空调器即空气调节器，是指利用人工手段对建筑物内环境空气的温度、湿度、流速等参数进行调节和控制的设备。一般包括冷源/热源设备，冷热介质输配系统，末端装置等 几大部分和其他辅助设备。主要包括，制冷主机、水泵、风机和管路系统。末端装置则负责利用输配来的冷、热量，具体处理空气状态，使目标环境的空气参数达到设定目标。
相关技术中，大部分空调器采用压缩机作为冷媒的动力源。压缩机是一种将低压气体提升为高压气体的流体机械。压缩机从吸气管吸入低温低压的冷媒气体，通过对冷媒气体进行压缩，输出高温高压的冷媒气体，而且为冷媒的循环提供动力，从而实现压缩→冷凝(放热)→膨胀→蒸发(吸热)的制冷循环。
为了避免压缩机的运行温度超限，导致压缩机出现泵体磨损、电机退磁等失效状况，通常空调器的电控系统依据温度数据对压缩机进行控制，而温度数据来自设在压缩机外壁的温度传感器。但是，温度传感器的安装结构不牢固，温度传感器容易出现松动，导致测温的数据失真，不利于保护压缩机。
如图1至图4所示，本公开第一方面的实施例提出一种应用于压缩机的壳体组件，压缩机通常具有封闭式的壳体100，电机和压缩机构均设置在壳体100的内部，压缩机的排气管110设置在壳体100上，通过排气管110将压缩后的高温高压的冷媒气体排出。
可以理解的是，为了准确检测壳体100的温度以监控压缩机的运行状态，在壳体100的外壁设置有温度传感器200。如图8所示，温度传感器200为柱形，温度传感器200需要紧贴在壳体100的外壁上，紧密接触以准确测量壳体100的温度，因此壳体100上连接有固定支架300以限定温度传感器200。
如图2所示，固定支架300包括有罩住温度传感器200的固定部310和连接部320，连接部320用于固定连接壳体100，连接部320为两个，两个连接部320位于固定部310的两侧，使得固定部310与壳体100之间的相对位置固定。
固定部310包括顶板311和两个侧板312，两个侧板312分布在顶板311的两侧，也即侧板312作为顶板311和连接部320之间的连接结构，两个侧板312为倾斜布置，侧板312与顶板311之间为钝角，可以理解的是，顶板311和两个侧板312类似梯形的三个侧边，顶板311、两个侧板312以及壳体100围成的安装腔301大致呈梯形。
此外，参照图3和图4，顶板311设置有开口槽3112，开口槽3112位于背离入口端的一端，开口槽3112的开槽也是朝背离入口端的方向，而且偏离顶板311的中心线，也即开口槽3112位于顶板311的边缘位置。通过设置开口槽3112，顶板311的弹性增大，通过弹性变形的复位力，顶板311对温度传感器200施加压力。开口槽3112不在顶板311的中心线上，顶板311的变形偏置到开口槽3112的边缘，而顶板311与温度传感器200接触的位置变形较小，有利于对温度传感器200施加更稳定的压力，在压缩机运行中，减少了温度传感器200松动的风险。
装配时，将温度传感器200插入安装腔301，温度传感器200同时接触顶板311、两个侧板312以及壳体100，两个侧板312与温度传感器200接触的位置高于温度传感器200的轴线。如图2所示，固定部310的顶板311和两个侧板312均对温度传感器200施加压力，顶板311施加的力F1朝向壳体100，使得温度传感器200紧贴在壳体100的外壁，而两个侧板312施加的力F2是对称的，两个力F2的合力也是朝向壳体100，同样是使得温度传感器200紧贴在壳体100的外壁。开口槽3112为顶板311提供弹性变形，利用弹性变形的复位力作用于温度传感器200，通过顶板311和两个侧板312对温度传感器200的限制，使得温度传感器200与壳体100保持紧密接触，温度传感器200能够有效、准确地检测壳体100的温度，测量数据准确可靠。本公开实施例的固定支架300消除了温度传感器200松动的缺陷，温度传感器200能够实时反馈壳体100的温度，有利于准确控制压缩机的运行，防止压缩机出现运行温度超限，避免出现泵体磨损、电机退磁等失效状况。
可以理解的是，如图1所示，由于排气管110用于排出高温高压的冷媒气体，排气管110所在位置温度较高，将温度传感器200与壳体100的连接处布置在靠近排气管110的位置，能够检测更为准确的数据，有助于保护压缩机。
可以理解的是，固定部310具有弹性能够对温度传感器200进行定位，可以是固定部310采用弹性材料，比如铜合金，也可以是固定部310具有可以弹性形变的结构，能够满足固定部310限定温度传感器200即可。
