Therefore, the fourth heat dissipation element 16 is a component in the second mainboard area 13 that has low heat dissipation requirements.
- the first heat dissipation element 4 is a central processing unit
- the second heat dissipation element 5 is a memory stick
- a blocking plate 6 is provided in the front sub-air duct 3 corresponding to at least one of the memory sticks.
- the first heat dissipation element 4 is a central processing unit
- the second heat dissipation element 5 is a memory stick.
- a blocking plate 6 is provided in the front sub-air duct 3 corresponding to at least one memory stick. The heat dissipation of the central processing unit is greater than that of the memory stick.
- a blocking plate 6 is provided in the front sub-air duct 3 where the memory stick is located, so as to reduce the size of the heat dissipation airflow per unit time of the front sub-air duct 3 where the memory stick is located through the blocking plate 6. In the same air guide cover 10, a reduction in the size of the heat dissipation airflow passing through the memory stick will cause an increase in the heat dissipation airflow passing through the central processing unit.
- the setting of the blocking plate 6 actually reduces the partial heat dissipation capacity of the memory stick to relatively improve the heat dissipation capacity of the central processing unit.
- the heat dissipation capacity of the entire heat dissipation device is coordinated and optimized, and further all components in the heat dissipation device can be designed within the standard to meet the needs of users.
- the third heat dissipation component 7 is a power module
- the fourth heat dissipation component 16 is a south bridge chip or an M.2 interface device.
- the second motherboard area 13 is provided with a third heat dissipation element 7, which is a power module.
- the power module is located in the rear air duct 2. After the heat dissipation airflow generated by the fan assembly 17 passes through the front air duct 1, the temperature of the heat dissipation airflow has increased, and the heat dissipation airflow entering the rear air duct 2 has a certain temperature. Therefore, the heat dissipation capacity of the heat dissipation airflow passing through the rear air duct 2 in the related art cannot meet the heat dissipation requirements of the power module. Therefore, a guide cover 8 is provided between the front air duct 1 and the rear air duct 2.
- the guide cover 8 is used to reasonably coordinate and plan the path of the heat dissipation airflow of the front air duct 1 and the rear air duct 2 and the size of the heat dissipation airflow passing through the path, so as to improve the heat dissipation capacity of the heat dissipation airflow to the power module located in the rear air duct 2 and meet the heat dissipation requirements of the power module.
- the selection of the specifications of the blocking plate 6 and the installation position need to be determined based on the fourth heat dissipation element 16.
- the fourth heat dissipation element 16 is a component in the second motherboard area 13 that does not require high heat dissipation, such as a south bridge chip and an M.2 interface device.
- the heat dissipation device also includes a fan assembly 17, and the heat dissipation airflow generated by the fan assembly 17 flows into the front air duct 1.
- the first sub-duct 18, the second sub-duct 19 and the third sub-duct 20 in the front air duct 1 are arranged corresponding to the power module.
- the heat dissipation coordination of the heat dissipation device is improved by planning the paths of the three sub-air ducts.
- the air in the front air duct 1 (the heat dissipation airflow passing through the memory stick and/or the central processing unit) directly enters the two power modules in the rear air duct 2.
- There is always a power module (such as the power module close to the central processing unit in Figure 2) whose temperature value cannot be controlled within the standard, because the heat dissipation airflow passing through the central processing unit has a high temperature rise, and the heat dissipation airflow passing through the central processing unit cannot meet the heat dissipation requirements of its downstream power module.
- the power supply module includes a first power supply module 35 and a second power supply module 36.
- the temperature of the heat dissipation airflow that finally enters the rear duct 2 (leading to the power supply module) through the front duct 1 (the first sub-duct 18, the second sub-duct 19 and the third sub-duct 20) is reduced.
- the first sub-duct 18, the second sub-duct 19 and the third sub-duct 20 are arranged corresponding to the power supply module, so that the temperature of the first power supply module 35 and the second power supply module 36 can be guaranteed to be within the standard during normal operation.
- the guide plate 21 is hinged to the guide plate 22 .
- the guide cover 8 includes a guide plate 21 and a guide plate 22.
- the guide plate 21 is responsible for guiding the heat dissipation airflow of the first sub-air duct 18, the second sub-air duct 19 and the third sub-air duct 20, and the guide plate 22 plays a role in guiding the heat dissipation airflow after being guided by the guide plate 21.
- the guide plate 21 and the guide plate 22 are arranged to be hinged (not shown in FIGS. 7 and 8), the guide plate 22 is fixed, and the guide plate 21 can rotate relative to the guide plate 22.
- the drainage capacity of the guide plate 21 can be adjusted by adjusting the rotation angle of the guide plate 21 relative to the guide plate 22.
