Abstract
A cooling vest module includes a flexible back plate attachable to a garment and at least one thermoelectric cooler mounted thereon. An annular gasket on an inner surface of the back plate seals against a wearer's back to define a confined recirculation space. Each cooler draws ambient air through an external inlet, discharges cooled air into the recirculation space via a cold-air outlet, and exhausts waste heat through heat-dissipation apertures. A recirculation inlet returns part of the cooled air for further cooling, while mounting features, support pads, and optional twin coolers ensure secure installation and structural integrity. The module provides efficient, true recirculating cooling and is particularly suitable for safety vests worn by environmental sanitation workers.

A cooling vest module, comprising:
- a flexible back plate configured for connection to a garment and having an inner surface;
- and
- at least one cooler mounted on the flexible back plate and configured to generate cool air,
- wherein an annular gasket is molded on an inner surface of the flexible back plate so as to define, together with the inner surface, a channel;
- wherein, when the flexible back plate is placed against a wearer's back, the gasket contacts the wearer's back to form a sealed space between the channel and the wearer's back;
- wherein the cooler includes heat-dissipation apertures and an external air inlet communicating with an external environment, and further includes a cold-air outlet and a recirculation air inlet positioned on a side of the cooler that faces the sealed space, the cold-air outlet and the recirculation air inlet opening into the channel.
