Please refer to Figures 1 to 9. The embodiment of the present application provides an elevator control cabinet cooling device, including a control cabinet 1, an air intake device 2, an air outlet device 3, and an air intake fan 15. The control cabinet 1 is provided with an air intake hole 11 and an air outlet hole 12; the air intake device 2 is arranged outside the machine room wall 5, one side of the air intake device 2 is connected to the air intake hole 11 through a first connecting pipe 13, and the other side of the air intake device 2 is provided with an air intake pipe 21; the air outlet device 3 is arranged outside the machine room wall 5, and the air outlet device 3 includes an air outlet pipe 31, one end of the air outlet pipe 31 is connected to the air outlet hole 12 through a second connecting pipe 14, and the other end of the air outlet pipe 31 is connected to an air pump 32, and an exhaust pipe 33 is provided on the air pump 32; the air intake fan 15 is provided in the air intake hole 11.

Working principle and effect: a through hole is opened at the corresponding position of the wall, and a first connecting pipe 13 and a second connecting pipe 14 are arranged in the through hole. One end of the first connecting pipe 13 is connected to the air inlet 11, and the other end is connected to the air inlet device 2. One end of the second connecting pipe 14 is connected to the air outlet 12, and the other end is connected to the air outlet device 3. When in use, the air intake fan 15 in the air inlet 11 sucks the wind outside the machine room from the air intake duct 21 into the control cabinet 1, and then the hot air in the control cabinet 1 is pumped out of the machine room through the air pump 32, so as to realize the alternating circulation of air, thereby achieving the purpose of heat dissipation inside the control cabinet 1. The above technical scheme allows the hot air in the control cabinet 1 to be dissipated to the outside of the machine room through the connecting pipe in the wall, reducing the accumulation of hot air in the machine room, and the gas entering the control cabinet 1 comes from outside the machine room, which effectively avoids the influence of high temperature in the machine room on the heat dissipation effect inside the control cabinet 1.

In one embodiment, the elevator control cabinet cooling device further includes a condenser, which is connected to the air intake device 2. When in use, the air outside the wall is sucked into the control cabinet 1 from the air intake duct 21 through the air intake fan 15 provided in the air intake hole 11, and the condenser is connected to the air intake device 2, and the gas entering the air intake device 2 is cooled by the condenser, so that the air outside the wall forms cold air and then enters the control cabinet 1 to cool the inside of the control cabinet 1, and then the hot air inside the control cabinet 1 is extracted to the outside of the wall by the air extraction pump 32, so as to realize the alternating circulation of hot and cold air, thereby accelerating the heat dissipation inside the control cabinet 1.

In one embodiment, as shown in FIGS. 3 to 5 , the condenser includes a condenser tube 41, which is arranged between the air intake duct 21 and the air intake hole 11. When air is sucked into the air intake device 2, it first flows from the air intake duct 21 to the condenser tube 41 and then to the air intake hole 11. The condenser tube 41 includes a plurality of transverse tubes, which are arranged and distributed longitudinally, and the first and second ends of two adjacent transverse tubes are connected by a U-shaped tube, so that the condensed water cooled in the condenser can flow from the inlet of the condenser tube 41 through the plurality of transverse tubes and then flow back to the condenser through the outlet of the condenser tube 41 for recycling. The plurality of transverse tubes are arranged and distributed longitudinally, which increases the contact area between the air and the transverse tubes and enhances the cooling effect of the condenser tube 41 on the gas entering the air intake device 2.

Furthermore, the condenser is a component of the refrigeration system and a component of the entire evaporator system, and is a type of heat exchanger. Condensers can be divided into three types according to their cooling form: water-cooled, air-cooled, evaporative and water-spraying. The condenser is mainly used to discharge heat. It can convert gas or steam into liquid and release heat in a very fast way. Preferably, a shell-and-tube condenser can be used. The heat transfer area of the shell-and-tube condenser is 0.5-500 square meters, which can be customized according to demand. The shell-and-tube condenser has the following advantages: the cooling water is not polluted by secondary steam and can be recycled; because the water is in a closed cycle in the condenser, there is no water impact sound, unlike the cooling water used by the hydraulic ejector, which is exposed to the outside and has water impact sound; it is not restricted by the height of the space, and can be installed vertically or horizontally, unlike the atmospheric condenser which is limited by the height of the space (the installation height of the atmospheric condenser is above 10.5m); the cooling effect is not worse than that of the direct condenser, and it is easy to control automatically.

Preferably, the condenser may be a shell-and-tube heat exchanger of the preferred model SJ-LG.

In one embodiment, the control cabinet 1 is a wall-mounted control cabinet, which is used to install the control cabinet 1 on the inner wall of the machine room wall 5. The control cabinet 1 is installed on the wall in a wall-mounted manner, and an air inlet 11 and an air outlet 12 are provided on the inner wall of the control cabinet 1 that is in contact with the wall, and a through hole is opened at a corresponding position of the wall, and a first connecting pipe 13 and a second connecting pipe 14 are arranged in the through hole, one end of the first connecting pipe 13 is connected to the air inlet 11, and the other end is connected to the air inlet device 2, and one end of the second connecting pipe 14 is connected to the air outlet 12, and the other end is connected to the air outlet device 3. The connection length of the first connecting pipe 13 and the second connecting pipe 14 is reduced, the distance and time of gas flow in the pipeline are shortened, the gas flow rate is increased, and the heat dissipation effect is enhanced.

In one embodiment, as shown in Fig. 7, a filter device 22 is provided in the air intake duct 21. The filter device 22 is provided at the air intake end of the air intake duct 21 to prevent external dust and other impurities from being sucked into the control cabinet 1 to affect the operation of the control cabinet 1.

Furthermore, the filter device 22 can use a synthetic fiber filter. According to the different materials, the filter material is divided into four types: synthetic fiber filter, non-woven filter, glass fiber filter, activated carbon filter. In general filtering environments, synthetic fiber filter can completely replace non-woven and glass fiber to cover the entire series of coarse, medium and high efficiency filter products. Compared with other filter materials of the same level, it has the advantages of small resistance, light weight, large capacity, environmental protection (incineration), and moderate price. Polyester fiber is used as the main raw material, abbreviated as PET. Polyester fiber is made of polyethylene terephthalate, also known as synthetic fiber or polyester. The specific gravity of polyester fiber is 1.38; the melting point is 255-260℃, it starts to bond at 205℃, and the safe ironing temperature is 135℃; the water absorption is poor, only 0.4%; the breaking strength of the filament is 4.5-5.5 g/denier, and that of the staple fiber is 3.5-5.5 g/denier; the breaking elongation of the filament is 15-25%, and that of the staple fiber is 25-40%; the strength of high-strength fiber can reach 7-8 g/denier, and the elongation is 7.5-12.5%.

Furthermore, polyester has excellent wrinkle resistance, elasticity and dimensional stability, good electrical insulation, sunlight resistance, friction resistance, mildew resistance, good chemical resistance, and resistance to weak acids and weak alkalis. The industry calls it: chemical fiber, which can be divided into large chemical fiber and small chemical fiber. Large chemical fiber refers to polyester fiber produced from high-quality PET chips; small chemical fiber refers to fibers produced by some small and medium-sized manufacturers using recycled PET chips of poor quality.
