Description

取暖器
本申请要求于2017年9月18日提交中国专利局、申请号为201710842594.4、发明创造名称为“取暖器”和于2017年9月18日提交中国专利局、申请号为201721194555.X、发明创造名称为“取暖器”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及家用电器领域，更具体而言，涉及一种取暖器。
背景技术
取暖器例如油汀取暖器的工作原理是用热源(例如加热棒)加热内部导热油形成循环流动的热油，油路布置于散热片上，当热油在油路中流动时把热量传递给散热片，经由散热片传递给空气从而达到取暖效果。
如图1至图4所示为现有取暖器100’结构示意图，整体结构主要由散热片10’、热源30’和位于散热片上的上盖20’组成。散热片为周期结构，每个周期单元的基本形状一样，均为由内侧(靠近热源)向外侧渐缩的趋势。热源位于两侧散热片之间，一般为厚度较薄的发热体，通电后温度可达200摄氏度以上，高温热源的热量通过散热片传递到空气到达用户取暖的目的，这个过程中散热片和空气都被加热。
由以上结构可知，当热源通电发热后，热量通过散热片的散热效果传递到空气达到取暖目的。但是该散热片结构还存在散热不充分导致散热片的边缘(面向用户的一端)温度过高，对用户造成潜在的烫伤危险。
发明内容
本发明旨在至少解决现有技术中存在的技术问题之一。
为此，本发明的目的在于提供一种取暖器。
为实现上述目的，本发明的实施例提供了一种取暖器，包括：热源；和多个间隔设置的第一散热片，设置在所述热源的一侧；其中，相邻两个所述第一散热片之间形成散热腔，所述散热腔包括第一端部和第二端部，所述散热腔的第一端部开口，且所述散热腔的第一端部的宽度小于所述散热腔的第二端部的宽度，其中，所述散热腔的第一端部远离所述热源设置，所述散热腔的第二端部靠近所述热源设置。
本发明上述实施例提供的取暖器，多个第一散热片间隔设置，并位于热源的同一侧，热源产生的热量传递到第一散热片，并经第一散热片传递到空气，实现取暖效果。散热腔的第一端部的宽度小于散热腔的第二端部的宽度，即散热腔的第一端部的横截面积小于散热腔的第二端部的横截面积，即散热腔的横截面呈第一端部小、第二端部大的形状。而相关技术中，由于第一散热片第一端部的横截面积小、第二端部的横截面积大，导致相邻两个第一散热片之间围设出的散热腔的第一端部的横截面积大于第二端部的横截面积。相比于相关技术，本申请中空气在散热腔中自下而上运动时，更能够充分利用烟囱效应，增大空气在散热腔中的流动量，从而增大空气带走的热量，同时强化侧面的空气进入散热腔内，降低第一散热片的温度，尤其是降低第一散热片的第一端部最边缘的温度。沿热源的厚度方向，第一散热片包括相对设置的第一端部和第二端部，第一散热腔片的第一端部远离热源，第一散热片的第二端部靠近热源，即第一散热片的第一端部对应散热腔的第一端部、并靠近使用者设置，第一散热片的第二端部对应散热腔的第二端部，这样，第一散热片的第一端部的温度也会降低，从而避免第一散热片的第一端部的边缘温度过高造成取暖器使用中的危险，提高取暖器使用的安全性。

第一散热本体的第一端部对应第一散热片的第一端部和散热腔的第一端部，第一散热本体的第二端部对应第一散热片的第二端部和散热腔的第二端部。第一散热本体的第一端部向外延伸形成延伸部，这样一方面增大了第一散热片第一端部的散热面积，从而增强第一端部与空气之间的热传递面积，进一步降低第一端部的温度，避免第一端部的边缘温度过高，另一方面，延伸部的形成使得散热腔的第一端部的宽度小于散热腔的第二端部的宽度。

优选地，第一散热片2、热源1和第二散热片3上分别设有第一连接孔、第二连接孔和第三连接孔，紧固件穿过第一连接孔、第二连接孔和第三连接孔，以连接第一散热片2、第二散热片3和热源1，使热源1夹在第一散热片2和第二散热片3之间。
优选地，第一散热片2与热源1相卡接；和/或，第二散热片3与热源1相卡接。优选地，第一散热片2的第二端部延伸形成第一连接部24，相邻两第一散热片2的第一连接部24相卡接或通过紧固件相连接或相焊接。

实施例二：
与实施例一的不同在于，如图15至图22所示，第一散热本体的第一端部向一侧延伸形成延伸部23。
优选地，如图21和图22所示，相邻两第一散热本体向其同一侧延伸形成延伸部23，或者，如图15和图16所示，相邻两个第一散热本体相向延伸形 成延伸部23。
当第一散热本体的第一端部向一侧延伸形成延伸部23时，相邻两个第一散热本体可以分别向自身的同一侧延伸形成延伸部23，即相邻两个第一散热本体同向延伸，此时，延伸部23位于与其相连的第一散热本体的同一侧。或者，相邻两个第一散热本体分别向相反的方向延伸形成延伸部23，此时相邻两个第一散热本体的延伸部23相向设置。
优选地，第一散热本体的第一端部与第一散热本体的第二端部之间的距离(如图17中N所示)的范围为50mm～75mm，优选地，第一散热本体的第一端部与第一散热本体的第二端部之间的距离为50mm、55mm、60mm、65mm、70mm、75mm，第一散热本体的第一端部与第一散热本体的第二端部之间的距离与取暖器100的发热功率有关，还与延伸部23的设置情况有关，具体地，相邻第一散热本体分别向其同一侧延伸形成延伸部23时，若发热功率为2000W，第一散热本体的第一端部与第一散热本体的第二端部之间的距离的范围为50mm～70mm，相邻两个第一散热本体相向延伸形成延伸部23时，若发热功率为2000W，第一散热本体的第一端部与第一散热本体的第二端部之间的距离的范围为55mm～75mm。
优选地，散热腔4的第一端部具有开口，且散热腔4的开口宽度与位于散热腔4内的延伸部23的宽度的比值的范围为1/3～1/4，即散热腔4第一端部处，散热腔4的开口宽度与遮挡部分(延伸部23对散热腔4的第一端部进行遮挡)的宽度之比为1/3～1/4，优选地，开口宽度与遮挡部分的宽度的比值为1/3或1/4。
如图18所示，延伸部和第一连接部、第二连接部上设有加强筋，如图19和图20所示，第一散热本体上设有加强筋。
综上所述，本发明实施例提供的取暖器100，第一散热片2第一端部的横截面积大于第二散热片3第二端部的横截面积，从而增大第一端部与空气之间的散热面积，降低第一端部边缘的温度，且相邻两个第一散热片2之间的形成的散热腔4的第一端部的横截面积小于第二端部的横截面积，进一步利用烟囱效应降低第一散热片2第一端部边缘的温度。