- the main function of the guide plate 21 is to merge the heat dissipation airflows of the first sub-duct 18 and the second sub-duct 19, and to proportionally divert the heat dissipation airflow after the merger of the first sub-duct 18 and the second sub-duct 19 and the heat dissipation airflow of the third sub-duct 20, as shown in Figure 3.
- a center line is formed between the second sub-air duct 19 and the third sub-air duct 20, and the guide plate 21 is located on the center line.
- the second sub-air duct 19 is provided with a memory module, and the first sub-air duct 18 is provided with a heat dissipation element with a much smaller heat dissipation than the memory module. Therefore, after the heat dissipation airflow in the second sub-air duct 19 flows through the memory module, the temperature of the heat dissipation airflow flowing out of the second sub-air duct 19 is lower than that of the heat dissipation airflow flowing through the heat dissipation element in the first sub-air duct 18.
- the temperature of the heat dissipation airflow flowing out of the first sub-air duct 18 is relatively high, so the temperature of the second heat dissipation airflow is reduced by the first heat dissipation airflow; and the third sub-air duct 20 is correspondingly provided with the CPU, and the heat dissipation of the CPU is much greater than that of the memory stick, so the temperature of the heat dissipation airflow flowing out of the third sub-air duct 20 is much higher than that of the heat dissipation airflow flowing out of the first sub-air duct 18 and the second sub-air duct 19, and it is necessary to isolate the confluence of the first sub-air duct 18 and the second sub-air duct 19 from the heat dissipation airflow of the third sub-air duct 20, which is achieved by the guide plate 21 of the air guide cover 10.
- the rotation angle of the guide plate 21 is adjusted according to the actual heat dissipation situation.
- the preferred rotation position of the guide plate 21 is that the guide plate 21 is close to the memory stick, and one end of the CPU is located at the center line formed between the second sub-air duct 19 and the third sub-air duct 20, which can effectively isolate the confluence of the first sub-air duct 18 and the second sub-air duct 19 from the heat dissipation airflow of the third sub-air duct 20, and effectively reduce the temperature of the heat dissipation airflow flowing to the third heat dissipation element 7 (power module).
- the guide baffle 23 and the guide flow plate 24 are respectively located on both sides of the guide plate 21, the guide baffle 23 is located on the side corresponding to the third sub-air duct 20, and the guide flow plate 24 is located on the side corresponding to the first sub-air duct 18 and the second sub-air duct 19.
- the guide plate 22 includes a guide baffle 23 and a guide flow plate 24. As shown in FIG7 , the guide baffle 23 blocks the heat dissipation airflow, and the guide flow plate 24 allows the heat dissipation airflow to pass through. After the heat dissipation airflow of the first sub-air duct 18 and the second sub-air duct 19 passes through the guide flow plate 24, the heat dissipation airflow of the first sub-air duct 18 and the heat dissipation airflow of the second sub-air duct 19 will be effectively merged.
- the guide baffle 23 and the guide flow plate 24 are respectively located on both sides of the guide plate 21, and the guide flow plate 24 corresponds to the position of the first sub-air duct 18 and the second sub-air duct 19, and the guide baffle 23 corresponds to the position of the third sub-air duct 20, which can effectively isolate the confluence of the first sub-air duct 18 and the second sub-air duct 19 from the heat dissipation airflow of the third sub-air duct 20, and effectively reduce the temperature of the heat dissipation airflow flowing to the third heat dissipation element 7 (power module).

- the confluence of the heat dissipation airflow of the first sub-duct 18 and the second sub-duct 19 is reversed by the first guide groove 26, so that the heat dissipation airflow of the first sub-duct 18 and the second sub-duct 19 are effectively mixed, so that the heat dissipation airflow of the first sub-duct 18 is used to cool down the heat dissipation airflow of the second sub-duct 19.
- a second guide plate 27 is provided on the side of the guide baffle 23 opposite to the guide plate 21, and a second guide plate 27 is formed between the second guide plate 27 and the guide baffle 23 for changing the direction of the heat dissipation airflow.

- the first guide groove 26 reverses the confluence of the heat dissipation airflow of the first sub-duct 18 and the second sub-duct 19, it is reversed again through the second guide groove 28, so that the heat dissipation airflow flowing through the second guide groove 28 flows to the third heat dissipation element 7 (power supply module), and the third heat dissipation element 7 is effectively cooled by the confluence of the heat dissipation airflow of the first sub-duct 18 and the second sub-duct 19.

