| 摘要 |
<p>The invention relates to a hating unit comprising a plate heat exchanger (10) having a plurality of heat exchanger plates combined to form a plate stack defining flow passages of a primary circuit (15) having a heat-emitting liquid inlet (11) and a heat-emitting liquid outlet (13) and flow passages of a secondary circuit (16) having a heat-absorbing liquid inlet (14) and a heat-absorbing liquid outlet (12), a heat-emitting liquid supply channel (61) for guiding heat-emitting liquid from a heat-emitting liquid supply line to the heat-emitting liquid inlet (11), a heat-emitting liquid discharge channel (63) for guiding heat-emitting liquid from the heat-emitting liquid outlet (13) to a heat-emitting liquid discharge line, a heat-absorbing liquid supply channel (64) for guiding heat-absorbing liquid from a heat-absorbing liquid supply line for supplying heat-absorbing liquid to the heat-absorbing liquid inlet (14), and a heat-absorbing liquid discharge channel (62) for guiding heat-absorbing liquid from the heat-absorbing liquid outlet (12) to a heat-absorbing liquid discharge line, wherein the heat-emitting liquid supply channel (61) and the heat-absorbing liquid discharge channel (62) are adapted and arranged to enable heat transmission from heat-emitting liquid in the heat-emitting liquid supply channel (61) to heat-absorbing liquid in the heat-absorbing liquid discharge channel (62), wherein the heating unit comprises a middle plate (20) and an end plate (40) having openings (31, 32, 33, 34) and/or pressed indents defining the heat-emitting liquid supply channel (61) and the heat-absorbing liquid discharge channel (62).</p> |
