The core part has a plurality of tubes and fins that are alternately arranged with each other, and the protect member is provided at a front side of the core part. The protect member has a plurality of protecting portions extending in a longitudinal direction of the tubes to cover front sides of the tubes of the core part and avoid a collision between the core part and an attack object that is flown from an oblique front side of the motor vehicle toward the core part. | 05-21-2009 |
20090151912 | Composite Heater Core for Vehicles - A composite heater apparatus for vehicles uses integrated tube which is partitioned from a coolant heater core tube part, in which coolant circulates, and an oil cooler tube part, in which engine oil circulates, and includes heat exchanging fin which is in contact with both the coolant heater core tube part and the oil cooler tube part to perform a heat exchanging process. Each header, which is coupled to each of opposite ends of the core tube, is partitioned from coolant circulation space and oil circulation space, via a partition walls. The partition wall includes a surface enlarging member to increase heat exchanging performance using heat conduction. When a vehicle is started in winter, in the initial operation stage of an engine, the vehicle is quickly heated, using the heat of engine oil which is heated prior to engine coolant. | 06-18-2009 |
20090194265 | Heat Exchanger - In a heat exchanger in which the number of parts is small, assembling is easy, bonded portions between each part are fewer and reliability of brazing is improved, a core body is constituted by turning up and bending a strip-shaped metal plate in a fanfold manner, and first flow passages and second flow passages are formed alternately in the thickness direction. Both ends of each of the first flow passages are blocked by each comb tooth of a pair of comb-state members, and a fin is set within the second flow passages so as to constitute a core. And a cylindrical casing is fitted with the outer periphery of the core body, and the casing is constituted by a channel-state material covering three faces of the outer periphery of the core body and a lid material blocking an opening of the channel-state material. In the core body, a starting end and a terminating end of the turning-up/bending of the strip-shaped metal plate are both located on the turned-up end edge on one side, the starting end the terminating end form a fitting edge portion turned-up with the section in the U-shape conforming to the plate thickness of the channel-state material, and the end edge of the opening of the channel-state material is fitted with the fitting edge portion so as to braze/fix the both. | 08-06-2009 |
20090288810 | Heat Radiating Fin - A heat radiating fin includes a flat body, two flange portions formed at two opposite edges of the flat body, and two inward bent locking ends formed at two lateral ends of each of the flange portions to space from the flat body by a distance. When two or more of the heat radiating fins are stacked to form a thermal module, the locking ends of a second heat radiating fin extend beyond the first heat radiating fin via the spaces between the locking ends and the flat body of the first heat radiating fin to upward abut against the flat body of the first heat radiating fin, so that the first heat radiating fin is firmly held to the second heat radiating fin. | 11-26-2009 |
20100071885 | Cover structure for core of heat exchanger - A cover structure for the core of a heat exchanger is provided. The core of a heat exchanger includes a partition plate and a cover. The cover includes a plurality of frames, an upper cover body, and a lower cover body. The upper cover body and the lower cover body join and together define a receiving space for receiving the frames. The frames are disposed on two sides of one of the upper cover body and the lower cover body, allowing the receiving space to be formed between the frames. Each of the frames has a plurality of crosswise extending posts provided therein. Each of the crosswise extending posts extends from an edge thereof, wherein the edge of each of the crosswise extending posts adjoins the receiving space. The crosswise extending posts and the frames together define a plurality of slits. The crosswise extending posts of the frames are coupled to the partition plate directly. The frames and the partition plate are fixed in position within the cover, thereby saving raw materials and reducing the required amount of adhesive material used. | 03-25-2010 |
20120037346 | HEAT EXCHANGER - The preset invention relates to a heat exchanger in which heat transfer between heating water passing through the inside of heat exchanging pipes and combustion gas is efficiently performed. The heat exchanger includes: a plurality of heat exchanging pipes, each of which has an end with an open flat tube-type cross-sectional surface, and through the inside of each of which heating water passes; a first fixing plate and a second fixing plate, each of which has pipe insertion holes formed at a predetermined spacing in the lengthwise direction of the plate, such that both ends of the plurality of heat exchanging pipes are inserted into the respective pipe insertion holes; a first parallel flow channel cap and a second parallel flow channel cap fixed at the respective first fixing plate and second fixing plate to close both ends of the heat exchanging pipes and thus form a parallel flow channel; a heating water inlet connected to the first parallel flow channel cap; and a heating water outlet connected to either the first or second parallel flow channel caps. The cross-section of each of the heat exchanging pipes has protrusions and recessions alternately arranged in the width direction of the heat exchanging pipe, so as to extend the flow path of the combustion gas passing through between the heat exchanging pipes. | 02-16-2012 |

20150300757 | HEAT EXCHANGER TUBE INSERT - A heat exchanger core including a header and a plurality of tubes, each of the tubes having a tube end secured in an opening in a wall of the header to form a tube-to-header joint, a plurality of outer fins capable of transferring heat between a fluid passing through the plurality of tubes and the exterior of the outer fins, the plurality of outer fins being attached between the plurality of tubes and centered about the midpoint in the length of the tubes, the distance from the ends of the plurality of outer fins to the header being a free-of-fin area, and a plurality of resilient tube inserts having a substantially similar cross-section to the cross-section of the plurality of tubes. Each of the resilient tube inserts is inserted into one or more of the tubes at the tube end and secured in the free-of-fin area for the purpose of increasing the tube strength in the free-of-fin area and where the tube passes through, and is attached to, the header. Each of the resilient tube inserts has an outer cross-section dimension greater than the inner cross-section dimension of each tube prior to insertion to enable the tube inserts to remain in place in the free-of-fin area during assembly of a heat exchanger. | 10-22-2015 |
