Heat transfer plate and plate pack for a heat exchanger comprising a plurality of such heat transfer plates

Abstract

Heat transfer plates and plate packs are available. The heat transfer plate has first and second opposing sides and includes a first guide section, a third guide section and a fourth guide section. The first guide section and the fourth guide section each comprise a male protrusion as seen from the first side of the heat transfer plate, the male protrusion being arranged to engage with a first adjacent heat transfer plate for heat transfer plate and first adjacent heat transfer plate are aligned, and as seen from the second side of the heat transfer plate, the female recess is arranged to engage with the second adjacent heat transfer plate for the heat transfer plate and the second Adjacent heat transfer plates are aligned. The third guide section comprises a male protrusion as seen from the second side of the heat transfer plate, the male protrusion being arranged to engage with the second adjacent heat transfer plate for the heat transfer plate and the second adjacent heat transfer plate Alignment, and female recess as seen from the first side of the heat transfer plate, the female recess being arranged to engage with the first adjacent heat transfer plate for alignment of the heat transfer plate and the first adjacent heat transfer plate.

Description

technical field [0001] The invention relates to a heat transfer plate and its design. The invention also relates to a plate pack for a heat exchanger comprising a plurality of such heat transfer plates. Background technique [0002] A plate heat exchanger (PHE) typically consists of two end plates between which a number of heat transfer plates are arranged in a stack or group. The heat transfer plates of a PHE can be of the same or different types, and they can be stacked in different ways. In some PHEs, the heat transfer plates are stacked together with the front and back of one heat transfer plate facing the back and front of the other heat transfer plate, and every other heat transfer plate is inverted relative to the rest. Typically this is referred to as the heat transfer plates "rotating" relative to each other. In other PHEs, the heat transfer plates are stacked with the front and back of one heat transfer plate facing the front and back of the other heat transfer ...

Problems solved by technology

Whilst WO 2010 / 064975 discloses a guiding solution that works very well, it is limited to the alignment of heat transfer plates that "rotate" relative to each other
