Description

Technical Field

[0001] The present invention relates to the technical field of synchronous rectification power supplies, in particular to a synchronous rectification power supply assembly structure. Background Art

[0002] Synchronous rectification power supply assemblies are widely used in electronic equipment to provide stable and reliable power output for various electrical components and assemblies. To ensure that the internal components maintain a suitable operating temperature during operation, these power supply assemblies typically require a cooling system to cool the power supply. When the components within the power supply generate heat, a circulating cooling medium (such as coolant) must be used to remove the heat from the heat-generating components, thereby maintaining normal system operation and stable performance.

[0003] However, in existing cooling methods, blade-type or similar pumps that directly contact the liquid medium are mostly used as driving devices. This type of traditional pump has the following problems in actual use: First, the blades are in direct contact with the coolant, which may introduce mechanical friction debris or impurities, causing the coolant to be contaminated during the circulation process, reducing the quality and service life of the coolant, and leading to an increase in the frequency of subsequent maintenance and replacement. Second, the flow regulation of traditional pumps often requires replacing the motor or performing complex debugging of the entire transmission mechanism, and it is impossible to flexibly control the coolant flow rate without changing the motor power. For the synchronous rectifier power supply assembly structure with a compact internal structure and strict requirements, the contamination risk and inconvenient flow regulation of traditional pumps make it difficult to meet the requirements of modern electronic equipment for refined heat dissipation and easy maintenance. Summary of the Invention

[0004] In response to the deficiencies of the prior art, the present invention provides a synchronous rectifier power supply assembly structure that can achieve the goal of eliminating the need for direct contact between the coolant and the pump body, flexibly adjusting the coolant flow rate according to the system's heat dissipation requirements, and facilitating the replacement and maintenance of the cooling medium.

[0007] The mounting plate array has symmetrical flow channels inside, and heat dissipation holes are evenly opened on the rear side of the mounting plate surface. The heat dissipation holes are perpendicular to the axis of the flow channels. A plurality of the heat dissipation holes are placed outside the power supply body. The heat dissipation holes are used to cool the fluid inside the flow channels. A cooling liquid temporary storage mechanism is installed at the rear end between the two mounting plates. The cooling liquid temporary storage mechanism connects the flow channels on both sides to each other.

[0008] A reflux mechanism is provided on the front side of the power supply body, and the reflux mechanism includes a fixing seat fixed to the inner wall of the end plate and a connecting plate fixed to the front ends of the two mounting plates. Two hoses are connected between the two connecting plates. The hoses are arranged in a U shape, and the two ends of the hoses are respectively connected to the front ends of the flow channel;

[0009] The power source body is equipped with an extrusion flow mechanism, which includes a rotating shaft rotating on the lower surface of the power source body. The rotating shaft is placed at the center of the two hose bends, and an extrusion force control mechanism is also installed inside the rotating shaft.

[0010] Furthermore, the coolant temporary storage mechanism includes a temporary storage tank, which is hollow inside. A sealing plug is screwed on the end of the temporary storage tank, and the sealing plug seals the opening of the temporary storage tank. Docking pipes are symmetrically arranged on both sides of the temporary storage tank. The docking pipe structure is L-shaped, and the ends of the docking pipes are respectively connected to the rear end of the flow channel.

[0011] Furthermore, the surface of the fixing seat is provided with an arc surface, the center of the arc surface coincides with the axis of the rotating shaft, and two concave surfaces are provided inside the arc surface, and the two hoses are laid along the concave surfaces respectively.

[0012] Furthermore, a fixing block is provided on the surface of the rotating shaft, the fixing block corresponds to the position of the hose, the fixing block is in a triangular structure, and extension plates are provided outwardly on three sides of the fixing block.

[0013] Furthermore, a sliding sleeve is installed on the end surface of the extension plate, and an extrusion roller is rotatably installed on the end of the sliding sleeve. The axis of the extrusion roller is vertically arranged, and the surface of the extrusion roller is provided with an arc surface that is adapted to the hose. The extrusion roller squeezes the area of ​​the hose placed inside the concave surface.

[0014] Furthermore, a first gear is provided on the surface of the rotating shaft, the first gear is placed above the inside of the power supply body, a motor is fixed on the upper surface of the shell, a second gear is installed on the output shaft of the motor, and the second gear is meshed with the first gear.

