DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present utility model are given for purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations will be obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

[0017] Embodiment: Please refer to Figure 1 - Figure 4 The present utility model provides a technical solution: a radiator for a photovoltaic inverter that can accelerate air convection, including: a heat dissipation connection housing 1; a protective frame 2, the outer wall of the protective frame 2 is fixedly connected to the outer wall of the heat dissipation connection housing 1; a connection device 4, the outer wall of the connection device 4 is fixedly connected to the outer wall of the heat dissipation connection housing 1; a heat dissipation device 3, the outer wall of the heat dissipation device 3 is fixedly connected to the outer wall of the connection device 4; the heat dissipation connection housing 1 includes a connection box 11, the inner wall of the top of the connection box 11 is fixedly connected with an outlet heat sink 12, the inner wall of the bottom of the connection box 11 is fixedly connected with a fixing block 13, a ventilation groove 14 is opened in the wall of the fixing block 13, a dust filter net 15 is fixedly connected to the outer wall of the bottom of the fixing block 13, a fan 16 is fixedly connected to the outer wall of the connection box 11, the outer wall of the connection box 11 is fixedly connected to the outer wall of the protective frame 2, and the outer wall of the fixing block 13 is fixedly connected to the outer wall of the protective frame 2. The fan 16 fixed on the connection box 11 is operated, so that external gas quickly rushes into the inside of the connection box 11. During this process, since the fan 16 is inclined, the air flow direction is inclined upward, and the air flow outlet of the fan 16 is parallel to the aluminum sheet 31. The external air flow entering the inside of the connection box 11 is blown by the fan 16 and guided by the aluminum sheet 31. The air flow carries heat and moves to the middle of the connection box 11. Due to the upward inclined blowing of the air flow and the symmetric arrangement of the fans 16 on both sides of the connection box 11, the air flows on both sides continue to move upward after collision, thereby accelerating the air flow above the ventilation groove 14. According to Bernoulli's principle, the air below the fixing block 13 enters the ventilation groove 14 through the dust filter net 15, and the flowing gas moves out from above the ventilation groove 14. Also, because the temperature of the hot air is higher, the molecular movement speed is faster, and the distance between molecules increases, resulting in the density of the hot air being smaller than that of the cold air. According to the buoyancy principle, an object with a smaller density will float in a medium with a larger density. When there is a temperature difference, it will cause air convection. The hotter air rises due to its smaller density, and the relatively colder air around it will flow in to supplement, forming a convection cycle.

[0018] The connecting device 4 includes a copper plate 41. The outer wall of the copper plate 41 is fixedly connected with a connecting copper tube 42. The inner side wall of the connecting copper tube 42 is fixedly connected with an inner copper tube 43. A steam hole 44 is opened in the top wall of the inner copper tube 43, and a liquid hole 45 is opened in the bottom wall of the inner copper tube 43. One end of the copper plate 41 away from the connecting copper tube 42 is fixedly connected with the inner side wall of the connecting box 11, and the top of the connecting copper tube 42 is fixedly connected with the top end inside the connecting box 11. A coolant is contained in the connecting copper tube 42. Due to the connection method of the copper plate 41 and the connecting copper tube 42, heat moves upward from the bottom of the connecting copper tube 42. While the heat is moving, the high temperature will evaporate the coolant. The coolant in a vapor state floats upward due to vaporization and gradually transfers heat to the aluminum sheet 31 during the upward floating process. The inner copper tube 43 in the connecting copper tube 42 enters the inner copper tube 43 through the steam hole 44 at the top, and liquefies into a coolant when moving in the inner copper tube 43, and re-enters the space between the connecting copper tube 42 and the inner copper tube 43 through the liquid hole 45 at the bottom, thereby realizing the phase change heat transfer of the coolant.

