圖1是根據本案的一個實施例的燒結設備100的正視圖,以示出燒結設備100方塊圖示意結構。如圖1所示,燒結設備100包括烘乾段101、燒結段102、降溫延滯段103和冷卻段104。待加工的光伏裝置由傳送帶運輸,依次經過烘乾段101、燒結段102、降溫延滯段103和冷卻段104後完成燒結加工。FIG. 1 is a front view of a
烘乾段101中設有烘乾段加熱部件111,烘乾段加熱部件111提供烘乾段烘乾溫度。烘乾段101中的烘乾段加熱部件111以烘乾段烘乾溫度對將光伏裝置進行加熱,使光伏裝置在離開烘乾段101時加熱至烘乾段預設溫度,以使得光伏裝置上的有機溶劑揮發,經過烘乾處理後的光伏裝置進入燒結段102。The
燒結段102中設有燒結段加熱部件112,燒結段加熱部件112提供燒結段燒結溫度。燒結段102中的燒結段加熱部件112以燒結段燒結溫度對光伏裝置進行加熱,使光伏裝置加熱至燒結段預設溫度,即光伏裝置從燒結段102輸出時的溫度,以對光伏裝置進行燒結處理。光伏裝置的燒結段預設溫度通常大於600度。The
經過燒結處理後的光伏裝置進入降溫延滯段103。降溫延滯段103中設有降溫延滯段加熱部件113,降溫延滯段加熱部件113提供降溫延滯段加熱溫度。降溫延滯段103的降溫延滯段加熱部件113將降溫延滯段加熱溫度施加到光伏裝置,以使得光伏裝置達到降溫延滯段預設溫度,即光伏裝置從降溫延滯段103輸出時的溫度。其中降溫延滯段加熱溫度低於燒結段燒結溫度並且低於燒結段預設溫度。降溫延滯段預設溫度低於或等於降溫延滯段加熱溫度。由於降溫延滯段加熱溫度低於燒結段燒結溫度和燒結段預設溫度,因此,雖然降溫延滯段103提供的是加熱溫度,但是進入降溫延滯段103的具有燒結段預設溫度的光伏裝置在降溫延滯段103中實際上進行了降溫,並且相對於將光伏裝置從燒結段102直接輸入冷卻段104來說,這種降溫速率是被延滯或被阻止的。換句話說,降溫延滯段103能夠使得剛從燒結段102出來的具有較高溫度的光伏裝置以較慢的速度降溫,使得光伏裝置以降低的降溫速率降到想要的溫度。The photovoltaic device after the sintering process enters the
從降溫延滯段103出來的光伏裝置進入冷卻段104,冷卻段104能夠對光伏裝置提供冷卻段冷卻溫度,以使得光伏裝置達到冷卻段預設溫度,即光伏裝置從冷卻段104輸出時的溫度。該冷卻段預設溫度低於降溫延滯段預設溫度。冷卻段預設溫度通常為40-80度。冷卻段104能夠使得光伏裝置以較快、不延滯或未被阻止的速度降溫。作為一個實施例,冷卻段104設置有冷卻設備,而不設有加熱設備。冷卻設備可以是風冷設備(例如,風扇)及/或水冷設備。當冷卻設備是風冷設備時,冷卻段104中的冷卻溫度大體上為大氣環境溫度。當冷卻設備是水冷設備時,冷卻段104中的冷卻溫度低於大氣環境溫度。The photovoltaic device from the
需要說明的是,雖然圖1中未示出,但烘乾段101、燒結段102、降溫延滯段103和冷卻段104中設有連通的傳送通道。傳送帶設置在傳送通道中。光伏裝置放置在傳送帶上。當傳送帶運行時,光伏裝置能夠依次通過烘乾段101、燒結段102、降溫延滯段103和冷卻段104。It should be noted that, although not shown in FIG. 1 , the
圖2A是圖1所示的燒結設備100的降溫延滯段103的立體圖。圖2B是圖2A所示的燒結設備100的降溫延滯段103的側視圖。如圖2A-2B所示,降溫延滯段103包括支撐架210、上爐膛201和下爐膛202。上爐膛201和下爐膛202由支撐架210支撐從而保持在預定位置。上爐膛201的一部分與下爐膛202的一部分之間設有間距,以形成傳送通道203。在本案的示例中,降溫延滯段103設有左右兩個並排的傳送通道203。降溫延滯段103的傳送通道203的入口與燒結段102中傳送通道的出口連通,並且降溫延滯段103的傳送通道203的出口與冷卻段104中傳送通道的入口連通,以使得從燒結段102離開的光伏裝置能夠進入降溫延滯段103的傳送通道203,並且從降溫延滯段103離開的光伏裝置能夠進入冷卻段104。此外,傳送通道203中還設有傳送帶(未示出),用於承載和傳送光伏裝置。FIG. 2A is a perspective view of the

