Description

具百葉窗機構之電氣箱冷卻裝置Electrical box cooling device with shutter mechanism

          本創作係有關於一種具百葉窗機構之電氣箱冷卻裝置,尤指一種可針對電氣箱內的氣流死角等缺失,進行風向調整之電氣箱冷卻裝置。The present invention relates to an electric box cooling device with a louver mechanism, and more particularly to an electric box cooling device capable of adjusting the wind direction for missing airflow angles in the electric box.

          按,工作母機等之電氣箱,為防止人員誤觸,於一般正常使用時,係將電氣箱門關閉,而使電氣箱形成封閉狀態,在工作母機作動過程中,電氣箱內之電氣元件係同時運作,以提供工作母機作動所需電源控制等,而於電氣元件運作時係會持續放出熱能,且電氣箱係關閉呈封閉狀態,故電氣元件會在封閉的電氣箱內累積產生高溫,該高溫係會造成電氣元件異常或損壞情形,因此,現有電氣箱通常會裝配有冷卻裝置,以將電氣箱內高溫移除。According to the electrical box of the working machine, in order to prevent accidental contact by personnel, in normal normal use, the electrical box door is closed, and the electrical box is closed. During the operation of the working machine, the electrical components in the electrical box are Simultaneous operation, in order to provide the power control required for the working machine to operate, and the thermal energy is continuously released during the operation of the electrical components, and the electrical box is closed, so that the electrical components will accumulate in the closed electrical box to generate high temperature. High temperatures can cause electrical components to be abnormal or damaged, so existing electrical boxes are often equipped with cooling devices to remove high temperatures inside the electrical box.

          現有電氣箱之冷卻裝置其提供冷風吹出之出風口大多僅設具有一護手網,當該冷卻裝置輸出冷風時,由該設具有護手網之出風口吹出,且冷風僅能朝固定水平方向吹送而出,另有一種直接在鈑金上加工成型為格子形狀開孔,其亦屬固定式出風口型態;然,採用此固定式出風口設計,在電氣箱內係可能會產生氣流死角,而無法對電氣箱內各個位置處之電氣元件進行有效冷卻,以致造成電氣箱內部份電氣元件仍可能會發生溫度過高損壞情形。In the existing cooling device of the electric box, most of the air outlets for supplying cold air are provided with only one hand net. When the cooling device outputs cold air, the air outlet with the hand net is blown out, and the cold air can only be directed to a fixed horizontal direction. Blowing out, another type is directly formed on the sheet metal into a lattice-shaped opening, which is also a fixed air outlet type; however, the fixed air outlet design may cause a dead space in the electrical box. It is impossible to effectively cool the electrical components at various positions in the electrical box, so that the electrical components inside the electrical box may still be damaged by excessive temperature.

          另請參閱我國公告第445915號[證書號第181450號]之「機台熱交換器創新構造」,其主要包括一機座、冷凝機構、風扇、濾網、板面等元件。其係利用板面下方的風扇將加工機其電氣箱內部的熱空氣抽入機座的冷凝機構中,以讓熱空氣經過旁邊的流通空間進入散熱片與冷凝管中,同時產生熱交換作用,使得電氣箱內部的熱空氣可以冷卻降溫,降溫之後的熱空氣,再經由排風口吹回到加工機之電氣箱內部,藉此循環作用,以持續冷卻電氣箱的內部熱空氣。然,該我國公告第445915號[證書號第181450號]之「機台熱交換器創新構造」其空氣經由排風口吹回到加工機之電氣箱時,亦僅是由固定方向吹出冷風,因此,仍屬於固定式出風口設計,其冷風吹出的方向無法調整,故仍未對電氣箱內氣流死角問題提出改善方針。Please also refer to the "Innovative Structure of Machine Heat Exchanger" in China Bulletin No. 445915 [Certificate No. 181450], which mainly includes components such as a base, a condensing mechanism, a fan, a filter, and a plate surface. The utility model uses the fan under the plate surface to draw the hot air inside the electric box of the processing machine into the condensing mechanism of the machine seat, so that the hot air passes through the side circulation space into the heat sink and the condensing pipe, and at the same time, heat exchange is performed. The hot air inside the electric box can be cooled and cooled, and the hot air after cooling is blown back to the inside of the electric box of the processing machine through the air outlet, thereby circulating to continuously cool the internal hot air of the electric box. However, in the "Innovative Structure of Machine Heat Exchanger" of China's Announcement No. 445915 [Certificate No. 181450], when air is blown back to the electrical box of the processing machine through the air vent, only cold air is blown from the fixed direction. It still belongs to the fixed air outlet design, and the direction of the cold air blowing cannot be adjusted. Therefore, the improvement policy of the airflow dead angle in the electrical box has not been proposed.