参照图3，可以理解的是，以温度传感器200的轴向为顶板311的长度方向，垂直于长度方向即为宽度方向，为了促使开口槽3112偏离温度传感器200，将开口槽3112的宽度尺寸设定为顶板311的宽度尺寸一半以下，其中以开口槽3112的宽度尺寸为五分之一顶板311的宽度尺寸为较佳方案，顶板311保留较大面积，有利于对温度传感器200施加压力。
参照图3，可以理解的是，开口槽3112与扩口313之间预留有间距，使得固定部310至少有一部分是完整的，该部分完整的顶板311和两个侧板312对温度传感器200施加压力，有利于固定温度传感器200。
可以理解的是，固定支架300上温度传感器200装入的一端定义为入口端，温度传感器200从入口端插入安装腔301，通常入口端具有较大的截面积以便于温度传感器200装入。参照图5和图6，为了提供充足的限定，可以在入口端的顶板311上设置弧形拱起3111，如图6所示，弧形拱起3111为弧形的凸起结构，并且弧形拱起3111朝向安装腔301，当温度传感器200装入安装腔301，弧形拱起3111抵接于温度传感器200。可以理解的是，弧形拱起3111的结构具有弹性，在接触温度传感器200时产生微小的弹性变形，根据反 作用力原理，弧形拱起3111对温度传感器200施加有朝向壳体100的力，促使温度传感器200紧贴在壳体100的外壁。
可以理解的是，弧形拱起3111可以是仅设置在入口端，或者弧形拱起3111沿着温度传感器200的轴向延伸，又或者沿温度传感器200的轴向，顶板311上设置有多个弧形拱起3111，均能够满足限定温度传感器200的要求。
可以理解的是，可以将安装腔301设置为逐步收缩的锥形，也就是在温度传感器200的轴向上，安装腔301是逐渐收缩，入口端位于较大的一端，以便于温度传感器200装入。可以将安装腔301的大端尺寸设为大于温度传感器200，而且安装腔301的小端尺寸设为小于温度传感器200，考虑到顶板311和两个侧板312类似梯形的三个侧边，安装腔301的截面类似梯形，因而可以是安装腔301的小端宽度小于温度传感器200的直径，或者是安装腔301的小端高度小于温度传感器200的直径，还可以是安装腔301的小端宽度和高度均小于温度传感器200的直径，开口槽3112给固定部310提供了弹性形变，能够限定温度传感器200。当温度传感器200装入安装腔301，利用逐渐收缩的安装腔301限定温度传感器200，并且固定部310对温度传感器200施加压力，使得温度传感器200紧贴壳体100的外壁，使得温度传感器200与壳体100紧密贴合，实时准确测量壳体100的温度。而且安装腔301的小端能够防止温度传感器200穿过，帮助准确定位。
可以理解的是，也可以将安装腔301的小端设置为匹配温度传感器200的截面积，温度传感器200可以完全置于安装腔301内，也可以是一部分的温度传感器200穿出到安装腔301外，利用固定部310限定温度传感器200，使得温度传感器200保持抵接壳体100，实时、准确地检测壳体100的温度。
可以理解的是，还可以将安装腔301的小端设置为略大于温度传感器200，温度传感器200的一部分穿出到安装腔301外。
可以理解的是，实现安装腔301逐渐收缩所采用的结构是顶板311为倾斜布置，在温度传感器200的轴向上，沿背离入口端的方向，顶板311向壳体100倾斜，也即是顶板311与壳体100之间的距离逐渐减小，使得安装腔301呈现逐渐收缩的结构。此外，倾斜的顶板311对温度传感器200施加有朝向壳体100的力，促使温度传感器200紧贴在壳体100的外壁。
可以理解的是，实现安装腔301逐渐收缩所采用的结构是两个侧板312逐渐收拢，在温度传感器200的轴向上，沿背离入口端的方向，两个侧板312之间的距离逐渐减小，使得安装腔301呈现逐渐收缩的结构。此外，采用了上述结构，两个侧板312对温度传感器200施加力更大，有助于促使温度传感器200紧贴在壳体100的外壁，而且两个侧板312 还配合夹紧温度传感器200，防止温度传感器200从安装腔301中脱出。
当然，还可以同时采用顶板311为倾斜布置和两个侧板312逐渐收拢的结构，以实现安装腔301逐渐收缩。当温度传感器200装入安装腔301，顶板311和两个侧板312均对温度传感器200施加压力，使得温度传感器200紧贴在壳体100的外壁，而且两个侧板312还配合夹紧温度传感器200，防止温度传感器200从安装腔301中脱出。
参照图3，可以理解的是，固定支架300设置有扩口313，扩口313的横截面大于温度传感器200的横截面，扩口313即为入口端，作为安装腔301的入口，也即温度传感器200从扩口313装入安装腔301。采用扩口313扩大进入的空间，便于安装温度传感器200，而且扩口313的内壁面为喇叭形，可以促使温度传感器200对中，准确进入安装腔301，提高安装效率。
