具体实施方式
为了使本发明所解决的技术问题、技术方案及有益效果更加清楚明白,以 下接合附图及实施例,对本发明进行进一步的详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
本申请公开了一种气体冷却装置100,如图1、图2以及图9所示,该气体冷却装置100包括管路结构10,管路结构10限定出气流通道11和液体通道12,气流通道11用于流通高温气体,液体通道12位于气流通道11的外部,且具有与气流通道11连通的喷液部13,管路结构10还具有与气流通道11连通的喷气部14,喷液部13喷出的液体能够在气流通道11内的高温气体以及喷气部14喷出的高压气体的作用下汽化。
首先需要说明的是,以液体通道12内的液体为水作为例子,水的比热容为.J(g·℃),在℃的汽化潜热为.kJ/kg,所以汽化相变时,吸收热能远大于常规水冷方案。
可以理解,本申请实施例所描述的“高温气体”和“高压气体”中的“高温”、“高压”为本领域技术人员通常理解的含义,且并不对气体的温度和压力作具体的数值限制。
可以理解的是,在实际使用过程中,将管路结构10与热炉1的排气管道相连,高温气体进入气流通道11后,由于气流通道11的外部设置有液体通道12,液体通道12能够对高温气体进行冷却。液体通道12内的液体还可以从喷液部13喷向气流通道11,喷出的液体遇到喷气部14喷出的高压气体会迅速雾化,而雾化后的液体会与高温气体混合,雾化后的液体遇高温气体后,迅速汽化,变为蒸气,液体汽化时,则吸收大量热量,从而保证高温气体温度得以迅速下降,高温气体排出管路结构10时就会具有较低的温度。
这里需要补充说明的是,雾化过程以及汽化汽化过程可能并不是严格的先后顺序,喷出的液体可能在高压气体的作用下雾化,然后在高温气体的作用下汽化,也可能直接在高压气体和高温气体的共同作用下直接汽化,在实际工作过程中,液体的相变过程可能是较为复杂的,这里为了方便说明才将雾化过程 和汽化过程分离描述。
相比于现有技术中在排气管道上缠绕冷水管的技术方案,本申请的管路结构10连接于排气管道的出气口,使用方便,且不容易被排气管道烫坏,使用寿命较长;在工作过程中,通过液冷以及液体汽化能够带走大量的热量,实现对高温气体的快速降温,提升了冷却速率和冷却效率;由于设置的喷气部14能够朝向气流通道11喷射高压气体使得喷向气流通道11的液体雾化,能够充分利用喷射的液体进行高温气体降温,降低了喷射液体的用量。
需要额外说明的是,由于气流通道11外部设置液体通道12,液体通道12的存在一方面可以保证管路结构10的外管温度相对安全,外壁温度不可能高于水的沸点温度,另一方面降低管路结构10的内管温度,使得管路结构10的材料可采常规不锈钢管,无需采用特殊耐热材料,降低了气体冷却装置100的制造成本,确保气体冷却装置100的密封特性,避免漏液的现象发生。
可选的,在实际工作过程中,液体通道12和气流通道11均可以为多层,例如,在有的实施例中,管路结构10为三层结构,中间一层为气流通道11,内外两层均为液体通道12其中最外侧和最内侧的液体通道12均能朝向气流通道11内喷射液体,喷气部14设置在管路结构10的最外侧液体通道12的位置,且与液体通道12隔绝设置,以将外部气体喷入气流通道11内。当然,在本申请的其他实施例中,液体通道12和气流通道11的层数还可以根据实际需要选择。
可选的,喷气部14为喷气孔。由此,能够使得喷气部14喷出的气体的压强相对较大,有利于液体雾化。在本实施例中,喷气孔的截面形状可以根据实际需要选择,在此不对喷气孔的截面形状做出限定。
可选的,喷液部13为喷液孔。由此,能够使得喷液部13喷出的液体的流速相对较大,有利于液体雾化。在本实施例中,喷液孔的截面形状可以根据实际需要选择,在此不对喷液孔的截面形状做出限定。
在一些实施例中,如图1所示,气流通道11包括沿气流方向依次排布的高温区111、雾化区112以及汽化区113,液体通道12的部分位于高温区111的外 部,喷气部14及喷液部13均与雾化区112连通。
