Problems solved by technology
However, because tubes with larger widths tend to bulge and collapse, especially during high-voltage pulse loads, fused tubes can only be made with a maximum width in the range of 14 mm to 20 mm

Embodiment Construction
[0072] Figure 1a and 1b An assembly 2 of a tube element 3 (in particular a flat tube) with a tube plate 5 and a sealing element 7 of a heat transfer device is shown. exist Figure 1a , a detailed view of a heat transfer device 1 with an assembly 2 of tube elements with spaced cooling fins 4, tube sheets 5 and sealing elements 7 and a collector 9 as a separate component is shown in an exploded view . When coolant is used as the fluid, the collector 9 is also referred to as a coolant collector. exist Figure 1b In , the assembly 2 of the tube element 3 with the tube plate 5 and the sealing element 7 is depicted in the installed state and in the state of the individual components.
[0073] Depending on the power requirement, the module 2 constructed from flat tubes 3 is implemented as a single-row or multi-row module and is scalable in size, which means especially in length or width. Figure 1a The pipe elements 3 shown in are arranged in two rows, while Figure 1b A sing...

Abstract
The present invention relates to a device (1) for heat transfer between a first fluid and a second fluid. The device (1) comprises an assembly (2) comprising: tube members (3, 3a, 3b, 3c, 3d) configured such that the first fluid passes through the same; one or more tube bottom portions (5, 5a, 5b) having penetration openings (6, 6a, 6b); and one or more sealing members (7, 7a, 7b) having penetration openings (8, 8a, 8b). The tube members (3, 3a, 3b, 3c, 3d) are formed to comprise undeformed first areas (15a, 15b, 15c, 15d) and one or more deformed second areas (16a, 16b, 16c, 16d) arranged onone end portion of the tube members (3, 3a, 3b, 3c, 3d), respectively. The sealing members (7, 7a, 7b) are arranged between the outer surface of the second areas (16a, 16b, 16c, 16d) of the tube members (3, 3a, 3b, 3c, 3d) and the edge of the periphery of the penetration openings (6, 6a, 6b) of the tube bottom portions (5, 5a, 5b), respectively. The tube members (3, 3a, 3b, 3c, 3d) are formed as flat plate tubes so as to have flow channels configured such that the first fluid passes through the same. In this case, the flow channels are separated from each other by one or more inner structure members. The flat plate tubes are made of a metal. The tube members (3, 3a, 3b, 3c, 3d) have sections expanded inside a plane aligned perpendicularly to the longitudinal direction (x) in the second areas (16a, 16b, 16c, 16d). The present invention also relates to a system and a method for manufacturing the device (2).
Description
technical field [0001] The invention relates to a heat transfer device, in particular for use in a motor vehicle. Here, heat is preferably transferred between a coolant (for example water or a mixture of water and glycol) as the first fluid and air as the second fluid. The device comprises an assembly of tube elements for conducting a first fluid and at least one tube sheet having passage holes for the tube elements to pass through the tube sheet. [0002] Additionally, the present invention relates to systems and methods for fabricating heat transfer devices. Background technique [0003] Coolant-air heat exchangers known from the prior art for transferring heat from the coolant of the coolant circuit to the surrounding air are used in so-called high-temperature coolant circuits for removing heat from the internal combustion engine. A coolant-to-air heat exchanger made of aluminum consists of: a number of tubes fixed in a tube sheet; and fins and side elements and coolant...
