Zusammenfassung:The present invention relates to a method for producing a brazed block (11) for a plate heat exchanger (10), wherein partition plates (4) and heat-conducting structures (2, 3) are stacked together with brazing material (15) in a block (11), the block (11) is subjected in the vertical direction (V) to a first force (F_1) and at the same time, a second section (22) of the block (11) is brought to a tempering temperature (T_R) which is lower than the brazing-material softening temperature (T_L), the block (11) is not subjected in the vertical direction (V) to any force from the outside or is subjected to a second force (F_2), the second section (22) of the block (11) is brought to a brazing-material softening temperature (T_L) at which the brazing material (15) softens, and the first section (21) is brought to a tempering temperature (T_R) which is lower than the brazing-material softening temperature (T_L). The present invention prevents a heat exchange capacity of the plate heat exchanger from being limited. 본 발명은 판형 열교환기(10)용 블록(11)을 제조하기 위한 방법 및 장치에 관한 것으로, 구획 판들(4) 및 열전도성 구조체들(2, 3)이 블록(11)에서 브레이징 재료(15)와 함께 적층되고, 블록(11)은 수직 방향(V)으로 제1 힘(F)을 받게 되고, 블록(11)의 제1 상부 섹션(21)은 브레이징 재료 연화 온도(T)로 가열되고, 그리고 이와 동시에, 블록(11)의 제2 섹션(22)은 브레이징 재료 연화 온도(T)보다 낮은 템퍼링 온도(T)에 도달되고, 그리고 이어서, 블록(11)은 외부로부터 어떠한 힘도 받지 않게 되거나 또는 제1 힘(F)보다 낮은 제2 힘(F)을 받게 되고, 블록(11)의 제2 섹션(22)은 브레이징 재료 연화 온도(T)에 도달되고, 그리고 이와 동시에, 제1 섹션(21)은 브레이징 재료 연화 온도(T)보다 낮은 템퍼링 온도(T)에 도달된다.