可以理解的是,高温气体流过高温区111时,能够在液体通道12内的冷却液的作用下进行降温,当高温气体运动到雾化区112时,能够接触到被高压气体雾化的液滴,在汽化区113能够与雾化液体充分接触,使得雾化的液滴迅速汽化实现对高温气体的降温。
在一些具体的实施例中,如图1和图2所示,液体通道12包括冷却通道121和储液腔122,冷却通道121具有进液口1211,进液口1211与外部液源(图未标)相连,且冷却通道121位于高温区111的外部,储液腔122具有连通口1221和喷液部13,连通口1221与冷却通道121相连,且连通口1221的流通面积小于冷却通道121及储液腔122的流通面积。
可以理解的是,高温气体流过高温区111时,能够在冷却通道121内的冷却液的作用下进行降温,这样能够通过换热对高温气体进行降温,有利于提升降温速率。冷却液从冷却通道121内进入储液腔122后再喷射,由于连通口1221的流通面积小于冷却通道121及储液腔122的流通面积,冷却液在进入储液腔122内后能够具有较大的压力,使得通过喷液部13喷向气流通道11的液体具有更高的压力,从而便于雾化。
在一些具体的实施例中,冷却通道121位于管路结构10的上游位置。由此,高温气体能够在管路结构10内先被液体通道12内的冷却液进行冷却,再通过雾化的液体进行冷却,能够较好地提升对高温气体的冷却效果。
在一些具体的实施例中,如图1和图3所示,气体冷却装置100还包括导流管30,导流管30位于冷却通道121内,导流管30用于使冷却通道121内的液体大致充满冷却通道121后在流入储液腔122。由此,有助于确保冷却通道121内始终保持液体充盈,以使高温气体流在入管路结构10内时,能够先被液体通道12内的冷却液进行冷却。
需要说明的是,通过将导流管30设置于冷却通道121内,不仅能够保护导流管30,降低导流管30因撞击发生损坏的风险,还能够使气体冷却装置100的 结构更加紧凑,降低气体冷却装置100整体的占用空间,便于使用。
当然,在其他实施例中,导流管30也可以设置于管路结构10的外壁,本申请对此不做限定,本领技术人员可以根据实际情况选择。
在一些具体的实施例中,导流管30的入口33与冷却通道121连通,且导流管30的入口33位于高温区111远离雾化区112的一端,导流管30的出口与储液腔122连通,以使冷却通道121内的液体沿导流管30流入储液腔122。
在一些具体的实施例中,导流管30包括第一管段31和第二管段32,第一管段31与液体通道12连通,第二管段32与储液腔122连通,第一管段31和第二管段32相连的位置高于气流通道11的进气端114。可以理解的是,导流管30包括第一管段31和第二管段32,方便了将导流管30与液体通道12以及储液腔122相连,而第一管段31和第二管段32相连的位置高于气流通道11的进气端114能够在一定程度上提升第二管段32流入储液腔122中的液体压力,增加液体的总量,从而增加高温气体与液体的接触,加快冷却效率。
值得注意的是,导流管30的最高点(第一管段31和第二管段32相连的位置)高于气流通道11的进气端114,当液体经过管路结构10后,由于导流管30的最高点高于多层管结构的最高点,保证了液体充满多层管结构,并且能够稳定地喷入气流通道11,从而确保冷却效果。
在一些具体的实施例中,冷却通道121的一部分可以充当导流管30的一部分。例如,冷却通道121的一部分作为导流管30的第一管段31。由此,能够减少导流管30的使用,降低制作成本。
在一些具体的实施例中,导流管30为折弯管,折弯管的入口33与液体通道12连通,折弯管的出口与储液腔122连通,且折弯管的折弯处高于气流通道11的进气端114。可以理解的是,导流管30的最高点(折弯处)高于气流通道11的进气端114,当液体经过管路结构10后,由于导流管30的最高点高于气流通道11的进气端114,保证了液体充满液体通道12,并且能够稳定地流入储液腔122,从而确保冷却效果。与此同时,导流管30采用一根直管折弯制造, 方便了导流管30的制造。
在一些更具体的实施例中,如图1所示,冷却通道121具有折弯部(图未标),冷却通道121包括呈夹角设置的第一段1212和第二段1213,第一段1212位于第二段1213的上游,第一段1212与气流通道11的延伸方向相交,第二段1213与气流通道11的延伸方向平行设置。
