It is made up of parallel flat tubes, and a number of fins are inserted between the flat tubes to increase the heat exchange area, and widened portions of the tube wall are provided at both end regions of the flat tube. is in direct contact with the corresponding part of the adjacent pipe and is connected thereto, in particular by soldering, and in each widened part extends transversely to the longitudinal axis of the pipe and has one adjacent flattened part.

This method has already been proposed in No. 0-290899 (Japanese Unexamined Patent Publication No. 175481/1988). Compared to heat exchangers with disk-shaped heat exchangers, this type of heat exchanger does not require the flat tubes to be soldered or glued along their entire length (only the ends and communication ports need to be soldered or glued). This has the advantage that a considerable simplification of manufacture is achieved, since in the proposed construction only the widened end portions of the flat tubes are in direct contact, so that it is not necessary to provide a separate tangential tube sleeve. You can do without it.

パッドの効果は達成されないことになる。[Problems to be Solved by the Invention] However, a heat exchanger having this type of structure has a certain drawback in that the widened portion of the pipe end does not extend over the entire width of the pipe. This is because, when producing widenings of this kind, overstretching of the material leads to cracks, especially in the region of the bent walls at the longitudinal ends of the flat tube. Thereby, as is known from the example of oil coolers in the form of turbulence pads, the known construction does not allow inserting the pad inside the flat tube. The widening section provided in the case of the proposed heat exchanger that does not span the full width only allows the insertion of a turbulence pad that fills only part of the bone width. In such a case, the heat exchange means would flow outside the turbulence pad and the effect of the turbulence pad on improving heat transfer would not be achieved.
本発明は以上のような欠点を除去するためになされたも
ので、乱流パッドが管の全幅を満たしていない管に比較
してより大きい熱交換能力を可能にする熱交換器を提供
することを目的としている。The present invention has been made to eliminate the above-mentioned drawbacks, and it is an object of the present invention to provide a heat exchanger that allows for greater heat exchange capacity compared to tubes in which the turbulence pad does not fill the entire width of the tube. It is an object.

となる。[Means and effects for solving the problem] In order to achieve the above object, according to the present invention, a configuration is adopted in which a turbulence pad that fills the entire width of the tube is provided between the widened portions of the tube of the heat exchanger. has been done. This allows a greater heat exchange capacity compared to tubes where the turbulence pad does not fill the entire width of the tube.

ある。This means that the widened portion of each flat tube extends into a pointed shape toward the narrow longitudinal direction side and forms a bent portion at the longitudinal end edge of the flat tube, so the widened portion extends over the entire width of the tube. This can be achieved by making it possible to be provided. Due to the pointed extension of the widening section towards the end regions, the tube material stretches less in the end regions than in the middle of the parallel tube walls. Overstretching with the risk of cracking therefore does not occur. This design makes it possible in a simple manner to insert a turbulence pad having the width of a flat tube axially into an open tube and to fix it in a known manner. It is also advantageous that no deformation occurs in the narrow end region where the weld seam is generally provided.

ことが証明されている。この方法によれば、このように

されるという利点が得られる。However, it is also possible in other ways to provide the widened section only over part of the width of the flat tube, in which case certain means are provided for inserting the turbulence pad over the entire width of the flat tube. must be established. This means that the turbulence pad is first inserted into the central region of the oblong tube in a zigzag corrugation, and then the region of this tube where the turbulence pad is attached is compressed in parallel, so that the turbulence pad changes from the corrugation to the flattened one. This is achieved by deforming until it is pressed into an elongated shape. In this method, therefore, the flat tube is only formed after the insertion of the turbulence pad. This method has proven to be very advantageous. This method has the advantage that the turbulence pad inserted in this way is initially fixed in the flat tube by deforming the central part of the oblong tube into a plate shape.

点を有する。In this embodiment, the widened portions 2a and 2b of the flat tube 2 are closed off by traps 10 inserted at the end faces. This trap is not provided in the lower two flat tubes in FIG. As is clear from the figure, the central portion 2c of the flat tube 2 is significantly narrower than the widened portion 2a, and a bent portion 8 is provided at the longitudinal edge of the flat tube having parallel walls. transition into parallel walls 4, respectively. Furthermore, as is clear from the figure, openings 6, 6' are provided in the parallel wall sections 4' of the widened section 2a or similar section 2b.
is formed. This parallel wall section 4' is the transition area 9
It transitions downwards through the wall 4 into the wall 4, this transition area being approximately vertical both on the wall 4 and on the wall 4'. This transition region 9 becomes smaller towards the longitudinal ends of the tube, i.e. in each case towards the bend 8, in such a way that the parallel walls 4' initially form a sharp bend towards the bend 8. This is because it is extending. Therefore, the elongation of the material when widening the widened portions 2a, 2b gradually decreases toward the region of the bend 8 and becomes zero in the region of the bend. By means of the pointed widening, the risk of cracking in the region of the bend can be completely avoided, and said widening can be carried out using suitable tools. As shown in FIG. 3, the tubes are provided in good contact with each other, and the turbulence device 7 having the overall width B of the flat tube 2 can be inserted into the flat tube in the axial direction and fixed. has advantages.

開口部を設けることができる。4 to 7 show other embodiments of the flat tube for refrigerant vaporization, and this flat tube is also provided with a turbulent puff door 0. The composition is different. In this example, the end region of the flat tube is not widened and the fourth
As shown in the upper part of the figure, a tube 20' with an oblong cross-section is selected as the starting material, the distance of the walls 40 of this tube from each other being indicated by b. The length of this oval tube 20' is B'. Oval pipe 20 formed in this way
A turbulence pad 70' is inserted in a wavy or zigzag manner within '. The total length of this turbulence pad is set to a length corresponding to the length of the deformed portion after the tube is deformed as described below. This turbulence pad 70', having a length B, therefore extends into the tube 20, as shown in the upper part of FIG. After being inserted axially, this turbulence pad is then deformed. After this transformation has taken place, this central portion 21
is compressed by rollers or a press such that this region of tube 20' has a thickness d and a width B. The widened end region of the flat tube 20 thus formed therefore does not have an overall width B. However, in the region 21 the turbulence pad 70 has a width B over its entire length and, by the deformation process, occupies the expanded position shown in FIG. 4 and is also fixed in this position in the axial direction. Portions 20a and 20b that remain wider than region 21 during this deformation process

Provision has also been made in this embodiment that the opening 60 is provided with an outwardly projecting sleeve 61, which sleeve is formed, for example, by a suitable stamping. This embodiment then has the advantage that only one type of flat tube 20 is required to form the flat tube visualizer or the flat preheat exchanger, and the flat tubes can be soldered together. Here, the sleeve 61 is sized to fit into the opening 60'. As in other embodiments,