可以理解的是，考虑到固定支架300用于固定温度传感器200，而固定部310需要对温度传感器200施加压力，促使温度传感器200接触壳体100的外壁，设定在温度传感器200的轴线方向上，扩口313占据的长度应当小于固定支架300的三分之一，其中扩口313的长度为固定支架300的十分之一是较佳选择，固定部310具有十分之九的长度对温度传感器200施加压力，足够限定温度传感器200。
可以理解的是，温度传感器200的有效感温区域沿轴向的长度为有效感温长度，有效感温长度是固定的，将固定部310的长度设为小于有效感温长度，有利于观察温度传感器200与壳体100是否紧密接触，而且减少组装过程中的阻力。
参照图8，可以理解的是，温度传感器200通常在外部安装有一个热敏套管210，考虑到温度传感器200装入安装腔301的位置需要准确定位，将扩口313的横截面设置为小于热敏套管210的横截面，也即热敏套管210不能进入扩口313，起到限位的作用。在装配温度传感器200时，利用热敏套管210抵接扩口313作为定位，准确限定温度传感器200的装入深度。
可以理解的是，为了实现限定温度传感器200装入安装腔301的长度还可以采用其他的结构形式，比如将固定支架300上相对扩口313的一端设置为封闭的结构，温度传感器200装入安装腔301时直接插到底即可，简单便捷。
或者，在固定部310的内壁设置限位环之类的限位结构，温度传感器200装入安装腔301，直至温度传感器200抵接限位环。
又或者，在侧板312上背离扩口313的一端设置压片314，压片314沿温度传感器200的轴向延伸，当温度传感器200装入安装腔301，通过观察温度传感器200与压片314的相对位置可判断温度传感器200是否装入到位，两个压片314也可以对温度传感器200施 加夹持力，固定温度传感器200，防止从安装腔301脱出。
参照图3，可以理解的是，在每个连接部320上布置有两个焊点321，固定支架300共有四个焊点321，焊点321用于配合壳体100进行焊接，焊接方式为电阻焊，以将连接部320固定在壳体100的外壁上。电阻焊是指利用电流通过焊件及接触处产生的电阻热作为热源将焊件局部加热，在工件接触面及邻近区域将工件加热到熔化或塑性状态，同时加压进行焊接的方法。焊接时，不需要填充金属，生产率高，焊件变形小，容易实现自动化。为了准确限定焊接的区域，在每个连接部320上布置两个焊点321，如图4所示，焊点321为朝向壳体100的凸包，配合电阻焊工艺，提高焊接效率。
可以理解的是，连接部320也可以通过固定件安装在壳体100，比如连接部320通过螺丝固定连接壳体100。连接部320还可以通过胶水黏贴于壳体100，实现固定。
本公开第二方面实施例提出的压缩机，包含第一方面实施例的壳体组件，在压缩机的壳体100上连接固定支架300，固定支架300的固定部310包括顶板311和两个侧板312，两个侧板312分布在顶板311的两侧，两个侧板312为倾斜布置，侧板312与顶板311之间为钝角，可以理解的是，顶板311和两个侧板312类似梯形的三个侧边，使得顶板311、两个侧板312以及壳体100围成的安装腔301截面呈梯形。
装配时，将温度传感器200插入安装腔301，温度传感器200同时接触顶板311、两个侧板312以及壳体100，两个侧板312与温度传感器200接触的位置高于温度传感器200的轴线。如图2所示，固定部310的顶板311和两个侧板312均对温度传感器200施加压力，顶板311施加的力F1朝向壳体100，使得温度传感器200紧贴在壳体100的外壁，而两个侧板312施加的力F2是对称的，两个力F2的合力也是朝向壳体100，同样是使得温度传感器200紧贴在壳体100的外壁。开口槽3112为顶板311提供弹性变形，利用弹性变形的复位力作用于温度传感器200，通过顶板311和两个侧板312对温度传感器200的限制，使得温度传感器200与壳体100保持紧密接触，温度传感器200能够有效测量壳体100的温度，测量数据准确可靠。本公开实施例的固定支架300消除了温度传感器200松动的缺陷，保证温度传感器200准确地检测出壳体100的温度，温度传感器200能够实时反馈壳体100的温度，有利于准确控制压缩机的运行，防止压缩机出现运行温度超限，避免出现泵体磨损、电机退磁等失效状况。

上面结合附图对本公开实施例作了详细说明，但是本公开不限于上述实施例，在所属技术领域普通技术人员所具备的知识范围内，还可以在不脱离本公开宗旨的前提下，作出 各种变化。