從整體上說,如圖3A和3C所示,上爐膛201包括殼體、襯墊和加熱部件。襯墊設置在殼體內。具體來說,殼體包括上殼體301、左殼體302、右殼體303、後殼體304和前殼體305。左殼體302、右殼體303、後殼體304和前殼體305分別從上殼體301的左邊緣、右邊緣、後邊緣和前邊緣分別向下延伸形成。上殼體301、左殼體302、右殼體303、後殼體304和前殼體305圍合形成容腔,用於容納襯墊和加熱部件。在本案的實施例中,襯墊由岩棉製成。岩棉具有良好的保溫性能,以使得加熱部件產生的熱量保留在殼體圍合成的容腔中。As a whole, as shown in Figures 3A and 3C, the
上爐膛201中的襯墊包括上襯墊311、左襯墊312、右襯墊313、後襯墊314、前襯墊315、間隔襯墊317以及隔離襯墊316。上襯墊311、左襯墊312、右襯墊313、後襯墊314和前襯墊315分別設置在容腔的內壁上。換句話說,上襯墊311緊貼上殼體301,左襯墊312緊貼左殼體302,左襯墊312緊貼左殼體302,右襯墊313緊貼右殼體303,後襯墊314緊貼後殼體304,並且前襯墊315緊貼前殼體305。間隔襯墊317橫置在容腔中,並且大致與上襯墊311平行設置。間隔襯墊317與上襯墊311相距一段距離佈置,以使得上襯墊311、左襯墊312、右襯墊313、後襯墊314、前襯墊315和間隔襯墊317圍合形成間隔容腔321,並且使得左襯墊312、右襯墊313、後襯墊314、前襯墊315和間隔襯墊317圍合形成下方具有開口的加熱部件容腔322。加熱部件設置在加熱部件容腔322中。隔離襯墊316豎向設置在殼體中,以將間隔容腔321和加熱部件容腔322都隔開成為兩個獨立的間隔容腔321和兩個獨立的加熱部件容腔322。兩個獨立的間隔容腔321和兩個獨立的加熱部件容腔322對應於兩個傳送通道203佈置。The liners in the

下爐膛202還包括兩個氣體引入通道381,用於使殼體的外部的氣體(例如,空氣)能夠通過氣體引入通道381進入間隔容腔371。其中一個氣體引入通道381貫穿左殼體352和左襯墊362,另一個氣體引入通道381貫穿右殼體353和右襯墊363。當降溫延滯段103運行時,加熱部件產生熱量。兩個氣體引入通道381將外部的氣體引入間隔容腔371中。由於間隔襯墊367由岩棉製成,並且岩棉具有孔洞,因此氣體能夠穿過間隔襯墊367,在由殼體圍合形成更的容腔中流動。氣體的流動能夠使得加熱部件產生的熱量在殼體的容腔中更加均勻,從而有利於均勻加熱光伏裝置。The
如圖3B所示下爐膛202中的進一步細節,下爐膛202中的加熱部件包括八根加熱管391,用於產生熱量。具體來說,八根加熱管391分為兩組,每組包括四根加熱管391。兩組加熱管391分別設置在相應的加熱部件容腔372中。加熱管391的長度方向橫向於傳送帶的輸送方向佈置。當光伏裝置由傳送帶運輸時,一個光伏裝置會依次經過四根加熱管391。從而使得光伏裝置的溫度升高。加熱部件的加熱溫度是可調節的。作為一個示例,操作者可以調節流過加熱管391的電流的大小,從而調節加熱部件的加熱溫度。As shown in further detail in the
此外,下爐膛202還包括八塊石英板392和四根傳送帶支撐件393。具體來說,八塊石英板392中的每一塊佈置在八根加熱管391中相應的一個的上方,用於保護加熱管391,以防止傳送帶上掉落異物損壞加熱管391。四根傳送帶支撐件393分為兩組,每組包括兩根傳送帶支撐件393。兩組傳送帶支撐件393分別設置在相應的加熱部件容腔372中。傳送帶支撐件393佈置在石英板392的上方,並且兩端抵靠在殼體或襯墊上,或者與殼體或襯墊相連接。傳送帶支撐件393的長度方向沿傳送帶的輸送方向佈置,並且每組的兩根傳送帶支撐件393之間的間距小於傳送帶的寬度,以支撐傳送帶。In addition, the
由此,降溫延滯段103中的上爐膛201和下爐膛202形成一個完整的爐膛。該爐膛能夠將低於燒結段燒結溫度和燒結段預設溫度的降溫延滯段加熱溫度從上方和下方施加至進入該爐膛的光伏裝置上,然後將已經降溫的光伏裝置輸出降溫延滯段103,隨後將其輸送到冷卻段104中。上爐膛201中的後殼體304和前殼體305以及下爐膛202中的後殼體354和前殼體355在輸送方向的兩端形成分隔板,以使得降溫延滯段103的上爐膛201和下爐膛202與燒結段102以及冷卻段104隔開,從而避免熱量的散失。Thus, the
