Description
本發明是關於一種改良式恆溫恆濕測試設備,且特別是關於一種透過控制氣流,使測試區域具有較佳之溫度及流場均勻性的改良式恆溫恆濕測試設備。 The present invention relates to an improved constant temperature and humidity testing apparatus, and more particularly to an improved constant temperature and humidity testing apparatus for controlling a gas flow to provide a preferred temperature and flow field uniformity in a test area.
隨著時代的進步,各種電子裝置日益貼近人們的生活,已成為人們生活中密不可分的一環,帶給我們生活上很大的方便。但是,這些電子裝置(如:數位相機)很容易受到空間中過高的溫度及濕度而減少使用壽命,甚至出現使用中當機無法操作等現象。因此,這些電子裝置在設計時需經過一系列的環境測試驗證,才能確保其功能在不同使用環境上都能保持正常。 With the advancement of the times, various electronic devices have become closer to people's lives, and have become an inseparable part of people's lives, bringing us great convenience in life. However, these electronic devices (such as digital cameras) are susceptible to excessive temperature and humidity in the space to reduce the service life, and even in the event of inoperability. Therefore, these electronic devices are designed to undergo a series of environmental test verifications to ensure that their functions remain normal in different environments.
為了可以測試這些電子裝置,市面上提供有傳統式的恆溫恆濕測試箱,如圖1所示,圖1所繪示為習知之恆溫恆濕測試箱之示意圖。使用者可將電子裝置放置於恆溫恆濕測試箱內之測試空間11,該測試空間11的周圍環繞著對流之氣流,且此氣流會藉由加熱裝置12與冷卻裝置13來控制其溫度與濕度,讓電子裝置在特定環境溫度及濕度下進行測試。 In order to test these electronic devices, a conventional constant temperature and humidity test box is provided on the market, as shown in FIG. 1 , and FIG. 1 is a schematic view of a conventional constant temperature and humidity test box. The user can place the electronic device in the test space 11 in the constant temperature and humidity test box, the test space 11 is surrounded by the convective airflow, and the airflow is controlled by the heating device 12 and the cooling device 13 to control the temperature and humidity thereof. Let the electronic device test at a specific ambient temperature and humidity.
然而,傳統式的恆溫恆濕測試箱雖然能夠測試這些電子裝置。但是,其環繞於測試區域周圍之氣流並未進行整流,此對流方式會使氣流在改變方向時形成擾流,尤其是當氣流於端點處要轉彎時。所以傳統式的恆溫恆濕箱會產生至少多個區域的擾流(流場在此區域速度與溫度分布都會不均勻),故使氣流在恆溫恆濕測試箱內的流場均勻性不佳,進而導致溫度與濕度的控制效率不佳。 However, conventional constant temperature and humidity test chambers are capable of testing these electronic devices. However, the airflow around the test area is not rectified, and this convection mode causes the airflow to create a turbulence when changing direction, especially when the airflow is turning at the end point. Therefore, the conventional constant temperature and humidity chamber will generate at least a plurality of regions of the turbulence (the flow field in this region will be uneven in velocity and temperature distribution), so that the flow field uniformity in the constant temperature and humidity test chamber is not good. This in turn leads to poor control of temperature and humidity.
因此,如何改善恆溫恆濕測試箱內氣流之流場與溫度的均勻性,便是本領域具有通常知識者值得去思量地。 Therefore, how to improve the uniformity of the flow field and temperature of the gas flow in the constant temperature and humidity test chamber is worthy of consideration in the field.

The convection is carried out.

此外,請繼續參閱圖2。上述之第一風道241包括一第一加熱器241A及一第一空氣整流器241B,第一加熱器241A用來調節於第一風道241內之氣流,使氣流達到適當的溫度,而第一空氣整流器241B適於調整於第一風道241內之氣流。 更詳細的說,是將風機模組22所提供較為不穩定之氣流整流成更穩定的氣流。相對的。第二風道243包括一第二加熱器243A及一第二空氣整流器243B。第二加熱器243A用來調節於第二風道243內之氣流溫度(與上述之第一加熱器241A具有相同之功效),而第二空氣整流器243B用來調整於第二風道243內之氣流(與上述之第一空氣整流器241B具有相同之功效)。 In addition, please continue to see Figure 2. The first air channel 241 includes a first heater 241A and a first air rectifier 241B. The first heater 241A is configured to adjust the airflow in the first air channel 241 to bring the airflow to an appropriate temperature. The air rectifier 241B is adapted to adjust the air flow within the first air passage 241. In more detail, the relatively unstable airflow provided by the fan module 22 is rectified into a more stable airflow. relatively. The second air passage 243 includes a second heater 243A and a second air rectifier 243B. The second heater 243A is configured to adjust the temperature of the airflow in the second air passage 243 (having the same effect as the first heater 241A described above), and the second air rectifier 243B is used to adjust the airflow in the second air passage 243.

