摘要: A contact welding detection system includes a main circuit including a DC power source, a power-supply unit electrically connected to the DC power source, and a main circuit relay electrically connected between the DC power source and the power-supply unit, a measurement unit measuring an electrical characteristic value on a signal wiring between a signal generation unit and the main circuit. The system further includes a welding determination unit configured to determine the presence or absence of contact welding in the relay on the basis of the electrical characteristic value, and a first forced ground-contacting unit electrically connected between the main circuit and a conductive member connected to ground. The first forced ground-contacting unit is electrically connected to the main circuit at a connection point located on an opposite side of the relay to a connection point at which the signal generation unit is electrically connected to the main circuit.

摘要: A blower configured to suction and discharge first fluid and second fluid includes a fan and a division wall. The fan is configured to rotate relative to the division wall. The division wall is spaced from the fan and positioned in a suction space, the division wall partitioning the suction space into a space through which the first fluid passes and a space through which the second fluid passes. The division wall includes a base and a widened portion. The base guides flows of the first fluid and the second fluid toward the fan. In the suction space, the widened portion is closer to a rotation area of the fan than the base is. A width of the widened portion in a direction along a thickness of an end of the base connected to the widened portion is larger than the thickness of the end of the base.

摘要: A humidification device includes: an adsorber having an adsorbent that adsorbs and desorbs moisture; an adsorption case that forms an accommodating space to accommodate the adsorber; a first introduction portion that introduces cooled air produced by a cooling portion into the adsorption case; a second introduction portion that introduces heated air produced by the heating portion into the adsorption case; and a humidification-side guiding portion that guides humidification air humidified by the moisture desorbed within the adsorption case, to the vehicle interior. The first introduction portion is connected to a bottom surface portion of the air-conditioning case on the air-flow downstream side of the cooling portion in the air-conditioning case.

摘要: Multiple projections are provided at a flow-change portion, which corresponds to such a portion of a wall surface of an A/C casing, at which velocity gradient of air current becomes larger in an area adjacent to the wall surface, in order to decrease aerodynamic sound generated by disturbed air current.

摘要: An air blowing device of the present disclosure has a wall portion, a duct, a guide wall, and an airflow forming mechanism. The wall portion is provided with an opening periphery providing a blow outlet. The duct communicates with the blow outlet. The guide wall is provided in an inner wall of a downstream portion of the duct and has a wall surface having a shape protruding toward an inside of the duct. The airflow forming mechanism forms a flow of air along the guide wall such that the air flowing through the duct is blown out of the blow outlet while being bent along the guide wall. The opening periphery has a portion that communicates with a downstream side of the guide wall and that has a shape protruding in a blowing direction of the air, which is bent along the guide wall from the blow outlet.

摘要: An air conditioner for a vehicle includes a casing that forms an air passage through which air flows, a blower fan to blow out air, and a heating device to heat air. The casing includes a passage portion through which air flows, a warm air passage that allows air to flow to the heating device, and a bypass passage that allows air to bypass the heating device. A width dimension of the passage portion in a second direction is larger than that of the heating device in the second direction, and is smaller than a height dimension of the passage portion in a first direction.

摘要: A vehicular air conditioning device includes an air conditioning case having first, second case introduction ports and first, second case discharge ports, and a fan. The first, second case discharge ports are offset upward and downward in an up-down direction relative to a rotation axis, respectively. A first inner guide surface of an inner guide plate is located on the one side of a second inner guide surface in the left-right direction. Air introduced through the first case introduction port is guided by the first inner guide surface to be drawn from a first passage into the fan, the air being blown upward to flow through the first case discharge port. Air introduced through the second case introduction port is guided by the second inner guide surface to be drawn from a second passage into the fan, the air being blown upward to flow through the second case discharge port.

摘要: In a vehicular air conditioning unit, an air conditioning case includes a space forming portion that forms a drainage space which is partitioned from an air passage. The space forming portion includes a drainage portion that discharges water from inside the air conditioning case to outside of the air conditioning case. Further, the space forming portion includes an upstream side communication portion that communicates the drainage space to an upstream side space on an air flow upstream side of the blower in the air passage. Further, the space forming portion includes a downstream side communication portion that communicates the drainage space to a downstream side space on the air flow downstream side of the blower in the air passage.

摘要: An air-conditioning includes a blower, a unit casing, an upstream partition, and a fan partition. The blower includes a centrifugal fan and a fan casing. The unit casing defines an upstream passage at a position upstream of the blower. The upstream partition is fixed to the unit casing to divide the upstream passage into a first upstream passage through which a first gas flows and a second upstream passage through which a second gas flows. The fan partition is fixed to the fan casing to divide an inner space of the fan into a first fan passage through which the first gas flows and a second fan passage through which the second gas flows. The unit casing defines an opening and includes a cover that closes the opening. The opening has an opening area such that the blower is removable from the unit casing through the opening.