需要說明的是,雖然本案中燒結設備圖示具體數量的傳送通道、加熱管、石英板、傳送帶支撐件等,但本領域的技藝人士可以理解,任意數量的傳送通道和加熱管等均落在本案的保護範圍中。It should be noted that although the sintering equipment in this case shows a specific number of conveying channels, heating tubes, quartz plates, conveyor belt supports, etc., those skilled in the art can understand that any number of conveying channels and heating tubes, etc. within the scope of protection in this case.

圖4是現有技術燒結設備中的光伏裝置的距離-溫度關係示意圖。其中橫座標示出光伏裝置在燒結設備中沿燒結設備的長度方向移動的距離,縱座標表示光伏裝置的溫度,曲線表示現有技術燒結設備處理的光伏裝置在燒結設備中的溫度變化。圖4所示的燒結設備中不包括降溫延滯段。也就是說,圖4所示的燒結設備包括依次設置的烘乾段、燒結段和冷卻段。當光伏裝置離開燒結段時,光伏裝置會被加熱至燒結段預設溫度。隨後光伏裝置進入冷卻段,並在冷卻段中快速冷卻至冷卻段預設溫度。使用現有的燒結設備生產出的光伏裝置雖然在現有的要求和絕大多數情況下能夠滿足使用的需要,但是會出現光伏裝置成品的性能或性能參數不夠優良的情況,例如光伏裝置將太陽能轉化為電能的太陽能轉化效率和光伏裝置在使用中的衰減率不夠理想。FIG. 4 is a schematic diagram of the distance-temperature relationship of a photovoltaic device in a prior art sintering apparatus. The abscissa represents the distance that the photovoltaic device moves along the length of the sintering device, the ordinate represents the temperature of the photovoltaic device, and the curve represents the temperature change of the photovoltaic device processed by the prior art sintering device in the sintering device. The sintering equipment shown in Figure 4 does not include a cooling delay section. That is to say, the sintering equipment shown in FIG. 4 includes a drying section, a sintering section and a cooling section which are arranged in sequence. When the photovoltaic device leaves the sintering section, the photovoltaic device will be heated to the preset temperature of the sintering section. Then the photovoltaic device enters the cooling section, and is rapidly cooled in the cooling section to the preset temperature of the cooling section. Although the photovoltaic devices produced by the existing sintering equipment can meet the needs of use under the existing requirements and in most cases, the performance or performance parameters of the finished photovoltaic device may not be good enough. For example, the photovoltaic device converts solar energy into The solar energy conversion efficiency of electrical energy and the decay rate of photovoltaic devices in use are not ideal.
