1. A heat exchanger configured to conduct refrigerant through the heat exchanger, comprising:
a side plate portion, wherein a thickness direction of the side plate portion serves as a stacking direction that is predetermined;
a heat releasing unit that includes a plurality of heat releasing constituents which are joined together, wherein:
a plurality of heat releasing flow passages are formed in the plurality of heat releasing constituents, respectively; and
the heat releasing unit is configured to release heat from the refrigerant flowing in the plurality of heat releasing flow passages by exchanging the heat between the refrigerant flowing in the plurality of heat releasing flow passages and air; and
an evaporating unit that includes a plurality of evaporating constituents which are joined together, wherein:
a plurality of evaporating flow passages are formed in the plurality of evaporating constituents, respectively;
the evaporating unit and the heat releasing unit are arranged one after another in a direction along the side plate portion;
the evaporating unit is configured to evaporate the refrigerant by let the refrigerant flowing in the plurality of evaporating flow passages absorb heat by exchanging the heat between the refrigerant flowing in the plurality of evaporating flow passages and the air;
the plurality of heat releasing constituents are stacked in the stacking direction;
the plurality of evaporating constituents are stacked in the stacking direction;
the heat releasing unit and the evaporating unit are both fixed to the side plate portion;
a heat releasing unit outlet is formed at an outlet-side heat releasing constituent that is one of the plurality of heat releasing constituents placed at an end of the plurality of heat releasing constituents;
an evaporating unit inlet is formed at an inlet-side evaporating constituent that is one of the plurality of evaporating constituents placed at an end of the plurality of evaporating constituents;
all of the plurality of heat releasing flow passages, which are respectively formed in the plurality of heat releasing constituents, are connected to the plurality of evaporating flow passages through the heat releasing unit outlet and the evaporating unit inlet;
the stacking direction is a direction that intersects a gravity direction; and
the heat releasing unit is located on a lower side of the evaporating unit.
