  • Publication number: 20060237178
    Abstract: Air passages 18 are formed between surfaces of a plurality of heat transfer plates 12 laid together. A plurality of rib sections 14 extending orthogonal to the air flowing direction A are formed on a surface of the heat transfer plate 12 and projected into the air passage 18. By shifting the positions of the rib sections 14 to each other in the air flow direction, coolant passages 15, 16 are formed inside the plurality of rib sections 14. Between the plurality of rib sections 14, fin sections 17 are formed integral with the heat transfer plate 12 and projected from the plate surface. The fin section 17 has a protruded shape formed by pressing and having a cut portion partially cut a plate thickness of the heat transfer plate 2.

  • Publication number: 20060219396
    Abstract: A lamination-type cooler comprises: a plurality of cooling pipes for interposing and cooling electronic parts; and a pair of refrigerant headers respectively engaged with both end portions of the plurality of cooling pipes, for laminating and fixing the plurality of cooling pipes. Both end portions of a refrigerant passage formed in each cooling pipe are respectively communicated with header passages formed in the refrigerant headers. The cooling pipes are composed so that a plurality of electronic parts can be interposed between the cooling pipes being arranged in a line in a direction perpendicular to the laminating direction of the cooling pipes and also perpendicular to the passage forming direction of the refrigerant passage.

  • Publication number: 20050274496
    Abstract: A boiling cooler includes a refrigerant vessel for reserving refrigerant and a heat radiation unit. A heat-generating member is attached to an outer surface of one of two opposite walls of the refrigerant vessel. The heat radiation unit is mounted at an outer surface of other of the walls. A first wick arranged at an inner surface of the one of the walls extends from a lower portion of the wall to an arrangement position of the heat-generating member when the walls are vertically positioned. Refrigerant boiled and vaporized by the heat-generating member enters the heat radiation unit to be condensed and liquidated, then returning to the refrigerant vessel. The heat-generating member can be effectively cooled regardless of the position of the heat-generating member with respect to the refrigerant vessel, in the cases where the refrigerant vessel is used in the vertical direction and in a horizontal direction.

  • Publication number: 20040093885
    Abstract: A vehicle air conditioner includes a main blower and a sub-blower for blowing air into a passenger compartment. A heat exchange unit for performing a heat exchange with air blown by the main blower is disposed in a case, and the case is provided with a front air passage and a rear air passage. A rear air duct through which air in the rear air passage is introduced to a rear area in the passenger compartment is connected to the case, so that an air flow resistance in the rear air passage becomes larger as compared with the air flow resistance in the front air passage. Further, the sub-blower is disposed integrally with the case for blowing air in the rear air passage to the rear area in the passenger compartment. Accordingly, it can effectively prevent a shortage of an air conditioning capacity in the rear area of the passenger compartment.

  • Patent number: 6669549
    Abstract: A ventilation controlling apparatus using a slide door made of a flexible film member to solve imperfect slide action attributable to film member rigidity degradation on the fringe of an aperture. The slide door is movably disposed inside a casing which forms an air passage, and the slide door is composed of the flexible film member provided with an air-circulation aperture. Ventilation of the air passage is controlled by varying an area of blending or connection between the aperture and the air passage in accordance with movement of the slide door. A rigid support member is fitted around the fringe of the aperture on the film member, thereby enhancing rigidity of the aperture fringe.

  • Patent number: 6360958
    Abstract: In an air conditioning apparatus for a vehicle, an amount of hot water flowing from an engine into a heater core is adjusted by a flow control valve so that temperature of air blown from the heater core is adjusted. A water pump driven by the engine is disposed in a water circuit so that hot water circulates between the engine and the heater core. The flow control valve includes a bypass passage through which hot water bypasses the heater core and a pressure response valve for adjusting an opening degree of the bypass passage. An opening degree of the flow control valve is controlled by a control unit so that the amount of hot water flowing into the heater core is adjusted. In the air conditioning apparatus, the opening degree of the flow control valve is corrected by the control unit to reduce variation in the amount of hot water flowing into the heater core due to variation in a rotation speed of the engine.

  • Patent number: 6311763
    Abstract: In a vehicle air conditioner, a first air passage through which outside air flows and a second air passage through which inside air flows are provided to be partitioned from each other, so that outside air in the first air passage is blown toward a front seat side of a passenger compartment from a front air outlet after passing through a first part of a heat exchanger, and inside air in the second air passage is blown toward a rear seat side of the passenger compartment from a rear air outlet after passing through a second part of the heat exchanger, during a double layer flow mode. Thus, in the second air passage, temperature of air sucked from an inside air port can be set to temperature of inside air inside the passenger compartment, while air pressure loss due to an inside air suction is decreased. As a result, in the vehicle air conditioner, air-conditioning capacity for the rear seat side is improved.

  • Patent number: 5678418
    Abstract: An air-conditioner wherein the lubrication oil flowing through the refrigerant passage along with the refrigerant is reliably returned to the refrigerant compressor by having the refrigerant piping at the suction side of the compressor comprised of a first refrigerant piping and a second refrigerant piping connected in series with the same, the large diameter first refrigerant piping extending from a high position to a low position and the relatively small diameter second refrigerant piping extending in substantially the horizontal direction.

  • Patent number: 5443241
    Abstract: An electro-magnetic drive control valve having a housing defining valve seats 54 and 66, and valve members 68 and 70 arranged so as to face the valve seat 64 and 66, respectively. The valve members 68 and 70 are formed on a valve rod 67, which is mechanically connected to a solenoid actuator 46. First and second diaphragm members 88 and 96 are provided for connecting the valve rod 67 to the housing and for sealing a flow passageway in the housing, while the valve rod 67 is axially moved by the solenoid actuator 46. The first diaphragm 88 is for sealing the flow passageway to the space 104 inside the solenoid actuator 46. The second diaphragm 96 forms a second chamber 107 on one side thereof remote from the flow passageway. An axial opening 67-2 is formed in the valve rod 67 for creating a communication passageway for connecting the chambers 104 and 106 with each other for equalizing the pressure therein.