申請人經過觀察發現,在現有技術設備中,光伏裝置從燒結段輸出時的燒結段預設溫度與冷卻段冷卻溫度之間不恰當的初始降溫溫差會影響到光伏裝置的使用性能。具體地說,申請人經過觀察發現,當光伏裝置從燒結段輸出時,光伏裝置的溫度(即燒結段預設溫度)較高(例如為700-800℃),這會使得光伏裝置的溫度與冷卻段冷卻溫度(例如為40-80℃)之間的溫差太大,光伏裝置會在剛進入冷卻段時過快地降溫,而此時的過快降溫會造成在使用中的光伏裝置的太陽能轉化效率降低,即,在使用中,當光伏裝置將接收到的光能轉化為電能時,其太陽能轉化效率降低。相應地,在使用中,該光伏裝置隨著使用時間的衰減性能較高,使用壽命較短。The applicant has found through observation that, in the prior art equipment, the inappropriate initial cooling temperature difference between the preset temperature of the sintering section and the cooling temperature of the cooling section when the photovoltaic device is output from the sintering section will affect the performance of the photovoltaic device. Specifically, the applicant found through observation that when the photovoltaic device is output from the sintering section, the temperature of the photovoltaic device (ie, the preset temperature of the sintering section) is relatively high (for example, 700-800°C), which will make the temperature of the photovoltaic device and the cooling effect. If the temperature difference between the cooling temperatures (for example, 40-80°C) is too large, the photovoltaic device will cool down too quickly when it first enters the cooling stage, and the rapid cooling at this time will cause the solar energy conversion of the photovoltaic device in use. Reduced efficiency, ie, when a photovoltaic device converts received light energy into electrical energy, in use, its solar energy conversion efficiency decreases. Correspondingly, in use, the photovoltaic device has a high attenuation performance over time and a short service life.

圖5所示的燒結設備100包括降溫延滯段103。具體來說,燒結設備100包括依次設置的烘乾段101、燒結段102、降溫延滯段103和冷卻段104。在圖5所示的燒結設備100的實施例中,燒結段102為多段式設備。燒結段102提供的燒結段燒結溫度為多段式溫度。具體來說,燒結段102包括三個燒結單元(即,第一燒結單元、第二燒結單元和第三燒結單元)。每個燒結單元中包括一個燒結段加熱部件。第一燒結單元包括第一燒結段加熱部件501,其提供第一燒結段燒結溫度。第二燒結單元包括第二燒結段加熱部件502,其提供第二燒結段燒結溫度。第三燒結單元包括第三燒結段加熱部件503,其提供第三燒結段燒結溫度。其中第一燒結段燒結溫度低於或等於第二燒結段燒結溫度,並且第二燒結段燒結溫度低於或等於第三燒結段燒結溫度,以使得燒結段102連續使光伏裝置升溫以持續對光伏裝置進行加熱燒結。燒結段102被配置為使得光伏裝置離開燒結段102時,光伏裝置的溫度為燒結段預設溫度。在圖5所示的燒結設備100中,降溫延滯段103包括一個降溫延滯單元,其提供一個降溫延滯段加熱溫度。降溫延滯段103被配置為將低於燒結段預設溫度的降溫延滯段加熱溫度施加至光伏裝置,以使得光伏裝置以較為緩慢或被延滯的速度進行降溫。降溫延滯段103還被配置使得光伏裝置離開降溫延滯段103時,光伏裝置的溫度達到預期的降溫延滯段預設溫度。The