本申请涉及服务器领域,特别是涉及一种散热装置和服务器。
随着云计算、大数据等新型技术的发展,对数据存储的带宽和容量要求越来越高,处理器的运算速度与运算量也越来越大,导致内存、硬盘、网卡等各个元器件的温度也不断飙升,电子器件的散热成为目前较为灼手的问题,而且现在社会对功耗的要求也越来越高,节能是目前的一个主流趋势。现在服务器对硬盘、CPU(Central Processing Unit,中央处理器)、网卡的需求越来越高,随着计算量的增加,对应CPU性能的要求越来越高,CPU的功耗也越来越高,对于计算机而言,高功耗的CPU对整个机器的散热设计也是一个瓶颈点。

实施例一
参照图1~图8所示,散热装置包括沿其散热气流方向依次设置的前置风道1和后置风道2,所述后置风道2与所述前置风道1相连通;所述前置风道1包括多个前置子风道3,所述前置风道1内设置有多个第一散热元件4和第二散热元件5,所述第一散热元件4和第二散热元件5分别位于不同的前置子风道3中,所述第一散热元件4在单位时间内的散热量大于所述第二散热元件5在单位时间内的散热量,至少一个所述第二散热元件5对应的前置子风道3内设置有封堵板6;所述封堵板6设置不同规格,不同规格的封堵板6在相应的所述前置子风道3内的横截面积不同;所述后置风道2内设置有第三散热元件7,靠近所述第三散热元件7的前置子风道3为第一子风道18、第二子风道19和第三子风道20,所述第一子风道18、第二子风道19和第三子风道20与后置风道2之间设置有引流罩8,所述引流罩8包括引流板21和导流板22,所述导流板22包括导流隔板23和导流通板24,所述第一子风道18和第二子风道19中的散热气流经过所述引流板21合流后通过所述导流通板24流向所述后置风道2中的第三散热元件7,所述第三子风道20的散热气流经过所述引流板21与所述第一子风道18、第二子风道19分流后通过所述导
流隔板23远离所述第三散热元件7。
为了提高散热装置的协调散热能力,本申请对散热装置内部散热气流的流通路径进行了优化,以提高散热装置整体的散热能力,进一步提高对位于CPU后方的散热部件的散热能力,使得散热装置内部的各元器件的温度都能有效控制在标准以内。散热装置的动力源为风扇组件17,风扇组件17产生散热气流,沿着散热气流的流动方向依次设置有前置风道1和后置风道2,前置风道1与后置风道2相连通,因此风扇组件17所产生的散热气流经过前置风道1后再经过后置风道2。前置风道1内设置有第一散热元件4和第二散热元件5,前置风道1包括多个前置子风道3,第一散热元件4和第二散热元件5分别位于不同的前置子风道3中。第一散热元件4与第二散热元件5相比,第一散热元件4的散热量比第二散热元件5的散热量大,第二散热元件5(散热量需求较小的散热元件)所在的前置子风道3中设置封堵板6,以通过封堵板6来其所在的前置子风道3单位时间内散热气流的大小,同一个前置风道1中,通过第二散热元件5的散热气流的大小降低则会引起通过第一散热元件4的散热气流的增大,因此封堵板6的设置实则是降低对第二散热元件5的部分散热能力,以相对提高对第一散热元件4的散热能力,在保证满足第二散热元件5的散热需求的前提下,协调优化整个散热装置的散热能力,进一步使得散热装置中所有的元器件都能够在设计在标准以内,满足用户的需求。第一散热元件4与第二散热元件5相比,第一散热元件4的散热需求较高,第二散热元件5的散热需求较低,因此可以牺牲对第二散热元件5的散热能力来对散热装置的整体散热效果进行优化。为了进一步提高封堵板6的封堵效率,封堵板6设置不同的规格,不同规格的封堵板6在相应的前置子风道3内的横截面积不同,不同的横截面积对散热气流的封堵效果不同。进一步地,横截面面积越大的封堵板6在同一个前置子风道3内对散热气流的阻力较大,横截面面积越小的封堵板6在同一个前置子风道3内对散热气流的阻力较小,因此可以通过设置不同横截面积的封堵板6来调节封堵板6对其所在前置子风道3内的散热气流的流动阻力。由于封堵板6的设置实则是通过封堵板6对通过其所在前置子风道3的散热气流进行阻挡,即,在保证满足第二散热元件5的散热需求的前提下,牺牲对第二散热元件5的部分散热能力,以相对提高对第一散热元件4的散热能力,因此设置不同规格的封堵板6可以调整封堵板6对其所在前置子风道3内的散热气流的流动阻力,进一步提高对第一散热元件4的散热能力。后置风道2内设置有第三散热元件7,风扇组件17所产生的散热气流经过前置风道1后,散热气流的温度已经升高,进入后置风道2的散热气流已经有了一定的温度,因此相关技术中经过后置风道2的散热气流对第三散热元件7的散热能力无法满足第三散热元件7的散热需求。因此在前置风道1与后置风道2之间设
