具体实施方式

在本实施例中，散热铝基板1、散热铝块2、第一热管3和第二热管4以锡焊的方式进行连接，使散热铝基板1、散热铝块2、第一热管3和第二热管4形成一个整体。
其中，耐腐蚀材料层为氨基磺酸镍材质，该耐腐蚀材料层还可以是其他耐腐蚀材料，不局限于氨基磺酸镍材质。
在本实施例中，耐腐蚀材料层可以是一层也可以是两层或是三层，本领域技术人员可根据实际情况自行设定。
需要说明的是，本发明不对耐腐蚀材料层的厚度做具体限制，例如，耐腐蚀材料层的厚度为0.2毫米-1.5毫米，本领域技术人员可根据实际情况自行设定。

在本实施例中，第一热管3和第二热管4的结构尺寸相同， 第一热管3的第一端口31和第二热管4的第四端口42不在同一垂直面上，第一热管3的第三端口32和第二热管4的第二端口41不在同一垂直面上。用于适应散热铝块2和散热铝基板1的整体结构，同时不会影响第一热管3和第二热管4的效能。
需要说明的是，本发明不对第一热管3和第二热管4的材质做具体限制，例如，第一热管3和第二热管4均为铜材质，本领域技术人员可根据实际情况自行设定。
如图2所示，在一个实施例中，散热铝块2的下面开有第三凹槽21，用于第一热管3和第二热管4的彼此对接的一端嵌入。通过设置第三凹槽21避免第一热管3和第二热管4移位，使第一热管3和第二热管4被限制在散热铝块2的下面，进而节省空间。
在本实施例中，第一热管3的前部33和第二热管4的前部43贴合后的整体宽度和第三凹槽21的宽度适配，使第一热管3的前部33和第二热管4的前部43抵在第三凹槽21内，避免产生晃动。第三凹槽21的长度略小于第一热管3的前部33长度和第二热管4的前部43长度，这样第一热管3的第一端口31和第二热管4的第二端口41可以裸露于第三凹槽21的外部，且第一热管3的的第一端口31和第二热管4的第二端口41的方向相反，不影响第一热管3和第二热管4效能，使第一热管3和第二热管4产生的接触力互补，进而对散热铝块2冲击较小，助于散热铝块2保持平稳。
具体地，第一热管3和第二热管4的上面、第一热管3和第二热管4的下面均为平面，且第一热管3和第二热管4的内侧面、第一热管3和第二热管4的外侧面同样均为平面，第三凹槽21为矩形槽。其中，第三凹槽21的上面和第一热管3和第二热管4的上面相抵，第三凹槽21的一个侧面和第一热管3的前部33外侧面相抵，第三凹槽21的另一个侧面和第二热管4的前部43外侧面相抵，且第一热管3的前部33内侧面和第二热管4的前部43内侧面相抵。这样第一热管3的前部33和第二热管4的前部43抵靠在第三凹槽21的内部，避免第一热管3和第二热管4产生晃动和在震荡的情况下对散热铝块2产生冲击，进而电路板短路的问题。
可选地，第一热管3和第二热管4的前端均可以凸出于第三凹槽21的端部，也可以是和第三凹槽21的端部齐平，在不影响第一热管3和第二热管4的效能前提下，本领域技术人员可根据实际情况自行设定。
如图2和图3所示，在一个实施例中，散热铝基板1的中部开有镂空结构11，第一热管3和第二热管4的彼此对接的一端均位于镂空结构11内，且散热铝块2焊接固定于镂空结构11。通过设置镂空结构11用于安装散热铝块2、第一热管3和第二热管4，使结构完整，且合理。
需要说明的是，本发明不对镂空结构11的尺寸做具体限制，只要保证散热铝块2、第一热管3和第二热管4安装于镂空结构11的内部，并不和散热铝块2产生间隙即可，本领域技术人员可根据实际情况自行设定。
如图2和图3所示，在一个实施例中，散热铝块2的下面两侧对称设有凸片23，镂空结构11的两侧对称设有第一安装槽12，且凸片23抵在第一安装槽12内，以使得散热铝块2定位。通过设置凸片23和第一安装槽12使散热铝块2被限制于镂空结构11的内部，且散热铝块2嵌入镂空结构11内，避免在外力的作用下产生晃动。
可选地，凸片23为矩形，第一安装槽12同样为矩形，这样凸片23和第一安装槽12可较好配合限位。当然，凸片23和第一安装槽12不局限是矩形，也可以是圆形，具体形状本领域技术人员可根据实际情况自行设定。
如图2和图3所示，在一个实施例中，镂空结构11包括对称设置的第一开口13和第二开口14。其中，第一开口13用于第二热管4插设、并回转于散热铝基板1的上部一侧，第二开口14用于第一热管3插设、并回转于散热铝基板1的上部另一侧，且第二热管4和第一热管3的回转方向相反，以使得第一热管3和第二热管4形成两端对出形式。通过设置第一开口13和第二开口14用于给第一热管3和第二热管4形成两端对出形式提供空间，结构合理。
具体地，第二热管4的中部44布置于第一开口13，且第二热管4的后部45延伸于第二凹槽16内。第一热管3的中部34布置于第 二开口14，且第一热管3的后部35延伸于第一凹槽15内。用于给第一热管3和第二热管4提供回转空间，进而实现两端对出的形式，这样第一热管3、第二热管4和散热铝块2的接触力相等使得散热铝块2保持平稳。
需要说明的是，本发明不对第一开口13和第二开口14的尺寸做具体限制，本领域技术人员可根据实际情况自行设定。
如图2和图3所示，在一个实施例中，散热铝基板1的上部对称开有第一凹槽15和第二凹槽16。其中，第一凹槽15用于第一热管3嵌入，第二凹槽16用于第二热管4嵌入，第一凹槽15和第二开口14贯通，第二凹槽16和第一开口13贯通，以使得第一热管3和第二热管4的彼此抵接的一端均位于镂空结构11内。通过设置第一凹槽15和第二凹槽16将对应的第一热管3和第二热管4隐藏其内部，节省空间，同时不会降低第一热管3和第二热管4效能，安装时也不会与其他器件产生挤压或摩擦，起到保护的作用。
在本实施例中，第一凹槽15和第二凹槽16均为矩形，和第一热管3和第二热管4的形状适配即可，这样第一热管3和第二热管4不会产生松动。
如图2和图3所示，在一个实施例中，控制器还包括多个弹性件5。其中，多个弹性件5等距安装于散热铝块2的下面，以使得散热铝块2形成水平状态。
优选地，弹性件5为弹簧。
具体地，在散热铝块2的下面对称开有多个第二安装槽22，多个第二安装槽22和多个弹性件5一一对应设置，且弹性件5的上端插设于第二安装槽22内。这样散热铝块2保持在一定的水平状态，这样和芯片接触的时候，就不会存在间隙，减少接触热阻，同时由于第一热管3和第二热管4是对称结构，与芯片的接触力也会均匀性更好，避免应力集中导致芯片失效。
本发明第二方面提供了一种车辆，该车辆包括上述的车载热管散热控制器。
本技术方案的车辆包括如本发明任一技术方案的车载热管 散热控制器，因而其具有如本发明任一技术方案的车载热管散热控制器的全部技术效果。