          緣是,本創作人有鑑於現有電氣箱其冷卻裝置於使用上仍有上述缺失,乃藉其多年於相關領域的製造及設計經驗和知識的輔佐,並經多方巧思,針對現有電氣箱其冷卻裝置進行研發改良,而研創出本創作。The reason is that the creator has the above-mentioned shortcomings in view of the use of the cooling device of the existing electrical box, and it has been assisted by many years of manufacturing and design experience and knowledge in related fields, and has been ingenuity for the existing electrical box. The cooling device was developed and improved, and the research was created.

          本創作係有關於一種具百葉窗機構之電氣箱冷卻裝置,其主要目的係為了提供一種可針對電氣箱內的氣流死角等缺失,進行風向調整之電氣箱冷卻裝置。The present invention relates to an electric box cooling device with a louver mechanism, the main purpose of which is to provide an electric box cooling device capable of adjusting the wind direction for missing airflow angles in the electric box.

          而為令本創作之技術手段及其所能達成之效果,能夠有更完整且清楚的揭露,茲詳細說明如下,請一併參閱揭露之圖式及圖號:In order to make the technical means of this creation and the effect it can achieve, it can be more completely and clearly disclosed. For details, please refer to the following diagrams and drawings:

          首先,請參閱第一〜三圖所示,為本創作之具百葉窗機構之電氣箱冷卻裝置,係主要由一冷卻裝置主體(1)、一百葉窗機構(2)、一動力源(3)、一驅動器(4)、一電源供應器(5)及一計時器(6)所組成;其中:First, please refer to the first to third figures. The electric box cooling device with the shutter mechanism is mainly composed of a cooling device body (1), a louver mechanism (2), a power source (3), a driver (4), a power supply (5) and a timer (6); wherein:

          該冷卻裝置主體(1),係主要於其上設有回風口(11)及出風口(12),並於其內部設有冷卻單元(13);The cooling device body (1) is mainly provided with a return air outlet (11) and an air outlet (12), and a cooling unit (13) is disposed therein;

          該百葉窗機構(2),係組設於該冷卻裝置主體(1)之出風口(12)處,乃設有上、下相鄰排列之葉片(21),並使該葉片(21)常態呈水平開啟角度,又於該葉片(21)組設有擺動調節單元(22);The louver mechanism (2) is disposed at the air outlet (12) of the main body (1) of the cooling device, and is provided with blades (21) arranged adjacent to each other, and the blade (21) is normally The horizontal opening angle is further provided with a swing adjusting unit (22) in the blade (21) group;

          該動力源(3),係為馬達,乃與該百葉窗機構(2)之擺動調節單元(22)相組接;The power source (3) is a motor that is coupled to the swing adjustment unit (22) of the shutter mechanism (2);

          該驅動器(4),係與該動力源(3)相耦接,該驅動器(4)係可以驅使動力源(3)作動;The driver (4) is coupled to the power source (3), and the driver (4) can drive the power source (3) to operate;

          該電源供應器(5),係與該驅動器(4)相耦接;The power supply (5) is coupled to the driver (4);

          該計時器(6),係為一計時電驛〔Timer Relay〕,乃主要於其外部設有一設定部(61),並使該設定部(61)與該計時器(6)內之計時部(62)相耦接,另使該計時器(6)與該電源供應器(5)相耦接。The timer (6) is a timer relay, and a setting unit (61) is mainly provided outside the setting unit (61), and the setting unit (61) and the timer unit in the timer (6) are provided. (62) coupled to each other, and the timer (6) is coupled to the power supply (5).