可以理解的是,在实际工作过程中,高温气体进入气流通道11后,由于第一段1212与气流通道11的延伸方向相交,高温气体能够在第一段1212的导向下进入第二段1213,这样有利于气流通道11内的高温气体与冷却通道121内的冷却液接触,从而利于高温气体的降温。
在一些更具体的实施例中,冷却通道121的进液口1211位于第二段1213的下游。可以理解,进液口1211的设置位置能够确保喷液部13朝向气流通道11喷射液体时,液体具有较大的压力,从而便于液体雾化,以方便高温气体冷却。
在一些实施例中,导流管30的入口33设置于第一段1212上。可以理解的是,导流管30的入口33为补液口,通过将导流管30的入口33设置于第一段1212上,一方面,能够保证冷却液几乎充满冷却通道121后再流入储液腔122内。由此,高温气体能够在冷却通道121被液体通道12内的冷却液进行冷却,配合通过雾化的冷却液进行冷却,能够较好地提升对高温气体的冷却效果。另一方面,能够确保冷却通道121内具有足够的冷却液,有利于高温气体的降温。
在一些具体的实施例中,如图2所示,喷液部13靠近储液腔122的朝向气流通道11设置的侧壁设置。由此,能够使得喷液部13喷出的液体尽可能地靠近气流通道11内的高温气体,从而有利于实现高温气体的降温。
在一些具体的实施例中,管路结构10具有第一管本体(图未标)和第二管本体(图未标),第一管本体形成液体通道12和气流通道11的高温区111和雾化区112。第二管本体形成气流通道11的汽化区113。第一管本体和第二管本体通过法兰连接。
可以理解的是,液体通道12在外,气流通道11的高温区111和雾化区112在内,也就是说管路结构10在第一管本体的位置需要是多层结构,而在第二管本体的位置可以设置为单层管。将管路结构10拆分成第一管本体和第二管本体能够便于管路结构10的制造,方便管路结构10的组装。
在一些具体的实施例中,如图1和图2所示,雾化区112包括渐缩段1121和平直段1122,由此,更有利于喷射的液体在喷射的气体的作用下雾化。
在一些具体的实施例中,雾化区112的渐缩段1121的小端的流通面积大于高温区111的流通面积。由此,高温气体再从高温区111流动到雾化区112会成喷射状气流,这种气流与雾化的液体的接触更加充分,从而有利于高温气体的冷却。
需要补充说明的是,从高温区111到雾化区112再到汽化区113,气体的流通面积逐渐增加,一方面提供了更大的空间给予高温气体散热,另一方面,高温气体呈现出喷射状,有利于与雾化的液体的接触更加充分,从而更有利于高温气体的冷却。
在一些具体的实施例中,雾化区112全部为平直段1122,以确保高温气体匀速流动,减少雾化区112内高温气体出现湍流,降低降温效果的风险。
在一些更具体的实施例中,如图1至图4所示,气体冷却装置100还包括进液管20,进液管20连接于管路结构10且与进液口1211连通。由此,外部冷源的液体可以通过进液管20从进液口1211进入液体通道12,且进液口1211位于第二段1213的下游,使得在整个工作流程中,液体通道12内始终具有充足的液体,有利于朝向气流通道11不断喷射液体。
在另外一些更具体的实施例中,进液管20和与进液管20对接的进液口1211可以位于管路结构10的上游位置,喷液部13位于管路结构10的下游位置。可以理解的是,由于进液管20位于管路结构10的上游位置,使得在整个工作流程中,液体通道12内始终具有充足的液体,高温气体能够在管路结构10内先被液体通道12内的冷却液进行冷却,再通过雾化的液体进行冷却,能够较好地 提升对高温气体的冷却效果。
在一些实施例中,如图1所示,管路结构10包括折弯结构(图未标),折弯结构位于第一段1212和第二段1213的连接处,管路结构10的进气方向与出气方向呈夹角设置。相比于一个直管,本实施例的管路结构10具有折弯结构,能够使得管路结构10在确保气流路径较长的情况下,减小了在某个方向的总长度,从而方便管路结构10的使用。
