Description

Technical Field

[0001] The utility model relates to the technical field of frequency converter protection, in particular to a frequency converter protection cover which is easy to install. Background Art

[0002] The inverter often outputs appropriate current and voltage according to the needs to meet the working requirements; however, when the inverter works for a long time, it will generate heat, which will cause the electronic components to burn out. Now we provide an inverter protection cover that is easy to install to solve the problem of low heat dissipation efficiency of the inverter when it works for a long time. Summary of the invention

[0003] The utility model realizes the purpose of internal heat dissipation by installing a fan on the bottom fan plate.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A frequency converter protective cover that is easy to install, comprising a fan plate, a fan, an L-guide rail profile, a guide rail, a cover body and a filter; the fan plate is fixedly connected to a mounting plate; the L-guide rail profile is fixedly connected to the mounting plate; the fan is mounted on the fan plate; one end of the L-guide rail profile is fixedly connected to the fan plate; the guide rail is fixedly connected to the cover body; the filter is mounted on the top of the cover body.

[0006] Preferably, the fan plate is provided with a groove, which cooperates with the cover body to limit the position of the cover body.

[0007] Preferably, the guide rails are located on both sides of the cover body; and the cover body is limited by cooperating with the L guide rail profile.

[0008] Preferably, the L guide rail profile is arranged symmetrically about the cover body.

[0009] Compared with the prior art, the gain effect of the utility model is:

[0010] 1. The cover body plays a protective role and is easy to disassemble and assemble.

[0011] 2. Can accelerate the dissipation of internal heat. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Example

[0019] See also Figure 1-4 A frequency converter protective cover which is easy to install comprises a fan plate 2, a fan 3, an L guide rail profile 4, a guide rail 5, a cover body 6 and a filter screen 7; the fan plate 2 is fixedly connected to the mounting plate 1; the L guide rail profile 4 is fixedly connected to the mounting plate 1; the fan 3 is mounted on the fan plate 2; one end of the L guide rail profile 4 is fixedly connected to the fan plate 2; the guide rail 5 is fixedly connected to the cover body 6; a filter screen 7 is installed on the top of the cover body 6.

[0020] The fan plate 2 is provided with a groove, which cooperates with the cover body 6 to limit the cover body 6.

[0021] The guide rails 5 are located on both sides of the cover body 6 , and cooperate with the L-guide rail profile 4 to limit the cover body 6 .

[0022] The L guide rail profile 4 is arranged symmetrically with respect to the cover body 6 .

[0023] Working principle: Install the inverter as a whole 8 on the mounting plate 1, slide the guide rail 5 on the cover 6 along the L guide rail profile 4 until the cover 6 reaches the groove on the fan plate 2; during the operation of the inverter, turn on the fan 3 to achieve rapid internal heat dissipation; if the inverter as a whole 8 is damaged, the cover 6 can be quickly pulled up for replacement.
