Description

风扇组合
技术领域
本发明涉及一种风扇组合。
背景技术
一般的电子设备的发热部件在运行的过程中都会产生热量，若不将这些热量及时排出，热量就会越积越多，最终导致电子设备无法运行甚至损毁。现有技术中，通常通过在发热部件上装设风扇的方式将其产生的热量排出。
目前风扇的转速大多根据发热部件的温度的高低来调节，因此风扇的转速是随发热部件的温度不断变化的，研发人员进行风扇的噪音测试时，往往需要实时获得风扇的转速进而对风扇的噪音或其它指标进行分析、设计等。但目前要实时获得风扇的转速则比较困难。
发明内容
鉴于以上内容，有必要提供一种易于实时获得风扇转速的风扇组合。
一种风扇组合，包括一传感器、一显示装置及一风扇，所述显示装置包括一显示屏、一放大器及一单片机，所述传感器设置于所述风扇的外壳上并通过所述放大器与所述单片机相连，所述单片机还与所述显示屏相连，所述传感器用于感测所述风扇的转速，并将感测到的转速信号传送给所述放大器，所述放大器用于接收所述传感器感测到的所述风扇的转速信号，并对所述转速信号进行放大整形后传送到所述单片机，所述单片机根据所述放大器传送的放大整形后的转速信号计算出所述风扇的转速并将所述风扇的转速转化为数字信号后传送到所述显示屏上进行显示。
本发明风扇组合通过设置于所述风扇的外壳上的传感器感测所述风扇的转速，并通过所述放大器对所述传感器感测到的所述风扇的转速信号进行放大整形后传送到所述单片机，所述单片机根据放大整形后的转速信号计算出所述风扇的转速并将所述风扇的转速转化为数字信号后传送到所述显示屏上进行显示，以方便用户实时获得风扇转速并进行分析、设计。
附图说明
图1是本发明风扇组合的较佳实施方式的立体分解图。
图2是图1的立体组合图。
图3是图1中的显示装置与传感器相连的模块图。
具体实施方式
请共同参考图1至图3，本发明风扇组合8可实时获得一风扇9的转速，其较佳实施方式包括一传感器20、一显示装置40及所述风扇9。所述风扇9包括一外壳10及一转动装设于所述外壳10内的叶轮30。
所述风扇9的外壳10包括相对设置的一上壳102、一下壳106及连接所述上壳102及下壳106的一圆形立壁104。所述上壳102及下壳106的同侧各开设固定孔112用于装设所述显示装置40，所述上壳102的上表面开设一进风口108，所述下壳106的下表面开设一出风口110。所述叶轮30包括一圆形轮毂302及围绕所述轮毂302外圆周而设的若干叶片304。所述叶轮30转动时，由所述叶片304将外部的空气通过所述进风口108吸入所述外壳10内，而后并借助所述叶片304由所述出风口110排出。
所述传感器20设置于所述轮毂302上，其与所述显示装置40相连，用以感测所述风扇9的转速，并将感测到的转速信号传送给所述显示装置40。所述传感器20可以采用红外光电传感器或其它磁感式传感器等。所述传感器20可以采用如下方式感测风扇9的转速：例如风扇9转动一周，则所述传感器20可触发一个高电平(如5V)或低电平(如0V)的电脉冲信号。
所述显示装置40包括大致呈长方体的本体402、一显示屏404、设置于本体402内部的一放大器408及一单片机410。所述本体402上开设卡固孔406，用于通过旋入螺钉50将显示装置40固定到风扇9的外壳10上。所述显示屏404设置于所述本体402上，用于实时将风扇9的转速显示给用户。所述传感器20通过所述放大器408与所述单片机410相连，所述单片机410还与所述显示屏404相连。所述放大器408用于接收传感器20感测到的风扇9的转速信号，并根据实际信号的衰减、干扰等影响对所述转速信号进行放大整形后传送到所述单片机410，所述单片机410根据所述放大器408传送的放大整形后的转速信号计算出风扇9的转速并将所述风扇9的转速转化为数字信号后传送到所述显示屏404上进行显示。在其它实施方式中，所述显示装置40也可以设置于装设所述风扇9的一电子设备上以便于用户分析风扇9的转速。
使用时，将所述显示装置40的卡固孔406对准所述风扇9的固定孔112，再将螺钉50穿过所述显示装置40的卡固孔406锁入所述风扇9的固定孔112，使所述显示装置40固定于所述风扇9上并与所述风扇9合为一体。当所述风扇9开始工作时，叶轮30转动，由所述叶片304将外部的空气通过所述进风口108吸入所述外壳10内，而后借助所述叶片304由所述出风口110排出风流，传感器20就将感测到的风扇9的转速信号实时传送给所述显示装置40的放大器408，放大器408将接收的转速信号进行放大整形后传送到所述单片机410，所述单片机410根据所述放大器408传送的放大整形后的转速信号计算出风扇9的转速并将所述风扇9的转速转化为数字信号后传送到所述显示屏404上进行显示，以供用户观察、分析、设计等。
本发明风扇组合8的结构简单且可以实时获得风扇9的转速，并传送到所述显示屏404上进行显示，方便用户分析、设计等。