置引流罩8,通过引流罩8对前置风道1和后置风道2的散热气流的路径以及通过该路径的散热气流的大小进行合理的协调规划,以提高散热气流对位于后置风道2中的第三散热元件7的散热能力,满足第三散热元件7的散热需求。进一步地,前置风道1的路径规划通过第一子风道18、第二子风道19和第三子风道20实现,靠近第三散热元件7的前置子风道3为第一子风道18、第二子风道19和第三子风道20,后置风道2的路径规划通过引流罩8实现。引流罩8设置在前置风道1和后置风道2之间,也就是第一子风道18、第二子风道19和第三子风道20与第三散热元件7之间。风扇组件17所产生的散热气流通过前置风道1的第一子风道18、第二子风道19和第三子风道20进行分流,经过前置风道1,也就是经过第一子风道18、第二子风道19和第三子风道20后的散热气流通过引流罩8进行分流和合流后流入后置风道2。进一步的,如图3所示的散热气流流向示意图,风扇组件17所产生的散热气流部分流经靠近服务器外壳9的第一子风道18,风扇组件17所产生的散热气流部分流经内存条所在的第二子风道19,风扇组件17所产生的散热气流部分流经中央处理器所在的第三子风道20;第一子风道18的散热气流温度最低,第二子风道19的散热气流具有一定的温升,第三子风道20的散热气流温升较高;因此引流罩8将第一子风道18和第二子风道19的散热气流进行合流,以通过第一子风道18的散热气流与第二子风道19的散热气流进行混合以降低第二子风道19的散热气流的温度,并且引流罩8将第一子风道18、第二子风道19的合流与第三子风道20的散热气流分流,使得大部分的温升较高的散热气流流向第二主板区域13中第四散热元件16的区域(只有少部分温升较高的散热气流通过引流罩8与外壳之间的缝隙流向第三散热元件,即,电源模组),而不是直接流向电源模组的散热区域,因此引流罩8对于后置风道2的路径规划实质上是牺牲了部分对第四散热元件16的散热能力,以提高对第三散热元件7的散热能力,路径规划后的第一电源模组35(靠近服务器外壳9)的温度有所升高,但是依然能控制在标准以内,而一直超过标准的第二电源模组36(靠近中央处理器)能够控制在标准以内,路径规划后的后置风道2有效地解决了第三散热元件7(电源模组)的散热能力。实验数据如下,第三散热元件7为电源模组,电源模组包括第一电源模组35和第二电源模组36,在路径未规划前,第一电源模组35的温度为39℃□,第二电源模组36的温度为58℃□,采用本申请的路径规划后,第一电源模组35的温度为42℃□,第二电源模组36的温度为51℃□(标准为55℃□),因此路径规划后的后置风道2有效地解决了电源模组的散热能力,由此可以看出前置风道1上封堵板6的设置,以及通过对前置风道1的路径规划,通过引流罩8对后置风道2的路径规划,整体上对散热装置的散热起到了协调优化的作用,使得主板11上的元器件均能满足标准要求。
本申请对前置风道1和后置风道2的路径,以及流经前置风道1和后置风道2的气流大小进行了协调规划,首先是在第二散热元件5对应的前置子风道3中设置封堵板6,以牺牲对第二散热元件5的散热能力来相对提高对第一散热元件4的散热能力,对前置风道1的散热能力进行了协调优化;前置风道1与后置风道2之间设置引流罩8,通过引流罩8从前置风道1中进入后置风道2的散热气流进行了有效的合流与分流,对后置风道2的散热能力进行了协调优化;通过上述对前置风道1和后置风道2的路径,以及流经前置风道1和后置风道2的气流大小进行的协调规划,整体上降低了第三散热元件7的温度,有效地提高了散热装置整体上的协调散热能力。
在其中一个实施方式中,所述散热装置还包括外壳9,所述外壳9内设置有导风罩10、主板11和所述引流罩8,所述主板11包括第一主板区域12和第二主板区域13,所述第一主板区域12与所述导风罩10、外壳9之间形成前置风道1,所述第二主板区域13与所述引流罩8、外壳9之间形成后置风道2,所述后置风道2与所述前置风道1相连通,所述多个第一散热元件4和第二散热元件5设置在所述第一主板区域12,所述第三散热元件7设置在所述第二主板区域13。