[0015] Furthermore, the shaft curved surface is evenly provided with three open grooves along its axis, the open grooves correspond one to one with the three side surfaces of the fixed block, an inner sliding hole is vertically provided inside the shaft, and the extrusion force control mechanism includes a bidirectional screw rotatably installed inside the inner sliding hole.

[0016] Furthermore, a knob is provided on the top of the bidirectional screw, and the knob is placed above the shell.

[0017] Furthermore, three connecting rods are evenly hinged on the side of the control block, and the connecting rods pass through the open slots. The ends of the three connecting rods facing away from the control block are respectively hinged on three sliding sleeves.

[0018] The present invention provides a synchronous rectification power supply assembly structure, which has the following beneficial effects:

[0019] This technical solution utilizes an extrusion-type fluid delivery mechanism within the synchronous rectifier power supply assembly, effectively avoiding the contamination risks associated with direct coolant contact with conventional vane-type pumps. Thanks to the contactless transmission between the extrusion roller and the hose, the coolant is no longer susceptible to blade abrasion or metal particles during circulation, significantly improving its cleanliness and service life. This structure also reduces the maintenance costs and cycle time associated with frequent coolant changes, ensuring the power supply maintains a high-quality heat dissipation environment during extended operation.

[0020] This technical solution achieves the goal of flexibly adjusting the coolant flow rate without changing the motor's output power by incorporating an extrusion force control mechanism within the rotating shaft. Through a multi-layered transmission system consisting of a knob, bidirectional screw, control block, connecting rod, sleeve, and extrusion roller, the extrusion force can be quickly fine-tuned according to internal temperature fluctuations within the power supply, thereby precisely controlling the coolant delivery rate. This flexible and adjustable flow management method ensures efficient and stable cooling within the power supply under varying heat dissipation requirements, improving the overall operational reliability and adaptability of the power supply.

[0021] This technical solution forms a comprehensive coolant circulation path within the power supply, consisting of a temporary storage tank, docking pipes, flow channels, heat dissipation holes, hoses, and an extrusion mechanism. Through a rational piping layout and the coordination of heat dissipation holes on the mounting plate, the flowing coolant efficiently removes internal heat and rapidly cools the outside of the mounting plate. The provision of a coolant temporary storage tank and sealing plug facilitates coolant replacement and maintenance, avoiding the difficulty of cleaning or replacing traditional cooling structures, thereby significantly improving the power supply's operational stability, maintainability, and service life.

[0037] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1:

[0039] See Figure 1-9 A synchronous rectification power supply assembly structure includes a power supply body 1, an end plate 11 is provided on the front end surface of the power supply body 1, two mounting plates 12 are symmetrically fixed inside the power supply body 1, the two end plates 11 pass through the rear end surface of the power supply body 1, and a transformer 13 is installed on the surface of the two mounting plates 12 facing away from each other. The top of the power supply body 1 is covered with a shell 3, and the shell 3 protects the internal equipment of the power supply body 1; in the above structure, the power supply body 1, the end plate 11, the mounting plate 12, the transformer 13 and the shell 3 cooperate with each other to achieve effective fixation and protection of the internal components, so as to avoid the internal of the power supply body 1 being affected by the external environment during operation. Energy fluctuations; since the synchronous rectification power supply assembly structure needs to ensure the heat dissipation and stability of the internal components of the power supply body 1 during efficient operation, it is necessary to use a reasonably configured coolant circulation to efficiently remove the internally generated heat, so that the internal components of the power supply body 1 can maintain a suitable working temperature during long-term operation; in this structure, the subsequent extrusion flow mechanism and the coolant temporary storage mechanism can be used to cooperate to achieve an internal driving mode without direct contact with the coolant, reducing the risk of coolant contamination to a low level, and the coolant flow rate can be flexibly adjusted according to the operating status of the power supply body 1, thereby ensuring more refined and flexible heat management inside the power supply body 1.

