Description

Technical Field

[0001] This invention relates to the field of heat dissipation accessories for pulse power conversion equipment, specifically a heat exchange and heat dissipation structure for pulse power conversion. Background Technology

[0002] A pulse typically refers to a brief, pulsating electrical impulse, often used in electronics, characterized by its waveform, amplitude, width, and repetition frequency. Pulse power conversion devices, such as switches and amplifiers, are prone to generating high temperatures during operation. Cooling fans, due to the device's structure, have limited size and relatively poor heat dissipation in high-temperature environments. Furthermore, external environmental factors can interfere with the internal working environment, and dust and other impurities can adhere to the circuitry, potentially causing malfunctions. Therefore, this paper proposes a heat exchange and cooling structure for pulse power conversion to address these issues. Summary of the Invention

[0003] The purpose of this invention is to provide a heat exchange and heat dissipation structure for pulse power conversion in order to solve the above-mentioned problems.

[0004] The present invention achieves the above objectives through the following technical solution: a heat exchange and heat dissipation structure for pulse power conversion, comprising a heat-absorbing liquid container frame, wherein the opening of the heat-absorbing liquid container frame is sealed to the edge of the square grid cover, and a short pipe is installed on the surface of the cavity in the middle of the square grid cover, wherein a plurality of air outlet channels are provided inside the square grid, and the corresponding part inside the air outlet channels is connected to the inside of the heat absorption promoting component, wherein a suction fan blade is installed on one end of the rotating shaft of the motor located inside the short pipe, and the other end of the rotating shaft of the motor is connected to the drive shaft end of the micro water pump located in the middle of the top of the bottom frame through a transmission rod;

[0005] The outlet and inlet pipes on the micro water pump are connected to the inside of the heat-absorbing liquid container and to several capillary tubes. Several wooden conical shells are distributed in a matrix between the bottom of the heat-absorbing liquid container and the top of the bottom frame. The large-diameter end of the wooden conical shell is connected to the inside of the heat-absorbing liquid container, and the small-diameter end of the wooden conical shell is connected to one end of the six capillary tubes in the same group through six fine holes in the same group.

[0006] Preferably, there are multiple heat-absorbing components, and the multiple heat-absorbing components are immersed in the heat-absorbing liquid in the heat-absorbing liquid container. The heat-absorbing component includes a U-shaped strip and two semi-permeable membranes in the same group. The multiple U-shaped strips are vertically installed at the bottom of the square grid cover, and semi-permeable membranes are sealed on the U-shaped surfaces on both sides of the U-shaped strips. The top edge of the semi-permeable membrane is sealed to the corresponding surface of the bottom of the square grid cover.

[0007] Preferably, several capillary tubes are distributed in a serpentine pattern inside the bottom frame, and multiple circular grooves are matrix-shaped on the top surface of the bottom frame. Six fine holes of the same group are equidistantly opened at the bottom of each circular groove, and the opening of the circular groove is sealed and fixedly connected to the small-diameter end port of the wooden conical shell.

[0008] Preferably, the capillary is made of copper and is fixedly connected to the bottom wall of the bottom frame.

[0009] Preferably, the middle part of the transmission rod is rotatably connected to the middle part of the heat-absorbing liquid loading frame via a sealed bearing, and the upper end of the middle part of the transmission rod is rotatably connected to the middle part of the square grid cover via a sealed bearing.

[0010] Preferably, a three-leaf frame is installed in the middle of the short tube, and the motor is fixedly connected to the hole structure in the middle of the three-leaf frame. A circular mesh is installed at the outer end of the short tube.

[0011] Preferably, the outer end port of the air outlet is located on the side wall of the square grille cover, and the top edge of the square grille cover is connected to the bottom edge of the mesh partition.

[0012] Preferably, the grid partition is located inside the housing of the pulse power exchanger and is connected to the bottom edge of the bottom frame in the external environment at the bottom of the housing, with the bottom of the housing being lower than the height of the bottom frame.

[0013] The beneficial effects of this invention are: by synchronously flowing hot air and heat-absorbing liquid, the stagnation of heat after conduction and exchange is avoided, and the heat is easily conducted and diffused to the outside through several capillaries located in the external environment, achieving the effect of heat dissipation and cooling. Moreover, the cooled heat-absorbing liquid exchanges heat with hot air again. The hot air enters the semi-permeable membrane immersed in the heat-absorbing liquid, which not only prevents the heat-absorbing liquid from seeping out, but also efficiently conducts the heat of the hot air to the heat-absorbing liquid. Furthermore, the fan blades and connecting parts are placed inside the equipment instead of the existing cooling fan which is placed at the external connection to the heat dissipation hole. This ensures the airtightness of the equipment from external interference, and the air inside the equipment can circulate. Attached Figure Description

[0026] Example 1

[0027] Please see Figure 1 and 5As shown, a heat exchange and heat dissipation structure for pulse power conversion includes a heat-absorbing liquid container 7. The opening of the heat-absorbing liquid container 7 is sealed to the edge of the square grid cover 8. A short pipe 4 is installed on the surface of the cavity in the middle of the square grid cover 8. Several air outlets 81 are provided inside the square grid, and the corresponding parts inside the air outlets 81 are connected to the inside of the heat absorption promotion component. A suction fan blade 12 is installed on one end of the shaft of the motor 14 located inside the short pipe 4, and the other end of the shaft of the motor 14 is connected to the drive shaft of the micro water pump 9 located in the middle of the top of the bottom frame 6 through a transmission rod 10.