散热装置还包括外壳9(散热装置单独设置外壳9,或者服务器的外壳9充当散热装置的外壳9),外壳9起到对内部元器件的保护作用。外壳9内设置导风罩10、引流罩8和主板11,散热装置的主板11一般分为两部分,即,第一主板区域12和第二主板区域13,第一主板区域12与导风罩10、外壳9之间形成前置风道1,风扇组件17所产生的散热气流首先经过前置风道1。第二主板区域13与引流罩8、外壳9之间形成后置风道2,前置风道1与后置风道2相连通,因此风扇组件17所产生的散热气流经过前置风道1后再经过后置风道2。多个第一散热元件4和第二散热元件5设置在第一主板区域12,第三散热元件7设置在第二主板区域13,即,第一散热元件4和第二散热元件5位于第一主板区域12对应的前置风道1中,第三散热元件7位于第二主板区域13对应的前置风道1中。
在其中一个实施方式中,所述导风罩10包括顶板14,所述顶板14上设置有多个隔板15,相连的两个隔板15之间形成所述前置子风道3,所述封堵板6可拆卸地安装在所述前置子风道3内。
如图4和图5所示,导风罩10包括顶板14和侧板34,当导风罩10安装在散热装置上时,导风罩10的顶板14、侧板34与主板11的第一主板区域12之间形成前置风道1。导风罩10的两个侧板34之间设置有多个隔板15,相邻的两个隔板15与顶板14、主板11的第一主板区域12之间形成前置子风道3。前置子风道3内对应设置不同的散热元件。
进一步地,第一散热元件4和第二散热元件5分别位于不同的前置子风道3中。第一散热元件4与第二散热元件5相比,第一散热元件4的散热量比第二散热元件5的散热量大,第二散热元件5所在的前置子风道3中设置封堵板6(如图所示中设置封堵板6的前置子风道3即第二散热元件5所在的前置子风道3),以通过封堵板6来其所在的前置子风道3单位时间内散热气流的大小,同一个导风罩10中,通过第二散热元件5的散热气流的大小降低则会引起通过第一散热元件4的散热气流的增大,因此封堵板6的设置实则是降低对第二散热元件5的部分散热能力,以相对提高对第一散热元件4的散热能力,在保证满足第二散热元件5的散热需求的前提下,协调优化整个散热装置的散热能力,进一步使得散热装置中所有的元器件都能够在设计在标准以内,满足用户的需求。优选的,封堵板6设置在前置子风道3上靠近风扇组件17的一侧,该侧为风扇组件17产生的散热气流进入前置风道1的进风口,另一侧为散热流经前置子风道3后的出风口,流出该出风口的散热气流经过引流罩8进入后置风道2。
在其中一个实施方式中,所述封堵板6与所述顶板14相连接,和/或,所述封堵板6与其相应的前置子风道3两侧的隔板15相连接。
第一散热元件4与第二散热元件5相比,第一散热元件4的散热需求较高,第二散热元件5的散热需求较低,因此可以牺牲对第二散热元件5的散热能力来提高对第一散热元件4的散热能力。因此封堵板6是设置在相应的第二散热元件5所在的前置子风道3中,如图4和图5所示的封堵板6。封堵板6在其所在的前置子风道3中的连接方式包括三种,第一种是封堵板6与顶板14相连接,第二种是封堵板6与隔板15,第三种是封堵板6同时与隔板15、侧板34相连接。为了便于更换不同规格的封堵板6,封堵板6与隔板15、侧板34之间可拆卸连接,进一步的,封堵板6与隔板15、侧板34之间采用过盈的方式连接,在顶板14、隔板15、侧板34上设置滑动槽,封堵板6的边缘***到滑动槽中,封堵板6的边缘与滑动槽之间过盈连接,防止封堵板6在滑动槽中因散热气流的吹动而活动,封堵板6与滑动槽之间的过盈量允许用户将封堵板6安装到滑动槽中,允许用户将封堵板6从滑动槽中移出。优选的,如图所示,在相邻的两个隔板15之间设置滑动槽,滑动槽的方向沿垂直于散热气流方向向下(沿竖直向下方向),封堵板6的两端***到滑动槽中,滑动槽的底部设置有挡板,用于对封堵板6进行限位。
在其中一个实施方式中,所述第二主板区域13上还设置有多个第四散热元件16,所述第四散热元件16位于所述后置风道2中,所述第四散热元件16至少与其中一个前置子风道3对应设置。
第一主板区域12上设置有第一散热元件4和第二散热元件5,第二主板区域13上除
设置第三散热元件7外,还设置有第四散热元件16,第二主板区域13与引流罩8、外壳9之间形成后置风道2,因此第四散热元件16设置在后置风道2中,并且第四散热元件16至少与其中一个前置子风道3对应设置,以便于前置风道1的散热气流流入到后置风道2对处于后置风道2中的第四散热组件进行散热。
在其中一个实施方式中,所述封堵板6的规格根据所述第四散热元件16的散热需求确定。
