This creation is about a kind of cooling device, which is mainly connected between two corresponding water storage devices with connecting pipes made of metal material. The connecting pipes are sleeved in the perforations of the sleeves, and the sleeves are locked by the locks. The assembling hole opened on the assembling end surface of the water storage device, the outer end of the sleeve is provided with a compression section, which is locked and fixed on the outer end of the sleeve with the compression member, and a compression section is formed on the inner edge of the compression member. The compression section is used to compress the compression section, so that the compression section will tightly pinch the connecting pipe that penetrates the perforation to prevent it from falling off； thereby, it can not only effectively cool down the environment, but also prevent it from falling off. The humidity increases, and the practical performance characteristics are increased in its overall implementation.本創作係有關於一種降溫器，其主要係於兩相對應設置之蓄水裝置間連接設有數金屬材質製作之連通管，連通管套設於套固件之穿孔內，套固件以鎖固件鎖固在蓄水裝置之組接端面所開設的組接孔，套固件外端設有壓迫段，利用迫緊件鎖設固定在套固件外端，於迫緊件內緣對應壓迫段形成有迫緊段，利用迫緊段對壓迫段進行迫緊，使得壓迫段將穿設於穿孔內之連通管予以緊掣壓迫定位不脫落；藉此，不僅能有效對環境內進行降溫，且能防止環境中的濕度增加，而在其整體施行使用上更增實用功效特性者。