在圖5所示的燒結設備100的實施例中,冷卻段104為多段式設備。冷卻段104提供的冷卻段冷卻溫度為多段式溫度。具體來說,冷卻段104包括三個冷卻單元(即,第一冷卻單元、第二冷卻單元和第三冷卻單元)。每個冷卻單元能夠提供一個冷卻溫度。具體來說,第一冷卻單元能夠提供第一冷卻單元冷卻溫度。第二冷卻單元能夠提供第二冷卻單元冷卻溫度。第三冷卻單元能夠提供第三冷卻單元冷卻溫度。其中第一冷卻單元冷卻溫度高於或等於第二冷卻單元冷卻溫度,第二冷卻單元冷卻溫度高於或等於第三冷卻單元冷卻溫度,以使得冷卻段104持續對光伏裝置進行冷卻。冷卻段104被配置為使得光伏裝置離開冷卻段104時,將光伏裝置的溫度降溫至冷卻段預設溫度。其中冷卻段預設溫度低於降溫延滯段預設溫度。並且,每個冷卻單元的冷卻溫度都低於降溫延滯段加熱溫度。在圖5所示的燒結設備100的實施例中,每個冷卻單元提供的冷卻溫度相等,都大致等於燒結設備100所處的環境的溫度。進一步地,在圖5所示的燒結設備100的實施例中,每個冷卻單元中設有風扇511,512,513,以加速光伏裝置在冷卻段104中的散熱。In the embodiment of the
燒結段預設溫度、降溫延滯段預設溫度和冷卻段預設溫度均由待加工的光伏裝置決定。例如,根據待加工的光伏裝置的用途和種類進行決定。如前述,申請人發現從燒結段輸出的處於較高溫度的光伏裝置如果降溫速度過快,會造成在使用中的光伏裝置的太陽能轉化效率降低。本案發現,將光伏裝置從燒結段出來後的高溫段的降溫速度減緩,能夠提高使用中的光伏裝置的太陽能轉化效率。對於不同的光伏裝置,從燒結段出來後的高溫段的具體數值也會不同,因而不同的光伏裝置的降溫延滯段預設溫度也會不同。大體來說,降溫延滯段預設溫度高於燒結段預設溫度與冷卻段預設溫度的平均溫度。在一些實施例中,降溫延滯段預設溫度高於燒結段預設溫度的80%。The preset temperature of the sintering section, the preset temperature of the cooling delay section and the preset temperature of the cooling section are all determined by the photovoltaic device to be processed. For example, the decision is made according to the use and kind of photovoltaic device to be processed. As mentioned above, the applicant found that if the photovoltaic device at a higher temperature output from the sintering section is cooled too fast, the solar energy conversion efficiency of the photovoltaic device in use will decrease. It is found in this case that slowing down the cooling rate of the photovoltaic device in the high temperature section after the sintering section can improve the solar energy conversion efficiency of the photovoltaic device in use. For different photovoltaic devices, the specific values of the high temperature section after coming out of the sintering section will also be different, so the preset temperature of the cooling delay section of different photovoltaic devices will also be different. Generally speaking, the preset temperature of the cooling lag section is higher than the average temperature of the preset temperature of the sintering section and the preset temperature of the cooling section. In some embodiments, the preset temperature of the cooling lag section is higher than 80% of the preset temperature of the sintering section.
