Abstract

A technique to cool air to decrease dew point includes using a thermoelectric cooler. The cooler includes a cold side where heat is absorbed and a hot side where heat is rejected into a heat sink. The cooler includes ceramic substrates, followed by copper conductors at both cold and hot sides of the cooler assembly. Further, p and n semiconductor plates are sandwiched between the ceramic substrates and copper conductors.

APPARATUS TO DEHUMIDIFY AIR FLOW

BRIEF ABSTRACT

A technique to cool air to decrease dew point includes using a thermoelectric cooler. The cooler includes a cold side where heat is absorbed and a hot side where heat is rejected into a heat sink. The cooler includes ceramic substrates, followed by copper conductors at both cold and hot sides of the cooler assembly. Further, p and n semiconductor plates are sandwiched between the ceramic substrates and copper conductors.

DETAILED DESCRIPTION

Generally, air probes, such as, hydrogen (H2) probes or oxygen (O2) probes require air testing within a certain relative humidity (RH) range.  However, some probes are damaged if a probe reaches dew point. Therefore, it is required to decrease RH of air.

A conventional technique includes a vortex cooling system for cooling air. The vortex cooler separates compressed air into cold and hot currents. However, the quantity of air released from hot exhaust is required to be adjusted to control temperature quantity of cold air and temperature. For example, increasing hot air flow reduces cold venting.

Hence there exists a need for a technique to cool air to decrease dew point.

Disclosed herein is a technique to cool air to decrease dew point. The technique includes a thermoelectric cooler to cool air. FIGURE 1 depicts a schematic of the thermoelectric cooler. The cooler includes a cold side where heat is absorbed and a hot side where heat is rejected into heat sink. The cooler includes ceramic substrates, followed by copper conductors at both cold and hot side of...
