Patent number: 6705387Abstract: A bracket (300) is coupled to tank caps (122, 222) of header tanks (120, 220), and the bracket (300) is separably attached to a radiator (200) and a condenser (100) by means of hooks (311, 312) and holes (female screw section) (331) for fixing bolts (330). Thereby, it is unnecessary to provide fixing means in a side plate (130, 230) for fixing the bracket (300) thereto. Accordingly, it is possible to reduce the size and the weight of the side plate (139, 230), and easily attach and detach the radiator (200) and the condenser (100) from a vehicle.Type: GrantFiled: September 5, 2001Date of Patent: March 16, 2004Assignee: Denso CorporationInventors: Hiroshi Kokubunji, Tatsuo Ozaki

Patent number: 6705389Abstract: A method and system are disclosed for cooling a heat generating object. A coolant is passed through a heat exchanger so that heated air passing through a first portion of the heat exchanger is cooled. A fan unit is selectively positioned relative to the heat exchanger. When activated, the fan unit draws the cooled air through a second portion of the heat exchanger and directs the twice cooled air towards the heat generating object. The fan unit may be repositioned along a different portion of the heat exchanger so as to redefine the flow of air drawn from and directed towards the heat generating object.Type: GrantFiled: July 17, 2000Date of Patent: March 16, 2004Assignee: Emerson Electric Co.Inventors: Lennart Stahl, Christian Belady

Patent number: 6705390Abstract: Tubes 3 are provided substantially upright on an upper surface of a refrigerant container 2 by inserting lower end portions thereof into inserting holes 5 of the refrigerant container 2. The tube 3A, differed from the tubes 3B, has a trumpet shape which is suddenly increased in its passage cross section towards the lower end opening portion. Thus, most of refrigerant vapor boiled and evaporated in the refrigerant container 2 can be collectively introduced into the tube 3A located within the boiling area. The refrigerant vapor entered a header tank 4 from the tube 3A is diffused in the header tank 4, and is introduced into the tubes 3B located out of the boiling area. The condensate produced by cooling the refrigerant vapor upon passing through the tubes 3B can be circulated into the refrigerant container 2.Type: GrantFiled: October 24, 2002Date of Patent: March 16, 2004Assignee: Denso CorporationInventor: Takahide Ohara

Patent number: 6705391Abstract: A heat exchanger includes a metal fin assembly and metal tubing for carrying a heat exchange fluid. The tubing is located in passages of the assembly. Films bridge gaps between the tubing exterior surfaces and interior wall surfaces of tubes that form the passages. Exposed, exterior surfaces of the fin assembly and tubing are coated. The films and coatings are formed by electro-depositing electrically insulating powder on the heat exchanger exposed exterior surfaces. The film bridges the gap to prevent transfer of fungi and/or bacteria across the gap. The coating and film are very smooth to reduce the tendency for fungi and bacteria to accumulate. The powder can include an agent having antifungal and/or antibacterial properties.Type: GrantFiled: October 19, 2001Date of Patent: March 16, 2004Inventor: Scott J. Lewin

Patent number: 6705392Abstract: A plurality of water passages allowing flow of water, a plurality of alcohol passages allowing flow of alcohol and a plurality of high temperature gas passages heating the water passages and the alcohol passages are independently provided in a heat exchanging portion. Liquid alcohol is supplied from a first header to the alcohol passage and water is supplied from a second header to the water passage. The water passage is preferably adapted to make contact with a high temperature section of the high temperature gas passage and the alcohol passage is preferably adapted to make contact with the low temperature section of the high temperature gas passage. By separately vaporizing water and alcohol in this way, the mixing ratio of the water vapor and alcohol vapor can be controlled with high response.Type: GrantFiled: January 8, 2002Date of Patent: March 16, 2004Assignees: Nissan Motor Co., Ltd., Calsonic Kansei CorporationInventors: Takaharu Gotou, Hiroyuki Yoshida

Patent number: 6705393Abstract: A ceramic heat sink having a micro-pores structure includes a heat dissipation layer, and a thermal conductive layer. The heat dissipation layer forms a ceramic micro-cell structure, which is combined with a sub-micrometer powder, thereby forming the heat dissipation layer. The thermal conductive layer is mounted on the heat dissipation layer to contact with a heat source. Thus, the thermal conductive layer absorbs the heat energy from the heat source; the heat dissipation layer has a micro-pores structure with hollow crystals, and the air functions as the media of heat dissipation, so that the heat dissipation capacity of the ceramic heat sink is greatly enhanced.Type: GrantFiled: February 25, 2003Date of Patent: March 16, 2004Assignee: ABC Taiwan Electronics Corp.Inventor: Chaby Hsu

Patent number: 6705394Abstract: Rapid thermal cycling of substrates in low-pressure processing environments is achieved by movable temperature conditioners located outside the processing environments. The substrates are mounted on thermally conductive pedestals for processing in the low-pressure environment. The temperature conditioners are movable both into and out of thermal contact with the pedestals outside the low-pressure environment to regulate transfers of heat through the pedestals between the substrates and the temperature conditioners. A translatable cooler block with a high thermal mass and a large interface area with the pedestal can be used as a temperature conditioner for more rapidly withdrawing heat from the substrate.Type: GrantFiled: September 19, 2000Date of Patent: March 16, 2004Assignee: CVC Products, Inc.Inventors: Mehrdad M.

Patent number: 6705396Abstract: A method and apparatus for producing fluid cavitation is provided. For a given channel cross-section of a pressure line, the flow is accelerated so as to reach a speed at which Re>Recr, where Re is the Reynolds number and Recr is the critical Reynolds number; the flow is then interrupted for a time less than half of the phase of the hydraulic shock. The device for cavitation of fluid flow is mounted in the channel of a pressure line and includes a cavitator which has the form of a working body placed in the casing and can move radially inside the line and, to a limited extent, along the axis of the line. The maximum cross-section surface of the working body in a plane perpendicular co the axis of the line is more than 0.8 of the passage of the line but not equal to it.Type: GrantFiled: April 2, 2002Date of Patent: March 16, 2004Assignee: BIP Technology LtdInventors: Vladimir Ivanovich Ivannikov, Ivan Vladimirovich Ivannikov
