Abstract
A plate heat exchanger without straight flow channels is provided, for exchanging heat between fluids. Said heat exchanger, comprises a start plate, an end plate and a number of heat exchanger plates provided with a pressed pattern of ridges and grooves with a pitch. The heat exchanger plates are kept at a distance from each other by contact between ridges and grooves of neighboring plates in contact points, when said plates are being stacked onto one another. Flow channels are thus formed between said plates, the contact points are positioned so that no straight lines are formed along the length of the heat exchanger plates.
