage drop, thereby improving the power supply efficiency. The inverter module group 10 is fixed on the water cooling component 3, and the inverter module group 10 is connected to the input component 6 and is arranged on the same side of the water cooling component 3 as the input component 6. The heat generated by the inverter module during operation is transmitted to the outside of the module through the water cooling component 3. The DC blocking capacitor 11 is fixed on the bottom plate of the box body 1 and is connected in series with the inverter module group 10.

[0060] The single crystal power module configured in the above manner can transfer the heat generated by the various components inside the module during operation to the outside of the module through the water cooling component 3 and the high-frequency transformer 4, thereby reducing the temperature rise inside the module, avoiding shortening its service life due to excessive temperature rise, and improving the heat dissipation effect of the module. The output rectifier diode 9 is directly installed on the side of the high-frequency transformer 4, which is convenient for the heat dissipation of the output rectifier diode 9, shortens the connection path between the output rectifier diode 9 and the high-frequency transformer 4, reduces the output circuit connection impedance and the peak burr voltage, and is conducive to reducing the output circuit voltage drop, thereby improving the power supply efficiency. The module is small in size, light in weight, and has a reasonable layout.

[0061] In the above embodiment, the water cooling assembly 3 includes a first water cooling row 31 and a second water cooling row 32. The first water cooling row 31 is arranged inside the box body 1 and extends along the length direction of the box body 1. The second water cooling row 32 is arranged inside the box body 1 and parallel to the first water cooling row 31. The supporting capacitor 8 is fixed to the first water cooling row 31.

[0062] It should be noted that cooling water circulates inside the first water-cooling row 31 and the second water-cooling row 32. The cooling water of the first water-cooling row 31 and the second water-cooling row 32 outputs the heat generated by the components inside the module during operation to the outside of the module, thereby reducing the temperature rise inside the module and avoiding shortening the service life of the components due to excessive temperature rise. The heat generated by the support capacitor 8 during operation can be taken away by the first water-cooling row 31.

[0063] Among them, the second water-cooling row 32 is installed at the tail of the box body 1, and a quick-pull water nozzle is designed on it, which serves as the inlet and outlet of the cooling water inside the entire module. The water path of the second water-cooling row 32 and the first water-cooling row 31 are connected through a water pipe, and the first water-cooling row 31 is connected to the cavity water path of the high-frequency transformer 4 through a water pipe. The water path inside the cavity of the high-frequency transformer 4 is short-circuited and connected, thus forming a circulating cooling water path.

[0064] Furthermore, one side of the high-frequency transformer 4 is isolated from the side of the first water-cooling row 31 by a heat dissipation silicone cloth and fixed by bolts, so that the heat generated during its operation is transmitted to the outside of the module through the cooling water inside the first water-cooling row 31, reducing the temperature rise inside the module and avoiding shortening its service life due to excessive temperature rise. The high-frequency transformer 4 is connected to the input end of the output rectifier diode 9 through a conductive bar, and the output rectifier diode 9 is directly installed on one side of the high-frequency transformer 4. Therefore, the conductive bar connection position is close and the input is symmetrical, which can effectively reduce the connection loop impedance and reduce the loop loss. The short-distance connection between the high-frequency transformer 4 and the output rectifier diode 9 can effectively control the peak glitch voltage amplitude on the output rectifier diode 9 to reduce the tube voltage drop of the output rectifier diode 9, thereby improving the power supply efficiency and reducing the temperature rise inside the module.

[0065] On the basis of the above embodiment, the end of the high-frequency transformer 4 is connected in series with one end of the output inductor 5, and the other end of the output inductor 5 is connected to the first water-cooling row 31, so that the heat generated during its operation can be transferred to the outside of the module through the cooling water inside the high-frequency transformer 4 and the cooling water inside the first water-cooling row 31, thereby reducing the temperature rise inside the module and avoiding shortening its service life due to excessive temperature rise.

[0066] In the above case, the output component 2 includes a first output row 21 and a second output row 22. The first output row 21 is fixed to one side of the first water-cooling row 31 and is arranged through one end of the box body 1. The Hall 7 is installed on the first output row 21 to facilitate the detection of the total current inside the module and to control the output current of the module.

[0067] The second output row 22 is fixed to one side of the second water-cooling row 32 and is disposed through one end of the housing 1 .

[0068] It can be understood that the first output row 21 and the second output row 22 are fixed on the first water-cooling row 31 and the second water-cooling row 32 respectively, and the heat on the first output row 21 and the second output row 22 is taken away by the cooling water inside the first water-cooling row 31 and the second water-cooling row 32.

[0069] Furthermore, a filter capacitor 12 is provided between the first water-cooling row 31 and the second water-cooling row 32 , and the filter capacitor 12 is connected on top of the first water-cooling row 31 and the second water-cooling row 32 .

[0070] It should be noted that the filter capacitor 12 is fixed on the PCB board by welding capacitors, and the conductive input side of the filter capacitor 12 is fixed between the first water-cooling row 31 and the second water-cooling row 32 by bolts. The heat generated by the filter capacitor 12 during operation can be transferred to the outside of the module through the cooling water inside the first water-cooling row 31 and the second water-cooling row 32, thereby reducing the temperature rise inside the module and avoiding shortening its service life due to excessive temperature rise.

