Abstract
A portable cooling unit comprising a magnetic spiral vapor pump that utilizes a magnetic pulse between two electromagnets and spiral drive slots to pull a piston back-and-forth 180-degrees and thereby alternately align compression slots on the piston's opposing ends with vapor suction ports and highly-compressed vapor discharge ports. Electromagnet use lowers the amount of battery power required for piston rotation. A condenser in a mounting pan under the pump achieves refrigerant condensation, while a fan blowing air through an evaporator positioned within a flexible hose causes cool air discharge through openings in the hose's terminal end fitting. The condenser utilizes surplus condensation from the evaporator to aid its vapor-to-liquid conversion, and batteries only provide power for the magnetic control module and fan. Applications include, but are not limited to, medical applications and the cooling of small spaces, such as those surrounding children's strollers, play pens, wheel chairs, and pet carriers.
