具体实施方式
本发明的核心是提供一种散热控制方法，使得散热通道中各器件尽可能少的工作在高温条件下，消除了相关器件安全隐患且延长了使用寿命；本发明的另一核心是提供一种散热控制装置以及设备，使得散热通道中各器件尽可能少的工作在高温条件下，消除了相关器件安全隐患且延长了使用寿命。
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参考图1，图1为本发明提供的一种散热控制方法的流程示意图，该散热控制方法包括：
步骤S1：根据散热通道中各个器件的功耗值计算出散热通道的产热速度；
具体的，考虑到如上背景技术中的技术问题，同时由于申请人考虑到了在散热通道中温度的提升来源主要是器件通电时的电热转换，但是这个升温的过程并不是瞬间完成的，因此可以在升温之前及时地检测出散热通道中各个器件的功耗值对应的产热速度，并针对性地进行防止升温的处理。
其中，散热通道可以指的是散热器的散热介质所流经的通道，例如可以是风扇的风道或者是液冷散热装置的水流通道等，本发明实施例在此不做限定。
具体的，各个器件可以指的是可以进行能量转换产生热能的器件，例如可以包括CPU、GPU(Graphics Processing Unit，图形处理器)以及导线等，本发明实施例在此不做限定。
步骤S2：根据散热通道的温度值以及散热介质的实际单位时间流量计算出散热通道的散热速度；
具体的，为了对散热器进行控制以使得散热器的散热速度与散热通道的产热速度相匹配，那么须首先了解在散热器作用下，散热通道当前的散热速度，从而可以在当前的散热速度的基础之上对于散热器进行控制以便实现匹配。
具体的，散热通道的温度值可以反映出在散热器散热作用下的散热通道的温度变化，而散热介质的实际单位时间流量也与散热速度直接相关，因此可以根据这两个数据准确地计算出散热通道的散热速度。
当然，除了根据上述两个数据计算散热通道的散热速度外，散热通道的散热速度还可以采用其他方式进行计算，本发明实施例在此不做限定。
步骤S3：根据产热速度以及散热速度的差值确定出散热器的第一参数调整量；
具体的，产热速度与散热速度的差值可能为任意情况，该差值也可能为零，当产热速度减去散热速度的差值为正数时，说明散热通道内各器件的功耗增加了，散热通道内各器件的产热能力增加，此时需要提升散热器的功耗以便使得散热速度匹配上产热速度，在散热通道内各器件升温之前 对其温度进行压制，而当产热速度减去散热速度的差值为负数时，说明散热通道内各器件的功耗降低了，散热通道内各器件的产热能力减弱，此时需要降低散热器的功耗以便使得散热速度与产热速度相匹配，以免造成能源的浪费。
其中，当产热速度以及散热速度的差值不为零时，均需要根据该差值对于散热器进行控制，而对于散热器的控制其实指的是对于散热器的运行功耗进行调整，因此需要根据产热速度以及散热速度的差值确定出来散热器的第一参数调整量，以便后续步骤基于该调整量对于散热器进行控制。
其中，参数指的是与散热器所能提供的散热能力相关的参数，例如当散热器为风扇时，参数可以指的是风扇的转速等，本发明实施例在此不做限定。
步骤S4：根据第一参数调整量对散热器进行控制，以便散热速度与产热速度匹配。
具体的，在确定出对散热器的第一参数调整量之后，便可以根据第一参数调整量对于散热器进行控制，从而可以使得散热速度与产热速度相匹配，使得散热通道内各器件的温度始终保持在稳定健康的区间，有利于服务器的稳定运行且降低相关器件损坏的概率。
其中，本发明实施例中的散热控制方法可以每隔预设时段执行一次，以便持续地保持散热通道内各器件运行在健康稳定的温度值区间内。
具体的，值得一提的是，本申请还可以在关键器件(例如CPU以及GPU等)上设置温度传感器对其温度进行监测以及提示，并可以进行超温报警等，以便在温度控制错误时确保关键器件的安全。
具体的，在减少了器件高温状况的情况下，也相当于减少了风扇高速运转的时间，也就减少了***噪音，提升了用户体验。
本发明提供了一种散热控制方法，本申请可以根据散热通道中各个器件的功耗值计算出该散热通道的产热速度，然后基于该产热速度对散热器进行控制以便该散热通道的散热速度与产热速度匹配，由于在实际温度提升之前，其通常存在功耗较高也即温度提升的一段时间，本申请在该时间段内便可以进行散热速度的匹配以便压制散热通道中各器件的温度提升， 使得散热通道中各器件尽可能少的工作在高温条件下，消除了相关器件安全隐患且延长了使用寿命。
在上述实施例的基础上：
作为一种优选的实施例，根据散热通道中各个器件的功耗值确定出散热通道的产热速度具体为：
获取散热通道中各个非运动器件的功耗值；
根据各个功耗值之和计算出散热通道的产热速度。
具体的，考虑到散热通道中除了大部分会将能量转换为热能进行温度提升的器件外，还存在一些器件会将能两个转换为动能，例如用于散热的风扇等，在进行产热速度计算的时候不应参考这部分运动器件的功耗值，因此本发明实施例中首先可以获取散热通道中各个非运动器件的功耗值，然后基于非运动器件的功耗值进行散热通道的产热速度的计算。
具体的，根据各个功耗值之和计算出散热通道的产热速度可以为：
计算出各个器件的产热功耗；
将各个器件的产热功耗之和作为产热速度；
