The arrangement of the diverting ribs 44 can make the medium flowing from the diverting area 41 to the main heat exchange area 42 evenly distributed at the diverting ribs 44, which is beneficial for the medium to flow into the main heat exchange area 42 evenly. , and then through the shunt rib 44 between the main heat exchange area 42 and the confluence area 43 for secondary distribution, uniformly collected together, and flowed to the outlet through the confluence area 43 . During the whole process, the medium is evenly distributed on both sides, which can make the medium circulate more evenly in the entire flow channel, which is beneficial to improve the heat exchange formation and ensure long-term heat exchange stability.

另外,由于换热板片的主面板上设有许多波纹形状的凸脊和凹谷,容易发生变形,分流筋44的设置可以为整个换热板提供有效的支撑,提高面板强度,有利于改善加工变形的问题。In addition, since the main panel of the heat exchange plate is provided with many corrugated ridges and valleys, which are prone to deformation, the arrangement of the diverting ribs 44 can provide effective support for the entire heat exchange plate, improve the strength of the panel, and is conducive to improving the Processing deformation problem.

在一种具体的实施方式中,如图2-8所示,分流区41设有若干个凸脊一411,相邻凸脊一411之间形成凹谷一412,凸脊一411与分流筋44之间的夹角为α;主换热区42设有若干个凸脊二421,相邻凸脊二421之间形成凹谷二422,凸脊二421与分流筋44之间的夹角为β;汇流区43设有若干个凸脊三431,相邻凸脊三431之间形成凹谷三432,凸脊三431与分流筋44之间的夹角为γ;α不等于β;β不等于γ。α不等于β,可以使介质不会直接从分流区41流至主换热区42,而是先经过分流筋44的分配再进入主换热区42;β不等于γ,也可以使介质经过分配再进入汇流区43。In a specific embodiment, as shown in FIGS. 2-8 , the diversion area 41 is provided with several ridges 1 411 , a valley 1 412 is formed between adjacent ridge 1 411 , the ridge 1 411 and the diversion ribs are formed. The included angle between 44 is α; the main heat exchange area 42 is provided with several convex ridges 2 421, and valleys 2 422 are formed between the adjacent convex ridges 2 421, and the included angle between the convex ridges 2 421 and the diverting ribs 44 is β; the confluence area 43 is provided with several ridges 3 431, and valleys 3 432 are formed between adjacent ridges 3 431, and the angle between the ridges 3 431 and the diverting ribs 44 is γ; α is not equal to β; β is not equal to γ. If α is not equal to β, the medium will not flow directly from the diverter area 41 to the main heat exchange area 42, but will be distributed by the diverter ribs 44 before entering the main heat exchange area 42; if β is not equal to γ, the medium can also be passed through The distribution re-enters the sink area 43 .

在一种具体的实施方式中,如图8所示,钎焊换热器板片组用于蒸发器,α等于γ,为30-45°,β为20-30°。由于蒸发是液态转换成汽态的过程,将α(或γ)角度设定为较大的角度更有利于液体(或汽态)快速流入(或快速蒸发出)主换热区42,从而提升蒸发性能。In a specific embodiment, as shown in FIG. 8 , the brazed heat exchanger plate group is used for the evaporator, α is equal to γ, which is 30-45°, and β is 20-30°.

在一种具体的实施方式中,如图8所示,钎焊换热器板片组用于冷凝器,α等于γ,为20-30°,β为30-45°。由于冷凝是汽态转换成液态的过程,将α(或γ)角度设定为较大的角度更有利于汽态(或液体)快速流入(或快速流出)主换热区42,从而提冷凝性能。In a specific embodiment, as shown in FIG. 8 , the brazed heat exchanger plate pack is used for the condenser, α is equal to γ, which is 20-30°, and β is 30-45°.