本申请的实施例对管路结构10的折弯结构的具体形状不作限制。在一种可能的情形下,管路结构10的折弯处可以采用如图1所述的方式以在第一段1212和第二段1213的连接处形成尖角,在另一种可能的情形下,管路结构10的折弯处可以采用圆滑过渡的方式以在第一段1212和第二段1213的连接处形成一定弧度。
在一些具体的实施例中,如图2和图3所示,喷液部13沿气流通道11内的气流流通方向延伸设置,喷气部14倾斜设置,且喷液部13的延伸方向与喷气部14的延伸方向相交。可以理解的是,喷气部14倾斜设置使得喷入气流通道11的气流产生角动惯量,能形成涡流旋风,涡流旋风能够提升高压气体与液体的接触面积,能够提升液体的雾化效率,从而有利于提升高温气体的冷却效率。
在一些具体的实施例中,如图2所示,沿气流通道11内的气体流通方向,储气腔15的流通面积逐渐减小,喷气部14设置在储气腔15朝向气流通道11的倾斜侧壁上。可以理解的是,储气腔15的内壁形成为倾斜侧壁(例如,储气腔15的横截面为三角形,倾斜侧壁为三角形的斜边),能够在一定程度上增加喷入气流通道11的气流产生的角动惯量,使得涡流旋风更加剧烈,能够进一步提升高压气体与液体的接触面积,进一步提升了液体的雾化效率,从而有利于提升高温气体的冷却效率。
在其他实施例中,储气腔15也可以采用其他形状,例如储气腔15的横截面为矩形,只需要保证喷气部14朝向气流通道11设置,并且喷气部14的延伸 方向与喷液部13的延伸方向相交即可,本申请对此不做限定。
在一些具体的实施例中,如图1、图3以及图4所示,气体冷却装置100还包括进气管40,进气管40的一端与储气腔15相连,另一端与外部高压气源相连。由此,能够方便朝向管路结构10供气。
在一些具体的实施例中,喷液部13为多个,且多个喷液部13沿气流通道11的周向间隔分布。可以理解的是,多个喷液部13沿气流通道11的周向间隔分布,能够使得液体被均匀地喷入气流通道11,有利于增大高温气体与液体的接触面积,从而有利于提升冷却速率。
在一些具体的实施例中,喷液部13为多个,且多个喷液部13沿气流通道11的轴向间隔分布。能够使得液体被均匀地喷入气流通道11,有利于增大高温气体与液体的接触面积,从而有利于提升冷却速率。
需要说明的是,在实际设计中,喷液部13可以设置沿气流通道11的方式设置多圈,每一圈均设有沿气流通道11的周向间隔分布的多个喷液部13。喷液部13的分布可以根据实际需要选择。
在一些具体的实施例中,喷液部13的尺寸小于mm。由此,从喷液部13喷出的液体具有较高的压力,有利于液体在高压气体的作用下雾化。这里需要补充说明的是,喷液部13的形状以及尺寸可以根据实际需要做出选择,并不限于上述限定。
在一些具体的实施例中,喷液部13形成为狭长孔型孔。这样能够进一步提升喷液部13喷出的液体的压力,有利于液体在高压气体的作用下雾化。
在一些具体的实施例中,如图4所示,喷气部14为多个,且多个喷气部14沿气流通道11的周向间隔分布。可以理解的是,多个喷气部14沿气流通道11的周向间隔分布,能够使得高压气体被均匀地喷入气流通道11,有利于增大高压气体与液体的接触面积,方便喷射进入气流通道11的液体雾化,从而有利于提升冷却速率。
在一些具体的实施例中,喷气部14为多个,且多个喷气部14沿气流通道 11的轴向间隔分布。能够使得高压气体被均匀地喷入气流通道11,有利于增大高压气体与液体的接触面积,方便喷射进入气流通道11的液体雾化,从而有利于提升冷却速率。
需要说明的是,在实际设计中,喷气部14可以设置沿气流通道11的方式设置多圈,每一圈均设有沿气流通道11的周向间隔分布的多个喷气部14。喷气部14的分布可以根据实际需要选择。

这里需要补充说明的是,在本申请的实施例中,喷气部14和喷液部13的分布形式可以根据实际需要任意组合,例如在有的实施例中,喷气部14为多圈,喷液部13也为多圈;又例如,在有的实施例中,喷气部14和喷液部13均为一圈。
在本申请的实施例还提供一种气体冷却装置100,如图5至图8所示,该气体冷却装置100包括管路结构10,管路结构10限定出气流通道11和液体通道12,气流通道11用于流通高温气体,液体通道12位于气流通道11的外部,且具有与气流通道11连通的喷液部13,喷液部13用于朝向气流通道11喷液。
