11554640 · 2023-01-17 · ·

Technologies described herein are directed to isolating or insulating at least portions of an evaporator coil within a climate control unit (CCU) of a TCCS so as to reduce or even eliminate adverse effects caused by a leaked working fluid. Such adverse effects may include a threat of ignition, asphyxiation of occupants, damage to cargo, and other harmful effects caused by emission of a noxious gas. A leak isolation structure is provided to isolate evaporator tubes of an evaporator coil from at least one of a plurality of turns of the evaporator coil.

HEAT EXCHANGER FOR VEHICLES

A heat exchanger for vehicles includes a condenser configured such that coolant and refrigerant performs heat exchange while flowing in a state separated from each other and being formed by a stacking of a plurality of first heat exchange plates; a gas-liquid separator for separating gaseous components from the refrigerant that has passed through the condenser; a supercooler configured such that the coolant having passed the condenser and the coolant having passed the gas-liquid separator performs heat exchange while flowing in a separated state from each other and being formed by a stacking of a plurality of second heat exchange plates; and a connector that is interposed between the condenser and the supercooler and forms a coolant passage allowing the coolant to flow from the condenser to the supercooler and a refrigerant passage allowing the refrigerant to flow from the condenser to the supercooler via the gas-liquid separator.

DEVICE FOR REGULATING A THROUGHFLOW AND DISTRIBUTING A FLUID IN A FLUID CIRCUIT