为了进一步提高封堵板6的封堵效率,封堵板6设置不同的规格,不同规格的封堵板6在相应的前置子风道3内的横截面积不同,不同的横截面积对散热气流的封堵效果不同。进一步地,横截面面积越大的封堵板6在同一个前置子风道3内对散热气流的阻力较大,横截面面积越小的封堵板6在同一个前置子风道3内对散热气流的阻力较小,因此可以通过设置不同横截面积的封堵板6来调节封堵板6对其所在前置子风道3内的散热气流的流动阻力。如图2所示的散热装置,左侧为第一主板区域12,右侧为第二主板区域13,第一主板区域12上设置有第一散热元件4和第二散热元件5,第一散热元件4和第二散热元件5间隔布置;第二主板区域13上设置有第三散热元件7和第四散热元件16,第三散热元件7位于第二主板区域13的上方,第三散热元件7位于第二主板区域13的下方。第一主板区域12的左侧为风扇组件17,风扇组件17所产生的散热气流经过前置风道1对第一主板区域12的第一散热元件4和第二散热元件5进行散热,流出前置风道1的散热气流进入后置风道2对后置风道2中的第三散热元件7和第四散热元件16进行散热,在前置风道1中设置相应的封堵板6时,由于封堵板6会阻挡其所在前置子风道3内的散热气流,因此会影响位于该封堵板6所在前置子风道3下游的第四散热元件16的散热效果,因此封堵板6的大小需要根据第四散热元件16的散热需求来决定,如果第四散热元件16所需的散热需求并不高,则可以选择横截面积相对较大的封堵板6,如果第四散热元件16所需的散热需求相对高一点,则可以选择横截面积相对较小的封堵板6,需要根据实验数据以及经验值来确定封堵板6的大小,需要对第四散热元件16的散热需求按照一定的标准进行量化,并设置好散热需求与封堵板6的横截面积之间的对应关系,以根据第四散热元件16的散热需求来合理地选择封堵板6横截面积的大小。
在其中一个实施方式中,所述封堵板6的安装位置根据所述第四散热元件16在所述后置风道2中的位置确定。
根据第四散热元件16的散热需求来合理地选择封堵板6横截面积的大小后,需要确定封堵板6的安装位置,与第四散热元件16所对应的前置子风道3可能存在多个,需要选择距离第四散热元件16较近的前置子风道3来安装封堵板6,这样安装后的封堵板6
即使在牺牲了第二散热元件5的散热能力下,其剩余散热能力依旧能够满足对位于前置风道1下游的后置风道2中的第四散热元件16的散热需求。因此第四散热元件16为第二主板区域13中对散热要求不高的元器件。
在其中一个实施方式中,所述第一散热元件4为中央处理器,所述第二散热元件5为内存条,至少一个所述内存条对应的前置子风道3内设置有封堵板6。
第一散热元件4为中央处理器,第二散热元件5为内存条,至少一个内存条对应的前置子风道3内设置有封堵板6。中央处理器的散热量比内存条的散热量大,内存条所在的前置子风道3中设置封堵板6,以通过封堵板6来其所在的前置子风道3单位时间内散热气流的大小,同一个导风罩10中,通过内存条的散热气流的大小降低则会引起通过中央处理器的散热气流的增大,因此封堵板6的设置实则是降低对内存条的部分散热能力,以相对提高对中央处理器的散热能力,在保证满足内存条的散热需求的前提下,协调优化整个散热装置的散热能力,进一步使得散热装置中所有的元器件都能够在设计在标准以内,满足用户的需求。
在其中一个实施方式中,所述第三散热元件7为电源模组,所述第四散热元件16为南桥芯片、M.2接口设备。
第二主板区域13上设置有第三散热元件7,第三散热元件7为电源模组,电源模组位于后置风道2中,风扇组件17所产生的散热气流经过前置风道1后,散热气流的温度已经升高,进入后置风道2的散热气流已经有了一定的温度,因此相关技术中经过后置风道2的散热气流对电源模组的散热能力无法满足电源模组的散热需求。因此在前置风道1与后置风道2之间设置引流罩8,通过引流罩8对前置风道1和后置风道2的散热气流的路径以及通过该路径的散热气流的大小进行合理的协调规划,以提高散热气流对位于后置风道2中的电源模组的散热能力,满足电源模组的散热需求。封堵板6的规格的选择以及安装位置都需要依据第四散热元件16来确定,第四散热元件16为第二主板区域13中对散热要求不高的元器件,如南桥芯片、M.2接口设备。
在其中一个实施方式中,所述散热装置还包括风扇组件17,所述风扇组件17产生的散热气流流入所述前置风道1,所述前置风道1中的第一子风道18、第二子风道19和第三子风道20与所述电源模组相对应设置。
为了能够对散热装置的散热进行协调优化,以保证散热装置内部元器件在正常工作时其温度都能够在标准以内,需要对前置风道1和后置风道2的散热气流路径进一步规划。针对前置风道1的路径规划,靠近第三散热元件7的前置子风道3为第一子风道18、第二子风道19和第三子风道20,通过对三个子风道的路径规划提高了散热装置的散热协
