Description

Technical Field

[0001] The utility model relates to the technical field of power distribution room equipment, in particular to a heat dissipation and ventilation device for a power distribution room. Background Art

[0002] Existing power distribution rooms are all equipped with forced refrigeration measures such as air conditioners or fans. The adopted is internal circulation refrigeration to absorb the discharged heat and ensure the ambient temperature adaptable when low-voltage electrical equipment is working.

[0003] When transformers and frequency converters are working, they generate a large amount of heat, causing the temperature in the power distribution room to rise. When the air conditioner cooling fails to meet the room temperature requirement, it is not conducive to the safe operation of the equipment. Overheating of the power distribution equipment is prone to electrical fires and the risk of electrical protection tripping and power-off.

[0004] Due to the certain limitations of the forced refrigeration measures in the power distribution room, the heat released when high-power electrical equipment is working, especially in midsummer, the air conditioner cooling cannot ensure the ambient temperature suitable for the electrical equipment to work, and it is often at the critical value of temperature alarm.

[0005] At the same time, solid particles such as dust will bring great hidden dangers to the safe operation of electrical equipment. Therefore, when cooling the power distribution room, the impact of dust on the power distribution system must be considered. While taking away the heat, the impact of solid particles such as dust on the safe operation of the power distribution system should be reduced. Content of the Utility Model

Detailed implementation manners

[0026] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, detail the specific implementation manners, structures, features, and effects of the application according to the present utility model. In the following description, different "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. In addition, the specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0027] The present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] As Figure 1 and Figure 2 shown, a power distribution room heat dissipation and ventilation device provided by an embodiment of the present utility model includes: a housing 1 and an air circulation part;

[0029] A power distribution cabinet 2 is arranged inside the housing 1;

[0030] The air circulation part includes an air inlet duct 3 and an air outlet duct 4. The air inlet duct 3 and the air outlet duct 4 are respectively installed on opposite side walls of the housing 1. A filter cotton layer 5 and an elastic net 6 are sequentially installed inside the air inlet duct 3, and a plurality of impact balls 7 are arranged between the filter cotton layer 5 and the elastic net 6.

[0031] The working process of a power distribution room heat dissipation and ventilation device is as follows:

[0032] External air enters the housing 1 through the air inlet duct 3. The filter cotton layer 5 filters dust particles in the air, and the clean air flows out of the housing 1 through the air outlet duct 4, taking away the heat dissipated by the power distribution cabinet 2.

[0033] In the above process, the flowing air blows the plurality of impact balls 7, driving the plurality of impact balls 7 to move irregularly between the filter cotton layer 5 and the elastic net 6. The impact balls 7 collide with the filter cotton layer 5, and the dust particles attached to the filter cotton layer 5 gradually fall off. The impact balls 7 collide with the elastic net 6, and the elastic net 6 provides a resilience force for the impact balls 7, and the impact balls 7 collide with the filter cotton layer 5 again.

[0034] Through the above process, the filter cotton layer 5 is subjected to high-frequency impact vibration. While filtering dust particles, it also vibrates and shakes off the dust particles, so that the filter holes of the filter cotton layer 5 remain permanently unblocked.

[0035] In the technical solution of the present utility model, the device has a simple structure and can disperse the heat in the power distribution room and filter the external dust at the same time during a relatively long service life cycle.

[0036] Specifically, the elastic net 6 is made of wire mesh material.

[0037] Specifically, a filter cotton is also provided at the outlet end of the air outlet duct 4 to prevent external dust from flowing back into the housing 1 along the air outlet duct 4.

[0038] As Figure 1 shown, in the specific embodiment, it further includes an air collecting hood 8. An air inlet is provided on the side surface of the power distribution cabinet 2, and an air outlet 9 is provided on the top wall of the power distribution cabinet 2. The air collecting hood 8 covers the top wall of the power distribution cabinet 2. The side wall outlet of the air collecting hood 8 is connected to the air outlet duct 4, and an exhaust fan 10 is provided in the air collecting hood 8.

[0039] In this embodiment, specifically, the clean air entering the housing 1 enters the power distribution cabinet 2 from the air inlet. Driven by the exhaust fan 10, it enters the air collecting hood 8 from the air outlet 9 and flows out of the housing 1 along the air outlet duct 4. The clean air flows specifically over the surfaces of devices such as inverters in the power distribution cabinet 2 and takes away the heat generated by the operation of the devices in the first time.

