Abstract

本实用新型是用于换热器中的一种高效强化桥形破口散热片，它是对普通平板散热片的改进，它具有基片，基片上开有若干管孔，其特征是：在基片上冲制有密布的桥形破口；本实用新型中的桥形破口具有强化换热面积和对流体扰流的作用，从而提高了传热系数，主要应用于石油化工、船舶、冶金、舰艇、电力等行业高性能要求的油换热器、气体换热器。

Description

高效强化桥形破口散热片
(一)技术领域：
本实用新型涉及机械制造技术领域，是用于换热器中的一种高效强化桥形破口散热片。
(二)背景技术：
现今制造各类换热器的高效强化散热片绝大多数为光圆管外扎制园环肋片结构，也有一部分为光圆管外套平板散热片结构。现有结构中的冷却介质与被冷却介质仅靠园环肋片或平板散热片强化换热面积，园环肋片在单位体积外形尺寸下强化的换热面积较小，平板散热片虽然在单位体积外形尺寸下强化的换热面积较大，但是平板散热片对介质没有扰流作用，传热系数较小。
(三)发明内容：
本实用新型的目的就是要解决现有平板散热片对介质没有扰流作用，传热系数较小的问题，提供一种高效强化桥形破口散热片。
本实用新型的具体方案是：针对平板散热片进行改进，它包括有基片，基片上开有若干管孔，其特征是：在基片上冲制有密布的桥形破口。
为减小流体流通阻力，本实用新型中，所述基片上冲制的桥形破口均为横向布置。
本实用新型结构简单，其桥形破口对介质具有扰流作用，传热效果好，流体流通阻力小，用于换热器中可提高换热效率。
(四)附图说明：
图1是本实用新型的主视图；
图2是本实用新型的左视图；
图3是本实用新型的俯视图；
图4是图1中的A-A放大视图；
图5是图1中的B-B放大视图。
图中：1-铜片，2-管孔，3-长桥破口，4-短桥破口，5-宽桥破口。
(五)具体实施方式：
参见图1、2、3，本实用新型采用铜片1(长宽按换热器的布置空间需要确定)作基片，在铜片1上冲制若干管孔2(根据换热管的布置确定孔的位置和数量)，特别是在铜片1上还冲制密布的桥形破口，即可制成本实用新型。铜片1上的桥形破口根据布局需要，可分为长桥破口3(参见图4)，短桥破口4(参见图5)，以及宽桥破口5。