          據此,當組裝使用時,係將本創作裝配於工作母機等電氣箱(7)處,並使該冷卻裝置主體(1)之回風口(11)及出風口(12)與該電氣箱(7)內部相連通,於平時,冷卻裝置主體(1)內之冷卻單元(13)係會由出風口(12)經百葉窗機構(2)由呈常態水平開啟之葉片(21)處水平吹出冷風,以進入電氣箱(7)內部,並強制該電氣箱(7)內部的氣流開始循環流動,且將電氣箱(7)內複數個電氣元件(71)造成的熱空氣,透過該回風口(11)送回本創作之冷卻裝置主體(1)中進行降溫冷卻。當空氣變成冷空氣之後,再繼續由冷卻裝置主體(1)其出風口(12)通過百葉窗機構(2)而對電氣箱(7)內部吹出冷風。如此反覆強制循環電氣箱(7)內的空氣,以提供冷卻該電氣箱(7)內部空氣功效。Accordingly, when assembled and used, the creation is assembled at an electrical box (7) such as a working machine, and the air return port (11) and the air outlet (12) of the cooling device main body (1) and the electric box ( 7) The internal phase is connected. In normal times, the cooling unit (13) in the main body (1) of the cooling device is horizontally blown out by the air outlet (12) through the louver mechanism (2) from the blade (21) which is normally opened horizontally. To enter the inside of the electrical box (7), and to force the airflow inside the electrical box (7) to start circulating, and to pass the hot air caused by the plurality of electrical components (71) in the electrical box (7) through the return air outlet ( 11) Return to the main body (1) of the cooling device for cooling and cooling. After the air becomes cold air, the cold air is continuously blown into the inside of the electric box (7) by the air outlet (12) of the cooling device main body (1) passing through the louver mechanism (2). This repeatedly forces the air in the electrical box (7) to be circulated to provide the effect of cooling the internal air of the electrical box (7).

          再者,為避免產生氣流死角,而且欲使電氣箱(7)內的電氣元件(71)皆可受到冷風吹送降溫時,使用者即可由計時器(6)之設定部(61)進行導通電源時間與斷開電源時間的設定,例如:將電源導通時間設定為30秒,另將斷開的時間設定為30分鐘,則該計時器(6)驅動該電源供應器(5)一次供予驅動器(4)之電源時間為30秒,而每次供電間隔為30分鐘。Furthermore, in order to avoid the occurrence of airflow dead angles and to allow the electrical components (71) in the electrical box (7) to be cooled by the cold air, the user can turn on the power by the setting unit (61) of the timer (6). Time and power off time setting, for example, setting the power on time to 30 seconds and setting the disconnection time to 30 minutes, then the timer (6) drives the power supply (5) to the drive once. (4) The power supply time is 30 seconds, and the power supply interval is 30 minutes.

          當完成時間之設定後,即可啟動該計時器(6)之計時部(62)開始計時,當該計時部(62)計時30分鐘後,計時器(6)便輸出訊號予電源供應器(5),以供電予驅動器(4),再由驅動器(4)驅動該動力源(3),繼之,請一併參閱第四、五圖所示,動力源(3)係帶動相組接之百葉窗機構(2)其擺動調節單元(22)作動,以帶動百葉窗機構(2)其葉片(21)向下擺動,此時,由冷卻裝置主體(1)之出風口(12)經百葉窗機構(2)吹出之冷風,即會在呈向下角度之葉片(21)導引下,使冷風往下方吹送,如此一來,便可對位於電氣箱(7)下方位置之電氣元件(71)進行散熱降溫效果,以避免該葉片(21)只能保持常態水平位置時,電氣箱(7)內部氣流可能受到體積較大的電氣元件(71)阻礙,造成氣流死角,使較下方的電氣元件(71)無法散熱降溫損壞情形。When the completion time is set, the timer (62) of the timer (6) can be started to start timing. When the timer (62) is timed for 30 minutes, the timer (6) outputs a signal to the power supply ( 5), power is supplied to the driver (4), and then the power source (3) is driven by the driver (4). Then, as shown in the fourth and fifth figures, the power source (3) is driven to be connected. The louver mechanism (2) is operated by the swing adjusting unit (22) to drive the louver mechanism (2) to swing the blade (21) downward. At this time, the air outlet (12) of the cooling device main body (1) passes through the louver mechanism. (2) The cold air blown out is guided by the downwardly angled blade (21) to blow the cold air downward, so that the electrical component (71) located below the electrical box (7) can be used. The heat dissipation effect is to prevent the blade (21) from maintaining the normal horizontal position, and the internal airflow of the electrical box (7) may be obstructed by the bulky electrical component (71). Causes dead air, the more the lower the electrical component (71) can not damage the thermal cooling case.

