[0026] A shell 1, a square frame 2 is arranged near the inner wall of the shell 1, the square frame 2 divides the center of the shell 1 and the side wall of the shell 1 into two spaces, and a partition plate 3 is also arranged between the square frame 2 and the inner wall of the shell 1 to form a one-way flow channel 4 between the inner wall of the shell 1 and the square frame 2;

[0027] The first flow pipe 5 and the second flow pipe 6 are respectively provided on the block 2 , and the first flow pipe 5 and the second flow pipe 6 are respectively provided with a first one-way valve and a second one-way valve having different flow directions;

[0028] The air inlet 7 and the air outlet 8 are respectively provided on the outer side walls of the housing 1 on both sides of the partition plate 3 . If Figure 1-5As shown, a power converter comprises a housing 1, an air inlet 7 and an air outlet 8 arranged on the outer wall of the housing 1, wherein the housing 1 plays a protective role for the entire device, a square frame 2 is installed near the inner wall of the housing 1, and the square frame 2 divides the center of the housing 1 and the side wall of the housing 1 into two spaces, wherein various electronic components of the power converter are installed in the space located in the square frame 2, providing a position for the installation of various electronic components, and a partition is installed in the space between the square frame 2 and the inner wall of the housing 1, and the partition is connected to the top and bottom of the housing 1, and at the same time the partition is connected The inner wall of the shell 1 and the square frame 2 are connected to form a one-way flow channel 4 between the square frame 2 and the inner wall of the shell 1. When the air outside the shell 1 enters the flow channel 4, it can flow in its flow channel 4 in one direction; wherein, the first one-way valve and the second one-way valve are installed in the first flow pipe 5 and the second flow pipe 6 installed on the square frame 2, and the flow directions of the first one-way valve and the second one-way valve are different, wherein the first one-way valve and the second one-way valve can be Tesla one-way valves to realize the one-way flow of the fluid, and the air entering through the flow channel 4 enters the first one-way valve 5 and the second one-way valve 6. One of the one-way valve and the second one-way valve enters the frame 2, and then flows into the circulation channel 4 through the other one and continues to flow with the gas in the circulation channel 4. The gas entering the frame 2 exchanges heat inside the frame 2, and the gas after heat exchange is discharged from the shell 1; wherein, new air is transported into the shell 1 through the air inlet 7, and the air entering the circulation channel 4 flows along the circulation channel 4 to the air outlet 8, wherein the air enters the frame 2 for heat exchange, and then is transported out of the shell 1 from the air outlet 8, wherein, when the electronic components in the frame 2 are used, heat is generated, so that the space pressure in the frame 2 increases, and the heated air is transported into the circulation channel 4 through one of the first circulation pipe 5 or the second circulation pipe 6, and the first one-way valve and the second one-way valve with opposite flow directions are matched, and as the air flow flows to the outside of the shell 1, part of the air in the circulation channel 4 enters the frame 2, and new air is supplemented to it, forming a circulation in the frame 2, and the heat in the frame 2 is taken away during the gas flow, and it is effectively cooled, and the heat in the shell 1 is effectively output in time, thereby improving the use efficiency of the power converter.

[0029] In some embodiments, the first flow pipe 5 and the second flow pipe 6 are both disposed on the side wall of the frame 2 away from the air inlet 7, and the first flow pipe 5 and the second flow pipe 6 are connected to two spaces respectively. Figure 1-5 As shown, the first flow pipe 5 and the second flow pipe 6 are both installed on the side wall of the frame 2 away from the air inlet 7. This arrangement avoids the situation where the gas transportation in the frame 2 is too close to the air inlet 7, which will affect the entry of new air outside the shell 1 into the flow channel 4. This arrangement improves the efficiency of the air flow in the flow channel 4 and is beneficial for the air coming out of the frame 2 to be discharged to the air outlet 8.

