Problems solved by technology

With such and similar measures, it has been found that there is a disadvantage that when one wants to braze generally differently designed products in a brazing furnace, the flow guides need to be designed for different products, thereby causing great expense

Embodiment Construction

[0026] according to figure 1 , the brazed heat exchanger—which in this embodiment is a condenser—consists of a block 1 consisting of flat tubes 2 and fins 3 not shown between the flat tubes 2 . At opposite ends of the flat tubes 2, a header 4 is fixed in each case. The collecting pipe 4 on the left in the figure is connected with an additional pipe 5, which is arranged in parallel with the collecting pipe with a small gap. Since, as previously mentioned, a condenser is involved, the additional pipe 5 will subsequently be referred to as the dryer drum 5 .

[0027] The dryer cylinder 5 includes a protruding connector 51 arranged in a line to achieve the desired connection. There are invisible openings (57, Figure 5 ), through which refrigerant can enter the dryer cylinder 5 from the header 4 and exit from the dryer cylinder 5 through another connection 51 .

[0028] according to figure 1 , the visible outer surface 50 of the dryer cylinder 5 is configured to enlarge it. ...

Abstract

A brazed heat exchanger, having a block consisting of flat tubes and fins, having header tubes arranged at opposite ends of the flat tubes and having an additional tube, which is connected to one of the header tubes. To reduce brazing defects, provision is made for at least a significant part of an outer surface of the additional tube and / or of the header tubes to be of enlarged design.

Description

technical field [0001] The present invention relates to a brazed heat exchanger comprising: a block made of flat tubes and fins; headers arranged on opposite ends of the flat tubes; and additional tubes connected to the headers. A connection in the tube. Background technique [0002] Such brazed heat exchangers are known from EP1147930B1 and many other publications, in the case of such a heat exchanger as a condenser, which is used as an integral part of air conditioning equipment, for example by cold air flow, The circulating refrigerant is condensed cyclically. [0003] The brazing is carried out in a brazing furnace into which the aforementioned heat exchangers are introduced after corresponding pre-assembly and pre-treatment and, usually in a single brazing operation production. That is, all connections are brazed in said one brazing operation. [0004] Usually there are some brazing technical problems. The reasons for this are varied and often difficult to pinpoint...
