具体实施方式
本发明提供一种具有导流散热功能的干体温度校验仪，先参见图1A和图1B，其包括有仪器的外壳6和置于该外壳6内的炉体1，还可以包括装配于外壳6内与炉体1平行的控制板2；外壳6设有插孔61与炉体1的炉口15相对，插孔61用于插入被测装置9。
结合图2和图3所示，炉体1包括均热块、恒温块13、置于恒温块13外围的隔热层14。炉体1的下方设置有炉体底座11，恒温块13和隔热层14置于炉体底座11上。炉体底座11下部空腔内装配有冷却风扇16。恒温块13包围均热块(炉芯)，均热块的上端具有容纳被测装置9的开口即炉口15，恒温块13内还包括与均热块热接触的热源；隔热层14围绕所述恒温块13设置，隔热层14和恒温块13之间间隔一定距离以形成炉体内部的散热通道C1，需要给炉体1降温时，炉体1底部的冷却风扇16工作使炉芯产生的热量通过该散热通道C1从炉体1上方排气孔排出(炉体内部气流参见图3细箭头所示)。
本发明中，在所述炉体1的外围隔热层14和外壳6之间设置有用于对仪器进行导流散热且能产生定向气流的气流产生装置。所述气流产生装置位于外壳6内且位于炉体1的外部。
气流产生装置的个数不限，可以根据实际需要布置，其设置的位置应当使得气流产生装置产生的气流能够作用于被测装置9的手柄91而使手柄91及位于手柄91内的传感器被降温。可以理解地，单个气流产生装置可以设置在所述炉体1的一侧，或者多个气流产生装置设置在所述炉体1的外围，进一步地，多个气流产生装置可以等间距设置；当炉体1为长方体时，气流产生装置可以邻近炉体1的一个或多个侧面设置。
其一，气流产生装置的一种实施方式为与气源连通的气体通道C2。如图3所示，所述气体通道为一个或多个，设置在炉体1外围。气体通道C2的形式不限，只要能够起到将气源的气流引导至被测装置9的手柄即可。可以理解地，所述气源可以为炉体底部的冷却风扇16，还可以为炉体外部的自然气流或者其它气源。
进一步地，该气体通道C2底端具有进气口，其与气源连通使得气流进入气流通道C2。该气体通道C2的顶端设有出气口使得气流通过该出气口流向被测装置9的手柄91。具体地，气体通道C2可以为四块矩形板围成的长方体筒，也可以是圆筒或者长导管。当气体通道C2为多个时，可以互相连通，且所有气体通道C2的出气口中的每一个均朝向被测装置9的手柄91，所有气体通道也可以仅设一个出气口且朝向被测装置9的手柄91。
在一个实施例中，参见图3所示，气体通道C2是由控制板2和控制板支架22围成的竖直长方体通道，所述控制板支架22为三块矩形长板围成的矩形凹槽结构，其侧面开口被控制板2部分封闭，上、下两端开口未封闭。该气体通道C2将位于炉体下方的冷却风扇16产生的气流从炉体下方引导至被测装置9的手柄91处，可以理解地，冷却风扇16位于炉体底座11的空腔内，炉体底座11与气体通道C2邻近的侧壁上设有多个通气孔以使得冷却风扇16产生的气流经气体通道C2底端的进气口进入气体通道C2，例如，如图3所示，在炉体1底部和炉体底座11之间形成气体通道C3，如此，冷却风扇16所在炉体1底部腔体与炉体1外侧的气体通道C2通过气体通道C3连通，冷却风扇16产生的气流通过气体通道C3和气体通道C2排出仪器外壳6并能被引导至被测装置9的手柄91处。
其二，气流产生装置的另一种实施方式是位于炉体一侧或多侧的导流风扇21、气泵、和鼓风机中的一种或几种的组合。
