DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0024] Example 1

[0025] like Figure 1 , Figure 2 and Figure 3 As shown;

[0026] A cooling structure for an outdoor power supply comprises a shell 1 and a movable door 2. A heat-conducting frame 3 is arranged inside the shell 1, a power supply is arranged inside the heat-conducting frame 3, and a plurality of heat sinks 4 are arranged outside the heat-conducting frame 3. A cooling pipe 5 is inserted through the middle of the heat sink 4, and both ends of the cooling pipe 5 are connected to a micro pump 6. The movable door 2 is hinged to the end of the shell 1. A plurality of first heat dissipation holes 7 are opened on the shell 1. A sealing plate 8 is arranged on the inner side of the shell 1. The sealing plate 8 is provided with flexible parts 9 and second heat dissipation holes 10 corresponding to the first heat dissipation holes 7 one by one.

[0027] It should be noted that: in this embodiment, the heat-conducting frame 3 and the heat sink 4 are integrally formed, and the heat-conducting frame 3 and the heat sink 4 are preferably made of metal, and the power supply is in close contact with the inner wall of the heat-conducting frame 3 .

[0028] In the present embodiment: by arranging a heat-conducting frame 3 and a heat sink 4 on the outside of the power supply, and spirally winding the cooling tube 5 inside the heat sink 4, the heat conduction efficiency between the heat sink 4 and the power supply is high, thereby improving the heat dissipation efficiency of the cooling tube 5; at the same time, in the non-working state, the sealing plate 8 can drive the flexible part 9 to close the first heat dissipation hole 7, thereby effectively preventing the entry of dust.

[0029] In an optional embodiment, the bottom and the top of the heat-conducting frame 3 are connected to the housing 1 through a support member 11 , and a plurality of cooling fans 12 are disposed inside the bottom support member 11 .

[0030] In this embodiment, the wind direction of the heat dissipation fan 12 is upward, so that the heat dissipation fins 4 and the cooling tubes 5 can be blown to dissipate heat.

[0031] like Figure 4 and Figure 5 As shown;

[0032] In an optional embodiment, a plurality of heat sinks 4 are horizontally arranged on the heat conducting frame 3 at equal intervals.

[0033] In this embodiment: when the actual outdoor power supply is placed, the heat sink 4 is parallel to the ground to prevent it from being squeezed and deformed, and to ensure the stability of the installation with the cooling tube 5. A through hole is opened on the heat sink 4, and the cooling tube 5 fits tightly with the through hole.

[0034] In an optional embodiment, the cooling tube 5 is serpentinely inserted in the middle of the heat sink 4 and filled with coolant. The cooling tube 5 is respectively connected to the input end and the output end of the micro pump 6, so that the micro pump 6 can be used to circulate the coolant in the cooling tube 5.

[0035] In an optional embodiment, a compression spring 13 is connected between one end of the sealing plate 8 and the inner wall of the shell 1 , and a limiting plate 14 fixed to the inner wall of the shell 1 is provided on one side of the sealing plate 8 close to the heat conducting frame 3 .

[0036] In this embodiment, when the movable door 2 is opened, the compression spring 13 pushes the sealing plate 8 out and ensures that the first heat dissipation hole 7 is aligned with the second heat dissipation hole 10 . The limiting plate 14 can guide the expansion and contraction of the sealing plate 8 .

[0037] like Figure 6 As shown;

[0038] In an optional embodiment, the flexible member 9 is a hemispherical structure, and the flexible member 9 and the second heat dissipation holes 10 are alternately arranged in the horizontal direction.

[0039] In this embodiment: the flexible member 9 and the second heat dissipation holes 10 are evenly spaced in the vertical direction. When the flexible member 9 is aligned one by one with the first heat dissipation holes 7, the second heat dissipation holes 10 are located between the two first heat dissipation holes 7 in the horizontal direction. When the second heat dissipation holes 10 are aligned one by one with the first heat dissipation holes 7, the flexible member 9 is located between the two first heat dissipation holes 7 in the horizontal direction.

[0040] In an optional embodiment, the radius of the flexible member 9 is greater than the radius of the first heat dissipation hole 7 , and the radius of the first heat dissipation hole 7 is equal to the radius of the second heat dissipation hole 10 .

[0041] In this embodiment: in actual use, the flexible member 9 is always in an extruded state. When the flexible member 9 is aligned with the first heat dissipation holes 7 one by one, the flexible member 9 extends into the first heat dissipation holes 7 and completely seals them, thereby achieving a waterproof and dustproof effect.

[0042] The working principle and use process of the utility model are as follows: when the power supply is needed, the movable door 2 is opened, at which time the compression spring 13 pushes the sealing plate 8 out and ensures that the first heat dissipation hole 7 is aligned with the second heat dissipation hole 10. When the temperature sensor detects that the temperature reaches the set value, the micro pump 6 and the cooling fan 12 are started, and the micro pump 6 drives the coolant in the cooling pipe 5 to circulate, and the cooling fan 12 can dissipate heat for the cooling pipe 5 at the output end of the micro pump 6 (actually, a semiconductor heat sink can be provided at the cooling pipe 5 at the output end of the micro pump 6 for active heat dissipation); when the power supply is no longer used, the movable door 2 is closed, the movable door 2 squeezes the sealing plate 8 to reset, and at the same time the sealing plate 8 drives the flexible member 9 thereon to align with the first heat dissipation hole 7 one by one, thereby closing the first heat dissipation hole 7.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
