循環水冷卻器的原理是由三個過程共同作用的
點擊次數:2028 發布時間:2019-01-04
  循環水冷卻器主要用于溫度要求低于室溫的實驗,自帶制冷壓縮機和循環泵,是制冷加熱一體化產品,又稱低溫水浴槽。造形簡單緊湊,操作方便,可單機操作,在槽內進行低溫實驗。
 
  循環水冷卻器的原理是通過水與空氣接觸,由接觸散熱、蒸發散熱和輻射散熱三個過程共同作用的結果。
  1、接觸散熱:借傳導和對流傳熱,稱為接觸散熱。水面與較低溫度的空氣接觸,由于溫差使熱水中的熱量傳到空氣中去,水溫得到降低。溫差越大,傳熱效果越好。
  2、蒸發散熱:水在冷卻設備中形成大小水滴或極薄水膜,擴大其與空氣的接觸面積和延長接觸時間,加強水的蒸發,使水汽從水中帶走汽化所需的熱量,從而使水冷卻。
  3、輻射散熱:輻射散熱不需要傳熱介質的作用,而是由一種電磁波的形式來傳播熱能的現象。輻射散熱只是在大面積的冷卻池內才起作用。
 
  循環水冷卻器的作用是通過溫度相對較低的水來把儀器所產生的熱量帶走,從而使儀器部分的溫度保持在一個較低的水平。目前循環水冷卻器廣泛用于激光打標機、激光切割機、激光焊接、激光打孔等激光設備。由于自來水水壓不穩和水銹較多堵塞微細小管,影響機器的正常運轉;而水資源短缺的矛盾的日益突出,以及儀器設備對冷卻水的水質和溫度的要求越來越高,循環水冷卻器也就成為越來越多人的選擇。


循環水冷卻器

  循環水冷卻器產品特點:
  1、循環接嘴可以360度旋轉,方便進行各種系統連接。
  2、所有與載冷劑接觸部件全部采用不銹鋼以及高分子耐腐材料,可以保障長時間帶負荷工作。
  3、制冷壓縮機采用日本品牌產品,高可靠性,可以長時間工作。
  4、DL系列為風冷型,節省寶貴的水資源。
  5、制冷功率大,溫度范圍:-15℃至常溫, 溫度采用上,下限控制,操作簡單方便。
  6、設計合理,節省空間。
