20110024080 | Heat Exchanger - Disclosed herein is a heat exchange apparatus. The apparatus comprises one or more double walled conduit, each having an outer conduit and an inner conduit located coaxially inside the outer conduit. The conduits define a first fluid passageway for cold water at a first temperature. A drain defines a second fluid passageway for grey water at a second temperature and is located in the drain and downstream of the grey water flowing therethrough. The grey water when flowing in the second fluid passageway effects heat transfer to the cold water flowing in the first fluid passageway across the inner and outer conduits. | 02-03-2011 |

The propelling module includes a cylinder, a piston, a second magnet, and a valve. The cylinder is disposed on an inner wall of the box. The piston is disposed in the cylinder, and defines a through hole in a middle portion thereof. The second magnet is fixed to the piston. The valve is fixed in the through hole. The conduits interconnect the cylinder and the box. The first magnet can repel or attract the second magnet, thereby sliding the piston toward the cylinder to close the valve or away from the cylinder to open the valve. | 05-05-2011 |

20140069610 | HEAT EXCHANGER - The tank main body of a header tank of a condenser has slits formed in a circumferential wall thereof at positions between opposite end surfaces of the circumferential wall and heat exchange tubes at the opposite ends. Plate-shaped closure members are inserted into the slits from the outside of the tank main body and joined to the circumferential wall of the tank main body. Drain openings are formed in the circumferential wall of the tank main body at positions on the outer sides of the closure members as viewed in the longitudinal direction of the tank main body. A portion of a surface of each closure member which faces outward in the longitudinal direction of the tank main body forms a portion of a peripheral edge of the corresponding drain opening. | 03-13-2014 |
20140076518 | HEAT EXCHANGE SYSTEM AND METHOD OF USE - A heat exchange system and method of use are provided. The system may include an inlet, an outlet, and a plurality of tubes in communication with the inlet and the outlet. The plurality of tubes may include a first tube located adjacent to a second tube. A first drain conduit may be in communication with the first tube at a location between the inlet and the outlet, and a second drain conduit may be in communication with the second tube at a location between the inlet and the outlet, such that the first and second drain conduits are operable to drain fluid from the plurality of tubes. The method may include supplying fluid to the inlet, flowing fluid through the plurality of tubes, returning fluid to the outlet, and removing a portion of the fluid from the plurality of tubes via a drainage manifold that is in fluid communication with the plurality of tubes at a location between the inlet and outlet. | 03-20-2014 |
20140374062 | OUTDOOR UNIT OF REFRIGERATION APPARATUS - An outdoor unit of a refrigeration apparatus includes a heat exchanger constructed of aluminum or aluminum alloy, a floor frame, and a cap. The heat exchanger has a plurality of flat pipes arranged in rows so as to face a side face, a header manifold connected to each of the flat pipes, and a plurality of fins joined to the flat so that an exchange of heat occurs between a fluid flowing inside the flat pipes and air flowing outside the fiat pipes. The heat exchanger is mounted on the floor frame. The cap covers a lower end part of the header manifold from below the header manifold. The cap has a first drainage structure arranged so that if there is a gap between the header manifold and the cap water that has entered the cap via the gap drains out. | 12-25-2014 |
20150096718 | PLATE HEAT EXCHANGER - A plate heat exchanger comprises first and second frame plates, side walls, and a stack of heat transfer plates. The heat transfer plates each has a center portion and a peripheral portion encircling the center portion, and they are arranged in pairs between the first and second frame plates. A first flow path for a first fluid exists between the heat transfer plates of the pairs and a second flow path for a second fluid exists between the pairs of heat transfer plates. The side walls extend between the first and second frame plates and enclose the stack of heat transfer plates. A first side wall of the side walls includes a through hole for draining a substance, originating from one of the first/second fluids, from inside to outside of the heat exchanger A first portion of the inside surface of the first side wall slopes towards the hole. | 04-09-2015 |