降溫延滯段加熱溫度設置為高於或等於降溫延滯段預設溫度。雖然降溫延滯段103中的降溫延滯段加熱部件113被設定為以降溫延滯段加熱溫度加熱,但由於上爐膛201和下爐膛202形成一個完整的爐膛,爐膛具有一定散熱量,這使得爐膛內的環境溫度低於降溫延滯段加熱溫度,因此當光伏裝置離開降溫延滯段103時,只能被保持在低於或等於降溫延滯段加熱溫度的降溫延滯段預設溫度。The heating temperature of the cooling delay section is set to be higher than or equal to the preset temperature of the cooling delay section. Although the cooling delay
在降溫延滯段預設溫度決定以後,降溫延滯段加熱溫度和降溫延滯段103沿著輸送方向的降溫延滯段長度根據待加工的光伏裝置、光伏裝置通過降溫延滯段103的速度等決定。降溫延滯段長度的設置要滿足光伏裝置在降溫延滯段中具有足夠的時間來產生降溫效果,同時又不影響光伏裝置的整體加工效率。在一些實施例中,降溫延滯段的長度為一個燒結單元長度的30%-70%。在降溫延滯段長度決定好之後,降溫延滯段預設溫度即可根據降溫延滯段長度和降溫延滯段預設溫度決定,使得光伏裝置在輸送通過延滯段長度之後溫度降低到降溫延滯段預設溫度。After the preset temperature of the cooling delay section is determined, the heating temperature of the cooling delay section and the length of the cooling delay section along the conveying direction of the
溫度降低速度是指光伏裝置通過一段長度L時其溫度的降低值T與長度L的比值。參考圖5中示出的燒結設備100,其中光伏裝置在降溫延滯段103中的溫度降低速度為T1/L1,光伏裝置在第一冷卻單元中的溫度降低速度為T2/L2。如圖5中的虛線所示,如果像圖4那樣沒有設置降溫延滯段103,光伏裝置從燒結段102輸出後直接進入冷卻段104,那麼光伏裝置在從燒結段102出來後的輸送長度L1這一段中的降溫速度將大於光伏裝置在降溫延滯段103中的溫度降低速度T1/L1,因為光伏裝置從燒結段102出來時的燒結段預設溫度與冷卻段104提供的冷卻溫度之間的溫差要比光伏裝置從燒結段102出來時的燒結段預設溫度與降溫延滯段103提供的降溫延滯段加熱溫度之間的溫差大。The temperature reduction rate refers to the ratio of the temperature reduction value T to the length L when the photovoltaic device passes through a length L. Referring to the
進一步地,在圖5所示的實施例中,降溫延滯段103和冷卻段104被配置為光伏裝置在降溫延滯段103中的溫度降低速度小於光伏裝置在距離降溫延滯段103最近的冷卻單元(在本實施例中為第一冷卻單元)中的溫度降低速度。也就是說,T1/L1<T2/L2。進一步地,降溫延滯段103被設置為使得光伏裝置在降溫延滯段103中的在前的溫度降低速度小於在後的溫度降低速度。降溫延滯段103可以避免光伏裝置在從燒結段輸出之後的高溫段的溫度過快下降,從而對從燒結段102離開的光伏裝置起到保溫作用。在光伏裝置從燒結段102輸出以後,延長已經經過燒結處理後的光伏裝置處於較高溫度的時間有利於增加生產出的光伏裝置在使用中的太陽能轉化效率、降低該光伏裝置的衰減性能、延長其使用壽命。作為一個示例,對於同一種用途和種類的光伏裝置來說,相比於在加工程序中未經由降溫延滯段103的光伏裝置,在加工程序中經由降溫延滯段103的光伏裝置的太陽能轉化效率能夠增加5%-10%,並且其使用壽命能夠延長1%-2%。Further, in the embodiment shown in FIG. 5 , the