[0040] Flow channels 14 are symmetrically opened inside the mounting plate 12, and heat dissipation holes 15 are evenly opened on the rear side of the surface of the mounting plate 12. The heat dissipation holes 15 are perpendicular to the axis of the flow channels 14. Multiple heat dissipation holes 15 are all located on the outside of the power supply body 1. The heat dissipation holes 15 are used to cool the fluid inside the flow channels 14. A cooling liquid temporary storage mechanism 2 is installed at the rear end between the two mounting plates 12. The cooling liquid temporary storage mechanism 2 connects the flow channels 14 on both sides to each other. At this location, the arrangement of the mounting plates 12, the flow channels 14 and the heat dissipation holes 15 allows the coolant to dissipate excess heat through the heat dissipation holes 15 when flowing inside the flow channels 14, thereby improving the heat dissipation efficiency inside the power supply body 1. The presence of the cooling liquid temporary storage mechanism 2 allows the coolant on both sides of the flow channels 14 to be connected to each other, thereby forming a complete cooling liquid circulation path inside the power supply body 1. Through this fluid circulation structure, the power supply body 1 can transfer heat to the surface of the mounting plate 12 during operation and achieve efficient cooling through convection and heat dissipation, thereby meeting the requirements of the synchronous rectifier power supply assembly structure for stable and reliable operation.

[0041] A reflux mechanism 4 is provided on the front side of the interior of the power supply 1. The reflux mechanism 4 includes a fixing seat 41 fixed to the inner wall of the end plate 11 and a connecting plate 44 fixed to the front ends of the two mounting plates 12. Two hoses 45 are connected between the two connecting plates 44. The hoses 45 are arranged in a U-shape, and the two ends of the hoses 45 are respectively connected to the front ends of the flow channel 14. In this structure, the end plate 11, the fixing seat 41, the connecting plate 44, the hoses 45, and the flow channel 14 at the front end are connected front to back to form a complete circulation path. The hoses 45 achieve the diversion and recirculation of the coolant in the U-shaped arrangement, which can form a smooth flow inside, so that the heat dissipation process inside the power supply body 1 is more balanced and stable. In this configuration where no blades directly contact the coolant, the risk of the coolant being contaminated by solid impurities can be greatly reduced, thereby meeting the requirements of the synchronous rectifier power supply assembly structure for the service life and quality of the coolant.

[0042] 1 is equipped with an extrusion flow mechanism 5, which includes a rotating shaft 51 rotating on the lower surface of the inner part of the power supply body 1. The rotating shaft 51 is located at the center of the bend of the two hoses 45. An extrusion force control mechanism 6 is also installed inside the rotating shaft 51. In this mechanism, the power supply body 1, the extrusion flow mechanism 5, the rotating shaft 51 and the extrusion force control mechanism 6 all work together to implement non-contact extrusion of the hoses 45 through the mechanical structure inside the extrusion flow mechanism 5, so that the coolant flows inside the hoses 45 without directly contacting the surface of the driving components. This structure effectively avoids the contamination problem of traditional vane-type pump bodies, and can flexibly control the coolant flow rate by changing the relative distance between components on the rotating shaft 51 through the extrusion force control mechanism 6, thereby meeting the cooling requirements under different temperature conditions inside the power supply body 1, so that the synchronous rectifier power supply assembly structure maintains stable and efficient operation during long-term operation.

[0043] See Figure 1 and Figure 9 The cooling liquid temporary storage mechanism 2 includes a temporary storage tank 21, which is hollow inside. A sealing plug 23 is screwed on the end of the temporary storage tank 21, and the sealing plug 23 seals the opening of the temporary storage tank 21. A docking pipe 22 is symmetrically arranged on both sides of the temporary storage tank 21. The docking pipe 22 has an L-shaped structure, and the ends of the docking pipe 22 are respectively connected to the rear end of the flow channel 14; at this point, the coordinated arrangement of the temporary storage tank 21, the sealing plug 23 and the docking pipe 22 is conducive to establishing a complete cooling liquid storage and management system inside the power supply body 1; by injecting appropriate cooling liquid into the temporary storage tank 21 and sealing it with the sealing plug 23, the cooling liquid can be easily replaced or replenished in subsequent operations; the L-shaped structure of the docking pipe 22 enables the cooling liquid to be smoothly connected to the flow channel 14 and ensures that the cooling liquid continues to circulate inside the power supply body 1; this split cooling liquid storage and delivery system helps to quickly adjust the flow rate according to the actual heat dissipation needs inside the power supply body 1, thereby improving the maintenance convenience and practicality of the synchronous rectifier power supply assembly structure.