[0040] Specifically, a filter cotton is installed at the air inlet of the power distribution cabinet 2.

[0041] As Figure 1 and Figure 2 shown, in the specific embodiment, one end of the air inlet duct 3 is fixedly connected to the side wall of the housing 1, and the other end of the air inlet duct 3 is located outside the housing 1. The other end of the air inlet duct 3 is bent obliquely downward. The filter cotton layer 5 and the elastic net 6 are sequentially installed inside the other end of the air inlet duct 3.

[0042] In this embodiment, specifically, the other end of the air inlet duct 3 is bent obliquely downward to prevent external dust and rainwater from naturally settling on the outer surface of the filter cotton layer 5. At the same time, the filter cotton layer 5 and the elastic net 6 are sequentially installed inside the other end of the air inlet duct 3. A plurality of impact balls 7 are in natural contact with the inner surface of the filter cotton layer 5. When the external air flows into the air inlet duct 3 from bottom to top, overcoming the gravity of the impact balls 7, the impact balls 7 are briefly away from the filter cotton layer 5 and then the elastic net 6 rebounds the impact balls 7 to impact the filter cotton layer 5.

[0043] As Figure 1As shown, in the specific implementation manner, it further includes an axial flow fan 11, and the axial flow fan 11 is installed at one end of the air inlet duct 3.

[0044] In this implementation manner, specifically, the axial flow fan 11 directly provides a pressure difference drive for the outside air to enter the housing 1, and at the same time ensures that the air flow impact force received by the impact ball 7 can enable the impact ball 7 to maintain continuous kinetic energy.

[0045] As Figure 1 shown, in the specific implementation manner, an indoor reserved port 12 is installed on the pipe wall of the air outlet duct 4.

[0046] In this implementation manner, specifically, the indoor reserved port 12 is located inside the housing 1. In winter, due to the relatively low outside temperature, the air outlet duct 4 guides a part of the hot air out of the housing 1, and another part of the hot air flow returns to the internal space of the housing 1 through the indoor reserved port 12 to prevent the temperature inside the housing 1 from being too low; in summer, the operator seals the indoor reserved port 12, and the air outlet duct 4 guides all the hot air flow in the power distribution cabinet 2 out of the housing 1.

[0047] As Figure 1 shown, in the specific implementation manner, it further includes a suspension rod 13. One end of the suspension rod 13 is connected to the top wall of the housing 1, and the other end of the suspension rod 13 is connected to the air outlet duct 4.

[0048] In this implementation manner, specifically, through the suspension rod 13, the weight of the air outlet duct 4 is borne by the top wall of the housing 1, avoiding bending and damage of the air outlet duct 4.

[0049] As Figure 1 and Figure 2 shown, in the specific implementation manner, it further includes a plurality of partition plates 14. The plurality of partition plates 14 are arranged in sequence between the filter cotton layer 5 and the elastic net 6, and are used to divide the space between the filter cotton layer 5 and the elastic net 6 into a plurality of independent spaces. The plurality of impact balls 7 are evenly distributed in the plurality of independent spaces.

[0050] In this implementation manner, specifically, each partition plate 14 is perpendicular to the filter cotton layer 5 and the elastic net 6 respectively, and there are several impact balls 7 in each independent space, ensuring that the local area of the filter cotton layer 5 corresponding to each independent space can receive the collision of the impact balls 7, so as to ensure that the entire area of the filter cotton layer 5 vibrates at a high frequency and shakes off the surface dust.

[0051] In the specific implementation manner, the impact ball 7 is made of plastic material, and the surface of the impact ball 7 is evenly distributed with multiple pits.

[0052] In this embodiment, specifically, the impact ball 7 is made of unsaturated polyester resin plastic, which is light in weight and high in strength. The surface of the impact ball 7 is evenly distributed with a plurality of pits, which increases the roughness of the surface of the impact ball 7, so that the stress conditions on the surfaces of the pits of the impact ball 7 are different, and the directions of the resultant forces received by the plurality of impact balls 7 are also different, improving the degree of chaos of the movement directions of the plurality of impact balls 7, so that the directions of the impact forces of the impact balls 7 received at different positions of the filter cotton layer 5 are different, facilitating the full removal of dust in the filter holes of the filter cotton layer 5.

[0053] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
