<p>A water bottle fridge consist of a bottle and a cooling unit. the cooling unit consist of a bottle cap,a nozzle,an evaporator, an inlet valve, a plastic frame and a rim. A nozzle is used to let the water inside the bottle to flow out. This nozzle is attached to the bottle cap to it's appropriate hole. An inlet valve is first fasterned to the inlet of the evaporator and then this inlet valve is attached to the bottle cap to it's appropriate hole. The outlet of the evaporator is attached to it's appropriate hole in the bottle cap. A plastic frame is inserted between the center of the evaporator and is glues to the bottle cap, it is only used to support the evaporator, since copper deforms even in very lite stress, A small bend in the shape of evaporator will block the gases flowing through the evaporator, which might lead to faliure in working of the evaporator. A plastic rim with the thread designed on the interior side of rim is glued to bottle cap. when this bottle cap is screwed to the bottle consisting of water and gases or air in compressed form is passed through the inlet of evaporator, it starts cooling the evaporator and there by the evaporator cools the water inside the bottle in it.</p> |
