Description

Technical Field

[0001] The utility model belongs to the technical field of inverters, and in particular relates to an inverter heat dissipation device. Background Art

[0002] Photovoltaic inverters are indispensable equipment in photovoltaic power supply. Photovoltaic inverters generally need to be installed with cooling fans. In actual installation scenarios, multiple photovoltaic inverters need to be installed side by side. At this time, the distance between photovoltaic inverters is generally small, which is not convenient for the installation of radiators. In addition, after some photovoltaic inverters are installed, there are obstacles on the left and right sides, such as protruding walls. At this time, there is little remaining space after installation against the wall. The photovoltaic inverter requires a large amount of disassembly work after installation. When repairing or cleaning exposed heat dissipation components, they need to be disassembled as a whole. However, due to spacing restrictions and small operating space, the exposed heat dissipation components cannot be directly pulled out as a whole, resulting in a large maintenance workload and difficulty in maintenance.

[0003] In order to solve the above problems, the present application proposes an inverter heat dissipation device. Utility Model Content

When a module in the heat dissipation component is damaged, the damaged module can be removed and replaced separately without replacing the entire component. When installing and disassembling the heat dissipation component in a narrow space, the operator pulls the handle to extend the first heat dissipation component.

DETAILED DESCRIPTION

[0020] 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.

[0021] Example 1

[0022] like Figures 1 to 5 As shown;

[0023] An inverter heat dissipation device comprises a box body 1 and an inverter body 2 installed in the box body 1, heat dissipation grilles 3 are provided on both sides of the top of the box body 1, a heat dissipation assembly 40 is provided inside the box body 1 above the inverter body 2, the heat dissipation assembly 40 comprises a first heat dissipation member 41, a second heat dissipation member 42 and a third heat dissipation member 43 arranged in sequence, ears 421 are fixed on both sides of the second heat dissipation member 42, the second heat dissipation member 42 is connected to the first heat dissipation member 41 and the third heat dissipation member 43 through the ears 421, an end of the third heat dissipation member 43 away from the second heat dissipation member 42 is fixed with an electric terminal A44, another group of electric terminals A44 are installed at positions corresponding to the electric terminals A44 in the box body 1, and the heat dissipation assembly 40 is inserted into the box body 1 from one side of the box body 1;

[0024] In this embodiment: when installing the utility model, the heat dissipation component 40 is inserted into the box body 1 from one side of the box body 1, and the heat dissipation component 40 is located above the inverter body 2. When the heat dissipation component 40 is working, the heat dissipated by the inverter body 2 is blown to the outside through the heat dissipation grille 3 to achieve heat dissipation of the inverter body 2. The heat dissipation component 40 is an assembly structure. When installing, the first heat dissipation member 41 and the third heat dissipation member 43 are installed on the ear pieces 421 on both sides of the second heat dissipation member 42, and then locked by screws. When a module in the heat dissipation component 40 is damaged, the damaged module can be removed and replaced separately without the need for overall replacement. When installing and disassembling the heat dissipation component 40 in a narrow space, the operator pulls the handle 5 to extend the first heat dissipation member 41. At this time, the first heat dissipation member 41 can be removed by loosening the screws. After taking out the first heat dissipation member 41, the second heat dissipation member 42 is pulled out. In this way, the heat dissipation component 40 does not need to be completely pulled out to be removed, which is convenient for operators to install and disassemble the utility model in a narrow space.

[0025] It should be noted that the ear piece 421 is a magnetic iron sheet. During installation, the first locking is to magnetically adsorb the first heat sink 41 and the third heat sink 43 on both sides of the second heat sink 42, and then the second locking is performed by screws. It can be understood that the parts of the first heat sink 41 and the third heat sink 43 that are in contact with the ear piece 421 are made of iron and the structure is adapted to the ear piece 421.

[0026] It should be noted that the heat dissipation component 40 is connected to the power supply circuit via the power terminal A44.

[0027] Going further:

[0028] In an optional embodiment, an indicator light 45 is mounted on the surface of the first heat sink 41 .

[0029] In this embodiment: through this design, maintenance personnel can observe the working condition of the fan in the heat dissipation component 40 through the indicator light 45, so as to quickly know which fan is damaged and facilitate maintenance work.

[0030] It should be noted that the indicator lights 45 and the fans in the heat dissipation assembly 40 are arranged in a one-to-one correspondence. Specifically:

[0031] In an optional embodiment, a viewing window 7 is installed on the top surface of the box body 1 .

[0032] In this embodiment: through this design, maintenance personnel can directly view the situation inside the box body 1 through the viewing window 7, which is convenient for maintenance work.

[0033] It should be noted that the viewing window 7 is made of explosion-proof glass.

[0034] Going further:

[0035] In an optional embodiment, a guide rail 6 is fixed to the inner wall of the box body 1 corresponding to the heat dissipation component 40 . The guide rail 6 is a C-shaped rod, and the guide rail 6 clamps the two side edges of the heat dissipation component 40 .

[0036] In this embodiment: through this design, the guide rail 6 allows maintenance personnel to pull out and insert the heat dissipation component 40 smoothly. At the same time, the guide rail 6 protects the heat dissipation component 40 to prevent the gravity of the heat dissipation component 40 from exerting pressure on the ear piece 421 to cause it to deform. The guide rail 6 also allows the power terminal A44 to accurately reach the correct position, thereby improving the reliability of the utility model.

[0037] Going further:

[0038] In an optional embodiment, a handle 5 is installed at one end of the first heat sink 41 extending outside the box body 1 .

[0039] In this embodiment: through this design, the handle 5 is convenient for maintenance personnel to install and disassemble the heat dissipation component 40.

[0040] Going further:

[0041] In an optional embodiment, an electrical terminal B422 is fixed on the surface of the ear piece 421 , and corresponding electrical terminals B422 are installed on the surfaces of the first heat sink 41 and the third heat sink 43 .

[0042] In this embodiment: Through this design, the power terminal B422 can enable the circuit of each heat sink in the heat sink assembly 40 to be installed inside it. When repairing and replacing a new heat sink, there is no need to reconnect the wires, which facilitates the rapid replacement of a new heat sink.

[0043] The working principle and use process of the utility model: when installing the utility model, the heat dissipation component 40 is inserted into the box body 1 from one side of the box body 1, and the heat dissipation component 40 is located above the inverter body 2. When the heat dissipation component 40 is working, the heat dissipated by the inverter body 2 is blown to the outside through the heat dissipation grille 3 to achieve heat dissipation of the inverter body 2. The heat dissipation component 40 is an assembly structure. When installing, the first heat dissipation member 41 and the third heat dissipation member 43 are installed on the ear pieces 421 on both sides of the second heat dissipation member 42, and then locked by screws. When a module in the heat dissipation component 40 is damaged, the damaged module can be removed and replaced separately without the need for overall replacement. When installing and disassembling the heat dissipation component 40 in a narrow space, the operator pulls the handle 5 to extend the first heat dissipation member 41. At this time, the first heat dissipation member 41 can be removed by loosening the screws. After taking out the first heat dissipation member 41, the second heat dissipation member 42 is pulled out. Disassembly is performed in this way, so that the heat dissipation component 40 does not need to be completely pulled out to be removed, which is convenient for operators to install and disassemble the utility model in a narrow space.

[0044] 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.