调控制能力。相关技术对电源模组的散热控制中,前置风道1的风(经过内存条和/或中央处理器的散热气流)直接进入后置风道2中的两个电源模组中,始终存在一个电源模组(如图2中靠近中央处理器的电源模组)的温度值不能控制在标准以内,因为经过中央处理器的散热气流温升较高,经过中央处理器的散热气流无法满足其下游电源模组的散热需求。电源模组包括第一电源模组35和第二电源模组36,如图3所示,通过对第一子风道18、第二子风道19和第三子风道20的合理规划,使得最终通过前置风道1(第一子风道18、第二子风道19和第三子风道20)进入后置风道2(通向电源模组)的散热气流的温度降低,第一子风道18、第二子风道19和第三子风道20与电源模组相对应设置,使得第一电源模组35和第二电源模组36在正常工作时都能够保证其温度在标准以内。
在其中一个实施方式中,所述引流板21与所述导流板22相铰接。
引流罩8包括引流板21和导流板22,如图7和图8所示,引流板21负责将第一子风道18、第二子风道19和第三子风道20的散热气流进行引流,导流板22起到了将通过引流板21引流后的散热气流进行导向的作用。为了便于调整引流板21的引流能力,引流板21与导流板22设置为铰接(图7和图8中未示出),导流板22固定,引流板21相对于导流板22可以旋转运动,通过调整引流板21相对于导流板22的旋转角度可以调节引流板21的引流能力。进一步地,引流板21的主要作用是将第一子风道18和第二子风道19的散热气流进行合流,并将第一子风道18和第二子风道19合流后的散热气流与第三子风道20的散热气流进行比例分流,如图3所示的引流罩8前后的散热气流流通路径示意图,如果引流板21向靠近CPU的方向旋转,则允许部分通过CPU的高温气流通过第一子风道18和第二子风道19的合流一并流向第三散热元件7,降低了流向第四散热元件16散热气流的温度,提高了流向第三散热元件7散热气流的温度;如果引流板21向远离CPU的方向旋转,则几乎全部的通过CPU的高温气流通过第三子风道20的流向第四散热元件16,降低了流向第三散热元件7散热气流的温度,提高了流向第四散热元件16散热气流的温度,可以通过引流板21调节散热气流的流通路径,以提高散热装置的协调散热能力。
在其中一个实施方式中,所述第二子风道19和第三子风道20之间形成有中心线,所述引流板21位于所述中心线上。
第二子风道19内对应设置内存条,第一子风道18内对应设置的是比内存条散热量小很多的散热元件,因此第二子风道19内的散热气流流经内存条后,与流经第一子风道18内散热元件的散热气流相比,从第二子风道19流出的散热气流的温度比从第一子风道
18流出的散热气流的温度较高,因此通过第一散热气流降低了第二散热气流的温度;而第三子风道20内对应设置的是CPU,CPU的散热量比内存条大很多,因此通过第三子风道20流出的散热气流的温度比第一子风道18和第二子风道19流出的散热气流的温度高很多,需要对第一子风道18和第二子风道19的合流与第三子风道20的散热气流进行隔离,通过导风罩10的引流板21来实现。根据实际的散热情况进行调整引流板21的旋转角度,引流板21的优选旋转位置为引流板21靠近内存条、CPU的一端位于第二子风道19和第三子风道20之间形成的中心线,能够有效地将第一子风道18和第二子风道19的合流与第三子风道20的散热气流进行隔离,有效地降低了流向第三散热元件7(电源模组)的散热气流的温度。
在其中一个实施方式中,所述导流隔板23和导流通板24分别位于所述引流板21的两侧,所述导流隔板23位于与所述第三子风道20对应的一侧,所述导流通板24位于与所述第一子风道18和第二子风道19对应的一侧。
导流板22包括导流隔板23和导流通板24,如图7所示,导流隔板23对散热气流起阻挡的作用,导流通板24起到让散热气流通过的作用,第一子风道18和第二子风道19的散热气流经过导流通板24后会对第一子风道18的散热气流和第二子风道19的散热气流进行有效地合流。由于引流板21的优选位置为引流板21靠近内存条、CPU的一端位于第二子风道19和第三子风道20之间形成的中心线,因此导流隔板23和导流通板24分别位于引流板21的两侧,导流通板24与第一子风道18和第二子风道19的位置相对应,导流隔板23与第三子风道20的位置相对应,能够有效地将第一子风道18和第二子风道19的合流与第三子风道20的散热气流进行隔离,有效地降低了流向第三散热元件7(电源模组)的散热气流的温度。