在一个实施例中，气流产生装置为设置在炉体一侧的导流风扇21、气泵或鼓风机。可以理解地，可以有多个导流风扇21分别设置在炉体的多个侧面，共同产生气流使得被测装置9的手柄91降温。所述气流产生装置设置在位于炉体一侧的安装架或者安装板上。通过改变所述安装架的高度或者安装板的位置，从而调节所述气流产生装置的高度。具体地，结合图5和图1A所示，安装板23位于控制板支架22的上方，且该控制板支架22的高度要低于炉体高度，使得安装在安装板23上的所述导流风扇21位于炉体的一侧且略低于炉体的高度而在外壳6内形成利于导流风扇21工作的空间，因此导流风扇21所产生的气流可以作用于被测装置9的手柄91而起到降温的作用。
其三，气流产生装置的又一种实施方式是位于炉体一侧的导流风扇21、气泵、和鼓风机中的一种或几种与气流通道C2的组合。可以在气流通道C2的顶部、中间或者下部设置有安装板以安装导流风扇21、气泵、和鼓风机。在本实施例中，结合图3和图4所示，气体通道C2是由控制板2和控制板支架22围成的竖直长方体风道，所述控制板支架22为三块矩形板围成矩形凹槽结构，其侧面开口被控制板2部分封闭形成气体通道C2，气体通道C2的顶端开口处被风扇安装板封闭，导流风扇21安装在风扇安装板的下方，风扇安装板与导流风扇21相对应的位置设有开口以允许导流风扇21和气体通道C2产生的气流通过。气体通道C2的底端进气口与冷却风扇16产生的气流连通。冷却风扇16位于炉体底座11的空腔里，炉体底座11和与气体通道C2邻近的设有通气孔的侧壁形成气体通道C3，冷却风扇16产生的气流依次经气体通道C3、气体通道C2的进气口、风扇安装板的开口处排出外壳6。
当所述气流产生装置为导流风扇21时，所述导流风扇21可以平放在炉体1一侧，也可以倾斜一定角度，使得导流风扇21产生的气流更容易地流向炉体1。优选地，所述导流风扇21向炉体1侧面的倾斜角度为0度至90度之间，如此使得导流风扇21的扇面更多地面对所述炉体1。
可以理解，以上气流产生装置可以用气泵和鼓风机替换导流风扇21；还可以根据实际需要调节所述导流风扇21的转速、气泵和鼓风机的工作功率以产生不同的气量实现对被测装置9手柄不同的降温效果。
可以理解地，外壳6的下方还设置有壳体底座5，壳体底座5和外壳6上下配合形成可拆卸的外壳结构，从而便于干体温度校验仪内部元件的维修与更换，壳体底座5的下方设有通风口，以允许外界的气体或气源进入干体温度校验仪内部。本发明的干体温度校验仪还包括设置在外壳6内部的测量板模块4和系统板模块3，所述测量板模块4用于连接测量线以实现干体温度校验仪的电测功能，系统板模块3用于参数设置，数据显示以实现人机交互。
本发明提供的导流散热干体温度校验仪的工作原理为：气流产生装置产生的气流会流向其四周，因此会有部分气流向被测装置手柄方向流动，该部分气流的温度为常温，使得被测装置手柄靠近炉芯(均热块)口端的高温降低，还使得被测装置手柄附近的热气流被气流产生装置产生的气流吹离炉体，从而降低了被测装置手柄处的温度。
实施效果：
将气流产生装置应用于高温干体温度校验仪时，如图1B所示通过导流风扇21和气流通道共同作用，当导流风扇的转速为6000转/分时，被测装置的手柄温度由133度降低至61度，当风扇转速为8000转/分时，手柄温度进一步降低至48度。
在具体实施时，本发明提出的气流产生装置适用于任何一种已有的或未来新开发的各种温度校验仪、炉体等，本领域技术人员依据本发明结合具体炉体或温度校验仪的形式可以做多种变化，这些变化也属于本发明公开的内容。