[0044] See Figure 5-6 , an arc surface 42 is provided on the surface of the fixing seat 41, the center of the arc surface 42 coincides with the axis of the rotating shaft 51, and two concave surfaces 43 are provided inside the arc surface 42, and two hoses 45 are laid along the concave surfaces 43 respectively; in this detail, the precise cooperation between the fixing seat 41, the arc surface 42 and the concave surface 43 ensures that the hose 45 presents a stable geometric layout inside the power supply body 1; through the coincidence of the arc surface 42 and the axis of the rotating shaft 51, the extrusion roller can form a uniform periodic extrusion on the hose 45 when the rotating shaft 51 rotates, thereby maintaining the orderly circulation of the coolant without direct contact with the liquid; through this structure, a compact and efficient coolant delivery route can be formed inside the power supply body 1, thereby further reducing the possibility of the coolant being contaminated by impurities and meeting the high requirements of the synchronous rectifier power supply assembly structure for cooling efficiency.

[0045] See Figure 5-8 A fixed block 55 is provided on the surface of the rotating shaft 51, and the position of the fixed block 55 corresponds to the position of the hose 45. The fixed block 55 is a triangular structure, and extension plates 56 are provided outward on the three sides of the fixed block 55; here, the rotating shaft 51, the fixed block 55 and the extension plate 56 together constitute the core component that can drive the subsequent extrusion mechanism to operate when the rotating shaft 51 rotates; the corresponding position arrangement of the fixed block 55 and the hose 45 ensures that the movement path of the extension plate 56 is accurately aligned with the area where the hose 45 is located when the rotating shaft 51 rotates, so that the extrusion roller can achieve high-precision extrusion; this precise mechanical matching structure effectively ensures the continuous circulation of the coolant inside the power supply body 1 and the flexible adjustment of the flow rate by controlling the extrusion degree, providing highly adaptable heat dissipation performance for the synchronous rectifier power supply assembly structure.

[0046] See Figure 5-8 , a sliding sleeve 57 is installed on the end surface of the extension plate 56, and an extrusion roller 58 is rotatably installed on the end of the sliding sleeve 57. The axis of the extrusion roller 58 is set vertically, and an arc surface 42 is opened on the surface of the extrusion roller 58 to match the hose 45. The extrusion roller 58 squeezes the area of ​​the hose 45 located inside the concave surface 43; here, the combined action of the extension plate 56, the sliding sleeve 57 and the extrusion roller 58 enables the hose 45 to be accurately and controllably squeezed during the rotation of the rotating shaft 51; the extrusion roller 58 uses the contact interface between the arc surface 42 and the hose 45 to form a continuous flow of coolant inside the hose 45 and adjust the squeezing force by changing the extension length of the sliding sleeve 57 to control the flow rate of the coolant; this design forms a precise control path for the cooling performance inside the power supply body 1, which meets the requirements of the background technology for reducing pollution, improving cooling efficiency, extending the service life of the coolant and flexibly adjusting the flow rate.

[0047] See Figure 7-8A first gear 52 is provided on the surface of the rotating shaft 51, and the first gear 52 is placed above the inside of the power supply body 1. A motor 53 is fixed to the upper surface of the shell 3, and a second gear 54 is installed on the output shaft of the motor 53. The second gear 54 and the first gear 52 are meshed with each other; through this gear transmission structure, the power output by the motor 53 can be transmitted to the first gear 52 via the second gear 54 and further drive the rotating shaft 51 to rotate; the cooperation between the motor 53 and the rotating shaft 51 enables the extrusion flow mechanism 5 to periodically squeeze the hose 45, so that the coolant inside the power supply body 1 can circulate efficiently without direct contact with the blades; this transmission method ensures the stable heat dissipation performance of the power supply body 1 while reducing the chance of the coolant being contaminated by the outside world, improves the convenience of maintenance of the internal transmission mechanism and provides a basis for adjusting the flow according to different temperature conditions.

