Description

一种散热方法及装置 技术领域  Heat dissipation method and device
本发明涉及中大功率的插箱式系统散热技术领域, 尤其涉及一种散热 方法及装置。 背景技术  The invention relates to the technical field of heat dissipation of a high-power plug-in system, and in particular to a heat dissipation method and device. Background technique
随着集成电路技术的飞速发展, 以大型通讯设备和刀片服务器为代表 的大功率插箱式电子设备的集成度越来越高, 功能越来越复杂, 随之而来 的设备功耗也越来越大, 因此对设备散热的也提出了更高的要求。 但是当 散热风扇的散热量较大时, 其噪声也就越大。 为了满足绿色环保等要求, 需要在满足系统散热要求的前提下, 尽可能优化散热方案, 提高散热效率, 降低散热所产生的功耗和噪声。  With the rapid development of integrated circuit technology, the integration of high-power plug-in electronic devices represented by large-scale communication devices and blade servers is becoming more and more complex, and the functions are becoming more and more complex, and the power consumption of the devices is also increasing. The greater the amount, the higher the requirements for heat dissipation of the device. However, when the heat dissipation of the cooling fan is large, the noise is greater. In order to meet the requirements of environmental protection, it is necessary to optimize the heat dissipation scheme to meet the heat dissipation requirements of the system, improve the heat dissipation efficiency, and reduce the power consumption and noise generated by heat dissipation.
目前最常用的散热方法包括: 整机散热不分区方法, 该方法通过满足 系统中对散热要求最高的器件的散热需求, 来确定风扇的转速。 但是, 由 于设备每个器件对于散热的要求各不相同, 因此, 当满足对散热要求最高 的器件的散热需求时, 风扇的风量超过了实际需求, 从而增加了风扇的功 耗, 也增大了风扇的噪声。  At present, the most commonly used heat dissipation methods include: The whole machine does not partition the heat method, and the method determines the fan speed by satisfying the heat dissipation requirement of the device with the highest heat dissipation requirement in the system. However, since each device has different heat dissipation requirements, when the heat dissipation requirement of the device with the highest heat dissipation is satisfied, the air volume of the fan exceeds the actual demand, thereby increasing the power consumption of the fan and increasing the power consumption. The noise of the fan.
另一种常用的散热方法为整机散热分区方法, 根据不同分区测量的关 键节点的温度来分别确定风扇转速, 即不同分区采用不同的风扇转速, 从 而有效降低散热功耗和噪声。 但是, 该方法中分区之间的隔离度较低, 不 同分区之间风阻差异较大时, 风量会从风阻小的分区走掉, 从而减小了风 阻较大的分区的风量, 影响了风阻大的分区的散热效果, 而为了满足风阻 大的分区的散热效果, 需要增大风扇的风量, 导致散热功率以及噪声的增 加。 因此, 现有技术的散热方法在对整机散热时, 为了满足散热的效果存 在风扇散热功率较大, 噪声较大的问题。 发明内容 Another common heat dissipation method is the heat dissipation partitioning method of the whole machine. The fan speed is determined according to the temperature of the key nodes measured by different zones, that is, different fan speeds are used in different zones, thereby effectively reducing heat dissipation power and noise. However, the isolation between the partitions is low in this method. When the wind resistance difference between different partitions is large, the air volume will be removed from the partition with small wind resistance, thereby reducing the air volume of the partition with large wind resistance and affecting the wind resistance. The heat dissipation effect of the partition is required, and in order to satisfy the heat dissipation effect of the partition with large wind resistance, it is necessary to increase the air volume of the fan, resulting in an increase in heat dissipation power and noise. Therefore, when the heat dissipation method of the prior art dissipates heat to the whole machine, in order to satisfy the effect of heat dissipation, there is a problem that the heat dissipation power of the fan is large and the noise is large. Summary of the invention

图 1为本发明提供的一种散热过程示意图, 该过程包括以下步驟: FIG. 1 is a schematic diagram of a heat dissipation process provided by the present invention, the process comprising the following steps:
S101 : 针对每个被隔离出的物理分区, 监测该物理分区内关键节点的 温度, 其中每个物理分区通过槽位上插入直达背板的单板、 托盘或假面板 被隔离出, 且每个物理分区中包括至少一个槽位。 S101: Monitor, for each isolated physical partition, a temperature of a critical node in the physical partition, where each physical partition is isolated by a board, a tray, or a dummy panel inserted into the backplane through the slot, and each The physical partition includes at least one slot.
