Description

具有带机加工旁路的挤压多室歧管的换热器
技术领域
本发明总体上涉及一种换热器,更具体地,涉及一种具有带机加工旁路的挤压多室歧管。
背景技术
换热器歧管必须足够坚固以经得起运转时由流过该歧管的流体所施加的升高的压力。许多换热器需要将多个面板放在一起以允许增加的流体流量。这些面板彼此相邻地对齐,并连接到分离的室。因此,存在这样的情况,其中,歧管的相邻室有必要互相流体连通。
已提出具有D形歧管的换热器,其具有单室歧管,典型地用于汽车和商用空调领域。该换热器由相互堆叠的单行管道和翅片组成而形成面板。该面板在每一端被D形歧管盖住。
多室歧管在被挤压时会出现问题,这是因为由挤压工艺制成的歧管不允许流体旁通。在多室歧管是有必要的情况下,室之间的流体连通通常需要在上述D形歧管中的两个或更多个之间的额外旁路。这导致增加流体必须行进的距离,并将外部旁路处的压力增加到不可接受的水平。
当换热器具有多个面板时,单独的集管是不够的。必须具有可以分别地容纳每个面板的歧管,因此需要多个歧管或多室歧管。
发明内容
具有挤压多室歧管的示例换热器包括至少两个面板,每个面板具有连通流体的一行至少一个通道。所述换热器包括第一歧管和第二歧管,所述第一歧管和所述第二歧管每个具有至少两个歧管室。每个面板附接于第一歧管的歧管室和第二歧管的歧管室,每个歧管室具有内壁和外壁。所述外壁具有暴露到所述歧管室外部的表面。还具有穿过外壁并包括旁路槽的开口。所述旁路槽允许室之间流体连通。
具有机加工旁路的示例挤压多室歧管包括至少两个歧管室。所述至少两个歧管室的每一个具有与其附接的面板。歧管室进一步包括内壁和外壁。歧管还具有至少一个旁路槽。在所述歧管的外壁内具有开口,所述开口延伸到旁路槽并由塞子填充。
形成具有内部旁路的挤压多室歧管的示例方法包括挤压具有至少两个歧管室的歧管。在所述歧管室的外壁和内壁内机加工具有座和旁路槽的开口。将塞子插入到所述座内以密封所述歧管室。
本发明的这些和其它特征可从以下说明和附图中得到最佳理解,以下是简要说明。

具体实施方式
参照图1,换热器系统26包括面板22、第一挤压多室歧管16、第二挤压多室歧管18、入口室12、出口室14以及流体源10。流体源10向入口室12提供流体。该流体可为但不限于水、冷却剂或制冷剂。面板22连接到第一挤压多室歧管16和第二挤压多室歧管两者,在它们之间传输流体。流体可在一个方向上、或单程被传输通过该面板,或者在多个方向上、或多程被传输通过该面板。
参照图2-5,并继续参照图1,第一挤压多室歧管16(第二挤压多室歧管18将是类似的)被示出具有内壁40和暴露的外壁42。在歧管16中有至少两个室20,其中内壁40分隔这些室20。内壁40通过挤压形成,使得在没有进一步机加工的情况下在室20之间没有流体连通。开口62被机加工到外壁42的外表面56中并包括座52和旁路槽54。开口62可沿着歧管16的长度被相互隔开预定距离。旁路槽54在歧管16内位于座52内侧。旁路槽54被从内壁40机加工出来并在外壁42内延伸到座52。旁路槽54允许歧管16的室20之间流体连通。旁路槽54可具有与座52不同的尺寸,以允许室20的不同构造和必要的流体连通水平。在生成旁路槽54后,将塞子44插入每个座52内。塞子44可被焊接或通过采用铜焊、树脂粘合或其它已知手段的其他方式固定在适当位置以密封开口62。一旦在座52内,塞子44就密封室20。塞子44可大于旁路槽。塞子44可生成与外壁42平坦的表面。备选地,塞子44可坐落于外壁42之上或之下,生成不平坦的表面。图3-5示出座52、旁路槽54和塞子44的一个构造。其它构造也是可能的。
参照图6A和6B,示出了在挤压多室歧管16、18之间的流体流。图6A示出单程构造,其中流体在面板22内在一个方向上从第二挤压多室歧管18流动到第一挤压多室歧管16。流体可在每个歧管的室20之间通过旁路槽54传输。图6B示出多程构造,其中流体在面板22内在多个方向上运动,并能够在室20之间通过旁路槽54传输。这些实施例示出具有三个室20的歧管16,如上所述可见有槽。
参照图7A,示出了生成具有内部旁路的挤压多室歧管16的方法。用实心的内壁40生成具有室20的挤压多室歧管16。参照图7B,利用切削工具80机加工穿过外壁42并进入内壁40而从内壁40切出包括旁路槽54和座52的开口62。座52可被再次机加工成与旁路槽54不同的尺寸。参照图7C,然后将塞子44插入开口62内以密封歧管室20。塞子44可在插入后被焊接或通过其它手段附接。
备选地,参照图8A,示出了生成具有内部旁路的挤压多室歧管16、18的方法。用实心内壁40生成具有室20的挤压多室歧管16、18。包括的开口62被用切削工具80机加工到外壁42内。机加工的开口62首先包括座52。参照图8B,通过用切削工具80在每个座52内部机加工到内壁40内,从而从内壁40切出旁路槽54。旁路槽54延伸到座52。旁路槽54可为与座52不同的尺寸。参照图8C,然后将塞子44插入座52内以密封歧管室20。塞子44在插入后可被焊接到位。
尽管已公开了本发明的优选实施例,本领域普通技术人员会认识到在本发明范围内可做一定修改。为此,应研究所附权利要求来确定本发明的真实范围和内容。