[0030] In some embodiments, the flow direction in the circulation channel 4 is from the air inlet 7 to the air outlet 8. In the circulation channel 4, the first circulation tube 5 is closer to the air inlet 7 than the second circulation tube 6. The flow direction of the first circulation tube 5 is from the circulation channel 4 to the inside of the frame 2. Figure 1-5 As shown, the direction of air flowing in the circulation channel 4 is from the air inlet 7 to the air outlet 8. By setting the position of the first circulation tube 5 in the circulation channel 4 closer to the air inlet 7 than the second circulation tube 6, and the flow direction of the first circulation tube 5 flows from the circulation channel 4 to the frame 2, that is, the flow direction of the first one-way valve is from the circulation channel 4 to the frame 2, wherein the flow direction of the second one-way valve is opposite to that of the first one-way valve, so that the air first passes through the first circulation tube 5 into the frame 2 to cool the electronic components inside the frame 2, and then is transported to the circulation channel 4 through the second circulation tube 6, and as the air in the circulation channel 4 flows to the outside of the shell 1, the smooth circulation of the circulation channel 4 and the smooth circulation of the air in the frame 2 are guaranteed to improve the heat exchange efficiency.

[0031] In some embodiments, the side wall of the frame 2 is evenly provided with a plurality of pairs of heat dissipation bars 9, and the heat dissipation bars 9 are all penetrated from the inside of the frame 2 to the flow channel 4 outside the frame 2. Figure 1-5 As shown, a plurality of pairs of heat dissipation strips 9 are evenly arranged on the side wall of the frame 2. The heat dissipation strips 9 are made of a heat-conducting material, which may be thermal grease.

[0032] In some embodiments, the heat dissipation bars 9 are all in an arc shape, one end of each pair of the heat dissipation bars 9 is respectively close to the top and the bottom of the frame 2, and the other end of the heat dissipation bars 9 extends to the middle of the frame 2, and the extension direction of the other end of the heat dissipation bars 9 is the same as the flow direction of the flow channel 4. Figure 1-5 As shown, the shape of the heat dissipation strip 9 is set to be arc-shaped, one end of each pair of heat dissipation strips 9 is respectively close to the top and the bottom of the square frame 2, and the other end of the heat dissipation strip 9 extends to the middle of the square frame 2, and the extension direction of the other end of the heat dissipation strip 9 is the same as the flow direction of the circulation channel 4. The advantage of this arrangement is that when the air flows in the circulation channel 4, the heat of the heat dissipation strip 9 is taken away along the direction of the air flow, avoiding the heat dissipation strip 9 from restricting the airflow.

[0033] In some embodiments, a filter plate 10 is disposed outside the air inlet 7, and the filter plate 10 and the air inlet 7 are detachably connected. L-shaped slide grooves 11 are disposed near the top and bottom of the air inlet 7, and the top and bottom of the filter plate 10 are respectively engaged with the L-shaped slide grooves 11. Figure 1-5As shown, the filter plate 10 of the air inlet 7 is snap-connected by a pair of L-shaped grooves 11 between the top and bottom of the air inlet 7, wherein the specification of the filter plate 10 and the L-shaped groove 11 are adapted to the space at the air inlet 7. When in use, the filter plate 10 is snapped in between to filter the air entering the shell 1 to prevent dust and other suspended matter in the air from entering. After a certain period of use, the filter plate 10 can be disassembled and cleaned, wherein the filter holes are evenly arranged on the filter plate 10 and meet the dust removal requirements.

[0034] In some embodiments, a filter 12 is provided at one end of the air outlet 8 near the outer outer shell 1 , and a fan 13 is provided in the air outlet 8 . If Figure 1-5 As shown, a filter screen 12 is arranged outside the shell 1 near the air outlet 8. The filter screen 12 can be directly covered on the air outlet 8 or can be snap-connected, screwed, etc., and it acts to protect the internal fan 13. The fan 13 is commercially available and can exhaust the fan 13 to transport the gas in the circulation channel 4 to the outside of the shell 1, so that the air flow in the circulation channel 4 forms a unidirectional flow, forming an external circulation from the air inlet 7 to the air outlet 8, and promoting the internal circulation in the frame 2 to dissipate heat in the frame 2.