具体的, 本发明的散热方法适用于机框中, 按照槽位将机框中的槽位 隔离到不同的物理分区中。 图 2为本发明提供的被隔离出的每个物理分区 的结构示意图。 每两个物理分区之间通过单板、 托盘或假面板等有助于分 区隔离的结构实现隔离, 具体的将单板、 托盘或假面板等有助于分区隔离 的结构插入到槽位上, 将每两个物理分区隔离开。 而且为了保证两个物理 分区之间不相互影响, 进行隔离的单板、 托盘或假面板的深度直达机框的 背板。 风扇位于每个物理分区的一端。  Specifically, the heat dissipation method of the present invention is applicable to the chassis, and the slots in the chassis are separated into different physical partitions according to the slots. FIG. 2 is a schematic structural diagram of each physical partition that is isolated according to the present invention. Each two physical partitions are separated by a structure such as a single board, a tray, or a dummy panel to facilitate partition isolation. Specifically, a structure that facilitates partition isolation, such as a single board, a tray, or a dummy panel, is inserted into the slot. Isolate each two physical partitions. In addition, in order to ensure that the two physical partitions do not interact with each other, the depth of the isolated single board, tray or dummy panel is directly to the backplane of the chassis. The fan is located at one end of each physical partition.
为了保证每个物理分区之间不存在相互影响的风量, 在本发明中单板、 托盘或假面板应该尽可能近的靠近风扇。 较佳地, 单板、 托盘或假面板距 离该物理分区内风扇的距离, 不大于风扇厚度的 1/3 , 并且距离越近越好。  In order to ensure that there is no mutual influence between each physical partition, the veneer, tray or dummy panel should be as close as possible to the fan in the present invention. Preferably, the distance between the veneer, the tray or the dummy panel from the fan in the physical partition is not more than 1/3 of the thickness of the fan, and the closer the distance, the better.
S102: 根据监测到的该物理分区内关键节点的温度, 确定该物理分区 内每个风扇的转速。  S102: Determine, according to the monitored temperature of the critical node in the physical partition, the rotation speed of each fan in the physical partition.
在确定每个物理分区风扇的转速时, 需要监测该物理分区内的关键节 点的温度, 根据监测到的关键节点的温度, 确定该物理分区内每个风扇的 转速。 当该物理分区内没有单板或单板的功率较小时, 监测到的该物理分 区内单板不在位或单板关键节点温度较低, 可以降低风扇的转速或关掉该 物理分区内的风扇。 When determining the speed of each physical partition fan, it is necessary to monitor the temperature of the key nodes in the physical partition, and determine the speed of each fan in the physical partition according to the monitored temperature of the critical node. If the power of the board is not in the physical partition, the board in the physical partition is not in the position or the temperature of the key node of the board is low. You can reduce the speed of the fan or turn off the fan. A fan inside the physical partition.
在本发明中由于每个物理分区之间包括至少一个槽位, 当物理分区中 包括两个以上的槽位时, 为了避免槽位之间风量的相互干扰, 在本发明中 采用该物理分区中每个槽位通过插入直达背板的单板、 托盘或假面板划分 为对应的物理子分区。 即每个物理子分区对应一个槽位, 因此可以避免槽 位之间风量的相互干扰, 更加有利于机框的散热。  In the present invention, since each physical partition includes at least one slot, when the physical partition includes more than two slots, in order to avoid mutual interference of airflow between the slots, the physical partition is adopted in the present invention. Each slot is divided into corresponding physical sub-partitions by a single board, a tray, or a dummy panel inserted into the backplane. That is, each physical sub-partition corresponds to one slot, so that mutual interference of air volume between the slots can be avoided, which is more conducive to heat dissipation of the chassis.
由于本发明中在机框内部, 通过单板、 托盘或假面板等将每个槽位划 分到了被隔离出的物理分区内, 并且单板、 托盘或假面板等直达背板, 因 此可以保证每个物理分区之间的独立性, 避免不同物理分区之间的相互干 扰, 可以确保确定风扇转速的准确性, 避免风扇功率的浪费, 减小风扇的 噪声。  In the present invention, each slot is divided into the isolated physical partition by a single board, a tray or a dummy panel, and the single board, the tray or the dummy panel is directly connected to the back board, so that each can be guaranteed The independence between physical partitions avoids mutual interference between different physical partitions, ensuring the accuracy of fan speed, avoiding waste of fan power, and reducing fan noise.
另外, 在本发明中为了在散热过程中精确控制风扇的转速, 避免风扇 的功率浪费, 使风扇的转速为提供最小风量的转速, 在确定风扇的转速时, 还可以根据考虑环境温度, 根据环境温度以及监测到的物理分区内关键节 点的温度, 确定风扇的转速。 具体的在确定环境温度时, 可以在每个物理 分区的两端, 分别设置温度传感器, 用于监测该物理分区中入风口的温度, 即该风扇刚吹出风的温度, 并监测物理分区出风口的温度, 即风扇吹出的 风经过该物理分区后的温度。  In addition, in the present invention, in order to accurately control the rotational speed of the fan during the heat dissipation process, the power consumption of the fan is avoided, and the rotational speed of the fan is the rotational speed that provides the minimum air volume. When determining the rotational speed of the fan, the ambient temperature may also be considered according to the environment. The temperature and the temperature of the critical nodes in the monitored physical zone determine the speed of the fan. Specifically, when determining the ambient temperature, a temperature sensor may be separately disposed at each end of each physical partition for monitoring the temperature of the air inlet in the physical partition, that is, the temperature of the fan just blowing out the wind, and monitoring the physical partition air outlet. The temperature, that is, the temperature after the wind blown by the fan passes through the physical partition.