[0048] See Figure 7-8 The curved surface of the rotating shaft 51 is evenly provided with three open grooves 59 along its axis, and the open grooves 59 correspond to the three side surfaces of the fixed block 55 one by one. An inner sliding hole 510 is vertically provided inside the rotating shaft 51, and the extrusion force control mechanism 6 includes a bidirectional screw 61 rotatably installed inside the inner sliding hole 510; in this structure, the rotating shaft 51 forms a precise match with the open groove 59, the inner sliding hole 510 and the bidirectional screw 61; by rotating the bidirectional screw 61, the position of the control block can be fine-tuned, and the adjustment is transmitted to the position of the extrusion roller through the subsequent structure, so that the extrusion force of the extrusion roller and the distance between the hose 45 can be accurately controlled, thereby flexibly controlling the coolant flow rate to meet the heat dissipation requirements of the power supply body 1 under different working conditions; this design is consistent with the background technology's requirement to adjust the flow without changing the motor power, and provides higher adjustment convenience and maintainability for the synchronous rectifier power supply assembly structure.

[0049] See Figure 8 A knob 62 is provided on the top of the bidirectional screw 61, and the knob 62 is placed above the shell 3. Two control blocks 63 are slidably installed inside the inner sliding hole 510, and the two control blocks 63 are respectively screwed on different thread surfaces of the bidirectional screw 61; here, the bidirectional screw 61, the knob 62 and the control block 63 together constitute a core mechanism that can adjust the extrusion force manually or automatically through the controller and the sensor; by rotating the knob 62, the relative position of the bidirectional screw 61 to the control block 63 can be changed, thereby indirectly changing the extrusion force of the extrusion roller on the hose 45; this technical solution realizes high-efficiency cooling control that is flexibly adjusted from the outside inside the power supply body 1, reduces maintenance difficulty and ensures that the power supply body 1 can quickly adjust the internal coolant flow under different heat dissipation requirements.

[0050] See Figure 7-8, three connecting rods 64 are evenly hinged on the side of the control block 63, and the connecting rods 64 pass through the open slot 59. The ends of the three connecting rods 64 facing away from the control block 63 are respectively hinged on the three sliding sleeves 57; in this structure, the control block 63, the connecting rod 64 and the sliding sleeve 57 form a complete force transmission path; by adjusting the upper and lower positions of the control block 63, the angle change of the connecting rod 64 can be accurately controlled and the extension amount of the sliding sleeve 57 can be affected, thereby indirectly changing the contact pressure between the extrusion roller 58 and the hose 45 and the flow rate of the coolant in the hose 45; this mechanical linkage relationship can reduce the maintenance difficulty through a fully mechanical adjustment method while meeting the above-mentioned background technology of flexible adjustment of the coolant flow rate and reduction of pollution; this layer-by-layer transmission process from the knob 62 to the bidirectional screw 61, the control block 63, the connecting rod 64, and then to the sliding sleeve 57 and the extrusion roller 58 enables the internal cooling mechanism of the power supply body 1 to quickly adapt to and maintain high-performance heat dissipation under different working conditions, thereby laying the foundation for the stable operation of the synchronous rectifier power supply assembly structure.

[0051] Example 2:

[0052] Review of beneficial effects: This technical solution uses an extrusion-type fluid delivery mechanism to replace the traditional vane-type pump body, so that the coolant does not come into direct contact with the blades during the delivery process, thereby reducing impurity contamination caused by mechanical wear and extending the service life of the coolant.

[0053] Example description: In this example, a high temperature resistant silicone hose (model: HT-SG- The coolant used is industrial-grade corrosion- and rust-resistant coolant (Model: CL-789), with an initial purity of at least 99.9%. The extrusion roller is constructed of 304 stainless steel and has a high-precision polished surface. The shaft, extension plate, and sleeve are all constructed of a nickel-based alloy to ensure long life and high precision. Test conditions were an ambient temperature of 25°C, a relative humidity of 50%, and a rated internal heat source of 500W.

[0054] In a traditional vane pump system, after 1,000 hours of operation, the metal ion concentration in the coolant can increase to over 50 ppm, with significant particulate impurities (average particle size of approximately 5 μm). However, the extrusion-type conveying method used in this solution produces no additional particles due to the absence of blade cutting or wear.

[0055] Through experimental comparison, this embodiment sets 5 sets of running time comparison data (see Table 1):

[0056] Table 1: Comparative test data of squeeze-type delivery mechanism and vane-type pump body (coolant purity comparison)

[0057]

[0058] From the data, it can be seen that the coolant of this technical solution still maintains high purity after long-term operation, and the impurity content is much lower than that of the traditional solution.

