Description

Technical Field

[0001] The utility model relates to the technical field of switching power supplies, in particular to a switching power supply with a heat dissipation structure for fire fighting. Background Art

[0002] In fire protection systems, various devices such as fire alarm controllers, detectors, and fire linkage modules require a continuous and stable power supply. DIN-rail switching power supplies can provide precise and stable voltage and current to ensure that these devices can operate normally at all times. Even when the power grid fluctuates or other abnormal conditions occur, the output stability can be maintained to avoid false alarms, missed alarms, or failure to start up fire protection equipment due to power supply problems.

[0003] Although current switching power supplies usually have heat dissipation holes, when used in dusty environments, external dust will pass through these heat dissipation holes into the casing and adhere to the switching power supply components, seriously affecting the heat dissipation capacity of the switching power supply. If a filter is added inside, after long-term use, the filter will be clogged with dust, resulting in a decrease in ventilation efficiency and affecting its heat dissipation capacity. Utility Model Content

[0004] The main purpose of the utility model is to provide a switching power supply with a heat dissipation structure for fire fighting, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a switching power supply with a heat dissipation structure for fire fighting, comprising a switching power supply main body, a shell is provided on the upper part of the switching power supply main body, an air inlet is provided in the middle part of the upper side of the shell, air outlets are provided on the front and rear sides of the upper part of the switching power supply main body, a card slot is installed on the upper part of the switching power supply main body, and a filter assembly is slidably connected inside the card slot.

[0006] Preferably, fins are fixedly connected to the left and right sides of the switching power supply body.

[0007] Preferably, a fan is installed on the top wall of the switching power supply body, and the fan is aligned with the air inlet.

[0008] Preferably, the filter assembly includes a filter screen, a frame and a rubber ring. The periphery of the filter screen is fixedly connected to the inside of the frame. The periphery of the frame is fixedly connected to the inside of the rubber ring. The periphery of the rubber ring is arranged inside the card slot.

[0009] Preferably, the front portion of the switching power supply body is rotatably connected to a baffle via a torsion spring, and a stopper is provided at the front portion of the switching power supply body, and the stopper is provided on one side of the baffle.

[0010] Preferably, a temperature sensor and a controller are installed inside the rear side of the switching power supply body, and the controller is electrically connected to the temperature sensor and the fan.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The temperature of the switching power supply body is detected by the temperature sensor. When the temperature of the switching power supply body is too high, the controller drives the fan to run, thereby driving the outside air through the air inlet into the shell, thereby dissipating the heat of the switching power supply body, and the hot air inside the shell is discharged to the outside through the air outlet, thereby greatly improving the heat dissipation effect of the switching power supply body. The baffle is kept vertically in a normal state, so that the baffle blocks the front of the filter assembly to prevent the filter assembly from falling from the slot. When the filter assembly needs to be replaced or cleaned, the baffle is pushed to one side with a finger to pull the filter assembly out of the slot. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-4As shown, a switching power supply with a heat dissipation structure for fire protection includes a switching power supply main body 1, a shell 2 is provided on the upper part of the switching power supply main body 1, an air inlet 6 is opened in the middle of the upper side of the shell 2, and air outlets 8 are opened on the front and rear sides of the upper part of the switching power supply main body 1. A card slot 3 is installed on the upper part of the switching power supply main body 1, and a filter assembly 4 is slidably connected inside the card slot 3. The air flow between the inside of the shell 2 and the outside is increased through the air inlet 6 and the air outlet 8, thereby improving the heat dissipation capacity of the switching power supply main body 1, and the filter assembly 4 can filter the air to prevent dust from adhering to the switching power supply main body 1, and the card slot 3 makes it easy to withdraw the filter assembly 4, so that the filter assembly 4 can be replaced and cleaned.

[0020] Fins 5 are fixedly connected to the left and right sides of the switching power supply body 1 , and the fins 5 increase the heat dissipation capacity of the switching power supply body 1 , thereby improving the heat dissipation capacity of the switching power supply body 1 .

[0021] A fan 7 is installed on the top wall of the switching power supply body 1. The fan 7 is aligned with the air inlet 6. The fan 7 drives the outside air into the housing 2 through the air inlet 6, thereby dissipating the heat of the switching power supply body 1. The hot air inside the housing 2 is discharged to the outside through the air outlet 8, thereby greatly improving the heat dissipation effect of the switching power supply body 1.

[0022] The filter assembly 4 includes a filter screen 401, a frame 402 and a rubber ring 403. The outer periphery of the filter screen 401 is fixedly connected to the inside of the frame 402, the outer periphery of the frame 402 is fixedly connected to the inside of the rubber ring 403, and the outer periphery of the rubber ring 403 is arranged inside the card slot 3. The filter screen 401 is supported and fixed by the frame 402, and the sealing performance between the frame 402 and the card slot 3 is increased by the rubber ring 403, thereby preventing dust from entering the interior of the shell 2 through the gap between the card slot 3 and the frame 402.

[0023] The front of the switching power supply body 1 is rotatably connected to a baffle 12 through a torsion spring. A stopper 11 is provided at the front of the switching power supply body 1. The stopper 11 is provided on one side of the baffle 12. The baffle 12 is kept in a vertical state under normal conditions, so that the baffle 12 blocks the front of the filter assembly 4 to prevent the filter assembly 4 from falling from the inside of the card slot 3. When the filter assembly 4 needs to be replaced or cleaned, the baffle 12 can be pushed to one side with a finger to pull the filter assembly 4 out of the card slot 3.

[0024] A temperature sensor 9 and a controller 10 are installed inside the rear side of the switching power supply body 1. The controller 10 is electrically connected to the temperature sensor 9 and the fan 7. The temperature of the switching power supply body 1 is detected by the temperature sensor 9. When the temperature of the switching power supply body 1 is too high, the fan 7 is driven to operate by the controller 10, so that the outside air is driven by the fan 7 to enter the inside of the housing 2 through the air inlet 6, thereby dissipating the heat of the switching power supply body 1, and the hot air inside the housing 2 is discharged to the outside through the air outlet 8, thereby greatly improving the heat dissipation effect of the switching power supply body 1.

[0025] Working principle:

[0026] The temperature of the switching power supply body 1 is detected by the temperature sensor 9. When the temperature of the switching power supply body 1 is too high, the fan 7 is driven to operate by the controller 10, thereby driving the outside air through the air inlet 6 to enter the interior of the housing 2 through the fan 7, thereby dissipating the heat of the switching power supply body 1, and the hot air inside the housing 2 is discharged to the outside through the air outlet 8, thereby greatly improving the heat dissipation effect of the switching power supply body 1. The baffle 12 is kept in a vertical state under normal conditions, so that the baffle 12 blocks the front of the filter assembly 4 to prevent the filter assembly 4 from falling from the inside of the card slot 3. When the filter assembly 4 needs to be replaced or cleaned, the baffle 12 is pushed to one side with a finger to pull the filter assembly 4 out of the card slot 3.
