Abstract: A refrigerant distributor includes: a first introduction pipe configured to be open at a first end and closed at a second end and to cause refrigerant to flow from the first end toward the second end; a second introduction pipe configured to be closed in ends on both upstream and downstream sides and to cause the refrigerant to flow in a direction opposite to a refrigerant flow direction in the first introduction pipe; a plurality of branch pipes connected in series along a refrigerant flow direction on the second introduction pipe; and an adjusting pipe configured to connect the first introduction pipe and the second introduction pipe.

Abstract: An electronic apparatus includes heat generating components accommodated in a sealed housing section of a housing, an internal-side heat exchanger and an external-side heat exchanger on opposing sides of a wall of the housing, an external-side heat exchanger for heat generating components for heat exchange between the heat generating components and air outside the housing section, and an internal fan. A high-heat generating component generating the most heat contacts the inner surface and opposed to the external-side heat exchanger for heat generating components. Heat exchange between the high-heat generating component and air outside the housing section is effected via the external-side heat exchanger for heat generating components. Heat exchange between air inside the housing section and air outside the housing section is effected via the internal-side heat exchanger and the external-side heat exchanger.