具体来说,气流通道11具有进气端114和出气端115,进气端114用于引入高温气体,液体通道12具有进液口1211。液体通道12还包括连接管50,连接管50的出口设置在出气端115,连接管50的入口33与液体通道12连通,连接管50的出口与气流通道11连通以朝向气流通道11喷液。其中,喷液部13设置在连接管50的出口,连接管50的出口通过喷液部13朝向气流通道11喷液。
可以理解的是,本实施例的气体冷却装置100,液体从连接管50的出口喷向气流通道11时,在遇到高温的气体后,大部分的液体会迅速汽化,而在汽化 过程中会吸收大量的热,这样高温气体所带的热量就会在液体汽化过程中被大量消耗,快速地实现了高温气体的冷却,相比于现有技术水冷换热的降温方式,本实施例利用液体由液相变气相时需吸收大量热量的原理,让高温气体得以快速冷却,提升了冷却效果和冷却效率。
此外,液体通道12的存在一方面可以保证管路结构10的外管温度相对安全,外壁温度不可能高于水的沸点温度,另一方面降低管路结构10的内管温度,使得管路结构10的材料可采常规不锈钢管,无需采用特殊耐热材料,降低了管路结构10的制造成本,确保管路结构10的密封特性,避免漏液的现象发生。
需要额外说明的是,在本申请中,连接管50可以仅有一个,也可以为多个,当连接管50为多个时,多个连接管50既可以沿管路结构10的轴向间隔分布,多个连接管50也可以沿管路结构10的周向间隔分布,多个连接管50还可以沿管路结构10的轴向布置多圈,每一圈均包括沿管路结构10的周向间隔分布的连接管50。由此,在实际使用过程中,连接管50的排布可以根据实际需要选择,只需要保证具有较好的冷却效果即可。
在一些具体的实施例中,气流通道11倾斜设置,且进气端114高于出气端115。可以理解的是,气流通道11倾斜设置能够使得位于气流通道11外侧的液体通道12也是倾斜设置,进气端114高于出气端115能够避免液体通道12内的液体出现倒流现象。
在一些具体的实施例中,如图5至图8所示,连接管50包括第一管体51和第二管体52,第一管体51与液体通道12连通,第二管体52与气流通道11连通,第一管体51和第二管体52相连的位置高于气流通道11的进气端114。
可以理解的是,连接管50包括第一管体51和第二管体52,方便了将连接管50与储液腔122以及气体通道相连,而第一管体51和第二管体52相连的位置高于气流通道11的进气端114能够在一定程度上提升第二管体52喷出的液体压力,增加液体的总量,从而增加高温气体与液体的接触,加快冷却效率。
在一些实施例中,连接管50还包括第三管体53,第三管体53的两端分别 与第一管体51和第二管体52相连,第三管体53高于气流通道11的进气端114。可以理解的是,连接管50的最高点(第三管体53的位置)高于管路结构10的最高点(进气端114),当液体经过管路结构10后,由于U形管的最高点高于管路结构10的最高点,保证了液体充满管路结构10,并且能够稳定地喷入气流通道11,从而确保冷却效果。
在一些具体的实施例中,如图5所示,第三管体53水平设置,且第一管体51和第二管体52均垂直于第三管体53。由此,保证了液体充满多层管结构,并且能够稳定地喷入气流通道11,从而确保冷却效果。当然,在本申请的其他实施例中,第一管体51、第三管体53和第二管体52的夹角可以根据实际需要选择,并不限于本实施例的限定。
在一些具体的实施例中,连接管50为折弯管,折弯管的入口33与液体通道12连通,折弯管的出口与气流通道11连通,且折弯管的折弯处高于气流通道11的进气端114。可以理解的是,连接管50的最高点(折弯处)高于管路结构10的最高点(进气端114),当液体经过管路结构10后,由于连接管50的最高点高于管路结构10的最高点,保证了液体充满管路结构10,并且能够稳定地喷入气流通道11,从而确保冷却效果。与此同时,连接管50采用一根直管折弯制造,方便了连接管50的制造。
在其他实施例中,连接管50为一个直管,直管的入口33与液体通道12连通,直管的出口与气流通道11连通,也就是说,在本申请的实施例中,连接管50并不限于前文所述的U型管结构。
