各位好,小弟這幾天買了一咖全鋁水箱,要拿去車廠請師傅換掉原廠型的水箱
師傅看到我的全鋁水箱,說我的水箱有點太厚了,散熱不一定會好,
說以散熱來說,是「面積越大越好,厚度越薄越好」,而我的全鋁水箱只有比較厚。
不過我是覺得沒那麼不堪...受風面積相同,水箱變厚散熱應該不至於倒退嚕吧?
我反而覺得,理論上散熱會比原本的好一些些,至少上下都變金屬材質,
金屬接觸空氣的面積變多了,水箱厚度變厚,帶走的熱量也會稍微多點。
想請問真的會有加厚水箱,結果散熱不好的問題嗎?
師傅提醒我三次這種不一定好,真的說了三次,要我三思,搞得我有點緊張QQ
故上來請教版友,謝謝各位
以下是兩個水箱的比較:
原廠水箱:單排水道,冷排目測25mm厚,上下塑鋼材質

全鋁水箱:雙排水道,冷排40mm厚,全鋁材質