其中，各个器件的产热功耗的计算方式可以为电压U乘以电流I，那么该器件在T时间段内产生的热量Q＝U*I*T。
具体的，上述的电压可以为固定值，而电流值的实时数值可以通过电流传感器进行采集，本发明实施例在此不做限定。
当然，除了上述计算方式外，各个器件的产热功耗的计算方式还可以为其他多种类型，本发明实施例在此不做限定。
作为一种优选的实施例，根据散热通道的温度值以及散热介质的实际单位时间流量计算出散热通道的散热速度具体为：
V 散热＝C×CFM×ρ×ΔT；
CFM＝V×S；
其中，V 散热为散热速度，C为空气比热容，CFM(Cubic Feet per Minute，立方英尺每分钟)为散热通道的散热介质的实际单位时间流量，ρ为散热 介质的密度，ΔT为散热通道中散热介质的入口温度以及出口温度的温度差值，V为散热介质的流速，S为散热通道的截面积。
具体的，通过上述公式可以准确地对散热速度进行计算。
当然，除了上述公式外，计算散热速度的公式还可以为其他多种类型，本发明实施例在此不做限定。
具体的，散热通道中散热介质的入口温度以及出口温度均可以通过温度传感器采集得到，而散热介质的流速可以通过风速传感器(散热器为风扇时)等进行采集，本发明实施例在此不做限定。
作为一种优选的实施例，散热通道为多个；
获取散热通道中各个非运动器件的功耗值具体为：
获取目标散热通道中各个非运动器件的功耗值；
根据各个功耗值之和计算出散热通道的产热速度具体为：
根据各个功耗值之和计算出目标散热通道的产热速度。
具体的，当服务器中的散热通道为多个时，本申请中的散热控制方法可以针对各个散热通道所对应的散热器进行控制，也就是说本申请可以对服务器中的多个散热器进行针对性地区分控制，而无需像现有技术中一样进行统一的控制，一方面可以降低功耗，另一方面可以保证各个散热通道的温度值均稳定在健康的温度值区间。
作为一种优选的实施例，散热器为风扇；
则散热通道为风道，散热介质为空气。
具体的，风扇为常见的散热器，其具有成本低以及结构简单等优点。
当然，除了风扇外，散热器还可以为其他多种类型，本发明实施例在此不做限定。
作为一种优选的实施例，应用于独立于散热器所在服务器的处理器。
具体的，采用独立于散热器所在服务器的处理器执行上述散热控制方法对应的程序，可以减轻BMC(Baseboard Management Controller，基板管理控制器)的压力，以便其更好地运行其他业务。
其中，处理器可以为多种类型，例如可以为单片器或者ARM(Advanced RISC(Reduced Instruction Set Computing，精简指令集计算机)Machines，高级精简指令集处理器)处理器等，本发明实施例在此不做限定。
作为一种优选的实施例，散热通道对应的散热器为多个；
则根据第一参数调整量对散热器进行控制具体为：
以散热通道对应的多个散热器的能量转换效率总和最高为目标，根据第一参数调整量对散热通道对应的多个散热器进行控制。
具体的，由于散热器运行在不同的功耗下，其能量转换效率存在较大差别，当能量转换效率较低时则相当于造成了能量的浪费，例如当散热器为风扇的时候，风扇的转速如果太高的话，那么其能量转换效率是较差的，因此本发明实施例中可以在当散热通道对应的散热器为多个的时候，以散热通道对应的多个散热器的能量转换效率总和最高为目标，根据第一参数调整量对散热通道对应的多个散热器进行控制，例如一种情况下可以为：当风扇为3个的时候，若其中两个风扇均运行在最高的能量转换效率对应的风速下，另外一个风扇不用工作即可满足当前的散热需求，那么此时便可以控制其中两个风扇运行在最高的能量转换效率对应的风速下，另外一个风扇不用工作，从而使得该散热通道对应的散热器的能量转换效率最高，相当于以最少的电能来提供所需求的风速，降低了能源的消耗。
当然，除了上述列举的实例外，以散热通道对应的多个散热器的能量转换效率总和最高为目标，根据第一参数调整量对散热通道对应的多个散热器进行控制还可以为其他具体形式，本发明实施例在此不做限定。
作为一种优选的实施例，根据第一参数调整量对散热器进行控制之后，该散热控制方法还包括：
计算实际单位时间流量相对于散热器当前的理论单位时间流量的单位时间流量补偿值；
根据单位时间流量补偿值生成对于散热器的第二参数调整量；
根据第二参数调整量对散热器进行控制，以便使得实际单位时间流量等于理论单位时间流量。
具体的，考虑到在散热通道的结构不同时，其对散热介质构成的阻力也不同，该阻力同样会对散热速度产生影响，例如原本欲控制风扇工作在1000转每分钟，但是由于散热通道的阻力太大，风扇仅仅工作在800转每分钟的工况下，相应的其实际单位时间流量相对于1000转/min所对应的理论单位时间流量也较小，因此此时的散热速度相对于理想中的散热速度打了折扣，如果没有及时发现该情况，那么势必会造成散热通道中温度的提升，也就增加了相关器件受热故障的概率，增加了维修成本，因此本申请可以在实际单位时间流量与理论单位时间流量不同的时候，根据两者计算出单位时间流量补偿值，然后基于单位时间流量补偿值计算出第二参数调整量并通过其对散热器进行控制，相当于补偿了因为散热通道的阻力差异所带来的散热速度的偏差，使得温度控制更加精确，进一步地保障了服务器的稳定运行。
