Abstract: There is provided a tube coupling configured to connect and couple two tubes that are configured to cause a fluid to flow inside the two tubes. The tube coupling includes: a male connector including an insertion part having a protruding shape protruding in an axial direction that is an insertion direction; and a female connector including an insertion receiving part having a recessed shape recessed in the axial direction and coupled to the insertion part when the insertion part is inserted into the insertion receiving part. The insertion part includes a projection disposed on a side surface of the male connector. The insertion receiving part includes a first through hole on a side surface of the female connector. The first through hole extends in a direction inclined with respect to the axial direction, and is configured to allow the projection to move in the first through hole.

Abstract: A cooling device includes a base material providing a heating element on a first surface and a heat exchanger on a second surface opposite to the first surface, the heat exchanger receiving heat from the heating element to perform heat exchange with a refrigerant, and a case material including a refrigerant inflow port and a refrigerant outflow port, the refrigerant inflow port supplying the refrigerant to the heat exchanger. The case material is attachable to the base material in two forms of a first form and a second form, the first form being a form in which the refrigerant inflow port and the refrigerant outflow port are attached to the base material in a first direction, and the second form being a form in which the refrigerant inflow port and the refrigerant outflow port are attached to the base material in a second direction different from the first direction.

Abstract: A cooling device of a projection display apparatus includes a first heat receiving unit including an opening that is rectangular. The first heat receiving unit includes a flow path part that forms the opening. An image display element of the projection display apparatus includes a first front face located in front of a reflective image display, a second front face parallel to the first front face and located behind and outside the first front face, and a first side face located between the first front face and the second front face. The first front face is inserted into the opening, and the flow path part is in contact with the first side face and the second front face via a heat conductive member. The flow path part includes a front face that is flush with or in front of the first front face of the image display element.

Abstract: A heat exchanger includes a plurality of heat exchange tubes stacked with a gap through which a first fluid can pass. The heat exchange tube includes: an internal flow path through which a second fluid for exchanging heat with the first fluid and which includes a folded portion; a plurality of slits provided between two flow path portions in the internal flow paths, the two flow path portions each extending from the folded portion and facing each other at an interval; and a plurality of protruding support portions in contact with another adjacent heat exchange tube to form the gap. As viewed in a stacking direction of the plurality of heat exchange tubes, at least one of the plurality of slits extends in a state where a center in an extending direction thereof deviates from a straight line connecting the two adjacent protruding support portions.
