Abstract
A portable moisture trap for use with a vacuum pump includes: a housing; a cooling chamber positioned at least partially within the housing including a first inlet port and a second outlet port; a lid that sealably attaches to a top portion of the cooling chamber to seal the cooling chamber; a heat sink residing under the cooling chamber; a thermoelectric device having an upper cooling side and a lower heat generating side residing between the cooling chamber and the heat sink; a fan oriented to blow air upwardly toward the heat sink; and a baffle extending downwardly in the cooling chamber from a location proximate the lid to a location proximate an inner bottom surface of the cooling chamber, with the baffle configured to define a physical barrier to urge air received through the first port to flow down toward the inner bottom surface of the cooling chamber before exiting through the second port, to thereby remove moisture from air traveling through the cooling chamber in response to a vacuum pump in fluid communication with the second port.
