Description

Technical Field

[0001] The utility model relates to the technical field of regulated power supplies, and particularly relates to an outdoor overheat-proof regulated power supply. Background Art

[0002] A regulated power supply is an electronic device that can provide a stable alternating current or direct current for a load, including two categories: an AC regulated power supply and a DC regulated power supply. When there is an instantaneous fluctuation in the grid voltage or load, the regulated power supply will compensate for the voltage amplitude at a response speed of 10 - 30 ms, making it stable within ±2%. Most of the existing outdoor regulated power supplies often lack an overheat protection device. When encountering high-temperature weather outdoors, air circulation is carried out through its own heat dissipation holes, and it is impossible to quickly dissipate heat inside, resulting in poor heat dissipation effect due to excessive temperature, overheating of internal modules, and thus easy damage to the regulated power supply.

Specific embodiments

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] The present utility model will be further described below with reference to the embodiments.

[0026] Embodiment: An outdoor anti-overheating regulated power supply includes a regulated power supply box 1 and a module 2 fixedly installed inside it. By means of the prior art, a temperature sensor and a control panel can be arranged inside the regulated power supply box 1, so that when the internal temperature of the regulated power supply box 1 reaches overheat, the temperature sensor and the control panel cooperate to control the internal components to cool down. A plurality of exhaust ports 4 are opened on the other side of the regulated power supply box 1. It also includes an anti-overheating component for cooling the regulated power supply in the regulated power supply box 1. By setting the anti-overheating component, heat dissipation treatment can be carried out on the overheated inside of the regulated power supply box 1, thereby preventing damage to the regulated power supply due to too high temperature. The anti-overheating component includes a mobile rack 5 arranged in the regulated power supply box 1, and the mobile rack 5 is fixedly connected to the regulated power supply box 1 through four electric push rods 6. A plurality of air outlets 7 are opened at one end of the mobile rack 5, and an exhaust fan 8 is fixedly installed at the other end of the mobile rack 5. It also includes a cooling mechanism for the module 2 arranged on the mobile rack 5.

[0027] Refer to the appendix Figures 1 - 5As shown in the figure, the module 2 that works for a long time is further cooled by a cooling mechanism. The cooling mechanism includes hollow heat sinks 9 respectively arranged on both sides of the module 2 and a water tank assembly arranged in the mobile frame 5 for quickly dissipating heat from the heat sink 9. The heat sink 9 is made of copper with good thermal conductivity. The heat sink 9 that absorbs heat can be quickly cooled by the water tank assembly, so that the heat sink 9 can better absorb the heat of the module 2, thereby achieving the purpose of heat dissipation and cooling of the voltage-stabilized power supply. Specifically, a plurality of air outlets 7 are provided with notches below, and a second filter 10 is provided in the notches. The second filter 10 corresponds to the exhaust port 4 one by one and is closely attached. Under normal temperature conditions, the voltage-stabilized power supply dissipates internal heat through the two ends of the voltage-stabilized power supply through its own air circulation, that is, through the second filter 10 and the air outlet 7 or through the first filter 3 for heat dissipation. At the same time, the second filter 10 and the first filter 3 both have the effect of preventing external dust and impurities from entering the interior of the voltage-stabilized power supply.

[0028] See attached Figures 1 - 5 As shown in, specifically, when the temperature sensor in the voltage-stabilized power supply senses that the temperature is too high, the control panel starts the exhaust fan 8 to discharge a large amount of heat in the voltage-stabilized power supply box 1 and the heat absorbed by the heat sink 9 from the module 2. The heat sink 9 is respectively close to both sides of the module 2, and a plurality of through holes 11 are opened on the heat sink 9. The opening of the plurality of through holes 11 makes the air flow outward better, and at the same time makes the electric push rod 6 contract to drive the mobile frame 5 to move downward. The water tank assembly includes an upper water tank 12 fixedly connected to the mobile frame 5, a water pump 13 is fixedly installed on one side of the upper water tank 12, and a lower water tank 14 is fixedly installed on one side of the module 2. The upper water tank 12, the water pump 13, the lower water tank 14 and the heat sink 9 are connected in turn by ordinary water pipes, and the heat sink 9 is connected to the upper water tank 12 by a water pipe group, and the water pipe group includes a fixed connection The upper water pipe 15 in the upper water tank 12 is fixedly connected to the top heat sink 9 with a lower water pipe 16, and the upper water pipe 15 is slidably connected to the lower water pipe 16. The lower water pipe 16 is provided with a wide row of holes 17. Two discharge ports 18 are provided on the upper water pipe 15, and the upper water pipe 15 is slidably connected to the top of the wide row of holes 17. The movable frame 5 moves downward to drive the upper water pipe 15 to move downward and move to the wide row of holes 17 of the lower water pipe 16, so that the coolant in the upper water tank 12 flows from the discharge port 18 of the upper water pipe 15 into the lower water pipe 16, and then flows through the heat sink 9 to the lower water tank 14 at the bottom. At the same time, the control panel starts the water pump 13 to pump the coolant in the lower water tank 14 back to the upper water tank 12. In this process, the coolant takes away the heat in the heat sink 9, so that the heat sink 9 cools down faster, and the efficiency of absorbing the heat in the module 2 is higher.

[0029] See attached Figures 1 - 5As shown, specifically, when the moving frame 5 moves downward, the second filter screen 10 is separated from the corresponding exhaust port 4. Instead, the air outlet 7 corresponds to the exhaust port 4 one by one. At this time, the cooperation between the air outlet 7 and the exhaust port 4 enables the heat in the regulated power supply box 1 to be discharged more efficiently, thereby making the regulated power supply cool down faster, being protected more timely. After the exhaust temperature returns to normal, the electric push rod 6 pushes the moving frame 5 to reset, so that each component returns to the initial state.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present invention.
