摘要： A method and device, for a heat exchanger which is provided with gaskets, for assessing and detecting the risk of fluid leakage in the heat exchanger due to worn-out gaskets. In the heat exchanger, a heat transfer plate (5) with gasket (6) is provided with a pressure sensor (15) which monitors the pressure between the plate (5) and the gasket (6). A further sensor (not depicted in the drawings) is adapted to the heat exchanger for monitoring the pressure of the fluid entering the heat exchanger. The sensors' measured values are registered and processed in a processor which calculates a ratio from them. The ratio is a so-called differential pressure value between the measured pressures. The differential pressure value is then compared with a predetermined so-called set-value in order to detect deviations. A differential pressure value differing from the set-value suggests that there is risk that leakage through or round one or more of the heat exchanger's gaskets (6) might occur. Such a situation results in the generating of an indication that the operation of the heat exchanger should be halted so that replacement and servicing of the gaskets (6) can take place without leakage having actually occurred.
摘要翻译：一种用于具有垫圈的热交换器的方法和装置，用于评估和检测由于磨损的垫圈导致的热交换器中的流体泄漏的风险。在热交换器中，具有垫圈（6）的传热板（5）设置有压力传感器（15），该压力传感器监测板（5）和垫圈（6）之间的压力。另外的传感器（图中未示出）适用于热交换器，用于监测进入热交换器的流体的压力。传感器的测量值在计算其比例的处理器中进行注册和处理。该比率是所测量的压力之间的所谓差压值。然后将差压值与预定的所谓设定值进行比较，以便检测偏差。与设定值不同的差压值表明存在可能发生泄漏通过或一个或多个热交换器的垫圈（6）的风险。这种情况导致产生热交换器的操作停止的指示，以便垫圈（6）的更换和维修可以在没有实际发生的泄漏的情况下进行。

摘要： In a plate heat exchanger a stack of double-wall elements (23-26) is included, which between themselves form flow passages (32-34), and each one of which comprises two heat exchange plates, each having a heat exchange portion and a sealing portion surrounding the same and via said portions abutting directly against corresponding portions of the other heat exchange plate. Sealing members (28-31) abut sealingly against adjacent double-wall elements (23-26) along the sealing portions and delimit the flow passages (32-34). Joining means press the double-wall elements against each other. To enable a quick indication of a possible leakage through a heat exchange plate at least one channel (40, 41) is arranged between the plates in each double-wall element. The channel (40, 41) is designed between opposite parts of sealing portions of the respective heat exchange plates and extends across the latter. The channel (40, 41) connects an area inside the sealing portions with the surrounding (35) of the plate heat exchanger. The rest of the sealing portions abuts directly against each other.

摘要： A heat exchanger plate has a primary heat exchange part (1b), two secondary heat exchange parts (2b, 3b) placed on each side of this one and four holes or ports (4b, 5b, 6b, 7b). Two of the ports are located at one of the secondary heat exchange parts in the same distance from but on each side of a centre line (M) of the plate. The two other ports are in a corresponding way located at the other secondary heat exchange part. The plate has in all heat exchange parts (1b, 2b, 3b) ridges and valleys embossed into it, which are so placed that when two plates are put against each other - one of them turned 180 relative to the other one - ridges in one plate intersectingly rest against ridges in the other plate. At least the ridges and the valleys in the secondary heat exchange parts (2b, 3b) are so embossed that they have a volume of essentially the same size on respective sides of the plate. In a plate of this kind each of the two secondary heat exchange parts is provided with ridges and valleys forming an angle with the centre line (M) of the plate. This angle (or these angles) differs from the angle (the angles) which the ridges and the valleys in the primary heat exchange part (1b) of the plate form with the centre line (M). Furthermore, the ridges and valleys of the plate form such angles with the centre line (M) that in a plate interspace they bring about less flow resistance in the areas of the secondary heat exchange parts (2b, 3b) of the plates - on both sides of the centre line (M) - than in the area of the primary heat exchange part (M) of the plates.
