摘要： A evaporator for use in a refrigerating cycle in an air conditioning apparatus for a vehicle. The evaporator is provided with a heat exchanger and an evaporator. The heat exchanger has an inlet passageway for leading the refrigerant from the condenser to the evaporator, and an outlet passageway for leading the refrigerant from the evaporator to the compressor. A heat exchange between the inlet refrigerant and the outlet refrigerant at the heat exchanger part takes place, so that a combined gas-liquid state refrigerant is introduced into the outlet passageway of the heat exchanger from the evaporator, whereby a superheating state of the refrigerant is generated in the outlet passageway, and a result, no superheating action occurs in the evaporator, and thus the refrigerant in the evaporator is kept at a constant temperature, whereby the cooling efficiency of the evaporator is increased.

摘要： A refrigerant evaporator for a refrigeration cycle which separates a refrigerant of a two-phase gas and liquid state introduced from a pressure reduction means into a liquid refrigerant and a gas refrigerant by a gas and liquid separation means and distributes at least the liquid refrigerant to a plurality of refrigerant passageways of a heat exchange portion by a distribution means such as a tank. The distributed refrigerant has a single phase such as a liquid refrigerant and therefore the distribution is uniformly and equally carried out, the efficiency of the evaporator becomes higher, and the size can be reduced.

摘要： A pair of heat conductive plates forming an evaporator core portion has a plurality of projection ribs. The projection ribs protrude toward outsides of the pair of heat conductive plates for forming refrigerant passages thereinside. Air flows outside the heat conductive plate perpendicularly to a flow direction of the refrigerant, and is prevented from flowing straightly by the projection ribs to make a turbulent flow.

摘要： A heater for an air conditioner includes plural water tubes and plural refrigerant tubes which are arranged in parallel in an air flow direction. Therefore, the heater can heat air by using at least one of the heating sources while a pressure loss in the heater can be effectively reduced. For example, in a quick-heating mode, high-temperature refrigerant from a refrigerant cycle flows into the heater to heat the blown air, and low-temperature engine-cooling water from an engine bypasses the heater. In this case, thermal leakage from the refrigerant to the engine-cooling water is avoided.
