Description

Technical Field

[0001] This utility model relates to the field of DC power supply technology, specifically a novel multifunctional integrated DC power supply. Background Technology

[0002] A DC power supply unit is a device commonly used to provide DC power to control, protection, and signaling equipment in a power system. Traditional DC power supplies have relatively simple functions, usually only having basic charging and power supply functions, which cannot meet the needs of modern power systems for multi-functional equipment.

[0003] For example, the charging module is one of the core components of a DC power supply. During the process of converting AC power to DC power, it will generate heat due to energy conversion losses. In particular, the charging module using high-frequency switching power supply technology has a large power output when working, and the heat generation phenomenon is more obvious.

[0004] In existing technologies, the combination of fans and heat dissipation holes is widely used in the heat dissipation design of DC power supply screens. However, during operation, the fan inevitably brings dust from the external environment into the DC power supply screen. Over time, a large amount of dust will gradually accumulate on the surface of internal components, which will not only significantly reduce the heat dissipation efficiency of the components and cause the operating temperature of the components to rise, but also easily have a negative impact on the electrical performance of the components and increase the probability of circuit failure. Utility Model Content

[0005] The purpose of this invention is to provide a novel multifunctional integrated DC power supply to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel multifunctional integrated DC power supply, comprising:

[0007] The DC power supply unit and the heat dissipation mechanism connected to its bottom are used to cool the interior of the DC power supply unit.

[0008] The heat dissipation mechanism includes a water tank installed at the bottom of the DC power supply body. The bottom of the DC power supply body has ventilation holes, and the top of the water tank has a rectangular opening. The water tank and the DC power supply body are connected through the ventilation holes and the rectangular opening.

[0009] The water tank is equipped with a heat dissipation component that runs through it to cool the interior of the DC power supply unit.

[0010] Preferably, the heat dissipation assembly includes a mounting cavity opened at the top of the water tank cavity, and a cooling fan is installed inside the mounting cavity and at the bottom of the rectangular opening;

[0011] Ventilation openings are provided on both sides of the top of the water tank, and air ducts are installed on both sides of the top of the water tank. The mounting cavity is connected to the air ducts through the ventilation openings. A circulation port is provided at the top between the two air ducts, and the air ducts are connected to both sides of the DC power supply body through the circulation port.

[0012] Preferably, condenser pipes are installed through both sides inside the water tank, and the tops of the two condenser pipes pass through vents and extend into the interior of the air duct.

[0013] A condenser pump is installed on one side inside the water tank. The outlet of the condenser pump is connected to a first connecting pipe. The end of the first connecting pipe away from the condenser pump passes through the water tank and extends to the bottom of the water tank cavity. The end of the first connecting pipe inside the water tank is connected to a T-connector, and both ends of the T-connector are connected to second connecting pipes. The end of the second connecting pipe away from the T-connector is connected to the end of the condenser pump inside the water tank. The inlet of the condenser pump is connected to a third connecting pipe. One end of the third connecting pipe passes through the water tank and extends to the bottom of the water tank cavity.

[0014] Preferably, each of the two air ducts has a bracket fixedly installed inside, and fan blades are rotatably installed on both sides of the top of the bracket.

[0015] Preferably, a filter plate is fixedly installed inside the circulation port to filter dust in the air inside the DC power supply unit.

[0016] Preferably, a vertical pipe is installed through one side of the top of the water tank, and the bottom end of the vertical pipe penetrates the water tank and extends to the bottom of the inner cavity of the water tank for adding water to the inside of the water tank.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By utilizing the heat dissipation mechanism, when the internal temperature of the DC power supply unit is too high, the cooling fan blows the gas inside the DC power supply unit into the mounting cavity through the connection between the rectangular opening and the ventilation hole. Furthermore, through the connection between the ventilation hole and the air duct, the gas is continuously blown into the air duct by the cooling fan, and heat is exchanged with the heated gas through the condenser tube inside the air duct. The cooled gas is then reinjected into the DC power supply unit through the circulation port between the air duct and the DC power supply unit. This achieves internal air circulation within the DC power supply unit, preventing external air from entering and simultaneously cooling the unit to avoid excessively high internal temperatures affecting the internal components.

[0019] 2. When the gas inside the DC power supply unit enters the duct, the condenser pump operates to draw condensate from the water tank and delivers it to the second connecting pipe through the connection between the first connecting pipe and the tee pipe. The coolant is then injected into the condenser pipe through the connection between the second connecting pipe and the condenser pipe to exchange heat with the high-temperature gas entering the duct. This achieves cooling and heat dissipation of the DC power supply unit, preventing the internal components from being damaged due to excessively high internal temperature.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 This utility model provides a technical solution: a novel multifunctional integrated DC power supply, comprising:

[0028] The DC power supply body 1 and the heat dissipation mechanism 2 connected to its bottom are used to cool the interior of the DC power supply body 1.

[0029] The heat dissipation mechanism 2 includes a water tank 21 installed at the bottom of the DC power supply body 1. A ventilation hole 22 is provided at the bottom of the DC power supply body 1, and a rectangular opening 23 is provided at the top of the water tank 21. The water tank 21 and the DC power supply body 1 are connected through the ventilation hole 22 and the rectangular opening 23.