[0028] The advantage of this is that the hot air inside the pulse power exchanger 1 is drawn into the air outlet duct inside the square grille cover 8 and discharged from the external port of the air outlet duct through several heat absorption components.

[0029] Example 2

[0030] Please see Figure 1 , 3 As shown in Figures 4 and 5, the outlet pipe 91 and inlet pipe 92 on the micro water pump 9 are respectively connected to the interior of the heat-absorbing liquid container 7 and to several capillary tubes 11. Several wooden conical shells 5 are distributed in a matrix between the bottom of the heat-absorbing liquid container 7 and the top of the bottom frame 6. The large-diameter end of the wooden conical shell 5 is connected to the interior of the heat-absorbing liquid container 7, and the small-diameter end of the wooden conical shell 5 is connected to one end of the six capillary tubes 11 in the same group through six fine holes 62 in the same group.

[0031] The advantage of this is that the operating micro water pump 9 circulates the heat-absorbing liquid in the heat-absorbing liquid container 7 through the outlet pipe 91, the inlet pipe 92, several wooden conical shells 5, and several connected capillary tubes 11.

[0032] Example 3

[0033] Please see Figure 2 As shown, there are multiple heat absorption promoting components, and these components are immersed in the heat absorption liquid in the heat absorption liquid container 7. Each heat absorption promoting component includes a U-shaped strip 82 and two semi-permeable membranes 83 in the same group. The multiple U-shaped strips 82 are vertically installed at the bottom of the square grid cover 8, and semi-permeable membranes 83 are sealed and installed on the U-shaped surfaces on both sides of the U-shaped strips 82. The top edge of the semi-permeable membrane 83 is sealed and connected to the corresponding bottom surface of the square grid cover 8.

[0034] The advantage of this is that by allowing hot air to enter between the semi-permeable membranes 83 immersed in the heat-absorbing liquid, it can both prevent the heat-absorbing liquid from seeping out and efficiently transfer the heat of the hot air into the heat-absorbing liquid.

[0035] Example 4

[0036] Please see Figure 3 and4 As shown, several capillaries 11 are serpentinely distributed inside the bottom frame 6, and multiple circular grooves 61 are matrixed on the top surface of the bottom frame 6. Six fine holes 62 of the same group are equidistantly opened at the bottom of each circular groove 61. The opening of the circular groove 61 is sealed and fixedly connected to the small-diameter end port of the wooden conical shell 5. The capillaries 11 are made of copper and are fixedly connected to the bottom wall of the bottom frame 6.

[0037] The advantage of this is that by allowing the hot air and the heat-absorbing liquid to flow synchronously, the stagnation of heat after conduction and exchange is avoided, and the heat is easily conducted and diffused to the outside through several capillaries 11 located in the external environment, achieving the effect of heat dissipation and cooling. Moreover, the cooled heat-absorbing liquid exchanges heat with the hot air again.

[0038] Furthermore, the middle part of the transmission rod 10 is rotatably connected to the middle part of the heat-absorbing liquid loading frame 7 via a sealed bearing, and the upper end of the middle part of the transmission rod 10 is rotatably connected to the middle part of the square grid cover 8 via a sealed bearing.

[0039] Furthermore, a three-leaf frame 13 is installed in the middle of the short tube 4, and the motor 14 is fixedly connected to the hole structure in the middle of the three-leaf frame 13. A circular mesh 2 is installed at the outer end of the short tube 4.

[0040] Please see Figure 6 and 7 As shown, the outer end port of the air outlet duct 81 is located on the side wall of the square grille cover 8, and the top edge of the square grille cover 8 is connected to the bottom edge of the mesh partition 3. The mesh partition 3 is located inside the housing of the pulse power exchanger 1, and is located at the bottom of the housing and connected to the edge of the bottom frame 6 located in the external environment. The bottom of the housing is lower than the height of the bottom frame 6.

[0041] In use, the heat exchange and heat dissipation structure is first installed at the corresponding position inside the pulse power exchanger 1 via the grid partition 3, with the bottom frame 6 exposed to the external environment. The motor 14 drives the suction fan blade 12 at one end and the micro water pump 9 connected to the other end via the transmission rod 10. The purpose is to: 1. draw hot air from inside the pulse power exchanger 1 into the air outlet duct inside the square grid cover 8 and discharge it from the external port of the air outlet duct through several heat absorption promoting components; 2. circulate the heat absorption liquid in the heat absorption liquid container 7 through the water outlet pipe 91, water inlet pipe 92, several wooden conical shells 5, and several connected capillary tubes 11. In summary, by synchronously flowing hot air and heat-absorbing liquid, the stagnation of heat after conduction and exchange is avoided. It is convenient to conduct and diffuse to the outside through several capillaries 11 located in the external environment, achieving the effect of heat dissipation and cooling. Moreover, the cooled heat-absorbing liquid exchanges heat with hot air again. The hot air enters the semi-permeable membrane 83 immersed in the heat-absorbing liquid, which can not only prevent the heat-absorbing liquid from seeping out, but also efficiently conduct the heat of the hot air to the heat-absorbing liquid. In addition, the fan blades 12 and the connecting parts are not placed at the heat dissipation holes on the outside of the equipment, but are placed inside the equipment, which ensures the airtightness of the equipment from external interference, and the air inside the equipment can circulate.
