Embodiment Construction

[0041] It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are provided by way of illustration only, since various changes and modifications within the spirit and scope of the invention will be apparent to those skilled in the art from the details. It's all clear in the description.

[0042] figure 1 A plate heat exchanger 1 is shown comprising a plurality of heat exchanger plates 2 stacked in the stacking direction shown by arrow 3 . The heat exchanger plates are stacked top against bottom.

[0043] figure 2 The heat exchanger is shown in top view with a dimple-type surface structure, which is an exemplary design, but the invention can also be applied to other designs, such as fish skeletons. The heat exchanger plate has four corner openings 4, 5, 6, 7 for connection to the fluid connection mechanism, so that the two openings 5, 7 connect the first fluid supply through one inlet and one outlet. Conne...

Abstract

The present invention relates to a heat exchanger of the kind where a plurality of plates is stacked and where they, due to surface structures, form flow paths between neighboring plates. Particularly, the invention relates to a gasket plate heat exchanger where the plates define gasket holding wavy sections where a gasket is squeezed between two neighbouring heat exchanger plates.

Description

technical field [0001] The invention relates to a heat exchanger of the type in which a plurality of plates are stacked and flow paths between adjacent plates are formed due to surface structures. [0002] In particular, the present invention relates to a gasketed plate heat exchanger, wherein the plates define a gasket holding a corrugated section, wherein the gasket is located and / or squeezed between two adjacent heat exchanger plates. Background technique [0003] A plate heat exchanger uses plates to transfer heat between two media, typically a fluid flowing in separate first and second flow paths. Compared to conventional heat exchangers, the fluid is exposed to a large surface area defined by the plate surfaces. This increases the exchange of thermal energy between the fluids. [0004] Plate heat exchangers are generally used in hot water boilers, in particular for instantaneous preparation of domestic hot water or for heating circuits and the like. [0005] The flo...