[0019] The heat dissipation device 3 includes an aluminum sheet 31. A connecting hole 32 is opened in the wall of the aluminum sheet 31. The outer wall of the aluminum sheet 31 is fixedly connected with a heat-conducting copper tube 33. The outer wall of the heat-conducting copper tube 33 and the outer wall of the aluminum sheet 31 are both fixedly connected with the outer wall of the copper plate 41. The outer wall of the connecting copper tube 42 is fixedly connected with the inner wall of the aluminum sheet 31 through the connecting hole 32. The connecting hole 32 on the aluminum sheet 31 is tightly connected with the connecting copper tube 42 to ensure rapid heat transfer. When the fan 16 blows, an air flow flows into the heat-conducting copper tube 33. The air flow flows in the heat-conducting copper tube 33 and moves to the middle of the connecting box 11.

[0020] Working principle:

[0021] During use, the heat generated by the operation of the photovoltaic inverter is first transferred to the connection box 11 of the heat dissipation connection housing 1. Inside the connection box 11, the copper plate 41 and the connecting copper pipe 42 in the connecting device 4 receive the heat from the heat dissipation connection housing 1. The aluminum sheet 31 of the heat dissipation device 3 further receives and dissipates the heat through the connection hole 32 and the heat conduction copper pipe 33, so that the heat is fully released in the internal spaces of the protection frame 2 and the connection box 11. At the same time, the fixed fan 16 on the connection box 11 operates, causing the external gas to quickly rush into the inside of the connection box 11. During this process, since the fan 16 is inclined, the air flow direction is inclined upward, and the air flow outlet of the fan 16 is parallel to the aluminum sheet 31. The outside air flow entering the inside of the connection box 11 is blown by the fan 16 and guided by the aluminum sheet 31, and the air flow carries the heat and moves to the middle of the connection box 11. Due to the inclined upward blowing of the air flow and the symmetrical arrangement of the fans 16 on both sides of the connection box 11, the air flows on both sides continue to move upward after collision, thereby accelerating the air flow above the ventilation slot 14. According to Bernoulli's principle, the air below the fixed block 13 enters the ventilation slot 14 through the dust filter net 15, and the flowing gas moves out from above the ventilation slot 14. Also, because the temperature of the hot air is higher, the molecular movement speed is faster, and the distance between molecules increases, resulting in the density of the hot air being smaller than that of the cold air. According to the buoyancy principle, an object with a smaller density will float in a medium with a larger density. When there is a temperature difference, it will cause air convection. The relatively hot air rises due to its smaller density, and the relatively cold air around it will flow over to replenish, forming a convection cycle. Therefore, the hot air in the middle of the connection box 11 at this time will move upward and be blown out of the connection box 11 through the outlet heat dissipation fin 12. Through the blowing of the fan 16, the increase in air flow by Bernoulli's principle, and the convection effect, the flow rate of the high-temperature air flow blown out of the connection box 11 is increased. By accelerating the air convection, the inside of the connection box 11 is quickly blown out, accelerating the air convection around the radiator, thereby enhancing the heat dissipation effect. And the flowing air flow also accelerates the heat dissipation effect of the outlet heat dissipation fin 12. Through the coordinated work of each component, the heat generated by the photovoltaic inverter is effectively dissipated quickly, ensuring the stable operation of the photovoltaic inverter within the normal working temperature range.

[0022] The setting of the heat dissipation device 3 and the connection device 4 further enhances the heat dissipation effect. A coolant is contained in the connecting copper tube 42. Due to the connection method of the copper plate 41 and the connecting copper tube 42, heat moves upward from the bottom of the connecting copper tube 42. While the heat is moving, the high temperature will evaporate the coolant. The vaporized coolant floats upward due to vaporization and gradually transfers the heat to the aluminum fin 31 during the upward floating process. The inner copper tube 43 in the connecting copper tube 42 enters the inner copper tube 43 through the steam hole 44 at the top, liquefies into a coolant when moving in the inner copper tube 43, and re-enters the space between the connecting copper tube 42 and the inner copper tube 43 through the liquid hole 45 at the bottom, thereby realizing the phase change heat transfer of the coolant and transferring heat more efficiently. The connection hole 32 on the aluminum fin 31 is tightly connected to the connecting copper tube 42 to ensure rapid heat transfer. When the fan 16 blows, air flows into the heat conduction copper tube 33. The air flows in the heat conduction copper tube 33 and moves to the middle of the connection box 11, further improving the cooling efficiency of the radiator.
