The present invention provides a piping unit that facilitates downsizing of a cooler by decreasing the temperature of fluid to be introduced into the cooler without reducing the cooling effect of a cooler. A piping unit is for introduction of heated fluid into a cooler, the piping unit being formed from synthetic resin and including a heat exchange structure on an inner peripheral surface.

An air conditioning system for motor vehicles includes an air conditioner case, an evaporator installed inside the air conditioner case, a drainage hose configured to discharge condensate water generated in the evaporator to the outside of a vehicle room, the drainage hose connected to a drainage port of the air conditioner case and drawn out to the outside of the vehicle room through a dashboard, and a connector part configured to rotatably connect the drainage hose to the drainage port of the air conditioner case.

Heat exchanger exchanging heat between coolant and refrigerant of different kinds in one device and providing an effective heat exchange ratio between the coolant and the refrigerant. The heat exchanger includes a refrigerant flow path having a refrigerant inlet and a refrigerant outlet, and a coolant flow path through which coolant flows to exchange heat with the refrigerant. The coolant flow path includes a first coolant flow path where first coolant flows, and a second coolant flow path where second coolant with a different kind flows. The heat exchanger is partitioned into a first heat exchange section, in which the first coolant exchanges heat with the refrigerant and a second heat exchange section, in which the second coolant exchanges heat with the refrigerant, so that the heat exchange in the first heat exchange section and the heat exchange in the second heat exchange are carried out independently.

Disclosed is a cooling system for an electrical control unit of a vehicle, the cooling system including a cooling element having a first flow channel for coolant and a second flow channel for coolant, a flow reverse element adapted to guide coolant from the first flow channel to the second flow channel, and a flow guiding element for guiding at least part of the coolant from the first flow channel to the second flow channel.

An ancillary system for a motor vehicle is provided. The system comprises a housing; a duct for carrying a fluid to or from the housing, wherein the duct comprises a duct portion and a connector portion connecting the duct to the housing, wherein the duct portion is spaced apart from the housing in a first direction; and a spacer, the spacer being coupled to one of the duct and the housing and arranged between the duct and the housing to reduce a dimension of a gap between the duct and the housing in the first direction, and thereby reduce a displacement of the duct in the first direction during a collision. A motor vehicle assembly comprising the air ancillary system is also provided.

A vehicle air conditioner includes an air-conditioning case having a drain hole through which an air passage communicates with an outside of a vehicle compartment, a heat exchanger disposed inside the air passage, and a seal member. The seal member is held between a dash panel and a seal wall of the air-conditioning case. The seal member has a through hole, and closes a through hole of the dash panel. The vehicle air conditioner includes a refrigerant pipe and a pressure reducing valve. The first case part and the second case part are fitted with each other in a fitting part below which, in the vertical direction, the air-conditioning case has a communication hole through which an outside of the air-conditioning case communicates with the air passage.

A seal assembly for an air conditioning system includes an annular inner seal member and an annular outer seal member coupled to the inner seal member. The outer seal member has a first recess formed in a first surface thereof. The first recess transitions between a substantially closed configuration when the outer seal member is compressed and a substantially open configuration when the outer seal member is decompressed.

A block fitting assembly comprises a first block having a first fastener aperture formed therethrough, a second block having a second fastener aperture formed therethrough in axial alignment with the first fastener aperture, and a fastener extending through the first fastener aperture and the second fastener aperture to couple the first block to the second block. The block fitting assembly includes a thermal expansion compliancy feature in the form of at least one of an inner surface of the second block defining the second fastener aperture including an axially extending non-threaded portion adjacent a threaded portion thereof or the fastener including a necked portion having a smaller outer diameter than a minor thread diameter of a threaded portion of the fastener.

Systems and methods are provided for thermal control using vascular channels. Vascular channels are incorporated in a network within a component. The component is a part of a manufactured environment configured for occupants. A fluid circuit is connected with the vascular channels and circulates a fluid through the component to alter a thermal state of the component.

The present invention is provided with: an evaporator (6) in which a compressed refrigerant is vaporized; an expansion valve expanding the refrigerant before the refrigerant flows into the evaporator (6); refrigerant pipes (26, 27) that connect the evaporator (6) and the expansion valve to each other; and a unit case (3) housing the evaporator (6), the expansion valve, and the refrigerant pipes (26, 27), and including an air flow channel (4) for passing air through the evaporator (6). A refrigerant pipe housing chamber (31) is disposed in the unit case (3), and housing the refrigerant pipes (26, 27). The refrigerant pipe housing chamber (31) is partitioned while being isolated from the housing section for the evaporator (6) and the air flow channel (4). The outer circumferential surfaces of the refrigerant pipes (26, 27) are separated from the inner wall surface of the refrigerant pipe housing chamber (31). Furthermore, the thickness (t1) of the wall of the refrigerant pipe housing chamber (31) is greater than the thickness (t2) of the wall of the unit case (3).
