Abstract:
(EN) A heating filter assembly (202) to be mounted on a urea tank (201), comprising a mounting base (4), a heating pipe (5), a urea pipe (6) and a filter (204) accommodated in the mounting base (4). The mounting base (4) is provided with a cooling liquid inlet fitting (41) and a cooling liquid outlet fitting (42) which are connected to the heating pipe (5); the urea pipe (6) is provided with a urea solution inlet (61) which is positioned at the upstream of the filter (204); the mounting base (4) is also provided with a urea solution outlet (43) which is positioned at the downstream of the filter (204); the heating filter assembly (202) comprises a metal thermal conducting cylinder (7) for accommodating the filter (204), and the metal thermal conducting cylinder (7) is provided with an outer wall (71); and the heating filter assembly (202) further comprises a thermal conducting member (8) connecting the outer wall (71) and the heating pipe (5). The heating filter assembly (202) defines a relatively small internal volume by means of the metal thermal conducting cylinder (7), and a part of heat is transferred into the metal thermal conducting cylinder (7) by means of the thermal conducting member (8) so as to heat and thaw urea therein. The present invention has a simple structural design and conveniently facilitates heating.
(FR) Ensemble filtre chauffant (202) destiné à être monté sur un réservoir d'urée (201), comprenant une base de montage (4), un tuyau de chauffage (5), un tuyau d'urée (6) et un filtre (204) logé dans la base de montage (4). La base de montage (4) est pourvue d'un raccord d'entrée de liquide de refroidissement (41) et d'un raccord de sortie de liquide de refroidissement (42) qui sont reliés au tuyau de chauffage (5); le tuyau d'urée (6) est pourvu d'une entrée de solution d'urée (61) qui est positionnée en amont du filtre (204); la base de montage (4) est également pourvue d'une sortie de solution d'urée (43) qui est positionnée en aval du filtre (204); l'ensemble filtre chauffant (202) comprend un cylindre thermoconducteur métallique (7) destiné à recevoir le filtre (204), et le cylindre thermoconducteur métallique (7) est pourvu d'une paroi externe (71); et l'ensemble filtre chauffant (202) comprend en outre un élément thermoconducteur (8) reliant la paroi externe (71) et le tuyau de chauffage (5). L'ensemble filtre chauffant (202) définit un volume interne relativement petit au moyen du cylindre thermoconducteur métallique (7), et une partie de la chaleur est transférée dans le cylindre thermoconducteur métallique (7) au moyen de l'élément thermoconducteur (8) de manière à chauffer et à décongeler l'urée à l'intérieur de celui-ci. La présente invention présente une conception structurale simple et facilite de manière pratique le chauffage.
(ZH) 一种用以安装于尿素箱(201)上的加热过滤组件(202),其包括安装座(4)、加热管(5)、尿素管(6)以及容纳在安装座(4)内的过滤器(204),安装座(4)设有与加热管(5)连接的冷却液进口接头(41)以及冷却液出口接头(42),尿素管(6)设有位于过滤器(204)的上游的尿素溶液入口(61),安装座(4)还设有位于过滤器(204)的下游的尿素溶液出口(43),加热过滤组件(202)包括用以容纳过滤器(204)的金属导热筒(7),金属导热筒(7)设有外壁(71),加热过滤组件(202)还包括连接外壁(71)与加热管(5)的导热件(8)。该加热过滤组件(202)通过金属导热筒(7)限定了一个相对较小的内部体积,一部分热量通过导热件(8)传递到金属导热筒(7)中,以对其内的尿素进行加热解冻,结构设计简单、加热方便。