[0071] In the above embodiment, the input component 6 includes an incoming terminal 61, a rectifier bridge 62 and a fuse 63. The incoming terminal 61 is arranged at the end of the box body 1 and is arranged at the same end of the box body 1 as the first output row 21. The rectifier bridge 62 is fixed to the first water-cooling row 31. One end of the fuse 63 is arranged at the first output row 21, and the other end of the fuse 63 is connected to the rectifier bridge 62.

[0072] It can be understood that the incoming line terminal 61 is installed at the tail of the box 1 and is electrically connected to the incoming line of the fuse 63. One end of the fuse 63 is fixed on the input side of the rectifier bridge 62, and the other end is fixed on the first output row 21 through an insulating column. The incoming line is at the tail of the module, which is convenient for the later maintenance and use of the module. The fuse 63 is installed on the rectifier bridge 62 to reduce electrical connection points and reduce failure points.

[0073] Among them, the rectifier bridge 62, the support capacitor 8, and the inverter module group 10 are connected by bolts from back to front in sequence and fixed on the side of the first water-cooling row 31, so that the heat generated during its operation can be transferred to the outside of the module through the cooling water inside the first water-cooling row 31, reducing the temperature rise of the module and avoiding shortening its service life due to excessive temperature rise. The support capacitor 8 is arranged between the rectifier bridge 62 and the inverter module group 10, which is more conducive to filtering out the pulsating ripple after the bridge rectification, and maintaining the DC bus voltage stable input to the negative output end of the rectifier bridge 62 and then input to the support capacitor 8 and the negative end of the inverter module group 10.

[0074] On the basis of the above embodiment, the positive output end of the rectifier bridge 62 is connected in series with a smoothing inductor 12 , and the smoothing inductor 12 is fixed on the bottom plate of the box body 1 .

[0075] It should be noted that the positive output end of the rectifier bridge 62 is connected in series with a smoothing inductor 13, which is fixed to the bottom plate of the box body 1 by bolts. The smoothing inductor 13 is a heat-generating component, and its installation position slightly away from the rectifier bridge 62 is beneficial to the overall heat dissipation of the module and reduces the temperature rise of the module.

[0076] In the above embodiment, the positive output end of the rectifier bridge 62 is connected to the support capacitor 64 and the inverter module group 10 through the first conductor, and the negative output end of the rectifier bridge 62 is connected to the support capacitor 64 and the inverter module group 10 through the second conductor.

[0077] It can be understood that a closed loop is formed between the rectifier bridge 62, the support capacitor 64, and the inverter module group 10 through the first conductor and the second conductor, and the support capacitor 64 is used to absorb the low-voltage ripple in the electrical circuit.

[0078] As a preferred embodiment, the inverter module group 10 includes a first inverter module 101 and a second inverter module 102. The first inverter module 101 is fixed to the first water cooling row 31 and a DC blocking capacitor 11 is connected in series at the output end. The second inverter module 102 is arranged in parallel with the first inverter module 101.

[0079] It should be noted that the output end of the first inverter module 101 is connected in series with a DC blocking capacitor 11 and is connected to a high-frequency transformer 4, the output end of the second inverter module 102 is connected to the high-frequency transformer 4, and the first inverter module 101 and the second inverter module 102 are both fixed on the first water-cooling row 31. The heat generated during the operation of the first inverter module 101 and the second inverter module 102 is taken away by the cooling water inside the high-frequency transformer 4 and the first water-cooling row 31.

[0080] The DC blocking capacitor 11 is composed of one or more capacitors connected in parallel, and there is no limitation on this as long as the above technical effect can be achieved.

[0081] In the above situation, the positive and negative input terminals of the first inverter module 101 and the second inverter module 102 are respectively connected in parallel with two absorption capacitors 14 , and the output terminals of the first inverter module 101 and the second inverter module 102 are connected to the high-frequency transformer 4 through a third conductor.

[0082] It can be understood that the positive and negative input terminals of the first inverter module 101 and the second inverter module 102 are respectively connected in parallel with two absorption capacitors 14, and the absorption capacitors 14 are connected nearby, which can effectively absorb the peak voltage, protect the first inverter module 101 and the second inverter module 102, and extend their service life. The output terminals of the first inverter module 101 and the second inverter module 102 are connected to the high-frequency transformer 4 through the third conductor, and the heat generated by the first inverter module 101 and the second inverter module 102 during operation is taken away by the cooling water inside the high-frequency transformer 4.

[0083] In the above embodiment, the output end of the output rectifier diode 9 is connected to the second output row 22 via a bus bar.

[0084] It should be noted that the output end of the output rectifier diode 9 is connected to the second output row 22 through a bus, and the second output row 22 is fixed to the second water-cooling row 32 with bolts. The heat generated when a large current passes through the second output row 22 can be transferred to the outside of the module through the cooling water inside the second water-cooling row 32, thereby reducing the temperature rise inside the module and increasing the current carrying capacity of the second output row 22.

[0085] In summary, the single crystal power supply module provided by the utility model can transfer the heat generated by the various components inside the module during operation to the outside of the module through the water cooling component 3 and the high-frequency transformer 4, thereby reducing the temperature rise inside the module, avoiding shortening its service life due to excessive temperature rise, and improving the heat dissipation effect of the module. The output rectifier diode 9 is directly installed on the side of the high-frequency transformer 4, which is convenient for the heat dissipation of the output rectifier diode 9, shortens the connection path between the output rectifier diode 9 and the high-frequency transformer 4, reduces the output circuit connection impedance and the peak burr voltage, and is conducive to reducing the output circuit voltage drop, thereby improving the power supply efficiency. The module is small in size, light in weight, and has a reasonable layout.