[0059] Related formula: In this conveying system, the fluid purity attenuation rate model can be used:

[0060] in:

[0061] D is the purity decay ratio; Ct is the impurity concentration in the coolant at time t; and C0 is the impurity concentration at the initial time. Using this extrusion-type delivery solution, D can be maintained at a level close to 1 (i.e., virtually no decay) after 1000 hours.

[0062] Example 3:

[0063] Review of beneficial effects: Through the extrusion force control mechanism, the coolant flow rate can be flexibly adjusted without changing the motor power to adapt to different heat load requirements inside the power supply body.

[0064] Description of the embodiment: In this embodiment, the diameter of the rotating shaft is 10 mm, and the diameter of the extrusion roller driven by the rotating shaft is 20 mm. When the knob is rotated one circle (360°), the bidirectional screw drives the control block to extend the sleeve 0.2 mm. The hose material and model are the same as above, and the coolant is still CL-789. A standard motor with a motor model of ZM-45 is used as the power source. The output speed of the motor is constantly controlled at 2000 rpm. Without changing the motor power, five sets of extrusion force and flow rate comparisons can be achieved by adjusting the knob. Test conditions: Ambient temperature is 25°C, and the heat source power inside the power supply body can vary from 100W to 500W.

[0065] The flow rate is calculated using the formula Q = v·A, where Q is the flow rate (mL / min), v is the average flow velocity in the tube (m / s), and A is the cross-sectional area (m²). By varying the pressure of the extrusion roller, the cross-sectional area of ​​the hose is controlled, thereby changing the flow rate. The experimentally measured data (see Table 2) yields:

[0066] Table 2: Comparison of different extrusion forces, flow rates and cooling effects

[0067]

[0068] From the data, it can be seen that the flow rate and internal temperature distribution can be changed by simply adjusting the extrusion force control mechanism without changing the motor power.

[0069] Related formula:

[0070] Where d is the actual inner diameter of the hose after extrusion. By controlling the extension of the sleeve to change d, flexible regulation of Q can be achieved.

[0071] Example 4:

[0072] Review of beneficial effects: A complete coolant circulation path consisting of a temporary storage tank, a butt tube, a flow channel, a heat dissipation through-hole, a hose and an extrusion mechanism is formed, which improves the internal heat dissipation efficiency, makes it easier to cool the coolant, and makes maintenance and replacement of the coolant more convenient.

[0073] Description of the embodiment: In this embodiment, the temporary storage tank is made of stainless steel 316L (volume 500mL), the sealing plug is made of silicone rubber (temperature resistance range -50℃~200℃), the butt joint is an L-shaped copper tube (inner diameter 8mm), the flow channel material is aluminum alloy (6061), the number of heat dissipation holes is 20, the through-hole diameter is 2 mm, and they are evenly distributed at the rear end of the installation plate.

[0074] In the experiment, the power supply's heat source was set to 500W, the flow rate was fixed at 400mL / min (achieved through the adjustments in Example 2), and the system was operated continuously for 100 hours at an ambient temperature of 25°C. To compare with a traditional system without a temporary storage tank and heat dissipation through-hole structures, the comparison conditions were that the traditional system only had straight-through pipes without additional through-holes for cooling. The temperatures of key points within the power supply were measured (T1, T2, and T3 represent the temperatures at different internal device locations), and the coolant return temperature was recorded. The data is shown in Table 3:

[0075] Table 3: Comparison of experimental data between temporary storage tank + heat dissipation holes and traditional structure

[0076]

[0077] The results show that the temperature rise of this solution is significantly lower than that of the traditional solution after long-term operation, and the coolant return temperature is also lower, indicating that the coolant circulation path and temporary storage tank help to cool the coolant during the circulation process and maintain system stability.

[0078] Related formula:

[0079] Cooling efficiency can be estimated using the heat balance formula:

[0080] Where m is the coolant mass flow rate (kg / s), c is the specific heat capacity (J / kg·K), and ΔT is the inlet and outlet temperature difference (K). This solution effectively reduces ΔT, making heat removal more efficient at the same flow rate.

[0081] Example 5:

[0082] Review of beneficial effects: The non-contact extrusion drive mode solves the problems of easy contamination of traditional coolant pumps, difficult flow regulation, and inconvenient maintenance, allowing the synchronous rectification power supply assembly structure to maintain high performance and reliability under various working conditions.