在其中一个实施方式中,所述导流通板24上与所述引流板21相对的一侧设置有第一导板25,所述第一导板25与所述导流通板24之间形成有用于改变散热气流方向的第一导流槽26。
为了提高第一子风道18和第二子风道19的散热气流的合流效果,导流通板24上与引流板21相对的一侧设置有第一导板25,第一导板25与导流通板24之间形成有用于改变散热气流方向的第一导流槽26,通过第一导流槽26对第一子风道18和第二子风道19的散热气流的合流的换向,有效地将第一子风道18和第二子风道19的散热气流进行混合,以通过第一子风道18的散热气流对第二子风道19的散热气流进行降温。
在其中一个实施方式中,所述导流隔板23上与所述引流板21相对的一侧设置有第二导板27,所述第二导板27与所述导流隔板23之间形成有用于改变散热气流方向的第
二导流槽28。
导流隔板23上与引流板21相对的一侧设置有第二导板27,第二导板27与导流隔板23之间形成有第二导流槽28,第二导流槽28用于改变散热气流方向。
在其中一个实施方式中,所述第二导流槽28与所述第一导流槽26相连通。
第二导流槽28与第一导流槽26相连通,因此流经第一导流槽26的散热气流会流向第二导流槽28,如图7和图8所示(图7和图8中未标识外壳9,外壳9与引流罩8形成散热气流的流通通道),第一导流槽26对第一子风道18和第二子风道19的散热气流的合流的换向后,通过第二导流槽28再次换向,使得流经第二导流槽28的散热气流流向第三散热元件7(电源模组),通过第一子风道18和第二子风道19的散热气流的合流有效地对第三散热元件7进行散热。
在其中一个实施方式中,所述引流板21的顶部和底部均设置有理线槽29。
相关技术中的前置风道1与后置风道2之间需要布线,而布置的线束在前置风道1之间和后置风道2之间会阻碍前置风道1流向后置风道2的散热气流,影响对后置风道2中散热气流对第三散热元件7的散热效果,因此本申请在前置风道1和后置风道2之间设置引流罩8,不仅能够对散热气流进行合流和分流,而且还能够对线束进行布线,使得线束通过引流罩8顶部和底部的理线槽29走线,降低了线束对散热气流的阻挡作用,提高了对第三散热元件7的散热效果。
在其中一个实施方式中,所述理线槽29处设置有泡棉30,所述泡棉30上设置有穿线槽31。
理线槽29处设置有泡棉30,泡棉30上设置有穿线槽31,线束布置在泡棉30上的穿线槽31中,泡棉30的设置起到了防止漏风的作用,即,防止散热气流的流失。
在其中一个实施方式中,所述导风罩10的两侧与所述外壳9之间设置有泡棉30,所述泡棉30上设置有穿线孔32和避让孔33,部分所述穿线孔32和所述避让孔33的空隙形成所述第一子风道18。
导风罩10的两侧与外壳9之间设置有泡棉30,泡棉30上设置有穿线孔32和避让孔33,部分穿线孔32和避让孔33的空隙形成第一子风道18,此处泡棉30上的穿线孔32用于穿线,避让孔33用于避让泡棉30下方的元器件,线束穿过穿线孔32时会留下间隙,避让孔33与元器件之间也就留下间隙,风扇组件17所产生的散热气流会通过两个间隙形成第一子风道18,以通过第一子风道18的散热气流与第二子风道19的散热气流进行合流,进一步降低第二子风道19的散热气流的温度。其中,位于第一子风道18侧的泡棉30可以采用分体式设计,穿线孔32布置于靠近外壳9的一侧,便于走线,也能够防止
出现泡棉30压线的情况;对于导风罩10另一侧的泡棉30也可以采用分体式设计,在兼顾走线的同时能够对此处的散热气流起到放漏风的作用,即,防止散热气流的流失。
实施例二
参照图9所示,图9为本申请一些实施例提供的服务器的结构示意图。其中,图9所示服务器中,与图1~图8所示结构示意图中相同或相似的内容,可以参考图1~图8中的结构,此处不做赘述。
服务器包括上述散热装置,能够对前置风道1和后置风道2的路径,以及流经前置风道1和后置风道2的气流大小进行协调规划,首先是在第二散热元件5对应的前置子风道3中设置封堵板6,以牺牲对第二散热元件5的散热能力来相对提高对第一散热元件4的散热能力,对前置风道1的散热能力进行了协调优化;前置风道1与后置风道2之间设置引流罩8,通过引流罩8从前置风道1中进入后置风道2的散热气流进行了有效的合流与分流,对后置风道2的散热能力进行了协调优化;通过上述对前置风道1和后置风道2的路径,以及流经前置风道1和后置风道2的气流大小进行的协调规划,整体上降低了第三散热元件7的温度,有效地提高了服务器整体上的协调散热能力。