再者,第一風道241是連接於測試區域246之上方,而第二風道243是連接於測試區域246之下方。也就是說,在進行降溫時,氣流所流動的方向是由第一風道往第二風道流動,冷空氣會先經由冷卻模組245進行溫度的冷卻後,再由測試區域246上方往測試區域246下方流動,利用冷空氣下沉的特性增加測試區域246的均溫性;反之,進行升溫時,氣流所流動的方向是由第二風道往第一風道流動,熱空氣由下往上通過測試區域246,利用熱空氣會上升的特性增加測試區域的均溫性,而測試區域246便是改良式恆溫恆濕測試設備2放置待測物的區域。加濕模組244是設置於第一風道241內,且加濕模組244適於調整第一風道241中氣流的濕度。如此一來,能夠控制於測試區域246內的濕度與溫度,提供一個良好的測試環境。 Furthermore, the first air duct 241 is connected above the test area 246, and the second air duct 243 is connected below the test area 246. That is to say, when cooling is performed, the direction in which the airflow flows is from the first air passage to the second air passage, and the cold air is first cooled by the cooling module 245, and then tested by the test area 246. Flowing under the region 246, the cooling property of the cold air is used to increase the temperature uniformity of the test region 246; conversely, when the temperature is raised, the flow direction of the airflow is from the second air passage to the first air passage, and the hot air flows from the bottom to the Through the test area 246, the temperature uniformity of the test area is increased by the characteristic that the hot air rises, and the test area 246 is the area where the modified constant temperature and humidity test apparatus 2 places the object to be tested. The humidifying module 244 is disposed in the first air duct 241, and the humidifying module 244 is adapted to adjust the humidity of the airflow in the first air duct 241. As such, the humidity and temperature within the test zone 246 can be controlled to provide a good test environment.

The airflow is formed when it is cooled.
接著,氣流於加熱狀態時之對流方式。其中,風向調整器242為一第二角度位置,第二風口242B、第三風口242C、第四風口242D、及第六風口242F為開啟狀態,而第一風口242A及第五風口242E為閉合狀態,是氣流由第二風道243往第一風道241流動,請同時參閱圖5A及圖5B,圖5A所繪示為氣流於加熱狀態時對流之示意圖,圖5B所繪示為加熱狀態時之氣流於風向調整器內對流之示意圖。首先,藉由出風管232自風機模組22將氣流傳送至風向調整器242(第四風口242D),並將氣流傳送至第二空氣緩衝器243C(第二風口242B),且藉由第二空氣緩衝器243C來調整氣流速度的均勻性。此時,準備通過測試區域246下方之氣流便為均勻速度之氣流,並會通過第二加熱器243A來提高氣流的溫度。且透過第二空氣整流器243B,將氣流整流成穩定的氣流。之後,氣流會經由第一風道241傳送至風向調整器242(第六風口242F),並透過回風管231將氣流傳送回風機模組22(第三風口242C),便形成於加熱狀態時的氣流循環。 Then, the convection mode of the airflow in the heated state. The wind direction adjuster 242 is in a second angular position, and the second air outlet 242B, the third air outlet 242C, the fourth air outlet 242D, and the sixth air outlet 242F are in an open state, and the first air outlet 242A and the fifth air outlet 242E are in a closed state. The airflow flows from the second air passage 243 to the first air passage 241. Please refer to FIG. 5A and FIG. 5B simultaneously.

Thereafter, the airflow is transmitted to the wind direction adjuster 242 (the sixth air outlet 242F) via the first air passage 241, and the airflow is transmitted back to the fan module 22 (the third air outlet 242C) through the return air duct 231, and is formed in the heating state. The airflow loops.
此外,當氣流經過第一風道241時,便會分別透過加濕模組244以及冷卻模組245來調整氣流的濕度與溫度,並將氣流傳送回風機模組22。更詳細的說,冷卻模組245能依據氣流之冷卻及加熱的需求調整氣流溫度,加濕模組244則提供所需的濕度調整,來控制氣流的濕度變化,且氣流於內殼體24內對流便會經過整流(溫度、濕度、流場均勻性的調整),讓氣流能夠維持在穩定的狀態下進行對流。如此一來。便使氣流能夠具有較佳的均溫性以及均流性,使得測試區域246能夠有更好的溫度及流場均勻性。 In addition, when the airflow passes through the first air duct 241, the humidity and temperature of the airflow are adjusted through the humidifying module 244 and the cooling module 245, respectively, and the airflow is transmitted back to the fan module 22.

In this way, the airflow does not need to pass through the wind direction adjuster 242 to change direction, so that it has the effect of changing the convection direction of the airflow, so that the airflow can be convected through the first air duct 241 or the second air duct 243, respectively. When the fan module rotates in a first rotation direction, the airflow can be flowed from the first air passage to the second air passage. When the fan module rotates in a second rotation direction, the airflow can be The second air passage flows to the first air passage.
綜上所述,相較於習知之恆溫恆濕測試箱,本實施例之改良式恆溫恆濕測試設備2具有較佳的均溫均流效果,藉由空氣整流器與空氣緩衝器能調整氣流流場的均勻性。如此一來,氣流便能夠具有較佳的均溫性及均流性,使內殼體24內能夠有更好的溫度及流場均勻性。 In summary, the improved constant temperature and humidity test apparatus 2 of the present embodiment has a better average temperature and current sharing effect than the conventional constant temperature and humidity test chamber, and the air flow can be adjusted by the air rectifier and the air buffer. The uniformity of the field. In this way, the airflow can have better temperature uniformity and current sharing, so that the inner casing 24 can have better temperature and flow field uniformity.
