  • Patent number: 10549598
    Abstract: A vehicle air-conditioning apparatus includes a casing that defines an air passage through which an air flows, and a blower that has a blower fan generating an airflow in the air passage. The vehicle air-conditioning apparatus includes an air-conditioning device that is provided in the air passage, and an air introduction member that introduces an air from a vehicle compartment. The vehicle air-conditioning apparatus further includes an aspirator that is located outside the casing and takes in the air flowing through the air passage as a first air, the aspirator drawing the air from the vehicle compartment as a second air through the air introduction member by using a flow of the first air. A cooling target mounted in the vehicle is cooled by a flow of the air drawn from the vehicle compartment by the aspirator through the air introduction member.

  • Publication number: 20180298914
    Abstract: A blower includes a fan that rotates about an axis center in an air conditioning case, and a casing that guides air blown from the fan. The casing has a peripheral wall that is located radially outward of the fan with the axis center as a center. The peripheral wall has first and second scroll inner wall surfaces that guide different kinds of air blown from the fan to different outlets. No half-lines starting from the axis center passes through both of the first and second scroll inner wall surfaces.

  • Publication number: 20180099542
    Abstract: A cooling device is applied to an in-vehicle equipment having a cooling unit which cools air, and cools an in-vehicle heat-emitting apparatus with the air cooled by the cooling unit. The cooling device includes: an adsorption unit including an adsorption material which adsorbs moisture; an adsorption case that defines a housing space in which the adsorption unit is disposed, the air cooled by the cooling unit passing through the adsorption case, the adsorption material adsorbing moisture from the air; and a cooling air outlet part that guides a dehumidification air, from which the moisture is adsorbed within the adsorption case, to a target space to be cooled where the heat-emitting apparatus is arranged.

  • Patent number: 9937768
    Abstract: An air conditioning device for vehicle has guide plates that guide a flow of air on a downstream side of a heating heat exchanger. In order to form a first path, the guide plates have a first guide that extends from a downstream wall surface of the heating heat exchanger and bends in an upward direction. Further, in order to hold a heat exchanger other than a cooling heat exchanger and the heating heat exchanger, the guide plates have a second guide that extends from an upper end part of the heating heat exchanger and bends in a downward direction. Furthermore, the guide plates have a third guide that extends from the first guide toward an end of the second guide.

  • Publication number: 20180029447
    Abstract: A humidification device for a vehicle air conditioner includes an adsorber having an adsorbent, an adsorption case configured to provide an accommodating space that accommodates the adsorber and includes a moisture-adsorption space and a moisture-desorption space, a humidification-side guiding portion that guides humidification air humidified by using the moisture desorbed within the moisture-desorption space to a vehicle interior, a moving mechanism that moves at least a part of the adsorbent existing in the moisture-adsorption space of the adsorber to the moisture-desorption space while moving at least a part of the adsorbent existing in the moisture-desorption space of the adsorber to the moisture-adsorption space, and a desorption control unit that executes a desorption operation to desorb moisture adsorbed in the adsorbent when humidification of the vehicle interior is stopped.