[0030] A heat dissipation component 24 is installed through the interior of the water tank 21 to cool the interior of the DC power supply unit 1.

[0031] Reference Figure 2 , Figure 3 as well as Figure 4 As shown, the heat dissipation assembly 24 includes a mounting cavity 241 opened at the top of the inner cavity of the water tank 21, and a cooling fan 242 is installed inside the mounting cavity 241 and at the bottom of the rectangular opening 23.

[0032] Ventilation openings 243 are provided on both sides of the top of the water tank 21, and air ducts 244 are installed on both sides of the top of the water tank 21. The mounting cavity 241 is connected to the air ducts 244 through the ventilation openings 243. A circulation port 245 is provided at the top between the two air ducts 244, and the air ducts 244 are connected to both sides of the DC power supply main body 1 through the circulation port 245. Condensing pipes 246 are installed through both sides inside the water tank 21, and the tops of the two condensing pipes 246 penetrate through the ventilation openings 243 and extend into the interior of the air ducts 244.

[0033] In this embodiment, the cooling fan 242 blows the gas inside the DC power supply unit 1 into the mounting cavity 241 through the connection between the rectangular opening 23 and the ventilation hole 22. Utilizing the connection between the ventilation hole 243 and the air duct 244, the gas is continuously blown into the air duct 244 by the cooling fan 242. The condenser 246 inside the air duct 244 exchanges heat with the heated gas. Then, the cooled gas is reinjected into the DC power supply unit 1 through the circulation port 245 between the air duct 244 and the DC power supply unit 1. This achieves internal air circulation inside the DC power supply unit 1, preventing external air from entering and simultaneously cooling the air to avoid excessively high internal temperatures affecting the internal components.

[0034] Reference Figure 3 as well as Figure 5As shown, a condenser pump 247 is installed on one side inside the water tank 21. The outlet end of the condenser pump 247 is connected to a first connecting pipe 248. The end of the first connecting pipe 248 away from the condenser pump 247 passes through the water tank 21 and extends to the bottom of the inner cavity of the water tank 21. The end of the first connecting pipe 248 inside the water tank 21 is connected to a three-way pipe 249. Both ends of the three-way pipe 249 are connected to a second connecting pipe 2401. The end of the second connecting pipe 2401 away from the three-way pipe 249 is connected to the end of the condenser pipe 246 inside the water tank 21. The inlet end of the condenser pump 247 is connected to a third connecting pipe 2402. One end of the third connecting pipe 2402 passes through the water tank 21 and extends to the bottom of the inner cavity of the water tank 21.

[0035] In this embodiment, when gas enters the air duct 244 inside the DC power supply body 1, the condenser pump 247 operates to draw condensate from the water tank 21 and transports it to the inside of the second connecting pipe 2401 through the connection between the first connecting pipe 248 and the three-way pipe 249. The coolant is then injected into the condenser pipe 246 through the connection between the second connecting pipe 2401 and the condenser pipe 246 to exchange heat with the high-temperature gas entering the air duct 244. This achieves cooling and heat dissipation inside the DC power supply body 1, preventing the internal components of the DC power supply body 1 from being damaged due to excessively high internal temperature.

[0036] Reference Figure 4 As shown, brackets 2404 are fixedly installed inside both air ducts 244, and fan blades 2405 are rotatably installed on both sides of the top of the brackets 2404.

[0037] In this embodiment, when the wind enters the interior of the duct 244, the wind drives the fan blades 2405 to rotate, thereby accelerating the airflow speed inside the duct 244 and enhancing the ventilation effect.

[0038] Reference Figure 4 As shown, a filter plate 2406 is fixedly installed inside the circulation port 245 to filter dust in the air inside the DC power supply unit 1.

[0039] Reference Figure 3 As shown, a vertical pipe 2407 is installed through one side of the top of the water tank 21. The bottom end of the vertical pipe 2407 passes through the water tank 21 and extends to the bottom of the inner cavity of the water tank 21 for adding water to the inside of the water tank 21.

[0040] Working principle: When the temperature inside the DC power supply unit 1 is too high, the cooling fan 242 blows the gas inside the DC power supply unit 1 into the mounting cavity 241 through the connection between the rectangular opening 23 and the ventilation hole 22. With the connection between the ventilation hole 243 and the air duct 244, the gas enters the air duct 244 with the continuous blowing of the cooling fan 242. The gas with temperature is exchanged with the condenser 246 inside the air duct 244. Then, the cooled gas is reinjected into the DC power supply unit 1 through the circulation port 245 opened between the air duct 244 and the DC power supply unit 1.

[0041] Furthermore, when the gas inside the DC power supply unit 1 enters the air duct 244, the condenser pump 247 operates to draw condensate from the water tank 21 and transports it to the inside of the second connecting pipe 2401 through the connection between the first connecting pipe 248 and the three-way pipe 249. The coolant is then injected into the condenser pipe 246 through the connection between the second connecting pipe 2401 and the condenser pipe 246 to exchange heat with the high-temperature gas entering the air duct 244. This cools and dissipates heat from the inside of the DC power supply unit 1, preventing the internal temperature of the DC power supply unit 1 from becoming too high and affecting its internal components.
