Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a high-power current-sharing DC / DC self-detection power supply, which solves the problem that the existing DC / DC module power supply has insufficient dustproof ability, and cannot prevent dust from entering and adhering to the casing and the cooling fan. Internal problems improve the intelligence of the device, and can be cleaned in time when there is a lot of dust on the surface of the device, so as to avoid continuous cleaning of the dust on the surface of the device and increase the loss of work. alarm

Embodiment 1

[0032] see Figure 1-3 , the present invention provides a technical solution: a high-power current-sharing DC / DC self-detection power supply, including a power supply body 1 and a casing 2, a cooling fan 3 is arranged inside the casing 2, and the cooling fan 3 is electrically connected to the power supply body 1 ,

[0033] The internal setup of shell 2 has:

[0034] The heat dissipation device 4 has a cooling port 41, one side of the inner wall of the cooling port 41 is provided with a storage groove 42, the inside of the storage groove 42 is provided with a sliding block 43, and one side of the sliding block 43 is provided with a soft plastic film 44 , the soft plastic film 44 extends to the top of the cooling vent 41;

[0035] Dust collecting device 5, dust collecting device 5 has dust collecting groove 51, and dust collecting groove 51 runs through soft plastic film 44 and sliding block 43, and the top of soft plastic film 44 is provided with dust falling groove 52, and d...

Embodiment 2

[0039] see Figure 1-6 , the present invention provides a technical solution: on the basis of Embodiment 1, a buffer groove 7 is provided at the end of the soft plastic film 44 away from the sliding block 43, the buffer groove 7 runs through the soft plastic film 44, and the inner wall of the buffer groove 7 is Side rotation is connected with a buffer arc plate 8, the top of the buffer arc plate 8 is provided with a buffer spring 9, the buffer spring 9 is made of metal, and the top of the buffer spring 9 is connected to the conductive sheet 63.

[0040] Both sides of the inner wall of the dust falling tank 52 are provided with opening and closing plates 53 , and the inner bottom of the dust collecting tank 51 is connected with the opening and closing plates 53 through elastic plates 54 .

[0041] The inside of the receiving groove 42 is provided with a magnet block 14, the side of the sliding block 43 away from the soft plastic film 44 is provided with a metal sheet 15, and th...

Embodiment 3

[0046] see Figure 1-6 , the present invention provides a technical solution: on the basis of Embodiment 1, an alarm groove 10 is provided on the side of the soft plastic film 44 away from the conductive sheet 63, and the inner wall of the alarm groove 10 is provided with a metal sheet 11, an alarm 12 and The auxiliary power supply 13 and the soft plastic film 44 are made of hot-melt grade EVA plastic.

[0047] When in use, the heat generated during the working process of the power supply body 1 causes the temperature inside the shell 2 to rise. When the temperature inside the shell 2 reaches the melting point of the soft plastic film 44, the soft plastic film 44 begins to melt and shrink in volume, and the metal sheet 11, alarm The final connection between the device 12 and the auxiliary power supply 13 is gradually energized, and the alarm 12 starts to alarm. The volume shrinkage of the plastic is used to realize the connection of the alarm circuit, so that the device has a ...

Abstract

The invention discloses a high-power current-sharing DC / DC self-detection power supply which comprises a power supply main body and a shell. A heat dissipation fan is arranged in the shell, the heat dissipation fan is electrically connected with the power supply main body, a heat dissipation device is arranged in the shell, the heat dissipation device is provided with a heat dissipation opening, and a storage groove is formed in one side of the inner wall of the heat dissipation opening; a dust collecting device is included and is provided with a dust collecting groove, and the dust collecting groove penetrates through the soft plastic film and the sliding block; and an air extractor is included, and the invention relates to the technical field of DC / DC power supplies. According to the high-power current-sharing DC / DC self-detection power supply, the purpose of improving the dust removal capacity is achieved, dust can be prevented from entering and adhering to the shell and the interior of the heat dissipation fan, the intelligent degree of the device is improved, dust can be timely cleaned when the dust on the surface of the device is too much, and a condition that the dust on the surface of the device is continuously cleaned to increase work loss is avoided; and the power supply has an alarm capability, and can technically give an alarm when the internal temperature is too high.

Description

technical field [0001] The invention relates to the technical field of DC / DC power supplies, in particular to a high-power current-sharing DC / DC self-detection power supply. Background technique [0002] As a DC / DC module power supply, it is widely used in communication fields such as switching equipment, access equipment, mobile communication, microwave communication, optical transmission, routers, etc., as well as automotive electronics, aerospace and other fields. In the communication field, communication systems are generally based on -48V or +24V power supply, there will be one or more DC / DC module power supplies in the system to convert the voltage of the DC power supply into the working voltage required by the circuit board. [0003] However, the existing DC / DC module power supply has insufficient dust-proof ability, and it is impossible to prevent dust from entering and adhering to the inside of the casing and cooling fan. Dust increases the loss of work, does not h...