          繼之,當計時器(6)之計時部(62)計算30秒後,計時器(6)便會驅使電源供應器(5)斷開提供給驅動器(4)的電源,此時,該驅動器(4)係會自動驅使動力源(3)帶動該百葉窗機構(2)的葉片(21)恢復到常態的水平位置,續之,當計時器(6)之計時部(62)再計算30分鐘後,該計時部(62)即會再驅使電源供應器(5)重新供電給驅動器(4)30秒,此時,若預先透過變更百葉窗機構(2)的位置或設計等方法,動力源(3)即可轉動,再經百葉窗機構(2)其擺動調節單元(22)帶動百葉窗機構(2)之葉片(21)向上擺動,以使由冷卻裝置主體(1)其出風口(12)經百葉窗機構(2)吹出冷風,在呈向上角度葉片(21)導引下,使冷風往上方吹送,以對位於電氣箱(7)較上方位置之電氣元件(71)進行散熱降溫,避免位於較上方電氣元件(71)過熱損壞。依此,藉由反覆透過計時器(6)經電源供應器(5)、驅動器(4)及動力源(3)驅使百葉窗機構(2)之葉片(21)自動向上、向下與呈常態水平位置擺動設計,即可進行導引冷卻裝置主體(1)吹進電氣箱(7)內之風向做不同角度變化,進而達到有效改善電氣箱(7)內氣流死角等缺失,以提高電氣箱(7)內電氣元件(71)之使用壽命等效果者。Then, when the timer (62) of the timer (6) is calculated for 30 seconds, the timer (6) drives the power supply (5) to turn off the power supplied to the driver (4). At this time, the driver (4) The system automatically drives the power source (3) to bring the blades (21) of the louver mechanism (2) back to the normal horizontal position, and then, when the timer (62) of the timer (6) is calculated for another 30 minutes. After that, the timing unit (62) re-energizes the power supply (5) to the driver (4) for 30 seconds. At this time, if the position or design of the shutter mechanism (2) is changed in advance, the power source ( 3) Rotate, and then the sway adjusting unit (22) of the louver mechanism (2) drives the blade (21) of the louver mechanism (2) to swing upward so that the air outlet (12) of the cooling device body (1) passes through The louver mechanism (2) blows cold air, and under the guidance of the upward angle blade (21), the cold air is blown upward to electrically locate the upper position of the electrical box (7). The component (71) performs heat dissipation to prevent overheating damage to the upper electrical component (71). Accordingly, the blade (21) of the louver mechanism (2) is automatically driven up, down, and normal by the power supply (5), the driver (4), and the power source (3) through the timer (6). The position swing design can make the wind direction of the main body (1) of the guiding cooling device blow into the electric box (7) to change at different angles, thereby effectively improving the lack of airflow dead angle in the electric box (7), thereby improving the electrical box ( 7) The effect of the service life of the internal electrical components (71).

          前述之實施例或圖式並非限定本創作之具百葉窗機構之電氣箱冷卻裝置實施樣態,本創作於實施上係可進一步控制百葉窗機構(2)其葉片(21)向上擺或向下擺之擺動幅度,而此擺動幅度係可依據該電氣箱(7)內電氣元件(71)佈置狀況進行調整,並透過對百葉窗機構(2)或驅動器(4)與動力源(3)機構設定進行調整即可,凡所屬技術領域中具有通常知識者所為之適當變化或修飾,皆應視為不脫離本創作之具百葉窗機構之電氣箱冷卻裝置專利範疇。The foregoing embodiments or drawings do not limit the implementation of the electric box cooling device with the louver mechanism of the present invention. The present invention can further control the louver mechanism (2) to swing the blade (21) upward or downward. The amplitude, which can be adjusted according to the arrangement of the electrical components (71) in the electrical box (7), and adjusted by the mechanism setting of the shutter mechanism (2) or the driver (4) and the power source (3) Any changes or modifications made by those of ordinary skill in the art may be considered as a patent for the electrical box cooling device without the louver mechanism of the present invention.

          綜上所述,本創作之實施例確能達到所預期功效,又其所揭露之具體構造,不僅未曾見諸於同類產品中,亦未曾公開於申請前,誠已完全符合專利法之規定與要求,爰依法提出新型專利之申請,懇請惠予審查,並賜准專利,則實感德便。In summary, the embodiment of the present creation can achieve the expected effect, and the specific structure disclosed therein has not been seen in the same kind of products, nor has it been disclosed before the application, and has fully complied with the provisions of the Patent Law.