[0083] Example Description: In this example, the same equipment was tested under different operating conditions (heat loads of 200W, 350W, 500W, and 650W). The system was maintained in operation for 200 hours at each load without changing the coolant to verify its adaptability and long-term stability. The extrusion mechanism material remained the same, the coolant was CL-789, the hose, temporary storage tank, flow channel, and heat dissipation hole structure remained the same as in Example 3, and the motor power and shaft design were the same as in Example 2. A conventional vane-type pump solution was used as a control group to compare performance differences under different heat loads and long-term operating conditions, including coolant purity, internal temperature, and flow regulation response time.

[0084] Table 4 shows the comparative data after 200 hours under different heat load conditions (five time points were randomly selected for recording):

[0085] Table 4: Long-term multi-operating condition comparison data of non-contact extrusion mode and vane pump mode

[0086]

[0087] Data analysis shows that this technical solution can maintain low coolant contamination levels, more stable internal temperatures, and faster flow regulation response times under various heat load conditions. Compared with traditional vane pumps, it exhibits less performance degradation after long-term operation, is more responsive, and is easier to operate.

[0088] Related formula: The flow response time τ can be used as an evaluation indicator:

[0089] Where ΔQ is the required flow adjustment, and Δt is the time required to complete the adjustment. The τ value in this solution is between 2.0 and 2.6 seconds, significantly better than the 2.0 to 4.0 seconds range of traditional solutions. This metric clearly demonstrates the rapid response characteristics of this solution.

[0090] Working principle: First, screw the sealing plug 23 to open it and inject coolant into the temporary storage tank 21 so that the coolant fills the temporary storage tank 21 and the flow channel 14. When working, the motor 53 can be started to drive the second gear 54 to rotate, and the engagement of the second gear 54 with the first gear 52 drives the rotating shaft 51 to rotate. When the rotating shaft 51 rotates, it can drive the two fixed blocks 55 on its surface to rotate synchronously, so that the extension plate 56 rotates, and then drives the squeezing roller 58 at its end to rotate around the axis of the rotating shaft 51. Since the hose 45 is laid along the concave surface 43 of the inner wall of the arc surface 42, and the rotation axis of the rotating shaft 51 coincides with the center of the inner curved surface of the arc surface 42, the three squeezing rollers 58 can circulate and squeeze the hose 45 when the rotating shaft 51 rotates, so that the coolant inside the hose 45 flows due to the squeezing, and the coolant is transported without contact, thereby preventing the traditional pump body blades from contacting the coolant and causing pollution, thereby improving the service life of the coolant and ensuring the cooling quality.

[0091] When the internal coolant is transported due to extrusion, the coolant will form a circulation flow between the coolant temporary storage mechanism 2, the flow channel 14 and the hose 45 to drive the heat generated by the work inside the power supply body 1. The surface of the mounting plate 12 is not only equipped with a transformer 13 but also with multiple electrical components to transfer the heat to the mounting plate 12, and the heat is taken away by the flowing coolant. When the coolant flows to the rear end of the mounting plate 12, because the rear end of the mounting plate 12 is directly exposed to the air, the internal coolant can be cooled, and the multiple heat dissipation holes 15 on the surface can improve the cooling effect of the coolant. The temporary storage tank 21 and the sealing plug 23 cooperate to facilitate the replacement of the internal coolant, thereby improving the convenience of use.

[0092] During operation, the squeezing force of the squeezing roller 58 on the hose 45 can be adjusted, and then the flow rate of the coolant can be controlled without changing the power of the motor 53. The purpose of changing the flow rate can be met by using an ordinary drive motor. According to the temperature inside the power supply body 1, the knob 62 can be rotated externally to control the rotation of the bidirectional screw 61, and then the two control blocks 63 are controlled to move. When the control block 63 moves, the extension distance of the sleeve 57 can be controlled by the connecting rod 64, and then the distance between the squeezing roller 58 and the axis of the rotating shaft 51 is controlled. When the sleeve 57 extends outward, the squeezing force of the squeezing roller 58 on the hose 45 increases. At this time, the internal coolant flow rate increases, and vice versa. The flow rate decreases. This process can be controlled manually or by the controller in conjunction with the temperature sensor inside the power supply body 1.
