20100288474 | METHOD AND SYSTEM FOR SEALING AN ANNULUS - A method and systems for a purged seal for an annular space are provided. The purged seal includes a first baffle element that extends from an inner surface of the annular space into the annular space at an oblique angle and a second baffle element that extends from an outer surface of the annular space above the first baffle element in a direction opposite gravity flow into the annular space wherein the second baffle element extends at an oblique angle. The system also includes a third baffle element that extends from the inner surface above the first baffle element in a direction of gravity flow into the annular space wherein the third baffle element extends into the annular space at an oblique angle with respect to the inner surface and wherein a distal end of the third baffle element is positioned proximate a distal end of the second baffle element. | 11-18-2010 |

20110198063 | TUBULAR HEAT EXCHANGER, AND METHOD OF PRODUCING A TUBULAR HEAT EXCHANGER - A tubular heat exchanger includes a substantially cylindrical sheathing tube having a center piece and two end pieces of a length which is shorter than a length of the center piece. Two perforated bases are respectively received in the end pieces and sized to occupy a cross section thereof, and two end caps are respectively secured to axial ends of the end pieces. Extending in substantial parallel relationship inside the sheathing tube between the perforated bases are a plurality of internal tubes to thereby define a first fluid space between an inner surface of the sheathing tube and outer surfaces of the internal tubes, and a separate second fluid space bounded by inner surfaces of the internal tubes and the end caps on the end pieces. A lateral connection pipe is secured to each end piece and fluidly communicates with the first fluid space in a region adjacent to the perforated bases for supply and drainage, respectively, of a first fluid flowing through the first fluid space. The end pieces constitute separate parts which are welded with their axial ends to opposite ends of the center piece and to the end caps. | 08-18-2011 |
20120073790 | WASTEWATER HEAT RECOVERY DEVICE AND METHOD THEREOF - The present invention relates to a wastewater heat recovery device and a method thereof which prevent blockage phenomenon by effectively removing sediment and fine foreign material included in the wastewater. For this purpose, the wastewater heat recovery device comprises: a settling filter unit for settling the sediment contained in the wastewater according to the sedimentation treatment of the wastewater supplied; a heat exchange unit for receiving the wastewater, in which sediment has been removed by passing through the settling filter unit, simultaneously with receiving cold cleans water, and then achieving heat exchange between the wastewater and the cold clean water so as to make hot clean water of the cold clean water; and a filtering unit, which is installed between the settling filter unit and the heat exchange unit, for primarily filtering fine foreign material contained in the wastewater passed through the settling filter unit and then secondly filtering fine foreign material contained in the wastewater passed through the heat exchange unit. In this meantime, the wastewater heat recovery method according to the resent invention, comprises: a settling treatment step of settling the sediment contained in the wastewater according to the sedimentation treatment of the wastewater supplied; a step of primarily filtering fine foreign material contained in the settling treated wastewater; a step of heat-exchanging the primarily filtered wastewater with the cold clean water to make hot clean water of the cold clean water; and a step of secondly filtering the fine foreign material contained in the heat exchanged wastewater. | 03-29-2012 |
20120247738 | DEBRIS PASSAGEWAY FOR WORK VEHICLE COOLING PACKAGE - A debris passage for a cooling box of a work vehicle. Airflow is provided into the cooling box from the exterior environment. A plurality of heat exchangers transfer heat into the airflow. The debris passage is defined between opposing heat exchangers to permit debris to pass from the airflow to the exterior of the cooling box. In one embodiment, the debris passage is underneath an air mover and is substantially vertical. | 10-04-2012 |
20130092356 | TEMPERATURE SYSTEM HAVING AN IMPURITY FILTER - A temperature control system for controlling a temperature of a device under test includes a fluid source and a cooling device reducing a temperature of the fluid supplied by the fluid source and outputting the fluid having the reduced temperature to a device under test. A filter is positioned between the device under test and the cooling device to filter out ice particles that lead to significant charge generation in order to prevent the device under test from being subjected to high voltages as a result of static charge generation. | 04-18-2013 |
20130220583 | LIQUID RESERVOIR AND MANUFACTURING METHOD THEREFOR - A liquid reservoir used in a heat exchanger, for example an automotive air conditioner, and a manufacturing method therefor. The liquid reservoir includes an inlet hole and an outlet hole. The outlet hole is provided with a filter element covering the outlet hole. A flow area at a location of the outlet hole covered by the filter element is greater than the cross-sectional area of other locations of the outlet hole. In this way, in the case that other structures of the inlet hole are not improved, a filtering area of the filter element is increased, thereby increasing a flow area of a refrigerant, reducing a flow resistance effect exerted by the filter element on the refrigerant, and reducing a workload of the heat exchanger. | 08-29-2013 |
20160377351 | HEAT EXCHANGE APPARATUS FOR CIRCULATING FLUIDIZED BED BOILERS - A heat exchange apparatus for circulating fluidized bed boilers is disclosed. The heat exchange apparatus for circulating fluidized bed boilers includes a particle separator configured to separate an exhaust gas and a flow medium discharged from a combustion furnace, an external heat exchanger into which the flow medium collected in the particle separator flows and which is configured to heat a heat transfer medium by heat exchange with the flow medium, and a flow control unit installed at the external heat exchanger and configured to supply air to a flow path of the flow medium and to regulate an internal temperature of the external heat exchanger under the control of a flow direction and a flow quantity of the flow medium. | 12-29-2016 |
