| 20080282725 | Air Conditioner and Manufacturing Method Therefor - To improve the heat transfer performance of a heat exchanger and achieve an air conditioner having high energy efficiency. The heat exchanger | 11-20-2008 |
| 20090301698 | HEAT EXCHANGER OF PLATE FIN AND TUBE TYPE - A heat exchanger including plate fins stacked at respective intervals relative to one another, and heat exchanger tubes penetrating the fins in. The heat exchanger exchanges heat between first and second fluids flowing, respectively, inside and outside the heat exchanger tubes. Each of the fins includes a substantially planar main body and cut-raised portions extending from the main body and disposed at an upstream side of flow of the second fluid. Each of the cut-raised portions corresponds to a respective heat exchanger tube and includes first and second opposed side ends connected to the main body of the fin. The first side end is nearer to the corresponding heat exchanger tube than is the second side end, the first side end is longer than the second side end, and the first side end is disposed at a downstream side of the flow of the second fluid, facing the corresponding heat exchanger tube. | 12-10-2009 |
| 20100205993 | HEAT EXCHANGER ARRANGED IN CEILING-BURIED AIR CONDITIONER AND CEILING-BURIED AIR CONDITIONER - A heat exchanger | 08-19-2010 |
| 20110000254 | HEAT EXCHANGER AND AIR CONDITIONER USING THE SAME - When forming fins and heat transfer tubes by aluminum material, a pressure loss in the tube does not increase and a heat exchanger can be provided having heat transfer performance equal to or higher than a copper tube. The heat exchanger includes fins made of an aluminum material having a low deformation resistance and heat transfer tubes made of an aluminum material having a higher deformation resistance than the aluminum material forming the fins, and on whose internal surface the groove is provided to penetrate the fin to be fixed. It is also arranged that the tube axial direction (a) of the inner surface of the heat transfer tube and the direction (b) of the groove provided on the internal surface of the heat transfer tube are substantially parallel. In this case, the groove direction (b) forms an angle of 0 degrees to 2 degrees with respect to the tube axial direction (a) of the inner surface of the heat transfer tube. The depth of the groove of the heat transfer tube after tube expansion is 0.2 mm to 0.3 mm, and the top width of the ridge top portion is 0.08 mm to 0.18 mm. Further, the number of grooves of the heat transfer tube 20 is 40 to 60, and an apex angle a is 5 degrees to 20 degrees. | 01-06-2011 |
| 20110094258 | HEAT EXCHANGER AND AIR CONDITIONER PROVIDED WITH HEAT EXCHANGER - A heat exchanger provided with a plurality of plate-like fins | 04-28-2011 |
| 20110113820 | HEAT TRANSFER TUBE FOR HEAT EXCHANGER, HEAT EXCHANGER, REFRIGERATING CYCLE APPARATUS, AND AIR CONDITIONER - To obtain a heat transfer tube for a heat exchanger or the like which can obtain predetermined heat transfer performance without increasing in-tube pressure loss. | 05-19-2011 |

| 20090277786 | PLATING PROCESSING LINE - A plating processing line or system includes a plurality of surface processing apparatus including a surface processing apparatus for processing a surface of an object to be treated by introducing a treatment liquid to the surface, and a conveyer unit for conveying the object to be treated, which is disposed between the respective surface processing apparatus linearly or in a curved manner. Each of the surface processing apparatus includes a positioning unit for positioning the object to be treated, which has been conveyed by the conveyer unit to a predetermined position, at which the object is subjected to a pre-plating process or a plating process as a surface processing. | 11-12-2009 |
| 20090321253 | ELECTRODE MOUNTING STRUCTURE OF SURFACE TREATMENT APPARATUS - An electrode mounting structure of a surface treatment apparatus in which a metal electrode is disposed so as to oppose to an inner-peripheral surface of a cylinder, the electrode and the cylinder are energized in a state where treatment liquid is interposed between the electrode and the cylinder inner-peripheral surface so as to perform pre-plating or plating to the cylinder inner-peripheral surface, and the metal electrode is detachably attached to a metal electrode holder member. The structure includes a resin coupler having a threaded portion engaged with a threaded portion formed on the electrode holder member. | 12-31-2009 |
| 20100078326 | PLATING PRETREATMENT APPARATUS AND METHOD FOR CYLINDER BLOCK - The present invention provides an apparatus for plating pretreatment of a cylinder block that includes an electrode performing a plating pretreatment of the cylinder inner wall surface. A gap flow channel communicates with an in-electrode flow channel at a position closest to a seal jig, the gap flow channel being adapted to introduce a treatment liquid to the cylinder inner wall surface, the in-electrode flow channel being adapted to receive the treatment liquid having passed through a communicating hole. The present invention is provided a method for pretreating before plating a cylinder block including disposing an electrode to face the cylinder inner wall surface so as to form a gap flow channel, and introducing a treatment liquid to the gap flow channel thereby flowing through the treatment liquid toward a seal jig and then into an in-electrode flow channel through a communicating hole. | 04-01-2010 |
| 20100104738 | PLATING PRETREATMENT APPARATUS AND METHOD FOR MULTI-CYLINDER BLOCK - A plating pretreatment apparatus for a multi-cylinder block includes a plurality of cylinders that performs a plating pretreatment of a cylinder inner wall surface of each of the cylinders using an electrode disposed so as to oppose to the cylinder inner wall surface by sealing one end of the cylinder inner wall surface and introducing a treatment liquid to the cylinder inner wall surface. In such plating pretreatment apparatus, at least one of a power supply device that supplies electricity to the cylinder block and the electrode and a liquid feed pump that feeds the treatment liquid into a gap between the cylinder inner wall surface and the electrode is provided for each of the cylinders. | 04-29-2010 |
