Document Type and Number:
WIPO Patent Application WO/2017/212872
Kind Code:
A1
Abstract:
Provided is an easily cleanable and compact plate-type heat exchanger configured such that the size of at least one fluid inlet/outlet opening is increased while the area of a heat transfer surface is maintained large, thereby enabling high heat transfer efficiency to be maintained.
A plate-type heat exchanger is provided with: a large number of plates (100) having plates which have portions (120, 130) with protrusions and recesses and which are arranged in parallel; and a large number of spacers arranged so as to be sandwiched between the large number of plates. The spacers are provided at edges of plate surfaces at a predetermined distance from each other and comprise: first spacers (200) for forming first flow passages in cooperation with the plate surfaces; and second spacers (300) provided at edges of the plate surfaces at a predetermined distance from each other and forming second flow passages in cooperation with the plate surfaces, the second flow passages having inlet/outlet openings directed in a different direction from the first flow passages. The first spacers and the second spacers are alternately arranged between the large number of plates.
