具体实施方式 detailed description

下面结合附图和具体实施方式对本实用新型做进一步的描述。 Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.

如图1、图2所示的实施例中,一种电梯变频器壳体结构,包括主壳体1,主壳体包括上壳盖11、上端开口的下壳体12,上壳盖封住下壳体的上端开口且与下壳体之间可拆卸连接,所述主壳体内设有竖隔板2、导气管3,竖隔板将主壳体内部分隔成电路腔1a、进气腔1b,下壳体上设有壳进气孔1c,主壳体上设有至少一个与电路腔连通的壳排气孔1d,进气腔内设有呈圆台状的旋风锥筒4,旋风锥筒上、下端均开口且上端开口大于下端开口,旋风锥筒上设有用于向旋风锥筒内切向进气的切向进气管41,切向进气管一端连通旋风锥筒,切向进气管另一端连通壳进气孔,导气管一端处在电路腔内,导气管另一端穿过竖隔板且与进气腔内部连通,导气管处在进气腔内的一端与旋风锥筒上端开口对接,导气管内设有由电机带动的导风叶轮31,导风叶轮的导风方向为由导气管至电路腔。所述旋风锥筒内设有过滤网筒42,过滤网筒将切向进气管与旋风锥筒上端开口之间隔开,过滤网筒上设有多个过滤孔。电路腔中用于安装固定各种电路电子元件。 In the embodiment shown in Fig. 1, Fig. 2, a kind of elevator frequency converter casing structure, comprises main casing 1, and main casing comprises upper casing cover 11, the lower casing 12 of upper end opening, and upper casing cover seals The upper end of the lower housing is open and detachably connected with the lower housing. The main housing is provided with a vertical partition 2 and an air duct 3. The vertical partition divides the interior of the main housing into a circuit chamber 1a and an air intake chamber. 1b, the lower casing is provided with a casing air inlet 1c, the main casing is provided with at least one casing exhaust hole 1d communicating with the circuit chamber, and the air inlet chamber is provided with a cyclone cone 4 in the shape of a circular frustum, and the cyclone cone The upper and lower ends of the barrel are open and the opening at the upper end is larger than the opening at the lower end. The cyclone cone is provided with a tangential air intake pipe 41 for tangential air intake into the cyclone cone. One end of the tangential air intake pipe is connected to the cyclone cone. The other end is connected to the air inlet of the shell, one end of the air guide tube is in the circuit cavity, the other end of the air guide tube passes through the vertical partition and communicates with the inside of the air intake cavity, and the end of the air guide tube in the air intake cavity is open to the upper end of the cyclone cone Docking, the air guiding impeller 31 driven by the motor is arranged in the air guiding pipe, and the air guiding direction of the air guiding impeller is from the air guiding pipe to the circuit chamber. A filter screen tube 42 is arranged inside the cyclone cone tube, and the filter screen tube separates the tangential air intake pipe from the upper opening of the cyclone cone tube, and the filter screen tube is provided with a plurality of filter holes. The circuit cavity is used to install and fix various circuit electronic components.

外部空气中不可避免会具有灰尘杂质,在导风叶轮的作用下,外部空气由壳进气孔、切向进气管,以切向或近似切向的方式进入到旋风锥筒内,并在旋风锥筒内形成旋流,相对较重(较大)的灰尘杂质贴壁,随后由于重力逐渐落下,空气气流则通过各过滤孔进入尘杯内(若无过滤网筒结构,则空气气流会从中部回压,向上达到旋风锥通上端开口),并向上达到旋风锥通上端开口,随后经导气管达到电路腔内,对电路腔内的电路电子元件进行冷却散热,并最终从壳排气孔排出。如此一来,利用导风叶轮可进行强力有效的导风散热,且散热气流被物理性净化,可以极大减少电路电子元件的积灰,防止积灰过多而导致的散热能力差。 There will inevitably be dust and impurities in the external air. Under the action of the wind guide impeller, the external air enters the cyclone cone in a tangential or approximately tangential way from the shell air inlet and the tangential air intake pipe, and is discharged in the cyclone. A swirling flow is formed in the cone, relatively heavy (bigger) dust and impurities adhere to the wall, and then gradually fall due to gravity, and the air flow enters the dust cup through the filter holes (if there is no filter mesh structure, the air flow will flow from Back pressure in the middle, upward to the upper opening of the cyclone cone), and upward to the upper opening of the cyclone cone, and then to the circuit cavity through the air duct, cooling and heat dissipation of the circuit electronic components in the circuit cavity, and finally through the exhaust hole of the shell discharge. In this way, the wind guide impeller can be used to conduct strong and effective air guide and heat dissipation, and the heat dissipation airflow is physically purified, which can greatly reduce the dust accumulation of electronic components in the circuit, and prevent poor heat dissipation caused by excessive dust accumulation.

所述下壳体的底板包括底板本体、封盖板121,底板本体上设有与封盖板对应的封板孔,封盖板处在封板孔中且与底板本体之间卡接,封盖板完全封住旋风锥筒下端开口。工作一段时间后,无需进行内部结构的拆卸,直接取下封盖板就可实现灰尘杂质的倾倒、清理。 The bottom plate of the lower housing includes a bottom plate body and a cover plate 121. The base plate body is provided with a cover plate hole corresponding to the cover plate, and the cover plate is located in the cover plate hole and is clamped with the base plate body. The cover plate completely seals the opening at the lower end of the cyclone cone. After working for a period of time, there is no need to disassemble the internal structure, and the dust and impurities can be dumped and cleaned by directly removing the cover plate.

所述旋风锥筒内设有一上、下端均开口的内灰筒43,过滤网筒下端设有落灰口,内灰筒上端开口与落灰口对接,内灰筒下端设有用于封住内灰筒下端开口的底盖44,底盖与内灰筒下端开口之间螺纹连接。内灰筒外部相当于大灰仓,里面一般是“粗灰”(大颗粒灰尘杂质),内灰筒内部则是“细灰”(小颗粒灰尘杂质)。当需要进行内灰筒内部灰尘杂质的倾倒、清理时,可以直接旋下底盖进行处理,方便快捷。而且“粗灰”、“细灰”分开,有利于回收和后处理。 The cyclone cone tube is provided with an inner ash tube 43 with both upper and lower ends open. The lower end of the filter screen tube is provided with an ash drop port. The bottom cover 44 of the lower end opening of the ash tube is threadedly connected between the bottom cover and the lower end opening of the inner ash tube. The outside of the inner ash tank is equivalent to a large ash bin, and the inside is generally "coarse ash" (large particle dust impurities), and the inside of the inner ash tank is "fine ash" (small particle dust impurities). When it is necessary to dump and clean the dust and impurities inside the inner ash tank, the bottom cover can be directly unscrewed for processing, which is convenient and quick. Moreover, the separation of "coarse ash" and "fine ash" is beneficial to recycling and post-processing.

所述上壳盖与下壳体之间互相卡接或通过螺钉固定。方便拆卸、更换、清理和维护。 The upper case cover and the lower case are engaged with each other or fixed by screws. It is convenient for disassembly, replacement, cleaning and maintenance.