作為一個示例,在操作中,對於某種種類和用途的光伏裝置來說,燒結段燒結溫度(例如,第三燒結段燒結溫度)為800℃,燒結段預設溫度為780℃,降溫延滯段加熱溫度為750℃,降溫延滯段預設溫度為720℃,冷卻段預設溫度(例如,第四冷卻單元冷卻溫度)為60℃。也就是說,降溫延滯段103能夠將光伏裝置的溫度從780℃降低為720℃,隨後冷卻段104將光伏裝置的溫度從720℃降低為60℃。As an example, in operation, for a certain type and application of photovoltaic devices, the sintering temperature of the sintering section (eg, the sintering temperature of the third sintering section) is 800°C, the preset temperature of the sintering section is 780°C, and the cooling delay is The heating temperature of the section is 750°C, the preset temperature of the cooling delay section is 720°C, and the preset temperature of the cooling section (for example, the cooling temperature of the fourth cooling unit) is 60°C. That is, the
作為另一個示例,對於某種種類的光伏裝置來說,烘乾段預設溫度為300℃-400℃,燒結段預設溫度為700℃-900℃,降溫延滯段加熱溫度為650℃-750℃,冷卻段預設溫度為40℃-80℃。降溫延滯段長度為600mm,光伏裝置通過降溫延滯段103的速度為11000mm/分鐘。As another example, for a certain type of photovoltaic device, the preset temperature of the drying section is 300℃-400℃, the preset temperature of the sintering section is 700℃-900℃, and the heating temperature of the cooling delay section is 650℃- 750℃, the preset temperature of the cooling section is 40℃-80℃. The length of the cooling delay section is 600 mm, and the speed of the photovoltaic device passing through the
本案將光伏裝置從燒結段102輸出時的燒結段預設溫度與冷卻段104的輸入端所施加溫度(即,第一冷卻單元冷卻溫度)之間的溫差分成兩個相對小的、合適的降溫溫差,並用降溫延滯段103和冷卻段104在不同的兩個時間段內分別對光伏裝置進行降溫。因為光伏裝置從燒結段102輸出時達到較高的燒結段預設溫度,所以降溫延滯段103要設置合適的降溫延滯段加熱溫度,使從燒結段102輸出的光伏裝置的燒結段預設溫度與降溫延滯段103的降溫延滯段加熱溫度的降溫溫差處於合適的範圍,從而控制光伏裝置在從燒結段102輸出後的第一段降溫速度。在降溫延滯段103中,光伏裝置以合適的降溫速度降溫,使得光伏裝置在降溫延滯段103中以合適的降溫速度降到中間狀態溫度(即,降溫延滯段預設溫度),光伏裝置從降溫延滯段103輸出時達到中間狀態溫度(即,降溫延滯段預設溫度)。降溫延滯段103通過合適地選擇施加的降溫延滯段加熱溫度,減小從燒結段102輸出的光伏裝置溫度與降溫延滯段103所提供的降溫延滯段加熱溫度之間的溫差,從而減小光伏裝置在從燒結段102輸出後處於較高溫度時的降溫速度。而在冷卻段104中,由於降溫延滯段103已經將光伏裝置的溫度以合適的降溫速度降低,光伏裝置以降低的溫度進入冷卻段104,使得光伏裝置的溫度與冷卻段104所提供的冷卻溫度之前的溫差也降低,從而使得光伏裝置在冷卻段104中也以合適的降溫速度降溫,降到冷卻段預設溫度。In this case, the temperature difference between the preset temperature of the sintering section when the photovoltaic device is output from the
在本案中,通過設置降溫延滯段103和冷卻段104兩個對從燒結段102輸出的光伏裝置進行冷卻處理的段,將現有技術燒結設備中光伏裝置的一個降溫溫差分割成兩個合適的、較小的降溫溫差,以控制光伏裝置從燒結段預設溫度降低到冷卻段預設溫度的合適降溫速度,尤其是控制光伏裝置剛從燒結段輸出時處於較高溫度時的合適降溫速度,從而達到提高使用時光伏裝置的太陽能轉化效率和降低該光伏裝置的衰減性能。In this case, by setting the
還需要說明的是,雖然本案中燒結段102包括三個燒結單元,並且冷卻段104包括四個冷卻單元,但本領域的技藝人士可以理解,包括至少兩個燒結單元的燒結段102以及包括至少兩個冷卻單元的冷卻段104都在本案的保護範圍內。It should also be noted that although the