在一些实施例中,气体通道11包括高温区(图未标),高温区位于气体通道11靠近高温气体流入方向的一端。液体通道12还可以包括冷却通道(图未标)和储液腔(图未标),进液口1211设置于冷却通道,进液口1211与外部液源相连,且冷却通道位于高温区的外部。储液腔具有连通口和喷液部13,连通口与冷却通道连通,连通口的流通面积小于冷却通道及储液腔的流通面积。示例性地,储液腔的连通口与连接管50连通,以通过连接管50从冷却通道获取 冷却液。
可以理解的是,高温气体流过高温区时,能够在冷却通道内的冷却液的作用下进行降温,这样能够通过换热对高温气体进行降温,有利于提升降温速率。冷却液从冷却通道内进入储液腔后再喷射,由于连通口的流通面积小于冷却通道及储液腔的流通面积,冷却液在进入储液腔内后能够具有较大的压力,使得通过喷液部13喷向气流通道11的液体具有更高的压力。
在一些具体的实施例中,喷液部13为多个,且多个喷液部13沿气流通道11的周向间隔分布。可以理解的是,多个喷液部13沿气流通道11的周向间隔分布,能够使得液体被均匀地喷入气流通道11,有利于增大高温气体与液体的接触面积,从而有利于提升冷却速率。
在一些具体的实施例中,如图1和图5所示,气体冷却装置100还包括风机60,风机60连接于气流通道11的出气端115,风机60用于驱动气流通道11气流通道11内的气体强制流动。可以理解的是,风机60能够驱动气流通道11气流通道11内的气体流动,从而提升气流通道11气流通道11内的气流流速,有利于提升冷却效率。
在一些具体的实施例中,如图1和图5所示,气体冷却装置100还包括抽气管70,抽气管70的一端与气流通道11气流通道11的出气端115相连,另一端用于安装风机60,抽气管70安装风机60的一端低于与气流通道11的出气端115相连的一端。可以理解的是,风机60与气流通道11的出气端115通过抽气管70相连,能够保证气流到风机60位置时已经处于较低的温度,从而避免气流温度相对较高导致对风机60的腐蚀现象,有利于延长风机60的使用寿命。
在一些更具体的实施例中,如图1和图5所示,气体冷却装置100还包括排气管,排气管连接于风机60背离抽气管70的一侧。可以理解的是,增设的排气管能够朝向指定位置排气,当高温气体中存在有害气体时,能够将有害气体排放至指定空间内,提升了工作安全性。
本申请的实施例还提供一种热炉1,如图9所示,热炉1包括炉体200和上 述的气体冷却装置100,炉体200具有排气管80,气体冷却装置100用于冷却炉体200通过排气管80释放的气体。可以理解的是,在实际使用过程中,将管路结构10与热炉1的排气管80相连,高温气体进入气流通道11后,由于气流通道11的外部设置有液体通道12,液体通道12能够对高温气体进行冷却。液体通道12内的液体还可以从喷液部13喷向气流通道11,喷出的液体遇到喷气部14喷出的高压气体会迅速雾化,而雾化后的液体会与高温气体混合,雾化后的液体遇高温气体后,迅速汽化,变为蒸气,液体汽化时,则吸收大量热量,从而保证高温气体温度得以迅速下降,高温气体排出管路结构10时就会具有较低的温度。
相比于现有技术中在排气管道上缠绕冷水管的技术方案,本申请的管路结构10连接于排气管道(例如排气管80)的出气口,使用方便,且不容易被排气管道烫坏,使用寿命较长;在工作过程中,通过液冷以及液体汽化能够带走大量的热量,实现对高温气体的快速降温,提升了冷却速率和冷却效率;由于设置的喷气部14能够朝向气流通道11喷射高压气体使得喷向气流通道11的液体雾化,能够充分利用喷射的液体进行高温气体降温,降低了喷射液体的用量。
需要额外说明的是,由于气流通道11外部设置液体通道12,液体通道12的存在一方面可以保证管路结构10的外管温度相对安全,外壁温度不可能高于水的沸点温度,另一方面降低管路结构10的内管温度,使得管路结构10的材料可采常规不锈钢管,无需采用特殊耐热材料,降低了气体冷却装置100的制造成本,确保气体冷却装置100的密封特性,避免漏液的现象发生。
以上所述仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本发明的保护范围之内。
